XLMC type submerged - flow filter cartridge filter

　　The structure of filter cartridge dust collector is composed of air inlet pipe, air exhaust pipe, box, ash bucket, ash cleaning device, diversion device, air flow distributing plate, filter barrel and electric control device. It has the characteristics of reasonable structure, high dust removal efficiency, strong practicality, small floor space and remarkable energy-saving effect. Applicable to all kinds of dry dust, such as tobacco, steel, cement, pharmaceutical, sand blasting, casting, rubber, carbon black and other industries. The special filter can also be used in plastics, dyes, resins, starch, coal ash and other industries that require antistatic. In addition for some very small diameter dust also has a special filter material can be used.

　　I Working Principle

　　After the dust containing gas enters the dust hopper, due to the sudden expansion of the airflow section and the action of the airflow distribution plate, a part of the coarse particles in the airflow settle in the dust hopper under the action of dynamic and inertial forces. After entering the filter chamber, dust particles with fine particle size and small density are deposited on the surface of the filter material through brown diffusion and screening, and the purified gas enters the clean air chamber and is discharged by the exhaust pipe and fan. The resistance of cartridge filter increases with the increase of dust layer thickness. Ash removal occurs when the resistance reaches a specified value. At this time, the PLC program controls the opening and closing of the pulse valve. When the pulse valve is opened, the compressed air in the air bag enters into the filter cartridge uniformly through the venturi tube, which causes the expansion and deformation of the filter cartridge to produce vibration. And under the effect of the reverse airflow washing, the dust attached to the outer surface of the filter bag is stripped off and falls into the ash bucket. The collected dust is discharged into the ash bucket through the ash discharge valve.

　　Two performance characteristics

　　1, the use of advanced sink flow layout and filter barrel inclined structure, so the dust collector in the process of work synchronous cleaning effect.

　　2. Dust baffle plate is set at the dust gas inlet, which has buffering and wear resistance effect, avoiding the dust directly impacting the filter cartridge at high speed, thus extending the service life of the filter cartridge.

　　3, the filter cartridge 15° inclined drawer-type installation, can make the filter cartridge dismantlement more convenient, moreover the dust collector body does not have the transmission part, causes its maintenance work to reduce to the minimum. For ordinary dust, the filter cartridge can be used for a long time without replacement, which saves the tedious work of frequently changing and washing the filter bag for the common bag filter, and saves a lot of maintenance cost.

　　4. Modular assembly structure combination, not picky about installation space environment.

　　5, can expand the original combination, increase the dust removal unit and treatment of air volume, and do not need to make too many changes to the original equipment.

　　XLMC filter cartridge performance parameters table

　　Note: The standard configuration of this type of dust remover is the ordinary polyester filter cartridge. The dust collection capacity of over 5 microns is 99.5%. The recommended filter wind speed is 0.8-1.2m/min.

　　According to the requirements of customers and on-site mines, we can choose the following filter materials: flame retardant composite fiber filter material, flame retardant treatment polyester fiber, oil proof and waterproof treatment polyester fiber, anti-static treatment polyester fiber, film coated polyester fiber and a variety of characteristics of filter materials.

　　Under the condition of the same filtration area and treated air volume, its volume is only 1/4 of the bag filter, and its price is only 80-90% of the bag filter. For dust filter is more than 3 um, efficiency can reach 99.99%, close to zero emissions, because of its small volume, light weight, corrosion resistance, viscous resistance, antistatic, high efficiency, simple management, and the advantages of convenient maintenance, installation, flexible, widely used in the high temperature of all kinds of dust pollution, it will gradually become the replacement of the cloth bag dust collector.
