Project Name: Xiangdang electric

Project address: Qianqiao, Fengxian District, Shanghai

Discharge condition: forced exhaust

Pollution source: waste gas from vacuum impregnation of insulating paint, waste gas from drying insulating paint

Pollution Name: resin dust (paint mist), benzene, toluene, xylene, non methane total hydrocarbon

Technical scheme of purification treatment:

The exhaust gas centralized collection and purification system of vacuum impregnated insulating paint furnace and insulating paint drying room, combined with the actual working conditions of the site, needs to be pre filtered by mechanical physical filter particles.

For the control method of volatile organic pollutants (VOCs), low temperature plasma organic waste gas cracking + UV photodegradation organic waste gas decomposition oxidation reduction composite technology was selected to introduce foreign mature laboratory technology to Shanghai Fengjing, and through the cooperation between Shanghai Fudan and environmental protection technology experts, the real low temperature plasma + UV photodegradation oxidation technology was independently developed, which was widely used in large air volume, medium and low air volume. The concentration VOCs waste gas purification treatment has the advantages of high purification efficiency, low operation cost and no secondary pollution.
