The gas collecting hood is a collection device for the pollution source of the flue gas purification system. It can introduce dust and gas pollution sources into the purification system while preventing them from spreading to the production workshop and the atmosphere and causing pollution. Its performance has a direct impact on the technical and economic indicators of the purification system. Due to the difference in the structure of the pollution source equipment and the production and operation process, the forms of the gas collecting hood are various.
(1) According to the airflow mode of the hood, it is divided into: suction type and blowing type;
(2) According to the relative position and scope of the air collecting hood and the pollution source, the suction air collecting hood is divided into: airtight hood, exhaust cabinet, external air collecting hood, receiving air collecting hood, etc.
The working principle of blow-suction hood and air curtain blow-suction hood
When the distance between the external suction hood and the pollution source is large, an suction port can be set on the opposite side of the external suction hood to form a layer of air curtain to prevent pollutants from dissipating and at the same time induce the pollution airflow to flow to the exhaust hood. .
Features: Air curtain is used to suppress the diffusion of pollutants, with small air volume, strong anti-interference ability, without affecting the process operation, and good results
