Abstract
The utility model discloses a piece of glass fibre woven filter cloth for filtering shaft kiln cement, which comprises glass fibre wefts, glass fibre wraps and expanded glass fibre wefts. The woven filter cloth is made up by the wefts and the wraps which are straightened and put in certain arrangement. Each wrap of the upper layer of the filter cloth is crossed with each weft of the upper layer of the filter cloth, and the distance between every two adjacent wraps is equal. The wefts of the upper layer of the woven filter cloth are glass fibre yarns, the wefts at the lower layer of the filter cloth are expanded glass fibre wefts, and the wefts are interwove with the wraps to form a piece of dual composite woven filter cloth. The glass fibre woven filter cloth has good condensation resistance, flexure resistance and alkali resistance, good hydrophobic property and good dust removal performance, and the filter cloth is low in power consumption when removing the dust, easy to clean the dust, small in resistance and good in dust collecting effect, with the dust collecting efficiency reaching above 99 percent. The shrinkage rate of the fibre under service temperature is zero and the filtration efficiency can reach above 99.5 percent. The glass fibre woven filter cloth is stable and good in ventilation property and can remarkably improve the ventilation condition.
Description
Technical field
The utility model relates to a kind of gas filtration dedusting filter bag that cement industry uses, particularly a kind of shaft kiln cement glass fibre woven filter cloth of being applied to.
Background technology
Cement industry be adopt glass fiber filter material the earliest, one of maximum industry.Kiln hood, kiln tail adopt sack cleaner more.Kiln tail sack cleaner great majority adopt the glass coated filter material.In the shaft kiln kiln tail dedusting in medium and small cement plant, the dryer dedusting, flue-gas temperature and humidity are all than higher, usually adopt the woven filtrate of glass, existing filtrate that cement in vertical kiln is used is most to be plain weave or single twill, though it has the air-flow Air permenbility big, process advantages such as simple, but also there are some problems in it, for example: oblique pulling causes bag because of external force is easily out of shape, special circumstances reach drawbacks such as discharge standard, Bag structure easily crack because of the too little difficulty of dust granules for a short time.
Summary of the invention
For solving the shortcoming that exists in the prior art, the utility model provides a kind of granule dust that both had been easy to discharge, and also can not make bag use woven cloth filter cloth because of external force glass fibre shaft kiln cement out of shape.
The technical solution of the utility model is achieved in that glass fibre shaft kiln cement application woven filter cloth, comprising: glass fibre weft yarn, glass fiber warps, glass fiber bulk strand weft yarn, and this woven filter cloth stretches arrangement by warp, parallel; Every warp thread of top one deck of this filter cloth all has with every weft yarn and intersects, and the distance between every warp thread equates; The upper layer weft yarns of this woven filter cloth is a glass fiber yarn, and lower floor's weft yarn is a bulked glass yarn, and weft yarn is woven into dual composite construction woven filter cloth with the warp thread structure respectively.
The beneficial effects of the utility model are: have the resistive connection property revealed, flexible resistance and alkali resistance preferably.Hydrophobic performance is good, and dust peeling property is good, makes the deashing energy consumption low, and easy-to-clean ash, resistance are little, and dust collection effect is good, and dust-collecting efficiency reaches more than 99%.The shrinkage factor of fiber itself is zero under serviceability temperature, and filter efficiency can reach more than 99.5%; Gas permeability is stablized greatly, can significantly improve ventilation condition.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The glass fibre shaft kiln cement is used woven filter cloth, comprising: glass fibre weft yarn 1, glass fiber warps 2, glass fiber bulk strand weft yarn 3, and this woven filter cloth stretches arrangement by warp, parallel; Every warp thread of top one deck of this filter cloth all has with every weft yarn and intersects, and the distance between every warp thread equates; The upper layer weft yarns of this woven filter cloth is a glass fiber yarn, and lower floor's weft yarn is a bulked glass yarn, and weft yarn is woven into dual composite construction woven filter cloth with the warp thread structure respectively.
Because warp, the parallel of this fabric stretch arrangement, do not have crimp (claiming curved contracting again), thereby the strength efficiency of fiber promptly to knit behind the fabric into the strength retention of fiber very high, and the dimensional stability of fabric is good.This kind filtrate covering power is strong, good permeability, and intensity is big, thereby can improve filter efficiency, reduces filtration resistance, and the efficiency of dust collection height, can reach more than 99.6%, and the rate of filtration is at 0.8～1.0 meter/minute.
