Description

Technical Field

[0001] The invention belongs to the technical field of air purification, and in particular relates to an indoor formaldehyde treatment device. Background Art

[0002] As people's living standards improve, indoor air quality is receiving increasing attention. Formaldehyde is a common indoor pollutant, primarily derived from decoration materials, furniture, adhesives, and other sources. Long-term exposure to formaldehyde can lead to respiratory diseases, allergic reactions, and even cancer. Therefore, the treatment of indoor formaldehyde has always been a key issue in the environmental protection field. Currently, common formaldehyde treatment methods on the market include ventilation, activated carbon adsorption, photocatalytic degradation, and air purifiers. However, these methods have the following problems:

[0003] 1. Although activated carbon has good adsorption properties, its adsorption capacity is limited and needs to be replaced regularly. If the activated carbon is not replaced in time after it is saturated with adsorption, the formaldehyde adsorbed on the activated carbon may be released back into the air, causing secondary pollution.

[0004] Second, the formaldehyde concentration, humidity, temperature and other conditions in different rooms vary greatly, and most existing formaldehyde treatment equipment is difficult to flexibly adapt to these changes; for example, some equipment is not effective in high humidity environments, while others consume too much energy in low formaldehyde concentration environments;

[0005] In view of the deficiencies in the prior art, the present invention provides an indoor formaldehyde treatment device, aiming to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an indoor formaldehyde treatment device that can avoid the problem of secondary pollution caused by untimely replacement of activated carbon after saturation.

[0007] To achieve the above object, the present invention is implemented by adopting the following technical solutions:

[0008] An indoor formaldehyde treatment device comprises a shell;

[0009] The shell is provided with a first sliding hole and a second sliding hole near its bottom; a plurality of sliding grooves are provided on the two inner side walls of the shell; a first drawer for storing working activated carbon is slidably connected to the first sliding hole; a second drawer for storing spare activated carbon is slidably connected to the second sliding hole; a plurality of protrusions adapted to the sliding grooves are provided on both sides of the first drawer and the second drawer;

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention is designed with double-layer drawers, in which working activated carbon and spare activated carbon are placed respectively. When the working activated carbon is saturated with adsorption, it can automatically switch to spare activated carbon, and the saturated activated carbon is thermally regenerated by the electric heating core to avoid secondary pollution, extend the service life of the activated carbon, and reduce the replacement frequency.

[0023] 2. The present invention introduces a porous ceramic plate. The TiO2 catalyst coated on the porous ceramic plate can effectively decompose formaldehyde. The porous structure increases the specific surface area of ​​the catalyst and improves the efficiency of the photocatalytic reaction.
