藍謙牌”布袋式除塵凈化器采用無紡布材質(zhì),達到不宜損壞和破損等情況。
一、產(chǎn)品概述
??袋式除塵器是一種干式濾塵裝置。濾料使用一段時間后,由于篩濾、碰撞、滯留、擴散、靜電等效應(yīng),濾袋表面積聚了一層粉塵,這層粉塵稱為初層,在此以后的運動過程中,初層成了濾料的主要過濾層,依靠初層的作用,網(wǎng)孔較大的濾料也能獲得較高的過濾效率。隨著粉塵在濾料表面的積聚,除塵器的效率和阻力都相應(yīng)的增加,當(dāng)濾料兩側(cè)的壓力差很大時,會把有些已附著在濾料上的細(xì)小塵粒擠壓過去,使除塵器效率下降。另外,除塵器的阻力過高會使除塵系統(tǒng)的風(fēng)量顯著下降。因此,除塵器的阻力達到一定數(shù)值后,要及時清灰。清灰時不能破壞初層,以免效率下降。
二、應(yīng)用范圍
? 染料、制藥、塑膠和印刷廠、涂料廠、食品加工、面粉、電子行業(yè)、木材加工等領(lǐng)域的液固分離及微細(xì)物料回收治理和凈化收集。
三、工作原理?
??當(dāng)含塵氣體由進風(fēng)口進入除塵器,首先碰到進出風(fēng)口中間的斜板及擋板,氣流便轉(zhuǎn)向進入灰斗,同時氣流速度放慢,在慣性作用下,氣體中粗顆粒粉塵直接沉降到灰斗,起預(yù)收塵的作用,氣流隨后折而向上通過內(nèi)部裝有金屬骨架的濾袋粉塵被捕集在濾袋的外表面,凈化后的氣體進入濾袋室下部清潔室,匯集到出風(fēng)口排出。含塵氣體通過濾袋凈化的過程中,隨著時間的增加而積附在濾袋上的粉塵越來越多,濾袋阻力增加,致使處理風(fēng)量逐漸減少,必須對濾袋進行清灰,使積附在濾袋表面的粉塵脫落,濾袋得到再生。清下粉塵落入灰斗,經(jīng)排灰系統(tǒng)排出機體。由此使積附在濾袋上的粉塵周期地脈沖噴吹清除,使凈化氣體正常通過,保證除塵系統(tǒng)正常工作。
四、產(chǎn)品構(gòu)造
??袋式除塵器本體結(jié)構(gòu)主要由上部箱體、中部箱體、下部箱體(灰斗)、清灰系統(tǒng)和排灰機構(gòu)等部分組成。袋式除塵器性能的好壞,除了正確選擇濾袋材料外,清灰系統(tǒng)對袋式除塵器起著決定性的作用。為此,清灰方法是區(qū)分袋式除塵器的特性之一,也是袋式除塵器運行中重要的一環(huán)。
