Problems solved by technology

But due to TiO 2 The photocatalytic effect of the photocatalyst can only work under the irradiation of ultraviolet light, so the materials made in this way are not practical at present, and the cost is high
In addition, the safety assessment of nanoparticles on human health is still in the stage of experimental research, and the existing research results have initially confirmed that nanoparticles (especially metal oxides) are far more harmful to human health than aerosol particles in the conventional sense ( PM 10 and PM 2.5 )

Embodiment Construction

[0016] exist figure 1 , the shown material is made of activated carbon as the adsorbent with MnO 2 The board made after hybrid stamping has ventilation holes accounting for 60% of the total area.

[0017] In the embodiment shown in Figure 2, the air cleaner is constructed of four layers of different materials. After the polluted air is inhaled, it is firstly filtered by the primary filter (4) to absorb pollutants such as pollen and spores; then it is filtered by the second layer of adsorption material, the medium-effect filter (3), and the adsorption particle size is larger than PM 10 particles; then pass through the third layer, the HEPA high-efficiency filter (2), the adsorption particle size is smaller than PM 10 particles, bacteria and other pollutants; finally, the new type of purification filter material (1) absorbs and removes volatile organic compounds, thereby achieving the purpose of thoroughly purifying the air.

Abstract

The present invention belongs to the field of air purification and water purification technology. Its technical scheme is characterized by that it utilizes various adsorption materials (such as various active carbons, molecular sieves, zeolites, silica gels and active carbon fibre, etc.) with high specific surface area and high-valent oxides of Mn (such as various MnO2 and Mn2O3, etc.), and makes them undergo the processes of mixing and stamping to obtain various filter materials (including plates type, cabinet type, column type and granules type, etc.). The polluted air (or sewage) can be passed through said filter material, the pollutant can be adsorbed on the material surface by adsorbing agent, after the pollutant is oxidated by oxide of Mn, it can be converted into CO2 and H2O, and the adsorbing agent can be regenerated, so that said invention can high-effectively purify air or sewage.

Description

technical field [0001] The invention relates to an air purification (or water purification) device, in particular to a purification filter material capable of removing volatile organic compounds in the air or organic pollutants in water. Background technique [0002] At present, the well-known purification filter materials in China mainly use adsorption and electrostatic methods to remove pollutants. These materials include nylon mesh, non-woven fabrics, activated carbon, glass fiber filter paper, etc., all of which have a certain degree of adsorption capacity and better performance. The adsorption of pollutants in the air (such as dust, bacteria, volatile organic compounds, etc.), as well as trace pollutants in water (such as organic substances, heavy metals, etc.). However, the adsorption capacity of the adsorption material is limited, and after the adsorption reaches saturation, the phenomenon of pollutant penetration will occur. At this time, the adsorption material not...
