1 is a schematic perspective view illustrating a schematic structure of a plasma shower gate system 100 of the present invention and a space in which plasma shower emission is made.

Plasma sterilization module 430 is placed on the ceiling corresponding to the upper part of the gate, and the ventilation pipe 10 is formed so that the plasma shower is made toward the inside of the gate from the ceiling and sidewall surfaces. Plasma generated by the plasma sterilization module 430 above the gate is emitted along the ceiling side blowing pipe and the side wall side blowing pipe. Plasma showers from the ceiling and sidewalls are applied to objects (including people, animals, and objects) passing through or staying in the gate. Plasma contains charged particles and active species, which are forced out through a blower pipe by a fan. The strong sterilization and virus removal of active species, decomposition of harmful substances occur, and the wind shakes off foreign substances such as fine dust attached to the object, and is aggregated by charged particles to remove it by gravity. Considering that the lifespan of the active species is about 18 to 20 seconds, even after the object hit by the plasma shower at the gate passes through the gate, the processing action by the active species is still performed for that time, and the object is moved in the space where the object moves. Actions of active species may occur in the vicinity.

2 is a schematic perspective view of a plasma sterilization module box including a plasma generating unit and an ozone removing means.

The plasma sterilization module 430 box includes a plasma room 221 having a fan 210 and a plasma generator 220 and an ozone decomposition room 231 for removing ozone generated by plasma. The fan 210 sucks air toward the plasma generator 220 , and the plasma generator 220 includes a dielectric barrier discharge plasma source. The upper end of the plasma room 221 is covered with a mesh-type cover capable of filtering foreign substances. In order to quickly remove ozone harmful to the human body, the air including plasma proceeds to the ozone decomposition room 231 by driving the fan 210 . At least one photocatalyst 230 and an ultraviolet lamp 240 are disposed in the ozone decomposition room 231, and preferably, they are alternately arranged with each other. A ballast 250 for an ultraviolet lamp is also provided. Accordingly, the photocatalyst and UV rays create synergy to quickly decompose ozone below the standard value. The air flow proceeds from the intake unit 200 to the exhaust unit 300 along the red arrow. In this way, the plasma emitted toward the exhaust unit 300 of the plasma sterilization module 430 box is emitted along the ventilation pipe placed on the gate ceiling and sidewall. The exhaust unit 300 is disposed from the gate ceiling toward the center, and a suction fan 211 is disposed at the center to emit plasma as shown in FIG. 3 to form a plasma shower.

3 shows that plasma constitutes upper air conditioning and lower air conditioning by the cross fans 30 in the plasma shower gate system, and FIG. 4 shows gas flow and sidewall gas outlets in the upper part of the plasma shower gate system.

The cross fan 30 is installed in an almost uniform distribution on the gate ceiling surface and the side wall surface to blow the wind almost uniformly and widely. Accordingly, it provides abundant wind to shake off fine dust or foreign substances adhering to objects inside the gate. In the center of the gate ceiling side, that is, the plasma sterilization module 430 box, there are a suction fan 211 and two cross fans 30 arranged toward both ends from the suction fan. Adjacent to the exhaust unit 300 of the plasma sterilization module box, there is a suction fan 211 in the center of the gate ceiling, and the exhaust port side of the suction fan 211 is connected to the upper duct 400, and left and right from the center to the upper duct 400 A cross fan 30 arranged in a row is installed. As a result, plasma is emitted downward from the gate ceiling to form a plasma shower. A sidewall duct 410 is also installed on the gate sidewall and crosspans 30 are arranged therein. In this embodiment, the crosspans 30 are arranged in pairs one by one, that is, in two rows along the length of the side wall. The number of crosspans can be adjusted as needed. Each duct has an opening facing into the gate so that the plasma shower is emitted by the crossfans seated inside the top duct and sidewall duct.

5 is a perspective view showing the appearance of the plasma shower gate system of the present invention. The display window 500 may be provided on the front/rear side of the gate, and the operation panel 600 may be installed on the front/rear side of the gate wall. An advertisement or guidance information may be displayed on the display window. The operation panel 600 may include a power switch and a blow control button. In addition, a camera, a face recognition device, and/or a thermometer may be installed to record a person's access record and body temperature.

The plasma shower emitted from the gate can be operated continuously even when there is no one passing through the gate to prevent the entire area, or it can be operated by turning on the switch before a person passes and operating it for a predetermined time and turning it off. The switch on/off may be detected by a sensor that recognizes a person and may be turned off after automatically operating for a predetermined time.

6 is a perspective view showing a blowing direction of the plasma shower gate system of the present invention. This kind of blowing allows the object to receive enough plasma shower, and by moving the object (including people, animals, and objects) through the gate, the space around the gate can be sterilized and virus removed to some extent by active species. . That is, the active species remain on the surface of the object by the plasma shower and continue the action of the active species around the object until the end of its lifespan, thereby causing actions such as sterilization and virus removal around the object.

7 to 9 show that ozone generated when plasma is generated by applying a heater to the plasma sterilization module is removed. Ozone is easily decomposed by heat and decomposed into oxygen molecules and electrically ground state oxygen atoms (O(3P)), and O(3P) improves oxidation power. The high-temperature heater is composed of porous or mesh, allowing plasma to pass through, and surrounding the outside with the low-temperature heater. In the above, the high-temperature heater may be configured by arranging a plurality of plates having a plurality of holes at intervals.

The cooling device includes a dual structure of a primary cooling plate and a secondary cooling plate enclosing the primary cooling plate with an air gap. The inside of the low-temperature heater (the side through which the plasma passes) is coated with an oxide film. The plasma generating unit is connected to the porous plasma suction tube, and the generated plasma flows into the porous plasma suction tube, and the plasma suction tube is connected to a heater and ozone is primarily removed by heat in an ozone decomposition room ( 231) is entered. By installing a humidifier module around the plasma suction tube and supplying moisture into the plasma suction tube, activated water can be produced by plasma and active species to be used in the plasma shower (FIG. 7). Moisture also removes ozone, and activated water strengthens sterilization, virus removal, and fine dust removal functions.

FIG. 8 shows that the plasma generator is composed of a metal electrode having a pointed end and a dielectric that covers the metal electrode as it is, and is disposed near the surface of the cooling water. This configuration directly creates a mass of active water by plasma generation from the coolant at the end of the electrode module. The part that discharges the active water mass from the plasma generating unit is composed of a nozzle to form the active water droplet. The configuration of ozone removal by the heater is shown in FIG. 7 . Droplet activated water has higher sterilization and virus removal power.

9 is a double nozzle structure to reduce the particle size of the splash active water and to strengthen the spraying force. In addition to the nozzle in which the plasma generated by the plasma generator of FIG. 8 is emitted, the diameter of the nozzle is gradually reduced, and the tapered secondary nozzle is connected to the primary nozzle to make droplets smaller. The rest of the heater side configuration is the same as in FIG. 7 .

The decomposition of ozone can be made in various combinations, such as a photocatalyst and ultraviolet rays, a heater pyrolysis, a heater and ultraviolet rays, a heater and ultraviolet rays and a TiO ₂ photocatalyst.
