低压长袋脉冲除尘器

详细描述

 

主要性能特点

低压长袋脉冲是在总结各种袋式除尘器的基础上发展起来的一种新型、高效袋式除尘器。它采用离线低压脉冲喷吹清灰技术,防止了粉尘再附与失控问题,增强了滤袋的清灰效果,提高了过滤速度,节省清灰能耗和延长滤袋的寿命。低压长袋脉冲袋式除尘器采用PLC可编程序控制器,自动控制清灰、输灰的全过程。因此,该除尘器是一种处理风量大、清灰效果好、除尘效率高、运行可靠、维护方便、占地面积小的大型除尘设备。

Brief introduction:

Low pressure and long bag impulse dust collector is a new type and high efficiency dust collector that developed from types of bag dust collector, it uses off-line low-pressure impulse blow ash removal technique, preventing the dust from adhering again and losing control that strengthens ash discharge effect, improves filter speed, saves ash discharge power and lengthens filtering bag using age. Low pressure and long bag impulse dust collector uses PLC programmable controller, controlling the whole process of ash discharge and ash transport. Thus, this dust collector has a large air blowing quantity, good ash discharge effect, high dedust efficiency, reliable operation, convenient maintenance, small floor area.


   低压长袋脉冲袋式除尘器工作原理:
  
本低压长袋脉冲袋式除尘器主要由灰斗、过滤室、净气室、支架、提升阀、喷吹清灰装置等部分组成。工作时,含尘气体由风道进入灰斗。大颗粒的粉尘直接落入灰斗底部,较小的粉尘随气流转折向上进入过滤室,并被阻留在滤袋外表面,净化了的烟气进入袋内,并经袋口和净气室进入出风倒,由排风口排出。
  
随着过滤的不断进行,滤袋外表面的粉尘不断增加,设备阻力随之上升。当设备阻力上升到一定值时,应进行清灰操作,清除滤袋表面的积灰。

Operational principle:

The major function part of low pressure and long bag impulse dust collector are ash bucket, filtering room, air purify room, supports, lift valve and blowing ash discharge devices。 When the collector is working, gas contained dust flows into ash bucket through air pipe。 The dust has larger size drops on the bottom of ash bucket directly; the dust has smaller size is brought up by updraft flowing into filtering room, screened on the surface of filter bag as well; purified gas flows into filter bag, then flows into purify room from filter bag mouth, finally the gas is discharged from outlet。


With continuously filtering, dust retained on filter bag surface increases, the machine resistance rises as well. When the resistance reaches a certain number, it should be cleaned the dust retained on filter bag surface.


   低压长袋脉冲袋式除尘器性能特点:
1.
低压长袋脉冲袋式除尘器采用低压脉冲喷吹技术,清灰效率高,能耗低。
低压长袋脉冲袋式除尘器使用直通式低压脉冲阀。喷吹压力只有0.20。4MPa,阻力低,启闭快,清灰能力强。由于清灰效果好,清灰周期长,降低了反吹气体的能耗。
2.
脉冲阀使用寿命长,可靠性好。
由于喷吹压力低(0。20.4MPa),脉冲阀膜片承受的压力和启闭时的冲击力较低。同时由于清灰周期较长,脉冲阀开启次数相应减少,从而延长了脉冲阀的使用寿命,提高了脉冲阀的使用可靠性。
3.
设备运行阻力小,喷吹效果好。
低压长袋脉冲袋式除尘器采用分室脉冲反吹离线清灰方式,避免了粉尘被反复吸附的现象,提高了脉冲喷吹清灰的效果,降低了布袋阻力。
4.
滤袋装拆方便,固定可靠
低压长袋脉冲袋式除尘器采用上部抽装方式,换袋时,从除尘器净气室抽出滤袋骨架,将脏袋投入灰斗,由灰斗入孔取出,改善了换袋环境。滤袋靠袋口的弹性涨圈固定在花板孔上,固定牢固,密封性好。
5.
风道采用集合管布置,结构紧凑。
6.
采用先进的PLC可编程序控制器除尘器的运行全过程。
使用压差或定时两种控制方式,可靠性高,使用寿命长,便于用户操作和使用。


performance characteristics:

1。 Low pressure and long bag impulse dust collector uses Low pressure impulse blowing technique, which has high ash discharge efficiency and low power consumption。

Low pressure and long bag impulse dust collector uses straightway low pressure impulse valve。 Blowing pressure is only 0。2~0。4MPa, the resistance is low, start and stop speed is fast and ash discharge ability is good。 Due to its strong ash discharge ability, the discharge cycle is long but the power consumption is reduced。

2.Long impulse valve using age, reliable performance。

Thanks to low blowing pressure(0.2~0.4MPa), impulse valve membrane bears lower pressure and lower impact force when machine starts and stops. Because of the long ash discharge cycle, impulse valve opening times is reduced and impulse valve using age is lengthened, which improve impulse valve practicability.

3.Small running resistance, good blowing efficiency。

Low pressure and long bag impulse dust collector uses locellus impulse back blowing ash removal technique, which avoids dust being absorbed again and again, improves impulse ash blowing removal efficiency and reduces running resistance as well。

4.More convenient for assembly and dis-assembly, stable installation.

Low pressure and long bag impulse dust collector uses headpiece take and install method, when changing new filtering bag, take out the old bag skeleton from purify room, put the old bag into dust bucket and get it out, this method improves bag changing environment a lot. Filtering bag is fasten on ceiling holes depending on its elasticity, which has firm installation and good hermetically.

5.Wind channel is arrayed with manifold pipes, the structure is well-knit.

6。The dust collector uses the advantaged PLC programmable controller to control whole running process.

The control ways can be classified as differential pressure control and timing control, both of them are credible, serviceable and convenient for operation.
