Description

Technical Field

[0001] The utility model relates to the technical field of water vapor reflux devices, in particular to a water vapor reflux device for a cooling tower. Background Art

[0002] A cooling tower is a heat exchange device used to cool hot water or other liquids by contacting them with air and evaporating them. It is mainly used in industrial and commercial fields to cool hot water circulation systems, coolants, chemical process fluids, etc. The main advantages of cooling towers include efficient heat transfer, energy saving and environmental protection. Through the cooling tower, hot water or liquids can fully contact with the air and evaporate to achieve a cooling effect. This can avoid or reduce the need to use coolants, reduce energy consumption, and reduce the impact on the environment.

[0003] During the operation of the cooling tower, hot water is sprayed and cooled by the packing layer, and part of the water evaporates to form steam. This steam contains high energy. If it is not effectively controlled, it will escape from the top of the cooling tower, causing energy loss. At the same time, the uncollected steam also contains pollutants and waste heat generated in the industrial process. If it is directly discharged, it may pollute the atmosphere and water resources. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a water vapor reflux device for a cooling tower, aiming to improve the problem that some cooling towers have a single structure and cannot recycle and collect water vapor, resulting in energy waste.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water vapor reflux device for a cooling tower, comprising a tower body, a fixing ring fixedly connected to the inner wall of the tower body, an extension platform provided on the inner wall of the fixing ring, a fixing assembly provided on the side wall of the extension platform, a mounting plate provided inside the tower body, the side wall of the mounting plate being slidably connected to the inside of the fixing ring, the lower surface of the mounting plate being fitted with the upper surface of the extension platform, a screw hole being penetrated through the inside of the mounting plate, a pipe being provided inside the tower body, a spiral pattern being provided on the side wall of the pipe, the spiral pattern being matched with the screw hole, and the pipe being threadedly connected to the inside of the mounting plate through the spiral pattern.

[0006] Furthermore, the fixing assembly includes a positioning seat and a fixing button, the side wall of the positioning seat is fixedly connected to the side wall of the extension platform, the side wall of the positioning seat is slidably connected to the inside of the mounting plate, and the inner wall of the fixing button is threadedly connected to the side wall of the positioning seat.

[0007] Furthermore, a positioning block is fixedly connected to the side wall of the tower body, and a positioning ring is arranged on the top of the tower body.

[0008] Furthermore, a groove is provided inside the positioning ring, and the groove is engaged with the positioning block.

[0009] Furthermore, the side wall of the positioning ring is fixedly connected with a reinforcement beam, a connection cover is fixedly connected between the reinforcement beams, and the inner wall of the connection cover is provided with a lobster clasp.

[0010] Furthermore, a chain is fixedly connected to the side wall of the tube, and one side of the chain is arranged inside the lobster clasp.

[0011] Furthermore, a connecting ring is fixedly connected to one side of the reinforcement beam.

[0012] The utility model has the following beneficial effects:

[0013] 1. In the utility model, the effect of recycling water vapor is achieved through the cooperation between the tower body, pipes, positioning rings, grooves, reinforcement beams, connecting covers and connecting rings, which solves the problem that some cooling towers have a single structure and cannot recycle and collect water vapor, causing energy waste. The above structure improves energy utilization and reduces pollution.

[0014] 2. In the utility model, the loss of water vapor is avoided and energy consumption is reduced by arranging pipes inside the tower body. At the same time, the coordination among the fixing ring, the extension platform, the positioning seat, the mounting plate, the fixing button, the screw hole and the spiral pattern is used to facilitate the replacement of the pipes. The pipes are fixed in a separate manner, and there is no need to replace all the pipes at the same time when replacing them. This solves the problem that in the water vapor reflux device of some cooling towers, the installation method of the pipes is fixed, and it is not convenient to replace the pipes when they are old and damaged, resulting in a deterioration of the water vapor reflux effect. The above structure improves the efficiency of replacing the pipes in the later stage of the equipment, and ensures the stability of the equipment during water vapor reflux work.

[0015] 3. In the utility model, the top frame is assembled by the positioning ring, the reinforcement beam and the connecting ring, and the cooperation between the positioning block and the groove reduces the difficulty of installing the top frame and improves the installation efficiency. The cooperation between the chain and the lobster buckle further achieves the effect of fixing the pipe, ensuring the stability of the pipe when it is placed. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a water vapor reflux device for a cooling tower, comprising a tower body 1, a fixing ring 2 is fixedly connected to the inner wall of the tower body 1, an extension platform 3 is arranged on the inner wall of the fixing ring 2, a fixing assembly is arranged on the side wall of the extension platform 3, a mounting plate 5 is arranged inside the tower body 1, a side wall of the mounting plate 5 is slidably connected to the inside of the fixing ring 2, a lower surface of the mounting plate 5 is fitted with an upper surface of the extension platform 3, a screw hole 7 is opened through the inside of the mounting plate 5, a pipe 8 is arranged inside the tower body 1, a spiral pattern 9 is arranged on the side wall of the pipe 8, the spiral pattern 9 is consistent with the screw hole 7, the pipe 8 is threadedly connected to the inside of the mounting plate 5 through the spiral pattern 9, the fixing assembly comprises a positioning seat 4 and a fixing button 6, a side wall of the positioning seat 4 is fixedly connected to the side wall of the extension platform 3, a side wall of the positioning seat 4 is slidably connected to the inside of the mounting plate 5, and an inner wall of the fixing button 6 is threadedly connected to the side wall of the positioning seat 4.

[0024] The water vapor floats upward under the guidance of the tower body 1. During this process, the water vapor passes through the screw hole 7 and then enters the interior of the pipe 8. The pipe 8 is made of a steam-absorbing plate material, which is a plate-like material with a porous structure. The condensing agent is evenly sprayed on its surface so that the condensate covers the entire surface area and contacts with the steam, thereby realizing heat transfer and condensation. When the water vapor contacts the inner wall of the pipe 8, due to the temperature difference and heat transfer, the water vapor gradually releases the heat it carries and slowly condenses into water. These water droplets adhere to the inner wall of the pipe 8, and finally drip slowly along the inner wall and gather at the bottom of the inner wall of the tower body 1. However, during long-term use of the equipment, when the pipe 8 becomes old and damaged and needs to be replaced, the operator only needs to select the pipe 8 to be replaced and take it out from the inside of the mounting plate 5 by twisting it. This design not only simplifies the replacement process, but also greatly reduces the maintenance cost. When installing a new pipe 8, it is also only necessary to twist the spiral pattern 9 set at the bottom of the pipe into the inside of the screw hole 7 to complete the installation, thereby achieving the effect of quick installation without the need to replace all pipes 8 at the same time.

[0025] Reference Figure 3 - Figure 4 A positioning block 10 is fixedly connected to the side wall of the tower body 1, a positioning ring 11 is arranged on the top of the tower body 1, a groove 12 is opened inside the positioning ring 11, the groove 12 is engaged with the positioning block 10, a reinforcing beam 13 is fixedly connected to the side wall of the positioning ring 11, a connecting cover 16 is fixedly connected between the reinforcing beams 13, a lobster buckle 15 is arranged on the inner wall of the connecting cover 16, a chain 14 is fixedly connected to the side wall of the pipe 8, one side of the chain 14 is arranged inside the lobster buckle 15, and a connecting ring 17 is fixedly connected to one side of the reinforcing beam 13.

[0026] The cooperation between the positioning block 10 and the positioning ring 11 can provide accurate positioning and fixation of the top structure, thereby ensuring the structural stability and working performance of the entire cooling tower. The structure of the groove 12 and the reinforcement beam 13 helps to increase the strength and rigidity of the positioning ring 11. The snap-fitting action of the groove 12 makes the connection between the positioning block 10 and the positioning ring 11 more secure and can withstand greater forces and vibrations. The setting of the reinforcement beam 13 further provides structural support and reinforcement for the tower body 1, enhancing the stability and durability of the entire cooling tower. The lobster clasp 15 can tightly lock the pipe 8 to prevent it from loosening or falling off, thereby ensuring the safety and stability of the pipeline.

[0027] Working principle: When the equipment is used, when water vapor floats upward inside the tower body 1, it will move from the inside of the screw hole 7 into the inside of the pipe 8. At this time, due to the temperature difference and heat transfer, the water vapor will release heat and gradually condense into water, and adhere to the inner wall of the pipe 8, drip downward, and collect at the bottom of the inner wall of the tower body 1. When the equipment is used for a long time and the pipe 8 is old and damaged and needs to be replaced, you can select the pipe 8 to be replaced, and then remove the chain 14 on the top from the inside of the lobster buckle 15, and then twist the pipe 8 to take it out from the inside of the mounting plate 5 for replacement. During installation, twist the spiral pattern 9 set at the bottom of the pipe 8 into the inside of the screw hole 7. After completion, install the chain 14 inside the lobster buckle 15, and fix the pipe 8 again to ensure the stability of the pipe 8 when it is placed.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
