Hot metal spraying dust pollution is not a matter of tolerance and must be taken seriously!

       / Thermal metal spray dust control method /



(1) Source control



Capture and control sources of thermal spray dust and fumes, including the use of various types of hoods to extract contaminants at or near the source to protect workers and prevent fumes from migrating to other facilities.



The source is the most efficient to capture and requires the least energy and initial investment to complete. Source capture can be achieved using smoke extraction arms or a local fixed hood.



(2) Ventilation and isolation



The containment enclosure isolates the thermal spray process from the rest of the equipment and protects the contained area. Safety hoods are often not practical for hoods close to the spray area, but the process can be isolated from the rest of the plant. An example is a booth or zoned area where ventilation is used to control and collect process dust, fumes and gases.



(3) Dust removal equipment



In the powder coating process, especially in the thermal metal coating system, a powder coating recovery device and a dust-filtering dust removal system must be installed. Whether it is the air discharged to the atmosphere or the air that is recycled, it should meet the national environmental protection emission standards. , is currently the most effective way to control dust.
