Embodiment 1

[0039] figure 1 Shown is a schematic diagram of the internal unit structure of an air purification device that can sustainably degrade indoor VOCs, including dehumidification unit, inlet draft unit, 1# purification and degradation room, 2# purification and degradation room, outlet VOCs monitoring and control unit, exhaust gas unit;

[0040] Wherein, the dehumidification unit is connected with the inlet air induction unit, the inlet air induction unit is respectively connected with the 1# purification and degradation chamber, the 2# purification and degradation chamber, the The outlet of the 1# purification and degradation chamber and the outlet of the 2# purification and degradation chamber are both connected to the outlet VOCs monitoring and control unit, and the outlet VOCs monitoring and control unit is connected to the exhaust unit;

[0041] The outlet VOCs monitoring and control unit includes a control panel ( figure 1 (not shown in the figure), used to control the coor...

Embodiment 2

[0043] figure 2 Shown is the schematic diagram of the connection relationship of the air purification device for sustainable degradation of indoor VOCs, including dehumidification unit, inlet air induction unit, 1# purification and degradation room, 2# purification and degradation room, VOCs monitoring and control unit, and exhaust unit. The 1# purification and degradation chamber is exactly the same as the 2# purification and degradation chamber.

[0044] Wherein, the dehumidifying unit includes a moisture absorbing material (1), a runner (2), a drying heater (3) and a steam pipe (4); the hygroscopic 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 procedure, the water-absorbing material on the runner (2) absorbs VOCs in the air The obtained dehumidified VOCs air is pumped to the 1# purification and degradation chamber or 2# purifica...

Embodiment 3

[0063] The air purification device for the sustainable degradation of indoor VOCs of the present invention integrates the adsorption and degradation of VOCs gas and the desorption and regeneration of activated carbon, is easy to be integrated 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 an indoor power socket to continuously purify the indoor air 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 and degradation chamber can also be opened at the same time, which can further improve the purification efficiency of VOCs gas. When the indoor air purification in one room reaches the standard, turn off the air purifier, unplug t...

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 a 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 houses, interior decoration has become inevitable, but newly decorated rooms often release a large amount of volatile organic compounds (VOCs) because of the decoration materials, causing serious indoor air pollution. According to statistics, the content of VOCs in most of the newly renovated houses exceeds the standard. Its source is not only the materials for house decoration, but also the liquefied gas and gas combustion in the kitchen, indoor smoking, etc., will produce VOCs, especially pollutants such as formaldehyde. In recent years, indoor air pollution has become more and more the focus of p...
