Application Research on New Hydro-Style Turbulent Contact Scrubber

Abstract:

The new duster is used to remove the coal dust from the coal conveying system of thermal power plant. Many of plastic globules are filled into the duster. The water is sprayed from the upper of duster. The airflow of containing coal dust flows through the filler from bottom to top, and change to clean air. The application of the turbulent duster in the coal conveying system of the thermal power plant shows: the efficiency of dust collection is 99%. In particular, it can remove 67% of coal dust smaller than 5 microns. The duster adopts fully automatic control technology. The amount of water consumed is very low. It can be effectively used for coal conveying system of thermal power plant. After air purification with coal dust, the air quality meets the requirements of the health standard.
