Energy exchange device for geothermal power generation system

Abstract

The invention discloses an energy exchange device for a geothermal power generation system, and belongs to the field of geothermal power generation devices. According to the energy exchange device forthe geothermal power generation system, application of geothermal energy is realized through direct heat exchange, heat interaction is realized between geothermal steam and a heat exchange medium through a heat conduction net and heat conduction fiber clusters, due to the design of the heat conduction net and the heat conduction fiber clusters, the specific surface area of a heat conduction device can be greatly increased, the heat conduction efficiency is improved, namely the heat utilization rate of the geothermal steam is increased, by means of filling fibers on the surface of winding parts, on one hand, the connecting strength between the heat conduction fiber clusters and barbs can be improved, on the other hand, the connecting strength between the adjacent winding parts can be effectively improved, heat exchange can be conducted through the heat conduction device on the premise that the geothermal energy utilization rate is not affected, meanwhile, the situation that the heat conduction device is damaged by stone chips mixed in the steam is not likely to happen, and the service life of the heat conduction device is greatly prolonged.

Description

technical field [0001] The invention relates to the field of geothermal power generation devices, and more specifically, relates to an energy exchange device used in a geothermal power generation system. Background technique [0002] Geothermal energy is natural thermal energy extracted from the earth's crust. This energy comes from the lava inside the earth and exists in the form of heat. It is the energy that causes volcanic eruptions and earthquakes. Geothermal power generation is the most important way to utilize geothermal energy. High-temperature geothermal fluid should be firstly applied to power generation. The principle of geothermal power generation and thermal power generation is the same, both use the heat energy of steam to convert into mechanical energy in the steam turbine, and then drive the generator to generate electricity. The difference is that geothermal power generation does not need to be equipped with huge boilers like thermal power generation, nor d...

Problems solved by technology

[0004]Under normal circumstances, in order to increase the utilization efficiency of geothermal energy, the steam flow rising from the geothermal layer is usually not cleaned, and the steam is easy to be entrained in the process of rising If there are sundries such as stone chips, if the heat exchange between the local heat pipe and the steam pipe is carried out directly through heat conduction devices such as fins, these stone chips and other sundries can easily cause damage to the heat conduction device, and if non-contact heat exchange is used, it will It will affect the efficiency of human exchange and the utilization rate of geothermal energy
