Description

Air filter

Technical Field

The utility model belongs to the technical field of filtration, concretely relates to air cleaner.

Background

The main task of automotive air cleaners is to filter out airborne particles in the air prior to entering the cylinder to reduce wear on the cylinder, piston, and piston rings. The early automobile air filter was mostly an oil bath air filter, which conducted air into the oil cup containing engine oil and adhered suspended particles in the air through the engine oil, however, under normal circumstances, the filtering efficiency of the oil bath air filter was about 95-96%, and had the disadvantages of inconvenient use and high cost, so it has been replaced by a dry air filter having the advantages of light weight, low cost, convenient use and high filtering efficiency. The dry air filter mainly utilizes the paper filter element to filter out suspended particles in the air, and the filtering efficiency can reach more than 99.5 percent, but the filter of the type has the following defects:

1. because the filter element is made of paper, the filter element will deteriorate after contacting with water vapor, so that the resistance of air flowing through the filter element is increased suddenly, and the original filtering efficiency can not be recovered even after the water vapor is removed by the filter element, thereby shortening the service life.

2. In the state that the filter cartridge is not deteriorated, the micro-suspension particles in the air can still enter the engine through the filter cartridge and cause abrasion of related parts, so that the filtering efficiency is still to be improved.

3. The paper filter has good air treatment amount at the initial use stage, but the air treatment amount is continuously reduced along with the continuous accumulation of dust to block the air passing holes of the filter paper, so that the air inflow is insufficient, the oxygen inlet amount of an engine is insufficient, the combustion is insufficient, the vehicle power is reduced, the oil consumption is saved, and the fuel cost is increased for a vehicle owner. Due to insufficient combustion, the standard exceeding is not beneficial to environmental protection.

4. The filter needs to be replaced frequently, the quantity of light, medium and heavy automobiles in China is about 3000 thousands, and the air inlet processing units of the automobiles are all made of paper filters, and about 2 hundred million of the air inlet processing units are replaced every year. Each vehicle averagely changes 2-20 air filters every year, one low-order number is 7, each high-quality paper filter is about 150 yuan, 1050 yuan is needed for changing the filter for one year for each vehicle, 300 million yuan is needed for the total price of the filters changed for vehicles in China, the wood consumption is huge, and the energy is not saved and the environment is protected;

5. as many car owners think that the price of the high-quality filter is slightly expensive or unknown, some inferior filters are purchased, the inferior filters cannot meet the filtering requirement, a large amount of impurities enter the engine, the service life of the engine is reduced, the engine is maintained in advance, and the car maintenance cost is greatly increased.

The air after fine filtration in the liquid filter cavity 104 enters the high-voltage electrostatic dust collection environment from the lower part of the electrostatic dust collection cavity 105 upwards. The electrostatic precipitator cavity 105 is used for adsorbing front part of the missing impurities and moisture on the dust collecting plate 501 through high voltage static electricity to achieve super-pure air. During the high-voltage electrostatic precipitation, a large amount of oxygen-rich air favorable for combustion of engine fuel is released together with super-pure air to enter the engine through the outlet filter chamber 106.

The outlet filter chamber 106 is a safety protection part, and plays a safety protection role when the front part fails to filter.
