Problems solved by technology

[0003] The working principle of the air filter is to block and absorb harmful particles in the air through the filter paper. The traditional air filter filter paper is relatively simple, and ordinary filter paper or nylon cloth is used. When this filter paper is used normally, although it can Adsorbs dust particles in the air, but it is difficult to remove the peculiar smell in the air, so the scope of use is relatively single

Embodiment 1

[0027] A method for increasing odor absorption by air filter paper, the steps are as follows:

[0028] 1) Install the purchased rolled filter paper on the conveying frame, and then convey it forward through the conveying roller, and install a pressure roller with rough surface wall at the rear end of the conveying roller; it is used to roughen the surface of the filter paper, which is convenient for follow-up water absorption;

[0029] 2) Prepare the deodorant solution in advance, then put the filter paper treated in the above step 1 into it, raise the temperature to 38°C, soak for 40 minutes, then take out the deodorant solution on the filter paper;

[0030] The deodorant liquid is made from the following raw materials: 6 parts of tea tree oil, 6 parts of eucalyptus oil, 15 parts of propylene glycol, 6 parts of surfactant, 6 parts of alcohol, 3 parts of citric acid, and 60 parts of deionized water;

[0031] When preparing, directly add all the raw materials into the stirring...

[0043] A method for increasing odor absorption by air filter paper, the steps are as follows:

[0044] 1) Install the purchased rolled filter paper on the conveying frame, and then convey it forward through the conveying roller, and install a pressure roller with rough surface wall at the rear end of the conveying roller; it is used to roughen the surface of the filter paper, which is convenient for follow-up water absorption;

[0045] 2) Prepare the deodorant solution in advance, then put the filter paper treated in the above step 1 into it, raise the temperature to 42°C, soak for 45 minutes, then take out the deodorant solution on the filter paper;

[0046] The deodorant liquid is made of the following raw materials: 8 parts of tea tree oil, 8 parts of eucalyptus oil, 25 parts of propylene glycol, 8 parts of surfactant, 8 parts of alcohol, 5 parts of citric acid, and 80 parts of deionized water;

[0047] When preparing, directly add all the raw materials into the stirring t...

Abstract

The invention provides a method for improving abnormal smell absorption by filter paper of an air filter and relates to the technical field of filter processing. The surface wall of the filter paper is made rough, and after soaking through deodorant liquid and drying processing, smell removing powder is added, and high temperature setting is performed, so that the abnormal smell absorption is improved. The method has the advantages that the process is simple; by soaking existing filter paper through the deodorant liquid and adding the smell removing powder, it is guaranteed that abnormal smell in the air undergoes absorption treatment when the filter paper is used, and it is guaranteed that the filtered air not only has no dust, but also has no smell.

Description

technical field [0001] The invention relates to the technical field of filter processing, in particular to a method for increasing odor absorption by air filter paper. Background technique [0002] An air filter is a device that removes particulate impurities in the air. When the piston machine (internal combustion engine, reciprocating compressor, etc.) is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so it must be equipped with an air filter. The air filter consists of two parts: a filter element and a housing. Therefore, the main requirements of the air filter are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance. [0003] The working principle of the air filter is to block and absorb harmful particles in the air through the filter paper. The traditional air filter filter paper is relatively simple, and ordinary filter paper or nylon cloth is used. When this f...
