AI Technical Summary

Technical Problem

When centrifugal fans transport gases with high humidity and corrosiveness, the volute and impeller are easily corroded, affecting the normal operation of the fan.

Method used

An exhaust gas fan was designed, including an inlet duct and a separation pipe. After the exhaust gas enters the separation pipe through the inlet duct, the liquid droplets are caused to settle by inertia and gravity, reducing the humidity of the gas. The gas is then separated from the liquid by a wire mesh, and the liquid droplets are collected in a collection box, reducing the accumulation of corrosive liquids inside the volute.

Benefits of technology

It effectively reduces the humidity of the exhaust gas entering the fan, reduces corrosion of the volute and impeller, ensures long-term stable operation of the fan, and improves air volume and energy saving through the dual-head design.

Abstract

This utility model provides an exhaust gas fan and an exhaust gas treatment system, relating to the field of exhaust gas treatment technology. The exhaust gas fan includes a fan body, an inlet duct, and a separation pipe. The fan body has an inlet end. The separation pipe includes a first pipe section and a second pipe section. The top end of the first pipe section is connected to the inlet duct, and the axis of the second pipe section intersects the axis of the first pipe section. One end of the second pipe section is connected to the middle of the first pipe section, and the other end is connected to the inlet end. A negative pressure is generated at the inlet end of the fan body, continuously drawing in exhaust gas through the inlet duct and the separation pipe. When the exhaust gas flows to the middle of the first pipe section, it is deflected into the second pipe section. Liquid droplets in the exhaust gas separate from the gas under the action of inertia and gravity, thereby reducing the humidity of the exhaust gas finally entering the inlet end. This improves the accumulation of corrosive liquids in the volute of the fan body, making the volute and impeller less susceptible to corrosion, which is beneficial for the long-term stable operation of the entire exhaust gas fan.
