KR-20260066264-A - Indoor air purification device equipped with plasma ion sterilizer

Abstract

The present invention relates to an indoor air purification device equipped with a plasma ion sterilizer capable of purifying indoor air while simultaneously removing pollutants contained in harmful gases of indoor dust through plasma ions, and having a sterilization function. The device comprises: an intake fan configured in an intake section to draw in indoor air; a first mesh demister that removes and discharges oil, fine dust, and particulate matter contained in the air drawn in through the intake fan; a first plasma ion sterilizer that receives the air passing through the first mesh demister and generates primary OH radicals and ion electrons to oxidize and remove harmful gases contained in the air; a first adsorbent that receives the air from which harmful gases have been removed through the first plasma ion sterilizer and adsorbs and removes malodorous components contained in the air; a second plasma ion sterilizer that receives the air from which malodorous components have been primarily removed through the first adsorbent and generates OH radicals and ion electrons to oxidize and remove residual harmful gases contained in the air; and a device that receives the air from which harmful gases have been removed through the second plasma ion sterilizer and removes malodorous components remaining in the air. It is characterized by comprising a second adsorbent that removes by secondary adsorption, and a second mesh demister that receives air from which nitrogen gas has been removed through the second adsorbent, removes residual oil, fine dust, and dust contained in the air, and discharges purified air.

Description

Indoor air purification device equipped with plasma ion sterilizer The present invention relates to an indoor air purification device, and more particularly to an indoor air purification device equipped with a plasma ion sterilizer capable of collecting fine dust inside an indoor space and treating harmful gases. As air pollution intensifies, it is becoming increasingly difficult to breathe clean air. With various pollutants present not only outdoors but also indoors, situations where indoor air quality deteriorates frequently occur. When outdoor air pollution levels are high, ventilation through windows is also not recommended. To ensure clean air, it is necessary to consider both indoor and outdoor conditions, and filtering of incoming air is also required. Recently, as modern people spend the majority of their time indoors in places such as public buildings, underground facilities, and offices, interest in indoor air quality is increasing in consideration of its impact on the human body. Furthermore, the main factors known to pollute indoor air quality are particulate matter, such as fine dust, asbestos, and soil dust, and gaseous chemicals, such as formaldehyde and volatile organic compounds. Among these, fine dust and volatile organic compounds have adverse effects on health when exposed to the human body. Previous indoor air purification systems were limited to simply filtering and separating foreign substances, and had the problem of being unable to deal with very small foreign substances or airborne bacteria and viruses. FIG. 1 is a schematic diagram showing the configuration of an indoor air purification device equipped with a plasma ion sterilizer of the present invention. FIG. 2 is an installation diagram of an indoor air purification device equipped with the plasma ion sterilizer of FIG. 1 installed indoors. FIG. 3 is a schematic diagram showing the configuration of the plasma ion sterilizer of FIG. 1. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. Note that in the attached drawings, identical components are indicated by the same reference numerals whenever possible. Furthermore, detailed descriptions of known functions and configurations that may obscure the essence of the present invention will be omitted. For the same reason, some components in the attached drawings may be exaggerated, omitted, or schematically depicted. Furthermore, throughout the specification, when a part is described as “comprising” a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Also, throughout the specification, the term “on” means being located above or below the subject part, and does not necessarily mean being located on the upper side with respect to the direction of gravity. In the embodiments of the present invention, unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in the embodiments of the present invention. Furthermore, in order to highlight the technical features of the present invention, the illustration and description of certain configurations, such as general devices, configurations, or apparatuses applied in the same technical field as the present invention, may be omitted in the drawings attached to the present invention. Additionally, for the same purpose, the illustration of certain configurations may be enlarged, excessively emphasized, reduced, or omitted; however, it is obvious that such illustration does not limit the scope of the rights of the present invention. Before describing the present invention, it should be noted that the drawings highlight the configuration and form of the key parts, and that the proportions and shapes may differ slightly from the actual ones.
