AI Technical Summary

Technical Problem

Existing exhaust gas treatment devices do not comprehensively treat harmful substances in exhaust gas, and the separation of particulate matter from gas is incomplete. After long-term treatment, particulate matter will stick to the filter screen, affecting the treatment efficiency.

Method used

It adopts a multi-layer filter structure, combining activated carbon adsorption and alkaline spraying. Activated carbon adsorbs harmful gases and fine particles, while alkaline solution reacts with acidic gases to generate harmless salts. At the same time, the filter screen is automatically cleaned by vibration through cam and gear transmission.

Benefits of technology

It achieves multiple purification of exhaust gas, improves purification efficiency, reduces manual maintenance costs, and keeps the treatment tank clean.
