[0002] The existing pipeline from the 3-cyanopyridine reactor to the absorption tower is arranged along the platform floor. During the experiment, the process gas temperature is approximately 370℃. The process gas cools and accumulates at the right-angle bends, which can easily lead to pipeline blockage. This not only directly affects the reaction but also the yield calculation. Utility Model Content

This invention can solve the problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A 3-cyanide reactor to absorption tower pipeline device includes a reactor, the reactor being connected to the absorption tower via a bent pipe, and a spray device installed at the right angle of the bent pipe, the spray device being used to prevent process gas from accumulating at the right angle and clogging the bent pipe.

[0006] A circulation pump is installed on one side of the absorption tower. The inlet of the circulation pump is connected to the lower end of the absorption tower through a pipeline, and the outlet of the circulation pump is connected to the upper end of the absorption tower through a pipeline. A spraying device is also connected to the pipeline connected to the outlet of the circulation pump through a hose.

[0007] Preferably, the upper end of the reactor is connected to the feed pipe via a flange, and the bottom of the reactor is connected to the bent pipe via a flange.

[0008] Preferably, the upper end of the absorption tower is connected to an exhaust pipe via a flange, and the bottom of the absorption tower is connected to a bent pipe via a flange.

[0009] Preferably, the spraying device includes a spray pipe and a spray head. The spray pipe is located at the right angle of the curved pipe, and the spray head is installed on the spray pipe. The spray pipe is connected to a flexible hose.

[0010] Preferably, a motor is installed on the outer wall of the curved pipe, the output shaft of the motor is mounted on a support frame, and the support frame is installed on the inner wall of the curved pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention first involves adding absorbent liquid to the absorption tower, starting the circulation pump and opening the spray device. Then, various reaction raw materials enter the reactor through the feed pipe to react. The reacted material enters the absorption tower along the curved pipe to be absorbed. Some unabsorbed process gas enters the next process through the exhaust pipe to be absorbed. During the process gas reaction and absorption, the circulation pump extracts the absorbent liquid added to the absorption tower and delivers it to the spray pipe through a hose. The spray head sprays the process gas that accumulates at the right angle of the curved pipe, which can prevent the process gas from accumulating at the right angle and clogging the curved pipe. This solves the problem of reaction material clogging in the curved pipe and affecting the reaction yield calculation.

[0020] 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.

[0021] To address the issue of existing process gases accumulating and cooling at right-angle bends, which can easily lead to pipe blockage and directly affect both the reaction process and yield calculations, please refer to [reference needed]. Figures 1-5 The following technical solution is provided in this embodiment:

[0022] A 3-cyanide reactor to absorber pipeline device includes a reactor 1, which is connected to an absorber 3 via a bent pipe 2.

[0023] The upper end of reactor 1 is connected to feed pipe 11 via flange, and the bottom of reactor 1 is connected to bent pipe 2 via flange.

[0024] The upper end of the absorption tower 3 is connected to the exhaust pipe 31 via a flange, and the bottom of the absorption tower 3 is connected to the bent pipe 2 via a flange.

[0025] A spray device 4 is installed at the right angle of the bent pipe 2. The spray device 4 is used to prevent process gas from accumulating at the right angle and clogging the bent pipe 2.

[0026] A circulation pump 5 is installed on one side of the absorption tower 3. The inlet of the circulation pump 5 is connected to the lower end of the absorption tower 3 through a pipeline, and the outlet of the circulation pump 5 is connected to the upper end of the absorption tower 3 through a pipeline. The pipeline connected to the outlet of the circulation pump 5 is also connected to the spray device 4 through a hose 6.

[0027] It should be noted that during the process gas reaction and absorption, the circulating pump 5 extracts the absorbent added to the absorption tower 3 and delivers it to the spray device 4 through the hose 6. The spray device 4 sprays the process gas that accumulates at the right angle of the bend pipe 2, which can prevent the process gas from accumulating at the right angle and clogging the bend pipe 2. This solves the problem of the reactants clogging in the bend pipe 2 and affecting the reaction yield. Moreover, the spray liquid sprayed by the spray device 4 is the absorbent in the absorption tower 3, so the absorbent can be fully utilized and no more absorbent is wasted.

[0028] In this embodiment, the spraying device 4 includes a spray pipe 41 and a spray head 42. The spray pipe 41 is located at the right angle of the curved pipe 2, and the spray head 42 is installed on the spray pipe 41. The spray pipe 41 is connected to the hose 6. A motor 21 is installed on the outer wall of the curved pipe 2. The output shaft of the motor 21 is installed on the support frame 22. The support frame 22 is installed on the inner wall of the curved pipe 2. One end of the spray pipe 41 is located inside the support frame 22, and the spray pipe 41 is connected to the output shaft of the motor 21. The spray pipe 41 is driven by the motor 21 to rotate on the support frame 22 to adjust the spraying angle.

[0029] It should be noted that when the spraying device 4 sprays the spraying liquid, the motor 21 can drive the spraying pipe 41 to rotate on the support frame 22 to adjust the spraying angle. This can better spray the process gas that accumulates at the right angle of the curved pipe 2, so that the process gas no longer accumulates at the right angle of the curved pipe 2, thus avoiding blockage of the curved pipe 2 and affecting the calculation of the reaction yield.

[0030] Working principle: First, absorbent liquid is added to absorption tower 3, circulation pump 5 is turned on and spray device 4 is opened. Then, various reaction raw materials enter reactor 1 from feed pipe 11 to react. The reacted material enters absorption tower 3 along curved pipe 2 and is absorbed. Some unabsorbed process gas enters the next process through exhaust pipe 31 to be absorbed. During the process gas reaction and absorption, circulation pump 5 extracts the absorbent liquid added to absorption tower 3 and delivers it to spray pipe 41 through hose 6. Spray head 42 sprays the process gas that accumulates at the right angle of curved pipe 2, which can prevent process gas from accumulating at the right angle and clogging curved pipe 2. It can solve the problem of reaction material clogging in curved pipe 2 and affecting the reaction yield calculation. Moreover, the spray liquid sprayed by spray head 42 is the absorbent liquid in absorption tower 3, so the absorbent liquid can be fully utilized and no more absorbent liquid is wasted.
