Problems solved by technology

However, the existing oil and gas separators have disadvantages such as poor oil separation effect, low oil separation efficiency, and large pressure loss, which directly affect the performance of the working fluid and indirectly affect the efficiency of ORC waste heat power generation.
[0004] In order to solve the shortcomings of low oil separation efficiency, poor effect, and large pressure loss existing in existing oil-gas separation devices, the present invention has developed a screw expander oil-gas separation device for ORC waste heat power generation

Abstract

The invention discloses an oil-gas separation device of a screw expander, and relates to the screw expander. The oil-gas separation device of the screw expander comprises a tank; an oil storage bag isfixed at the bottom of the tank; a blade separator is fixed in the tank; the oil storage bag is provided with an oil outlet, and a seal is arranged at the bottom; the blade separator comprises bladesand an oil guide tank fixed on a frame; the frame and the tank are welded in a Z form; an oil return hole is formed in the tank on the lowermost side of the frame below an oil level; an oil viewing mirror is arranged on the outer wall of the tank, a pressure gauge and a safety valve are arranged at the top, and a thermal resistor is mounted on the lower side; an oil-gas inlet is formed in the side wall of the middle part of the tank; a liquid inlet pipe communicates into the tank from the oil-gas inlet, and the tail end is corresponding to the center of the seal of the tank; a flow separatoris arranged in the center position of the seal; an exhaust port is formed in the top of the tank; an exhaust pipe communicates into the tank from the exhaust port; and the tail end is positioned on aseal on the other side of the tank. The oil-gas separation device of the screw expander is compact in structure, easy to install, stable in performance and excellent in oil separation effect, and canbe widely applied to an oil-gas separation system of the screw expander for ORC afterheat power generation.

Description

technical field [0001] The invention relates to a screw expander, in particular to a screw expander oil-gas separation device for ORC waste heat power generation. Background technique [0002] Organic Rankine double cycle (ORC) technology is adopted, and the corresponding organic liquid working medium is selected to absorb low-temperature waste heat, generate high-pressure organic working medium steam, and drive the generator to generate electricity through the screw expander. This technology can be widely used in the recovery of heat sources such as by-product steam, hot water, flue gas, geothermal heat, solar energy, and biomass generated in industrial production. It can also be used as an alternative process for cooling and decompression processes, which is very important for energy saving and environmental protection. Significance. [0003] The working mechanism of the screw expander is to use the high-pressure gas to expand and reduce the pressure, output mechanical wo...
