Wherein, the desulfurization unit 200 can be connected to the stack 210, so that the flue gas is finally discharged from the stack 210.
In this embodiment, the desulfurization device 200 is a desulfurization tower, and the temperature of the flue gas is 300 ℃ to 400 ℃.
As shown in fig. 1, the dust removing device 300 and the atomizing device 500 are both disposed in the flue 100, the atomizing device 500 is located at the inlet end of the dust removing device 300, and the atomizing device 500 is communicated with the water outlet end of the desulfurization device 200 through a first pipeline 700. Therefore, the desulfurization waste water is finally atomized and sprayed out from the outlet end of the desulfurization device 200 through the first pipeline 700 by the atomization device 500, the desulfurization waste water is atomized into liquid drops with a certain particle size by the atomization device 500, the liquid drops are rapidly evaporated, gasified and crystallized under the high-temperature action of the flue gas of the flue 100, meanwhile, heavy metal molecules are combined with ash in the flue gas and then fall into the dust removal device 300, and water vapor is discharged to the atmosphere along with the flue gas. Through the process, the amount of heavy metals in the desulfurization wastewater is efficiently treated, and the dust removal efficiency is improved.
The first pipe 700 is provided with a flow regulator for regulating a flow rate, the inlet end of the dust removing device 300 is provided with a first temperature detecting element 610, and the first temperature detecting element 610 is communicably connected to the flow regulator. The first temperature detection element 610 may be a temperature sensor, a thermocouple, or another element capable of detecting temperature. In this way, the flow rate of the desulfurization waste water in the first pipeline 700 can be adjusted by automatically controlling the flow rate adjusting member according to the temperature of the flue gas detected by the first temperature detecting element 610.
Wherein, the flow regulating member may be a control valve, and the flow of the desulfurization wastewater in the first pipeline 700 is changed by adjusting the opening of the control valve. Specifically, in the case where the temperature of the flue gas rises, the opening degree of the control valve increases; in case the flue gas temperature decreases, the opening of the control valve decreases.

In an alternative embodiment, in the case that the temperature of the flue gas detected by the first temperature detecting element 610 is higher than a first preset temperature, the control device controls the flow rate adjusting member to increase the fluid flow rate of the first pipeline 700; in case the temperature of the flue gas detected by the first temperature detecting element 610 is lower than the second preset temperature, the control means controls the flow rate adjusting member to decrease the fluid flow rate of the first pipe 700. Wherein the first preset temperature is higher than the second preset temperature.
It should be noted that the "first preset temperature" and the "second preset temperature" are not fixed values, and can be set according to the needs of the user.
So set up, controlling means can carry out automatic control to the flow control spare according to the detection temperature of first temperature detect element 610, adjusts more timely and accurate, adjusts efficiently. Moreover, under the condition that the temperature of the flue gas is higher, the heat of the flue gas is increased, and the flow of the desulfurization wastewater can be increased through the flow regulating piece, so that the sufficient amount of the desulfurization wastewater can be ensured to absorb the heat of the flue gas, and the waste of the heat of the flue gas is avoided.
In this embodiment, as shown in fig. 1, the desulfurization and dust removal system further includes a pump body 900, the pump body 900 is disposed in the first pipeline 700, an inlet end of the pump body 900 is communicated with the water outlet end of the desulfurization device 200, and an outlet end of the pump body 900 is communicated with the heating device 400. Specifically, the water outlet end of the desulfurization device 200 is located lower than the flue 100, so that the desulfurization waste water reaches the atomization device 500 in the flue 100 from the water outlet end of the desulfurization device 200, and the desulfurization waste water needs to be pressurized to reach a higher position.

That is, the desulfurization waste water is directly heated by the heating device 400 during the circulation of the first pipe 700, and the temperature of the desulfurization waste water is increased. Specifically, the heating device 400 may be a heater, and may also be another heating device 400.
So set up, preheat earlier desulfurization waste water before atomizing through heating device 400, avoid the too low desulfurization waste water atomization of temperature to evaporate gasification untimely under the effect of flue gas heat, and can't evaporate to dry before getting into dust collector 300.
Optionally, a heating device 400 is disposed in flue 100, and heating device 400 is located between the flue gas inlet end and dust removal device 300. That is, the heat of the flue gas passes through the heating device 400, and the heat of the flue gas heats the desulfurization waste water while the heating device 400 heats the desulfurization waste water. Of course, in other embodiments, the heating device 400 may be located between the dust removing device 300 and the desulfurization tower as long as it is located in the flue 100 so that the desulfurization waste water can absorb heat of the flue gas.

The dust-proof layer 420 is arranged on the outer surface of the heating body 410, at least part of the dust-proof layer 420 faces the smoke of the flue 100, and the material of the dust-proof layer 420 is a heat conducting material. Alternatively, the dust-proof layer 420 may be disposed on the surface of the heating body 410 facing the flue 100, or the dust-proof layer 420 may surround the entire heating body 410, as long as the dust-proof layer 420 blocks the flue gas from contacting the heating body 410 on the side of the heating body 410 facing the flue gas.
Also, the dust-proof layer 420 may be a dust-proof mesh, and the material of the dust-proof mesh may be metal. Of course, other materials capable of conducting heat are also possible. Specifically, the entire heating device 400 may be directly placed in the flue 100, or may be fixed in the flue 100 by a fixing structure.
Due to the arrangement, the structure of the heating device 400 is refined, the whole structure is simple, and when the heating body 410 heats the desulfurization wastewater, the heat of the flue gas can be transferred to the heating body 410 through the dust-proof layer 420 and finally transferred to the desulfurization wastewater; moreover, the dust-proof layer 420 protects the heating device 400 from dust and prevents the dust in the flue gas from entering the heating device 400 and damaging the performance of the heating body 410.
Optionally, the dust-proof layer 420 can be bonded on the surface of the heating body 410 through heat-conducting glue, and through the heat-conducting glue, the connection between the dust-proof layer 420 and the heating body 410 can be realized, and the heat of the dust-proof layer 420 can be transferred to the heating body 410 to finally heat the desulfurization wastewater.
In the solution of the present application, as shown in fig. 1, the flow rate adjusting element includes an electric control valve 710 and a manual control valve 810, wherein the electric control valve 710 is disposed on the first pipeline 700, and the electric control valve 710 is communicably connected to the first temperature detecting element 610, that is, the opening degree of the electric control valve 710 is adjusted according to the temperature of the flue gas detected by the first temperature detecting element 610, so as to adjust the flow rate of the first pipeline 700.
The desulfurization and dust removal system further comprises a second pipeline 800, one end of the second pipeline 800 is communicated with the atomization device 500, the other end of the second pipeline 800 is connected with the water outlet end of the desulfurization device 200, and the manual control valve 810 is arranged on the second pipeline 800. That is, the second pipeline 800 is connected in parallel with a part of the first pipeline 700, the desulfurization wastewater flowing out from the water outlet end of the desulfurization device 200 can flow through the heating device 400 via the second pipeline 800 and finally reach the atomizing device 500, and the opening degree of the second pipeline 800 is adjusted by the manual control valve 810.
So set up, electric control valve 710 and manual control valve 810 do not influence each other, and the flow that all can adjust the desulfurization waste water that flows through heating device 400, so under the unable circumstances of using of electric control valve 710 problem, accessible manual control valve 810 replaces electric control valve 710 to control, makes things convenient for electric control valve 710 to overhaul.
In the present embodiment, the heating body 410 is communicably connected to the first temperature detecting element 610, and specifically, the control device may be communicably connected to both the heating body 410 and the first temperature detecting element 610. When the temperature of the flue gas detected by the first temperature detecting element 610 is high, the control device controls the heating degree of the heating body 410 to increase; when the temperature of the flue gas detected by the first temperature detecting element 610 is low, the control device controls the degree of heating of the heating body 410 to be reduced.
So, when flue gas temperature is higher, along with the aperture increase of flow control spare, the flow increase of first pipeline 700, the desulfurization waste water volume increase of heating body 410 is flowed through to the same time, if the heating degree of heating body 410 is invariable, then, the temperature of desulfurization waste water can reduce in first pipeline 700, increases the heating degree of heating body 410 at this moment to guarantee that desulfurization waste water keeps suitable preheating temperature in first pipeline 700, avoid preheating temperature to hang down excessively.
Similarly, when the flue gas temperature is lower, along with the opening degree of the flow regulating member being reduced, the flow of the first pipeline 700 is reduced, the amount of the desulfurization wastewater flowing through the heating body 410 at the same time is reduced, and if the heating degree of the heating body 410 is still constant, the temperature of the desulfurization wastewater in the first pipeline 700 is increased, so that the heating degree of the heating body 410 is reduced, thereby ensuring that the desulfurization wastewater in the first pipeline 700 keeps a proper preheating temperature and avoiding an excessively high preheating temperature.
In a further embodiment, as shown in fig. 1, the first pipeline 700 is provided with a second temperature detecting element 620 for detecting the temperature of the fluid, the temperature of the desulfurization waste water in the first pipeline 700 can be detected by the second temperature detecting element 620, and at least one of the flow rate adjusting member and the heating device 400 is communicably connected to the second temperature detecting element 620. The second temperature detection element 620 may be a temperature sensor, a thermocouple, or another element capable of detecting temperature.
Alternatively, the second temperature detecting element 620 may be communicably connected to the electric control valve 710, in which case the flow rate of the desulfurization waste water in the first pipeline 700 can be adjusted by adjusting the opening degree of the electric control valve 710 according to the temperature of the desulfurization waste water detected by the second temperature detecting element 620.
Specifically, under the condition that the fluid temperature detected by the second temperature detecting element 620 is higher than the third preset temperature, it is indicated that the preheating temperature of the desulfurization wastewater in the first pipeline 700 is higher, at this time, the opening degree of the electric control valve 710 is increased, the flow rate of the desulfurization wastewater in the first pipeline 700 is increased, and the heating body 410 heats more desulfurization wastewater within the same time, so that the preset temperature of the desulfurization wastewater can be effectively reduced, and the preheating temperature is prevented from being too high.
Under the condition that the fluid temperature detected by the second temperature detecting element 620 is lower than the fourth preset temperature, it is indicated that the preheating temperature of the desulfurization wastewater in the first pipeline 700 is lower, at this time, the opening degree of the electric control valve 710 is reduced, the flow rate of the desulfurization wastewater in the first pipeline 700 is reduced, and the heating body 410 heats a smaller amount of desulfurization wastewater within the same time, so that the preset temperature of the desulfurization wastewater can be effectively increased, and the preheating temperature is prevented from being too low.
It should be noted that the "third preset temperature" and the "fourth preset temperature" are not fixed values, and can be set according to the needs of the user.
Alternatively, the second temperature detecting element 620 may be communicably connected to the heating device 400, in which case the heating degree of the desulfurization waste water by the heating body 410 can be adjusted according to the temperature of the desulfurization waste water detected by the second temperature detecting element 620.
Specifically, in the case that the fluid temperature detected by the second temperature detecting element 620 is higher than the third preset temperature, which indicates that the preheating temperature of the desulfurization wastewater in the first pipeline 700 is higher, the heating body 410 reduces the heating degree of the desulfurization wastewater, thereby reducing the preheating temperature of the desulfurization wastewater; in the case where the fluid temperature detected by the second temperature detecting element 620 is lower than the fourth preset temperature, which indicates that the preheating temperature of the desulfurization wastewater in the first pipeline 700 is low, the heating device 400 increases the heating degree of the desulfurization wastewater, thereby increasing the preheating temperature of the desulfurization wastewater.
In this embodiment, the second temperature detecting element 620 may be communicatively connected to both the electric control valve 710 and the heating apparatus 400. In this case, the opening degree of the electric control valve 710 and the heating degree of the heating body 410 can be adjusted according to the temperature of the desulfurization waste water detected by the second detection element.
Specifically, when the temperature of the fluid detected by the second temperature detecting element 620 is higher than the third preset temperature, the opening degree of the electric control valve 710 is increased, the flow rate of the desulfurization wastewater in the first pipeline 700 is increased, and the heating degree of the heating body 410 is reduced, so that the temperature of the desulfurization wastewater is rapidly reduced to a suitable range; in the case where the temperature of the fluid detected by the second temperature detecting element 620 is lower than the fourth preset temperature, the opening degree of the electric control valve 710 is decreased, the flow rate of the desulfurization wastewater in the first pipeline 700 is decreased, and the heating degree of the heating body 410 is increased, so that the temperature of the desulfurization wastewater is rapidly increased to a suitable range.
