technical field

The utility model relates to the technical field of an air conditioner purifier. To be precise, it is a multi-stage filter air conditioner purifier. the

Background technique

Primary filter 1 is a combined air filter layer composed of metal filter screen and glass fiber paper. The TiO ₂ purification section is a support made of water-resistant kraft paper. Activated carbon is bonded to the support to form an adsorption layer. Nano-TiO ₂ is coated on the surface of the activated carbon. The activated carbon and TiO ₂ photocatalyst form a multi-layer honeycomb structure with through holes. Integral activated carbon- _TiO2 composite purification net 10, with an ultraviolet lamp 11 between the two activated carbon- _TiO2 composite purification nets 10.

1) The combined air outlet with metal filter screen and glass fiber paper as the air filter layer is used in the air outlet of the air conditioner, and the area of the filter air outlet is increased during design to reduce resistance and achieve the purpose of energy saving. Modular combined filter air outlet is adopted, which is easy to disassemble and replace the filter screen, ensuring long-term efficient and stable operation of the system. the

2) Using an improved catalyst doped with C element in TiO ₂ greatly improves the air purification efficiency. The support body made of water-resistant kraft paper, activated carbon and TiO ₂ photocatalyst are constructed into a honeycomb-shaped integral purification net with a multi-layer structure with straight holes (see Figure 2). The supporting body forms hexagonal honeycomb holes, and the side length of the hexagon is 1 mm. The hexagonal honeycomb acts as a through-hole for light and air. Activated carbon is bonded on the support to form an adsorption layer. Polybutylacrylate emulsion is used as the adhesive, and the activated carbon used is 60-400 mesh high iodine value powder carbon such as coconut shell carbon, fruit shell carbon, etc., and a uniform activated carbon layer with a thickness of about 1 cm should be formed during loading. Disperse the nano- _TiO2 powder in water by ultrasonic dispersion method to prepare a slurry with a solid content W=0.05 of agglomerates larger than 100nm, and then dip-coat the composite carrier formed by the support body and activated carbon with the above-mentioned _TiO2 slurry for 3 times , Baked at 160°C and vacuum for 4h after each dip coating. Thus, a thin shell structure in which nano- _TiO2 is coated on the surface of activated carbon is finally formed.

3) Nano-TiO ₂ is loaded on the inner wall of the air-conditioning purification section, and tetra-n-butyl titanate is used as a raw material to prepare an aluminum sheet-loaded nano-TiO ₂ film that can be photocatalytically degraded by sol-gel method. Pollutants in the filter section improve purification efficiency. After the nano- _TiO2 film is loaded on the inner wall, the dust is not easy to deposit, and at the same time, the bacteria attached to the inner wall are killed to prevent secondary pollution.

4) In the air purification section, each functional section adopts modular integration, which is convenient for disassembly and cleaning. The module sections are: metal filter screen, glass fiber paper as the combined tuyere section of the air filter layer, electrostatic dust removal section, and photocatalytic degradation section. the
