Title:
空気消毒装置及びその使用方法
Document Type and Number:
Japanese Patent JP6969017
Kind Code:
B2
Abstract:
In a method and apparatus (10) for air disinfection a unipolar corona discharge zone (26) is formed between an ionizing portion (15) of a first electrode (14) and a non-ionizing second electrode (18) by applying high DC voltage (22′, 22″) across the first and second electrodes and water molecules in an air flow (25) conveyed through the corona discharge zone are converted to hydrogen peroxide molecules. An electric field (27, 27′, 27″) is generated across the air flow close to the corona discharge zone for preventing ions escaping from the corona discharge zone into the atmosphere. This allows a higher corona discharge current to be applied than would be permitted if ions were able to escape into the atmosphere, which results in a higher yield of hydrogen peroxide and increases the efficiency of disinfection. It also helps to prevent dust from settling on the ionizing portion (15).
