Problems solved by technology

This kind of filter cannot be disassembled because the shell and the end cover are pressed together, so it is usually scrapped after being used until the maintenance cycle is replaced.
[0004] In the prior art, the recycling of waste air filters is generally aimed at dismantling and recycling the casing and end caps, and there is no method for recycling the filter paper of the engine air filter

Abstract

The invention provides repair liquid for gap repair of filter paper of a waste air filter and relates to the technical field of filter paper recycling. The repair liquid is prepared from, by weight, 12% of flax fiber, 1.5% of aluminum hydroxide, 3.5% of talcum powder, 0.2% of yttria, 15% of silica gel, 20% of ethyl alcohol and the balance water. The recycled filter paper is subjected to many times of purging by means of high-pressure nitrogen flow, filtrate on the surface and in gaps of the filter paper is removed, then the gaps of the filter paper are repaired by means of the repair liquid, and accordingly the original air filtering effect is restored. The gaps of the filter paper can be filled with the repair liquid used in the gap repair process, and the large gaps can become smaller; meanwhile, the repair liquid wraps the surfaces of fibers forming the filter paper, and elasticity and the air filtering effect of the filter paper are improved.

Description

Technical field [0001] The invention relates to the technical field of filter paper recycling and reuse, and in particular to a repair liquid for repairing voids in waste air filter filter paper. Background technique [0002] The air filter is an important part of the engine. Its function is to filter out particles such as dust and mechanical impurities in the air entering the engine to reduce engine wear, optimize the engine's combustion process, and reduce the emission of organic pollutants such as carbon monoxide. [0003] At present, the air cleaner used in automobiles at home and abroad is usually the shell and the end cover are stamped and sealed into one body through a stamping process, and a filter element with a paper filter element is connected to the end cover of the closed cavity of the shell. This kind of filter cannot be disassembled because the shell and the end cover are pressed into one body, so it is usually scrapped after being used to the maintenance period and ...
