除塵器冒煙和冒灰現(xiàn)像屬于嚴重損壞現(xiàn)象，應(yīng)立即停機檢修，下面凈化鋁材配件 http://www.jnjkjh.com/ 小編介紹一下冒灰和冒煙原因和處理辦法
Dust collector smoke and ash is now a serious phenomenon, should be immediately shut down for maintenance, cleaning aluminum parts below the small series to introduce the cause and process of smoke and ash
原因：布袋除塵器出風口的冒煙塵情況有兩種，一種是連續(xù)冒煙塵，即由于除塵濾袋破損嚴重，濾袋綁扎不牢脫落，或者布袋除塵器上下吊口不嚴密，上吊口與花板、花板與花板之間的連接不嚴密而造成的漏塵。另一種是瞬間冒煙塵，此種情況是除塵濾袋雖破損，但不甚嚴重，在布袋除塵器噴吹時出現(xiàn)瞬間冒煙塵。
Reasons: bag precipitator outlet of smoke dust condition has two, a is continuous take smoke, is due to severe damage to the dust filter bag, bag, lashing unstable off, or the cloth sack dust remover hanging mouth is not tight, hanging mouth and flower plate, flowers between the board and the board is not connected to the strict density caused by the leakage of dust. Another a kind of is instantly take smoke, this is dust filter bag, though damaged, but not very serious, when blowing bag type dust remover spray appear instantly take smoke.
因為當大部分除塵濾袋損壞時，應(yīng)進行全部更換，更換除塵布袋最好在除塵器停止工作時進行，此時應(yīng)將清灰控制器關(guān)閉，打開頂部的人孔門，便可拆卸布袋，拆卸時，先將袋籠取出，然后將布袋上口的彈簧圈捏成凹形，向上拉出除塵布袋，安裝新布袋前，應(yīng)將花板孔上的粉塵清理干凈。
Because when most of the dust filter bag damage should replace all, replaced with dust bag deduster stops working. At that time, will be cleared off the grey controller, open the top of manhole door, can remove the bag, demolition, the first bag cage out. Then the cloth bag upper coil molded into the concave, up out of the bag type dust collector installed new bag before, will take on a plate hole of a dust clean.
查找布袋除塵器冒煙塵的原因時，可根據(jù)出風口冒煙塵時與電磁脈沖閥，脈沖控制儀動作時所對應(yīng)的位數(shù)來判斷是哪排除塵濾袋漏塵。上揭蓋布袋除塵器亦可用手電筒從上箱體觀察孔查出漏塵的濾袋；或打開上揭蓋后再開脈沖控制儀，在噴吹過程中發(fā)現(xiàn)從哪個文氏管冒煙塵，就是那個除塵濾袋漏塵。然后，根據(jù)出現(xiàn)的問題進行處理。因為當大部分除塵濾袋損壞時，應(yīng)進行全部更換，更換除塵布袋最好在除塵器停止工作時進行，此時應(yīng)將清灰控制器關(guān)閉，打開頂部的人孔門，便可拆卸布袋，拆卸時，先將袋籠取出，然后將布袋上口的彈簧圈捏成凹形，向上拉出除塵布袋，安裝新布袋前，應(yīng)將花板孔上的粉塵清理干凈。
Find the cloth bag dust remover to run a smoke, according to a tuyere soot and electromagnetic pulse valve, pulse control instrument action corresponding to the digits to determine which row dust filter bag dust leakage. To uncover the cover cloth bag dust remover also flashlight can be used from the box on the observation hole check out the leakage of dust filter bag; or open exposing cover the reopen after the pulse control instrument, in the blowing process found from which the venturi tube take smoke is the dust filter bag dust leakage. Then, according to the problem of emergence. Because when most of the dust filter bag damage should replace all, replaced with dust bag deduster stops working. At that time, will be cleared off the grey controller, open the top of manhole door, can remove the bag, demolition, the first bag cage out. Then the cloth bag upper coil molded into the concave, up out of the bag type dust collector installed new bag before, will take on a plate hole of a dust clean.
布袋除塵器更換除塵濾袋時，要檢查分析其破損原因。影響除塵濾袋壽命的因素有粉塵的性質(zhì)，氣流的分布，除塵骨架的加工質(zhì)量等。如因濾袋框架焊接不牢，在程使用過程中開焊，將除塵濾袋剌破，應(yīng)及時焊好，并將除塵骨架毛刺焊渣磨平打光，或換新的除塵骨架。濾袋骨架通常是用直徑4毫米的鋼絲焊接而成的。常用的焊接方法有兩種，一種是用點焊機點焊，另一種是用氧-乙炔焊接。采用前一種方法，生產(chǎn)效率高，表面光滑，不易產(chǎn)生毛刺，變形小。除塵器不能使用破損的除塵布袋進行工作，否則會加速除塵器的報廢。當個別除塵布袋發(fā)生小面積破損時，為了節(jié)省開支，建議可以用舊的布袋或同樣材料新濾布將破洞補上使用，補洞方法是使用有機硅橡膠混合料進行粘接，只要粘接劑的使用溫度、化學(xué)性能與工藝狀況相適應(yīng)便可。采用后一種方法，生產(chǎn)效率低，表面粗糙，易變形。此外，還有的采用塑料框架，但這種框架不適于高溫下使用。在噴吹過程中，由于濾袋每清掃一次，將與除塵框架外表面摩擦一次，因此除塵濾袋使用到一定時間后，雖未損壞，但其內(nèi)表面與除塵框架接觸部位已有磨損，再裝時可根據(jù)磨損痕跡將原來的部位錯開，以避免在原繼續(xù)磨損，這樣可延長除塵濾袋的使用壽命。
Bag filter dust bag replacement, to check the damage reason analysis. The nature of factors affecting the life of the dust bag dust, air distribution, dust skeleton processing quality. Such as due to the filter bag frame welding rickety, in process used in the process of welding, dust filter bag to cut, should be timely welding, and the dust skeleton burr welding slag grinding polishing, or change a new dust collection skeleton. The filter bag frame is usually with a diameter of 4 mm steel wire and welded. There are two kinds of welding methods, one is the use of spot welding spot welding, the other is the use of oxygen - acetylene welding. Using the former method, the production efficiency is high, the surface is smooth, not easy to produce burr, deformation is small. Dust remover can not use the damaged dust bag to work, otherwise it will accelerate the removal of dust collector. When the individual dust bag damaged area is small, in order to save money, it is recommended can be worn bag or the same material new cloth will break the filled in the hole using, fill hole method is the use of silicone rubber blend materials bonding, as long as the adhesive temperature and chemical properties and technological conditions adapt to. After the use of a method, the production efficiency is low, the surface roughness, easy deformation. In addition, there is the use of plastic frame, but this framework is not suitable for high temperature use. In blowing process, the filter every cleaning time, and the outer surface of the dust removal frame friction time, so dust filter bag used to a certain time, although not damaged, but the inner surface and the dust removal frame contact parts of the existing wear, can re installed according to the wear traces will open the original Ministry of dislocation, in order to avoid in the original to wear, which can prolong the service life of the filter bag dust.
安裝布袋除塵器濾袋骨架時，對上揭蓋脈沖除塵器要注意把多孔板上的積灰清除干凈，以防接口與多孔板間不嚴密造成漏氣，影響凈化效率；噴吹管孔要對準文氏管中心，以保證噴吹效果。對側(cè)開門除塵器要注意上下吊口松緊得當，以防下吊口脫落和擰壞螺紋。
Installation of bag deduster filter bag skeleton of on uncovering pulse dust catcher should pay attention to the porous plate on the ash cleaning clean to anti interface and the porous plate between the imprecision caused by leakage on the purification efficiency; blowing hole to align the venturi tube center, in order to guarantee the blowing effect. On the side door dust collector should pay attention to the upper and lower hanging mouth elastic properly, in case of hanging mouth off and screw bad thread.
除塵布袋拆卸安裝時要注意不要與布袋除塵器金屬棱角碰撞，以防暗傷。
Dust bag removing installation should pay attention not to bag type dust collector and metal edges to prevent collision, injury.
布袋除塵器冒煙塵的原因重點所在：
Reasons for the dust removal of the bag filter:
所以說一般情況下，布袋除塵器在使用中突然出現(xiàn)冒煙塵的現(xiàn)象，我們要及時停止除塵器的運行，馬上進行停機檢修。冒煙塵的主要原因之一就是破袋引起的。除塵濾袋是逐漸磨損的，引起磨損的主要原因是粉塵的磨削力，高溫引起的布袋變質(zhì)和化學(xué)物質(zhì)的腐蝕，當粉塵的磨削力很強時，除塵布袋底部磨損最嚴重，系統(tǒng)容量的增加引起過濾速度增高也能加速磨損。
So the general situation, the use of bag filter in the case of the sudden emergence of smoke, we want to stop the operation of the dust remover, and immediately stop maintenance. One of the main reasons for the smoke is caused by a broken bag. Dust filter bag is gradually wear, the main causes of the wear is the grinding force of the dust, corrosion caused by high temperature bag modification and chemical substances, when the dust of the grinding force is very strong, the dust bag bottom wear the most serious, system capacity increase cause the filtration rate increased to accelerate the wear and tear.
