天宏脉冲布袋除尘器是怎么来收集灰尘的

现在越来越多的厂家为了****环境的污染,上了治理灰尘的除尘设备,那么大家知道布袋除尘器是怎么来处理粉尘的吗?布袋除尘器是如何收集粉尘的,天宏环保就以本公司生产的DMC脉冲布袋除尘器为例向大家做一简单介绍。

布袋除尘器以除尘*,结构比较简单,运行比较稳定,初始较少,维护方便等诸多优点正被用于各种除尘系统中。The bag dust collector ha*any advantages such as high dust removal efficiency, simple structure, stable operation, less initial investment, convenient maintenance and so on. How to collect dust in cloth bag dust remover, Tianhong environmental protection take the DMC pulse bag filter produced by our company as an example to make a brief i*oductio*everyone.

含尘气体在引风机吸引力的作用下进入灰斗,经导流板后被均匀分配到各条滤袋上。粉尘被拦截在滤袋外表面,气体则穿过滤袋,经过净气室后排出。The dust-containin*as enters the ash hopper under the force of the induced fan and is evenly distributed to each filter bag after passing through the guide plate. The dust is intercepted on the outer surface of the filter bag, and the gas passes through the filter bag.

在滤袋外表面上的粉尘会导致滤袋透气性的减少,使除尘器的阻力不断增加,等到阻力达到设定植(差压控制)或是过滤的时间达到设定值(时间控制),通常处于关闭状态的脉冲阀在脉冲喷吹控制仪PLC脉冲喷吹控制下打开****短暂的一段时间(0.1s左右),高压气体瞬间从气包进入喷吹管,并高速从喷吹孔喷出。高速气流喷入滤袋是还会产生数倍于喷射气体的二次引流。喷射气流与二次引流的共同作用使滤袋内侧的压力迅速升高,滤袋由原先内凹的形状变成外凸的形状,并在变形量达到较大值时产生一个很大的反向加速度,吸附在滤袋上的粉尘主要在这反向加速度作用下,脱离滤袋表面,落入灰斗,除尘器的阻力随之下降。Dust falling on the outer surface of the filter bag will reduce the permeability of the filter bag and increase the resistance of the dust collector until the resistance reaches the set plan*fferential pressure co*ol) or the filter time reaches the set value (time co*ol). The normally closed pulse valve opens for*ery short period of time (about 0.1 s) under the pulse injection co*ol of the pulse injection co*oller (PLC). High-speed airflow i* the filter bag will also produce several times a*uch gas as the secondary drainage. The combined action of jet flow and secondary drainage caused the pressure on the inside of the filter bag to rise rapidly, and the filter bag wa*ade from the original.

过滤状态  将粉尘从滤袋表面清除的过程称为清灰。清灰工作是一排一排进行的。脉冲阀每动作一次,一排滤袋就得到清灰。脉冲阀按照设定的时间间隔与顺序依次动作,直到完成一个循环。整台除尘器就完成了一个清灰周期。在差压控制方式时,下一个清灰周期的开始与否取决于除尘器的阻力。在时间控制方式时,下一个清灰周期的开始与否取决于过滤时间。差压控制方式可以使除尘器的阻力保持在一个动态稳定状态,还可以减少压缩空气的喷吹次数,减少压缩空气的消耗与滤袋的磨损,一般宜采用差压控制方式。The process of removing dust from the surface of the filter bag in the filter state is called ash removal. Ash cleaning is carried out in a row. Pulse valve each action, a row of filter bags to get ash removal. The pulse valve operates at set intervals and in sequence until a cycle is completed. The whole dust collector completes a ash removal cycle. In the differential pressure co*ol mode, the beginning of the next ash removal cycle depends on the resistance of the dust collector. In time co*ol, the start of the next ash removal cycle depends on the filter time. The differential pressure co*ol method can keep the resistance of the dust collector in a dynamic and stable state, and can also reduce the injection of compressed air. Frequency, reduce the c*umption of compressed air and filter bag wear, the general use of differential pressure co*ol.

清灰时,如提升阀为开启状态,清灰的滤袋仍在过滤烟气,则称之为在线清灰。反之,如清灰时,提升阀为关闭状态,清灰的滤室不过滤,则称之为离线清灰。清灰时,从滤袋表面脱落的粉尘入灰斗需要一定的时间。在线清灰状态下,一部分微小粉尘在未落入灰斗前,就有可能又被吸附现象叫做粉尘的“二次吸附”。离线清灰可以有效地消除这种二次吸附现象,因此清灰效果更好。When cleaning, if the lifting valve is open, the filter bag is still filtering *oke, it is called online ash cleaning. On the co*ary, the lifting valve is closed and the filter chamber is not filtered, so it is called off-line ash cleaning. It takes a certain amou*f time to enter the ash hopper from the dust falling off the surface of the filter bag. Under the condition of on-line ash cleaning, some micro-dust may be called "secondary adsorption" of dust before falling i* the ash hopper. Off-line ash removal can effectively eliminate this secondary adsorption phenomen*o the effect of ash removal is better.
