DDF large anti-hair bag filter

DDF large anti-hair-bag filter is to protect the operator and the people of physical and mental health, the growth of crops, machinery and equipment wear and tear, recycling dust pollution and useful social environment to reduce the effective cost of equipment; inlet temperature 729 and 734 polyester fabric temperature <1500 ℃; after three generations treated glass fiber cloth temperature <3000 ℃. DDF large anti-hair-bag filter is widely used in steel mills, smelters, cement, carbon black plants, power plants and other enterprises smelting, crushing, screening and combustion of soot produced by purification and recycling. Large anti-hair baghouse structure of DDF: First, dust bag attached to the increasing resistance increases the predetermined value, that is the beginning of cleaning. Two, DDF large-scale anti-hair bag filter cleaning methods rely on single-chamber anti-hair way, when the anti-hair through the valve, close the exhaust pipe, open the anti-hair tube, cut off the single-chamber exhaust. Third, because the equipment of each chamber inlet pipe is the same, but are in a negative state, due to the negative pressure suction effect next room, so that the air flow is drawn through the anti-hair bag chamber pipe, through the bag, the air from the outside into the inside of the bag, the hopper and the chamber inlet pipe and exhaust inhalation neighboring room, then deflated bag sucked. Four, followed by dust inside the bag and shake off the sink to drop heavy ash bucket, complete single-chamber cleaning, cleaning rest rooms under the control of the implementing agencies, were cleaning the same order, in addition to a certain value when cleaning is stopped. DDF large anti-hair-bag filter works: DDF large anti-hair baghouse points positive pressure (also known as push-in) and negative pressure (also known as inhaled), dust-laden air under negative pressure from the intake duct into the next hopper in front of the inlet has a spoiler, carom and coarse dust by gravity fall into the hopper, fine particles of dust bag after filtration, adsorption on the inner wall of the bag, clean After the gas through the baghouse, the top of the device through the switching valve suction fan through a discharge pipe, and then the exhaust pipe into the atmosphere. Dust bag attached increasing resistance rises to a predetermined value, which began cleaning. Cleaning equipment by way of a single-chamber anti-hair way, when the anti-hair through the valve, close the exhaust pipe, open the anti-hair tube, cut off the single-chamber exhaust. Because the device inlet duct of each room is the same, but are in a negative state, due to the negative pressure of the suction effect next room. The flow of air is sucked through a reverse air bag chamber pipe through the bag, the air from the outside into the inside of the bag, the hopper and the chamber inlet pipe and exhaust inhalation neighboring room, then deflated bag sucked. Inside the bag and shake off the dust to the dust accompanied by the pressure drop ash bucket, complete single-chamber cleaning, cleaning rest rooms under the control of the implementing agencies, were cleaning the same order, in addition to a certain value, cleaning stops.
