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.

The specific embodiment
Comply with below in conjunction with accompanying drawing 1-4 and inventor the instantiation that technical scheme of the present invention is completed, the present invention is described in further detail.
Shown in Figure 1, overall structure of the present invention is comprised of the level Four filtration, is followed successively by first order filtration 1, second level filtration 2, third level filtration 3 and fourth stage filtration 4 along the air current flow direction.Wherein: first order filtration 1 adopts that the coarse granule filtrate separates, second level filtration 2 adopt in granule filter material separate, third level filtration 3 adopts the fine grained filtrates to separate with fourth stage filtration 4 to adopt the gaseous contaminant absorbent filter mediums to separate.Instantiation is selected first order filtration 1, and the present invention will be described, and the situation of other grades filtration is identical therewith.Instantiation selects square external boundary to be illustrated, and other external boundary planforms (round, oval etc.) are applicable filter structure of the present invention also.
shown in Figure 3, air filtration structure of the present invention, every grade of body making method such as Fig. 2, by plane filtrate I and in a zigzag folding filtrate II alternately stack form regular triangular prism passage filter element in parallel and form, utilize the Fluid Mechanics Computation technology, under filtration velocity (1-5m/s) condition of determining to occur in common vehicles air-conditioning, the length of side of regular triangular prism passage filter element is 1-3 centimetre, regular triangular prism passage filter element is separated by equilateral triangle dividing plate 9, in same regular triangular prism passage filter element, the adjacent separator spacing is 5-10 centimetre, adjacent regular triangular prism unit internal partition location dislocation is arranged.
pending contaminated air enters the first triangular prism passage 5 by air admission hole in Fig. 3 or Fig. 4, because the first triangular prism passage 5 ends are equilateral triangle dividing plate 9, the air-flow that is admitted to continually the first triangular prism passage 5 is stopped by equilateral triangle dividing plate 9, can not flow forward along the duct, air-flow can pass through three side filter material layers of the first triangular prism passage 5 under ever-increasing pressure-acting, the particulate pollutant that particle diameter is larger can be trapped within three side filter material layers of the first triangular prism passage 5, after filtering, air enters respectively the second triangular prism passage 6, the 3rd triangular prism passage 7, the 4th triangular prism passage 8, realized so air-polluting filtration for the first time.Simultaneously, the contaminated air in other air intake passages adjacent with air intake passage 5 also can enter respectively the second triangular prism passage 6, the 3rd triangular prism passage 7, the 4th triangular prism passage 8 after filtering for the first time.Take the second triangular prism passage 6 as example, air after filter for the first time in the adjacent duct that in the second triangular prism passage 6, air-flow collects from three sides, after the filter that such the second triangular prism passage 6 sides are collected, air can enter in the 5th triangular prism path 10, as shown in Figure 4 along the second triangular prism passage 6.In like manner, enter respectively the 6th triangular prism passage 11 and the 7th triangular prism passage 12 through the air after filtering for the first time by the 3rd triangular prism passage 7 and the 4th triangular prism passage 8.The air that comes together in the 5th triangular prism path 10, the 6th triangular prism passage 11 and the 7th triangular prism passage 12 also can with the direction diffusion of the first triangular prism passage 5 Air flow patterns to triangular prism three sides, form branch's air-flow; Take whole filter as references object, air draught is crisscross in passage, flows in the cross-flow mode.Especially, take the 5th triangular prism path 10, the 6th triangular prism passage 11 and the 7th triangular prism passage 12 as example, part air-flow in these passages is because the solid block of end stops, will inevitably see through the 6th triangular prism passage 11 and come together in the 8th triangular prism passage 13, air in the 8th triangular prism passage 13 can directly enter with the pattern of the second triangular prism passage 6 next passage that is attached thereto again, then flows with the mode filtering of the first triangular prism passage 5.
In addition, the filtration channel quantity of every grade of filtration parallel connection can be determined according to the actual air quality requirements, after incoming flow process first order filtration 1, with the type of flow identical with first order filtration 1 through second and third, the level Four filtration, thereby realize the efficient purpose of removing various air pollutants.
