Description

Technical Field

[0001] The utility model relates to the technical field of dechlorination towers, in particular to a cooling structure of a dechlorination tower. Background Art

[0002] A certain amount of chlorine is dissolved in the brine produced by the electrolysis process. If the chlorine is not completely removed, it will corrode the pipelines of the subsequent processes and cause performance degradation. The dechlorination tower can be used to remove chlorine from the brine. The chlorine is separated from the liquid through the filling layer. The chlorine is discharged from the top of the dechlorination tower and the liquid is discharged from the bottom of the dechlorination tower.

[0003] At present, the high-temperature brine discharged from the dechlorination tower needs to be cooled by a cooler. The existing dechlorination tower coolers use a cooling medium (such as water, air or refrigerant) to exchange heat with the dechlorination product to reduce its temperature. However, due to the small number of heat exchange tubes arranged in the traditional dechlorination tower cooler, the tube diameter is too small or the design is unreasonable, resulting in insufficient overall heat exchange area and difficulty in effective heat exchange, thus affecting the cooling effect. Utility Model Content

[0004] The utility model aims to provide a cooling structure for a dechlorination tower to solve the problem in the above-mentioned background technology that the dechlorination tower cooler has insufficient overall heat exchange area due to too few heat exchange tubes, too small tube diameters or unreasonable designs, which affects the cooling effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooling structure of a dechlorination tower, comprising a cooler body, wherein both sides of the cooler body are respectively provided with a liquid inlet and a liquid outlet, and the upper and lower ends of the cooler body are respectively provided with a cold flow inlet and a cold flow outlet, and the upper and lower ends of the cooler body are respectively provided with a fixed tube sheet and a floating head tube sheet, a plurality of heat exchange tubes arranged in a square are arranged between the fixed tube sheet and the floating head tube sheet, and a baffle is also spaced between the fixed tube sheet and the floating head tube sheet.

[0006] Preferably, the heat exchange tube has a diameter of 19 mm and a thickness of 1.5 mm.

[0007] Preferably, a guide edge is provided on the edge of the baffle plate adjacent to the cooler body.

[0008] Preferably, the heat exchange tubes are vertical copper tubes with gaps between them.

[0009] Preferably, a liquid distribution groove is formed between the fixed tube plate and the top inner wall of the cooler body.

[0010] Preferably, the baffles are distributed in an up-and-down staggered manner between the fixed tube sheet and the floating head tube sheet.

[0011] Compared with the prior art, the utility model has the beneficial effect that the cooling structure of the dechlorination tower optimizes the layout of the heat exchange tubes, increases the heat exchange area, has a higher heat transfer efficiency, and thus effectively improves the cooling effect. The cooling structure of the dechlorination tower arranges a plurality of heat exchange tubes arranged in a square between the fixed tube sheet and the floating head tube sheet, replacing the traditional triangular arrangement, which can increase the number of heat exchange tubes to produce a higher heat transfer efficiency.

[0016] 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.

[0017] See also Figure 1-3The utility model provides a technical solution: a cooling structure of a dechlorination tower, comprising a cooler body 1, a liquid inlet 6 and a liquid outlet 2 are respectively arranged on both sides of the cooler body 1, and a cold flow inlet 3 and a cold flow outlet 7 are respectively arranged at the upper and lower ends of the cooler body 1, characterized in that: a fixed tube sheet 4 and a floating head tube sheet 5 are respectively arranged at the upper and lower ends inside the cooler body 1, a plurality of heat exchange tubes 8 arranged in a square are arranged between the fixed tube sheet 4 and the floating head tube sheet 5, and a baffle 9 is also arranged between the fixed tube sheet 4 and the floating head tube sheet 5, and the cooler body 1 of this structure can pass through the cold The inlet 3 transports the cooling medium to its inner wall and enters the plurality of heat exchange tubes 8. When the cooling medium flows evenly in the plurality of heat exchange tubes 8, the cooler body 1 simultaneously transports the dechlorination product fluid to be cooled to its interior through the liquid inlet 6 and contacts with the plurality of heat exchange tubes 8 for heat exchange. Since the heat exchange tubes 8 are arranged in a square shape between the fixed tube sheet 4 and the floating head tube sheet 5, the contact effect between the dechlorination product fluid and the heat exchange tubes 8 is better, with higher heat transfer efficiency, and the cooling effect of the cooler body 1 on the dechlorination product fluid is effectively improved. The diameter of the heat exchange tube 8 is 19 mm and The thickness is 1.5mm. The heat exchange tube 8 of this structure is optimized in specifications, so that more numbers can be installed on the fixed tube sheet 4 of the same specifications. The edge of the baffle 9 adjacent to the cooler body 1 is provided with a guide edge 91. The outer surface of the guide edge 91 is a circular arc surface structure. The guide edge 91 of this structure can avoid the formation of a flow dead zone at the connection between the baffle 9 and the inner wall of the cooler body 1, improve the smoothness of the dechlorination product when flowing inside the cooler body 1, and prevent the phenomenon of fluid short circuit. The heat exchange tube 8 is a vertical copper tube with gaps between each other. The heat exchange tube 8 of this structure can be kept In order to ensure good corrosion resistance and heat exchange effect, a liquid distribution groove is formed between the fixed tube sheet 4 and the top inner wall of the cooler body 1. The liquid distribution groove formed between the fixed tube sheet 4 and the top inner wall of the cooler body 1 can make the cooling medium flow into each heat exchange tube 8 evenly, ensuring the overall cooling effect of the heat exchange tube 8 on the dechlorination product. The baffles 9 are staggered up and down between the fixed tube sheet 4 and the floating head tube sheet 5. The baffles 9 of this structure can play a circulatory and progressive guiding role for the dechlorination product fluid, so that the dechlorination product fluid will have a better contact effect with the heat exchange tube 8, further improving the heat exchange efficiency.

[0018] Working principle: When the cooling structure of the dechlorination tower is used, the fluid dechlorinated by the dechlorination tower is first transported from the liquid inlet 6 to the inside of the cooler body 1 through the pump body, and the external connection of the liquid outlet 2 is used to suck the fluid. At the same time, the cooling medium is sent from the cold flow inlet 3 to the liquid distribution groove formed between the fixed tube sheet 4 and the top inner wall of the cooler body 1. When the cooling medium flows evenly into each heat exchange tube 8, the dechlorination product fluid flowing between the fixed tube sheet 4 and the floating head tube sheet 5 will fully contact with each heat exchange tube 8 for heat exchange. When the dechlorination product fluid contacts the baffle 9, the baffle 9 will return and guide the dechlorination product fluid, and the guide edge 91 can also prevent the fluid from short-circuiting at the connection between the baffle 9 and the inner wall of the cooler body 1. The dechlorination product fluid is transported from the liquid outlet 2 after heat exchange, and the used cooling medium flows into the bottom of the cooler body 1 and flows out from the cold flow outlet 7, thereby completing a series of work.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
