Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0016] The embodiments are basically as shown in the accompanying drawings: Figures 1-2 An overall structure system of an acetone vapor compressor comprises an integrated oil system base 2, a driving motor 1, a vapor compressor head 3, an outlet assembly and an inlet assembly. The integrated oil system base 2 provides lubrication for the vapor compressor head 3 and supports the driving motor 1, the vapor compressor head 3 and other components. Figure 2 As shown in the drawings, the vapor compressor head 3 comprises a volute 4, an inlet casing 15, a rotor 16, a dry gas seal 17 and a gear box 14. The inlet casing 15 is located at the gas inlet end of the volute 4, and the driving motor 1 is connected with the gear box 14. The output shaft of the gear box 14 is connected with the rotor 16 after penetrating through the connecting hole on the volute 4 and is used to drive the rotor 16 to rotate. The dry gas seal 17 is arranged between the output shaft and the connecting hole. The inlet assembly is connected with the inlet casing 15, and the outlet assembly is connected with the outlet of the volute 4.
[0017] The inlet assembly comprises an inlet pipe 13, an inlet taper pipe 11, an inlet expansion joint 12 and an inlet flowmeter 18. The small-diameter end of the inlet taper pipe 11 is connected with the inlet casing 15, and the large-diameter end of the inlet taper pipe 11 and the inlet pipe 13 are respectively connected with the two sides of the inlet expansion joint 12. The inlet flowmeter 18 is installed on the inlet pipe 13. The outlet assembly comprises an outlet pipe 7, an outlet taper pipe 5 and an outlet expansion joint 6. The small-diameter end of the outlet taper pipe 5 is connected with the outlet of the volute 4, the large-diameter end of the outlet taper pipe 5 and the outlet pipe 7 are respectively connected with the two sides of the outlet expansion joint 6. The anti-surge pipe 9 is connected with the outlet pipe 7, the anti-surge valve 10 is connected with the anti-surge pipe 9, and the cooling system 8 is connected with the outlet pipe 7.
[0018] The inlet casing 15 guides the gas into the rotor 16. The driving motor 1 is accelerated in speed by the gear box 14, and the rotor 16 is driven to work. Finally, the gas enters the volute 4 to be decelerated and expanded. The cooling system 8 cools the overheated steam at the outlet of the compressor to the saturated state to improve the steam heat exchange efficiency. The anti-surge valve 10 cooperates with the inlet flowmeter 18 to control the running state of the compressor. When the inlet flow of the compressor approaches the surge condition, the anti-surge valve 10 is opened to increase the inlet volume flow, so that the compressor is separated from the surge condition.

The carbon ring sealing is easy to wear and tear, and is not suitable for the scene of sealing toxic, flammable and explosive medium such as acetone. The sealing effect and service life of the dry gas seal 17 of the technical solution are superior to those of the carbon ring sealing. In addition, the anti-surge control of the water vapor compressor in the industry basically adopts motor current and power fluctuation to realize surge detection. The combination of the import flow meter 18 and the anti-surge valve 10 of the technical solution is more direct and accurate for detecting the surge condition. Compared with the screw type vapor compressor, the acetone vapor compressor of the technical solution is a single-stage centrifugal vapor compressor, and the working flow is larger. Compared with the multi-stage centrifugal compressor, the structure of the head 3 of the acetone vapor compressor of the technical solution is simpler.
