Embodiment Construction

[0042] Reference attached figure 1 with 2 , shows an air cleaning device according to a first aspect of the present invention, said air cleaning device comprising a housing 1 having a flow channel 2 , an air inlet 4 entering the flow channel 2 and an air outlet 6 leaving the channel 2 . An airflow generator in the form of a fan or impeller 20 is provided for driving air through the housing 1 . As a safety measure, a grille (not shown) is provided across the air inlet 4 to prevent accidental contact with the impeller during operation. The power supply (not shown) can be a proprietary product, but should be able to provide 12-25Kv, 10-30KHz power.

[0043] figure 1 The athermal plasma filter, indicated generally at 30 in the center, comprises an anode or high voltage electrode 31, a dielectric 32, and a cage-like porous mesh 33 which serves as both the cathode and the end of the reaction chamber.

[0044] The anode 31 comprises a reticulated (three-dimensional porous) conducti...

Abstract

An apparatus for the decontamination of air, the apparatus comprising a housing (1) having an air inlet (4) and an air outlet (6) with an air passage (2) there between, means (20) for directing a stream of air through the housing, the housing containing a non-thermal plasma cell (30), an ultraviolet emitting device (40) and an ozone depletion catalyst (42), the non- thermal plasma comprising an anode (32), a dielectric (32) and a cathode (33), the cathode being in the form of a meshed enclosure which surrounds the ultraviolet emitting device and ozone depletion catalyst to form a reaction chamber and Faraday cage. The non-thermal plasma cell may also be provided as a columnar cell for forming an array of cells and the dielectric may comprise water droplets to improve the efficiency of the device.

Description

technical field [0001] The present invention relates to an improved device for air and surface purification. Background technique [0002] Air purity and the ability to consistently remove airborne contaminants are very important, especially in environments considered sterile or hygienic, such as hospitals and kitchens. It is also beneficial to have clean air in doctors' operating rooms as well as in the work environment, which makes it difficult for germs and diseases to spread. [0003] In addition to microbial contaminants, chemical gases or vapors can pose serious hazards as by-products of industrial processes or as malicious attacks of terrorism or chemical warfare. [0004] The applicant's earlier patent (EP1799330) provides an effective method, and the active component is hydroxyl (OH), which is second only to fluorine as an oxidized species, but its advantage is that it has no obvious toxicity to higher organisms, but it is harmful to pathogens. Germs and viruses a...
