High-efficiency mesh channel hierarchical air filtering structure

Abstract

The invention relates to a high-efficiency mesh channel hierarchical air filtering structure which is composed of a first level filtering structure, a second level filtering structure, a third level filtering structure and a fourth level filtering structure in sequence in series. Each level filtering structure is formed by multipled regular triangular prism channel filtering units, wherein the regular triangular prism channel filtering units are formed by planar filtering materials I and zigzag folded filtering materials II in an alternate and overlying mode. Equilateral triangular partition plates are arranged at the same intervals in each regular triangular prism channel filtering unit. The partition plates in adjacent regular triangular prism channel filtering units are arranged in a staggered mode, so that the fact that airflow flows in a staggered mode to pass through regular triangular prism side filtering materials is guaranteed, the dwell time of the airflow in a structural unit is prolonged, an effective filtration area is increased, and trapping efficiency is improved. According to the high-efficiency mesh channel hierarchical air filtering structure, a hierarchical series design, along the direction of the airflow, is adopted, each level structure is made of different filtering materials, and therefore classified trapping of various particulate matters and gaseous pollutants in the airflow can be achieved.

Description

technical field [0001] The invention relates to a high-efficiency mesh channel graded air filter structure. Background technique [0002] The air filter element used in the vehicle air-conditioning system, according to the filter material, has gone through three stages: oil wet type, oil bath type and then paper filter element; according to the structure, it has experienced flat type, folded clapboard type, Folding without partition, folding cylinder and other stages. Due to the low filtration efficiency, the metal mesh filter element has tended to be eliminated in the vehicle air filtration system. Since the 1950s, a new material paper filter element has appeared. After continuous improvement in technology, it has a high filtration efficiency of 95% to 99%, low cost, easy replacement, and small structural size, so it has been widely used. However, due to the serious pollution of particles of various sizes in the air environment of the road where the vehicle is driving, it...
