Engine air filter element with hollow fiber film

Abstract

The invention discloses an engine air filter element with a hollow fiber film as a filtering material, and particularly relates to an engine air filter element with a polytetrafluoroethylene hollow fiber film as a filtering material. The engine air filter element with the hollow fiber film has the characteristics of being dustproof, oil-proof, anti-dust, resistant to corrosion, high temperature and low temperature, extremely high in dust holding capacity, capable of being cleaned and recyclable, is connected with an engine intake channel through quick connectors such as hasps or buckles, and has a single-end sealing mode and a dual-end sealing mode. The engine air filter element with the hollow fiber film is particularly suitable for engine air filters in severe environments.

Description

technical field [0001] A device for filtering input air of an internal combustion engine, especially an engine air filter element using a hollow fiber membrane as a filter material, especially an engine air filter element using a polytetrafluoroethylene hollow fiber membrane as a filter material . Background technique [0002] All internal combustion engines need to draw air from the atmosphere, and the input air must be filtered, otherwise, the dust in the atmosphere will cause the cylinder to wear out quickly and fail. There are two types of traditional air filters, dry type and wet type, as well as a mixture of these two methods. Among them, the mainstream dry air filter mainly adopts the filter screen made of fiber, which is made into sheet, paper, and cloth, and is folded to expand the area to form various styles of air filter elements. Some wet air filters use oil film adhesion, some use water washing method, and cooperate with rotating air flow to realize dust treat...

Problems solved by technology

[0003] Although these technologies have been developed for hundreds of years, there are still many problems to be improved: 1. The air filter element needs to be replaced frequently, especially for tanks, armored vehicles, and engineering vehicles working in harsh environments. High concentrations of dust will cause The air filter fails quickly, and the maintenance effort and cost are extremely high

2. The traditional air filter element + wet dust removal system is too large in size and complex in structure, which is not conducive to the optimization of vehicle structure

3. The traditional air filter system has a large wind resistance, resulting in a decrease in engine efficiency. According to data, the power of a certain type of tank for air filtration accounts for 5% of the total power

4. Most of the traditional air filter elements are disposable products, which consume a lot of resources. There are 500 million cars in the world, which consume tens of billions of filter elements annually and generate 1 million tons of garbage
