Embodiment Construction

[0028] The present invention will be further described below in combination with specific embodiments.

[0029] Geothermal power generation device of the present invention, such as figure 1 Said, including production well 1, stop valve 2, regulating valve 3, steam-water separator 4, back pressure steam turbine 5, back pressure generator 6, vapor-liquid evaporator 7, liquid-liquid evaporator 8, preheater 9, Gas tank 10, booster pump 11, organic working medium steam turbine 12, generator 13, regenerator 14, condenser 15, working medium pump 16, recharge well 17, cooling pump 18, cooling tower 19.

[0030] The working process of this device is introduced as follows:

[0031] The geothermal water from the production well 1 passes through the shut-off valve 2, the pressure of the geothermal water drops, and then enters the steam-water separator 4 through the regulating valve 3, and the steam-water separator 4 separates the liquid and saturated gas in the geothermal fluid, and the ...

Abstract

The invention discloses a geothermal power generation device. Compared with the traditional geothermal power generation device, a heat exchange device is added: a regenerator and a gas-liquid evaporator, and a back pressure steam turbine and an organic working substance steam turbine are combined to make full use of the geothermal water. Although the initial investment increases, the power generation increases, the annual rate of return increases, the useful work of the system increases, and the total system loss decreases, so the thermal economy and efficiency of the device are improved. The invention also discloses a real-time monitoring system, which monitors the temperature, pressure, flow rate, etc. of each location of the above-mentioned geothermal power generation device, so as to timely find the pressure, flow rate and temperature imbalance problem, and prevent the equipment and pipelines of the power generation device from scaling.

Description

technical field [0001] The invention relates to the technical field of geothermal power generation, in particular to a geothermal power generation device and a real-time monitoring system thereof. Background technique [0002] Geothermal power generation has a relatively high utilization factor, with an average of 0.72 (72% of the time is working in a year). The higher the temperature of geothermal resources, the higher the efficiency of power generation and the better the economy. The investment cost of geothermal power generation includes power station equipment, geothermal wells and geothermal fluid transportation. Due to the uneven distribution of geothermal resources, drilling risks are high, and the initial investment of geothermal power generation is relatively high. However, geothermal resources are not affected by weather, day and night, and seasons, and can continuously and stably output high-quality electric energy, which has obvious competitiveness. With the sho...
