詳細描述

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，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的增加，當濾料兩側(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物料回收治理和凈化收集。

三、工作原理

當含塵氣體由進風口進入除塵器，首先碰到進出風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)。

One、 product overview

Bag type dust collector is a kind of dry dust filtering device. Filter used for a period of time, due to the sifting, collision, retention, diffusion, electrostatic and other effects, the bag surface of a layer of dust, this layer of dust known as the first layer, in which the future course of the movement, became the first layer mainly filter layer filter material, rely on the role of the early levels, larger mesh the filter can get a higher filtration efficiency. As the dust on the filter surface accumulation, efficiency and resistance of the dust collector are increased correspondingly, when the filter pressure difference on both sides is large, will put some has attached to small dust particles in the filter on the squeeze in the past, so that the precipitator efficiency decline. In addition, the resistance of the dust collector is too high will make the dust removal system of the wind dropped significantly.Therefore, the dust collector resistance reaches a certain value, to timely cleaning. Cleaning can not be destroyed when the first layer, to avoid reduced efficiency.

Two、 the scope of application

Solid separation we dye, pharmaceutical, plastic and printing factory, paint factory, food processing,flour, electronic industry, wood processing and other fields of liquid and fine material recoverytreatment and purification collection.

Three、the principle of work

When the dust contained gas from the inlet into the dust, met at the air inlet and outlet of theinclined plate and the middle baffle, flow turned into ash hopper, while the air flow speed slow down,under the inertia effect, gas dust settling into the hopper of coarse particles directly, since the role of airflow with dust in advance, after folding to filter bag dust through with internal metal skeletontrapped in the outer surface of the filter bag, purified gas into the filter bag chamber bottom clean room, pool to the discharge outlet. The process of dust containing gas through the filter bagcleaning, along with the increase of time more and more dust deposition in the filter bag, bagresistance increases, causing the air handling gradually reduced, must carry on the cleaning of the bag, so that the product of shedding in the filter bag dust filter bag surface, regeneration. Clear the dust falls into the bucket, the ash discharge system and discharged out of the machine body.Thereby the deposition in the filter bag dust cycle of the pulse jet cleaned, the purification of gaspassed normally, ensure the normal work of the dust removal system.

Four,、product structure

Body structure of bag type dust collector is mainly composed of an upper box body, a box body, the middle lower case (Hui Dou), the ash cleaning system and ash body parts. Device performance of bag type dust collector is good or bad, in addition to the correct choice of bag material, ash cleaning system plays a decisive role in the bag type dust remover. Therefore, the ash cleaningmethod is one of the characteristics that distinguish bag type dust collector, an important link in the operation is also a bag type dust collector.
