Problems solved by technology

[0004] In fact, CO in the air 2 , formaldehyde, volatile organic compounds (VOC) and other harmful gases have low concentrations and many types, which will lead to competitive adsorption among various gases, making it difficult for current devices to completely remove CO in the air 2 , formaldehyde, volatile organic compounds (VOC) and other harmful gases, and will cause secondary pollution

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0024] Traditional activated carbon adsorbents, formaldehyde-specific adsorbents, air-conditioning formaldehyde removal modules, etc. remove water vapor and CO 2 Simultaneous adsorption, so it will compete with formaldehyde for adsorption, resulting in poor formaldehyde removal effect. Moreover, the adsorbed formaldehyde gas cannot be completely degraded and removed, causing secondary pollution in the desorption process. In view of the above problems, the present invention proposes a rotatable, uninterrupted adsorption-degradation indoor air purification device with a built-in purification function, which absorbs water vapor and CO in the air layer by layer. 2 , so as to avoid the impurity gas from reducing the adsorption performance of the material to formaldehyde, and co...

Abstract

The invention provides a rotatable and uninterrupted adsorption-degradation integrated indoor air purification device, which includes a multi-stage adsorption system and a desorption system. Water vapor layer, carbon dioxide removal layer and formaldehyde removal layer; water vapor removal layer, carbon dioxide removal layer and formaldehyde removal layer are installed on different rotatable chassis; the gas detection module is installed at the air outlet, and the extracted air flows from the air inlet to the air outlet , and the formaldehyde concentration at the air outlet is detected by the gas detection module; when the formaldehyde removal layer reaches the set adsorption saturation concentration, it enters the desorption system and is degraded by the ultraviolet lamp. After the water vapor removal layer and the carbon dioxide removal layer reach the set time It enters the desorption system and is heated by a heater for desorption. The invention can efficiently remove harmful gases such as formaldehyde and VOC, and realize the recycling and reuse of materials.

Description

technical field [0001] The invention relates to an indoor air purification device, which is suitable for cleaning dust, PM2.5 particles, CO 2 , formaldehyde, volatile organic compounds (VOC) and other harmful gas concentrations require a certain amount of indoor space and other places that need efficient purification. Background technique [0002] With the improvement of people's production and living standards, the reports of disease incidents caused by formaldehyde and other major polluting gases in house decoration are gradually increasing, and the indoor environmental pollution problem has been paid more and more attention by people. Especially when the concentration of harmful gases such as formaldehyde and volatile organic compounds (VOC) exceeds a certain concentration, it will cause more serious symptoms such as nausea and vomiting, coughing and chest tightness, and long-term exposure to harmful gases such as formaldehyde and volatile organic compounds (VOC) may lead...
