Description

Technical Field

[0001] The present invention relates to the technical field of steam residual pressure power generation, and in particular to a steam residual pressure power generation device which is convenient for adjusting steam pressure. Background Art

[0002] Steam is widely used as the main energy transfer medium. However, due to factors such as poor steam system design and changes in user-side parameters, there are a lot of problems between the supply and the user, such as mismatched steam pressure levels, mismatched steam production and usage, and low steam quality. As a result, a large amount of steam is used at reduced pressure or directly discharged during production and life, resulting in huge waste.

[0003] The excess pressure power generation system can efficiently recover a large amount of energy lost during pressure regulation, convert it into mechanical energy, and then use it for power generation. However, conventional excess pressure power generation systems often cannot respond to the different pressure requirements of different industrial users.

[0004] For example, a pressure regulating system based on steam residual pressure power generation disclosed in announcement number CN210567534U ensures that no water droplets enter the system through a steam-water separator, thereby preventing water droplets from damaging the turbine expander blades; monitors whether the pressure exceeds the critical value through the expander inlet pressure measuring point, and adjusts the pressure in conjunction with the expander inlet regulating valve, thereby preventing excessive water vapor pressure from entering the turbine expander; monitors the outlet pressure of the turbine expander through the expander outlet pressure measuring point, and adjusts the pressure to the user's required pressure in conjunction with the expander outlet regulating valve; prevents the backflow of high-pressure steam outside the system through a check valve; since different pressure differences will result in different speeds of the turbine expander, the internal transformation ratio of the grid-connected cabinet is adjusted by tracking the turbine speed to reduce the high-frequency AC power output by the generator to a frequency that meets user requirements.

[0005] However, the device is unable to process impurities in the steam during use, causing impurities to enter the expander pipeline and block the pipeline, thereby causing excessive pressure inside the pipeline, causing the pipeline to crack and causing safety problems. Summary of the invention
