Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection machinery, and particularly relates to a highly efficient electrostatic dust absorption device with corrosion resistance. Background Art

[0002] When a chemical factory processes products, a large amount of dust is generated. The dust contains a large amount of corrosive impurities. The dust will pollute the atmospheric environment. In order to prevent the dust from polluting the atmosphere, when the dust is discharged, prevention and control equipment in the advanced environmental protection industry needs to be used. In the highly efficient electrostatic dust absorption device of the prevention and control equipment, the inside of the dust absorption device has corrosion resistance. The dust absorption device absorbs the dust into the device interior, the dust is purified inside the device, and the purified dust is discharged. Finally, the purified impurities are collected and cleaned up.

At the same time, when discharging impurities, the staff needs to adjust the collecting item and then control the operation valve to control the switch, and the operation is relatively cumbersome. Summary of the Invention
