Abstract

A sterilizing component removal device which reduces a sterilizing component sprayed in a working chamber having an outlet includes a sprayer which supplies, in an atomized manner, a liquid different from the sterilizing component into the working chamber.

Claims (21)

1. A sterilizing component removal device which removes a sterilizing component sprayed in a working chamber having an outlet, the sterilizing component removal device comprising:

a sprayer which is disposed in the working chamber and which supplies, in an atomized manner, a liquid different from the sterilizing component into the working chamber so as to promote gasification of the sterilizing component;

a liquid source for supplying the liquid to the sprayer; and

a sterilizing component source for supplying the sterilizing component to the sprayer,

wherein the sprayer sprays, in the working chamber, the liquid in the atomized manner separately from the sterilizing component.

2. The sterilizing component removal device according to claim 1 , wherein the sprayer supplies, in the atomized manner, the liquid which includes a substance which promotes gasification of the sterilizing component which is liquefied, into the working chamber.

3. The sterilizing component removal device according to claim 1 , wherein the sprayer supplies, in the atomized manner, the liquid which includes an active species which decomposes the sterilizing component, into the working chamber.

4. The sterilizing component removal device according to claim 3 , further comprising:

a plasma generator which generates plasma to generate the active species in the liquid stored in the liquid source.

5. A disinfection device comprising:

the sterilizing component removal device according to claim 1 ,

wherein the sprayer further supplies, in the atomized manner, the sterilizing component into the working chamber.

6. A disinfected environment maintaining system comprising:

the sterilizing component removal device according to claim 1 ;

the working chamber; and

an expulsion device which expels gas from the working chamber through the outlet.

7. The disinfected environment maintaining system according to claim 6 , further comprising a supply device which supplies gas into the working chamber.

8. The sterilizing component removal device according to claim 1 , wherein the sprayer sprays, in the working chamber, the liquid in the atomized manner, at a different time from a time when the sterilizing component is sprayed in the working chamber.

9. The sterilizing component removal device according to claim 1 , wherein the sterilizing component and the liquid are delivered to the sprayer separately from one another.

10. The sterilizing component removal device according to claim 1 , wherein the sprayer further comprises a first sprayer and a second sprayer.

11. The sterilizing component removal device according to claim 10 , wherein the sterilizing component is supplied to the first sprayer, and the liquid is supplied to the second sprayer.
