脈沖單機除塵器
脈沖(chong)單機除塵器(qi)是我公(gong)司消化吸(xi)收國內(nei)外(wai)同類(lei)產品(pin)經改進后設計而成的小型袋除塵器(qi)，除塵器(qi)采用(yong)脈沖(chong)噴(pen)吹的清(qing)灰效果好，凈化效率高(gao)處理風量大濾帶壽(shou)命長維(wei)修(xiu)工(gong)作量小，運行優點廣(guang)泛(fan)用(yong)于冶(ye)金、建材、機械、化工(gong)、礦山等各種工(gong)礦企業非纖維(wei)粉(fen)(fen)工(gong)業粉(fen)(fen)塵的除塵凈化。
本系列除塵器(qi)共(gong)有六個規(gui)格：每種(zhong)規(gui)格又可(ke)分為標準帶灰塵式A型和敞開法(fa)蘭式(無灰塵)B型二種(zhong)。其結(jie)構主要由過濾室、濾袋、凈(jing)氣(qi)室、灰斗(dou)、卸灰閥(fa)、脈沖噴吹(chui)裝置、電控箱等組成。箱體(ti)全部采用焊接(jie)結(jie)構，檢修門用泡沫橡膠(jiao)條密(mi)封保證除塵器(qi)嚴密(mi)不漏風。
工作原理如下：含塵(chen)氣(qi)(qi)(qi)體(ti)由灰斗(或下部敞開(kai)式法蘭)進入(ru)(ru)過(guo)(guo)濾(lv)(lv)室,較粗(cu)顆粒直接落(luo)入(ru)(ru)灰斗或灰倉,含塵(chen)氣(qi)(qi)(qi)體(ti)經濾(lv)(lv)袋(dai)(dai)過(guo)(guo)濾(lv)(lv)粉(fen)塵(chen)阻(zu)留(liu)于袋(dai)(dai)表，凈氣(qi)(qi)(qi)經袋(dai)(dai)口(kou)到凈氣(qi)(qi)(qi)室由風機排入(ru)(ru)大氣(qi)(qi)(qi)。當濾(lv)(lv)袋(dai)(dai)表面的(de)粉(fen)塵(chen)不斷增加導致設備阻(zu)力上升(sheng)到設定(ding)值時，時間繼電器(qi)(或微(wei)差壓控(kong)制器(qi))輸出(chu)(chu)信(xin)號，程控(kong)儀開(kai)始(shi)工作(zuo)。逐個開(kai)啟脈沖閥，使壓縮空(kong)氣(qi)(qi)(qi)通過(guo)(guo)噴口(kou)對(dui)濾(lv)(lv)袋(dai)(dai)進行吹清灰使濾(lv)(lv)袋(dai)(dai)突(tu)然膨脹在(zai)反向氣(qi)(qi)(qi)流的(de)作(zuo)用(yong)下，附于袋(dai)(dai)表的(de)粉(fen)塵(chen)迅速(su)脫離濾(lv)(lv)袋(dai)(dai)落(luo)入(ru)(ru)灰斗(或灰倉)，粉(fen)塵(chen)由卸(xie)灰閥排出(chu)(chu)，全部濾(lv)(lv)袋(dai)(dai)噴吹清灰結束后除塵(chen)器(qi)恢(hui)復正(zheng)常(chang)工作(zuo)。
