| Abstract: | This paper introduces the propagation and frequency spectrum characteristics of the jet noise of the air box pulse bag dust collector,analyzes the causes of the jet noise in the clean air box and through the nozzle and the valve body,and puts forward the solutions.By adopting the measures of sound insulation board and ultra-fine glass wool sound absorption,the noise value is significantly reduced and the noise emission requirements are met. |
