The low pressure pulse long bag dust collector is a kind of pulse bag dust collector with advanced level, and is specially developed to meet the needs of large air flow purification on the basis of injection pulse dust removal technology. It not only has the characteristics of strong dust removal ability, high dust removal efficiency and low emission concentration of jet pulse dust collector, but also has the characteristics of stability and reliability, low gas consumption and small occupation area, and is especially suitable for dealing with flue gas of large air flow. The series of low pressure pulse bag dust collector has been applied all over the world, and has been widely popularized in China for flue gas purification of large air flow in metallurgy, machinery, chemical industry, building materials and other industries.

1、本除尘器采用离线清灰脉冲喷吹清灰技术，克服了常规脉冲除尘器和分室反吹除尘器的缺点，清灰能力强，除尘效率高，排放浓度低，漏风率小，能耗少，钢耗少，占地面积少，运行稳定可靠，经济效益好。适用于冶金、建材、水泥、机械、化工、电力、轻工行业的含尘气体的净化与物料的回收。

1. The dust collector adopts off-line ash cleaning pulse injection ash cleaning technology to overcome the shortcomings of conventional pulse dust collector and room based reverse flow bag dust collector with advantages of strong dust cleaning ability, high dust removal efficiency, low emission concentration, low air leakage rate, less energy consumption, less steel consumption, less occupation area, stable and reliable operation and good economic benefits. This dust collector is suitable for purification of dusty gas and material recovery in metallurgy, building materials, cement, machinery, chemical industry, electric power and light industry.
2、由于采用离线清灰脉冲喷吹清灰，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，压缩空气的气耗量可大为降低。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 off-line pulse injection ash cleaning, the purpose of ash cleaning can be achieved once, so the ash cleaning cycle is prolonged, the energy consumption of ash cleaning is reduced, and the gas consumption of compressed air is greatly reduced. At the same time, the fatigue degree of filter bag and pulse valve is also reduced accordingly, so as to double the life of filter bag and valve plate.
3、检修换袋可在不停系统风机，系统正常运行条件下分室进行。滤袋袋口采用弹性涨圈，密封性能好，牢固可靠。滤袋笼骨采用环形，减少了袋与笼骨的磨擦，延长了袋的寿命，又便于卸袋。

3. Maintenance and change-over of bags can be carried out in sperated houses without stopping the fan of the system and under the normal operating conditions of the system. The bag opening of the filter bag adopts an elastic packing ring with good sealing performance and is firm and reliable. The cage bone of the filter bag is circular, which reduces the friction between the bag and cage bone, prolongs the life of the bag and facilitates the unloading of the bag.
4、采用上部抽袋方式，换袋时抽出骨架后，脏袋投入箱体下部灰斗，由人孔处取出，改善了换袋操作条件。

4. The dust collector adopts the upper bag extraction method. After the skeleton is removed when changing the bag, the dirty bag is put into the lower ash bucket of the box and taken out from the manhole, which improves the operation conditions for changing the bag.
5、箱体采用气密性设计，密封性好，检查门用优良的密封材料，制作过程中以煤油检漏，漏风率很低。

5. The box body is designed with air tightness with good sealing property and excellent sealing material for inspection door. Kerosene is used to detect leakage in the manufacturing process, and the air leakage rate is very low.
6、进、出口风道布置紧凑，气流阻力小。

The inlet and outlet air ducts are compact and the air flow reesistance is samll.
