1, Cartridge filter Structure Structure of cartridge filter into the air from the pipe, exhaust pipes, boxes, ash bucket, cleaning devices, diversion devices, flow distribution distribution board, cartridge, and the composition of electronic control devices, similar to the gas tank Pulse Bag dust structure.
Filter cartridge in the layout is very important to both the vertical arrangement of flowers in the box board, you can tilt the board in the flower arrangement, from the cleaning effect, the vertical layout is more reasonable. The lower part of the filter chamber flower plate, the upper chamber for the air box pulse. In the dust with air distribution plate at the entrance.
II cartridge filter works Dust into the dust collector hopper gas, due to sudden expansion air flow section and the role of air distribution plate, a part of coarse particles in the air and the inertia effect of moving the settlement in the ash bucket; fine grain size, density of dust particles After entering Dust room, sifting through the Brownian diffusion and the effects of such combination, so that dust deposited on the filter surface, the purified gas into the net from the exhaust gas chamber through exhaust fans.
Resistance cartridge filter with the filter surface dust layer thickness increases. Resistance to a specified value for cleaning. PLC program control valve pulse time off, the first sub-chamber to enhance a valve closed, the air filter cut off, and electromagnetic pulse valve is opened, compressed air and the short time the rapid expansion in the cabinets, the influx of cartridge to cartridge expansion and deformation vibration, and erosion under the action of reverse flow, attached to the outer surface of the dust bag is stripped of falling into the hopper. After cleaning, the electromagnetic pulse valve is closed, improve valve open, the chamber resumed filter status. Cleaning each room in turn, starting from the first room to the next cleaning cleaning start a cleaning cycle. Falling within the dust fall into hopper by? Ash discharge valve.
3, the company's technology to improve
1. Cleaning devices Traditional cleaning cartridge filter, there are two methods for a high-pressure air cleaning, one is a pulse air injection, practice shows that the former has the advantage of uniform flow, gross consumption of large disadvantage; the latter the advantage of low air consumption, air drawback is weak. this can be used both to improve: on the one hand increase in pulse jet pipe diversion device to enhance air flow induced m the other hand, the cartridge upper diversion duct cancel m induced flow to pulse flow and fully into the cartridge while, so that less air consumption improved flow uniformity m m m calculated effective cleaning m technology improved gas pulse cleaning air flow is 3-5 times
2. Gas distribution plate Cartridge dust collector air distribution is very important to consider how to avoid the device m the entrance as high winds caused the high wear areas on the filter, air distribution plate for the cartridge filter has a unique air distribution required to be m very stable and uniform. Be conducive to the rise in air and dust in the air distribution plate m down 35% open porosity, calculated m drag coefficient
3. Cartridge and filter media Cartridge is calculating the length of pleated filter material folded into a cylinder m m sum of bonding metal cylinder of the internal frame support *** m the upper and lower lid and base with a fixed filter length the nature of the dust and the concentration of dust decision
Filter is the core of the cartridge filter, cartridge filter is the key to the success of the last m are generally used to filter this filter fiber filter paper page on the> 0.5um the dust has> 99.9 % filtration efficiency of m but the disadvantage is that large dust capacity, cleaning difficulties should not be used for high concentration of ambition Co., Ltd. of Japan produced in 2000 with its own intellectual property? continued long-fiber filter to solve the above problems existing in the filter market m filter bags with acupuncture it was this deep filter made of filter material m Bag In the early work required on the surface of a primary dust cake. Dust easily through increased emissions of such filter m m m or blocking the air passage so that premature bag failure. Especially in the collection of dust with a damp paste is easier when m bags. The ambition filter has the following characteristics: The filter is usually
1 m deep filter it depends on the filter surface to effectively filter dust layer m to establish an effective filter for about 10% of the entire filtration process. N the surface of filter membrane filter media is no dust filter through into the first filter n no n the beginning of close to 100% of the effective filter 2, the conventional filter material in high concentration after the dust into the air permeability down n up n m coated filter resistance with uniform pore size and fine material is not put into use immediately after the viscosity n to provide excellent filtration of dust transmittance near zero n n n resistance are stable in the filtration rate by testing its resistance around 1-2m/min condition n for the 300-500Pam
