压电式超声雾化降尘系统设计及其试验研究
Design and Experimental Study of Piezoelectric Ultrasonic Atomizing Dust Removal System
摘要
Abstract
Conveying materials through a conveyor belt is the main way of bulk material industrial transportation,and the dust control in the transportation process in the bulk material transportation urgently needs to be solved.Currently,more methods for atomized dust removalare applied.In order to enhance the atomization and dust removal effects,this paper designs a 30 kHz horn piezoelectric ultrasonic atomization device and its supporting atomized dust removal system and then uses the single factor test to study the effects of process parameters such as inlet water flow,wind speed,dust type,particle diameter and nozzle installation angle on atomization and dust removal efficiency.The results show that when the inlet water flow is 30 L/h,the coal dust removal efficiency is 75.9%and thatwhen the wind speed is 2.1 m/s,the removal efficiency is 61.1%.Compared with pulverized coal and sand,loess has higher dust removal efficiency.The pulverized coal dust removal efficiency of the nozzle increases to 73.9%,ranging between 107~180 μm.When the nozzle installation angle is 0,the coal dust removal efficiency is the highest,being 81%.关键词
