BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a conceptual diagram showing a hydrosolization apparatus according to an embodiment of the present invention; FIG. Fig. 2 is a perspective view showing the outline of the hydro-hydration apparatus of Fig. 1;

The apparatus for hydroforming according to an embodiment of the present invention has an air inlet part 111 on one side and an air outlet part 112 on the other side. A first electrode mounting part 113 is provided between the one side and the other side, An air moving passage 110 in which a second electrode mounting portion 114 is formed;

The first electrode mounting portion 113 and the second electrode mounting portion 114 are disposed on the first and second electrode mounting portions 114 and 114 so that the bioparticles B contained in the air flowing through the air moving passages 110 are charged A first electrode 210 and a second electrode 220 which interact with each other to form an electric field in one direction;

A power supply unit electrically connected to the first electrode 210 and the second electrode 220 to provide a high voltage; And

(300) formed adjacent to one of the first electrode (210) or the second electrode (220) and storing the carrier liquid (W) for collecting the bio particle (B) in a liquid phase .

Here, the bioparticles (B) may mean microorganisms floating in the air, that is, viruses, bacteria, and the like.

Here, the air moving passage 110 may be formed such that the upper surface 115 includes a curved surface, and the lower surface 116 includes a plane, according to an embodiment. For example, the upper surface 115 of the air passage 110 may be formed in an arch shape. This shape improves the durability of the device and can smooth the flow of air.

And may include a blower provided on the air movement passage 110 to allow air to move. The blower may be, for example, a blower fan or an air pump. But is not limited thereto and includes all the devices that allow air to move to the air passage 110.

The blower may be installed at one side, the other side, or one side and the other side of the air movement passage 110, and may be installed adjacent to the air movement passage 110. However, the installation location is not limited to this.

The first electrode 210 and the second electrode 220 may be disposed opposite to each other in a direction perpendicular to the longitudinal direction of the air movement path 110. In order to achieve this, the first electrode mounting portion 113 and the second electrode mounting portion 114 may be formed on the upper portion and the lower portion of the air transfer passage 110, respectively. Specifically, the first electrode mounting portion 113 and the second electrode mounting portion 114 may be respectively formed on the upper surface 115 and the lower surface 116 of the air movement path 110, respectively.

The first electrode 210 and the second electrode 220 may interact with each other to form an electric field. If an electric field exceeding a threshold value is formed between the first electrode 210 and the second electrode 220, a corona discharge due to a high voltage is generated, and a part of the air is ionized to generate ions (I). The ion (I) is accelerated in one direction under an electric field, and collides with the bioparticles (B) in the air moving through the air transfer passage (110) to charge the bioparticles (B).

The charged bioparticles B are electrically polarized and thus accelerated in one direction by an electric field formed between the first electrode 210 and the second electrode 220. Here, one direction may mean a direction toward the carrier liquid W. That is, the charged bioparticles (B) can be captured in liquid phase in the carrier liquid (W).

The first electrode 210 may be formed to have a tip end portion and the second electrode 220 may be formed to have a plate portion according to an embodiment of the present invention. The second electrode 220 has a relatively weaker electric field than the first electrode 210.

When an electric field is generated between the first electrode 210 and the second electrode 220, a part of the air moving through the air transfer passage 110 through the corona discharge is ionized, and the ions I have a weak electric field And accelerates toward the second electrode 220 side. That is, it accelerates along the direction perpendicular to the longitudinal direction of the air movement passage 110.

On the other hand, since the second electrode 220 is wider than the first electrode 210, a larger amount of ions I are located on the second electrode 220 side than on the first electrode 210 side.

Here, the corona discharge may mean that a part of the air is ionized by an electric field. That is, when an electric field is formed, free electrons in the air accelerate. When a high voltage equal to or higher than an insulation breakdown voltage is formed between the first electrode 210 and the second electrode 220, free electrons are accelerated above a threshold value, It collides with the particles in the air and destroys the particles. The destroyed particles are again broken up by electrons and ions (I), and the phenomenon that the ions (I) are generated becomes larger like an avalanche, and this phenomenon is called a corona discharge.

In this embodiment, the process of ionizing the air through the electric field to charge the bioparticles (B), accelerating the charged bioparticles (B) through the electric field and collecting them in the carrier liquid (W) And the collecting part are not formed separately but are integrally formed in one apparatus, it is possible to downsize the apparatus for hydroforming.

The first electrode mounting portion 113 may have a first space portion 113P which is recessed upward so that the tip portion of the first electrode 210 does not protrude from the upper surface 115 of the air moving passage 110 have. The tip end portion can be seated and installed in the first space portion 113P.

This structure has the effect of preventing the air moving through the air movement passage 110 from passing through the region where the ions I are not formed.

The second electrode mounting portion 114 may have a second spatial portion 114P formed by recessing the lower surface 116 of the air moving passage 110 downwardly from the plate portion of the second electrode 220. Under such a structure, the plate portion can be seated and installed in the second space portion 114P and does not interfere with the smooth flow of air.

The water tank 300 may mean a place where the carrier liquid W for collecting the liquid phase of the bio particle B is stored. The carrier liquid W may be, for example, DI water, PBC solution or the like. The carrier liquid W can be applied to the surface of the carrier liquid W stored in the water tank 300 to face the lower portion of the first electrode 210 on which the electric field is formed and the charged bioparticles B accelerated through the electric field, The air can be exposed to the inside of the air passage 110 so as to collide with the air.

Here, the water tub 300 may be provided at an upper portion of the plate portion. That is, the water tank 300 may be disposed between the first electrode 210 and the second electrode 220, and may be located adjacent to the upper surface 301 of the second electrode 220.

Specifically, the water tank 300 can be defined as the upper surface 301 of the plate portion and the circumferential surface 302 of the second electrode mounting portion 114. That is, the bottom surface of the water tank 300 becomes the upper surface 301 of the plate portion, and the circumferential surface 302 of the water tank 300 can be the circumferential surface 302 of the second electrode fixing portion.

The plate portion may be formed with a liquid inflow portion 221 for supplying the carrier liquid W to the water tank 300 and a liquid recovery portion 222 for recovering the carrier liquid W from the water tank 300. The liquid inflow section 221 and the liquid recovery section 222 may be in the form of through holes passing through the plate section. It is not limited to this shape.

The hydrosolator 100 according to the present embodiment may include a circulation line connecting the liquid inlet and the liquid recovery section 222, respectively. A detent portion for analyzing the carrier liquid W in which the bioparticles B are collected may be connected to one side of the circulation line.

The carrier liquid W can circulate continuously through the liquid inflow section 221, the water tank 300, the liquid recovery section 222 and the detec- tion section through the circulation line, (B) Liquid capture of aerosol is possible.

3 is a flow chart illustrating a method of hydrosoleting according to another embodiment of the present invention.

Meanwhile, the hydro-solification method according to another embodiment of the present invention includes an air movement step (S100) of moving air containing bioparticles (B) through an air movement passage (110); An electric field generating step (S110) of generating an electric field between the first electrode 210 and the second electrode 220 respectively formed on the upper surface 115 and the lower surface 116 of the air movement path 110; And
