Air purifier

Abstract

To provide an air cleaner with which discharging sounds are reduced and the generation of noise can be prevented as well. An air blowing fan 12, an optical catalyst module 14 and an ozone decomposing catalyst filter 16 are arranged on an air blowing pass 13 and air cleaning is performed by rerforming discharging with pulses having rising width for 10 mu sec and discharging frequency of >=10 kpps.

Description

technical field The present invention relates to an air purifying device for purifying the air by decomposing odor components and harmful substances contained in the air. Background technique In recent years, due to the development of residential buildings to a high degree of enclosure, outdoor air pollution tends to be constant, and the requirements for improving the air quality of living spaces are increasing. Among the air quality, there is a great need to reduce the odor of tobacco smoke and metabolic odor in the surrounding environment, and to remove harmful components (represented by VOC, etc.) emitted from building materials. To meet these requirements, conventionally, methods of deodorizing with an adsorbent represented by activated carbon or reacting odor components with other chemical components to change the properties of the odor to reduce the odor have been used. However, the deodorization and removal of harmful components using the above-mentioned prior art...

AI Technical Summary

Problems solved by technology

On the other hand, the method of making the odor components react with other chemical components and changing the properties of the odor to reduce the odor has the problem that it is troublesome to replace the adsorbent after the chemical components are consumed, and the chemical components are discharged into the air. It is difficult to control the emission in an odorous environment

In addition, in order to decompose and remove harmful components such as formaldehyde, a catalytic reaction with a high oxidation-reduction potential must be performed, but there is a problem that the oxidative decomposition with ozone does not achieve complete decomposition, but stops at the middle of the decomposition of the product. stage, can not achieve complete harmless

In addition, there is a problem that due to the different conditions of high-voltage discharge, noise may sometimes be generated, and corresponding measures must be taken
