Abstract
The utility model discloses a filter cartridge used on a filter cartridge type dust collector. The adopted technical scheme is as follows: the filter cartridge used on the filter cartridge type dust collector is characterized in that the filter cartridge comprises a top cover, a base and a cylinder, wherein the cylinder comprises a cylinder inner core and a cylinder outer layer, the cylinder inner core is a metal net rack, the cylinder outer layer is a filter material, and the filter material is a folded filter material which is formed by weaving superfine metal wires three-dimensionally. The metal filter cartridge is formed by weaving the superfine metal wires three-dimensionally, and has controllable filtering aperture, strong air permeability, reasonable corrugated depth, resistance to knocking, high bursting strength, electric and magnetic conduction, high filtering efficiency and dust removal efficiency, reliability in running, economy and convenience. The cylinder outer layer of the folded filter cartridge forms a creased type structure after being folded. Compared with a common filter cartridge, the effective filtering area can be improved by four times, and the treated air volume is greatly increased.
Description
Technical field
The utility model relates to a kind of dust arrester, especially relates to a kind of filter cylinder that is used on the filter drum type precipitator.
Background technology
Filter drum type precipitator just occurred in Japan and more American-European countries as far back as the seventies in 20th century, it is little to have volume, the efficient height, reduced investment, advantages such as easy care, but because of its place capacity little, difficulty is combined into big air quantity equipment, and filtration velocity is on the low side, and range of application is narrow, so only in sector applications such as grain, welding, fail large-scale popularization for many years.In recent years, along with new technology, new material constantly develop, company with Japan, the U.S. is representative, structure and filtrate to deduster improve, make filter cartridge dust remover be widely used in industrial circles such as cement, iron and steel, electric power, food, metallurgy, chemical industry, whole volume increases several times, becomes filter area＞2000m
2Large-scale deduster (GB6719-86 class), be solve traditional deduster to ultrafine dust collect difficult, filtration velocity is high, ash-removal effect is poor, filter bag run-down, preferred plan that operating cost is high easy to wear.
Filter cylinder is the vitals on the filter drum type precipitator, common filter cylinder material is weave cotton cloth filtrate and coated filter material, wherein, the dust removal mechanism of filtrate of weaving cotton cloth is when dusty gas during by filtrate, the effects such as sieving, interception, collision, diffusion and electrostatic attraction of main dependence fiber on filtrate, form the dust bonding layer with the dust detention, before stable bonding layer forms, the efficiency of dust collection of filtrate is not high, has only 50%～80% usually.Continuous increase along with dust thickness, SR constantly increases, just need periodically deashing this moment, the process of deashing can be destroyed dust layer again, before forming new dust bonding layer, efficiency of dust collection can reduce again greatly, therefore, uses the efficiency of dust collection of the deduster of this kind filtrate to have cyclic fluctuation; Simultaneously purging repeatedly frequently rubs filter cloth and skeleton, causes cloth bag to damage, and dust laden air leaks, and makes the air after the processing not reach discharge standard, therefore is difficult to the total dust removing effects of assurance.And coated filter material or filter paper are to be covered with the thin layer that one deck has minute aperture on filtrate base fabric surface, its effect is equivalent to dust bonding layer above-mentioned, filtration this layer film that places one's entire reliance upon, also reduce SR during deashing and can not destroy this layer film, therefore dust removing effects is stable, but still can not change the problem that makes filter bag damage owing to the effect of blowback wind, and because the coated filter material price will be higher than far away and weave cotton cloth and needle punched filter material, its use also is restricted.
Summary of the invention
The purpose of this utility model is to provide the filter cylinder on the deduster of being used for of a kind of long service life, good dedusting effect, its technical scheme is: a kind of filter cylinder that is used on the filter drum type precipitator, it is characterized in that: described filter cylinder comprises top cover, base and cylindrical shell, described cylindrical shell comprises cylindrical shell inner core and cylindrical shell skin, described cylindrical shell inner core is a metal truss, and described cylindrical shell skin is a filtrate.
The technical solution of the utility model also has: described filtrate is to be formed by superfine metal silk 3 D weaving.
The technical solution of the utility model also has: described filtrate is the filtrate that folds.
The advantage of this kind filter cylinder is:
1. utilize superfine metal silk 3 D weaving to become pleated filter cartridge, this metal filter cylinder pore size filter is controlled, and gas permeability is strong, and the corrugation degree of depth is reasonable, is not afraid of and collides with, and bursting strength is strong, conductive magneto-conductive, and the filter efficiency height, the efficiency of dust collection height, reliable, economical convenient.
2. the cylindrical shell of pleated filter cartridge is outer compares with common filter cylinder through being folded to form pleat formula structure, and effective filtration area can improve 4 times, handles air quantity and improves greatly;
3. the filter cylinder of pleat formula structure adopts integrated structure design, has substituted filter bag and cage bone in the conventional bag deduster, makes that the installation of filter part is very easy, and the workload when having significantly reduced each the replacing reduces the off-time;
4. the pleat formula skin of filter cylinder can be combined closely with wire netting, significant sealing affection, thus guarantee that deduster outlet dust emission concentration is extremely low.
Description of drawings
Accompanying drawing 1 is the structural representation of this filter cylinder, and accompanying drawing 2 is the structural representations that adopt the filter drum type precipitator of this filter cylinder, wherein, the 1st, deduster housing, the 2nd, soot cleaning system, the 3rd, filter cylinder, the 4th, ash bucket, the 5th, support, the 6th, air inlet, the 7th, air outlet, the 8th, push-pull valve, the 9th, deflector, the 10th, connect the ash tube, the 11st, base, the 12nd, top cover, the 13rd, cylindrical shell inner core, the 14th, cylindrical shell skin.
The specific embodiment
In conjunction with the accompanying drawings, the utility model discloses a kind of filter cylinder that is used on the filter drum type precipitator, this filter cylinder 3 has comprised base 11, top cover 12 and cylindrical shell, cylindrical shell has comprised cylindrical shell inner core 13 and cylindrical shell skin 14, and cylindrical shell inner core 13 is made by wire netting, has played supporting role, cylindrical shell outer 14 and the 13 coaxial installations of cylindrical shell inner core, the filtrate of cylindrical shell skin 14 is formed by the wire 3 D weaving, and wire diameter is 14-46 μ m, calculated length after, filtrate is folded into pleat, and head and the tail are bonded.
