[0017] like Figure 1-5As shown, a dust collection device for an aluminum powder production workshop includes a production workshop 1. Several vertically arranged dust collection pipes 2 are installed on the ceiling of the production workshop 1, extending upwards to the outside of the ceiling 20. The outlets of the dust collection pipes 2 are connected to horizontal pipes 6, which are connected to a dust removal device and a purification device. The purification device is connected to a fan 28. The dust removal device includes a dust collection box 7, inside which are vertically arranged partitions 8. The bottom of the partitions 8 is fixedly connected to the top of the bottom plate of the dust collection box 7. A ventilation channel 9 is provided between the top of the partitions 8 and the top plate of the dust collection box 7. A water tank 10 is installed on the top of the dust collection box 7, and a vertical pipe 11 is connected to the bottom of the water tank 10, extending into the dust collection box 7. A solenoid valve is installed on the top. The bottom of the vertical pipe 11 is connected to a horizontal water pipe 17. Several connecting pipes 12 are connected to both sides of the horizontal water pipe 17 along its length. The connecting pipes 12 are set perpendicular to the horizontal water pipe 17. The bottom of the connecting pipes 12 is connected to a nozzle 13. Specifically, when the fan 28 is started, the dust suction pipe 2 sucks the dust floating in the air in the workshop into the dust suction pipe 2. Finally, all of it is sucked into the dust collection box 7 through the horizontal pipe 6. The solenoid valve is opened, and the water in the water tank 10 is sprayed out through the nozzle 13 to spray and suppress the dust. The dust will fall to the bottom of the dust collection box 7. Some of the dust that has not been wetted will enter the air purification device through the ventilation duct 9, where it will be purified again before being discharged into the atmosphere.

[0018] A filter assembly is detachably installed at the bottom of the air inlet of the vacuum pipe 2. The filter assembly includes a mounting ring 4, a filter screen 5 installed in the through hole of the mounting ring 4, and connecting plates 1-3 symmetrically arranged on both sides of the outer side of the mounting ring 4. Connecting plates 2-14 are symmetrically arranged on both sides of the air inlet of the vacuum pipe 2. Bolts 15 are fixedly connected inside the connecting plates 2-14, passing through the connecting plates 1-3, and nuts 16 are installed on the bolts 15. Specifically, the filter screen 5 performs initial filtration of the sucked-in dust and filters out larger impurities to prevent them from entering and clogging the vacuum pipe 2. The filter screen 5 can be replaced by loosening the nuts 16 and removing the mounting ring 4.

[0019] The air purification device includes a purification housing 19, within which a top plate 20 and a bottom plate 21 are installed. A dust collection pipe 22 connects the top plate 20 and the bottom plate 21. The dust collection pipe 22 has open ends, passing through the top plate 20 and the bottom plate 21 respectively. A corona electrode 23 is installed inside the dust collection pipe 22, and a corona electrode connecting plate 24 is connected to the top of the corona electrode 23. A high-voltage generator 25 is connected to the corona electrode connecting plate 24 and is installed on the top of the outside of the purification housing 19. Specifically, when dust enters the purification housing 19, the corona electrode 23 charges the incoming dust, which is then adsorbed onto the dust collection pipe 22. Clean air then...

[0020] The corona electrode 23 has multiple branches 26 evenly distributed along its length; increasing the area of ​​the corona electrode 23 allows more dust particles to carry an electric charge.

[0021] The upper part of the air purification housing 19 is connected to a connecting pipe 27, which is located above the top plate 20. The connecting pipe 27 is connected to a fan 28, and the fan 28 is connected to an air outlet pipe 29. Specifically, dust enters the dust collection pipe 22 and is charged and adsorbed on the dust collection pipe 22. Clean air exits from the top of the dust collection pipe, passes through the connecting pipe 27, and is finally discharged into the atmosphere from the air outlet pipe 29.

[0022] A connecting pipe 30 is provided between the clean air housing 19 and the dust collection box 7, and the connecting pipe 30 is located below the bottom plate 21.

[0023] The bottom of the dust collector 7 is connected to a drain pipe 32; the drain pipe 32 can periodically discharge the wastewater in the dust collector 7.
