What are the causes and treatment methods of smoke and ash of cloth bag duster?

Date of release:2018-05-14 Author: Click:

Mine bag precipitator emit smoke of Posting key location: popular condition, mining royalty - appear in the application of bag filter to risk a sign of soot, let's be real time interrupt operation of filters, interruption outage inspection immediately. One of the most important warnings about smoking is a broken bag. Dust filter bag is slowly wear, causing wear dust are the important notice of grinding force, low temperature caused by bag evolution and chemical decay, when the dust of the grinding force is very strong, wear the worst at the bottom of the dust bag, increased system capacity caused the growth of filtration rate can also speed up the wear and tear.

Mine bag dust collector outlet state of "smoke" have two kinds, one is "smoke", namely because dust filter bag, filter bag, tie rickety sparse perhaps mine bag precipitator hanging mouth is not rigorous, hanging mouth and flowers plate plate, and the cohesion between the flower board not rigorous and leakage of dust. The other is "smoke and dust" in a split second. This state is that although the dust filter bag is damaged, it is not very important.

Because when large areas of dust filter bag damage, should break all the replacement, replacement of dust bag the most interrupt interrupted when things, thanks to filter the dust control device should be closed, opening at the top of the manhole door, can bag assembly, assembly, the first bag cage will be taken into, and then to bag a flowing spring coil pinched into concave, pull up dust bag, new bag before assembly, should clean up the dust on the plate hole.

When replacing the dust filter bag with the dust filter bag, the damage notice should be analyzed. The factors that influence the life of the dust filter bag include the properties of dust, the distribution of air flow, the processing quality of dust removal framework, etc. As a result of filter bag frame welding not firm, in the application process of welding, cheng will be the dust filter bag might break, should be good real-time welding, and dust removal skeleton burr welding slag grinding polishing, may change into a new frame of dust. The frame of the filter bag is usually welded with steel wire 4 mm in diameter. There are two kinds of welding methods commonly used, one is spot welding with spot welding machine, the other is oxygen - acetylene welding. Using the former method, high cost efficiency, smooth surface, not easy to occur burrs, small deformation. The dust precipitator is not as good as the application of the damaged dust bag to interrupt the work, otherwise it will speed up the dust precipitator scrap. When individuals dust bag ignition small damage occurs, in order to saving cost, suggest to use the old bag or different materials, application of new filter cloth will hole up, interrupt method fill hole is to use the inorganic silicon rubber mixture of adhesive, as long as the bonding agent application function and process temperature, chemical environment. Adopt the latter method, low cost efficiency, rough surface, easy deformation. Others have adopted plastic frames, but they are not suitable for low temperatures. In blowing process, because of the filter bag every cleaning, will work with the friction surface dusting framework surface once, so the dust filter bag after application to a certain time, although not destroyed, but its surface fought with dust removal framework parts for wear and tear, reload according to wear things will originally part of the staggered, to avoid the in situ inheritance wear, so much can life extends the application of dust filter bag.

Find mine bag dust catcher "smoke" take notice, according to the outlet "emit smoke" with electromagnetic pulse valve, the pulse control meter measures corresponding digits to discrimination is on the other side of the dust filter bag dust leakage. The upper cover mine bag filter can also use a flashlight to detect the leakage dust filter bag from the observation hole of the upper box body. Or open the upper cover and then open the pulse control device, in the process of blowing the invention from which Venn pipe "smoke", is which dust filter bag leakage. Then, according to the results of the interrupt processing. Because when most of the dust filter bag damage, should break all the replacement, replacement of dust bag the most interrupt interrupted when things, thanks to filter the dust control device should be closed, opening at the top of the manhole door, can bag assembly, assembly, bag cage take in first, then to bag a flowing spring coil pinched into concave, pull up dust bag, new bag before assembly, should clean up the dust on the plate hole.

Skeleton assembly mine bag dust collector filter bag, be steady hand to peel on impulse precipitator dust removal on the perforated plate is clean, in case of interface between the porous plate and not rigorous air leakage, affect pollution effect; The blowpipe hole should be aimed at the center of the venturi tube to cover the blow-out. The duster of opposite side door should hold steady high and low hanging mouth to suit firmly, in case the bottom hanging mouth is too few and screw out the rib.

When the dust bag is assembled and assembled, it should be ensured that it does not collide with the metal edges and corners of the mine dust bag filter to prevent hidden damage.
