Technical Field

[0001] This utility model relates to the field of ammonia recovery technology, and in particular to a condensation device that facilitates the recycling and reuse of ammonia. Background Technology

[0002] Ammonia is a commonly used chemical raw material in industrial production. In the desulfurization of coke oven flue gas, the ammonia method is used for desulfurization. During the desulfurization process, due to the high temperature of the coke oven, some of the ammonia evaporates into ammonia gas. The ammonia gas rises and is discharged with the hot gas, resulting in some waste. In order to save energy, it is necessary to recover and reuse the evaporated ammonia gas.

[0003] Current condensation devices for ammonia water recovery and recycling typically cool the water tank directly during operation, which is not very effective. They also consume a lot of electricity due to external influences and are not easy to control the ammonia water pump to automatically extract ammonia water. Therefore, we propose a condensation device that facilitates ammonia water recovery and recycling to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a condensation device that facilitates the recovery and recycling of ammonia.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A condensation device for easy ammonia water recovery and recycling includes a base plate, a circulating chiller mounted above the base plate, the circulating chiller having an outlet pipe and a return pipe, and further includes: Device cylinder; A condensation mechanism is located inside the device cylinder and is used to condense ammonia gas. The outlet water pipe and the return water pipe both pass through the device cylinder and are connected to the condensation mechanism. A storage mechanism is located at the upper end of the base plate; it is used to store ammonia water, and the storage mechanism is connected to the condensation mechanism.

[0006] As a further improvement of this utility model, the condensation mechanism includes a spiral condenser tube disposed inside the device cylinder, a spiral cold water sleeve sleeved on the outside of the spiral condenser tube, an ammonia water outlet pipe connected to the lower end of the spiral condenser tube, an ammonia gas pipe connected to the upper end of the spiral condenser tube, the ammonia gas pipe and the ammonia water outlet pipe both penetrating the spiral cold water sleeve, the water outlet pipe being connected to the side wall near the lower end of the spiral cold water sleeve, and the water return pipe being connected to the side wall near the upper end of the spiral cold water sleeve.

[0007] As a further improvement of this utility model, the storage mechanism includes a storage box and a pump set on the upper part of the base plate. The input end of the pump is connected to the storage box, and the output end of the pump is connected to an ammonia supply pipe. The ammonia outlet pipe is connected to the storage box.

[0010] As a further improvement of this utility model, three fixing rods are fixed to the bottom of the device cylinder, and the lower end of the fixing rods is fixed to the upper end of the base plate.

[0011] The beneficial effects of this utility model are: The spiral condenser tube adopts a spiral structure design, which significantly extends the flow path of ammonia gas in the condenser tube, allowing the ammonia gas to fully contact and exchange heat with the cooling water in the spiral cooling water jacket, thereby improving the condensation efficiency. At the same time, the outer fins and inner fins are respectively set on the outer and inner walls of the spiral condenser tube, which greatly increases the heat exchange area of ​​the condenser tube, making the heat exchange between ammonia gas and cooling water more complete, thereby improving the condensation and liquefaction effect.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-3A condensation device for easy ammonia water recovery and recycling includes a base plate 1, a circulating chiller 8 set above the base plate 1, an outlet pipe 6 and a return pipe 7 on the circulating chiller 8, and also includes a device cylinder 5, with three fixing rods 2 fixed at the bottom of the device cylinder 5, and the lower ends of the fixing rods 2 fixed to the upper end of the base plate 1. A condensing mechanism, located inside the device cylinder 5, is used to condense ammonia gas. Water outlet pipe 6 and water return pipe 7 both penetrate the device cylinder 5 and connect to the condensing mechanism. The condensing mechanism includes a spiral condensing tube 13 located inside the device cylinder 5. A spiral cooling water sleeve 11 is fitted around the outside of the spiral condensing tube 13. The lower end of the spiral condensing tube 13 is connected to an ammonia water outlet pipe 12, and the upper end of the spiral condensing tube 13 is connected to an ammonia gas pipe 9. Both the ammonia gas pipe 9 and the ammonia water outlet pipe 12 penetrate the spiral cooling water sleeve 11. The water outlet pipe 6 connects to the spiral condensing tube 13. The water jacket 11 is connected to the side wall near the lower end, and the return water pipe 7 is connected to the side wall near the upper end of the spiral cooling water jacket 11. The cold water output from the circulating chiller 8 can be introduced into the spiral cooling water jacket 11 through the outlet water pipe 6, and the ammonia gas in the coke oven can be introduced into the spiral condenser 13 through the ammonia gas pipe 9. The ammonia gas and the cold water in the spiral cooling water jacket 11 are condensed and liquefied by heat exchange through the spiral condenser 13 to form ammonia water. The hot water after heat exchange can return to the circulating chiller 8 through the return water pipe 7 for recooling.

[0016] A storage mechanism is located on the upper end of the base plate 1; it is used to store ammonia water. The storage mechanism is connected to the condensation mechanism. The storage mechanism includes a storage tank 4 and a pump 3 located on the upper end of the base plate 1. The input end of the pump 3 is connected to the storage tank 4, and the output end of the pump 3 is connected to an ammonia water supply pipe 10. The ammonia water outlet pipe 12 is connected to the storage tank 4. The ammonia water condensed inside the condensation pipe 13 can enter the storage tank 4 through the ammonia water outlet pipe 12 for storage. The ammonia water inside the storage tank 4 can be pumped out by the pump 3 for supply and output.

[0017] Furthermore, the outer wall of the spiral condenser tube 13 is provided with outer fins 14, and the inner wall of the spiral condenser tube 13 is provided with inner fins 15. The spiral condenser tube 13, outer fins 14, and inner fins 15 are integrally formed. By setting the outer fins 14 and inner fins 15, the heat exchange area of ​​the condenser tube 13 can be increased, making the ammonia condensation efficiency in the condenser tube 13 higher.

[0018] In use, the circulating chiller 8 first delivers cooling water to the side wall near the lower end of the spiral cooling water jacket 11 through the outlet pipe 6. The cooling water flows from bottom to top in the spiral cooling water jacket 11. Simultaneously, ammonia gas from the coke oven enters the upper end of the spiral condenser 13 through the ammonia gas pipe 9. The ammonia gas flows from top to bottom in the spiral condenser 13. The outer fins 14 on the outer wall and the inner fins 15 on the inner wall of the spiral condenser 13 fully contact and exchange heat with the cooling water in the spiral cooling water jacket 11. After efficient heat exchange with cooling water in the condenser tube 13, the ammonia water is condensed and liquefied to form ammonia water. The condensed ammonia water flows into the storage tank 4 through the ammonia water outlet pipe 12 at the lower end of the spiral condenser tube 13. The hot water after heat exchange with ammonia gas flows back to the circulating chiller 8 through the return water pipe 7 from the side wall near the upper end of the spiral cooling water jacket 11 for recooling. When the ammonia water in the storage tank 4 is needed, the pump 3 draws ammonia water from the storage tank 4 through the input end and supplies the ammonia water through the ammonia water supply pipe 10 at the output end.
