Embodiment Construction
[0010] A method for thoroughly washing an air filter element with high-pressure clean water, the method steps are as follows:
[0011] 1. Configure the soaking solution: the components and mass percentages of the soaking solution are: 0.2% detergent, 0.2% medical alcohol with a concentration of 75%, 0.1% ethylene glycol, and the rest is water; after the soaking solution is configured, Stir well and leave for half an hour until the foam decreases;
[0012] 2. Soaking: Soak the frame structure fiber non-woven fabric air filter element completely in the soaking liquid for 3 hours; if soaking the activated carbon structure air conditioning filter element, the soaking time is 30 minutes, soak it still, turn it up and down several times when taking it out;
[0013] 3. Water-permeable cleaning: Take out the filter element from the soaking liquid, put the filter element close to the wall at an angle of 45 degrees, and use the high-pressure water gun to clean the frame structure fiber ...

The invention relates to an air filter element for a vehicle engine and an air conditioner, particularly a method for thoroughly washing air filter element by high pressure clear water. The method comprises the following steps: I, preparing a soaking liquid: the soaking liquid comprises the components in percentage by weight: 0.2% of a detergent, 0.2% of 75% medicinal alcohol, 0.1% of ethylene glycol and the balance of water; and after the soaking liquid is prepared, uniformly stirring the soaking liquid and putting the soaking liquid for half an hour till foam is reduced. The method provided by the invention can be used for safely and effectively cleaning a fiber non-woven fabric air filter element in a frame structure and an air conditioner filter element in an activated carbon structure, the using effect of the filter element is not affected, the organization structure of the filter element material is not damaged, the service cycle of the filter element is prolonged, the cost is lowered, and the abrasion of the engine is effectively reduced.
Description
Technical field: [0001] The invention relates to an air filter element for vehicle engines and air conditioners, in particular to a method for thoroughly washing the air filter element with high-pressure water. Background technique: [0002] As the "nose" of the vehicle engine and air conditioner, the air conditioner filter element filters the dust and debris in the air and prevents the dust particles from wearing the engine piston and other parts. The existing air conditioner filter elements mostly use frame structure fiber non-woven air filter elements At present, there is no safe and effective cleaning method for these two types of filter elements, so once the two types of filter elements reach the number of kilometers used by the vehicle, they can no longer be used. However, the filter element itself is not dirty except for being dirty If it is damaged, discard it directly, which is a waste of cost, and at the same time reduces the life cycle of the filter element.
