Description

Technical Field

[0001] This utility model relates to an integrated filtration and purification machine, and more particularly to an integrated multi-stage filtration and purification machine for industrial waste gas. Background Technology

[0002] Patent publication number CN219984052U discloses a multi-stage filtration device for purifying chemical production waste gas. The device includes a filter box connected to a water inlet pipe. A groove is located at the bottom of the inner wall of the filter box. A stirring structure is fixedly connected to the motor output. By using the stirring mechanism and water inlet pipe, water is injected into the filter box before purification. Waste gas is then introduced into the filter box through the air inlet pipe and a vacuum pump. The motor drives a rotating rod, which in turn drives a turntable through the meshing of a first and second bevel gear. This rotation of the stirring rod stirs the filtrate, reducing particulate matter in the waste gas and improving purification capacity. An exhaust channel and activated carbon are also included. After purification by the stirring structure, the waste gas enters the exhaust channel, where the activated carbon adsorbs any remaining particulate matter, further enhancing purification capacity and efficiency. While this patent achieves waste gas purification and filtration, the device's simple filtration followed by direct discharge can easily cause air pollution.

[0023] When workers need to perform multi-stage filtration and purification of industrial waste gas, they can connect the waste gas pipe of the waste gas equipment to the connecting pipe 3. The waste gas will enter the V-shaped paper dry filter 2 and the filter box 4 through the connecting pipe 3. The V-shaped paper dry filter 2 can filter the particles in the waste gas. The filtered gas will be discharged into the gas collecting cylinder 6. The activated carbon filter plate 8 can filter the gas again. The filtered gas in the gas collecting cylinder 6 will be discharged from the conveying pipe 7. When workers need to replace the activated carbon filter plate 8, they can pull the magnetic stabilizing block 10 outward. The magnetic stabilizing block 10 will stop fixing the clamping rod 9. Then, the workers can remove the activated carbon filter plate 8 from the clamping rod 9. After the activated carbon filter plate 8 is removed and replaced by the staff, the staff can push the magnetic stabilizing block 10 from the inside. The magnetic stabilizing block 10 will then re-fix the locking rod 9, thus completing the rapid filtration of exhaust gas particles. To further reduce pollutants in the exhaust gas, the gas from the conveying pipe 7 will enter the spray box 1702. After the smoke sensor 18 detects the gas entering, it will control the controller 17 to open. The sodium hydroxide solution in the storage box 12 will be sprayed into the spray box 1702 through the spray pipe 1701 and the nozzle 1801. The sodium hydroxide solution can remove acidic pollutants in the exhaust gas. The gas after pollutant removal will then flow from the... The exhaust gas is discharged from the top of the spray box 1702, thus completing the rapid purification of the waste gas. When the sodium hydroxide solution in the storage box 12 is insufficient, the operator can pull out the sealing ring 14. At this time, the operator can pour an appropriate amount of sodium hydroxide solution into the filling tube 13. The sodium hydroxide solution in the filling tube 13 will slide into the storage box 12. Then, the operator can put the sealing ring 14 back on the filling tube 13. The connecting seat 15 provides support. The gas discharged from the spray box 1702 will be forced into the UV photo-oxidation purifier 16. The UV photo-oxidation purifier 16 uses a specially designed high-energy, high-ozone UV ultraviolet light beam to irradiate the odorous gas, breaking down the odorous gas and thus reducing the odor of the gas. The gas produced by the UV photo-oxidation purifier 16 after decomposition is squeezed into the collection hood 19, and the gas in the collection hood 19 is discharged from the exhaust pipe 20. The connecting column 21 provides support. The operator can turn on the suction fan 22, which will draw the gas out of the exhaust pipe 20. When the operator no longer needs to draw the gas out of the exhaust pipe 20, the operator can turn off the suction fan 22. When there is a lot of waste liquid in the spray box 1702, the operator can open the valve 24, and the waste liquid in the spray box 1702 will be discharged from the waste liquid pipe 23. When the operator no longer needs to discharge the waste liquid in the spray box 1702, the operator can close the valve 24.
