Hereinafter, the structure of each electrode assembly 131, 132, 133, and 134 will be described in more detail.

Each electrode assembly (130: 131, 132, 133, 134) includes an electrode mounting body (135: 135-1, 135-2, 135-3, 135-4) and an electrode plate (160: 161) of a specific structure. It may be a configuration including 161-1, 162, 163, 164).

Specifically, the electrode mounting body (135: 135-1, 135-2, 135-3, 135-4) is a disk-shaped structure formed with an outer diameter of a predetermined size, and the center portion is indented with an outer diameter of a predetermined size to form an electrode plate. It is preferable that the structure has a mounting groove 136 formed therein. At this time, the electrode plates 160 (161, 161-1, 162, 163, 164) can be stably mounted in the electrode plate mounting groove 136.

In addition, the radial flow path 140 formed in the electrode mounting body 135 is preferably a penetrating structure that penetrates and connects one side and the other side of the electrode mounting body 135 on which the electrode plate 160 is mounted. In this case, current can be effectively supplied to the sterilizing water flowing along the radial flow path 140, thereby significantly improving the production efficiency of electrolyzed gas.

The radial flow path 140 may have a structure that includes both a radial structure and a bent structure. In this case, many vortices can be formed in the flow of sterilizing water, and current can be effectively supplied to the sterilizing water, ultimately maximizing the electrolysis action.

When constructing the electrode assembly 130 with a polygonal structure when viewed in plan, it is desirable to form the storage space of the housing 110 into a structure corresponding to this.

At this time, it is preferable that an inlet/outlet passage 142 through which sterilizing water can be injected or discharged between the electrode assemblies 130 is formed at a step portion formed by stacking electrode assemblies 130 having different outer diameters.

Meanwhile, Figure 3 is a diagram conceptually explaining the electrode module of Figure 2. The positive and negative plates are maintained at a certain distance with the electrode housing in between, and electrolysis or plasma reaction occurs between the positive and negative plates. The electrode housing is formed with a radial flow path for the movement of sterilizing water. The electrolysis or plasma reaction between the positive and negative electrode plates avoids the area interfered with by the radial flow path and generates multiple plasmas on the surfaces where the positive and negative electrode plates face each other, especially the negative electrode plate. Electrode protrusions may be formed for the reaction. A plurality of combinations of the positive electrode plate, the negative electrode plate, and the electrode housing existing between them may be formed, and accordingly, electrode protrusions may be formed on the negative electrode plate. The electrode protrusions have the shape of upper and lower beams and can be formed in multiple rows at regular intervals in the radial direction without being interfered with by the radial flow path. DC or AC voltage can be applied for electrolysis or plasma reaction.

A configuration diagram showing an electrochemical reaction system including an electrode module optimization device according to an embodiment of the present invention is shown.

The control unit controls the supply amount of sterilizing water, the supply amount of liquid catalyst material, the supply amount of gas catalyst material, and the amount of power provided to the electrode module optimization device based on data detected in real time from the concentration sensor, thereby adjusting the concentration of hypochlorous acid water generated. It can be easily and stably controlled within the preset range.

The electrochemical reaction system according to this embodiment can modify various fluid materials into intended properties through a specific mechanism of action.

Specifically, the mechanism of action of the electrochemical reaction system according to this embodiment has the condition of applying electrolysis or plasma while pressurizing the sterilizing water to be reformed to a predetermined pressure. At this time, gas is generated in the process of applying electrolysis or plasma, creating an environment for generation. The next condition is to pressurize the sterilizing water to be reformed to a predetermined pressure, inject a specific gas, and then apply electrolysis or plasma. The above-mentioned specific gas is a gas for creating a plasma generation environment, and examples include hydrogen, oxygen, ozone, nitrogen, carbon dioxide, argon, organic gas, and methane gas.

At this time, when the above-mentioned sterilizing water is pressurized to a predetermined amount of pressure, the sterilizing water may become an organic material, and in some cases, it may be a fluid that is a mixture of organic and inorganic materials. In addition, the above-mentioned sterilizing water can be heated to maintain smooth fluidity depending on the viscosity, and a fluid containing organic substances or a mixture of organic and inorganic substances can be heated depending on the reaction environment.

In Figure 4, the internal structure of the insecticidal liquid container 200 is shown. Compressed air supplied through a pipe to the bottom of the insecticidal liquid container 200 reaches the vibration generator 200 located at the bottom of the insecticidal liquid container 200. The insecticidal solution container 200 is filled with the insecticidal solution injected through the insecticidal solution injection port 90, and the current water level is measured by the water level sensor 82. When the insecticidal solution is vaporized in the vibration generator 200, it passes through the aqueous insecticidal solution and is delivered to the outside of the insecticidal solution container 200 through the discharge port 92 located at the upper center of the insecticidal solution container 200.

Meanwhile, a control panel is provided to control the operation of the vibration generator 200 for vaporizing the aqueous insecticidal solution. The control panel is equipped with a connection port that connects to the outside world wirelessly or by wire. The control panel may be equipped with a notification device that measures the level of the insecticidal solution present inside the insecticidal solution container 200 using a water level sensor and notifies a shortage of the insecticidal solution or an excess of the insecticidal solution. Additionally, a setting unit that can set an operation maintenance time or an operation start time may be formed in the control panel. The water level sensor 82 is installed inside the pesticide liquid container to measure the amount of pesticide liquid. The water level sensor displays the upper and lower limits.

A Venturi pipe (not shown) may be provided in the compressed air supply pipe through which compressed air is connected to the pesticide container 200. The flow rate is increased by the Venturi pipe, negative pressure is generated, and it is possible for separate chemicals or solutions to flow into the compressed air supply pipe through the Venturi pipe.

In other words, the venturi pipe can be connected to a separately equipped tank. One or more of the fumigant, N2, CO3, and He may be additionally supplied along with the carrier gas from the tank to the venturi pipe.

As shown in Figures 4 and 5, the vibration generator 200 includes a supply pipe 210 connected to the compressed air supply pipe, a horn body 220 connected to the end of the supply pipe 210, and a horn body 220. There is an external portion 230 in which is built-in, and on the surface of the external part 230 there is an external hole formation surface on which an external hole 230A is formed, and a wing diaphragm 240 is attached to the external hole formation surface. That is, the wing diaphragm 240 is not attached to the surface where the external hole is not formed.

The horn body 220 shown in FIG. 5 has an inner tube 221 in communication with the supply pipe 210, and a certain radial space in a part of the inner tube 221 so that the inner tube 221 is located along the central axis. The horn body groove 223 includes a volume 222 formed therein. A horn body hole 224 is formed from the horn body groove 223 through the volume portion 222 so that the inside of the outer shape portion 230 and the inner tube 221 communicate with each other.

In Figure 6a, a horn body hole 224 is formed in the volume portion in a radial direction from a horn body groove 223 formed at a certain position of the inner tube through which compressed air flows, and the horn body hole 224 is formed in the external portion 230. It communicates with the reflux chamber 260 formed in the internal space of.

Meanwhile, the horn body groove may be formed in a cone shape as shown in FIG. 5C.

The horn body groove in FIG. 5B is disk-shaped, with a curved surface formed along the circumference in the radial direction, and is called a disk-shaped horn body groove 223A with a constant height. The horn body groove in FIG. 5C has a cone-shaped cross-section and a vertex. It is defined as a conical horn body groove 223B in which a curved surface is formed along the circumference in the radial direction at the end of the bus bar.

The horn body holes formed in the disk-shaped horn body groove 223A and the conical horn body groove 223B, respectively, may be formed to be perpendicular to the volume portion 222 in the radial direction as shown in FIG. 5A, and the flow in the circulation chamber It may be formed in a tangential direction with respect to the volume 222 for circulation.

Additionally, the horn body hole is related to the shape of the external portion 230 of the horn body 220. That is, if the outer part 230 without the outer hole 230A is located at a position opposite the horn body hole, the insecticidal liquid vaporized from the horn body hole is small enough not to collide with the inner surface of the outer part. Only liquid vaporization droplets can be discharged through the external hole (230A). For this purpose, it is desirable that the positions of the outer hole and the horn body hole are installed at positions spaced apart from each other in the circumferential direction rather than overlapping each other in the radial direction.

FIG. 5A shows the outside where the horn body groove 223 is formed, FIG. 5B shows the left and right spaces formed inside the horn body 220, and FIG. 5C shows the top and bottom spaces formed inside the horn body 220.

Compressed air rapidly forms a flow path along the inner tube 221 into the horn body groove 223, forming left and right spaces within the horn body in Figure 5b to prevent sudden shock to the horn body 220. do. In addition, some of the compressed air along the inner tube 221 passes through the section where the horn body groove is formed from the inner tube 221, and reaches the lower part of the volume portion 222, so that the horn body 220, In particular, it creates an impact on the lower part of the horn body.

As shown in FIG. 4, one side of the vibration generator 200 and the horn body 220 is fixed to the compressed air supply line located at the top of the sterilizing water container 200, and the other side is fixed to the bottom surface of the sterilizing water container 200. Because they must maintain a distance, they form so-called free ends, which can make them more vulnerable to vibration or shock. Accordingly, in order to reduce vibration or shock caused by compressed air, a horn body buffering portion 222B is formed, which has a shape whose width narrows downward from the horn body groove 223.

On the other hand, when the outer portion 230 formed with the outer hole 230A is located at a position opposite the horn body hole, the vaporized insecticidal liquid droplets that passed through the outer hole 230A among the insecticidal liquid vaporized from the horn body hole travel through the outer hole (230A). 230A) and can be discharged.

Meanwhile, in FIGS. 5A and 6A, a reflux chamber 260 is formed between the outer shape 230 and the volume 222. Compressed air circulates along the circulation chamber 260.

The volume portion is formed to be inclined downward so that the compressed air moving from the supply pipe 210 into the outer shape portion 230 rotates along the surface of the volume portion 222, so that the cross section of the horn body 220 is tilted downward. It becomes smaller, and the space between the horn body and the outer part may have an upper-lower-light structure.

That is, the volume of the horn body is formed to be inclined so that the cross-section becomes smaller as it goes downward, and the space of the reflux chamber 260 between the volume of the horn body and the external shape may be an upper-lower light structure or space that becomes larger toward the bottom.

As shown in FIGS. 5 and 6, two or more outer holes 230A are formed in the outer portion 230 to allow compressed air to move toward the wing diaphragm 240. The outer hole 230A has a diameter of 0.3 to 0.8 millimeters and may be arranged irregularly or regularly on the surface of the outer portion 230. An external hole is formed in the external part forming a reflux chamber space between the volume part and the external volume part.

The outer shape 230 is formed in the shape of a polygonal pillar. The outer hole 230A is opened toward one side of the wing diaphragm 240 facing one side of the outer portion 230. The wing diaphragm 240 is formed in a plate shape. One side of the wing diaphragm 240 is fixed to one side of the outer shape 230, and the other side of the wing diaphragm 240 forms a plate body with a length extending from one side of the outer shape.

As shown in Figure 6b, in order to extend the length of the wing diaphragm, the cross section of the outer shape 230 of the vibration generator is formed in a polygonal shape. That is, in the embodiment of FIG. 6B, the outer shape has a hexagonal cross-section (N=6), and one or more outer holes 230A can be formed on the N surfaces forming the side surfaces of the outer shape. That is, a space for the reflux chamber 260 is formed between the volume portion 222, and an outer hole 230A can be formed through the outer portion.

The N diaphragms 240 are fixed to one side of the N surfaces on which the external holes 230A are formed and cover the N surfaces, and the compressed air in the circulation chamber can pass through the external holes and hit the N diaphragms. One side of the diaphragm 240 may be fixed to one side of the outer shape 230, and the other side of the diaphragm 240 may form a plate body with a length extending from one side of the outer shape.

In other words, the surface of the outer shape is surrounded by several square outer surfaces, each of a certain area, and the wing diaphragm is fixed in a square shape so that one side overlaps with one side of the outer surface, and the other side of the wing diaphragm is not fixed and extends from the outer surface. It is extended and exposed to the outside of the vibration generating area. Although one side of the wing diaphragm is fixed to one side of the outer surface, there is no force that restrains the other side of the wing diaphragm. Therefore, when a certain force or pressure is applied to the wing diaphragm, the further away from the fixed side of the wing diaphragm, the more the wing diaphragm moves. It bends and restores a certain amount of displacement due to elastic force, creating vibration.

That is, the compressed air that reaches the wing diaphragm 240 through the external hole 230A collides with the wing diaphragm 240. The wing diaphragm 240 generates ultrasonic waves and shock waves by a hydrodynamic sound source, and countless bubbles are generated in the insecticidal liquid present in the insecticidal liquid container.

Additionally, the cross section of the outer shape may be circular as well as N-shaped. If the outer shape is circular, the diaphragm may be formed along the circumference. In this case, the bottom surface may be a sub-shape instead of a triangle.

The vibration generator 200 further includes a horn body 220, an external portion 230, and a piezoelectric element 250 that vibrates two or more wing vibration plates 240. The piezoelectric element 250 is located between the horn body 220 and the supply pipe 210. As the piezoelectric element 250 operates, the vibration of the wing diaphragm 240 accelerates. An impact is applied to the bubbles generated on the wing diaphragm 240, and fine vaporized gas is generated in the insecticidal liquid.

In Figure 7, just as the wing diaphragm 240 is formed on the side of the vibration generator 200, the bottom diaphragm 242 may be formed on the bottom. The bottom diaphragm 242 has the same cross-section as the cross-section of the outer shape and has the same shape as the outer shape of the vibration generator, which has N polygons (triangles in FIG. 7). If the cross-section of the external shape of the vibration generator is circular rather than polygonal, the floor vibration plate has a fan-shaped shape.

In this embodiment, each of the floor vibration plates has a triangular shape as shown in FIGS. 6B and 7A, and can be fastened to the common vertices of the N triangles by the bottom fastening portion 244. The bottom fastening portion 244 serves as a lower stopper of the inner tube 221 and simultaneously fixes the bottom vibration plate. That is, they are separated by the number of outer surfaces of the vibration generator, and are fixed by the bottom fastening portion 244 at the center of the lower surface of the vibration generator. A bottom hole 246 is formed on the lower surface like an outer hole 230A on the side of the vibration generator 200 facing the bottom diaphragm of the floor fastening part, and like the outer hole 230A and the wing diaphragm 242, a bottom hole 246 ), and atomized insecticidal liquid is generated by collision with the bottom vibration plate 242, which is not attached and fixed at a small distance apart.

Meanwhile, the triangular-shaped bottom vibration plate 242 may be formed to extend in the radial direction to be larger than the area of the bottom surface of the vibration generator.

The triangular-shaped bottom diaphragm 242 can avoid interference with the wing diaphragm 242 by forming the lower surface of the vibration generator in a downward direction, that is, at a position extending further in the longitudinal direction of the vibration generator.

In addition, as shown in Figure 7b, when dismantling the bottom fastening portion 244, contamination or purging of residues inside the vibration generator by compressed air is possible through the bottom hole 246.

In Figure 8, the sterilizing bubble water and the vaporized insecticidal solution generated from the sterilizing bubble water and the insecticidal liquid sprayer are discharged through the outlet located at the top of the sterilizing and insecticidal sprayer, respectively. The sterilization bubble water flows in along the flow path formed at the top along the rear end of the sterilization and insecticide sprayer, and with the help of compressed air supplied from a 3-way valve, it is supplied with compressed air in the form of a two-fluid nozzle for sterilization bubble water. It is sprayed through the sterilization bubble water outlet 280, and a fan 290 is installed above the sterilization bubble water outlet to control diffusion in the space when spraying.

Additionally, Figure 9 shows a structure for strengthening the reflux flow in the reflux chamber 260. Figure 9a shows the position of the horn body hole 224 from the disk-shaped horn body groove 223A formed at a certain position of the inner tube 221 to the reflux chamber 260, from the most convex part of the cross section of the disk-shaped horn body groove. A horn body hole is formed. Figure 9b shows the case of the conical horn body groove 223B, and the horn body hole is formed from the most convex part of the cross section. Figure 9cd shows that the horn body hole 224 is formed downward, which is a structure to prevent the horn body groove from being filled with fluid and no longer being discharged during operation. At this time, the starting position of the horn body hole may be located below FIG. 9AB. Figure 9e is a view of the horn body hole from above, and is positioned radially, spaced apart at a certain angle, but perpendicular to the volume. Figure 9f is a swirl type structure in which the horn body hole is formed in a curve, which can further induce swirl flow in the reflux chamber. 9EF shows that there may be a tapered type whose cross-section becomes narrower as it moves away from the horn body groove. That is, there may be at least a partial region where the cross-sectional area becomes narrower in the radial direction from the horn body groove.

The vaporized insecticidal liquid is located in front of the 2-fluid nozzle for sterilizing bubble water and is installed at a lower position than the 2-fluid nozzle for sterilizing bubble water, so that the insecticidal liquid outlet 270 targets a location closer to the sterilizing and insecticidal sprayer. The insecticidal liquid is sprayed through.

It can be mounted on a portable smart device in the form of a program to operate the sterilization and insecticide sprayer in the field.
