Description
Technical field
The utility model relates to filtration arts, in particular to inward flow filtration-type filter device.
Background technique
It is applied to the adverse circumstances such as high temperature and pressure and strong corrosive such as ceramic industry, metallurgy, coal chemical industry, thermal power generation at present
In the filter core that is separated by filtration admittedly of gas solid, liquid mainly have following two major classes:
One, using cloth or flexible metal film as the flexible filter core of representative, filter material is fabricated to filter bag, filter bag is generally justified
Shape, it is closed at one end open at one end；In bag the dedicated frame of adapted carry out using.Frame generally uses cage, by several longitudinal directions
Metal round bar, circumferential metal ring and the buckle of opening and the back cover of bottom be welded, frame is generally placed in bag,
Mainly play a part of to support cloth bag.
Such filter core filter material thinner thickness, air flux is larger, but the structural strength of filter core is lower, can not be applicable in high pressure blowback
Operating condition is cleaned, therefore its self-cleaning effect is poor, filter core easily blocks failure.
Two, using ceramic element as the rigid filter core of representative, filter material is fabricated to chimney filter, it is closed at one end open at one end, it adopts
With substrate and filter membrane monoblock type；Such filter core is to guarantee its structural strength, and thickness is generally thicker, and air flux is smaller.
The filter type of above-mentioned two classes filter core is mainly outside filtering type, i.e., dusty gas through filter bag outer surface filtering after,
Dust is blocked on the outer surface of filter core, and automatically cleaning relies primarily on blowback realization, effect by filter cartridge construction intensity and
The limitation of many factors such as blowback air pressure.There are a small number of inward flow filtration-type filter cores for using cloth bag as filtering material currently on the market, makes
With in the process, because the characteristic of cloth result in environment temperature be more than 200 DEG C, under bad working environments when be not available or functional performance
It reduces.
