A device and a method for drawing high-temperature geothermal heat to generate power utilize liquid-vapor phase change to continuously transmit high-temperature geothermal heat to the ground to generate power. The power-generating device comprises an evaporator (1), a condenser (2), an exhaust valve (21), an electric air valve (18), a steam pipe (19) having the electric air valve (18), an electric throttle valve (23), a main reflux pipe (22) having the electric throttle valve (23), an inner reflux pipe (24) capable of generating swirl, and a steam turbine set (7).The evaporator (1) is arranged in an underground high-temperature geothermal region, and the working medium used inside the power-generating device has a high heat transfer coefficient. The inner reflux pipe (24) capable of generating swirl enables the two-phase flow working medium in a cavity of the evaporator (1) to generate rotation. The power-generating device can work efficiently, safely, and reliably at a high temperature. |
