Baghouse outlet of “risk ash” There are two cases, one is the continuous “gray risk” that seriously damaged due to the dust bag, the bag is not strong binding off, or up and down the bag filter is not tight mouth hanging, hanging port and flower plate, connecting plate and flower flower plate imprecision caused by leakage of dust. Another is the moment “to take ash”, this situation is a dust filter bag, although damaged, but less severe, momentary “adventurous ash” when baghouse blow. When looking baghouse “take the gray” reasons, according to the outlet “take ash” with the electromagnetic pulse valve, pulse controller operation corresponding to the number of bits used to determine which exclude dust bag dust leakage. On Uncovery bag filter can also be observed from the housing hole isolated leak dust filter bag with a flashlight; or open the lid and then open exposing pulse control device, which was found from the venturi “take ash” in the injection process , is that the dust bag dust leakage. Then, depending on the problems treated. Replacing the dust bag when the bag filter, analyze it to check the damage causes. Dust bag life factors are the nature of the dust, the distribution, the processing quality airflow Dust skeleton and the like. As a result of the filter bag frame welding is not strong, open in the course of the welding process, the dust bag pierced, it is timely to weld and dust skeleton hair Thorn lighting polished welding slag, dust or renewal of the skeleton. Bag skeleton usually with a diameter of 4 mm welding wire made of. There are two commonly used welding method is to use spot welding spot welding, and the other is with oxygen – acetylene welding. Using the former method, high production efficiency, smooth surface, easy to produce burr, small deformation. With a method, low productivity, rough surface, easy deformation. In addition, the plastic frame, but the framework does not Suitable for use at high temperatures. In the injection process, due to the cleaning time for each bag, the friction with the outer surface of the first frame dust, so dust bag used after a certain time, although not damaged, but the inner surface of the frame in contact with the dust removing section Bit has been worn, when the refill according to the original signs of wear parts staggered in order to avoid further wear in place, so that prolong the life of the dust bag. When you install baghouse filter bag framework of the Uncovery pulse dust collector should pay attention to remove fouling perforated plate clean to prevent the interface between the porous plate is not caused by leak tight, affecting the purification efficiency; To blow hole quasi venturi center to ensure blowing results. Open the door and down the opposite side to pay attention to dust hanging elastic mouth properly, so that the next mouth hanging off bad threads and tighten. When the dust bag removal installation be careful not to collide with the baghouse metal edges and corners to prevent internal injury.
