Cartridge filter with small size and high efficiency. Since the emergence of a new filter and filter design improvements, cartridge filter dust project to start in the application.

  1, cartridge construction Cartridge filter is a cartridge filter element, cartridge into the construction of roof, metal framework, such as fold-shaped filter and the base part 4.

  Cartridge is designed to fold into a pleated filter length, end to end sticky synthetic tube; tube with a metal frame support inside and outside, up and down with the cover and base, fixed, fixed roof bolts and washers. Round performance and form factor cartridge shown in Figure.

  2, filter structure Dust from the inlet pipe, exhaust pipes, boxes, ash bucket, cleaning device, cartridge, and the composition of electronic control devices.

  Filter cartridge in the layout is very important, cartridge box vertically arranged flowers in the board, you can tilt the board in the flower arrangement, bolted, and loved a rubber pad; take part under the plate filter room, on the part of the net chamber. Cartridge in addition to fixed with bolts, the more convenient way is to automatically locking device and rubber compression devices, these two methods is very convenient for the installation and maintenance.

  3, cartridge filter works Dust into the dust collector hopper gas, due to sudden expansion of air section, air flow part of the coarse dust particles and the inertial force of gravity down under the settlement, fine grain size, density of dust particles into the filter chamber After sifting through the Brownian diffusion and the combined effect of such, so that dust deposited on the filter surface, purified gas into the chamber from the exhaust pipe of the net through the wind

  Machine discharge. Resistance cartridge filter with the filter surface dust layer thickness increases, resistance to a specified value, for cleaning, then pulsed electromagnetic pulse valve control device controls the opening and closing. When the pulse valve is opened, compressed air within the air bag valve through the pulse tube by blowing a stream of jet holes on the high-speed, high-pressure injector flow, thus forming an equal volume of injector flow induced by 1 to 2 times defect flow together into the cartridge, the cartridge inside a moment to create positive pressure and bulging and micro; deposited dust on the filter off, fall into the ash bucket, ash bucket through the dust discharge, continuous discharge.

  This pulse cleaning method, is ranked by order of cleaning cartridge, pulse valve opening and closing time to generate a pulse action, the time required for the 0.1 ~ 0.2s; pulse valve opening and closing of two adjacent interval time is 1 ~ 2min, to complete a full cartridge cleaning cycle time is 10 ~ 30min. As for the low-pressure pulse cleaning of the equipment, so the situation under the resistance of the device, should be appropriately extended injection time, and the injection interval and injection cycles appropriate to shorten.

  4, the characteristics of cartridge filter
Cartridge filter and the following features:
fold as filter pack to use, layout density, dust collector, compact structure, small size, filter material to toughness.

  cartridge height is small, easy installation, use and maintenance workload of the small;
Dust filter with an area of relatively large size, filtration velocity smaller, less resistance;
filter seal off both ends of fold required strict, can not have leaks, otherwise it will reduce the results.

  5, DFL-type cartridge filter performance DFL Series cartridge dust device as long, cartridge from the top of the vertical installation, for the effect of high concentrations of dust removal is preferred.

  Upper outlet into the dust stream from the popular box, through the baffle to flow evenly to the filter element, under the action of the filter elements, filter elements dust be attracted to the surface, in contact with the net export of gas through the exhaust pipe , pulse valve under the control of the controller, turn on the filter element for cleaning; as filter elements vertical installation, you can ensure good cleaning effect.
