Experimental study on frequency-conversion speed-regulation performance of mine-used wet scrubber

Abstract

In view of problem that continuous advancing of excavation working face results in decreasing of specific value of pressed and exhausted air volume in excavation roadway, and impacts dust control and collection effects of wet scrubber, frequency-conversion speed-regulation principle was introduced, and relations between air volume and frequency, air volume and power, dust collection efficiency and frequency of wet scrubber were obtained through testing, which provided a basis for air volume control and determination of frequency control range of wet scrubber.
