Abstract

The utility model relates to a structure for an indoor air purifying sterilizer. The utility model is characterized in that the left end of a casing is provided with an air inlet, and the right end is provided with an air outlet hole; a primary filter, a plasma generator, an ultraviolet decomposer, an electrothermal decomposer, an anion generator and an axial flow fan are arranged in the casing from left to right in turn. The utility model integrates purification, sterilization and air negative ionization together. The utility model has the advantages of high purification efficiency, good sterilization effect and low energy consumption.

Description

The indoor air purification sterilizer

The utility model relates to gas purification technique.

At present, indoor air purification is still using technology such as charcoal absorption, Electrostatic Absorption and negative aeroionization.Though the use of these technology is to the purification of indoor air pollutants, the improvement of IAQ has certain effect and effect, but its shortcoming is thoroughly to decompose, to remove the poisonous and harmful substance in the room air, purify not thoroughly, easily produce secondary pollution and can not carrying out disinfection room air.

Recently, the someone proposes to purify the air of a room with discharge of plasma in low temperature, but the shortcoming that this technology exists is: if adopt low pressure discharge, then purification efficiency is low, but also can not sterilize, sterilize sky; If the employing electrion though can improve some purification efficiencies, also can produce toxic gas-ozone simultaneously, this will cause the secondary pollution of indoor environment.

The purpose of this utility model, a kind of not only can efficiently purifying the air of a room will be provided exactly, and can kill microorganism in the room air effectively, and in room air, give off the negative ionization gas that do not contain ozone, the indoor air purification sterilizer.

Below in conjunction with accompanying drawing, the utility model is elaborated.

Accompanying drawing 1 is a structure chart of the present utility model.

Structure of the present utility model is seen accompanying drawing 1: the left end at insulation crust (15) has air admission hole (1), Right-hand member has venthole (8); Primary filter (2), plasma from left to right successively in shell (5) Body generator (3), Ultraviolet device (4), electrothermal decomposition device (5), anion generator (6), axle Flow fan (7). The jagged electrode of single face is housed in the plasma generator of the present utility model (3) (9) and grid electrode; Two-sided jagged electricity is housed in the anion generator of the present utility model (6) The utmost point (13) and metallic plate electrode (14).

During work, connect with the mains, the utility model under the effect of axial flow blower (7), room air By primary filter (2), elimination is bigger particulate pollutant (such as floating dust etc.) wherein by air admission hole (1); Air through primary filter flows into plasma generator (3), because plasma generator (3) is logical Cross high voltage direct and banish electricity generation low temperature plasma, wherein contain high energy electron, free state oxygen atom, Ozone and negative oxygen ion, pollutants in air are decomposed into harmless under the effect of high energy electron Material; The pollutant that is not decomposed lotus under the effect of DC electric field powers on, with air-flow to collector Mobile, be collected at last the utmost point and collect, the ozone of discharge generation and hydrone effect generate the oxidisability utmost point Strong hydroxyl (OH), these ozone and hydroxyl can be killed microbes in air, play sterilization Effect. The air that comes out from plasma generator (3) is the pure air that contains ozone, again Through Ultraviolet device (4) and electrothermal decomposition device (5), with remaining ozone decomposed, to eliminate secondary Pollute; Finally by negative stream electronic generator (5). Room air is through so filtration of multiple tracks, namely by only Change and sterilized.

The utility model has the advantages that: integrate purification, sterilization and negative aeroionization, and also the purification efficiency height, Disinfection Effect is good, and energy consumption is little and price is low.The utility model has fabulous application prospect.
