Abstract
The utility model discloses a piece of glass fiber needled filter felt which comprises base cloth layers. The glass fiber needled filter felt is characterized in that a glass fiber cloth surface layer is installed on the upper side of the base cloth layers, a glass fiber cloth bottom layer is installed on the lower side of the base cloth layers, the base cloth layer is knitted through warps or wefts, fibers mixed by glass fibers and synthetic fibers are utilized as the warps or the wefts, the base cloth layers are three layers, the base cloth layers are connected with one another through adhesion agents, the base cloth layers are connected with the glass fiber cloth surface layer through adhesion agents, and the base cloth layers are connected with the glass fiber cloth bottom layer through adhesion agents. The glass fiber needled filter felt has the advantages of being good in thermal stability, good in resistance to chemical gas corrosion, good in oxidation resistance, good in filtering accuracy, superior in temperature resistance, and high in tensile strength, utilizing surface filtration to achieve good stripping performance of dust, enabling ash to be removed easily, reducing dust removing frequency of a dust remover, and prolonging the service life of filter material.
Description
Technical field
The utility model relates to the fibre field, relates in particular to a kind of glass fibre needled filtering felt.
Background technology
At present, in some occasions that the filtrating smoke dust temperature is higher, smoke components has more complicated, filtering material such as uses such as iron-smelter, garbage burning factory, blast furnace gas length, the temperature of particle is higher, to filtering material heat endurance, chemically-resistant gas attack and filtering accuracy have relatively high expectations.The filtering material that now uses, the heat endurance of product, chemically-resistant gas attack, filtering accuracy are relatively poor, and resistance to elevated temperatures is poor, and service life is short, draws thus common filtering material and is difficult to satisfy its requirement.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in the prior art.
Summary of the invention
The purpose of this utility model provides a kind of glass fibre needled filtering felt.
The technical solution adopted in the utility model is:
A kind of glass fibre needled filtering felt comprises base cloth layer, it is characterized in that: the upside of described base cloth layer is provided with the glass fibre cloth cover, and the downside of described base cloth layer is provided with the glass fabric bottom.
Described base cloth layer is to do the braiding of warp thread or weft yarn by glass fibre and the mixed fiber of synthetic fibers to form.
The number of plies of described base cloth layer is one deck.
The number of plies of described base cloth layer is the 2-5 layer.
Between described base cloth layer and the glass fibre cloth cover, all be connected by adhesive between base cloth layer and the glass fabric bottom.
Between described base cloth layer and the base cloth layer, between base cloth layer and the glass fibre cloth cover, all be connected by adhesive between base cloth layer and the glass fabric bottom.
The utility model has the advantages that: Heat stability is good, the chemically-resistant gas attack is good, good in oxidation resistance, filtering accuracy is high, temperature tolerance is superior, and hot strength is high, adopts surface filtration, and the stripping performance of dust is good, easy-to-clean ash, the deashing frequency of reduction deduster, the service life of having improved filtrate.
