Steam pressure energy recovery system based on screw expansion power generation

The invention relates to the technical field of waste heat utilization, in particular to a steam pressure energy recovery system based on screw expansion power generation. The system is composed of a steam recovery unit, a screw expander, a generator set and a control module, and the steam recovery unit is used for collecting high-pressure steam generated in the industrial production process and conveying the high-pressure steam to the screw expander through a steam pipeline; the screw expander adopts a double-screw design, so that the pressure energy of high-pressure steam is converted into mechanical energy; the generator set is connected with the screw expander and converts mechanical energy generated by the screw expander into electric energy. And the control module adopts a control algorithm and a sensor technology to realize real-time monitoring and adjustment of the running state of the system. The invention provides a steam pressure energy recovery system based on screw expansion power generation. The
