脈沖單(dan)機除塵(chen)(chen)器(qi)(qi)是我公司消化吸收國(guo)內(nei)外同類產品(pin)經改進后(hou)設計而成的小(xiao)型袋除塵(chen)(chen)器(qi)(qi),除塵(chen)(chen)器(qi)(qi)采(cai)用(yong)脈沖噴吹的清(qing)灰效果好,凈(jing)化效率高處理風(feng)量大濾帶壽(shou)命長維修工作量小(xiao),運行安全可(ke)靠的優點廣泛用(yong)于冶金(jin)、建材(cai)、機械、化工、礦(kuang)山等各(ge)種工礦(kuang)企業非纖維粉工業粉塵(chen)(chen)的除塵(chen)(chen)凈(jing)化。
本(ben)系列除塵器(qi)共有(you)六(liu)個規格(ge):每種(zhong)規格(ge)又可分(fen)為標準帶灰(hui)塵式(shi)A型(xing)和敞開法蘭式(shi)(無(wu)灰(hui)塵)B型(xing)二(er)種(zhong)。其結構主(zhu)要由過濾(lv)室(shi)、濾(lv)袋、凈(jing)氣室(shi)、灰(hui)斗、卸灰(hui)閥、脈沖(chong)噴吹裝置、電(dian)控箱(xiang)等組成。箱(xiang)體(ti)全部采(cai)用焊接結構,檢修門用泡沫橡膠條密封保(bao)證除塵器(qi)嚴密不漏風。
工作原理如下:含(han)塵(chen)(chen)氣(qi)體由灰(hui)斗(dou)(或(huo)下部(bu)敞(chang)開式法蘭)進入(ru)過(guo)濾(lv)(lv)室,較粗顆粒直接落入(ru)灰(hui)斗(dou)或(huo)灰(hui)倉,含(han)塵(chen)(chen)氣(qi)體經(jing)濾(lv)(lv)袋(dai)過(guo)濾(lv)(lv)粉塵(chen)(chen)阻留于(yu)袋(dai)表,凈氣(qi)經(jing)袋(dai)口(kou)到(dao)凈氣(qi)室由風機排入(ru)大氣(qi)。當濾(lv)(lv)袋(dai)表面的(de)粉塵(chen)(chen)不斷增加導致(zhi)設備阻力(li)上(shang)升到(dao)設定(ding)值時,時間(jian)繼電器(qi)(或(huo)微差壓(ya)控制器(qi))輸出信號,程控儀(yi)開始工作。逐個開啟脈沖閥,使壓(ya)縮空氣(qi)通過(guo)噴口(kou)對濾(lv)(lv)袋(dai)進行吹(chui)清灰(hui)使濾(lv)(lv)袋(dai)突然膨脹在反向氣(qi)流的(de)作用下,附于(yu)袋(dai)表的(de)粉塵(chen)(chen)迅速(su)脫離濾(lv)(lv)袋(dai)落入(ru)灰(hui)斗(dou)(或(huo)灰(hui)倉),粉塵(chen)(chen)由卸灰(hui)閥排出,全部(bu)濾(lv)(lv)袋(dai)噴吹(chui)清灰(hui)結(jie)束后除塵(chen)(chen)器(qi)恢復正常(chang)工作。
