Description

Technical Field

[0001] This utility model relates to the field of cooling water tower technology, and more specifically, to an energy-saving cooling water tower based on circulating water. Background Technology

[0002] Natural gas undergoes significant heat release processes during extraction, processing, liquefaction (LNG), transportation, and power generation. Cooling systems are necessary to maintain process safety and efficiency. Cooling towers achieve the final dissipation of process heat through the principle of water-air heat exchange.

[0003] In the prior art, patent CN216712026U discloses a natural gas dehydration device, including a tower body. A natural gas inlet pipe is located at the lower end of the tower body. A cooling mechanism is located in the lower part of the tower body. The cooling mechanism includes two partitions and multiple cooling pipes connected to the two partitions. The periphery of the two partitions is connected to the tower body. Several vent holes are opened on the partitions. Water collection mechanisms are connected to the upper ends of the cooling pipes. A cooling water inlet pipe is connected to the upper water collection mechanism. The outer end of the cooling water inlet pipe passes through the tower body and is connected to a cooling water tank. A cooling water outlet pipe is connected to the lower water collection mechanism. A heating mechanism is connected to the upper part of the tower body, and a natural gas outlet pipe is connected to the upper part of the tower body. This device has a simple structure, is easy to transport, and is suitable for small-scale natural gas dehydration operations. Moreover, through sufficient heat exchange between the natural gas and cooling water, the natural gas can be rapidly cooled, causing the water in the natural gas to condense and fall to the bottom of the tower, thus improving dehydration efficiency.

[0004] However, the existing technology still has the following technical problems in use: the device adopts a single-stage cooling method, which makes the contact time between natural gas or other gases to be cooled and the cooling pipe extremely limited, and the contact area is also difficult to fully expand, resulting in poor cooling effect. Utility Model Content

[0005] The main objective of this invention is to provide an energy-saving cooling water tower based on circulating water, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An energy-saving cooling tower based on circulating water includes a tower body, which is fixedly installed in a frame. A circulation mechanism is provided on the tower body, comprising a water tank and a circulating water pump. A cooling device is installed in the water tank.

A second spray mechanism is provided inside the upper end of the tower body. The first and second return branch pipes are respectively connected to the first and second spray mechanisms.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figures 1-3As shown in the figure, this utility model embodiment proposes an energy-saving cooling tower based on circulating water, including a tower body 1, which is fixedly installed in a fixed frame 11. A circulation mechanism is provided on the tower body 1, which includes a water tank 12 and a circulating water pump 15. A cooling device 8 is provided in the water tank 12. One end of the circulating water pump 15 is connected to the water tank 12 through a water outlet pipe 14, and the other end is fixedly connected to a return main pipe 16. A first return branch pipe 17 and a second return branch pipe 18 are fixedly connected to the return main pipe 16. An air inlet pipe 4 is provided through the lower end of the tower body 1. A first spray mechanism 2 is provided at the air outlet end of the air inlet pipe 4. A first guide hood 6 is provided above the first spray mechanism 2. A second spray mechanism 3 is provided inside the upper end of the tower body 1. The first return branch pipe 17 and the second return branch pipe 18 are respectively connected to the first spray mechanism 2 and the second spray mechanism 3. An air outlet pipe 5 is provided at the upper end of the tower body 1.

[0020] like Figure 1 As shown, a water inlet pipe 13 is provided at one end of the water tank 12.

[0021] The circulating water pump 15 draws low-temperature cooling water from the water tank 12 through the outlet pipe 14, and then distributes the cooling water to the first return branch pipe 17 and the second return branch pipe 18 through the return main pipe 16, and then delivers it to the first spray mechanism 2 and the second spray mechanism 3 respectively. During this process, the cooling water absorbs heat and then flows back to the water tank 12, thus forming a closed loop. The inlet pipe 13 is responsible for replenishing the water tank 12 with the water lost due to evaporation, sewage discharge and other reasons, to ensure that the total amount of circulating water is constant. The cooling device 8 is a plate heat exchanger, which can further cool the circulating water in the water tank 12 to ensure that the cooling water entering the spray mechanism is always at a low temperature and improve the cooling efficiency.

[0022] like Figure 1 , Figure 3 As shown, the air inlet pipe 4 is fixedly installed on the tower body 1, and the air outlet is located inside the tower body 1.

[0023] The gas to be cooled is introduced into the tower body 1 through the inlet pipe 4, and then passes through the first spray mechanism 2 and the second spray mechanism 3 in sequence for cooling. Finally, it is sent out through the outlet pipe 5.

[0024] like Figure 1 , Figures 3-5 As shown, the first spraying mechanism 2 includes a first mounting plate 21, which is fixedly sleeved on the upper end of the air inlet pipe 4. A plurality of first nozzles 23 are arranged on the circumference of the first mounting plate 21. The first nozzles 23 are fixedly installed on the first spray pipe 22. The lower end of the first spray pipe 22 is fixedly connected to the first return branch pipe 17.

[0025] The cooling water supplied by the first return pipe 17 is sprayed out in a mist form from the first nozzle 23 through the first spray pipe 22, and comes into direct contact with the gas discharged from the air inlet pipe 4, quickly absorbing the heat carried by the gas. The first spray mechanism 2 adopts a circumferentially distributed nozzle design, which enables the cooling water to evenly cover the gas, significantly increasing the heat exchange area, effectively improving the heat exchange efficiency, and greatly enhancing the cooling effect.

[0026] like Figure 4 , Figure 5 As shown, a cross-shaped mounting bracket 24 is fixedly installed inside the upper end of the intake pipe 4, and a second air guide shroud 25 is fixedly connected to the upper end of the cross-shaped mounting bracket 24.

[0027] By installing the first guide shroud 6 at the upper end of the air intake pipe 4, the gas can be initially guided to diffuse in all directions, and the spray water can be prevented from flowing back into the air intake pipe 4.

[0028] like Figure 1 , Figure 3 As shown, the first guide shroud 6 is fixedly installed on the support frame 7, and both ends of the support frame 7 are fixedly connected to the inner wall of the tower body 1.

[0029] By setting a first guide shroud 6 above the air inlet pipe 4, the gas can be diffused in all directions, which increases the uniformity of spray cooling on the one hand, and prolongs the contact time with the spray water on the other hand, thus enhancing the cooling effect.

[0030] like Figure 1 , Figure 3 , Figure 5 As shown, the second spraying mechanism 3 includes a second mounting plate 31. Several fixing plates 32 are fixedly connected to the outer circumference of the second mounting plate 31. The fixing plates 32 are fixedly installed on the inner wall of the tower body 1. A filter plate 35 is fixedly installed in the middle of the second mounting plate 31. Several second nozzles 33 are arranged on the circumference of the second mounting plate 31. The second nozzles 33 are fixedly installed on the second spray pipe 34. The second spray pipe 34 is fixedly connected to one end of the second return branch pipe 18.

[0031] The cooling water supplied by the second return pipe 18 is sprayed out from the second nozzle 33 through the second spray pipe 34 to perform secondary cooling on the rising gas inside the tower body 1. The filter plate 35 is located in the middle of the second mounting plate 31 and can effectively filter impurities in the gas to prevent impurities from entering subsequent stages, avoid problems such as pipe blockage, and maintain smooth system operation. The second spray mechanism 3 realizes secondary cooling of the gas, further reduces the gas temperature, and significantly improves the cooling effect.

[0032] The working principle of this energy-saving cooling tower based on circulating water: During operation, the gas to be cooled enters the tower body 1 through the inlet pipe 4 and diffuses evenly in all directions under the guidance of the second guide shroud 25. In the circulation mechanism, the circulating water pump 15 draws low-temperature cooling water from the water tank 12 and splits it through the return main pipe 16. The water is then transported to the first spray mechanism 2 and the second spray mechanism 3 through the first return branch pipe 17 and the second return branch pipe 18, respectively. The first nozzle 23 of the first spray mechanism 2 sprays out cooling water, which initially contacts the gas discharged from the inlet pipe 4 and absorbs heat. During the gas dispersion process, the contact time with the cooling water of the first spray mechanism 2 is extended under the guidance of the first guide shroud 6. Subsequently, the second nozzle 33 of the second spray mechanism 3 sprays out cooling water to perform secondary cooling on the gas. The filter plate 35 simultaneously filters impurities in the gas. Finally, the cooled gas is discharged through the outlet pipe 5, and the cooled water that has absorbed heat flows back to the water tank 12. The water inlet pipe 13 replenishes the lost water volume, and the cooling device 8 cools the circulating water in the water tank 12 in a timely manner, thereby forming a continuous, stable and efficient cooling cycle.

[0033] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
