Abstract
The utility model discloses a piece of improved glass fiber needled filter felt which comprises a base cloth layer. The improved glass fiber needled filter felt is characterized in that a gel coat is installed on the upper side of the base cloth layer, a glass fiber yarn layer is installed at the bottom of the base cloth layer, the base cloth layer is glass fiber checked cloth, and the gel coat is a nano gel coat. The improved 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 improved 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 improved glass fibre needled filtering felt.
The technical solution adopted in the utility model is:
A kind of improved glass fibre needled filtering felt comprises base cloth layer, and the upside of described base cloth layer is provided with gel coat, and the bottom of described base cloth layer is provided with the glass fiber yarn ring layer.
Described base cloth layer is the glass fibre woven roving.
Described gel coat is the nanometer gel coat.
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.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, base cloth layer, 2, gel coat, 3, the glass fiber yarn ring layer.
The specific embodiment
