DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for purifying air in a multi-person accommodation room, and a play room such as a pachinko parlor, a mahjong store, a disco, a hospital, a nursing home, or a meeting place, a waiting room, and a non-smoking room. Many people gather like vehicles,
It is effectively used for purifying indoor air in a room where the air becomes dirty with tobacco smoke and dust.

[0002]

2. Description of the Related Art As a conventional method of purifying air in a multi-person room, a method of replacing air by ventilating, a method of purifying air by circulating air with an air conditioner having a filter, and the like have been used. . As a method of purifying air, there are a method of installing a deodorizing / deodorizing device in a room, and a method of purifying air by using a deodorizing effect and a sterilizing effect of ozone. Ozone has an oxidative decomposition action and a neutralizing action for malodorous substances, and has an excellent deodorizing effect on many animal and plant organic or inorganic odorous substances.

As an ozone generator, for example, Japanese Patent Application Laid-Open
As described in JP-A-26293, a method in which oxygen in the air is ozonized by applying a high-voltage AC voltage between electrode plates coated with a flat metal and conducting a silent discharge, or 100 Using a transformer that boosts the volt alternating current to more than 5000 volts, applies a high voltage as a negative voltage pulsating current to the electrode section consisting of two or more electrode plates with a rectifier, generates silent discharge, and generates ozone There is a method to make it. There is also a method of generating ozone by ion wind (Japanese Patent Laid-Open No. 59-212630).

However, when the amount of generated ozone is large, not only the peculiar odor of ozone is strongly sensed,
It irritates the mucous membrane and adversely affects the human body. It is not safe to breathe long term air containing 0.1 ppm or more ozone.

[0005] Then, in order not to release a large amount of ozone,
Many air purifiers include an ozone generator and an ozone decomposing unit. For example, a closed room deodorizer disclosed in Japanese Utility Model Laid-Open Publication No. 55-142140 is composed of an electrode plate type ozone generator and a mesh container containing an ozonolysis reaction material, and the air sucked into the deodorizer is close to the ozone generator. After passing through the deodorization reaction space,
It is configured to be discharged outside the vessel via the ozonolysis reaction material.

In order to remove ozone generated by corona discharge and accompanying ion wind, an air purifier having an ozone removing member disposed downstream of the ion wind has been proposed (Japanese Patent Application Laid-Open No. Sho 59-193158). .

[0007]

In the above-mentioned ventilation method, the air exchange is performed with the outside air, so that the cost of cooling and heating is high. In the above-mentioned air conditioning method, a large amount of air is circulated in order to purify the air in the multi-person accommodation room. Because of this, there is a problem that the operating cost of the air conditioner is high. In the method of installing the above deodorizing / deodorizing equipment indoors,
Only in the vicinity of the device, there is an air purification effect, which is insufficient for use in a large room accommodating a large number of people, and the purification effect is also insufficient. In the above-described purification method using ozone, as described above, the generation of a large amount of ozone has a problem that the human body is uncomfortable or adversely affected. Therefore, the emission of ozone is suppressed. Therefore, the purification reaction by ozone is considered in the apparatus, and
Also in the method of JP-A No. 2140, a large amount of air must be circulated in the deodorizer, and there is a problem that the operating cost is increased as described above.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a method for purifying air in a multi-person accommodation room that makes use of the purifying action of ozone and does not adversely affect the human body. I do.

[0009]

According to the present invention, there is provided a method for purifying air in a multi-person room, comprising the steps of: providing a plurality of ozone generators at a high position in the multi- person room;
Several ozone decomposers are installed near the head of the body ,
Ozone is decomposed through air containing ozone . Further ozone decomposer position the residual ozone quantity of the chamber
It is desirable to keep the average below 0.1 ppm below the height .

[0010] In multiplayer accommodating chamber provided with a pachinko Yu technique device comprises an ozone generator in the ceiling or accessories or wall near the ceiling of the room, as provided ozone decomposer near the pachinko Yu TECHNICAL device This is a preferred embodiment.

[0011]

According to the present invention, an ozone generator is provided at a high position in a room, and an ozone decomposer is provided at a middle position or a relatively low position in a room. And purify the air. That is, when only acting in a small space in the device as in the prior art, only a small amount of air was purified, but in the present invention, ozone can be acted over a relatively large space, The effect of purifying ozone can be sufficiently exhibited. Therefore, air purification can be effectively performed even in a room with a large amount of air and accommodating a large number of people. Since ozone is heavier than air, an ozone generator is installed at the top of the room,
As it moves downward, it gradually purifies the air. While ozone is reduced and consumed in the process of falling, undecomposed ozone comes down. In order to prevent the adverse effects of ozone from affecting the human body, an ozone decomposer is provided near the height of the human body so that ozone is decomposed before being sucked into the human body.

The amount of residual ozone in the air treated by the ozone decomposer is 0.1 pp on average below the position of the ozone decomposer from the viewpoint of preventing adverse effects on the human body.
m or less. As an ozone generator,
As described above, there is a method in which gaseous oxygen or air is passed during high-voltage AC discharge to generate ozone by silent discharge.

As the ozone decomposer, a device that removes ozone by passing air containing ozone through a member obtained by attaching an ozone adsorbent or an ozone decomposer to a base material such as paper is used. Examples of ozone adsorbents include turpentine oil and cauliflower oil, which absorb ozone well. Activated carbon also adsorbs ozone well. Examples of the ozonolysis agent include manganese dioxide and a platinum catalyst. Note that the types of the adsorbent and the decomposing agent do not limit the present invention.
