Problems solved by technology

[0002] At present, the formaldehyde removal products on the market are relatively single, and most of them use activated carbon or formaldehyde treasure for physical adsorption and decomposition
But they are not used for a long time, and the adsorption of formaldehyde on activated carbon will cause secondary pollution, which is not environmentally friendly.
The general filter uses a flat filter, the filtering area is relatively limited, and the effect is not very good

Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] Such as figure 1 and 2 Shown is a preferred embodiment of the present invention, the high-efficiency filter includes an outer frame 1 and a filter screen 2 fixed on the outer frame 1 . The outer frame 1 is an assembleable support, which plays a role in installing and fixing the filter screen 2. The filter screen 2 forms a non-planar network structure, and the network structure has a number of successively connected filter bodies 3 with air inlets 31. In this embodiment, the longitudinal cross-section of the filter body 3 is trapezoidal, and the edges of its large ends are sequentially fixe...

Abstract

The invention relates to a high-efficiency filter. The high-efficiency filter comprises an outer frame and a filter screen fixedly arranged on the outer frame, wherein the filter screen is filled with composite oxide particles and forms a non-planar net structure; the net structure is provided with a plurality of filtering bodies successively connected and equipped with air inlets; and a photocatalyst filter screen is arranged in each of the air inlets. According to the invention, the non-planar net structure is employed for filtering of harmful gas and increases a filtering area and air output, so the filtering efficiency and filtering and purifying effect of the filter are substantially improved.

Description

technical field [0001] The invention belongs to the technical field of filters, in particular to a high-efficiency filter for filtering formaldehyde. Background technique [0002] At present, the formaldehyde removal products on the market are relatively simple, and most of them use activated carbon or formaldehyde to carry out physical adsorption and decomposition. However, the use time is not long, and the adsorption of formaldehyde on activated carbon will cause secondary pollution, which is not environmentally friendly. Generally, the filter adopts a flat filter mesh, and the filtering area is relatively limited, and the effect is not very good. Therefore, it is necessary to further improve the existing filters. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-efficiency filter for filtering harmful gases such as formaldehyde. [0004] The present invention is realized in such a way that a high-effic...
