[0001] This utility model relates to the field of steam turbine technology, and in particular to a high-efficiency steam turbine. Background Technology

[0002] Steam turbines, as efficient and multifunctional heat energy conversion devices, play a vital role in modern industry and daily life. They heat water to boiling point, generating high-temperature, high-pressure steam. This steam, due to its unique physical properties, is widely used in various fields such as high-temperature sterilization, kitchen cooking, washing and cleaning, and clothes drying. In high-temperature sterilization, the steam generated by steam turbines has powerful bactericidal capabilities, quickly and effectively killing bacteria, viruses, and other microorganisms, ensuring the safety and hygiene of food, medical devices, and other items. In the kitchen, steam cooking not only preserves the original flavor of ingredients but also makes food softer and more palatable, satisfying people's pursuit of healthy eating.

[0003] Traditional steam generators typically use electric heating, which is not only energy-intensive but also inefficient. Traditional electrically heated steam generators can no longer meet the energy-saving requirements of modern industry and daily life; therefore, a high-efficiency steam unit is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a high-efficiency steam turbine unit to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a high-efficiency steam turbine unit, including a first compressor and a second compressor. The output end of the first compressor is connected to a medium-temperature heat exchanger via a pipe. The first output end of the medium-temperature heat exchanger is connected to a first liquid receiver via a pipe. The output end of the first liquid receiver is connected to an economical heat exchanger via a pipe. The first output end of the economical heat exchanger is connected to a first electronic expansion valve via a pipe. The output end of the first electronic expansion valve is connected to a condenser via a pipe. The output end of the condenser is connected to the input end of the first compressor via a pipe. The input end of the second compressor is connected to the second output end of the medium-temperature heat exchanger via a pipe. The output end of the second compressor is connected to a high-temperature heat exchanger via a pipe. The output end of the high-temperature heat exchanger is connected to a second liquid receiver via a pipe. The output end of the second liquid receiver is connected to a second electronic expansion valve via a pipe. The output end of the second electronic expansion valve is connected to the second input end of the medium-temperature heat exchanger via a pipe.

[0007] Preferably, in any of the above schemes, the first input end of the medium-temperature heat exchanger is connected to the output end of the first compressor via a pipe.

[0008] Preferably, in any of the above schemes, the first input end of the economical heat exchanger is connected to the output end of the first liquid reservoir via a pipe.

[0011] Preferably, in any of the above solutions, a first filter is provided between the first liquid receiver and the economic heat exchanger, and a second filter is provided between the second liquid receiver and the second electronic expansion valve.

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

[0013] 1. When steam generation is required, the output of the first compressor generates high-temperature steam, which is then transported through a pipeline to the medium-temperature heat exchanger. After passing through the medium-temperature heat exchanger, the steam flows into the first liquid receiver and is recycled with the condenser through the first electronic expansion valve. The medium-temperature heat exchanger can increase the temperature of the liquid entering the second compressor. The liquid heated by the medium-temperature heat exchanger flows into the second compressor for compression, forming water vapor at an even higher temperature. This water vapor flows into the high-temperature heat exchanger to heat the water inside, heating it to boiling point and forming steam. The work done by the first and second compressors achieves the transfer of heat energy. Compared with electrically heated steam generators, this method has higher efficiency and can produce more steam while consuming the same amount of electrical energy.

[0014] 2. The input end of the first compressor is connected to the second output end of the economic heat exchanger via a pipeline, forming a closed-loop system. Simultaneously, the first output end of the economic heat exchanger is connected to a third electronic expansion valve via a pipeline, and the output end of the third electronic expansion valve is then connected to the second output end of the economic heat exchanger via a pipeline. This design enables precise control and regulation of the refrigerant, ensuring stable system operation under different operating conditions, while simultaneously improving the system's energy efficiency ratio.

[0020] As an optional technical solution of this utility model, the first input end of the medium-temperature heat exchanger 3 is connected to the output end of the first compressor 1 through a pipe. This design allows the high-temperature and high-pressure steam to directly enter the medium-temperature heat exchanger 3 for heat exchange after being output from the first compressor 1, which improves thermal efficiency and makes the entire steam unit's workflow more compact and efficient.

[0021] As an optional technical solution of this utility model, the first input end of the economic heat exchanger 5 is connected to the output end of the first liquid reservoir 4 through a pipe. This design can make full use of the liquid refrigerant stored in the first liquid reservoir 4, and further heat exchange through the economic heat exchanger 5, thereby improving the energy recovery and utilization efficiency and reducing energy consumption.

[0022] As an optional technical solution of this utility model, the input end of the first compressor 1 is connected to the second output end of the economic heat exchanger 5 via a pipe. The first output end of the economic heat exchanger 5 is connected to a third electronic expansion valve 11 via a pipe, and the output end of the third electronic expansion valve 11 is connected to the second output end of the economic heat exchanger 5 via a pipe.

[0025] A high-efficiency steam turbine unit operates on the following principle:

[0026] 1): When steam generation is required, the output of the first compressor 1 generates high-temperature steam and delivers it to the medium-temperature heat exchanger 3 through a pipeline. After passing through the medium-temperature heat exchanger 3, it flows into the first liquid receiver 4 and is recycled with the condenser 7 through the first electronic expansion valve 6.

[0027] 2): The temperature of the liquid entering the second compressor 2 can be increased by the medium-temperature heat exchanger 3. The liquid heated by the medium-temperature heat exchanger 3 flows into the second compressor 2 for compression, forming water vapor at a higher temperature.

[0028] 3): This part of the water vapor flows into the high-temperature heat exchanger 8 and can heat the water inside it. After being heated to boiling, it forms water vapor, which is then used to transfer heat energy through the work of the first compressor 1 and the second compressor 2.

[0029] In summary, this high-efficiency steam generator unit, when steam generation is required, generates high-temperature steam at the output of the first compressor 1 and transports it through a pipeline to the medium-temperature heat exchanger 3. After flowing through the medium-temperature heat exchanger 3, it flows into the first liquid receiver 4 and is recycled through the first electronic expansion valve 6 and the condenser 7. The medium-temperature heat exchanger 3 can increase the temperature of the liquid entering the second compressor 2. The liquid heated by the medium-temperature heat exchanger 3 flows into the second compressor 2 for compression, forming water vapor at an even higher temperature. This water vapor flows into the high-temperature heat exchanger 8 and heats the water inside until it boils, forming steam. The work done by the first compressor 1 and the second compressor 2 achieves the transfer of heat energy. Compared with an electrically heated steam generator, it has higher efficiency and can produce more steam with the same amount of electrical energy consumed.
