Air filtering apparatus

Abstract

In an air filtering apparatus including a gas-liquid contact member (5) disposed in a housing (2), an electrolytic water supply pipe (17) for dropping electrolytic water to the gas-liquid contact member and an air blowing fan (7) for blowing air to the gas-liquid contact member to which the electrolytic water infiltrates and blowing out the air to a room, a first sheet member (76) having water retentivity for distributing the electrolytic water dropped from the electrolytic water supply pipe to the gas-liquid contact member is disposed above the gas-liquid contact member, and the first sheet member is equipped with recess portions (76D) at which scale accumulates when hardness components in the electrolytic water precipitate as the scale, or cut-out portions (92) through which the electrolytic water is positively discharged when hardness components in the electrolytic water precipitate as scale and accumulates on the first sheet member.

Description

technical field [0001] The present invention relates to an air sterilizing device capable of removing airborne microbes such as bacteria, viruses, and fungi (hereinafter simply referred to as viruses, etc.). Background technique [0002] In general, for the purpose of removing viruses and the like, there has been proposed a sterilizing device that diffuses electrolyte mist in the air and makes airborne microorganisms directly contact the electrolyte mist to inactivate viruses and the like. [0003] Patent Document 1: JP-A-2002-181358 [0004] However, in the above-mentioned sterilizing device, although it can be effective in a use environment where the electrolyte mist in the form of particles is easy to reach, that is, in a small space, it can be used in a use environment where the electrolyte mist is difficult to reach, such as kindergartens, universities, middle and primary schools, etc. It is difficult to be effective in large spaces such as nursing care insurance facil...

Problems solved by technology

[0007] However, since the electrolyte solution contains hardness components (such as calcium ions), when the hardness components are precipitated as scale, the scale is deposited on the manifold as in the past, thereby hindering the water permeability of the manifold.

At this time, the electrolyte cannot be soaked into the entire gas-liquid contact parts, which will reduce the sterilization efficiency of the air
