【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、例えば食品・薬品工場、病院、劇場。[Detailed description of the invention] [Industrial application field] The present invention can be applied to, for example, food/drug factories, hospitals, and theaters.
映画館等のクリーンルームに適用される循環空気の殺菌
・除臭システムに関する。This relates to a sterilization and deodorization system for circulating air that is applied to clean rooms such as movie theaters.
従来、クリーンルーム内の空気は、その循環経路に設け

E P A)によって空気中の細菌やカビ類等が除去さ
れているが、高効率フィルタはその物理的特性上
■ ポアサイズが小さいため除去した菌の処理が不可能
。Conventionally, the air in a clean room has been passed through a high-efficiency filter (H
Bacteria and molds in the air are removed by EPA), but due to the physical characteristics of high-efficiency filters, the pore size is small, making it impossible to dispose of the removed bacteria.
■ フィルタ交換時における作業員の安全衛生面で問題
がある。■ There are health and safety issues for workers when replacing filters.
■ フィルタの廃棄方法等が確立されていない。■ There is no established method for disposing of filters.

く殺菌効果がなかった。There are problems such as these, and a more fatal problem is that it has no sterilizing effect on the clean room itself, that is, on the bacteria and mold that adhere to the inside walls and internal equipment of the clean room.
また、除具については活性炭などの脱臭触媒を充填した
脱臭触媒充填槽を用いて単独で脱臭を行なっているが、
このような単独の脱臭システムでは脱臭触媒の破過時間

するという問題があった。In addition, deodorization is carried out independently using a deodorizing catalyst filling tank filled with a deodorizing catalyst such as activated carbon.
In such a single deodorizing system, the breakthrough time of the deodorizing catalyst is short, so there is a problem that the regeneration cost and replacement cost of the deodorizing catalyst increase.

単独で用いていたため、脱臭効果が短いという問題があ
った。As mentioned above, in the past, high-efficiency filters (HEPA) were installed in the circulating air path of the clean room to remove bacteria and mold from the circulating air. It was not possible to remove the bacteria and fungi present. Furthermore, as for the removal tool, a deodorizing catalyst filling tank filled with a deodorizing catalyst such as activated carbon was used alone, so there was a problem that the deodorizing effect was short.
本発明はこのような問題点に鑑みてなされたもので、ク

ことを目的とするものである。The present invention has been made in view of these problems, and provides a circulating air sterilization and deodorization system that can enhance the sterilization effect in a clean room and in the circulating air itself, and in which the deodorizing effect of the deodorizing catalyst continues for a long time. The purpose is to provide the following.

路を設けたことを特徴とする。In order to achieve the above object, the present invention installs an ozonizer in the circulating air path of a clean room, and also installs a flow path switching valve and a deodorizing catalyst filling tank on the downstream side of the ozonizer, and the circulating air that has passed through the ozonizer. The present invention is characterized in that a bypass passage is provided for bypassing the deodorizing catalyst filling tank and returning the deodorizing catalyst to the clean room.

することができる。In the present invention, since the circulating air from the clean room passes through the discharge section of the ozonizer, bacteria and mold in the circulating air can be killed or suspended by the high-voltage electric field strength. Furthermore, since the circulating air that has passed through the ozonizer contains ozone, the deodorizing catalyst can be activated by ozone. Furthermore, by switching the circulation path of the circulating air to the bypass flow path side with a flow path switching valve provided on the downstream side of the ozonizer, the circulating air that has passed through the ozonizer is returned to the clean room by bypassing the deodorizing catalyst filling tank. Ozone can sterilize bacteria and mold that adhere to the inner walls and equipment inside the clean room.
以下、図面を参照して本発明の詳細な説明する。 Hereinafter, the present invention will be described in detail with reference to the drawings.

1との間に冷媒が流れるようになっている。FIG. 1 shows an embodiment of the present invention, in which 1 is a clean room, 2 is a circulation fan that circulates the air in the clean room 1, and 3 is an ozonizer provided downstream of the circulation fan 2. As shown in FIG. 2, this ozonizer 3 is constructed by arranging a plurality of anonide electrodes 22 inside a cylindrical cathode electrode 21, and circulates air from the circulation fan 2. As shown by the arrow, the water flows into the ozonizer 3 through the inlet duct 23, passes through the inside of the evaporating electrode 21, and flows out through the inlet duct 24. Note that a jacket 27 having a refrigerant inlet 25 and a refrigerant outlet 26 is provided on the outside of the cathode electrode 21, and this jacket 27 and the cathode electrode 2
Refrigerant is allowed to flow between 1 and 1.

A ternary post-composite oxide consisting of silicon and zirconium is filled as a deodorizing catalyst, and the circulating air leaving the ozonizer 3 is deodorized in a deodorizing catalyst filling tank 5 and then passes through a filter 6 to the clean room 1. It's starting to go back.

It is a total. The output of this ozone concentration meter 8 is input to a power supply frequency control circuit 9, and by adjusting the power supply frequency of the high voltage power supply 10 with this power supply frequency control circuit 9, the ozone concentration generated by the ozonizer 3 is reduced to 2 ppm or less during the daytime, for example. and at night, it is controlled at 10 ppm.

約98%が死滅していた。According to the above configuration, the circulating air in the clean room 1° is sent to the ozonizer 3 by the circulation fan 2,
The discharge part of this ozonizer 3, that is, the cathode electrode 21
and the anode electrode 22, and during the day, the flow path switching valve 4. It returns to the clean room 1 via the deodorizing catalyst filling tank 5 and the filter 6, and at night the flow path switching valve 4. It returns to the clean room 1 via the bypass passage 7 and the filter 6. At this time, bacteria and mold in the circulating air are removed by ozonizer 3.
The high-voltage electric field strength (for example, 24 KV, 60 Hz) within the air kills or causes the bacteria to enter a state of suspended animation, thereby increasing the sterilization effect of the circulating air. Additionally, yeast was used to circulate the air (30m3) in clean room 1 20 times/11r.
As a result of an experiment with a frequency of pulse application of 6.1 seconds, as shown in FIG. 3, approximately 98% of the initial yeast concentration was killed after one hour.

That is, since ozone has a short reaction time compared to odor components while passing through the duct, odor remains, and this remaining odor component is vented through the deodorizing catalyst filling tank 5 together with unreacted ozone.
ここで、オゾンは酸化反応のイニシエー・夕となり、主

(2) Oxidation (deodorization) of malodorous substances by activated catalyst M' ten malodorous substances → oxide of malodorous substances + catalyst (M) In other words, the deodorizing catalyst (M) first reacts rapidly with ozone (O3) It becomes active state (M'). M' has a higher oxidation rate than ozone, easily oxidizes and deodorizes malodorous substances, and returns itself to its original state (CM). Therefore,
The general reaction is as follows: 03 + malodorous substance - oxide of malodorous substance + 02 This allows the deodorizing effect of the deodorizing catalyst to continue for a long time, and prevents the circulating air containing ozone from flowing into the clean room 1. There is.

A deodorizing catalyst (using a ternary post-synthesized oxide consisting of silicon and zirconium as a deodorizing catalyst) breaks through at about 50 H, whereas a deodorizing catalyst containing 2 ppm of ozone breaks down at about 10 H.
It has a deodorizing effect up to about 00 hours. Note that when activated carbon is used as a deodorizing catalyst, its effect is small even if it contains ozone.

率が1時間で0.01%まで低下した。In addition, in this embodiment, circulating air containing ozone is circulated through the flow path switching valve 4 at night. Since the ozone is returned to the clean room 1 through the bypass flow path 7 and the air filter, bacteria and molds adhering to the inner walls and internal equipment of the clean room 1 can be sterilized by ozone. In other words, when circulating air containing ozone flows into the clean room 1, ozone is adsorbed to the cell walls of bacteria, mold, etc. attached to the inner walls of the clean room 1 and internal equipment, and is taken into the cells. The sterilization effect in the clean room 1 can be enhanced because the metabolic mechanisms necessary for maintaining cell life, such as protein synthesis nucleotide or nucleic acid synthesis, cell wall synthesis, and cell membrane function power source metabolism, are destroyed. In addition, in order to confirm the sterilization effect in clean room 1, a spore suspension (3 1.5 to 5.8 XIO/1
) was placed in the center under the floor of clean room 1, and circulated air containing 10 ppm of ozone was pumped in at 1455 ml/
As a result of an experiment on the change in the number of viable spores over time by flowing the spores into the clean room 1 at a flow rate of sin, the survival rate decreased to 0.01% in 1 hour, as shown in FIG.

The air is returned to the clean room 1 through the deodorizing catalyst filling tank 5 and the filter 6, and at night the circulating air that has passed through the ozonizer 3 is passed through the flow path switching valve 4. By returning the air to the clean room 1 via the bypass channel 7 and the filter 6, the sterilization effect in the clean room 1 and the circulating air itself can be enhanced, and the deodorizing effect of the deodorizing catalyst can be sustained for a long time.

更が可能であることは説明するまでもない。For example, in the above embodiments, a ternary post-composite compound of titanium, silicon, and zirconium was used as the deodorizing catalyst, but activated carbon or the like may also be used. In addition, in the above embodiment, the circulating air that has passed through the ozonizer 3 is transferred to the flow path switching valve 4 at night.
.. Although the flow is returned to the clean room 1 through the bypass flow path 7 and the filter 6, the flow path switching valve 4. It may also be returned to the clean room 1 via the bypass channel 7. Furthermore, it goes without saying that various design changes can be made without departing from the gist of the present invention.
