Description

Technology Field

[0001] The present invention relates to a high-pressure mist pole device for spraying water particles to reduce outdoor heat waves, and to a high-pressure mist pole device that dramatically improves the flight distance of water particles. Background Technology

[0002] Generally, conventional high-pressure mist pole devices rely solely on nozzle spray pressure, so when a backwind or crosswind blows, water particles (mist) spread out or flow backward, and the actual spray distance is limited to within 1m.

[0003] If the flight distance of water particles is short, the cooling effect is limited to a localized area around the high-pressure mist pole device, which hinders the efficiency of heat wave reduction in large outdoor spaces.

[0004] In addition, conventional high-pressure mist pole devices rely mostly on natural diffusion for the movement of water particles after spraying.

[0005] In environments where there is a headwind or a side wind, water particles may remain near the injection point or flow back.

[0006] In addition, if the forward transport force due to airflow is insufficient, an early settling phenomenon may occur where water particles fall before evaporating, or they may flow along the walls of the pole.

[0007] On the other hand, the high-pressure mist pole device can be configured by adding a fan and a motor to increase the flight distance of water particles; however, this results in fan noise issues, requires an electrical system to supply power to the motor, poses a risk of electrical accidents due to short circuits, and incurs significant maintenance costs.

[0013] In addition, the high-pressure mist pole device according to an embodiment of the present invention may further comprise an extension guide (70) connected to the ejector (60) and formed to extend the path through which the airflow passes and to suppress the diffusion of the airflow.

[0014] In addition, the extension guide (70) of the high-pressure mist pole device according to an embodiment of the present invention may be formed such that the cross-sectional area decreases as it goes toward the outlet, thereby suppressing the decrease in airflow velocity.

[0015] In addition, the extension guide (70) of the high-pressure mist pole device according to an embodiment of the present invention may be formed such that the cross-sectional area increases toward the outlet to induce airflow diffusion.

[0016] In addition, the extension guide (70) of the high-pressure mist pole device according to an embodiment of the present invention may extend from the outlet of the ejector (60) to form a straight or curved flow path.

[0017] In addition, the extension guide (70) of the high-pressure mist pole device according to an embodiment of the present invention may be configured such that its inner surface is formed smoothly to suppress the generation of turbulence in the airflow.

[0018] In addition, the ejector (60) of the high-pressure mist pole device according to an embodiment of the present invention may have a non-circular cross-sectional structure having an opening in which a portion of the lower section is open to induce the discharge of moisture or condensate.

[0019] In addition, the high-pressure mist pole device according to an embodiment of the present invention may be equipped with a plurality of ejector guides (62) arranged radially around the nozzle (40) to maintain the straightness of the airflow between the inner surface of the ejector (60) and the nozzle (40).

[0020] Specific details of other embodiments are included in the detailed description and drawings. Effects of the invention

[0021] The ejector structure of the high-pressure mist pole device according to an embodiment of the present invention has the effect of increasing the flying distance of water particles when there is no wind by 2 to 3 times (e.g., from 1 m to 3 m) under specific conditions, according to one example.

[0022] In addition, the ejector structure of the high-pressure mist pole device according to the embodiment of the present invention has the effect of maintaining or increasing the flight distance of water particles even when an external wind speed blows from the reverse or lateral direction at approximately 4 to 8 m / s.

[0027] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. The presented embodiments are examples to aid in understanding the present invention, and may be implemented with various modifications different from the presented embodiments without departing from the technical spirit or essential features of the present invention.

[0030] Meanwhile, terms such as "first," "second," etc., may be used to describe various components, but the components are not limited by such terms. These terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be named the second component, and similarly, the second component may be named the first component.

[0031] The definitions of terms used in this specification may vary depending on the context and must be determined by referring to the entire content of the specification.

[0032] Throughout the specification, the same reference numerals refer to the same components.

[0033] First, the ejector structure of a high-pressure mist pole device according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIGS. 1 to 3 are drawings for explaining the ejector structure of a high-pressure mist pole device according to an embodiment of the present invention, where FIG. 1 is a perspective view, FIG. 2 is a front view, and FIG. 3 is a cross-sectional view.

[0034] The ejector structure of a high-pressure mist pole device according to an embodiment of the present invention may be configured to include a pole (1), a louver (10), a main duct (20), a manifold (30), a nozzle (40), a sub-duct (50), and an ejector (60).

[0035] The pole (1) is a structure that is fixedly installed on the ground.

[0036] The louvers (10) are positioned at the bottom of the pole (1) and allow air to flow in from the outside. Air can be drawn into the louvers (10) from all sides of the pole (1), or, as shown in FIG. 1, air can be drawn in from the front and left and right sides.

[0037] As shown in the detailed view of FIG. 3, the louver (10) has multiple blades formed in a shape that rises from the outside to the inside, and external air is introduced through the gaps between the blades.

[0038] The main duct (20) is connected to the upper side of the louver (10) inside the pole (1) and forms an upward airflow in the air. More specifically, as the temperature rises, an upward airflow naturally forms, flowing from bottom to top. Additionally, an upward airflow can be formed by the inflow of external air. The main duct (20) serves as a passage through which the air introduced through the louver (10) passes as it rises.

[0039] Meanwhile, the above-mentioned louver (10) may be configured with various number of surfaces depending on the installation environment or the required amount of air intake. Specifically, it may be formed as a one-sided structure formed on only one side of the four sides of the pole (1), a two-sided structure formed on two sides that are adjacent or opposite to each other, or a three-sided structure that inhales air from three directions including the front and left and right sides, as exemplified in FIG. 1.

[0040] In this way, the louver (10) can be configured by changing the design according to the installation environment or the required intake volume, thereby blocking foreign substances entering from a specific direction while optimizing and securing the necessary air intake volume.

[0041] The manifold (30) is positioned parallel to the main duct (20) and supplied with water from the outside. More specifically, a fluid supply line (32) is connected to the lower part of the manifold (30), and a fluid recovery line (34) is connected to the upper part of the manifold (30). The fluid supplied to the manifold (30) is water under high pressure.

[0042] The nozzle (40) is installed on the manifold (30) and sprays water in the form of fine particles. That is, as high-pressure water passes through the nozzle (40), the water changes into fine particles and is sprayed into the atmosphere.

[0043] The sub-duct (50) branches off from the main duct (20). That is, the rising airflow formed in the main duct (20) can be moved through the sub-duct (50).

[0044] The ejector (60) is connected to the sub-duct (50) and can be positioned around the nozzle (40) in a direction parallel to the injection direction of the nozzle (40).

[0045] As shown in FIGS. 6a and 6b, the ejector (60) may have an ejector guide (62) formed therein. The ejector guide (62) contributes to maintaining the airflow in a straight line.

[0046] In addition, the interior of the ejector (60) may be equipped with a plurality of ejector guides (62) to guide the flow direction of the airflow and align the straightness.

[0047] As illustrated in FIGS. 6a, 6b, and 8, the ejector guide (62) may be configured in the form of a plurality of blades that radially connect the inner surface of the ejector (60) and the center where the nozzle (40) is positioned. In particular, the ejector (60) and the ejector guide (62) according to the present invention are characterized by having a 'C'-shaped or horseshoe-shaped cross-sectional structure in which the lower side is open for a certain portion, without completely closing the outer surface of the nozzle (40). Through this lower open structure, the following organic effects can be derived.

[0048] When water particles are sprayed at high pressure from the nozzle (40), even if some particles collide with internal components of the ejector and become droplets, they are immediately discharged in the direction of gravity through the lower opening. This fundamentally prevents water from accumulating inside the airflow passage, thereby blocking foreign substances from adsorbing or bacteria from multiplying, and maximizes the hygienic management efficiency of the device.

[0049] By opening the airflow at the bottom at the initial point where water particles are sprayed, the vortex phenomenon that may occur at the bottom of the nozzle is prevented. This prevents the water particles from flowing along the wall of the pole (1) immediately after spraying, and allows the forward thrust of the air curtain to be maintained more stably. In addition, due to the structural characteristic of having an open bottom, there is an advantage that it is easy to inspect the exposed state of the nozzle (40) or to clean and replace it through the lower space without disassembling the entire device.

[0050] The previously described upward airflow passes through the sub-duct (50) and is sprayed in the same direction as the moisture sprayed from the nozzle (40), and in particular, the sprayed air can form an air curtain.

[0051] The air curtain can protect the water particles sprayed from the nozzle (40) from being affected by external wind. That is, it reduces the influence of external wind when the water particles travel in a straight line, and consequently ensures the maximum distance of the water particles.

[0052] With reference to FIGS. 4 through 8, the main configuration of the ejector structure of a high-pressure mist pole device according to an embodiment of the present invention will be described in detail. FIGS. 4 and 5 are drawings showing the main configuration of the ejector structure of a high-pressure mist pole device according to an embodiment of the present invention, where FIG. 4 is a perspective view and FIG. 5 is a cross-sectional view. FIGS. 6a and 6b are perspective views showing portion A of FIG. 4. FIG. 7 is a cross-sectional view along line BB of FIG. 5 and a cross-sectional view along line CC of FIG. 5. FIG. 8 is a detailed view showing portion D of FIG. 5.

[0053] As shown in FIGS. 4 and 5, the main duct (20) has a large diameter portion (22) formed on the lower side and a small diameter portion (24) formed on the upper side, and the large diameter portion (22) and the small diameter portion (24) can be connected by a connecting portion (26) with a gentle curve.

[0054] In particular, the second inner diameter (D2) of the small diameter portion (24) can be formed to be smaller than the first inner diameter (D1) of the large diameter portion (22), thereby allowing the main duct (20) to expect a Venturi effect.

[0055] The Venturi effect is a physical phenomenon in which a fluid accelerates and its pressure decreases as it passes through a narrowing pipe.

[0056] An upward airflow is formed inside the main duct (20), and as the upward airflow rises, the flow velocity can increase as it moves from the large diameter section (22) to the small diameter section (24).

[0057] Accordingly, as the airflow with increased velocity is injected through the sub-duct (50) and ejector (60), it provides forward thrust to the water particles injected from the nozzle (40), and as a result, has the effect of increasing the flight distance of the water particles.

[0058] Therefore, when the rising airflow passes through the sub-duct (50) and the ejector (60), the flow velocity can be increased, and accordingly, a stronger air curtain can be formed, and furthermore, it can help increase the distance of water particles.

[0059] The air curtain not only blocks the inflow of external turbulence but also aligns the internal airflow in a straight line, thereby suppressing the diffusion of moisture particles and increasing forward concentration.

[0060] Meanwhile, the ejector structure of the high-pressure mist pole device according to an embodiment of the present invention may be provided in multiple numbers as shown in FIGS. 4 and 5. The multiple sub-ducts (50) are arranged apart in the vertical direction.

[0061] As shown in FIG. 7, the fourth inner diameter (D4) of the sub-duct (50) positioned on the upper side may be smaller than the third inner diameter (D3) of the sub-duct (50) positioned on the lower side.

[0062] That is, as shown in FIGS. 4 and FIGS. 5, for example, if multiple sub-ducts (50) are arranged, the sub-duct (50) placed at the bottom may have the largest inner diameter, and the sub-duct (50) placed at the top may have the smallest inner diameter.

[0063] Thus, when the updraft passes through each sub-duct (50), the flow velocity of the updraft formed in each sub-duct (50) can be similarly implemented.

[0064] An extension guide is described with reference to FIGS. 9 through 11. FIG. 9 is a cross-sectional view showing an example in which an extension guide is installed in an ejector in an ejector structure of a high-pressure mist pole device according to an embodiment of the present invention. FIGS. 10 and 11 are cross-sectional views showing other examples of an extension guide.

[0065] The ejector structure of the high-pressure mist pole device according to an embodiment of the present invention may further include an extension guide (70) as shown in FIG. 9.

[0066] The extension guide (70) has an inner diameter corresponding to the outlet diameter of the ejector (60) and is formed to extend a predetermined length (L) from the ejector (60) in the injection direction.

[0067] The extension guide (70) is connected to the ejector (60) to extend the path through which the airflow passes and to suppress the diffusion of the airflow so as to maintain straightness.

[0068] In a normal situation where there is no extension guide (70), the airflow weakens from the moment it leaves the ejector (60), so the range in which the air curtain effect can be expected may be limited.

[0069] On the other hand, if an extension guide (70) is installed on the ejector (60), the airflow is prevented from spreading widely and is allowed to extend straight and long, thereby increasing the range of the air curtain.

[0070] In particular, the extension guide (70) inhibits the separation of the boundary layer of the airflow and maintains the straightness of the flow, thereby delaying the collapse of the air curtain and maintaining the forward momentum of the moisture particles.

[0071] The air curtain forms a velocity gradient layer that suppresses the inflow of turbulent outside air.

[0072] On the other hand, the extension guide (70) may have a cross-sectional area that decreases toward the outlet as shown in FIG. 10 to maintain the airflow speed.

[0073] In this way, the speed of the airflow ejected from the ejector (60) can be suppressed from rapidly slowing down due to the Venturi effect, that is, by maintaining the speed of the airflow, it can contribute to increasing the distance of the water particles.

[0074] On the other hand, the extension guide (70) may have an increased cross-sectional area toward the outlet as shown in FIG. 11 to induce airflow diffusion. This has the effect of spreading moisture particles more widely.

[0075] Hereinafter, the distance and range of the water microparticles being sprayed will be explained with reference to FIGS. 12 to 16. FIGS. 12 to 16 are the results of simulating the distance and range of the water microparticles being sprayed.

[0076] Figure 12 is the result of simulating the ejector structure of a high-pressure mist pole device without a main duct, a sub-duct, and an ejector.

[0077] In the simulation, when the ambient temperature was set to 30℃ and the external wind speed was set to 0 m / s, the maximum distance was 1 m and the spray angle was 45 degrees.

[0078] Figure 13 is the result of simulating the ejector structure of a high-pressure mist pole device according to an embodiment of the present invention.

[0079] In the simulation, when the ambient temperature was set to 30℃ and the external wind speed was set to 0 m / s, the maximum distance was 2 to 3 m and the spray angle was 80 degrees.

[0080] Figure 14 is the result of simulating the ejector structure of a high-pressure mist pole device according to an embodiment of the present invention.

[0081] In the simulation, when the ambient temperature was set to 30℃ and the external wind speed was set to 4 m / s, the maximum distance was 2 to 3 m and the spray angle was 80 degrees.

[0082] Figure 15 is the result of simulating the ejector structure of a high-pressure mist pole device according to an embodiment of the present invention.

[0083] In the simulation, when the ambient temperature was set to 30℃ and the external wind speed was set to 6 m / s, the maximum distance was 2 to 3 m and the spray angle was 80 degrees.

[0084] Figure 16 is the result of simulating the ejector structure of a high-pressure mist pole device according to an embodiment of the present invention.

[0085] In the simulation, when the ambient temperature was set to 30℃ and the external wind speed was set to 8 m / s, the maximum distance was 2 to 3 m and the spray angle was 80 degrees.

[0086] In the ejector structure of the high-pressure mist pole device according to an embodiment of the present invention, compared to the subject of comparison in FIG. 12, as shown in FIG. 13 to FIG. 16, it can be seen that, according to one example, even if the external wind speed changes from 0 m / s to 8 m / s, the flying distance of water microparticles increases up to 3 m, which is up to 3 times, and the spray angle range is expanded by approximately 77% from 45 degrees to 80 degrees.

[0087] Therefore, the ejector structure of the high-pressure mist pole device according to the embodiment of the present invention can diffuse water microparticles over a wider area while being less affected by external wind even when external wind blows, and can lower the temperature over a wider area as the diffused water microparticles evaporate.

However, those skilled in the art to which the present invention pertains will understand that the present invention may be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims and should be interpreted to include the scope equivalent to the claims. Industrial applicability
