Hereinafter, a method of operating the apparatus of the present invention will be described in detail.

1) Step of adding chlorine dioxide to the reaction tank (1)

First, chlorine dioxide is sprayed / sprayed in an appropriate amount according to the size of the reaction tank through a chlorine dioxide (ClO 2 ) spraying / jetting port (2) formed in the upper part of the reaction tank (1). After a predetermined time has elapsed, the chlorine dioxide solution stored in the lower portion of the reaction tank 1 may be circulated by spraying / spraying the chlorine dioxide (ClO 2 is supplied and sprayed / sprayed.

The concentration of chlorine dioxide is measured by measuring the concentration of the discharged gas according to the size of the space used and the environment and adjusting it to an appropriate concentration.

For example, chlorine dioxide solution 1,000 mg / l L = 1 ppm and chlorine dioxide gas 2.8 mg / l m 3 = 1 ppm.

2) Inhalation phase of contaminated air

Next, outside air from which various dusts and floating matters are removed, or contaminated air from the purification required space 8 is sucked into the reaction tank 1 through the air inlet fan 32 through the filter 31.

The outside air or contaminated air sucked into the reaction tank is primarily purified by the chlorine dioxide (ClO 2 ) solution stored in the lower portion of the reaction tank 1 through the acid gas valve 34.

3) Sterilization, disinfection and deodorization step inside the reaction tank (1)

Then, the external air and the contaminated air sucked into the reaction tank 1 are sterilized, disinfected and deodorized in the second stage by spraying / spraying chlorine dioxide (ClO 2 ) in the reaction tank 1.

4) Supply step of purified air

The purified air and the chlorine dioxide gas in the reaction tank 1 are naturally transferred to the air supply port 4 formed in the upper part of the reaction tank 1 and moved to the purification required space 8 through the air supply port 4 .

      At this time, purified air and chlorine dioxide gas purified by sterilization, disinfection and deodorization are supplied according to the size and environment of purification space, and when it is necessary to control the concentration of the input amount or when it is no longer necessary to use it, (41), the timer (42), and the supply fan (43) so that the supply pipe can be closed or discharged to the outside.

A moisture removal filter 47 is provided between the air supply port 4 and the purification space 8 or between the alkaline reaction tank 6 and the purification space 8 so as to be supplied to the purification space 8 The moisture of the purified air can be removed.

5) Inlet and feed into the alkaline reaction tank 6

As another embodiment of the present invention, the air purified in the reaction tank 1 may be introduced into the alkaline reaction tank 6 to remove the odor of the acids (organic acid and inorganic acid) and the multi-reflux substances not removed in the reaction tank 1 have.

Of course, since chlorine dioxide is also neutralized, if it is desired not to introduce chlorine dioxide-containing air into the room, that is, if pure chlorine dioxide not containing chlorine dioxide (ClO 2 ) gas is desired to be supplied, It is possible to supply only the indoor air.

In this case, as the alkaline solution, caustic soda and the like are supplied. In the supply of the air containing chlorine dioxide (ClO 2 ), the acid gas valve is connected to the lower part of the alkaline reaction tank 6 to generate air bubbles have.

6) Indoor air purification stage

The purified air that has passed through the reaction tank 1 or the reaction tank 1 and the alkaline reaction tank 6 can be sterilized, disinfected, deodorized, or otherwise contaminated air flowing into the purification required space 8, , Or only purified air can be supplied, and it is also possible to supply timely and quantitatively with a timer if necessary.

Since the chlorine dioxide gas has a very fast diffusion rate in the air, the chlorine gas can be diffused evenly in a certain concentration in a short time, and the chlorine gas can be diffused through the blower to the air conditioning system such as the air conditioner and the duct, It is possible to sterilize and disinfect space and air.

7) Steps to replenish and replace chlorine dioxide

It is always possible to replenish the chlorine dioxide solution through the chlorine dioxide (ClO 2 ) inlet port 50. When the dissolved concentration of the chlorine dioxide is lowered through the chlorine dioxide concentration meter attached to the circulation pump, Some of the existing solution can be drained, new chlorine dioxide solutions can be replenished, or all can be replaced.

8) Emission and inspection phase

If it is necessary to replace after use, or if it is no longer operating, the residual reaction solution can be discharged through the discharge valve.
