法及びその装置に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air cleaning method and an air cleaning method for removing air from a room such as a clean room, a hospital, a food factory, a semiconductor factory, a hotel, and the like and eliminating the electric field.

の高いものとなっている。従って粒径の小さな微粒子は
捕集することができず、クリーン化に限度がある。However, in order to obtain cleaner air, this filter has to collect fine particles having a smaller particle size, and therefore has to reduce the mesh size. In this way, the mesh is clogged with the fine particles collected in a few months, and when the mesh is clogged, the temperature rises and the saturation point of the water rises. Therefore, the passing air contains a large amount of moisture, and dew condensation occurs at the filter location. Therefore, the filters become unusable in a few months and must be replaced with new ones, which is extremely costly. Therefore, fine particles having a small particle size cannot be collected, and there is a limit to cleanliness.

る。Next, the method of the present invention will be described. The suction force of the blower 17 causes the air inlet 4
And the air enters the first spray chamber 6. There, water pumped from the second tank 3b is sprayed by the first nozzle 5 as a microsol having a particle diameter of 50 μm or less and a uniform particle diameter. The air in the first spray chamber 6 is cooled by the adiabatic expansion by the atomization and the cooling effect by the heat of vaporization. In addition, the inside of the first spraying chamber 6 becomes supersaturated with water, and the microsol particles of water in the first spraying chamber 6 are +-
Unipolarly charged to an equal amount. Then, the monopolar charged particles such as dust and dust in the air and the monopolar charged microsol on the opposite pole are mutually attracted and combined to form a water droplet having a large particle diameter. Not all of these particles are charged, for example, as described above, when water is converted into a microsol having a particle size of 50 μm or less, or when pure water containing a surfactant is similarly converted into a microsol. However, fine particles to be filtered, such as dust, are charged to either the positive or negative pole, so that the water microsol particles are sucked by these.

て排出される。The air containing the water droplets having a large particle diameter due to the aggregation is passed through the first particle separation device chamber 7, where the fine particles are collected as described above, and the fine particles in the air are removed. Then, when the air further enters the second spray chamber 9, the pure water pumped from the first tank 3a is sprayed again from the second nozzle 8 as a microsol having a particle diameter of 50 μm or less and a uniform particle diameter. As a result, the air in the second spray chamber 9 is further cooled as described above, and becomes in a supersaturated state of water. Further, the particles of the microsol in the water are monopolarly charged to + -equivalent amounts. Therefore, particles such as dust and dust in the air that could not be removed in the first particle separation device chamber 7 are also monopolarly charged. The sol and the sol mutually suck and combine to form water droplets having a large particle size. Then, the air containing the water droplets enters the second particle separation device chamber 10 and the third particle separation device room 11, and the water droplets are dropped and separated, and only the clean air containing no fine particles is supplied to the air exhaust port 12.
And is discharged through a blower 17 and a diffusion box 18.

ーの除湿をして外部に排気するようにしてもよい。In the above embodiment, a two-layer flow type particle separator is used as a method for removing water droplets or fine particles in air. However, the present invention is not limited to this.
An appropriate particle separation device such as a particle separation device that passes air through a pile of spheres or blocks such as stones may be used. In addition, if this method is repeatedly and continuously performed in each of these particle separation devices, a humid air passes through each particle separation device, so that a water film is formed. Alternatively, water may be constantly or intermittently applied to each particle separation device to form a water film. This makes it easier for water droplets in the air to adhere, making it easier to collect fine particles. in this case,
The surface tension is controlled so that water easily forms a film. For this purpose, there are a case where a surfactant is added to water to be made into a microsol and a case where a surfactant is applied to the surface of the particle separation plate itself to control the surface tension.
In the final stage of this apparatus, air comes out in a state of supersaturated humidity. Therefore, in the terminal particle separation apparatus, dehumidification can be performed efficiently by using a separation plate or the like having a super-hydrophobic surface treatment. By forming a film of fluorine, a silicon-based compound or a copolymer thereof on the surface of the super-water-repellent material, it is difficult to form a water film on the surface of the separation plate, etc. You may make it drop a water drop, and it may make it dehumidify air and exhaust it outside.

Fine particles, such as charged dust and dust, combine with these to form water droplets having a larger particle size. The water droplets having the large particle diameter are passed through a particle separation device to be separated from air, so that it is not necessary to reduce the size of the filter network in order to remove the fine particles as in the related art. Moreover, since fine particles of any particle size are collected as large-sized fine particles, collection or removal is extremely easy and reliable. Therefore, clogging of the particle separation device does not occur. In addition, bacteria, fungi, bacteria, virus, etc. are attached to fine particles such as dust and dirt,
These can also be separated and removed by this method. Further, the water fine particles are monopolarly charged and combined with fine particles such as dust and dust charged to the opposite polarity as described above, so that they are in a non-charged state. Therefore, it is an extremely efficient method of purifying air and eliminating an electric field. When water is further sprayed, the air is cooled by the temperature drop due to adiabatic expansion and the cooling effect by the heat of vaporization in the atomized state.
Accordingly, the discharged air is cleaned and cooled at the same time.
