脉冲除尘器是在袋式除尘器的基础上改进的新型脉冲除尘器，综合了分室反吹各种脉冲喷吹除尘器的优点，克服了分室清灰强度不够，进出风分布不均等缺点，扩大了应用范围。

Pulse dust collector is a new type of high-efficiency pulse dust collector that is improved on the basis of bag dust collector. It combines the advantages of various pulse jet dust collectors with chamber backflow, overcomes the shortcomings of insufficient cleaning intensity and uneven distribution of inlet and outlet air in the chamber, and expands the application range.

脉冲除尘器是当含尘气体由进风口进入除尘器，碰到进出风口中间的斜板及挡板，气流便转向流入灰斗，同时气流速度放慢，由于惯性作用，使气体中粗颗粒粉尘直接流入灰斗。起预收尘的作用，进入灰斗的气流随后折而向上通过内部装有金属骨架的滤袋粉尘被捕集在滤袋的外表面，净化后的气体进入滤袋室上部清洁室，汇集到出风口排出，含尘气体通过滤袋净化的过程中，随着时间的增加而积附在滤袋上的粉尘越来越多，增加滤袋阻力，致使处理风量逐渐减少，为正常工作，要控制阻力在一定范围内（140--170毫米水柱），一旦超过范围必须对滤袋进行清灰，清灰时由脉冲控制仪顺序触发各控制阀开启脉冲阀，气包内的压缩空气由喷吹管各孔经文氏管喷射到各相应的滤袋内，滤袋瞬间急剧膨胀，使积附在滤袋表面的粉尘脱落，滤袋恢复初始状态。清下粉尘落入灰斗，经排灰系统排出机体。由此使积附在滤袋上的粉尘周期地脉冲喷吹清灰，使净化气体正常通过，保证除尘系统运行。

Pulse dust collector is a dust containing gas that enters the dust collector through the air inlet. When it first touches the inclined plate and baffle in the middle of the air inlet and outlet, the airflow turns to flow into the ash hopper. At the same time, the airflow speed slows down, and due to the inertia effect, the coarse dust particles in the gas directly flow into the ash hopper. As a pre dust collector, the airflow entering the ash hopper is then folded upwards and captured on the outer surface of the filter bag through the filter bag with a metal skeleton inside. The purified gas enters the upper cleaning room of the filter bag room and gathers at the air outlet for discharge. During the purification process of the dust containing gas through the filter bag, as time goes on, more and more dust accumulates on the filter bag, increasing the resistance of the filter bag and causing the processing air volume to gradually decrease. To ensure normal operation, the resistance must be controlled within a certain range (140-170 millimeters of water column). Once it exceeds the range, the filter bag must be cleaned. During the cleaning process, the pulse control instrument sequentially triggers each control valve to open the pulse valve, and the compressed air in the air bag is blown through the blowing pipe. Each hole is sprayed into the corresponding filter bag through a Venturi tube, and the filter bag rapidly expands, causing the dust accumulated on the surface of the filter bag to fall off, The filter bag is restored to its initial state. Dust is cleared and falls into the ash hopper, which is then discharged from the body through the ash discharge system. As a result, the dust accumulated on the filter bag is periodically pulse sprayed to clean the dust, allowing the purified gas to pass through normally and ensuring the operation of the dust removal system.

Suitable for the purification of dusty gases and material recovery in industries such as metallurgy, building materials, cement, machinery, chemical engineering, power, and light industry.

2、由于采用分室停风脉冲喷吹清灰，喷吹一次就可达到彻底清灰的目的，所以清灰周期延长，降低了清灰能耗，压气耗量可大为降低。同时滤袋与脉冲阀的疲劳程度也相应减低，从而成倍地提高滤袋与阀片的寿命。

2. Due to the use of chamber stop pulse jet cleaning, the purpose of thorough cleaning can be achieved by spraying once. Therefore, the cleaning cycle is extended, reducing the energy consumption of cleaning, and the compressed air consumption can be greatly reduced. At the same time, the fatigue level of the filter bag and pulse valve is correspondingly reduced, thereby doubling the service life of the filter bag and valve plate.
