二、 LMC长袋脉冲袋式除尘器工作原理 

Second, the LMC long bag pulse bag filter working principle


  LMC长袋脉冲袋式除尘器主要由上箱体、中箱体、灰斗、卸灰系统、喷吹系统和控制系统等几部分组成,并采用下进气分室烟气净化结构。含尘烟气由进风口经中箱体下部进入灰斗;部分较大的尘粒由于惯性碰撞、自然沉降等作用直接落入布袋除尘器灰斗,其它尘粒随气流上升进入到袋式收尘器各个滤袋室。经除尘滤袋过滤后,尘粒被阻留在除尘布袋外侧,净化后的气体由滤袋内部进入脉冲除尘器上箱体,再通过提升阀、出风口、通过引风机达标排入大气。灰斗中的粉尘定时或连续由螺旋输送机及刚性叶轮卸料器卸出。随着过滤过程的不断进行,除尘器滤袋外侧所附积的粉尘不断增加,从而导致袋布袋除尘器本身的阻力也逐渐升高。当阻力达到预先设定值时,脉冲清灰控制器发出信号,首先令一个布袋除尘器袋室的提升阀关闭以切断该室的过滤气流,然后打开电磁脉冲阀,压缩空气由气源顺序经气包、脉冲阀、喷吹管上的喷嘴以极短的时间( 0.065~0.085秒)向除尘滤袋喷射。压缩空气在箱内高速膨胀,使滤袋产生高频振动变形,再加上逆气流的作用,使滤袋外侧所附尘饼变形脱落。在充分考虑了粉尘的沉降时间(保证所脱落的粉尘能够有效落入灰斗)后,提升阀打开,此布袋除尘器袋室滤袋恢复到过滤状态,而下一袋室则进入清灰状态,如此直到最后一袋室清灰完毕 为一个周期。 LMC长袋脉冲袋式除尘器是由多个独立的室组成的,清灰时各室按顺序分别进行,互不干扰,实现长期连续运行。上述清灰过程均由脉冲清灰控制器进行定时或定压自动控制。

LMC long bag pulse bag filter is mainly composed of enclosure, the enclosure, ash hopper, discharge system, injection system and the control system of several parts, such as flue gas purification and adopt the inlet chamber structure. Protecting gas inlet by the cabinet bottom into the hopper; Part of the larger dust particles such as inertia collision, natural sedimentation effect directly into the bag precipitator hopper, other dust particles with the air currents to rise into the bag type dust collector filter bag chamber. After dust filter bag filter, dust particles be trapped dust bag outside, after purification, the gas inside the filter bag from the case on pulse dust catcher, valves, outlet, through ascension by induced draft fan standard atmosphere. The dust ash hopper periodic or continuous rigid impeller by screw conveyor and discharger discharge. Along with the ongoing filtering process, filter the dust filter bag outside of the attached product continues to increase, leading to the bag bag precipitator itself resistance also gradually rise. When the resistance reaches the preset values, pulse dust controller signal, first make a cloth bag dust collector bag chamber of the filtered air lift valve closed to cut off the room, and then open the electromagnetic pulse valve, compressed air by air order bullishness of package, pulse valve, spray nozzle on the torch in a very short time (0.065 ~ 0.085 seconds) to the dust filter bag. Compressed air in the high-speed expansion in the cabinet, make the filter bag produces high frequency vibration deformation, plus the role of reverse airflow, the filter bag the lateral deformation of dust cake off. In full consideration of dust settling time (dust can effectively guarantee the loss into ash hopper), lift valve is opened, the bag bag filter chamber filter bag back to the filter state, while the next bag room into dust, so until completion of the last of the ash removal For a cycle. LMC long bag pulse bag filter is composed of multiple independent room, soot cleaning the room when the order separately, noninterference, achieve long-term continuous operation. The soot cleaning process are conducted by pulse wave sootblower controller timing or constant pressure automatic control.
