Embodiment Construction

[0013] As shown in the accompanying drawings, the present invention includes: geothermal fluid, heat pipe, heat exchange box, steam conduit, steam turbine, generator, low boiling point working medium; geothermal fluid provides heat energy for the entire power generation device, by heating the collector end of the heat pipe, Using the principle of heat pipe heat conduction, the heat is exported to the heat dissipation end. The heat dissipation end is located in the heat exchange box. The inside of the heat exchange box is filled with low-boiling point refrigerant. After being heated by the heat dissipation end as a secondary heat source, the low-boiling point refrigerant is converted into a steam state. The steam pipe enters the steam turbine, drives the steam turbine to do work and rotate, and converts heat energy into mechanical energy. The steam turbine is coaxial with the generator, and then converts mechanical energy into electrical energy for output.

Abstract

The invention relates to a geothermal generating set, which comprises a geothermal fluid, wherein the geothermal fluid is connected with a heat exchange box through a heat pipe, and a steam guide pipe is arranged at one end of the heat exchange box and is connected with a turbine; and the turbine is also connected with a generator, and a low-boiling-point refrigerant is arranged in the heat exchange box and adopts chloroethane, n-butane, isobutane and other fluoride-free refrigerants. The geothermal fluid supplies heat energy to the whole set of power generating device, and the heat is leaded out to a heat dissipation end by heating the heat collecting end of a heat pipe; the heat dissipation end is positioned in the heat exchange box, and the low-boiling-point refrigerant is filled inside the heat exchange box and is used as a secondary heat source to heat the heat dissipation end; the low-boiling-point refrigerant is converted into a steam state to enter the turbine through the steam guide pipe, so that the turbine is driven to do work and rotate to convert heat energy into mechanical energy; the turbine and the generator are coaxial, and thus the mechanical energy is converted into electrical energy to be output; and the heat energy utilization rate is high, and the energy transfer process is pure. The geothermal generating set has a good practical application value.

Description

technical field [0001] The invention relates to a geothermal power generation device, which provides an environment-friendly and high-efficiency thermoelectric conversion device for areas with natural geothermal heat. Background technique [0002] With the shortage of fossil energy and the increase of environmental pressure, people pay more and more attention to clearing up renewable green energy. Geothermal energy has been used by humans a long time ago. Most of the geothermal power generation methods adopted by countries around the world are direct Steam power generation method, the device of this method is the most simple and easy to implement, but it also has its disadvantages: low heat utilization efficiency, high requirements for underground heat sources, and it is not easy to directly mine steam energy, etc. Therefore, the traditional geothermal power generation system should be carried out Transformation to make it more suitable for geographical environment and artif...
