除尘原理：   含尘气体经由袋式集尘机入口进入，经由分风档板废气粉尘均分布在每支滤袋上，控制系统可由差压或时间控制，高压清洗空气经控制系统控制，把电磁阀打开后，高压清洗空气脉冲喷射，由文氏管扩散而下，将滤袋外面附著的粉尘打下来，粉尘落下至集尘桶再经由螺旋输送机及旋转供料器排出机外。THEORY OF DUST ELIMINATION PROCESS:the dust air emters through the dust levels air inlet,then it goes through thesistribution baffle where the dust exhaust air is spread evenly among the filter bags.the pulse valve is then turned on by either a timecontrolled system or a defferential air pressuresystem.next,pre-ssaxized clean air is jet pulsed all theway down thefilter bags.allof the dust in the filter bags falls down and is collected,the screw conveyerand therotarythen push thecollected dust out of the jet pulse dust collector.
