(3) summary of the invention:

Technical problem to be solved in the utility model: according to present medium-sized and small enterprises of China and also not loose present situation and the environmental issue anxious to be solved of private enterprise's economy, the utility model designs and manufactures a kind of wide application, multipurpose, can smoke abatement and dust control in hot environment, can be applicable to the smoke-eliminating purifying of other pernicious gas again, reach the purpose of small investment, instant effect.

The technical scheme that solves the problems of the technologies described above: design a kind of high temperature resistant filtering type smoke purifier, it comprises filter grid, it is characterized in that in the casing of smoke purifier, the parallel drawer type filter grid that to substitute at any time that is equipped with in the air inlet both sides, its drawer type filter grid is by flat framework, borrow flat frame to be shaped on the blind window of a fixed inclination upward opening on this framework formed two big planes, the particulate filter layer of filtering smoke is housed between the space on the flat framework between the two parallel blind windows, the upper end of two parallel filter grids is shaped on top cover, parallel drawer type filter grid with two of top cover and bottom dust collecting box form the gas medium chamber, and the upper end of casing is shaped on clean gas outlet.

The utility model compared with prior art, its beneficial effect: 1. owing to the particulate filter layer in the middle of the drawer type filter grid has adopted the potter's clay of high alumina matter and added swelling agent, the particle filter course of at high temperature making, the filter material specific grain surface long-pending near or reach the specific area 700～1200m of activated carbon ²/ g, thus the smoke-eliminating purifying ability of adsorbing black smoke improved; 2. because filter grid is designed to drawer type, can open hermatic door at any time and from casing, extract out according to the character of Purge gas, change the drawer type filter grid of the filter course of suiting the medicine to the illness, owing to be convenient to extract out, greatly facilitate and clean and maintenance simultaneously, improve the maintenance condition, guaranteed the normal operation of equipment; 3. because uniform porous water-spraying or the blower of row's one determining deviation is housed between drawer type filter grid two blind windows, made things convenient for the cleaning renovation of particle filter course has been used; 4. because the filter course in the drawer type filter grid adopts high alumina matter particle filter course, it is not only applicable to 1000 ℃ high-temperature gas, filtration velocity can reach 0.5～0.7m/s simultaneously, has improved 10 times than sack cleaner filtration velocity, greatly reduces cleaner investment and floor space; 5. compare with electrostatic precipitator, the small investment power consumptive province changes voltage instability simultaneously, and this machine operation is had no effect, and has guaranteed the safety smoke eliminating udst separation.6. because the filter grid filter material can be equipped with arbitrarily by the requirement of filtering gas medium, enlarged range of application of the present utility model greatly.
