Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ozone sterilizing / deodorizing facility for efficiently sterilizing / deodorizing a plurality of deodorizing treatment spaces.

[0002]

2. Description of the Related Art As is well known, ozone gas (O ₃ ), which is an allotrope of oxygen, has strong sterilization and oxidative decomposition powers. Therefore, by utilizing these properties, an arbitrary deodorizing treatment space is disinfected and deodorized. That is being done.

[0003] For example, as shown in FIG. 2, after a gap is opened between the windows and doors of the deodorizing treatment space A as described above, an outlet pipe a provided on the ceiling thereof is referred to as an ozonizer or the like. Ozone gas generated by the ozone generator b is blown out together with air sent from a blower c such as a blower to fill the space A for a certain period of time, thereby disinfecting the space A and oxidizing and decomposing deodorant components to deodorize.

[0004]

Incidentally, a building having a plurality of such deodorizing treatment spaces (rooms), such as a sludge treatment plant, an agricultural settlement drainage plant, a sewage treatment plant, a food factory, a nursing home, a hospital, etc., is described above. In order to sterilize and deodorize with such ozone gas, it is necessary to separately provide an ozone generator b and a blower c, and an ozone decomposition catalyst for decomposing excess ozone gas for each deodorization treatment space,
There is a disadvantage that the equipment cost is increased.
In other words, in the deodorizing treatment space as described above, since the concentration of the offensive odor component is not uniform, and there are cases where there are persons such as a workplace or a hospital ward, it is necessary to perform safe and efficient sterilization and deodorization. This is because it is necessary to efficiently supply ozone and air at a concentration suitable for the concentration of the malodorous component in the deodorizing treatment space.

Accordingly, the present invention has been devised in order to effectively solve such a problem, and an object of the present invention is to provide a novel ozone sterilizer capable of efficiently sterilizing and deodorizing a plurality of deodorizing treatment spaces.・ Provide deodorizing equipment.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an ozone pipe for flowing ozone gas generated by an ozone generator and an air pipe for flowing air supplied from a blower in a plurality of deodorizing treatment spaces. And a flow control valve for controlling the flow rates of the ozone gas and the air supplied to the respective deodorizing treatment spaces is provided near each of the outlets of the ozone pipe and the air pipe.

Therefore, even if a plurality of ozone generators and blowers are not used, if there is a set of ozone generators and blowers, a flow control valve provided near each outlet of each ozone pipe and air pipe is controlled. By adjusting the flow rate, ozone having a concentration suitable for each deodorizing treatment space and air having a suitable amount can be separately supplied.

[0008] Further, by joining the outlets of the ozone pipe to the downstream side of the flow control valve of the paired air pipe, the air whose flow rate has been adjusted and the ozone gas are sufficiently mixed. Thus, the ozone gas can be uniformly diffused into each deodorizing treatment space.

[0009]

Next, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows an embodiment of an ozone sterilization / deodorization facility according to the present invention. In the figure, reference numeral 1 denotes a plurality of sewage treatment plants, factories, hospitals and the like (three in this embodiment). 2) is a building in which deodorization processing spaces (rooms) 1a, 1b, 1c are connected, 2 is an ozone generator that generates ozone gas from silent oxygen or the like from oxygen in the air, and 3 is a blower that sucks in air and blows air.

As shown in the figure, first, an ozone pipe 4 for sending generated ozone is connected to the ozone generator 2, and the downstream of the ozone pipe 4 is branched into a plurality of outlets. Is each deodorization processing space 1a, 1b,
1c. On the other hand, an air pipe 5 for sending the sucked air to the blower 3 is also connected, and the downstream of the ozone pipe 4 is branched into a plurality of branches, and the outlets thereof are similarly formed in the deodorizing processing spaces 1a and 1b. ,
1c so as to face the ceiling. Therefore, the ozone gas and air supplied from the pair of ozone generator 2 and the blower 3 pass through the ozone pipe 4 and the air pipe 5, respectively, and are separately supplied to the deodorization processing spaces 1a, 1b, 1c. Has become.

The ozone pipe 4 and the air pipe 5
Air flow control valves V ₁ , V ₂ , V ₃ for adjusting the flow rate of air and ozone gas flow control valves v ₁ , v ₂ , v ₃ for adjusting the flow rate of ozone gas are provided in the vicinity of each outlet. These ozone gas flow rate control controls v ₁ , v ₂ , v ₃
The openings (flow rates) of the air flow control valves V ₁ , V ₂ , and V ₃ are freely controlled by a flow control device 6.

Next, an example of a sterilization / deodorization method using the sterilization / deodorization equipment configured as described above will be described. In this example, the purpose is mainly to remove the malodorous component due to ozone, and the amount of the malodorous component will be described assuming that the deodorizing treatment space 1a <1b <1c. Further, each outlet of the ozone pipe 4 is arranged so as to join the air pipe 5 downstream of the air flow control valves V ₁ , V ₂ , V ₃ .

First, when the blower 3 is driven, the sucked air is diverted through the air pipe 5, and then flows into the respective deodorizing processing spaces 1a, 1b, 1c. When the ozone generator 2 is driven at the same time, the high-concentration ozone gas obtained here is diverted through the ozone pipe 4, and then together with the air flowing through the air pipe 5, the respective deodorization processing spaces 1a, 1b, 1c, the deodorizing treatment spaces 1a, 1b, 1c are deodorized. At this time, the deodorizing space 1a as described above, 1b, since the concentration of the malodorous components of 1c is 1a <1b <1c, ozone gas flow rate control valve by a flow control device _{6 v 1, v 2, v} 3 and the opening of the air flow control valve _{V 1, V 2, V 3} v 1 <v 2
<With v _3, so that the ozone gas concentration corresponding to the concentration of the malodorous components can be efficiently supplied. Therefore, adverse effects due to excessive ozone gas supply, for example, even when there are sick persons or workers in the deodorizing treatment space, can be prevented beforehand, and high concentration malodorous components are easily oxidized and decomposed. It becomes possible. Moreover, excess ozone gas is not exhausted, so that an ozone decomposition catalyst or the like becomes unnecessary, and cost reduction can be achieved. still,
Here, ozone gas and air are supplied to each of the deodorizing treatment spaces 1a and 1a.
Since ozone gas has a higher specific gravity than air, the ozone gas alone flows into each of the deodorizing treatment spaces 1 and b.
a, 1b, and 1c, are settled as they are, and stay at the bottom of each deodorizing treatment space 1a, 1b, 1c,
This is because they do not diffuse uniformly. Also, as shown in the figure,
By joining the respective outlets of the ozone pipe 4 to the downstream side of the flow control valves V ₁ , V ₂ , V ₃ of the air pipe 5 forming a pair, the air and ozone gas whose flow rates have been adjusted can be sufficiently increased. The ozone gas is mixed and blown out from one outlet at the same time, so that the ozone gas is uniformly diffused together with air into the respective deodorizing treatment spaces.

As described above, the present invention supplies ozone gas and air obtained from a pair of ozone generators and a blower to a plurality of deodorizing treatment spaces at an arbitrary flow rate by using an ozone pipe and an air pipe. Therefore, the supply of ozone gas corresponding to the degree of the malodorous component and the purpose of deodorization can be finely performed.

[0016]

In summary, according to the present invention, if at least one set of ozone generator and blower is provided, ozone gas supply corresponding to the degree of malodorous components and the purpose of deodorization should be performed in a fine and sufficient manner. Therefore, not only can the cost be reduced, but also the adverse effects of excess ozone gas can be prevented. In addition, since no excess ozone gas is generated, it is not necessary to separately provide an ozone decomposition catalyst or the like, and excellent effects such as reduction in cost can be achieved.
