Description

Technical Field

[0001] This utility model relates to the field of cooling tower demisting and water collection technology, specifically to an industrial cooling tower demisting and water collection structure. Background Technology

[0002] Industrial circulating water cooling towers are important cooling devices in my country's industrial production, playing a vital role in stabilizing production processes. Water, as a heat transfer medium, is used in circulation to remove excess heat from production. The water carrying back heat is cooled in the cooling tower. Evaporation heat exchange is dominant in the cooling process. While evaporation removes heat, it also removes a lot of water. Another problem is that during winter operation, the condensed plumes (mist) formed when the hot and humid air after evaporation meets the cold air settle on the production equipment and roads around the cooling tower, causing icing and visual obstruction, which seriously affects production and road safety.

[0003] In existing technologies, a shroud is typically installed on the inner wall of the cooling tower body. The shroud has a condensation chamber at the bottom and a placement chamber and a gas collection shroud at the top. The gas collection shroud contains conical needles, and the placement chamber contains a water-catching chamber with a steam passage at the bottom. By placing the water-catching chamber into the placement chamber and inserting the conical needles into it, water in the steam can be quickly recovered, reducing water loss within the cooling tower and enabling rapid water recycling. However, in practical use, since the evaporation process occurs inside the cooling tower, adding any device reduces the ventilation area and creates wind resistance. This technology, by installing the gas collection shroud on the inner wall of the tower, results in a high wind resistance coefficient. Water collection relies on the conical needles within the shroud colliding with the mist, a passive collision method with poor water collection efficiency. Furthermore, the application of condensation technology in cooling towers, due to the high power of the tower's fans and the large evaporation air volume, results in a relatively low recovery rate. Additionally, opening air inlets in the upper part of the tower and adding condensation equipment creates significant wind resistance, affecting airflow and degrading the cooling effect of the cooling tower. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an industrial cooling tower demisting and water collection structure. Through the cooperation of the cooling tower components and the demisting and water collection components, active collision demisting and water collection are achieved during use. In different weather conditions, the demisting mounting frame can be raised and lowered according to the wind speed of the evaporated water mist to ensure the air volume and demisting and recovery efficiency of the cooling tower. It also facilitates the maintenance of equipment inside the cooling duct. The modular design of the demisting mounting frame facilitates assembly.

[0005] To solve the above-mentioned technical problems, according to one aspect of this utility model, the present utility model provides the following technical solution: an industrial cooling tower demisting and water collection structure, comprising:

[0006] A cooling tower assembly, comprising a cooling tower, a fan duct at the top of the cooling tower, a speed reducer on the top surface of the fan duct, and cooling tower fan blades connected to the speed reducer;

[0007] The demisting and water collection assembly includes a slide rail fixed to the top surface of the cooling tower, a slider fitted with the slide rail, an electric telescopic rod disposed on the top surface of the slider, a platform mounting frame connected to the top surface of the electric telescopic rod, a demisting mounting frame fitted with the platform mounting frame, an annular water collection trough disposed on the top surface of the demisting mounting frame, an airfoil blade disposed at the center of the annular water collection trough, and a shaft hole disposed at the center of the airfoil blade.

[0008] As a preferred embodiment of the industrial cooling tower demisting and water collection structure described in this utility model, the input end of the reducer is connected to a drive motor, and the drive motor controls the rotation of the cooling tower fan blades through the reducer.

[0009] As a preferred embodiment of the industrial cooling tower demisting and water collection structure described in this utility model, the demisting and water collection component further includes a rotary motor, the output end of which is connected to the shaft hole.

[0010] As a preferred embodiment of the industrial cooling tower demisting and water collection structure described in this utility model, the demisting installation frame is provided in a plurality of units, and the plurality of demisting installation frames are arranged at equal intervals within the platform mounting frame.

[0011] Each defogging mounting frame is equipped with a corresponding annular water collection tank, airfoil blades, and shaft holes.

[0012] As a preferred embodiment of the industrial cooling tower demisting and water collection structure described in this utility model, it further includes a combined limiting component, which includes a rectangular slot opened at the edge of the demisting mounting frame, a spring disposed in the rectangular slot, and a protrusion connected to the spring.

[0013] As a preferred embodiment of the industrial cooling tower demisting and water collection structure described in this utility model, the combined limiting component further includes a notch groove formed inside the platform mounting frame.

[0014] The notch and the protrusion engage with each other.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] By cooperating with the cooling tower components and the demisting and water collection components, active collision demisting and water collection are achieved during use. In different weather conditions, the demisting installation frame can be raised and lowered according to the wind speed of the evaporating water mist to ensure the air volume of the cooling tower and the demisting and recovery efficiency. It also facilitates the maintenance of equipment inside the cooling duct. The modular design of the demisting installation frame makes assembly convenient.

[0017] The combination of limiting components allows for easy automatic locking of the defogger mounting frame, preventing loosening and wobbling that can occur with its modular design. The locking mechanism eliminates the need for multiple bolt points, making it convenient to use.

[0018] In practical use, the output end of the rotary motor is connected to the shaft hole, which drives the airfoil blades to rotate. The airfoil blades demistate and recover water from the cooling tower. Through rotation, the airfoil blades rapidly collide with the fine water droplets in the evaporating mist. The resulting droplets, under centrifugal force, converge into an annular water collection tank. The collected water is then centrally collected in a storage tank via a guide pipe. Because the collected water is close to distilled water, it can be used as pre-treatment feedwater for boiler water membrane treatment, reducing the membrane load. This physical method of recovering evaporating water from cooling towers is simple, effective, energy-efficient, and easy to maintain, making it a promising investment. Return on investment; the airfoil blades are designed with angled obstruction blades, which utilize the airfoil angle to ensure demisting while increasing suction force and reducing the wind resistance coefficient generated by the device. Protrusions or depressions are added to the windward surface of the airfoil blades to increase the contact area with the mist, and the surface of the airfoil blades is treated with hydrophilicity. The slider slides in the slide rail, and the electric telescopic column drives the platform mounting frame to rise and fall, thereby controlling the height of the demisting mounting frame. The platform can be raised to ensure the cooling airflow when the wind speed is high, and the platform can be lowered to prevent water mist from overflowing from the air duct when the wind speed is low in winter.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] This utility model provides an industrial cooling tower demisting and water collection structure. Through the cooperation of the cooling tower components and the demisting and water collection components, active collision demisting and water collection are achieved during use. In different weather conditions, the demisting mounting frame can be raised and lowered according to the wind speed of the evaporated water mist to ensure the air volume and demisting and recovery efficiency of the cooling tower. It also facilitates the maintenance of equipment inside the cooling duct. The modular design of the demisting mounting frame facilitates assembly.

[0030] Figures 1-4 The diagram shown is an overall structural schematic of one embodiment of the demisting and water collection structure of an industrial cooling tower according to this utility model. Please refer to [link / reference]. Figure 1-4 The main structure of this embodiment includes a cooling tower assembly and a demisting and water collection assembly.

[0031] The cooling tower assembly is used in conjunction with the demisting and water collection assembly. Specifically, the cooling tower assembly includes a cooling tower 11, a wind duct 12 located at the top of the cooling tower 11, a speed reducer 14 located on the top surface of the wind duct 12, and cooling tower fan blades 13 connected to the speed reducer 14.

[0032] In practical use, the demisting and water collection component is installed and used based on the cooling tower 11 and the air duct 12.

[0033] The demisting and water collection assembly is used to achieve efficient demisting and water collection. Specifically, the demisting and water collection assembly includes a slide rail 21 fixed to the top surface of the cooling tower 11, a slider 22 fitted with the slide rail 21, an electric telescopic column 23 set on the top surface of the slider 22, a platform mounting frame 24 connected to the top surface of the electric telescopic column 23, a demisting mounting frame 25 fitted with the platform mounting frame 24, an annular water collection trough 26 set on the top surface of the demisting mounting frame 25, an airfoil blade 27 set at the center of the annular water collection trough 26, and a shaft hole 28 set at the center of the airfoil blade 27.

[0034] In practical use, the output end of the rotary motor is connected to the shaft hole 28, which drives the airfoil 27 to rotate. The airfoil 27 is used to demist and recover water on the cooling tower 11. Due to its rotation, the airfoil 27 quickly collides with the fine water droplets in the evaporating mist. The water droplets formed by the collision converge into the annular water collection tank 26 under the action of centrifugal force. The collected water is then concentrated and recycled into a storage tank through the guide pipe 261. Because the collected water is close to distilled water, it can be used as pre-treatment feedwater for boiler water membrane treatment, reducing the membrane load. This physical method of recovering evaporating water from the cooling tower is simple, effective, energy-efficient, easy to maintain, and has a good return on investment. The airfoil 27 is designed with a certain angle of obstruction. The airfoil angle of the blade ensures defogging while increasing suction force and reducing the wind resistance coefficient generated by the device. Protrusions or depressions are added to the windward surface of the airfoil 27 to increase the contact area with the mist. The surface of the airfoil 27 is hydrophilic. The slider 22 slides in the slide rail 21, and the electric telescopic rod 23 drives the platform mounting frame 24 to move up and down, thereby controlling the height of the defogging mounting frame 25. The platform can be raised to ensure the cooling airflow when the wind speed is high, and the platform can be lowered to prevent water mist from overflowing from the wind duct 12 when the wind speed is low in winter.

[0035] Furthermore, the combination of limiting components facilitates automatic locking of the defogger mounting frame 25, preventing loosening and shaking due to the modular structure of the defogger mounting frame 25. The locking structure design eliminates the need for multi-point bolt tightening, making it convenient to use.

[0036] Specifically, the combined limiting component includes a rectangular slot 32 opened at the edge of the defogger mounting frame 25, a spring 33 disposed in the rectangular slot 32, and a protrusion 31 connected to the spring 33;

[0037] The combined limiting component also includes a notch 34 formed inside the platform mounting bracket 24; wherein the notch 34 engages with the protrusion 31.

[0038] In actual use, the protrusion 31 and the corresponding notch 34 fit together, and the spring 33 pushes the protrusion 31 to expand outward, so that the protrusion 31 and the notch 34 are pressed together, thereby limiting the defogging mounting frame 25.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
