Ducted shaftless power generation device

Abstract

The invention discloses a ducted shaftless power generation device and relates to the field of power generation. A technical problem is solved by providing the ducted shaftless power generation devicecapable of using pressure difference during natural gas production and transportation to generate power. An adopted technical scheme is that the ducted shaftless power generation device comprises a gas inlet pipeline, a throttle valve, a pressure difference power generation system and a gas exhaust pipeline; the throttle valve and the pressure difference power generation system are connected between the gas inlet pipeline and the gas exhaust pipeline in series; the pressure difference power generation system comprises a stator and a rotor; the two ends of the stator are correspondingly sealedby using cover plates; the two cover plates are correspondingly a gas inlet end and a gas exhaust end of the power generation system; a stator coil is arranged in the stator; the internal side of thestator is connected with the rotor through a rotating piece; a rotor magnet is arranged in the rotor; an impeller is arranged on the internal side of the rotor; and the impeller is fixedly mounted onthe internal side of the rotor. As the middle part of the stator and the middle part of the rotor are shaftless, a gas flow passage is smooth, the resistance of the gas flow passage is small, and maximized energy conversion is realized. As the heat generated by the pressure difference power generation system is brought away with gas, a high temperature phenomenon is avoided.

Description

technical field [0001] The invention relates to the field of power generation, in particular to a device for generating power through an airflow with a pressure difference. Background technique [0002] During the production and transportation of natural gas, there is a flow pressure difference between the high-pressure wellhead of natural gas and the pressure of the gas pipeline. The authorized announcement number is CN 103334891 B, and the patent announced on August 26, 2015 discloses a power generation device that utilizes natural gas flowing pressure difference kinetic energy to generate electricity. The power generation device includes a main pipeline, an inlet pressure regulating valve, an outlet pressure regulating valve and a differential pressure power generation system, and the inlet pressure regulating valve, the differential pressure power generation system and the outlet pressure regulating valve are sequentially arranged in series on the main pipeline.
