Technical Field

[0001] The utility model relates to the technical field of vinyl ether condensation, in particular to a condensing unit used for preparing vinyl ether. Background Art

[0002] In industry, vinyl ether is usually prepared by adding acetylene and ethanol into a reactor containing an alkali metal salt solution. The vinyl ether produced by the reaction needs to be condensed and stored for later use. Existing condensation devices generally use a circulating cooling method for cooling.

[0003] However, when using this method for cooling, in actual use, the condenser part is generally in a fixed state, and it is difficult to fully contact the vinyl ethyl ether to be cooled, so the actual cooling efficiency will be greatly reduced. In addition, if impurities adhere to the surface of the condenser part after use, the condenser part needs to be cleaned to ensure its condensation effect, and it is also difficult to clean if it is in a fixed state.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3 A condensing unit for preparing vinyl ether comprises a shell 1, a feed port 4 is installed at the inner top of the shell 1, a discharge port is arranged at the inner bottom of the shell 1, manual valves are installed in the feed port 4 and the discharge port, and a plurality of supporting legs 2 are installed at the lower end of the shell 1;

[0020] The condensing mechanism includes a spiral temperature conducting tube 10 disposed in the shell 1. The liquid inlet and liquid outlet of the spiral temperature conducting tube 10 are both connected to a vertical tube 11. The other ends of the two vertical tubes 11 penetrate the inner wall of the shell 1 (rotating sealing pads are installed at the penetration points to ensure the sealing of the rotating connection) and are rotatably connected to the inner wall of the shell 1. A cooling box 5 is installed at the upper end of the shell 1.

[0021] Among them, a semiconductor refrigeration element 6 is installed at the upper end of the cooling box 5, and the semiconductor refrigeration element 6 is composed of a semiconductor refrigeration sheet and a heat dissipation fan. This is the prior art. The refrigeration end of the semiconductor refrigeration element 6 extends into the cooling box 5. A pump body 16 is installed at the upper end of the shell 1. The liquid inlet end of the pump body 16 is connected to the right space of the cooling box 5. The left space of the cooling box 5 is connected to a second connecting pipe 8. The other end of the second connecting pipe 8 is connected to the lower end of the lower vertical pipe 12 through a second rotary joint 15. The water outlet end of the pump body 16 is connected to a first connecting pipe 7. The other end of the first connecting pipe 7 is connected to the upper end of the upper vertical pipe 12 through a first rotary joint 9. The cooling box 5, the two vertical pipes 12, the spiral temperature conducting pipe 10, the first connecting pipe 7 and the second connecting pipe 8 are all filled with temperature conducting oil;

[0022] It also includes a rotating mechanism, which cooperates with the condensing mechanism. The rotating mechanism includes a motor 3 installed at the upper end of the shell 1, and the vertical pipe 12 located above and the output shaft of the motor 3 are both equipped with pulleys 14. The two pulleys 14 are connected by a transmission belt 13. A plurality of inclined stirring rods 11 are fixedly connected to the inner side of the spiral temperature conducting tube 10.

[0023] In the present utility model, in actual use, when it is necessary to cool the high-temperature vinyl ether solution in the shell 1, the pump body 16 and the semiconductor refrigeration element 6 are started at the same time, so that the temperature of the temperature-conducting oil will be reduced when passing through the semiconductor refrigeration element 6, and then enter the spiral temperature-conducting tube 10, and the vinyl ether solution is cooled by heat exchange. Since it is a circulating liquid cooling, the continuity of cooling is strong. In this process, the motor 3 can also be started at the same time. The start of the motor 3 will be driven by the pulley 14, so that the two vertical pipes 12 drive the spiral temperature-conducting tube 10 to rotate, so that the spiral temperature-conducting tube 10 is fully in contact with the vinyl ether solution, improving the uniformity of cooling. In this process, the inclined stirring rod 11 will also rotate accordingly to stir the solution, further promote the flow of the solution, and further improve the uniformity of cooling;

[0024] Subsequently, the discharge port is opened to discharge the vinyl ether solution. When the spiral temperature conducting tube 10 needs to be cleaned, it is only necessary to add the cleaning liquid from the feed port 4, and then start the motor 3 to allow the spiral temperature conducting tube 10 and the cleaning liquid to move relative to each other to achieve self-cleaning, thereby facilitating the cleaning of the spiral temperature conducting tube 10.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
