Problems solved by technology
Due to the high wind speed in the central area of the ventilation pipe, this will cause a large penetration rate in the central area of the air filter, which becomes the "short board" of the filter and directly affects the filtration efficiency of the air filter

Embodiment 1
[0062] Example 1, select a ventilation duct with a diameter of 100×100mm, given a wind speed or air volume of 0.80.8m / s, use the SIMPLE algorithm to calculate and simulate the velocity field on the air duct section, the velocity field on the air duct section is as follows figure 1 As mentioned above, the ventilation duct opening can be divided into 3 filter areas through the illustration. At this time, the difference between the sum of the product of the filtration speed determined by each filter area and the area of each area and the set air volume should be less than 5%. Each filter area is composed of folded filter material 5 and partition 6, and the filter area 1 at the center is in the shape of a square, and the rest of the filter areas (2, 3) in turn surround the filter area 1 at the center to form a back. type area. Each filter area is glued and sealed with each other to form a whole. The area of the filter area in the center is selected with a single layer weight ...

Abstract
The invention discloses a clapboard air conditioner filter, which comprises a ventilating filter port, a frame, folding filter materials and clapboards. The clapboards are arranged in folding cavities of the folding filter materials; the ventilating filter port is at least divided into three filter zones; each filter zone consists of a folding filter material and a clapboard; the filter zone position on the central part is square, and the rest filter zones enclose the filter zone on the central part in turn to form a hollow square area; the filter zones are glued and sealed with one another through glue; and the filter efficiencies of the filter materials selected by the filter zones are decreased gradually in turn from the square filter zone on the central part to the hollow square filter zones enclosing the filter zone on the central part. Besides, the invention discloses a method for dividing filter zones at a ventilating filter port of a bag air conditioner filter. Two technical indexes, namely the filter efficiency and the clogging capacity, and the economical index of running cost are considered, and the characteristic of fluid speed field in a ventilating duct is combined so as to improve the filter efficiency of the air filter.
Description
technical field [0001] The invention relates to an air filter, more particularly to a clapboard type air conditioner air filter designed considering the inhomogeneity of the fluid velocity field in a rectangular ventilation pipe. Background technique [0002] The main task of indoor air purification is to remove indoor dust particles, and the most effective way is to use an air filter to filter and purify the air. Filtration is a kind of separation technology, which mainly relies on the filter material to capture and intercept the solid particles suspended in the fluid, so as to separate the solid particles from the air. [0003] Rectangular ventilation ducts are more common in ventilation systems and are an important part of ventilation systems. Using the knowledge of fluid mechanics, the velocity field of the fluid in the rectangular ventilation pipe can be derived. It is found that the velocity in the ventilation pipe presents a quadratic curve distribution, that is, the...
