Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor fumigation method which is regularly performed in hospitals and clinics for sterilization.

[0002]

2. Description of the Related Art Generally, in medical facilities such as hospitals and clinics, regular sterilization and disinfection are carried out in order to prevent secondary infection such as bacteria and pathogenic bacteria. As for this sterilization and disinfection method, various methods such as a method by heating, a method by chemicals, a method by ultraviolet rays, etc. are used in the case of clothes and limbs, but when sterilizing and disinfecting the whole room, so-called fumigation Method is used.

As a conventional indoor fumigation method, for example, a window, a door or the like in the room is pasted to seal the room, and then a bactericide such as formalin (trade name: formaldehyde) is sprayed into the room to fumigate for a whole day and night. After that, since the formalin itself is a harmful substance to humans, it is neutralized with a neutralizing agent such as ammonia for a predetermined time.

[0004]

However, in such a conventional fumigation method, as described above, the interior of the room must be hermetically sealed by using the tape tape or the wet newspaper to seal the windows and doors in the room. Since it has to be done, the work is troublesome. In addition, it is difficult to match the amount of ammonia for neutralizing formalin, and the odors of these drugs adhere to the room, forcing them to feel uncomfortable for a while.

Therefore, the present invention has been devised in order to effectively solve the above-mentioned problems, and its main purpose is to easily and easily handle chemicals which are difficult to handle, and troublesome work such as sticking. A novel indoor fumigation method capable of performing indoor fumigation.

[0006]

In order to achieve the above object, the present invention installs an ozone generator and an ozone decomposer in a room, and fumigates the room for a predetermined time with ozone generated from the ozone generator. The indoor ozone generated by the ozone decomposing device is decomposed into oxygen and exhausted to the outside of the room to bring the inside of the room into a negative pressure state.

That is, according to the present invention, indoor fumigation is performed by using ozone which is easily decomposed into odorless and harmless oxygen instead of the chemical such as formalin, which has been conventionally performed by using chemicals such as formalin. Is made easy.

[0008]

According to the present invention, the interior of the room is sterilized by the ozone generated from the ozone generator, and at the same time, the ozone in the room is decomposed into odorless and harmless oxygen and exhausted to the outside. Therefore, the conventional neutralizing agent becomes unnecessary. In addition, the exhaust of the ozone decomposing device causes the indoor pressure to become a negative pressure state than the outdoor pressure,
Ozone in the room no longer leaks through the gaps between the windows and doors, eliminating the need for the troublesome pasting work.

[0009]

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows an indoor fumigation apparatus used in the method of the present invention. As shown in the figure, this indoor fumigation apparatus is an ordinary hospital room or the like having windows and doors formed therein, and is composed of an ozone generator 1 and an ozone decomposer 2 which are placed in the room to be fumigated. .

As shown in FIG. 2, the ozone generator 1 has a container 4 in which an intake port 3a for sucking indoor air and an exhaust port 3b are formed, and the indoor air is sucked into the container 4 and exhausted. The air pump 5, the oxygen enricher 6 for decomposing the air sucked by the air pump 5 into oxygen and nitrogen, and the ozone generator 7 for generating ozone (O ₃ ) are continuously connected to each other. It is housed. The suction port 3a is provided with an ozone decomposer 8 containing a filter-like ozone decomposition catalyst to prevent the ozone decomposer 8 from being sucked into the ozone container 4 in the room. That is, as is well known,
This is because this ozone has a strong oxidizing power as well as a sterilizing power, and if this ozone flows into the container 4 as it is, the air pump 5 made of iron or the like and the oxygen enricher 6 are oxidized and corroded. Therefore, the container 4 itself is also made of a material such as stainless steel having a high anticorrosion property against ozone, and is formed in a hermetically sealed state so that ozone in the room does not flow in from any place other than the suction port 3a provided with the ozone decomposer 8. Has been done. The ozone generator 7 is a so-called ozonizer, which has a discharge electrode therein and ionizes oxygen sent from the oxygen enricher 6 by high-pressure discharge to generate ozone. The ozone generator 7 and the exhaust port 3b are connected to each other by an exhaust pipe 10 made of a material such as stainless steel having a high corrosion resistance to ozone so that ozone generated by the ozone generator 7 does not leak into the container 4. Moreover, the exhaust port 3b guides the vehicle indoors. Further, the oxygen enrichment machine 6 is provided with a nitrogen exhaust pipe 6a for evacuating nitrogen, which is branched from this, and the end of the nitrogen exhaust pipe 6a faces the room to exhaust the nitrogen into the room. .

On the other hand, the ozone decomposing device 2 decomposes ozone in the room into harmless and odorless oxygen and exhausts it to the outside.
As shown in FIG. 3, an inlet 12 and an outlet 13 are formed in a decomposition container 11 made of a member having high corrosion resistance to ozone, such as stainless steel, like the container 4 of the ozone generator 1, and inside the decomposition container 11. Similarly to the ozone generator 1, an ozone decomposer 8 in which an ozone decomposition catalyst is accommodated and a blower fan 14 are accommodated. An exhaust pipe 15 is connected to the exhaust port 13, and an end of the exhaust pipe 15 penetrates a wall surface to be fumigated and faces the outside of the room.

Next, an embodiment of the method of the present invention will be described using this indoor fumigation apparatus.

First, as shown in FIG. 1, this indoor fumigation apparatus is installed in a room where fumigation is to be performed, and medical equipment and the like that are easily oxidized in the room are taken out of the room. This is to prevent medical equipment that is easily oxidized from being oxidized and corroded by ozone. Next, when the ozone generator 1 of this indoor fumigation apparatus is operated, as shown in FIG. 2, the air in the room is sucked into the container 4 from the suction port 3a by the air pump 5, and oxygen is converted into oxygen by the oxygen enricher 6. It is decomposed into nitrogen, and the nitrogen is exhausted into the room again through the nitrogen exhaust pipe 6a. On the other hand, the oxygen generated by the oxygen enricher 6 is sent to the ozone generator 7,
Here, after being ionized by high-pressure discharge to become ozone, it is discharged into the room through the exhaust pipe 10 and the exhaust port 3a. Then, as shown in FIG. 1, the ozone released into the room is returned to the room to sterilize and disinfect the room.
It is desirable that the ozone generator 1 be installed at a position as far as possible from the ozone decomposer 2 or be sprayed along the wall surface so that the generated ozone is sufficiently diffused in the room.

If the ozone diffuses into the room to some extent in this way, then the fan 14 of one of the ozone decomposing devices 2 is driven, and the ozone in the room is sucked into the decomposition container 11 as shown in FIG. When it is sucked into the decomposition container 11 from the mouth and is decomposed into oxygen to make it non-toxic and odorless when passing through the ozone decomposition catalyst layer 8, it is exhausted to the outside from the exhaust port 13 through the exhaust pipe 14. . As a result, the inside of the room is in a negative pressure state, and as shown in FIG. 1, outdoor air flows into the room through the gap S between the windows and doors, and ozone diffused into the room leaks out through the gaps S between the windows and doors to the outside. Will disappear.

As described above, according to the method of the present invention, the interior of the room is sterilized and disinfected by the ozone generated from the ozone generator, and at the same time, the ozone in the room is decomposed into odorless and harmless oxygen and exhausted to the outside. Therefore, the conventional neutralizing agent becomes unnecessary. In addition, the exhaust of this ozone decomposing device causes the indoor pressure to become a negative pressure state than the outdoor pressure, so that ozone in the room where the window or door is formed does not leak out of the room, which is troublesome as in the past. No need for pasting work.

In the present embodiment, the example in which the ozone decomposing device is driven after the ozone generating device is driven has been described. However, these may be driven simultaneously or first, and in this case, further. The ozone leakage effect can be improved. In addition, an ozone concentration sensor, a timer, or a control device is installed in the ozone generator or ozone decomposer to set the optimum fumigation method and time according to various factors such as room volume or ozone concentration, and automatically control this. Of course, you may do so.

[0018]

In summary, according to the present invention, since ozone which is harmless and easily deodorized is used in place of the conventional chemicals, a neutralizing agent as in the conventional case is not required, and ozone in the room is used as a window or door. Since there is no leakage from the gap, there is an excellent effect that fumigation work can be performed easily without the need for the conventional troublesome eye-pasting work.
