Research on Dust-removal Mechanism and Application of Hydraulic Dust Collector

Theoretic analysis was made on dust removal mechanism of hydraulic wet dust collector and tests were conducted on its performance parameters including air quantity, negative pressure, noise, dewatering efficiency and dust collecting efficiency. The results showed that the maximum air quantity of the hydraulic dust collector reaches 180 m3/min, negative pressure is up to 810 Pa, noise is about 85 dB(A), dewatering efficiency is up to 96.5% and dust collecting efficiency reaches 98.22%, all performance parameters achieved the anticipated results. The field application showed that the hydraulic dust collector is featured by step-less speed regulation and easy mounting on machine, and after the use of this dust collector, the dust concentration at the place 5m away to the heading face reduced by 91.6%, better dust collecting effectiveness was obtained.
