生物质热风炉布袋除尘器性能特点

生物质热风炉的效率一般都在80%以上,热风炉型号大,燃烧的更充分,热风炉的效率也就更高。最高的达到了88.3%,比燃煤热风炉平均效率水平高15%。虽然生物质热风炉的效率很高,但是还是会产生对环境有污染的灰尘。所以需要有对应的除尘器来解决。生物质热风炉布袋除尘器就应运而生。生物质热风炉布袋除尘器其处理的工艺是,将每台热风炉生产过程中产生的烟气,分别进行处理。热风炉产生的烟气。粉尘由吸尘管道进入旋风除尘器,此时烟尘中的大颗粒在旋风除尘器的离心力的作用下进行分离,大颗粒粉尘由旋风除尘器排出,细小颗粒粉尘进入布袋除尘器。经过滤袋过滤,通过脉冲吹打将粘附在布袋表面的

The efficiency of biomass hot-blast stove is generally more than 80%. The type of hot-blast stove is large, the combustion is more full, and the efficiency of hot-blast stove is higher. The highest is 88.3%, which is 15% higher than the average efficiency of coal-fired hot blast stove. Although the efficiency of biomass hot blast stove is very high, it still produces dust which pollutes the environment. Therefore, the corresponding dust collector is needed to solve the problem. Bag dust collector of biomass hot blast stove came into being at the historic moment. The bag filter of biomass hot blast stove deals with the flue gas produced in the production process of each hot blast stove separately. Smoke from a hot blast stove. Dust enters the cyclone dust collector through the dust collecting pipe. At this time, the large particles in the dust are separated under the centrifugal force of the cyclone dust collector. The large particles are discharged by the cyclone dust collector, and the fine particles enter the bag dust collector. It is filtered by a filter bag and adhered to the surface of the cloth bag by pulse blowing.

粉尘先集中在除尘器的灰斗内,利用下料控制器进行回收或利用。经布袋除尘器处理过后的净气通过风机由烟囱排入大气。经过布袋除尘器对热风炉含尘烟气的处理,可减小烟尘对周边环境的污染,达到清洁的生产目的。

Dust first concentrates in the dust hopper of the dust collector, and is recycled or utilized by the feeding controller. The purified air after treatment by bag filter is discharged into the atmosphere through the fan from the chimney. The treatment of dust-containing fume from hot blast stove by bag filter can reduce the pollution of fume to the surrounding environment and achieve the purpose of clean production.

生物质热风炉布袋除尘器性能特点:

Performance characteristics of bag filter for biomass hot blast stove:

1、采用下进风,对含尘气体起到预收尘的作用,避免了含尘气体直接冲刷布袋,降低了含尘气体的粉尘浓度,延长了滤袋与脉冲电磁阀的寿命。

1. The use of downdraft can pre-collect the dust-containing gas, avoid the direct washing of the bag by the dust-containing gas, reduce the dust concentration of the dust-containing gas, and prolong the life of the filter bag and the pulse solenoid valve.

2、布袋除尘器密封材料均采用耐高温材料。

2. The sealing materials of bag filter are all made of high temperature resistant materials.

3、清灰喷吹管采用加长型,使脉冲电磁阀远离高温烟气,避免脉冲电磁阀阀片高温受损。

3. Dust cleaning nozzle is lengthened to keep the pulse solenoid valve away from high temperature flue gas and avoid high temperature damage of the valve sheet of the pulse solenoid valve.

4、滤袋采用耐高温滤袋,处理烟气温度<250℃。

4. High temperature resistant filter bag is used to treat flue gas temperature less than 250 C.

5、滤袋袋口采用弹性涨圈,密封性能好,牢固可靠。

5. The filter bag mouth adopts elastic ring, which has good sealing performance and is firm and reliable.

6、滤袋骨架采用圆形,减少了滤袋与骨架的磨擦,延长了滤袋的寿命,又便于卸袋。

6. The filter bag skeleton is circular, which reduces the friction between the filter bag and the skeleton, prolongs the service life of the filter bag and facilitates the unloading of the bag.

7、采用上部抽袋方式,换袋时打开顶盖门,抽出骨架后即可换袋,改善了换袋操作条件。

7. Upper bag-pulling mode is adopted. When changing bags, the top door is opened, and the bag can be changed after the skeleton is removed, which improves the operating conditions of bag-changing.

8、清灰控制采用定时控制,按设定时间,每隔一个清灰周期,各排滤袋依次清灰一遍。

8. Cleaning control adopts timing control. According to the set time, every other cleaning cycle, each filter bag cleans the ash one time in turn.
