DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a method and an apparatus carrying out deodorization, odor-removal and disinfection by using ozone.
BACKGROUND ART
Deodorization and odor-removal by using ozone are frequently utilized. Free-hydroxyradical produced by reaction between ozone and water molecule decomposes various odorous substances, especially malodorous substances such as ammonia and isovaleric acid etc. to provide deodorization and odor-removal effects. The free-hydroxyradical is produced by methods (1) ozonolysis caused by ultraviolet radiation, (2) hydrogen peroxide decomposition caused by ultraviolet radiation, (3) ozonolysis caused by hydrogen peroxide catalyst etc., and is produced efficiently by the method (3) in particular.
Incidentally, the above-mentioned method (3) has so far been carried out by putting a matter to be treated into aqueous hydrogen peroxide and making ozone bubble in the aqueous hydrogen peroxide. In this method, however, it has been unable to deodorize and remove odor from a large-scaled matter, and an efficiency has been bad.
DISCLOSURE OF THE INVENTION
A purpose of this invention is to provide a method and an apparatus which can carry out a deodorization/odor-removal work and further a disinfection work even on a large-scaled matter such as a room etc. effectively and efficiently.
A first invention of this application is characterized by that, in a method carrying out a deodorization/odor-removal/disinfection work on an object, ozone is produced and at the same time aqueous hydrogen peroxide is produced in an atomized state, the both are made contact each other and then made contact with the object.
According to the above-mentioned first invention, a density of the ozone contacting with the aqueous hydrogen peroxide under atomized state becomes large, and a reaction between the ozone and water content is enhanced owing to catalyst action of hydrogen peroxide, so that the free-hydroxyradical can be formed efficiently. Consequently, a deodorization/odor-removal/disinfection effect can be improved. Further, since the ozone and aqueous hydrogen, peroxide under atomized state contact each other while being dispersed, they reach widely every nook and corner to form the free-hydroxyradical. Therefore, the deodorization/odor-removal/disinf ection work can be carried out over a wide range every nook and corner. In addition, since the required reaction is only to produce the ozone and the aqueous hydrogen peroxide under atomized state simultaneously, its workability is good.
In addition to the above first invention, the following constructions may be used. peroxide under atomized state are made contact. According to this method, the deodorization/odor-removal/disinfection work can be carried out only on a desired spot in a concentrated manner. Further, since the ozone and the aqueous hydrogen peroxide can be utilized for the deodorization/odor-removal/disinfection work only on a desired spot so as to eliminate wasteful consumption of them, an increase in a raw material cost can be controlled. Moreover, since the free-hydroxyradical can be provided just in front of the desired spot, the deodorization/odor-removal/disinfection effect can be improved. residual ozone is recovered and decomposed. According to this method, the residual ozone at a site where the deodorization/odor-removal/disinfection work is carried out can be decomposed in an early stage and an entrance to the site can be accomplished in an early stage.
A second invention of this application is characterized by that, in an apparatus carrying out a deodorization/odor-removal/disinfection work of an object, there are equipped an ozone generator, an ozone blow-off mechanism which blows generated ozone from a blow-off port, a device which atomizes aqueous hydrogen peroxide, and an aqueous hydrogen peroxide blow-off mechanism which blows the atomized aqueous hydrogen peroxide from a blow-off port.
According to the above second invention, the method of the foregoing first invention can be realized by a simple constru
