[0002] In hydrogen bromide extraction projects, hydrogen bromide dryers play a crucial role, primarily used to remove impurities from hydrogen bromide gas to ensure the purity of the final product. However, traditional hydrogen bromide dryer cooling methods often suffer from low efficiency, which cannot meet the urgent needs of modern industrial production for high efficiency and energy saving. In order to improve the performance of hydrogen bromide dryers, reduce energy consumption, and shorten the production cycle, a new type of hydrogen bromide dryer cooling structure is urgently needed. Utility Model Content

[0003] The purpose of this invention is to provide a cooling structure for a hydrogen bromide dryer to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cooling structure for a hydrogen bromide dryer, including a dryer body, an intermediate pipe and a jacket. The intermediate pipe is disposed inside the dryer body and is used to introduce circulating cooling water to reduce the internal temperature of the dryer body. One end of the intermediate pipe is provided with a first cooling water inlet and the other end of the intermediate pipe is provided with a first cooling water outlet.

[0005] The dryer body consists of a lower tank and an upper cover, which are fixed together by four fastening components arranged in a circular array.

[0006] The jacket is wrapped around the outside of the dryer body and is used to introduce circulating cooling water to assist in cooling the dryer body. A second cooling water inlet is provided at the left end of the jacket, and a second cooling water outlet is provided at the right end of the jacket.

[0007] Preferably, the end of the first cooling water inlet pipe away from the intermediate pipe passes through the dryer body and extends to its exterior, and the end of the first cooling water outlet pipe away from the intermediate pipe passes through the dryer body and extends to its exterior.

[0008] Preferably, the dryer body is filled with an adsorbent, which is used to adsorb impurities in hydrogen bromide gas.

[0009] Preferably, the dryer body has an upper gas outlet and an upper nitrogen inlet at the top, and a lower gas inlet and a lower nitrogen outlet at the bottom.

[0010] Preferably, the jacket fits tightly against the outer wall of the dryer body, forming a good heat conduction interface.

[0011] Preferably, each of the fastening components includes an upper mounting base and a lower mounting base. A rotating handle is rotatably connected to the top of each upper mounting base. One end of the top of each rotating handle is provided with an upwardly curved notch. A limit buckle is fixedly connected to the top of each lower mounting base.

[0012] Preferably, the jacket has a guide plate inside, and the guide plate is spiral-shaped.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] First, this invention achieves comprehensive cooling of both the interior and exterior of the dryer through the synergistic effect of the intermediate pipe and the jacket. The intermediate pipe is located inside the dryer body and directly circulates cooling water to reduce the internal temperature; while the jacket wraps around the outside of the dryer body and assists in cooling with circulating cooling water. This combined internal and external cooling method significantly improves cooling efficiency, enabling the dryer to reach the required operating temperature more quickly and shortening the cycle of adsorption, regeneration, and cooling. Due to the improved cooling efficiency, the adsorbent can recover to room temperature more quickly, and the time required for the entire cycle of adsorption, regeneration, and cooling is greatly shortened. Therefore, the cooling structure of the hydrogen bromide dryer of this invention helps to improve production efficiency, reduce production costs, and meet the demands of modern industrial production for high efficiency and energy saving.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides the following technical solution:

[0023] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The cooling structure of the hydrogen bromide dryer includes a dryer body 1, an intermediate pipe 2 and a jacket 3. The intermediate pipe 2 is located inside the dryer body 1 and is used to introduce circulating cooling water to reduce the internal temperature of the dryer body 1. One end of the intermediate pipe 2 is provided with a first cooling water inlet 4 and the other end of the intermediate pipe 2 is provided with a first cooling water outlet 5.

[0024] The dryer body 1 consists of a lower tank 11 and an upper cover 12, which are fixed together by four fastening components arranged in a ring array.

[0025] The jacket 3 is wrapped around the outside of the dryer body 1 and is used to introduce circulating cooling water to assist in cooling the dryer body 1. The left end of the jacket 3 is provided with a second cooling water inlet 6, and the right end of the jacket 3 is provided with a second cooling water outlet 7.

[0026] With the above technical solution, the intermediate pipe 2 is set inside the dryer body 1. Through the first cooling water inlet 4 at one end and the first cooling water outlet 5 at the other end, circulating cooling water can flow in the intermediate pipe 2, thereby reducing the temperature inside the dryer body 1. The jacket 3 is wrapped around the outside of the dryer body 1. Through the second cooling water inlet 6 at the left end and the second cooling water outlet 7 at the right end, circulating cooling water can also flow in the jacket 3, further assisting in cooling the dryer body 1. Through the combined internal and external cooling method, the temperature of the dryer body 1 can be controlled more effectively, so that the temperature inside the dryer body 1 can be quickly reduced to room temperature to meet the requirements of adsorbent adsorption conditions and shorten the cycle of adsorption, regeneration and cooling. The dryer body 1 is connected by the lower tank 11 and the upper cover 12 through four annular array fastening components to form a detachable structure, which facilitates adsorbent replacement or internal maintenance.

[0027] The end of the first cooling water inlet 4, away from the intermediate pipe 2, passes through the dryer body 1 and extends to its exterior. The end of the first cooling water outlet 5, away from the intermediate pipe 2, passes through the dryer body 1 and extends to its exterior.

[0028] Through the above technical solution, the first cooling water inlet 4 and the first cooling water outlet both penetrate the dryer body 1 and extend to its outside, so that the circulating cooling water can be introduced into the intermediate pipe 2 from the outside of the dryer body 1, and after cooling is completed, it can be led out from the intermediate pipe 2 to the outside of the dryer body 1, which facilitates connection with the external cooling water circulation system.

[0029] The dryer body 1 is filled with an adsorbent, which is used to adsorb impurities in hydrogen bromide gas.

[0030] Through the above technical solution, the dryer body 1 is filled with adsorbent, which is used to adsorb impurities in hydrogen bromide gas. With the help of the cooling structure, the adsorbent can be kept at a suitable temperature to ensure its adsorption performance.

[0031] The dryer body 1 has an upper gas outlet and an upper nitrogen inlet at the top, and a lower gas inlet and a lower nitrogen outlet at the bottom.

[0032] With the above technical solution, the top of the dryer body 1 is provided with an upper gas outlet and an upper nitrogen inlet, and the bottom is provided with a lower gas inlet and a lower nitrogen outlet, which facilitates the entry and exit of gas and the replacement operation of nitrogen. During the hydrogen bromide drying process, the gas enters from the bottom, is adsorbed by the adsorbent, and is discharged from the top; while nitrogen is used for purging during the replacement or regeneration process.

[0033] The jacket 3 fits tightly against the outer wall of the dryer body 1, forming a good heat conduction interface.

[0034] Through the above technical solution, the jacket 3 is tightly attached to the outer wall of the dryer body 1, which can form a good heat conduction interface, so that the circulating cooling water in the jacket 3 can more effectively absorb the heat outside the dryer body 1, thereby improving the cooling efficiency, ensuring the uniform reduction of the internal temperature of the dryer body 1, and maintaining the adsorbent at a suitable temperature.

[0035] Each fastening assembly includes an upper mounting base 13 and a lower mounting base 14. Each upper mounting base 13 is rotatably connected to a rotating handle 15 at its top. Each rotating handle 15 has an upwardly curved notch at one end of its top. Each lower mounting base 14 is fixedly connected to a limit buckle 16 at its top.

[0036] With the above technical solution, the upper mounting base 13 is fixed to the upper cover 12, and the top is rotatably connected to the rotating handle. The lower mounting base 14 is fixed to the lower tank 11, and the top is provided with a limit buckle 16. When the rotating handle is rotated to the top of the limit buckle 16, its notch is inserted into the limit buckle 16, and the upper cover 12 is pressed by leverage to ensure sealing.

[0037] The jacket 3 has a guide plate 17 inside, which is spiral in shape.

[0038] Through the above technical solution, the spiral guide plate 17 can force the cooling water to flow along the spiral path, increase the degree of turbulence, break the laminar boundary layer, and improve the heat transfer coefficient. Compared with the straight channel, the spiral flow channel makes the jacket heat transfer efficiency higher and the temperature uniformity better.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
