袋式除尘器除尘效率怎么样

作者: admin 时间:2017-12-21 来源:未知

袋式除尘器除尘效率在这几年的案例中也证实了其高效的收尘率,而影响其除尘效率的有变化的烟气量,颗粒浓度,粉尘比电阻等等。
 
In recent years, the dust removal efficiency of bag filter has also been proved to be efficient in dust collection, and there are varying smoke volume, particle concentration, dust resistance and so on.
 
就说这烟气量,一般情况下,烟气量增加,除尘的效率下降。主要是因为烟气量增加后,含尘废气也逐渐增加,也减少了粉尘与带负电的气体离子结合机会,而且在电场区域的粉尘颗粒所受的电场力会对惯性力的束缚减弱。
 
In general, the amount of flue gas increases and the efficiency of dust removal decreases. It is mainly due to the gradual increase of dust and exhaust gas after the increase of flue gas volume, and the chance to combine dust with negatively charged gas ions. Moreover, the electric field force of dust particles in electric field will weaken the restraint of inertial force.

那么在布袋过滤含尘废气这一块,废气流速较快会影响到除尘的效率,更会增加除尘布袋的磨损。因此袋式除尘器要保持较高的除尘效率,是需要把控好运行的条件。那么袋式除尘器运行主要看哪些条件?
 
Then filter the dust in the bag, the fast velocity of the exhaust gas will affect the efficiency of the dust removal, and will increase the wear of the dust bag. Therefore, the bag type dust collector should maintain the high efficiency of dust removal, and it is necessary to control the operating conditions. So what are the main conditions for the bag filter to run?
 
袋式除尘器运行时候是需要关注下烟气的温度、出口压力以及废气的流速。这三点也会多多少少影响了除尘的效果。
 
It is necessary to pay attention to the temperature of the flue gas, the pressure of the outlet and the flow rate of the exhaust gas in the operation of the electric bag compound bag type dust collector. These three points will also affect the effect of dust removal.
