1. Dust pollution when the spray gun of the powder spraying equipment is working.
Remediation method: Increase the recovery power of the fan by 15% on the premise of not affecting the powder spraying work, and use a water mist mixing device at the discharge end to vigorously recover the fine particles in the powder, and then discharge it to the atmosphere after testing to meet the standard. go in. But inevitably make users increase the cost.
Second, the oven plus source pollution is mainly the pollution of coal heating.
Remediation method: use natural gas or liquefied gas where conditions permit, and use biological particle furnace for heating where powder spraying equipment does not have conditions, but need to install water filtration equipment.
3. The main pollution sources of the painting production line are: VOC, formaldehyde, xylene, alcohol ether and other harmful volatile particles pollute the air.
Treatment method: After the powder spraying equipment spray booth is installed with water curtain and plasma photo-oxygen waste gas treatment equipment, it will be discharged outdoors after reaching the standard.
Fourth, the pre-treatment of industrial metal products before spraying should be mostly shot blasting, and a shot blasting treatment room should be set up and dust filtering equipment should be installed and discharged into the outdoors after reaching the standard.
