Roots Blower Selection and Applications

1. Pneumatic ash conveying

coal-fired power plants can produce a large amount of fly ash in the production process. Firstly, the electrostatic precipitator is used to collect it into the ash hopper; Then put the coal ash into the transmission pipeline. Finally, use the compressed air discharged by the roots blower to make the coal ash flow into the ash silo; The following are the performance parameters for Roots blower.

Pressure rise: 68.6kpa; Airflow of 5 ~ 16m³/min.

Another common method is negative pressure suction at the end of the ash conveying system to make the fly ash fall into the ash silo

2.Polymer powder conveying

In the process of polymer production, we usually use nitrogen to transport granular raw materials such as polyethylene and polypropylene. The purpose of using nitrogen is to prevent the explosion of polymer raw materials with air and flammable and volatile media. In order to reuse nitrogen, the conveying system is a closed-loop. After filtration, The delivered gas will return to the blower for recycling.
