Problems solved by technology

[0005] The present invention overcomes the deficiencies in existing air purifiers that the adsorption material is easily affected by the water content of the purified gas, the adsorption material is easily saturated by adsorption, the online desorption regeneration process is complicated, the desorption is easy to generate secondary polluting gas, and the air purification effect is poor. An air purification device suitable for air purifiers that can continuously degrade indoor VOCs is provided, so that indoor air VOCs can be continuously purified, activated carbon adsorption materials can be regenerated synchronously, and the adsorption pollution can be completely degraded, greatly extending the service life of the adsorption materials. Significantly improved the efficient air purification efficiency

Embodiment 1

[0038] figure 1 Shown is a schematic diagram of the internal unit structure of an air purification device that can sustainably degrade indoor VOCs, including a dehumidification unit, an inlet air induction unit, 1# purification and degradation chamber, 2# purification and degradation chamber, outlet VOCs monitoring and control unit, exhaust unit;

[0039] Wherein, the dehumidification unit is connected with the inlet air induction unit, and the inlet air induction unit is respectively connected with the 1# purification degradation chamber and the 2# purification degradation chamber, and the The outlet of the 1# purification degradation chamber and the outlet of the 2# purification degradation chamber are all connected to the outlet VOCs monitoring and control unit, and the outlet VOCs monitoring and control unit is connected to the exhaust unit;

[0040] The outlet VOCs monitoring and control unit includes a control panel ( figure 1 not shown in ), used to control the coordi...

Embodiment 2

[0042] figure 2 Shown is a schematic diagram of the connection relationship of the air purification device for sustainable degradation of indoor VOCs, including a dehumidification unit, an inlet air unit, 1# purification degradation chamber, 2# purification degradation chamber, VOCs monitoring and control unit, and exhaust unit. 1# purification degradation chamber is exactly the same as 2# purification degradation chamber.

[0043] Wherein, the dehumidification unit includes a moisture-absorbing material (1), a runner (2), a drying heater (3) and a steam pipe (4); the moisture-absorbing material (1) is loaded on the runner (2), The runner (2) is sealed and divided into two areas, each of which accounts for 50% of the area; when one of the areas is in the air dehumidification process, the water-absorbing material on the runner (2) absorbs VOCs in the air moisture, the VOCs air obtained after dehumidification is pumped into the 1# purification degradation chamber or the 2# pur...

Embodiment 3

[0061] The air purification device for sustainably degrading indoor VOCs of the present invention integrates VOCs gas adsorption degradation and activated carbon desorption regeneration, is easy to integrate into a shell, and has the characteristics of being portable and mobile. Therefore, the system is packaged as an integrated air purifier with an external junction power plug, which can be connected to the indoor power socket, and the indoor air can be continuously purified conveniently and quickly. The specific implementation steps of the continuous purification are the same as those in the embodiment 2. When implementing the indoor VOCs air purification process, the discharge plasma reactor corresponding to the purification degradation chamber can also be turned on at the same time, which can achieve the goal of further improving the purification efficiency of VOCs gas. When the indoor air purification in a room reaches the standard, turn off the air purifier, unplug the po...

Abstract

The invention discloses an air purification device and method capable of continuously degrading indoor VOCs. The air purification device comprises a dehumidification unit, an inlet air inducing unit, a first purification and degradation chamber, a second purification and degradation chamber, an outlet VOCs monitor and control unit and an exhaust unit. According to the air purification device capable of continuously degrading the indoor VOCs, VOCs gas adsorption degradation and activated carbon desorption regeneration are integrated, and integrated shell mounting is easy; the air purification device has the beneficial effect of being convenient to move, an adsorbing material does not need to be replaced frequently, the consumption cost of an activated carbon adsorbing material is greatly reduced, and the service life of the activated carbon adsorbing material is prolonged; and a dehumidification pretreatment method is adopted, the efficiency that activated carbon purifies and adsorbs the VOCs later is greatly improved, the air purification effect is greatly improved, and the good market potential is achieved.

Description

technical field [0001] The invention relates to the technical field of indoor air purification, in particular to an air purification device and method for sustainably degrading indoor VOCs. Background technique [0002] With the development of social economy, people have higher and higher requirements for their own living standards, especially living conditions. When building a house, interior decoration has become inevitable, but newly decorated rooms often release a large amount of volatile organic compounds (VOCs) due to the decoration materials, causing serious indoor air pollution. According to statistics, most of the VOCs content in newly renovated houses exceeds the standard. Its source is not only the materials for house decoration, but also liquefied petroleum gas and gas combustion in the kitchen, indoor smoking, etc. will produce VOCs, especially formaldehyde and other pollutants. In recent years, the problem of indoor air pollution has increasingly become the f...
