Embodiment Construction

[0031] Other embodiments, features and advantages of the present invention, as well as the structure and operation of various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The various embodiments of the invention presented herein are by way of illustration and not limitation.

[0032] In one embodiment (see figure 1 ), the air cleaning device of the present invention includes a housing 1. An adsorption filter 2 and an active oxide generator 3 are installed in the housing 1 . The adsorption filter 2 is installed on the surface of the housing 1 and exposed to the air. In this way, the adsorption filter 2 has a larger surface area to absorb air pollutants in the surrounding environment by diffusion. The active oxide generator 3 is surrounded by the housing 1 and the adsorption filter 2 and is used to generate active oxides. There is no barrier between the adsorption filter 2 and the active oxide generator 3...

Abstract

An air cleaning apparatus and a method for removing air contaminants are disclosed. The air cleaning apparatus comprises a housing (1) in which at least one adsorbent filter (2) and at least one reactive oxidizing species (ROS) generator (3) are installed. The adsorbent filter (2) is positioned at the surface of the housing (1) and exposed to the air for adsorption of air contaminants. The ROS generator (3) for generation of ROS is enclosed by both the housing (1) and the adsorbent filter (2). The method comprises the following steps: a) the air cleaning apparatus is placed in the polluted environment; b) the adsorbent filter (2) adsorbs air contaminants from the environment; c) after / during the adsorption of air contaminants by the adsorbent filter (2), ROS are released from the ROS generator (3) for decomposition of air contaminants and rejuvenation of the adsorbent filter (2). The apparatus can operate without power supply and creation of disturbance like airflow and noise during adsorption process.

Description

technical field [0001] The present invention relates to air purification, and more particularly, to a method and apparatus for air purification. Background technique [0002] Now, the problem of indoor air quality is more and more concerned by people, because it is one of the culprits that endanger human health. Air pollutants, such as total volatile organic compounds (TVOC), ammonia, hydrogen sulfide, bacteria and viruses, will endanger human health. These problems urgently need to be resolved. [0003] US Pat. Nos. 7,473,074 and 5,042,457 disclose methods for injecting fresh air to effectively dilute air pollutants to maintain indoor air quality. However, access to fresh air may be difficult due to location constraints, especially in environments where it is difficult to install air ducts and airflow generating devices. Furthermore, this approach does not eliminate air pollutants, but rather transfers them to other areas, which may end up causing worse air problems. ...
