含尘气体由进风口进入除尘器箱体内，细小尘粒由于布袋的多种效应作用，被滞阻在布袋外壁。净化后的气体通过布袋上箱体出风口排出。随着使用时间的增长，布袋表面吸附的粉尘增多，布袋的透气性减弱，使除尘器阻力不断增大。

Dust containing gas enters the dust collector box through the air inlet, and small dust particles are trapped on the outer wall of the bag due to various effects of the bag. The purified gas is discharged through the air outlet of the box on the cloth bag. As the usage time increases, the amount of dust adsorbed on the surface of the cloth bag increases, the breathability of the cloth bag weakens, and the resistance of the dust collector continues to increase.

为除尘器的阻力控制在限定的范围之内，由脉冲控制仪发出信号，循序打开电磁脉冲阀，使气包内的压缩空气由喷吹管各喷孔喷射到对应的文氏管（称为一次风〉﹐并在高速气流通过文氏管时诱导数倍于一次风的周围空气（称为二次风〉进入滤筒，造成布袋间急剧膨胀，由于反向脉冲气流的冲击作用很快消失，布袋又急剧收缩，这样使积附在布袋外壁上的粉尘被，落下的灰尘进入灰斗。

To control the resistance of the dust collector within a limited range, a pulse controller sends a signal and sequentially opens the electromagnetic pulse valve, causing the compressed air in the air bag to be sprayed from each nozzle of the blowing pipe to the corresponding Venturi tube (called primary air). When the high-speed airflow passes through the Venturi tube, it induces the surrounding air (called secondary air) with a derivative of twice the primary air to enter the filter cartridge, causing rapid expansion between the cloth bags. Due to the rapid disappearance of the impact of the reverse pulse airflow, the cloth bags contract sharply again, causing the dust accumulated on the outer wall of the cloth bags to be trapped and the dust falling into the ash hopper.

仓顶脉冲布袋式除尘器是利用布袋过滤原理将气灰分离，向外排除乏气，使容器内保持常压的装置。它适宜布置在各种粉料贮存库的顶部，特别适合用于气力输送工艺中的受料仓顶部。由于清灰技术，气布比大幅度提高，故具有处理风里大、占地面积小、净化、工作、结构简单、维修里小等特点。除尘效率可以到以上。是一种成熟的比较的除尘设备。仓顶除尘器:是一种用在料仓顶部的除尘设备。仓顶除尘器主要应用于采矿、冶金建材、机械﹑化工﹑粮食加工等工矿企业料仓使用。并广泛用于过滤气体中细小的，非纤维性的干燥粉尘或在工艺流程中回收干燥粉料的一种除尘设备。

The pulse bag filter on the top of the warehouse is a device that uses the principle of bag filtration to separate gas and ash, expel exhaust gas outward, and maintain atmospheric pressure inside the container. It is suitable for placement on the top of various powder storage warehouses, especially suitable for use on the top of the receiving bin in pneumatic conveying processes. Due to the dust removal technology, the air to cloth ratio has been significantly improved, which has the characteristics of large processing air volume, small footprint, purification, simple structure, and small maintenance space. The dust removal efficiency can reach above. It is a mature and comparative dust removal equipment. Top dust collector: It is a dust removal equipment used at the top of the silo. The dust collector on the top of the warehouse is mainly used in mining, metallurgical building materials, machinery, chemical, grain processing and other industrial and mining enterprises for material storage. And it is widely used as a dust removal equipment for filtering small, non fibrous dry dust in gas or recovering dry powder in process flow.

通过布袋将料仓内漂浮的粉尘颗粒隔离开，并将干净的空气排放到大气中，以此来保护环境。

Separate the floating dust particles in the silo through cloth bags and discharge clean air into the atmosphere to protect the environment.
