4 types of bag filter


4 types of bag filter:


(1) Upper air inlet and lower air inlet The upper air inlet means that the dust-containing airflow inlet is located in the upper part of the baghouse of the baghouse dust collector, and the airflow is consistent with the settling direction of the particulate dust. The down-entry wind type is that the dust-containing airflow inlet is located in the lower part of the bag chamber, and the airflow is opposite to the settling direction of the particulate dust. If it is viewed from the outside, but the bag room is provided with a deflector to diffuse the dust-containing airflow into the upper part of the bag room, it should be an up-wind type.


(2) Round filter type and flat filter type The round filter type refers to the cylindrical shape of the dust bag. Flat filter type refers to the filter bag is flat (envelope) trapezoidal, wedge-shaped and other non-cylindrical shapes.

4 types of bag filter (3) Suction and press-in suction means that the fan is located behind the bag filter and the bag filter works under negative pressure. Press-in means that the fan is located in front of the bag filter, and the bag filter works under positive pressure.


(4) Internal filter type and external filter type The internal filter type refers to the flow of dust-containing air flowing from the inside of the bag to the outside of the bag, and the dust is collected on the inside of the dust-removing cloth bag. External filtering means that the air flow containing dust flows from the outside of the bag to the inside of the bag, and the dust is collected on the outside of the bag. The outer filter round dust-removing cloth bag is usually sewn with flat filter material or hot-melt bonded. The diameter of the round bag can be Φ80 ~ Φ200mm, the most commonly used is Φ115 ~ Φ160mm, the bag length is generally 2 ~ 6m, and the longest is 8m. The outer filter round bag should be equipped with a frame to support the filter bag when in use, so that the round bag can maintain normal working condition under pressure. The size of the outer filter round bag and the frame are related to the dust removal effect and service life of the filter bag. The size of the synthetic fiber outer filter round bag and the frame should be loose, that is, the diameter and length of the outer filter round bag should be slightly larger than the size of the frame. For example, the outer filter round bag of Φ120mm should be equipped with a frame of Φ115mm, and the length should be 15 ~ 30mm longer than the frame, so that the filter bag has a certain amplitude when it is sprayed with dust. The size of the glass fiber outer filter round bag and the frame should be closely matched. For example, the outer filter round bag of Φ120mm should be equipped with a frame of Φ120mm, and the length is also consistent, so that the amplitude of the filter bag is small when the dust is sprayed, and the dust bag is prevented from being twisted and bent frequently.


Four types of bag dust collectors and their working principles:


气体 风机的负压通过管道吸入布袋除尘器的箱体内, 采用 布袋 除尘式 进行过滤,粉尘被 隔离在 布袋的表面 外层 ,净化后的 洁净 气体通过布袋 中心 进入风机, 风机吸入直接 从消声器上南 排出。 The dust-laden gas is sucked into the box of the bag filter by the negative pressure of the fan through the pipe, and the bag filter is used to filter the dust. The dust is isolated on the outer surface of the bag . The purified clean gas enters the fan through the center of the bag and is The fan suction is directly discharged from the upper side of the muffler .

 

布袋除尘器运行 时间的 增加 ,布袋的表面 外层 粉尘不断地增加,滤袋阻力随之上升,从而影响除尘器的除尘效果, 一般 采用了自 清灰机构进行 定时对滤袋进行喷吹 粘在布袋 外层 的粉尘抖落下来,落入灰斗抽屉中。 With the increase of the running time of the bag filter , the dust on the outer surface of the bag continuously increases, and the resistance of the filter bag increases accordingly, which affects the dust removal effect of the filter. Generally, a self- cleaning mechanism is used to spray the filter bag at regular intervals Blow , let the dust sticking to the outer layer of the cloth bag shake down and fall into the ash bucket drawer.
