The working principle of bag dust removal equipment is to pass the dust and flue gas through a filter material (bag) to allow the dust particles to be filtered. Large and coarse particles of dust mainly rely on inertial collisions to allow large dust to settle. The small dust particles mainly rely on diffusion and sieving, so that the dust is isolated outside the surface layer of the bag, and finally the clean air is discharged.
处理风量决定着 布袋粉尘除尘设备 的规格大小，一般处理风量都用工况风量。 The air volume of the bag dust removal equipment determines the size of the bag dust removal equipment . Generally, the working air volume is used for the air volume. 布袋粉尘除尘设备 的烟气处理温度已经确定，而气体又采取稀释法冷却时，处理风量还要考虑增加稀释的空气量 When designing, you must pay attention to the place where the dust collector is used and the temperature of the flue gas. If the flue gas treatment temperature of the bag dust removal equipment has been determined, and the gas is cooled by the dilution method, the air volume to be treated must be increased to increase the amount of diluted air
考虑今后 的种种 变化，风量设计指值在正常风量基础上要增加 5% ～ 10% 的保险系数，否则今后一旦工艺调整增加风量， 布袋粉尘除尘设备 的过滤速度会提高，从而使设备阻力增大，甚至缩短滤袋使用寿命，也将成为其他故障频率急剧上升的原因，但若保险系数过大，将会增加 布袋粉尘除尘设备 的投资和运转费用 。 When choosing bag dust removal equipment, we must consider various changes in the future . The air volume design index should increase the insurance factor by 5% to 10% based on the normal air volume . Otherwise, once the process is adjusted to increase the air volume, the bag dust removal equipment 's The filtration speed will increase, which will increase the resistance of the equipment, and even shorten the service life of the filter bag. It will also cause other failure frequencies to rise sharply. However, if the insurance factor is too large, the investment and operating costs of bag dust removal equipment will increase .
布袋粉尘除尘设备 的 型号 、滤料的种类及特性的不同而有很大差异，处理风量一经确定，即可根据确定的过滤风速来决定所必须的过滤面积。 The filtering wind speed varies greatly depending on the type of bag dust removal equipment , the type and characteristics of the filter material. Once the processing air volume is determined, the necessary filtering area can be determined according to the determined filtering wind speed.
The working principle of bag dust removal equipment is generally divided into the following two types:
可采用在线清灰和离线清灰两种方法。 Bag dust removal equipment can adopt two methods: online cleaning and offline cleaning. 对带有粉 尘 的 气体过滤，在线清灰过滤及清灰时对系统波动影响小，但清灰不彻底，不能在线检修。 On-line ash cleaning refers to the fact that the filter bag still filters the gas with dust during pulse blowing. The on- line ash cleaning and filtering have little effect on the system fluctuation, but the cleaning is not complete and cannot be repaired online.
布袋粉尘除尘设备 内部分成若干个过滤室，每个袋室的净气室上独立安装离线阀、气缸和电磁脉冲阀等压缩气控制系统，在对每个过滤室进行脉冲清灰喷吹前，通过离线阀首先关闭这个袋室，使该滤室在没有烟气过滤情况下进行清灰，因此离线清灰效果更彻底，且能在线检修，缺点是增加离线机构、造价高、清灰时对系统烟气波动有影响等。 Offline ash cleaning refers to dividing the inside of the bag dust removal equipment into several filter chambers. The compressed air control systems such as offline valves, cylinders, and electromagnetic pulse valves are independently installed on the clean room of each bag chamber. Each filter chamber is pulsed. Before the ash cleaning and blowing, the bag chamber is closed first through the off-line valve, so that the filter chamber can be cleaned without smoke filtration. Therefore, the off-line ash cleaning effect is more thorough and can be repaired online. The disadvantage is that it increases the offline mechanism and cost High and dust removal will affect the flue gas fluctuation of the system.
The working principle of bag dust removal equipment in the design must not only design a reasonable filtering speed and guide the technology to make the airflow uniform, but also select a reasonable airflow rising speed according to the particle size, concentration, and working conditions to ensure the extension Filter bag life.
