Heat transfer device for geothermal energy double-circulation power generation

Abstract

The invention relates to the technical field of geothermal energy power generation and heat utilization engineering construction, and discloses a heat transfer device for geothermal energy double-circulation power generation, which comprises a heat transfer outer cylinder, the outer surface of the heat transfer outer cylinder is communicated with two transmission pipelines, a circular partition plate is arranged in the heat transfer outer cylinder, and four heat transfer inner cylinders are arranged in the circular partition plate. According to the heat transfer device for the geothermal energy double-circulation power generation provided by the invention, a large amount of heat generated by geothermal water is utilized, so that a heat-sensitive elastic plate is elastically deformed, the heat-sensitive elastic plate can push and extrude a pushing cleaning mechanism under the action of a supporting mechanism, and arc-shaped beating rods on the two sides can instantly rotate due to extrusion and pushing of the pushing cleaning mechanism, therefore, scale and impurities on the inner wall of the heat transfer inner cylinder are knocked and cleaned through triangular portions of triangular cone plates, and the situation that conveying of the geothermal water is affected due to the fact that too much scale and impurities are condensed in the heat transfer inner cylinder is prevented.

Description

technical field [0001] The invention relates to the technical field of geothermal energy power generation and heat utilization engineering construction, in particular to a heat transfer device for geothermal energy double-cycle power generation. Background technique [0002] The process of the double circulation system: the geothermal water first flows through the heat exchanger, and the geothermal energy is transferred to another low-boiling working fluid to make it boil to generate steam. The steam enters the steam turbine to do work and enters the condenser, and then passes exchanger to complete the power generation cycle. Geothermal water is injected back into the formation from the heat exchanger. [0003] When exchanging heat for fluids with different boiling points, due to heat changes inside the flow channel, the saturated substances in the fluid will crystallize, and the crystallized substances will remain on the inner wall of the flow channel. If these crystals ar...

[0003] When exchanging heat for fluids with different boiling points, due to the heat change inside the flow channel, the saturated substances in the fluid will crystallize, and the crystallized substances will remain on the inner wall of the flow channel. If these crystals are not treated Timely cleaning will seriously affect the flow of fluid
