[0040] Four groups of electric valves, three groups of water pumps, two groups of air volume control valves, and pressure sensor 431 are all connected to the equipment program signal.

[0041] Dust removal operation:

[0042] When the staff needs to use the environmental protection equipment for production operation, the staff first uses the lifting equipment to move the dust removal box 2 to the side of the environmental protection equipment, and then connects the air inlet pipe 21 to the workshop air supply device, and the first air outlet pipe 22 is connected to the environmental protection equipment. Then the staff turns on the workshop power supply, and the dust removal box 2 is started, the equipment program is started, and the staff controls the air intake volume according to different production volumes. The equipment program sets the production volume to M1, M2, and M3, M1 is the minimum value, and M3 is the maximum value. It can be adjusted according to specific needs. When the production volume is M1, the equipment program It is determined that the production volume of the environmental protection equipment is low and there is no need to use the maximum air intake volume. The equipment program controls the two sets of second air volume control valves 421 to open, the two sets of first air volume control valves 411 to be closed, and the first electric valve 231 to be closed. The external air enters the dust removal box 2 through the air inlet pipe 21, and then enters the two sets of second dust removal pipes 42 through the dust removal chamber 211. At this time, the dust removal filter 43 performs dust removal operation on the inhaled air. The dust-removed air will be transported backward to the air outlet chamber 212, and then output from the first air outlet pipe 22 to the external environmental protection equipment;

[0043] When the production volume is M2, the equipment program determines that the environmental protection equipment is in normal production volume and needs to increase the air intake volume. The equipment program controls the two sets of second air volume control valves 421 to open, the two sets of first air volume control valves 411 to open, and the first electric valve 231 to be in a closed state. External air enters the dust removal box 2 through the air inlet pipe 21, and then enters the two sets of first dust removal pipes 41 and the two sets of second dust removal pipes 42 through the dust removal chamber 211. At this time, the dust removal filter 43 performs dust removal operation on the inhaled air, and the dust-removed air is transported backward to the air outlet chamber 212, and then output from the first air outlet pipe 22 to the external environmental protection equipment;

[0044] When the production volume is M3, the equipment program determines that the environmental protection equipment is in high production volume and needs to increase the air intake volume. The equipment program controls the two sets of second air volume control valves 421 to open, the two sets of first air volume control valves 411 to open, and the first electric valve 231 to be closed. The external air enters the dust removal box 2 through the air inlet pipe 21, and then enters the two sets of first dust removal pipes 41 and the two sets of second dust removal pipes 42 through the dust removal chamber 211. At this time, the dust removal filter 43 performs dust removal operation on the inhaled air, and the dust-removed air will be transported backward to the air outlet chamber 212, and then output from the first air outlet pipe 22 to the external ring In the protection equipment, during the above operation, the equipment program controls the two groups of second water pumps 32 to open, the two groups of third electric valves 323 to open, the two groups of third water pumps 33 and the two groups of fourth electric valves 333 to be in a closed state, and the two groups of second water pumps 32 pump the dust removal water in the water tank 31 into the two groups of first water pipes 321, and then transport it to the two groups of first dust removal nozzles 322 and spray it outward in the form of water mist. The sprayed water mist will float downward in the dust removal chamber 211, thereby improving the dust removal effect on the incoming air, and avoiding the clogging of the dust removal filter 43 due to turbid air at a high air intake volume, which affects the production efficiency of the environmental protection equipment;

[0045] Through the coordinated use of four sets of air volume control valves, two sets of second water pumps 32 and equipment programs, the air intake volume can be changed according to the different outputs of the environmental protection equipment, and the inhaled air can be dusted. When the output is low, only the dust filter 43 on the two sets of second dust removal pipes 42 is used for air dust removal, which ensures the dust removal effect while reducing energy consumption in the production process, achieving the effect of energy saving and emission reduction, and at the same time reducing the production cost of the factory. When the output is high, four sets of dust removal pipes are used for air dust removal, and only the water mist sprayed by the two sets of first dust removal nozzles 322 is used to perform preliminary dust removal on the inhaled air, and the water mist is dispersed in the dust removal chamber 211 by its own weight, reducing the waste of water resources in the production process and improving the dust removal efficiency. It is avoided that the dust and sand in the air clog the dust filter 43, and the service life of the dust filter 43 is increased. There is no need for frequent replacement and cleaning, which reduces the burden on the staff.

[0046] Spray dust removal operation:

[0047] During the above operation, the equipment program controls the spray dust removal operation. The equipment program detects the value of the pressure sensor 431 and compares it with the set value. The equipment program sets the pressure values ​​to X1, X2, and X3, where X1 is the minimum value and X3 is the maximum value. The pressure values ​​can be adjusted according to specific needs. When the equipment program detects that the value of any group of pressure sensors 431 is X1, the equipment program determines that there is little dust and sand adsorbed on the dust removal filter 43, and there is no need to perform the spray dust removal operation, and the equipment program has no operation.

[0048] When the equipment program detects that the value of any group of pressure sensors 431 is X2, the equipment program determines that dust and sand are adsorbed on the dust filter 43, and it is necessary to perform a spray dust removal operation on the dust removal chamber 211 to avoid that the turbid air affects the dust removal effect. The equipment program controls the two groups of second water pumps 32 to open, the two groups of third electric valves 323 to open, the two groups of third water pumps 33 and the two groups of fourth electric valves 333 are in a closed state, and the two groups of second water pumps 32 pump the dust removal water in the water tank 31 into the two groups of first water pipes 321, and then transport it to the two groups of first dust removal nozzles 322 and spray it outward in the form of water mist. The sprayed water mist will float downward in the dust removal chamber 211, thereby improving the dust removal effect on the incoming air and avoiding the turbid air at high air intake volume causing the dust filter 43 to be blocked, affecting the production efficiency of the environmental protection equipment;

[0049] When the device program detects that the value of any group of pressure sensors 431 is X3, the device program determines that there is a lot of dust and sand on the dust filter 43, and the spray dust removal effect needs to be improved to avoid the dust filter 43 being blocked and affecting the air intake effect. The device program controls the two groups of second water pumps 32 and the two groups of third water pumps 33 to open, the two groups of third electric valves 323 and the two groups of fourth electric valves 333 to open, the two groups of third water pumps 33 and the two groups of fourth electric valves 333 are in a closed state, and the two groups of second water pumps 32 and the two groups of third water pumps 33 pump the dust removal water in the water tank 31 into the two groups of first water pipes 321 and the two groups of second water pipes 331, and then transport it to the two groups of first dust removal nozzles 322 and the two groups of second dust removal nozzles 323 and the two groups of second dust removal nozzles 322. The dust nozzle 332 sprays outward in the form of water mist, and the sprayed water mist will float downward in the dust removal chamber 211, thereby improving the dust removal effect on the incoming air, and avoiding the clogging of the dust removal filter 43 caused by turbid air at a high air intake volume, which affects the production efficiency of the environmental protection equipment. While performing the above operations, the equipment program controls the water tank 31 to spray water from the humidifying nozzle 313 to the inside of the workshop in the form of water mist, and the equipment program controls the first electric valve 231 to open, so as to transport the clean air after dust removal to the inside of the workshop, increase the air flow rate in the workshop, make the air in the workshop circulate, discharge the turbid air in the workshop to the outside, and cooperate with the humidifying nozzle 313 to spray the air in the workshop for dust removal;

[0050] By using the pressure sensor 431, the second water pump 32, the third water pump 33 in conjunction with the equipment program, it is possible to determine whether the dust filter 43 is clogged with dust according to different pressure values, and to determine the air turbidity according to different pressure values ​​to change the spray dust removal method. When the pressure value is small and the air turbidity is low, it is only necessary to filter and remove dust through the dust filter 43 without using a spray operation, thereby reducing energy consumption during the dust removal process and achieving the effect of energy conservation and emission reduction. When the pressure value is high and the air turbidity is high, four groups of dust removal nozzles are used in conjunction with the dust filter 43 to spray and remove dust, thereby reducing dust removal dead corners, improving dust removal efficiency, and avoiding clogging of the dust filter 43 to affect the air intake effect. By using the first electric valve 231 in conjunction with the humidifying nozzle 313, the clean air after dust removal can be diverted for ventilation and dust removal operations in the workshop, thereby avoiding the turbid air in the workshop affecting the air intake efficiency of the dust removal box 2, and at the same time avoiding the staff from inhaling turbid air for a long time, thereby improving the production environment in the workshop.

[0051] Wastewater Recycling Operations:

[0052] During the above operation, the equipment program controls the wastewater recovery operation. The equipment program sets the back timing time to T1, which can be adjusted according to specific needs. The recovery time is T2, which can be adjusted according to specific needs. When the above production operation is performed, the equipment program starts timing. When T1 time is up, the equipment program controls the first water pump 312 to start and the second electric valve 314 to open. The first water pump 312 sucks the dust removal wastewater accumulated at the bottom of the dust removal chamber 211 into the recovery water pipe 311, and then transports it to the built-in filter structure of the water tank 31 for filtration. The filtered water will flow into the water tank 31 again. The recovery time is T2. When the recovery time T2 is up, the equipment program controls the first water pump 312 and the second electric valve 314 to close. At this time, the equipment program repeats the above timing operation.

[0053] By using the first water pump 312, the second electric valve 314 and the equipment program in coordination, the wastewater recovery operation can be automatically performed on the dust removal box 2 after it has been running for a specified time, and the recovered dust removal wastewater can be secondary filtered and used again for dust removal operations, thereby reducing resource waste in the dust removal process and reducing factory costs.
