UTILITY MODEL CONTENT

[0004] The main purpose of the utility model is to provide a stripping tower for hydrogen production from methanol, which can effectively solve the problem that when the feed liquid is discharged into the tower body through the water inlet pipe, due to the limited discharge range, the mixing range of the feed liquid and the gas discharged into the tower body is limited, the feed liquid is concentrated in a local area, resulting in too high gas-liquid ratio in this area and insufficient gas-liquid contact in other areas.

[0005] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows:

[0006] A stripping tower for hydrogen production from methanol, comprising a tower body, wherein the lower end of the tower body is provided with a water tank, and a circular hole is formed through the inner bottom surface of the tower body;

[0007] An air inlet pipe and a flushing pipe are fixedly installed on the outer wall of the tower body, an inlet pipe is fixedly installed through the upper end of the tower body, a horn sleeve is rotatably installed on the inlet pipe body through a bearing, and a plurality of water holes are formed through the inner bottom surface of the horn sleeve;

[0008] A distributor is arranged in the tower body.

[0009] As a preferred embodiment, a bevel gear ring is sleeved on the outer wall of the horn sleeve, and a driving assembly for driving the bevel gear ring to rotate is arranged on the outer wall of the tower body.

[0010] Preferably, the drive assembly includes a bracket, which is fixedly installed on the outer wall of the tower body. A motor is fixedly installed on one side of the bracket, and one end of the motor output shaft passes through the bracket and is fitted with a bevel gear, which meshes with a bevel gear ring.

[0012] Preferably, an annular insert plate is fixedly installed on the upper surface of the sealing ring.

[0013] Preferably, the lower end surface of the liquid inlet pipe is provided with an annular slot, and the annular insert plate is inserted into the annular slot.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The stripping medium is introduced into the tower body through the air inlet pipe. The light components in the liquid discharged into the tower body from the liquid inlet pipe are carried out through the air outlet of the tower body. When the liquid is introduced, the liquid enters the bell sleeve through the liquid inlet pipe and enters the distributor in the tower body through several round holes, thereby increasing the liquid discharge range and making it more uniformly mixed with the stripping medium. Then the remaining liquid after mixing enters the water tank through the round holes, which makes it convenient for the staff to recycle and reuse. Attached Figure Description

[0021] 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.

[0022] like Figures 1-4 As shown, a stripping tower for methanol-to-hydrogen includes a tower body 1, a water tank 2 at the lower end of the tower body 1, and a circular hole 3 through-hole on the bottom surface of the inner side of the tower body 1.

[0023] An air inlet pipe 4 and a flushing pipe 401 are fixedly installed on the outer wall of the tower body 1. A liquid inlet pipe 5 is fixedly installed through the upper end of the tower body 1. A horn sleeve 7 is rotatably installed on the body of the liquid inlet pipe 5 through a bearing 6. Several water holes 8 are opened through the bottom surface of the horn sleeve 7.

[0024] A distributor 14 is installed inside the tower body 1.

[0025] Stripping medium is introduced into tower body 1 through air inlet pipe 4. Light components in the liquid discharged into tower body 1 from liquid inlet pipe 5 are carried out through air outlet of tower body 1. When liquid is introduced, liquid enters trumpet sleeve 7 through liquid inlet pipe 5 and enters distributor 14 inside tower body 1 through several round holes 3, thereby increasing the liquid discharge range and enabling it to mix more evenly with stripping medium. The remaining liquid after mixing then enters water tank 2 through round holes 3 for easy recycling by staff.

[0026] In another embodiment of this utility model, a conical toothed ring 9 is fitted on the outer wall of the horn sleeve 7, and a drive assembly 10 for driving the conical toothed ring 9 to rotate is provided on the outer wall of the tower body 1.

[0027] The drive assembly 10 includes a bracket 1001, which is fixedly installed on the outer wall of the tower body 1. A motor 1002 is fixedly installed on one side of the bracket 1001. One end of the output shaft of the motor 1002 passes through the bracket 1001 and is fitted with a bevel gear 1003. The bevel gear 1003 meshes with the bevel gear ring 9.

[0028] The staff started the motor 1002, which caused its output shaft to drive the bevel gear 1003 to rotate. Under the meshing action of the bevel gear 1003 and the bevel gear ring 9, the horn sleeve 7 rotated, causing the water hole 8 to rotate, thereby further increasing the discharge range of the liquid.

[0029] In another embodiment of this utility model, a sealing ring 11 is fixedly installed on the inner wall of the speaker sleeve 7.

[0030] An annular insert plate 12 is fixedly installed on the upper surface of the sealing ring 11.

[0031] An annular slot 13 is provided on the lower end surface of the liquid inlet pipe 5, and the annular insert plate 12 is inserted into the annular slot 13.

[0032] The interlocking of the annular insert plate 12 and the annular slot 13 improves the sealing of the horn sleeve 7 and the inlet of the liquid inlet pipe 5, preventing liquid leakage.

[0033] The working principle of a stripping tower for methanol-to-hydrogen production:

[0034] In use, stripping medium is introduced into the tower body 1 through the air inlet pipe 4. Light components in the liquid discharged into the tower body 1 from the liquid inlet pipe 5 are carried out through the air outlet of the tower body 1. When the liquid is introduced, the liquid enters the bell sleeve 7 through the liquid inlet pipe 5 and enters the distributor 14 inside the tower body 1 through several round holes 3, thereby increasing the liquid discharge range and enabling it to be mixed more evenly with the stripping medium. The remaining liquid after mixing then enters the water tank 2 through the round holes 3 for easy recycling and reuse by the staff.

[0035] 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.
