Technical Field
[0001] This utility model relates to the field of ammonia absorption tower technology, specifically to an ammonia absorption tower for guanidine carbonate refining with a buffer structure. Background Technology
[0002] In the industrial production of ammonia, the absorption tower plays a crucial role. As the core equipment of the ammonia production process, the main function of the absorption tower is to separate and purify ammonia gas from ammonia-containing mixed gas to obtain high-purity ammonia products. The working principle of the absorption tower is mainly based on the combination of chemical reaction and physical absorption processes. Inside the tower, a specific absorbent comes into full contact with the ammonia-containing mixed gas, and ammonia gas is separated from the mixed gas through chemical reaction or physical adsorption. In this process, the selection of absorbent is crucial, as it directly affects the absorption efficiency and purification effect of ammonia gas.
[0003] If the gas enters the ammonia absorption tower too quickly during use, it can affect the mixing and reaction between the absorbent and the gas.
[0004] Therefore, an ammonia absorption tower for guanidine carbonate refining with a buffer structure is needed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an ammonia absorption tower for guanidine carbonate refining with a buffer structure, so as to solve the problem mentioned in the background art that the flue gas enters the ammonia absorption tower at too high a speed, which is not conducive to the reaction between the absorbent and the gas.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an ammonia absorption tower for guanidine carbonate refining with a buffer structure, comprising an absorption tower body, an inlet pipe and an exhaust pipe, a drain pipe installed at the bottom right side of the absorption tower body, an inlet pipe installed on the left side of the absorption tower body, a buffer assembly provided inside the absorption tower body, the buffer assembly comprising a roller, a positioning shaft and a lever plate, the roller being provided inside the absorption tower body, a positioning shaft being installed at both ends of the roller, and a lever plate being fixed to the outer wall of the roller.
[0007] As a further technical solution of this utility model, several actuating plates are fixed on the outer side wall of the roller, and the several actuating plates are arranged in a ring.
[0008] As a further technical solution of this utility model, a processing box is installed inside the main body of the absorption tower, a diversion pipe is installed inside the processing box, and a wire mesh is installed inside the diversion pipe.
[0009] As a further technical solution of this utility model, several diversion pipes are installed inside the processing box, and the several diversion pipes are distributed at equal intervals.
[0010] As a further technical solution of this utility model, a spray frame is provided above the treatment box, a spray pipe is installed at the bottom of the spray frame, the bottom end of the spray pipe extends into the interior of the diversion pipe, and a nozzle is installed at the bottom end of the spray pipe.
[0011] As a further technical solution of this utility model, a drug inlet pipe is installed at the top of the spray frame, and the right side of the drug inlet pipe extends to the outside of the absorption tower body.
[0012] As a further technical solution of this utility model, a demister is installed at the top of the inside of the absorption tower body, and an exhaust pipe is installed at the top of the absorption tower body.
[0013] As a further technical solution of this utility model, a heat sink is installed on the outer wall of the diversion pipe, an inlet pipe is installed on the right side of the absorption tower body, and a drain pipe is installed on the left side of the absorption tower body.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a roller, the roller is movably installed inside the main body of the absorption tower with the assistance of the positioning shaft, directly facing the inlet of the gas inlet pipe. When the gas enters the main body of the absorption tower along the gas inlet pipe, it impacts the roller. With the assistance of multiple sets of actuating plates on the surface of the roller, the roller can rotate, thereby absorbing the impact of the gas and assisting the gas to move slowly upward, thus realizing the buffering function of the ammonia absorption tower when the gas enters.
[0015] By setting up diversion pipes and wire mesh, multiple diversion pipes are inserted through the inside of the treatment box for use. After the gas enters, it can be dispersed to the inside of the multiple diversion pipe groups, realizing the auxiliary diversion function of the gas entering the ammonia absorption tower.
[0016] By incorporating a treatment tank, an inlet pipe, and an outlet pipe, as the gas moves upward along the distribution pipe, heat is transferred to the interior of the treatment tank with the assistance of heat sinks. Liquid is then introduced into the treatment tank via the inlet and outlet pipes. During the circulation process inside the treatment tank, the heat assists in heating the liquid and cooling the gas. Simultaneously, the heat of the gas can be utilized, thus realizing the cooling function of the ammonia absorption tower. Attached Figure Description

[0022] 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.
[0023] Please see Figure 1-4 An embodiment of this utility model provides: an ammonia absorption tower for guanidine carbonate refining with a buffer structure, including an absorption tower body 1, an inlet pipe 3 and an exhaust pipe 15. A drain pipe 2 is installed at the bottom right side of the absorption tower body 1, and an inlet pipe 3 is installed on the left side of the absorption tower body 1. A buffer assembly is provided inside the absorption tower body 1. The buffer assembly includes a roller 4, a positioning shaft 5 and a deflecting plate 6. The roller 4 is provided inside the absorption tower body 1. Positioning shafts 5 are installed at both ends of the roller 4. A deflecting plate 6 is fixed on the outer wall of the roller 4. Several deflecting plates 6 are fixed on the outer wall of the roller 4 and the several deflecting plates 6 are arranged in a ring.
[0024] Specifically, such as Figure 1 As shown, when the gas enters the body 1 of the absorption tower through the inlet pipe 3, it collides with the inner roller 4. During this process, the actuating plate 6 on the outer wall of the roller 4 can be pushed to drive the roller 4 to rotate. In this way, the kinetic energy of the gas can be absorbed, causing it to move slowly inside the body 1 of the absorption tower.
[0025] The absorption tower body 1 is equipped with a treatment box 7 inside, and a diversion pipe 8 is installed inside the treatment box 7. Several diversion pipes 8 are installed inside the treatment box 7 and are distributed at equal intervals. A wire mesh 9 is installed inside the diversion pipe 8. A spray frame 10 is set above the treatment box 7. A spray pipe 11 is installed at the bottom of the spray frame 10. The bottom of the spray pipe 11 extends into the interior of the diversion pipe 8. A nozzle 12 is installed at the bottom of the spray pipe 11. A chemical inlet pipe 13 is installed at the top of the spray frame 10. The right side of the chemical inlet pipe 13 extends to the outside of the absorption tower body 1. A demister 14 is installed at the top inside the absorption tower body 1. An exhaust pipe 15 is installed at the top of the absorption tower body 1.
[0026] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, during use, a multi-component diversion pipe 8 is installed through the inside of the treatment box 7 to allow gas to flow in. After the gas flows into the multi-component diversion pipe 8, the nozzle 12 at the top of the diversion pipe 8 can be activated to spray the absorbent. The gas and absorbent come into contact at the wire mesh 9 to complete the reaction.
[0027] Heat sink 16 is installed on the outer wall of the diversion pipe 8, liquid inlet pipe 17 is installed on the right side of the absorption tower body 1, and liquid outlet pipe 18 is installed on the left side of the absorption tower body 1.
[0028] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, during use, liquid can be introduced into the processing tank 7 through the inlet pipe 17 and the outlet pipe 18 to flow inside. As the gas moves along the diversion pipe 8, its own heat can be transferred into the processing tank 7 with the assistance of the diversion pipe 8 and the heat sink 16. This can help heat the liquid while also cooling the gas.
[0029] Working principle: During operation, when gas enters the main body 1 of the absorption tower through the inlet pipe 3, it collides with the inner roller 4. During this process, the actuating plate 6 on the outer wall of the roller 4 can be pushed, driving the roller 4 to rotate. This absorbs the kinetic energy of the gas, causing it to move slowly inside the main body 1 of the absorption tower. Afterward, the gas can be dispersed into the interior of the multi-component flow pipes 8. Each flow pipe 8 has a nozzle 12 installed at its top. When the nozzle 12 is activated, the absorbent is sprayed, and the gas and absorbent come into contact at the wire mesh 9. After the reaction is complete, the treated gas moves upward along the diversion pipe 8, passes through the demister 14, and is discharged through the exhaust pipe 15. The liquid flows into the bottom of the absorption tower body 1 along the diversion pipe 8. With the help of the inlet pipe 17 and the outlet pipe 18, the liquid can flow inside the treatment tank 7. As the gas moves along the diversion pipe 8, its own heat can be transferred into the treatment tank 7 with the assistance of the diversion pipe 8 and the heat sink 16. This can help heat the liquid while also cooling the gas.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
