Description
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of the oil bath air filter was about 95-96%, and had the disadvantages of inconvenient use and high cost, so it has been replaced by a dry air filter having the advantages of light weight, low cost, convenient use and high filtering efficiency.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.

Working process and principle of filter
The whole filter housing 101 is divided into four cavities by a first partition plate 111, a second partition plate 112 and a bottom single partition plate 113, which are respectively an inlet filter cavity 103, a liquid filter cavity 104, an electrostatic dust collection cavity 105 and an outlet filter cavity 106, wherein the inlet filter cavity 103 is a coarse filter part, the liquid filter cavity 104 is a fine filter part, the electrostatic dust collection cavity 105 is a ultra-fine filter part, and the outlet filter cavity 106 is a safety protection part.
The inlet filter chamber 103 is divided into two parts by the partition plate 107, one part is connected with the inlet, the other part is connected with the liquid filter chamber 104, the engine operates to suck air, the air with impurities enters the primary filtering dust collection box 2 through the air inlet 108, the air with impurities goes downwards at high speed, the impurity air can be folded by 90 degrees when the primary filtering dust collection box 2 enters the secondary filtering dust collection box 3, because the inertial impurities are heavier than the air, the air enters the two chambers, and the heavier impurities enter the primary box body 201 because of the inertia of the heavy impurities.
The air secondary filtering dust collecting box 3 with a small amount of impurities goes upward, and large impurities are filtered down to fall into the primary box body 201 when passing through the filter screen 202. The inlet filter chamber 103 completes the coarse filtration and the air with fine dust enters the liquid filter chamber 104.
The dust-laden air entering the liquid filter chamber 104 enters the air-liquid mixer. The liquid sprayed by the liquid sprayer is collided, stirred and mixed in the gas-liquid mixer, so that the dust particles in the air are stuck by the liquid, and the air and the liquid with impurities enter the gas-liquid separator below the air-liquid mixer because the gas and the liquid are not fused.
The gas-liquid separator is provided with liquid collecting plates 413 which are mutually staggered, and liquid collides into the liquid collecting plates 413 under the action of gravity and suction force, enters liquid channels at two sides and flows into the liquid collecting cavity 601 to take away impurities. Air enters the electrostatic precipitator chamber 105 through an air passage 414 in the middle of the liquid collection plate 413.
The electrostatic dust collector belongs to the parts of electric dust collection, oxygen-enriched electricity-releasing dust collection and oxygen-enriched release.
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.
