含塵氣體由進(jìn)風(fēng)口進(jìn)入除塵器箱體內(nèi)，細(xì)小塵粒由于布袋的多種效應(yīng)作用，被滯阻在布袋外壁。凈化后的氣體通過(guò)布袋上箱體出風(fēng)口排出。隨著使用時(shí)間的增長(zhǎng)，布袋表面吸附的粉塵增多，布袋的透氣性減弱，使除塵器阻力不斷增大。

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.

為除塵器的阻力控制在限定的范圍之內(nèi)，由脈沖控制儀發(fā)出信號(hào)，循序打開(kāi)電磁脈沖閥，使氣包內(nèi)的壓縮空氣由噴吹管各噴孔噴射到對(duì)應(yīng)的文氏管（稱為一次風(fēng)〉﹐并在高速氣流通過(guò)文氏管時(shí)誘導(dǎo)數(shù)倍于一次風(fēng)的周?chē)諝猓ǚQ為二次風(fēng)〉進(jìn)入濾筒，造成布袋間急劇膨脹，由于反向脈沖氣流的沖擊作用很快消失，布袋又急劇收縮，這樣使積附在布袋外壁上的粉塵被，落下的灰塵進(jìn)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.

倉(cāng)頂脈沖布袋式除塵器是利用布袋過(guò)濾原理將氣灰分離，向外排除乏氣，使容器內(nèi)保持常壓的裝置。它適宜布置在各種粉料貯存庫(kù)的頂部，特別適合用于氣力輸送工藝中的受料倉(cāng)頂部。由于清灰技術(shù)，氣布比大幅度提高，故具有處理風(fēng)里大、占地面積小、凈化、工作、結(jié)構(gòu)簡(jiǎn)單、維修里小等特點(diǎn)。除塵效率可以到以上。是一種成熟的比較的除塵設(shè)備。倉(cāng)頂除塵器:是一種用在料倉(cāng)頂部的除塵設(shè)備。倉(cāng)頂除塵器主要應(yīng)用于采礦、冶金建材、機(jī)械﹑化工﹑糧食加工等工礦企業(yè)料倉(cāng)使用。并廣泛用于過(guò)濾氣體中細(xì)小的，非纖維性的干燥粉塵或在工藝流程中回收干燥粉料的一種除塵設(shè)備。

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.

通過(guò)布袋將料倉(cāng)內(nèi)漂浮的粉塵顆粒隔離開(kāi)，并將干凈的空氣排放到大氣中，以此來(lái)保護(hù)環(huán)境。

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