Deep well heat exchange sleeve geothermal in-situ thermovoltaic power generation device

Abstract

The invention discloses a deep well heat exchange sleeve geothermal in-situ thermovoltaic power generation device, and relates to the field of geothermal power generation. The device is composed of awater inlet section, a reverser, a sleeve heat exchange section, a top thermovoltaic power generation module and a turbine power generation module. The water inlet section, the reverser and the sleeveheat exchange section are all arranged underground and are in butt joint in sequence from deep ground to the ground surface; and the top thermovoltaic power generation module is partially installed underground and partially installed on the ground, and the turbine power generation module is installed on the ground. According to the device, two power generation manners of the top thermovoltaic power generation module and a turbine generator are adopted. Electric energy of the turbine generator is directly output as a turbine power generation power supply, power supplies of pipe wall type thermovoltaic power generation basic modules are output in parallel, and an output power supply is called as a pipe wall thermovoltaic power supply. The device meets the deep land in-situ geothermal powergeneration requirement required by construction, geothermal water is recharged in situ in the in-situ geothermal power generation process, and the recharging water level is far lower than the hot water taking level; and two power generation technologies are adopted to improve the power generation efficiency.

Description

[0001] 1. Technical field [0002] The invention relates to the field of geothermal power generation, in particular to a deep well heat exchange sleeve geothermal in-situ thermal photovoltaic power generation device. [0003] 2. Background technology [0004] Geothermal is a new type of clean energy, widely distributed and rich in reserves. Using geothermal energy for power generation and heat extraction produces little pollution and renewable energy, and the unit cost of power generation and heat extraction is low. Therefore, geothermal power generation and heat extraction are receiving more and more attention and utilization. Application number CN202010112988.6 "An In-Situ Geothermal Power Generation System" provides an in-situ geothermal power generation system, including heat pipes, thermoelectric thermoelectric power generation devices and magnetic levitation power generation devices. The heat pipe is directly buried deep in the ground, and the heat pipe is located at th...
