脈沖除塵器是在袋式除塵器的基礎(chǔ)上改進的新型脈沖除塵器，綜合了分室反吹各種脈沖噴吹除塵器的優(yōu)點，克服了分室清灰強度不夠，進出風分布不均等缺點，擴大了應用范圍。

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.

脈沖除塵器是當含塵氣體由進風口進入除塵器，碰到進出風口中間的斜板及擋板，氣流便轉(zhuǎn)向流入灰斗，同時氣流速度放慢，由于慣性作用，使氣體中粗顆粒粉塵直接流入灰斗。起預收塵的作用，進入灰斗的氣流隨后折而向上通過內(nèi)部裝有金屬骨架的濾袋粉塵被捕集在濾袋的外表面，凈化后的氣體進入濾袋室上部清潔室，匯集到出風口排出，含塵氣體通過濾袋凈化的過程中，隨著時間的增加而積附在濾袋上的粉塵越來越多，增加濾袋阻力，致使處理風量逐漸減少，為正常工作，要控制阻力在一定范圍內(nèi)（140--170毫米水柱），一旦超過范圍必須對濾袋進行清灰，清灰時由脈沖控制儀順序觸發(fā)各控制閥開啟脈沖閥，氣包內(nèi)的壓縮空氣由噴吹管各孔經(jīng)文氏管噴射到各相應的濾袋內(nèi)，濾袋瞬間急劇膨脹，使積附在濾袋表面的粉塵脫落，濾袋恢復初始狀態(tài)。清下粉塵落入灰斗，經(jīng)排灰系統(tǒng)排出機體。由此使積附在濾袋上的粉塵周期地脈沖噴吹清灰，使凈化氣體正常通過，保證除塵系統(tǒng)運行。

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.

1、采用分室停風脈沖噴吹清灰技術(shù)，克服了常規(guī)脈沖除塵器和分室反吹除塵器的缺點，清灰能力強，除塵效率高，排放濃度低，漏風率小，能耗少，鋼耗少，占地面積少，運行穩(wěn)定可靠，經(jīng)濟效益好。適用于冶金、建材、水泥、機械、化工、電力、輕工行業(yè)的含塵氣體的凈化與物料的回收。

1. The use of chamber stop pulse jet cleaning technology overcomes the shortcomings of conventional pulse dust collectors and chamber backflow dust collectors. It has strong cleaning ability, high dust removal efficiency, low emission concentration, low air leakage rate, low energy consumption, low steel consumption, small footprint, stable and reliable operation, and good economic benefits. 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、由于采用分室停風脈沖噴吹清灰，噴吹一次就可達到徹底清灰的目的，所以清灰周期延長，降低了清灰能耗，壓氣耗量可大為降低。同時濾袋與脈沖閥的疲勞程度也相應減低，從而成倍地提高濾袋與閥片的壽命。

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.

3、檢修換袋可在不停系統(tǒng)風機，系統(tǒng)正常運行條件下分室進行。濾袋袋口采用彈性漲圈，密封性能好，牢固可靠。濾袋龍骨采用多角形，減少了袋與龍骨的磨擦，延長了袋的壽命，又便于卸袋。
