詳情介紹

HFGM系列高效除塵器由氣箱脈沖(Pulse-Plenum)除塵技術發展而來,這種除塵器集分室反吹和脈沖噴吹等諸類除塵器的優點,具有清灰能力強、除塵效率高、排放濃度低等特點,特別適合處理粉塵濃度高(高達1000 g/m3)的廢氣。
HFGM Series Gas Box Pulse Bag Dust Collector
The technologies introduction of HFGM Series Gas Box Pulse Bag Dust Collector
The high-efficiency dust collector of HFGM series is developed from the dust collection technology of pulse plenum, This kind of dust collector collects the advantages of some bag hose dust collectors like chambered reverse blow bag hose dust collectors and Jetting pulse bag hose dust collectors, with the characteristics of strong ash removal, high-efficiency dust collection, low discharging concentration and so on, which is specially fit for dealing with the waste gas of high concentration of flour dust ( high as 1000 g/m3).
HFGM氣箱脈沖袋除塵器的工作原理
HFGM氣箱脈沖袋除塵器采用下進氣分室結構。含塵煙氣由進風口進入灰斗;部分較大的塵粒由于慣性碰撞、自然沉降等作用直接落入灰斗,其它塵粒隨氣流上升進入各個袋室。經濾袋過濾后,塵粒被阻留在濾袋外側,凈化后的氣體由濾袋內部進入箱體,再通過提升閥、出風口排入大氣?;叶分械姆蹓m定時或連續由螺旋輸送機及分隔輪卸灰閥卸出。
    隨著過濾過程的不斷進行,濾袋外側所附積的粉塵不斷增加,從而導致袋除塵器本身的阻力也逐漸升高。當阻力達到預先設定值時,清灰控制器發出信號,首先令一個袋室的提升閥關閉以切斷該室的過濾氣流,然后打開電磁脈沖閥,以極短的時間(0.1~0.2秒)向箱內噴入0.5~0.7Pa的壓縮空氣。壓縮空氣在箱內高速膨脹,使濾袋產生高頻振動變形,再加上逆氣流的作用,使濾袋外側所附塵餅變形脫落。在充分考慮了粉塵的沉降時間(保證所脫落的粉塵能夠有效落入灰斗)后,提升閥打開,此袋室再次進入過濾狀態,而下一袋室則進入清灰狀態,如此一個周期。HFGM氣箱脈沖袋除塵器是由多個獨立的室組成的,清灰時各室按順序分別進行,互不干擾,實現長期連續運行。
上述清灰過程均由清灰控制器進行自動控制,分為定時式和定阻式兩種,可根據用戶的要求決定采用哪一種。
 
Working principles of HFGM Series Gas Box Pulse Bag Dust Collector
The gas box pulse bag dust collector of HFGM series has taken the chambered structure of lower air-in. The dust-contained flue gas enters into the dust hopper by air inlet, in which some of bigger dust particles fall into the dust hopper directly with the functions of inertial collision, natural settlement and so on, while the other dust particles enter into every bag chamber with the rising of air stream. After the filtering of filtering bag, the dust particles are stopped and kept outside filtering bag, and gas purified enters into box body from the inside filtering bag and be discharged into the air by poppet valve and air outlet. The flour dust in ash hopper is unloaded by screw conveyer and ducting valve of mesh division wheel in fixed time or constantly.
With the constant running of filtering process, the dust attached and accumulated outside filtering bag is increasing and make the resistance of dust collector itself be rising gradually. When the resistance reaches the preset value, the ash removal instruction will be sent out from ash removal controller. Make the poppet valve of one bag chamber be closed firstly to cut off the air stream of filtering in this chamber. Then open the electromagnetic pulse valve and inject the compressed air of 0.5~0.7 Pa to the inside box body with the very short time (0.1-0.2 second). The compressed air swells in the box body at high speed and makes the filtering bag produce high-frequency vibration and deformation and makes the dust cake attached outside filtering bag be deformed and fall off with the function of reverse air stream. After the full consideration of settlement time of flour dust ( make sure that the flour dust shed can fall into the ash hopper effectively), open the poppet valve and this bag chamber will be in the filtering state again and next bag chamber be in ash removal state, which is a period. The gas box pulse bag dust collector of HFGM series consists of lots of independent chambers. The ash removal will be taken separately from chamber to chamber in order and no interfering, and long constant running be realized.
All of the above ash removal processes are controlled by the ash removal controller automatically, divided into fixed time type and fixed resistance type, and we will decide to take which type according to the requirements of users.
