Open, and by the water outlet of pipeline towards the corresponding filter screen cylinder 49 of cold water area, preferably, its cold water inlet communicates with the brush body that can be communicated with this pipeline, and the brush body is a water-absorbing material as a whole, such as cloth, brush body It is located between the inner wall of the cylinder and the outer wall of the filter cylinder.

The solar waste heat recovery device is characterized by three working modes for different solar radiation values:

1. Normal mode

When the solar radiation intensity is suitable, the control valve 11 41 is closed, and the control valve 12 42 is opened. The device does not need to open the phase change thermal storage device 40, and directly heats the water in the intermediary heat exchange tank 23.

Its main working principle is that at night, the air source heat pump 21 uses the characteristics of low peak and valley electricity prices to heat the hot water in the hot water tank 19. The heat in the tank 19 heats the temperature of the bubble pool. If the requirements cannot be met, then open the control valve 2 7 to directly introduce the high-temperature hot water in the hot water tank 19 into the bubble pool and heat it to ensure the temperature of the bubble pool. Constant, maintained at 38°C to 42°C. When the golf course is opened during the day, the water in the hot water tank 19 is maintained at 44°C to 50°C. Drain valve 1 is used for bubble pool drainage.

The hot water in the hot water tank 19 heats the water in the bubble pool 3 via the circulating water pump 9 through the plate heat exchanger 8 to maintain the water in the bubble pool at 38°C to 42°C. When the water in the bubble pool 3 was not enough, the control valve two 7 could be opened to replenish water in the bubble pool 3 with the water in the hot water tank 19. The bubble pool waste heat recovery device is characterized in that it has the following working modes for daytime and nighttime for different water temperatures in the hot water tank 19:

Heating during the day:

1. No heating mode

When the temperature sensor two 10 measures the water temperature in the hot water tank 19 and reaches 49°C, the control valve five 16 and the control valve six 17 are all closed, and the system closes the air source heat pump 21 and the water source heat pump 20. Only the water in the bubble pool 3 is heated by the heat exchanger 8 .

2. Heating mode

The water source heat pump 20 is preferentially turned on to recover waste heat from the waste water discharged from the bubble pool. After the waste water is circulated and discharged to the main sewage canal, the air source heat pump 21 is turned on to preheat the water in the water tank 19.

The bubble pool wastewater waste heat recovery device includes a water separator 4, a circulation pump 1 5, a circulation pump 9 45, a grassland pipeline 46, a sewage main canal 47, and a water source heat pump 20. Its working principle is that the waste water discharged from the bubble pool of the golf course at night passes through the water separator 4 and partly passes through the circulating pump to heat the grass to prolong the service life of the grass. It is discharged into the main sewage canal 47 afterward.

Aiming at the above system, a golf course waste heat recovery and lawn heating algorithm is proposed. The system consists of a heat storage tank, a bubble pool, an air source heat pump, an electric drive water source heat pump, a plate heat flow valve and water pump.

The heat storage tank is used to store hot water and provide hot water to the bubble pool, and the air source heat pump is used to heat the water in the heat storage tank to maintain the water temperature in the heat storage tank.

The water temperature of the golf course's bubble pool is required to be maintained within a constant range. The heat storage tank provides heat source to the bubble pool. The heater exchanges heat with the pool water to maintain the temperature of the pool water. When the temperature of the bubble pool is too low, the water pump 3 is turned on to directly discharge the hot water of the heat storage tank into the bubble pool to heat up the bubble pool.

When the bubble pool is drained, part of the bubble pool water is sent to the electric-driven water source heat pump, and the waste heat of the bubble pool water is recovered by the electric-driven water source heat pump to heat the heat storage tank.

At night in early autumn in the north, the lower grassland temperature is not suitable for the growth of the lawn, and the part of the bubble pool drained by the diverter 9 is used to heat the lawn and maintain the growth time of the lawn. After the golf course is closed at night, the throttle valve 1 is opened to drain the bubble pool, and the water is divided into two parts by the water separator 9 to the grassland and the electric drive water source heat pump. According to the demand for water temperature of the grassland, the electric drive The water after the water source heat pump is reintroduced into the grassland for maintenance, and the waste heat of the soaking pool water is rationally recycled. The opening degree of the water separator 9 is controlled and determined by a predictive algorithm. When the surface temperature is lower than the suitable growth temperature of the lawn, the water separator 9 drains part of the hot water into the lawn heating pipe to heat up the lawn, so as to avoid the low surface temperature and damage the growth of the lawn. When the surface temperature reaches or is higher than the suitable growth temperature of the grass, the water distributor 9 stops supplying water to the lawn heating pipeline, diverts all the water to the electric-driven water source heat pump, recovers the waste heat from the bubble pool drainage, and heats the water in the heat storage pool.

The basic idea of the algorithm is:

Set the water divider 9 to the following six gears

[1] 100% opening, the largest opening to the grass heating pipe, the largest energy release;

[2] 80% opening;

[3] 60% opening;

[4] 40% opening;

[5] 20% opening;

[6] Closed.

First, set the typical low-temperature working day temperature T _d , and take Dalian as an example to select the nighttime hourly temperature (21:00-6:00 the next day) of the day with the lowest nighttime average temperature in October in the past 10 years as the typical low-temperature working day temperature T _d , the highest gear of the water separator 9 should be able to maintain a suitable temperature for the grassland under typical low-temperature working days. The typical low temperature working day temperature T _d can be found in the following table through the data query provided by Dalian Meteorology:

Table 1: Typical low temperature working day hourly temperature

Set several temperature sensors on the surface of the lawn, turn on 15 minutes before 9:00 to 6:00 the next day, detect the surface temperature T every 1 minute, detect 15 surface temperatures T in 15 minutes, and take the average value to get The actual temperature is measured as the whole point.

control algorithm

When designing the control decision-making algorithm, it is mainly based on the measured temperature The difference between the temperature T _d and the typical low-temperature working day determines the gear position of the water separator. The specific decisions are as follows:

ω—Difference decision coefficient

The relationship between the difference decision coefficient ω and the selection of the 9 gears of the water distributor is as follows:

Table 2: Correspondence between the difference ω and the gear position of the water distributor

From 21:00 to 6:00 the next day, a decision is made every hour, and then the different openings of the water distributor 9 for water supply to the grass are adjusted. At 7:00, the water supply to the grassland is stopped, and the diverter 9 keeps [6]0%, and the opening degree is repeated until 21:00.

For the existing sewage source heat pump, the front-end sewage treatment device will inevitably be blocked, and the heat loss will be large. In order to solve these problems, this embodiment proposes a filter cartridge system for the treatment of bubble pool sewage in golf courses , Two buffer chambers are added on both sides of the filter screen, which greatly reduces the heat energy loss caused by water penetration. Moreover, the use of the vertical barrel filter and the buffer chamber greatly improves the decontamination efficiency of the decontamination machine and accelerates the engineering application of the sewage source heat pump system.

Raw sewage flows in from the hot water inlet, passes through the inner wall of the rotating chamber, and the rotating chamber is driven by the stepping motor to rotate, and the centrifugal force generated makes the dirt in the sewage adhere to the inner wall of the rotating chamber. The filtered raw sewage flows out from the hot water outlet and is used for heat exchange in the back-end heating system. The dirt on the inner wall of the rotating chamber is driven by the filter to rotate from the hot water chamber to the cold water chamber with a chassis gap. The system waste water generated by the heating system flows in from the flushing water inlet. Under the pressure of the booster pump and the flat outlet, it washes inward from the outer wall of the rotating chamber, and carries the dirt in the rotating chamber from the cold water outlet. flow out. The composition of the backwash decontamination machine includes: decontamination machine shell, stepping motor, barrel-shaped filter screen (filter screen cylinder), partition plate welded on the inner wall of the barrel-shaped filter screen, upper cover plate, shaft and set in the decontamination machine shell. The four water outlets/inlets.

details as follows:

Adopt the method of round mouth water inlet and flat mouth water outlet. Because of the strong attachment ability of dirt and debris and the large amount of dirt, such as some hair strands, etc. hanging on the filter, it is difficult to rinse. The round inlet and flat outlet are used. Under the same water flow conditions, the flat inlet is relatively smaller than the round The mouth not only increases the water pressure to increase the washing force, but also can wash a larger area of the filter screen. Moreover, the filter screen rotates under the drive of the spindle motor. During the rotation, the flushing port will have one-sixth of the arc area to flush the same position. Therefore, after increasing the water pressure, there will be almost no dirt and sundries. The chances of dirt adhering to the filter are greatly reduced. In this way, the filtration efficiency can be improved.

There are buffer structures on both sides. Through the transition of the buffer zone, the heat exchange rate of the two chambers can be reduced, and the heat loss during the decontamination process can be reduced, so that the heat obtained from the sewage can be better utilized and can Energy conservation.

It adopts a rotatable cylindrical structure. Different from the flat filter in the past, the cylindrical structure can effectively prevent dirt and debris from entanglement and adhesion on the wall of the barrel, reducing friction, and can also perform 360° flushing without affecting its filtration, which can keep the filter Keep it clean to better filter raw sewage. Moreover, the partitioning of the filter screen can realize the two functions of filtering and cleaning up dirt at the same time, successfully solving the problem of pipeline blockage, fully recovering and utilizing the heat in the sewage, and improving resource utilization.

Cylindrical filter screen, partition, the cross-section shape of the partition divides the rotating chamber into four leaf chambers, each chamber is equivalent to an independent space, and divides the filtered water into four parts, increasing The large contact area also enables the separation of cold water and hot water, improving the efficiency of decontamination.

Specifically, the system is installed in the waste heat recovery device of bubble pool waste water. Specifically, the hot water inlet of the system is connected to the outlet of the main sewage canal to solve the problems of sewage filtration and heat use. Of course, the hot water outlet of the system can be connected with the water source heat pump 20, so that part of the heat energy can be further recovered by the water source heat pump.

This system comprises cylinder body 48, and described cylinder body 48 is cylindrical cylinder body 48 or regular polygonal cylinder body 48, and there is concentric filter screen cylinder 49 in cylinder body 48, between cylinder body 48 inner wall and filter screen cylinder 49 outer walls There is a certain distance, and the bottom of the filter screen cylinder 49 is a cylinder plate, the cylinder plate is connected with the rotating shaft, and the rotating shaft is connected with the motor. The circumferential cylinder wall of the filter screen cylinder 49 has filter holes, and the inner space of the filter screen cylinder 49 is separated The plate 50 is divided into four chambers;

At two relative positions of the cylinder body 48, two buffer zones 51 are set, and the buffer zone 51 is a body-shaped area surrounded by two vertical plates and a vertical partition 50 with an opening at one end, and is fixed by the vertical partition 50. The inner wall of the cylinder body 48, and the upper and lower cylinder covers of the two vertical plates and the cylinder body 48 are all in conflict, and the vertical plate is arranged towards the filter screen cylinder 49, and there is a gap between the filter screen cylinder 49 so as not to hinder the filter screen cylinder 49 Rotating distance in cylinder body 48, and as close as possible to filter screen cylinder 49, the space between the inner wall of cylinder body 48 and the outer wall of filter screen cylinder 49 is divided into two areas on the circumference by two buffer zones 51, one is the hot water area, One is the cold water area. The hot water area is provided with a hot water inlet 52 and a hot water outlet 53. The hot water inlet of the hot water area is located on the upper cover of the cylinder body 48, and is passed into the filter cylinder 49 by a pipeline. The hot water outlet 53 is located at the bottom of the cylinder 48 in the hot water area. The cold water area is provided with a cold water inlet 54 and a cold water outlet 55. The cold water inlet 54 is opened from the wall of the cylinder 48 and is directed by the outlet of the pipe. The filter screen cylinder 49 corresponding to the cold water area, the cold water outlet 55 is located at the bottom of the cylinder body 48 of the cold water area.

In one solution, the water inlet is a round mouth, and the water outlet is a flat mouth.

Raw sewage flows in from the hot water inlet, passes through the inner wall of the rotating chamber, and the rotating chamber is driven by the stepping motor to rotate, and the centrifugal force generated makes the dirt in the sewage adhere to the inner wall of the rotating chamber. The filtered raw sewage flows out from the hot water outlet and can be used for heat exchange in the back-end heating system. The dirt on the inner wall of the rotating chamber is driven by the filter to rotate from the hot water chamber to the cold water chamber with a chassis gap. The system waste water generated by the heating system flows in from the flushing water inlet. Under the pressure of the booster pump and the flat outlet, it washes inward from the outer wall of the rotating chamber, and carries the dirt in the rotating chamber from the cold water outlet. flow out. The system is heated in the hot water area, and brushes the filter in the cold water area by the rotation of the filter cylinder, so that the filtration and cleaning can be separated, the cleaning effect is better, and the heat exchange is small, and the filtered heat can be fully utilized .

The system can adapt to various water flows and sewage flow rates. Compared with ordinary motors, it uses metal gears that are more wear-resistant, less frictional and less noisy than ordinary plastic gears. Secondly, the all-copper coil makes its loss lower, high stability, and longer life. Moreover, because the sewage not only contains water, but also is rich in impurities and soluble liquids with various physical and chemical properties, the density is high. When there is too much sewage, the sewage in the decontamination machine may exceed the working range of ordinary motors, causing the motors to fail. Work or even burn out, and the maximum workload of the high-torque stepper motor we choose can meet the situation where the sewage fills the entire decontamination machine. Moreover, the speed of the stepping motor is adjustable, and the strain can be made in the face of various sewage structures and the speed of the influent water. By adjusting the speed of the stepping motor, the rotation speed of the entire rotating blade chamber can be adjusted to enhance the filtering effect, so that The filter effect can be adjusted, and the adaptable environment can also be rich and varied, which greatly improves the decontamination efficiency of the decontamination machine.

For the pumps in the system, the booster pump can be used to realize the three-speed speed regulation of the shielded circulating water pump. When you want different power, you can adjust the water output rate freely by adjusting the red position. Secondly, it can be intelligently supercharged, energy-saving and environmentally friendly. Moreover, it adopts all-copper coil, stable and reliable motor, precise mechanical design, and has undergone strict standard instrument testing.

There are many decontamination machines, but they all have more or less problems and cannot meet the decontamination needs of sewage source heat pumps. The system in this example is compared with the most common grid type decontamination machine:

Filtration device: The grid type decontamination machine uses a grid for decontamination. Its disadvantages are that it wears heavily, has poor durability, and is easy to hang things, such as hair and other filamentous substances. The filtering device used in the system of this embodiment is a barrel-shaped filter net, which is equivalent to a curved surface, so that the dirt and sundries want to hang on it, but there is no way to do it. Good sex.

Impurity removal method: The impurity removal of the grid-type decontamination machine is divided into two steps. First, rely on gravity to fall, and some solid impurities can fall freely under the action of gravity, and then rely on the reverse movement of the cleaner to remove the grid Sweep off part of the dirt and debris on the surface to achieve impurity removal. This impurity removal method will not only make the cleaner and the grille repeatedly contact and reduce the service life, but also the decontamination is not thorough and easy to block. The cleaner is a rigid substance, and the grille is not a smooth surface, which will cause the two not to be in full contact, and thus the impurity removal will not be complete. According to statistics, the clogging rate of the grid type decontamination machine is about 10% per day. In order to avoid this problem, our decontamination machine uses system wastewater for backwashing. Water, a flexible substance, can fully contact the filter to achieve the purpose of complete decontamination.

Dirt treatment: The dirt and debris filtered out by the grid-type decontamination machine will fall on the ground or in a small cart, requiring manual secondary treatment, which is not only time-consuming and labor-intensive, but also increases costs. However, our decontamination machine does not require artificial secondary treatment, because our dirt will flow out from the cooling water outlet with the flushing water, and go where it should go, which is highly automated and reduces costs.

The fit between the device and the system: After the work of the grid type decontamination machine is completed, a large amount of system wastewater used up by the heating system will be left, which is a trouble for the sewage source heat pump system, and it is also a problem for water resources. A colossal waste. The root cause of this situation is that the fit between the grid type decontamination machine and the sewage source heat pump system is low.
