に、人体生理上好ましくない影響を与え作業員の健康障
害を引き起こすおそれが大きかった。However, recently, the number of automobiles has increased, and cars are constantly congested near toll gates on toll roads, and the quality of air around the booth is extremely poor. . That is, the concentration of harmful gas components such as sulfur oxides discharged from the vehicle (SO X) and nitrogen oxides (NO X) and carbon oxides (CO X) is very high,
In addition, dust from tires and roads is mixed in at a high concentration. For this reason, if the air conditioning inside the booth is performed only by circulating the indoor air as in the past and the air components are not adjusted, the human physiology will not be affected if the workers working inside the toll collection booth work continuously for a long time. There was a great possibility that it would have an unfavorable effect and cause health problems for workers.

Although the elimination technology has been matured to some extent, there is no established technology for CO X measures, and as mentioned above, a means for efficiently removing harmful components in the air in order to prevent human health damage due to air pollution. Is desired.
【０００５】ＳＯX、ＮＯXおよびＣＯXの除去を有料道

ために採用を考慮できる手段としては次のような方法が
ある。There are the following methods which can be considered for adoption in order to solve the removal of SO X , NO X and CO X at a local place such as a toll road collection booth.
【０００６】１、気相処理技術 （１−１）気体有害成分分離膜を使用する方法 （１−２）有害成分を吸収分離する方法 ２、液相処理技術 （２−１）液中で気泡化させ液に吸収させる方法 （２−２）散水による有害成分ガスを吸収させる方法。1. Gas phase treatment technology (1-1) Method of using gas harmful component separation membrane (1-2) Method of absorbing and separating harmful components 2. Liquid phase treatment technology (2-1) Bubbles in liquid (2-2) Method of absorbing harmful gas by sprinkling water.

い。Of these methods, (1-1) is a reliable method because it requires a molecular sieve as a gas component separation membrane, but it is expensive. If the gas phase absorption and separation of (1-2) is performed, the economic difficulty can be solved, but the treatment efficiency is poor.
Although the mother liquor (tap water) absorption method (2-1) by forming fine bubbles in the liquid is a practically useful method, it has a problem of re-release of absorbed harmful components. On the other hand, according to (2-2) the absorption method using sprinkled liquid droplets (tap water), since the absorbed amount is small relative to the sprinkled amount, there is no concern about re-release into the atmosphere after treatment.

全体に微細水滴粒子として拡散し落下する。City water (tap water) is received from the city water pipe 1 into the water receiving tank 2 (arrow A). The tap water stored in the water receiving tank 2 is pressure-fed by the water feed pump 4 to the aspirator (purification chamber 15) through the water supply pipe 3 as shown by an arrow B. The tap water pumped into the purification chamber 15 is diffused and sprayed from the upper part to the lower part by the nozzle 5 in an arc shape or an inverse arc shape, and becomes sprayed water 6 that is diffused as fine water droplet particles into the entire purification chamber 15 and falls.

It may be introduced into the purification chamber 15.

される。On the other hand, the contaminated air in the toll collection booth of the room to be air-conditioned, for example, a toll road, is blown by the blower 7 through the contaminated air inlet pipe 8 to the vicinity of the upper nozzle 5 in the purification chamber 15 as indicated by arrow C. It The contaminated air, when also NO X and CO X by contains contaminants and harmful microorganisms, such as harmful gas components and soot other dust, such as SO X is an exhaust gas component of a motor vehicle. Such pollutants and the like are absorbed on the side of the water droplets to purify the contaminated air when the contaminated air sufficiently contacts the spray water 6 in the purifying chamber 15. The air from which pollutants and the like have been removed is introduced into the charge collection booth as shown by arrow D through the clean air outlet pipe 9 in the lower part of the purification chamber and blown out as clean air.

よく行われる。The blower 7 for introducing the polluted air into the purification chamber 15 under pressure may be omitted, and the polluted air may be naturally sucked by the negative pressure generated in the chamber 15. That is, the upper space portion of the spray water 6 sprayed from the nozzle 5 in the aspirator (cleaning chamber 15) is in a negative pressure state due to the flow velocity effect of the spray water, and therefore the contaminated air is pressure-fed into the aspirator using a blower. This is because the negative pressure generated in the aspirator sucks the gas even if it is not used. If a blower is used, the introduction of polluted air can be reliably and efficiently performed.

減少させることが望ましい。Here, in order to enhance the action of absorbing the pollutants by the contact between the spray water 6 and the polluted air, it is preferable that the water droplet particles of the spray water are fine particles. However, as the water droplet particles become finer, the water droplet particles are carried out from the purification chamber 15 together with the clean air (carrier out phenomenon) and blown out into the toll collection booth to increase the humidity in the booth. In order to prevent such a rise in humidity in the booth due to carrier-out, it is desirable to provide a demister (not shown) on the inlet side of the clean air outlet pipe 9 to reduce the amount of carrier-out.

る。A polluted gas separation promoting means may be added to the polluted air purifying apparatus having the above structure. As the polluted gas separation promoting means, for example, a calcium hydroxide droplet under-mixing device (not shown) attached to the water receiving tank 2 is used, and calcium hydroxide (Ca) is added to the water in the water receiving tank.
A small amount of (OH) 2 ) solution is mixed in. As a result, the sprayed water sprinkled in the purification chamber 15 becomes a calcium hydroxide solution, and this sprayed water absorbs harmful gas components in the contaminated air introduced from the booth to form calcium salts and precipitates. The separation and absorption of is promoted.

In this embodiment, a zeolite pellet tank 11 for dehumidification is provided above the aspirator, and a quick lime pellet tank 12 for removing carbon oxide is provided below the zeolite pellet tank 11. The contaminated air inlet pipe 8 opens on the upstream side of the zeolite pellet tank 11. Below the quicklime pellet tank 12, a distributor 13 is provided for uniformizing the air flow in the purification chamber that constitutes the aspirator. 14 is a partition net.

Is sent by pressure from the top of the aspirator, passes through the zeolite pellet layer 11 and the quicklime pellet layer 12, is uniformly dispersed by the distributor 13, and flows in the purification chamber from top to bottom. Here, the contaminated air passes through the zeolite pellet layer 11 to absorb and remove water. By passing this dry air through the quicklime pellet layer 12, CO x is removed. In this case, quick lime pellets have a rapidly reduced CO X absorption function due to moisture in the air, so it is desirable to provide a dehumidifying zeolite pellet layer 11 on the upstream side of the quick lime pellet layer 12.
