HCDMC長袋低壓脈沖除塵器技術簡介
該產品綜合了分室反吹和脈沖清灰兩類收塵器的優點,克服了分室反吹清灰強度不足和一般脈沖清灰粉塵再附缺點,使清灰效率提高,噴吹頻率大為降低。HCDMC型收塵器還使用淹沒式脈沖閥,降低了噴吹氣源壓力。這樣,設備運行能耗降低,濾袋、脈沖閥的壽命延長,綜合技術性能大大提高。本系列收塵器設計新穎,與常規脈沖收塵器相比,有以下明顯特點。
1.分室離線清灰,效率高,粉塵不再附。
2.噴吹周期可比一般脈沖延長2倍以上。
3.氣源壓力由常規型的0.5~0.7Mpa降至0.4~0.6Mpa。
4.濾袋和脈沖閥壽命提高2倍以上。
5.處理高溫、高濃度含塵氣體過濾風速可達1.0m/min。
6.濾袋袋口采用彈簧漲緊結構,拆裝方便,密封性好。
7.PLC控制器能自動控制,清灰、卸灰、超溫報警。

HCDMC Series Long Bag Pulse Dust Collector
The technologies indroduction of HCDMC Series Long Bag Low Pressure Pulse Dust Collector
The product collects the advantages of two kinds of dust collectors like chambered reverse blow and pulse ash removal, overcoming the shortcomings like the weak intensity of ash removal of reverse blow and second attachment of common pulse ash removal dust, and makes the ash removal efficiency be improved and jetting frequency reduced greatly.
The flooded pulse valve has also been used in HCDMC Series Dust Collector and jetting gas supply pressure is reduced. Therefore, the energy consumption of equipment running is reduced; using life of filtering bag and pulse valve prolonged, and integrated technical performance improved greatly. Comparing with common pulse dust collectors, this dust collector has the clear following characteristics with unique design:
1.Chambered ash removal offline be adopted, high efficiency and no second attachment of dust.
2.Comparing with other pulse, jetting period can be prolonged more than double.
3.The gas supply pressure will reduced from the conventional type 0.5~0.7 Mpa to 0.4~0.6 Mpa.
4.The using life of filtering bag and pulse valve will be improved more than double.
5.The filtering wind velocity for handling high temperature and high concentration dust-contained air can reach 1.0 m/min. 
6.The tightened structure of spring is used in the bag mouth of filtering bag, convenient disassembling and assembling and fine leak tightness.
7.The PLC controller can control automatically, remove dust, dusting and give an over temperature warning.
 
HCDMC型長袋低壓脈沖袋收塵器工作原理
含塵煙氣由入口進入塵氣通道,然后折下進入灰斗。當氣流撞擊導流板,轉向塵氣袋室時,粗顆粒將靠慣性下落灰斗底部,細粉塵隨氣流上升,氣流穿過濾袋時,粉塵即被阻留在濾袋表面。凈氣通過各濾袋口匯集到凈氣箱內,再由各室出風蝶閥進入凈氣排風道排出。
HCDMC型袋收塵器為分室離線清灰,每室濾袋分成數組,每組數條。隨過濾過程的不斷進行,濾袋外表層積塵逐漸增多,從而使收塵器阻力升高,當阻力升至一定范圍時(1200~1500),清灰控制系統(PLC機)發出信號。首先關閉切換閥打開脈沖閥,壓縮空氣通過噴管向每條濾袋噴射氣流,使濾袋產生變形、震動,達到清灰的目的。清灰結束后,切換蝶閥再次打開,收塵器又進入過濾狀態,互不干擾,實現了長期連續作業,提高了清灰效果。
 
Working principles of HCDMC Series Long Bag Low Pressure Pulse Dust Collector
The dust-contained smoke enters into dust gas passage from the inlet and then into ash hopper by turning. When the air stream is striking stream guide plate and turning to dust-contained air bag chamber, the thick particles will fall into ash hopper by inertia and thin flour dust rise with air stream, and flour dust be stopped and kept on the surface of filtering bag immediately when air stream is passing through filtering bag. The cleaning gas will be collected to cleaning gas box through all bag mouths of filtering bags and discharged by the entering of air-out butterfly valve of all chambers into cleaning gas exhaust passage.
The HCDMC Series Bag Dust Collector is chambered ash offline, filtering bags of every chamber are divided into a couple of groups, and there are a couple of pieces in every group. With the constant running of filtering process, the dust attached and accumulated outside filtering bag is increasing and make the resistance of dust collector be rising. When the resistance reaches a certain range(1200~1500),the ash removal instruction will be sent out from ash removal control system(PLC).Make the switching valve be closed and open pulse valve firstly, and the compressed air will inject air stream to every piece of filtering bag through spray pipe and make the filtering bag produce deformation and vibration, thereby goal of ash removal is reached. After the ash removal, open the switching butterfly valve again and make dust collector be in the filtering state and no interfering, and realize the long constant operation and improve ash removal effect.
