[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] Please see Figures 1-7 As shown, a hydrogen feed cooling device for a hydrogen sulfide synthesis tower includes a first cylinder 1 and a second cylinder 2. The second cylinder 2 is located below the first cylinder 1. Multiple support columns 3 are symmetrically installed at the bottom edge of the second cylinder 2. Anti-slip pads 4 are fixedly connected to the bottom ends of the support columns 3. By setting the anti-slip pads 4, the friction between the support columns 3 and the ground can be increased, effectively preventing the first cylinder 1 from shifting or tipping due to external forces, thus improving placement stability. The device also includes a second cooling component 10 installed inside the first cylinder 1 to accelerate hydrogen cooling. By setting the second cooling component 10, it can absorb the heat carried by the high-temperature hydrogen after contact with it, thereby reducing the temperature of the high-temperature hydrogen before it enters the hydrogen sulfide synthesis tower. This effectively reduces the heat carried into the hydrogen sulfide synthesis tower by the hydrogen, which is beneficial for controlling the reactor bed temperature and preventing frequent overheating of the catalyst bed. A hollow jacket 7 is coaxially arranged on the inner wall of body 1. Inside the hollow jacket 7, a first cooling component 9 is provided to increase the contact area between hydrogen and the cold source. By setting the first cooling component 9, the hydrogen can come into contact with the high temperature from one side of the hollow jacket 7, further increasing the contact area between the hydrogen and the cooling component, making the hydrogen cool down more quickly and with better cooling effect. A feeding component 17 is set on one side of the second cylinder 2 to facilitate the input of high temperature hydrogen into the first cylinder 1. By setting the feeding component 17, the high temperature hydrogen can enter the first cylinder 1 before entering the hydrogen sulfide synthesis tower for pre-cooling treatment, so as to facilitate the subsequent hydrogen sulfide synthesis work.

The top of the first cylinder body 1 and the bottom of the sealing top cover 5 are fixedly connected with a first flange 16. The first flange 16 is provided with a through slot 18 corresponding to the collecting pipe 13. The sealing gasket 19 is fixedly connected to the inner wall of the through slot 18. One end of the collecting pipe 13 penetrates through the through slot 18 to the outside of the first cylinder body 1. The first flange 16 is connected by bolts, as shown in Figure 5 The second liquid inlet 12 is used to facilitate the entry of external cooling liquid into the heat exchange pipe 107. After the cooling liquid absorbs heat, it is discharged to the outside of the first cylinder body 1 through the second liquid outlet 11, and can enter the waste heat recovery. By arranging the sealing gasket 19, the sealing performance between the first cylinder body 1 and the sealing top cover 5 can be improved, so as to avoid leakage of hydrogen.

External high-temperature hydrogen enters the inside of the second cylinder body 2 and the first cylinder body 1 through the spray outlet 173. This facilitates the subsequent cooling work of high-temperature hydrogen.

[0032] Working principle: First, the staff introduces the external high-temperature hydrogen to be cooled into the inside of the second cylinder body 2 and the first cylinder body 1 through the feeding assembly 17. Then, through the second cooling assembly 10, the contact area with the high-temperature hydrogen can be maximized without hindering the passage of the high-temperature hydrogen, so that the heat exchange between the high-temperature hydrogen and the heat-conducting cylinder 103 is more complete. In combination with the first cooling assembly 9, the contact area between the high-temperature hydrogen and the cooling component is further increased. In this way, the temperature of the high-temperature hydrogen is reduced before it enters the hydrogen sulfide synthesis tower, effectively reducing the heat brought into the hydrogen sulfide synthesis tower by the hydrogen, which is conducive to controlling the bed temperature of the reactor and eliminating the frequent over-temperature of the catalyst bed. At the same time, through the limiting stud 105 and the fastening bolt 106, the second cooling assembly 10 can be easily disassembled and repaired, and the dirt on the outside of the second cooling assembly 10 can be easily cleaned and maintained.
