Glass fiber composite filter material for methanol filters

Abstract

The invention discloses a glass fiber composite filter material for methanol filters. The glass fiber composite filter material comprises a filter paper layer. Support nets are arranged on the upper surface and the lower surface of the filter paper layer. The glass fiber composite filter material for the methanol filters has the advantage that the glass fiber composite filter material is high in integral stiffness, low in flow resistance, large in dust holding capacity, good in bursting strength and favorable for guaranteeing methanol filter effects.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a glass fiber composite filter material for methanol filters. Background technique [0002] The increasingly severe environmental protection situation, the potential risk of energy crisis and the needs of the national energy security strategy make the development of alternative fuels for burning methanol very urgent. Methanol is an organic fuel with physical and chemical properties similar to gasoline, which can be produced from natural gas, coal, and biological raw materials. Methanol has high thermal efficiency and less pollutants released by combustion, which can meet the power and emission requirements of current engines. At the same time, methanol in a liquid state at room temperature is convenient for transportation and distribution, and is suitable for popularization and application. Therefore, methanol is very suitable as an alternative energy source for fuel. [0003]...

AI Technical Summary

Problems solved by technology

However, the existing methanol filter has the following disadvantages: ① filter paper is generally plant fiber filter paper, and methanol has certain solubility to plant fiber, so it is difficult to guarantee the life and filtration quality of the methanol filter; ② the existing filter paper The filter material has a small dust holding capacity, insufficient stiffness and burst resistance, which is not conducive to the filtration of methanol; ③The existing methanol filter element, the filter paper is directly bonded to the end cap by resin adhesive, methanol has no effect on Resin has a certain solubility, which can easily cause the resin adhesive to fail, and then lead to separation between the filter paper and the end cap. Unfiltered methanol directly enters the inside of the filter element through the separation point, which is not conducive to the service life of the engine; ④The end of the existing filter element The cover is generally a galvanized metal end cover. Methanol will chemically react with zinc, copper, etc. under special conditions, which will affect the overall strength and filtering effect of the filter element.
