生物質熱風爐的效率一般都在80%以上,熱風爐型號大,燃燒的更充分,熱風爐的效率也就更高。最高的達到了88.3%,比燃煤熱風爐平均效率水平高15%。雖然生物質熱風爐的效率很高,但是還是會產生對環境有污染的灰塵。所以需要有對應的除塵器來解決。生物質熱風爐布袋除塵器就應運而生。生物質熱風爐布袋除塵器其處理的工藝是,將每臺熱風爐生產過程中產生的煙氣,分別進行處理。熱風爐產生的煙氣。粉塵由吸塵管道進入旋風除塵器,此時煙塵中的大顆粒在旋風除塵器的離心力的作用下進行分離,大顆粒粉塵由旋風除塵器排出,細小顆粒粉塵進入布袋除塵器。經過濾袋過濾,通過脈沖吹打將粘附在布袋表面的
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.
粉塵先集中在除塵器的灰斗內,利用下料控制器進行回收或利用。經布袋除塵器處理過后的凈氣通過風機由煙囪排入大氣。經過布袋除塵器對熱風爐含塵煙氣的處理,可減小煙塵對周邊環境的污染,達到清潔的生產目的。
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.
生物質熱風爐布袋除塵器性能特點:
Performance characteristics of bag filter for biomass hot blast stove:
1、采用下進風,對含塵氣體起到預收塵的作用,避免了含塵氣體直接沖刷布袋,降低了含塵氣體的粉塵濃度,延長了濾袋與脈沖電磁閥的壽命。
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、布袋除塵器密封材料均采用耐高溫材料。
2. The sealing materials of bag filter are all made of high temperature resistant materials.
3、清灰噴吹管采用加長型,使脈沖電磁閥遠離高溫煙氣,避免脈沖電磁閥閥片高溫受損。
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、濾袋采用耐高溫濾袋,處理煙氣溫度<250℃。
4. High temperature resistant filter bag is used to treat flue gas temperature less than 250 C.
5、濾袋袋口采用彈性漲圈,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、濾袋骨架采用圓形,減少了濾袋與骨架的磨擦,延長了濾袋的壽命,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,換袋時打開頂蓋門,抽出骨架后即可換袋,改善了換袋操作條件。
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、清灰控制采用定時控制,按設定時間,每隔一個清灰周期,各排濾袋依次清灰一遍。
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.
