Problems solved by technology

[0003] However, the existing air purifiers on the market have the following defects and deficiencies: (1) It can only achieve limited functions such as dust removal, PM2. For example, there are a lot of petroleum hydrocarbons and freon in factories, there are a lot of germs in hospitals, and there are a lot of organic and inorganic volatile toxic and harmful gases in laboratories; (2) the current air purifiers mostly use HEPA filters Or activated carbon filter for adsorption, there are problems such as small adsorption capacity and limited adsorption effect

Embodiment 1

[0031] Such as Figure 1(a) and 1(b) As shown, it is a novel filter device with a cylindrical structure in the present invention, which can enhance the purification effect of the air purifier. The filter device includes a filter screen support 1 , an adsorption layer 2 and a hollow round platform 3 . The adsorption material of the adsorption layer 2 is directly filled into the filter screen support 1, and the adsorption material of the adsorption layer 2 is granular adsorption material, specifically granular zeolite.

[0032] Further, the filter screen support 1 is made of stainless steel and has good support. The distance between the inner and outer layers of the net can be adjusted, and the inner layer net can also be eliminated. The mesh size of the filter screen support 1 is smaller than the particle size of the granular adsorption material.

[0033] Further, the hollow round table 3 and the filter screen support 1 are assembled through the slot in the lower part of the ho...

Embodiment 2

[0035] Such as Figure 2(a) and 2(b) As shown, it is a novel filter device with a multi-layer cylindrical mesh structure in the present invention, which can enhance the purification effect of the air purifier. Round filter holder 1.

[0036] Further, the multi-layer concentric circle filter screen support 1 and the filter screen container 4 are made of polyamide plastics, which have good support. The sponge-shaped material and the granular adsorption material are distributed at intervals, wherein the massive sponge material can be: a block sponge formed by mixing powdery porous aromatic framework material with a binder solution and then freeze-dried, and the granular absorbent material can be activated carbon. And the grid size of the concentric circular filter screen support 1 is smaller than the particle size of the granular adsorption material.

[0037] Further, the hollow round table 3 and the filter container 4 are connected through the slot at the bottom of the hollow...

Embodiment 3

[0040] Such as Figure 3(a) and 3(b) As shown, it is a novel filter device with a hollow hexagonal cylindrical structure in the present invention, which can enhance the purification effect of the air purifier. The filter device includes an internal support 5, an adsorption layer 2 and a split filter screen support 1. One end of the internal bracket 5 is connected with a hollow round table, which can fix the new filter device in the middle of the cylindrical filter element. The split filter screen bracket 1 is assembled through the slot, which is convenient for the disassembly and replacement of the purification membrane.

[0041] Furthermore, both the internal bracket 5 and the split screen bracket 1 are made of acetal resin, which has good support, and its thickness and grid size are adjustable.

[0042] Further, the adsorption layer 2 adopts an air filter membrane, and the air filter membrane is a non-woven fabric loaded with a powdered metal-organic framework material. Th...

Abstract

The invention belongs to the field of air cleaning equipment, and concretely relates to a filtering apparatus capable of enhancing purifying effect of an air purifier. The filtering apparatus comprises the filter layers arranged at the inner side and / or outside of the filtering apparatus of the air purifier, wherein the quantity of the filter layers is more than one, the shape of the above filter layer and the above filtering apparatus of the air purifier are matched, each filter layer comprises two layers of filter screen supports positioned at outside and an adsorption layer arranged between two layers of the filter screen supports, the adsorption layer employs an air filtering membrane, block sponge or a granular absorbent as the adsorption materials, and the adsorption materials in each filter layer are same or different. The filtering apparatus can effectively solve the problems of limited types of the harmful gas purified by the current air purifiers and small adsorption quantity, has the advantages of simples structure, convenient modification and low cost, and is suitable for air purifying on different occasions.

Description

technical field [0001] The invention belongs to the field of air purification equipment, and more specifically relates to a filter device for enhancing the purification effect of an air purifier. Background technique [0002] With the improvement of the level of industrialization, industrial pollution, automobile exhaust, smog, indoor formaldehyde, second-hand smoke, etc. have caused air pollution to become more and more serious, resulting in a large amount of toxic and harmful gases such as VOCs, nitrogen oxides, sulfur oxides, and carbon oxides in the indoor air. , a serious threat to people's physical and mental health. When the toxic and harmful gases in the living room exceed a certain concentration, people will feel headache, nausea, vomiting, fatigue, etc. in a short period of time. Nervous system, causing memory loss and other serious consequences. At the same time, with the improvement of economic level, people begin to pay attention to the air quality of their li...
