Referring to fig. 1 to 4, a water softening apparatus in one embodiment includes a jet device 100, a multi-way valve 200, a salt supply device 300, and a resin tank 400, wherein the jet device 100 is respectively communicated with the multi-way valve 200 and the salt supply device 300, the multi-way valve 200 is communicated with the resin tank 400, brine is loaded in the salt supply device 300, and soft water resin is loaded in the resin tank 400. Wherein, a plurality of different channels are arranged in the multi-way valve 200, and the switching of the working states of water supply, regeneration, slow washing, water replenishing and the like of the water softening equipment is realized through the switching of the plurality of different channels.
It should be noted that, referring to fig. 1, when the water softening apparatus is in a water supply state, raw water flows into the resin tank 400 through the multi-way valve 200, hardness ions (calcium ions, magnesium ions, etc.) in the raw water exchange with sodium ions in soft water resin in the resin tank 400, and the hardness ions in the raw water are adsorbed and exchanged by the soft water resin, so as to achieve the purpose of outputting soft water after the raw water is softened;
after ion exchange to produce a certain amount of soft water, the soft water resin is saturated with hardness ions, at which point resin regeneration is required. Referring to fig. 2 and 3, when the water softening apparatus is in a regeneration state, a regeneration liquid formed by mixing raw water with brine flows into the resin tank 400 through the ejector 100 and the multi-way valve 200, and hardness ions (calcium ions, magnesium ions, etc.) adsorbed by the resin are replaced with ions (sodium ions) in the regeneration liquid, thereby restoring the softening capacity of the soft water resin, and thus realizing regeneration of the soft water resin.
Referring to fig. 2 and 3, the water softening apparatus in one embodiment has at least two regeneration states capable of generating regeneration liquids with different concentrations, and referring to fig. 6, the ejector 100 has at least two jet flow channels with different jet flow areas, and the multi-way valve 200 has regeneration passages communicated with the different jet flow channels.
The flow guide linkage control method is applied to linkage control of the ejector 100 and the multi-way valve 200, and comprises the following steps:
s1, controlling the water softening equipment to operate in a regeneration state Z1, opening a corresponding jet flow channel to mix raw water and salt water to form regeneration liquid with a concentration, and synchronously opening a regeneration channel communicated with the current jet flow channel to execute a first regeneration action of the soft water resin;
s2, the water softening equipment can be switched to another regeneration state Z2 to operate, one corresponding jet flow channel is opened to enable the raw water and the salt water to be mixed to form regeneration liquid with another concentration, and a regeneration channel communicated with the current jet flow channel is synchronously opened to execute a second regeneration action of the soft water resin.
According to the flow guide linkage control method, after the regeneration state is started, the regeneration state can be switched to different regeneration states according to actual needs, different jet flow channels are selectively opened to control the flow of the saline water entering the jet device 100, so that the saline water is mixed with the same amount of raw water and regeneration liquid with different concentrations is provided, the regeneration liquid flows to the soft water resin through the regeneration channel communicated with the current jet flow channel, and the utilization rate of the saline water is improved and the regeneration rate is improved.
For example, when different regeneration liquids with different concentrations from large to small are required to be supplied to the water softening equipment, the jet flow channel with a smaller jet flow area is firstly opened to operate so as to suck more salt water to be mixed with raw water, thereby forming a high-concentration regeneration liquid, and the high-concentration regeneration liquid enters the resin tank 400 through the multi-way valve 200 to be subjected to sufficient ion exchange; and along with the continuous going on of regeneration, the ion that needs to carry out the exchange also reduces thereupon, switches to opening the efflux runner operation that has great flow area this moment to inhale less salt water and raw water mixture, thereby form low concentration regeneration liquid, low concentration regeneration liquid passes through in the multiple unit valve 200 gets into resin tank 400, and it can not cause the salt extravagant to provide the regeneration liquid that concentration is less at this stage, can not hinder regeneration effect yet, more is favorable to improving the utilization ratio of salt water and promoting the regeneration rate.
For another example, when different regeneration liquids with different concentrations from small to large are required to be supplied to the water softening equipment, a jet flow channel with a larger jet flow area is firstly opened for operation so as to suck less saline water to be mixed with raw water, thereby forming a low-concentration regeneration liquid; and along with the continuous progress of regeneration, switch to open the operation of the efflux runner that has less flow area to inhale more salt solution and raw water mixture, thereby form high concentration regeneration liquid.
Specifically, in an embodiment, referring to fig. 5, the ejector 100 has a mixing chamber 101, a salt supply pipeline 120 connected to the mixing chamber 101, an outlet pipeline 130, and at least two inlet pipelines 110, wherein different inlet pipelines 110 have different jet areas, the outlet pipeline 130 is connected to the multi-way valve 200, and the salt supply pipeline 120 is connected to the salt supply device 300 of the water softening plant.
Referring to fig. 6 and 7, when the water softening apparatus is in any regeneration state, one of the water inlet pipes 110 corresponding to the water softening apparatus is opened in a matching manner, raw water flows to the mixing chamber 101 through the water inlet pipe 110 and generates a negative pressure effect, brine of the salt supply device 300 enters the mixing chamber 101 through the salt supply pipe 120 under the negative pressure effect and is mixed with the raw water to form a regeneration liquid, and the regeneration liquid flows to the regeneration channel communicated with the current water outlet pipe 130 through the water outlet pipe 130.
In this way, by making the jet areas of the different water inlet pipes 110 different, different negative pressures can be generated when raw water flows into the water inlet pipe 110, and the flow rate of the brine sucked into the salt supply pipe 120 is controlled, so that the brine is mixed with the same amount of raw water and the regeneration liquid with different concentrations can be provided.
For example, referring to fig. 8 and 7, when the water inlet pipeline 110a with a smaller jet flow area is opened, the raw water flows through the water inlet pipeline 110a to form a stronger negative pressure effect, so that more saline water is sucked into the salt supply pipeline 120 to be mixed with the raw water, thereby forming a high-concentration regeneration liquid; when the water inlet pipeline 110b with a larger jet flow area is opened, raw water flows through the water inlet pipeline 110b to form a weaker negative pressure effect, so that less saline water is sucked into the salt supply pipeline 120 and is mixed with the raw water, and low-concentration regeneration liquid is formed.
Preferably, the inlet conduit 110 and the outlet conduit 130 are small bore conduits, such as capillary tubes. When the water softening apparatus is in a regeneration state, raw water enters the mixing chamber 101 from the water inlet pipe 110, a siphon force is generated on the capillary tube, and salt water enters the mixing chamber 101 through the salt supply pipe 120 under the action of the siphon force and is mixed with the raw water to form a regeneration liquid.
In this embodiment, referring to fig. 5, at least two water outlet pipes 130 are provided, and at least two jet flow channels with different jet areas are formed by all the water inlet pipes 110, the mixing chamber 101 and all the water outlet pipes 130. When the water softening equipment is in any regeneration state, one water inlet pipeline 110, one water outlet pipeline 130 and one regeneration channel corresponding to the water softening equipment are opened in a matching manner.
Thus, different jet areas are formed by selectively opening different inlet conduits 110 and outlet conduits 130. The flow or the concentration of the regeneration liquid that flows through under the different jet areas are inequality, can input the regeneration liquid of different volume or different concentration according to the demand of the different stages of regeneration process to the dynamic change of ion exchange reaction in the better adaptation regeneration process reduces the extravagant and regeneration effect of salt good, can promote regeneration efficiency.
In this embodiment, the water outlet pipes 130 are arranged in a one-to-one correspondence with the water inlet pipes 110, and when one of the water inlet pipes 110 is opened to form a regenerated liquid with a lower concentration, the water outlet pipe 130 specially used for circulating the regenerated liquid with a lower concentration is correspondingly opened; when another water inlet pipeline 110 is opened to form the regeneration liquid with higher concentration, a water outlet pipeline 130 specially used for circulating the regeneration liquid with higher concentration is correspondingly opened. Through this setting, can form the water inlet and the delivery port of different concentration to avoid the influence each other between each different concentration regeneration liquid.
For example, referring to fig. 5 and 2, when different regeneration liquids with different concentrations from large to small are required to be provided to the water softening plant, the water inlet pipeline 110a and the water outlet pipeline 130a with small flow areas are opened first, the salt supply pipeline 120 sucks more salt water to mix with the raw water, the raw water and the salt water entering the mixing chamber 101 are mixed in the mixing chamber 101 to form a high-concentration regeneration liquid, and the regeneration liquid enters the regeneration passage R1 of the multi-way valve 200 through the water outlet pipeline 130a, so as to form a jet flow channel from the water inlet pipeline 110a, the salt supply pipeline 120, the mixing chamber 101 and the water outlet pipeline 130 a;
as the regeneration continues, referring to fig. 5 and 3, the ions to be exchanged are reduced, and at this time, the water inlet pipe 110b and the water outlet pipe 130b with larger flow areas are switched to open, the salt supply pipe 120 sucks less salt solution to mix with the raw water, the raw water and the salt solution entering the mixing chamber 101 are mixed in the mixing chamber 101 to form low-concentration regenerated solution, and the regenerated solution enters the regeneration channel R2 of the multi-way valve 200 through the water outlet pipe 130b, so as to form another jet flow channel from the water inlet pipe 110b, the salt supply pipe 120, the mixing chamber 101, and the water outlet pipe 130 b.
It should be noted that the different water outlet pipes 130 may have different or the same jet areas, and at least two jet flow channels with different jet areas can be formed by making the different jet areas of the different water inlet pipes 110b different.
Specifically, referring to fig. 5, the ejector 100 further includes a first switching member (not shown) for opening and closing different jet flow passages. When the water softening equipment is in any regeneration state, the first switching piece is controlled to open the corresponding jet flow channel in a matching way. In this way, the first switch opens different inlet and outlet pipes 110 and 130, so as to open different jet flow paths in a matching manner.
Preferably, the first switching element is a four-way valve or other type of valve.
More specifically, referring to fig. 3, the multi-way valve 200 further includes a second switching member for opening and closing different regeneration passages. When the water softening equipment is in any regeneration state, the second switching piece is controlled to open the regeneration channel communicated with the current jet flow channel in a matching manner.
In some embodiments, the second switching element includes a movable valve plate and a fixed valve plate, the movable valve plate moves relative to the fixed valve plate, the movable valve plate and the fixed valve plate are both provided with channel holes, and the channel holes which are matched and communicated between the movable valve plate and the fixed valve plate are adjusted to open different regeneration channels in a matching manner. In other embodiments, the second switching member may be provided in any other structure, which is not limited herein.
In this embodiment, referring to fig. 5 and 4, the water softening apparatus further has a water replenishing state, and when the brine in the salt supply device is smaller than the first preset value in any regeneration state, the water softening apparatus is automatically switched to the water replenishing state to operate.
It is understood that, in the process of regenerating the resin by performing ion exchange, the raw water is mixed with the brine outputted from the salt supplying device 300 to form a regenerated liquid; when the brine in the brine supply device 300 is used for a period of time, the brine in the brine supply device 300 needs to be replenished.
It should be noted that no matter what regeneration state the water softening equipment is, when the brine in the salt supply device 300 is smaller than the first preset value, the water softening equipment is controlled to be automatically switched to the water replenishing state, so that the situation that resin regeneration cannot be continued is effectively avoided, and intelligent control is realized.
Specifically, referring to fig. 5 and 4, the multi-way valve also has a refill passage B1 in communication with the outlet line 130. When the water softener is in the water replenishing state, the water outlet pipeline 130 is selectively opened and the water replenishing channel B1 is synchronously opened, so that the raw water flows into the salt supplying device 300 through the water replenishing channel B1, the water outlet pipeline 130, the mixing chamber 101 and the salt supplying pipeline 120 in sequence to perform the water replenishing action.
Therefore, the water outlet pipeline 130, the mixing cavity 101 and the salt supply pipeline 120 form a water supplementing flow channel which has the opposite flow direction to the jet flow channel, the water supplementing flow channel and the jet flow channel share the mixing cavity 101, and a plurality of different water channel channels are prevented from being arranged in the water softening equipment, so that the structure of the water softening equipment is simplified.
In this embodiment, referring to fig. 10, the step of controlling the water softening plant to operate in a regeneration state Z1 further includes:
s11, the water softening equipment is also provided with a water supply state, and the water softening equipment is controlled to operate in the water supply state to output soft water;
and S12, when the water supply state is operated until the soft water output is less than the second preset value, the water softening equipment automatically switches to a regeneration state Z1 for operation.
It can be understood that when the water softening apparatus is in a water supply state, raw water flows into the resin tank 400 through the water supply passage B1, hardness ions (calcium ions, magnesium ions, etc.) in the raw water exchange with sodium ions in the soft water resin in the resin tank 400, and the hardness ions in the raw water are exchanged by adsorption of the soft water resin; after ion exchange to produce a certain amount of soft water, the soft water resin is saturated with hardness ions, and regeneration of the soft water resin is required. Through the setting, the condition that raw water cannot be continuously softened is effectively avoided, and intelligent control is realized.
Specifically, referring to fig. 1, the multi-way valve further has a water supply passage G1, and when the water softening apparatus is in a water supply state, the water supply passage G1 is opened, and raw water flows through the soft water resin from the water supply passage G1 and outputs the soft water to perform a water supply operation.
In this embodiment, referring to fig. 10, the step after the regeneration state Z1 reaches the running time T1 further includes:
s13, the water softening equipment is also in a slow washing state, and the water softening equipment is switched to the slow washing state when the operation time of the water softening equipment in the regeneration state Z1 reaches T1;
s14, when the running time of the slow washing state reaches T2, the regeneration state is switched to another regeneration state Z2 for running.
Specifically, referring to fig. 9, the multi-way valve further has a slow washing passage M1; when the water softening apparatus is in the slow washing state, the slow washing passage M1 is opened, and the raw water flows to the soft water resin through the slow washing passage M1 to perform a slow washing action.
It will be appreciated that after ion exchange to regenerate the resin, the solution containing the calcium and magnesium ions under exchange needs to be drained quickly. When the water softening device is in the slow washing state, raw water is controlled to enter the resin tank 400 through the slow washing channel M1, and the resin is slowly washed from bottom to top so as to take away the solution containing calcium and magnesium ions and residual dirt, and the residual calcium and magnesium ions and the dirt are prevented from influencing the softening effect of the raw water.
In this embodiment, the operation times T1 and T2 may be equal or different, and are designed according to actual requirements.
In this embodiment, referring to fig. 10, the step of switching to another regeneration state Z2 further includes:
s21, when the running time of the other regeneration state Z2 of the water softening equipment reaches T3, switching to the slow washing state to run;
and S22, stopping running in the slow washing state when the operation in the slow washing state is carried out until the regeneration rate of the soft water resin is equal to a third preset value.
In this way, the solution containing calcium and magnesium ions in the regeneration state Z2 needs to be quickly discharged, so that the softening effect of raw water is prevented from being affected by the residual calcium and magnesium ions and dirt, and the resin regeneration rate can be effectively ensured.
It should be noted herein that when the water softening apparatus is in the slow washing state, the slow washing passage M1 is opened, and the raw water flows to the soft water resin through the slow washing passage M1 to perform the slow washing action.
In this embodiment, the operation times T3 and T2 may be equal or unequal, and are designed according to actual requirements.
In the present embodiment, the regeneration passage R1, the regeneration passage R2, the replenishment passage B1, the water supply passage G1, and the slow wash passage M1 of the multi-way valve are all switched by the second switching piece. Different channel holes are communicated by controlling the second switching piece, so that the regeneration channel R1, the regeneration channel R2, the water replenishing channel B1, the water supply channel G1 and the slow washing channel M1 are selectively opened.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, however, as long as there is no contradiction between the combinations of the technical features, the scope of the present description should be considered as being described in the present specification.
