DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purification apparatus for promoting the generation and ionization of ultra-fine water droplets. More specifically, the present invention relates to an ultra-fine water droplet of 0.001 .mu. The present invention relates to a method and apparatus for catching fine dust present in the air with a superfine surface or a wet water film on the surface of a metal plate, separating the dust from the air, and presenting the purified air with ions in the room. Things. The method and apparatus of the present invention greatly contribute to indoor cleaning and human health.

2. Description of the Related Art Hitherto, it has been known to remove dust in air using a honeycomb filter. FIG. 1 shows an example of such a case.
A stack of 0 honeycomb filters is provided to collect dust adhering to each honeycomb filter, wash the dust adhering by spraying water from the front of the filter and drop it into a water tank, while the washed air is air-water. Through the separator, the air purification ends.

[0003] This air purification method is suitable for soot treatment in a climbing kiln and for removing large dust and dust, but it is difficult to remove fine dust and bacteria generated in a general room. .

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to remove not only large dust and dirt but also microscopic bacteria and to generate ions which are considered to be preferred by the human body and to include them in purified air. And

[0005]

According to the present invention, water is forcibly jetted toward a metal plate for generating permeable fine water droplets, and is transmitted through the metal plate to generate a large amount of ultra-fine water droplets and ions. Accelerate and store these ultra-fine water droplets on the outside of the metal plate for a while, then bring them into sufficient gas-liquid contact with the dirty air sent from outside, and adsorb and separate dust and bacteria into these ultra-fine water droplets. Therefore, the operation of the water injection is performed in many stages, for example, three stages.
By performing the above five steps, air which is well-cleaned and contains a large amount of ions can be obtained.

According to the present invention, basically, one or a plurality of permeable metal plates for generating fine water droplets are provided in a full air passage,
Injecting pressurized water toward each metal plate, permeating the metal plate, generating ultrafine water droplets and ions, and contacting the generated ultrafine water droplets with dirty air to purify the air The present invention relates to an air purification device characterized by the following.

The present invention is characterized in that a metal plate for generating permeable fine water droplets is provided in the entire air passage. This metal plate is provided with a large number of transmission holes in the plate surface, and has a point-shaped or linearly-pointed water-drop-breaking sharp-angled object facing upward. This metal plate may be in the form of a plate, a mesh, or any other material as long as it effectively breaks water droplets and allows air to pass through, but a honeycomb filter is preferred as a commercially available product.

The metal plate for generating permeable fine water droplets is provided horizontally or at an angle to fully fill the vertical air passage in order to allow fine water droplets to stay thereabove for a while and to improve the efficiency of air purification. You can do it.

A water injection pipe having a large number of water injection ports is provided above the permeable metal plate for generating fine water droplets so that water can be strongly sprayed over the entire surface of the metal plate. Sprays through the metal plate to generate a large amount of ultra-fine water droplets and ions, and makes the air and liquid mixed contact with the contaminated air above the metal plate to capture fine dust and bacteria in the water droplets, Can be poured into the tank.

According to the present invention, a metal plate for generating permeable fine water droplets provided at a horizontal angle and a water jet pipe having a water jet port above the metal plate are provided as a set. Is provided in one or two or more, preferably about three to five steps.

In the present invention, the air that has passed through the permeable metal plate for generating fine water droplets is sufficiently purified and contains a large amount of ions. In order to remove large water droplets existing in the air, it is preferable to sufficiently remove the water droplets by a gas-liquid separator located behind the air and send the air into a room as clean air.

Hereinafter, embodiments of the present invention will be described. FIG. 1 is an example of a conventional air purifying apparatus, FIG. 2 is a sectional explanatory view of a main part of the present invention, and FIG. 3 is an overall explanatory view of the air purifying apparatus.

In FIG. 2, reference numeral 1 denotes an air passage, and in this example, a gas-liquid contact portion is in a vertical direction. Reference numeral 2 denotes a metal plate for generating permeable fine water droplets, in which a honeycomb filter is used. Reference numeral 4 denotes a water injection pipe having a water injection port 3.
From here, pressurized water is sprayed onto the metal plate.

In FIG. 3, dirty air sucked by a fan from the chamber enters the air passage 1 in the vertical direction of arrow A, passes through the rectifying plate 5, and is a honeycomb which is a metal plate for generating transparent fine water droplets. It flows into the upper part of the filter 2. On the other hand, the water pressurized by the pump is injected from the water injection port 3 through the water injection pipe A, collides with the honeycomb filter 2, and when passing through the honeycomb filter 2, the generated ultrafine water droplets 6 form the air and the air. Contact with liquid, dust and bacteria in it adsorb.

In this example, a combination of a four-stage honeycomb filter and water injection is shown, the air is purified, and the air containing ions is sent in the direction of arrow B, and is contaminated by dust and the like. The water drops fall into the tank 7. The air flowing in the direction B is sent to the cyclone 8, where larger water droplets are separated and sent into the room as clean air.

[0016]

According to the present invention, by providing a vertically permeable metal plate for generating fine water droplets in a vertical air passage, air and ultrafine water droplets can be brought into sufficient gas-liquid contact inside the metal plate. , Dust and bacteria can be effectively removed.
