Geothermal energy development and utilization circulating system with intelligent monitoring and descaling functions

Abstract

The invention discloses a geothermal energy development and utilization circulating system with intelligent monitoring and descaling functions. The geothermal energy development and utilization circulating system with the intelligent monitoring and descaling functions comprises a steam and water separator which is connected with a production well and used for carrying out steam and water separation on an input heat source carrier, and a solid detection and slag discharging device is arranged at the bottom of the steam and water separator. A heat exchanger is arranged on the lower portion of the steam and water separator. A plurality of high-temperature steam output ports communicate with the upper portion and the top of the steam and water separator, the output end of the heat exchanger and the output ends of the high-temperature steam are connected with a geothermal utilization subsystem, and condensate fluid of the geothermal utilization subsystem is connected to a water injection pipe and is injected into a water injection well through the water injection pipe to form water circulating utilization, and the water injection pipe is externally connected with water quality treatmentequipment to carry out softening treatment on the condensate fluid flowing through the water injection pipe. The system is reliable in running performance, stable and safe.

Description

technical field [0001] The invention relates to the technical field of geothermal energy mining and comprehensive utilization, in particular to a geothermal energy development and utilization cycle system with intelligent monitoring and descaling functions. Background technique [0002] Deep geothermal resources, especially the thermal energy mining application field of hot dry rock, because the thermal storage resources of this reservoir are relatively abundant, and many existing mining technologies are becoming more and more mature, it will be used as an alternative renewable clean energy development condition in the future energy market are available. The achievements of comprehensive development and utilization of geothermal energy in the world in recent decades are enough to prove that the large-scale exploitation and extensive comprehensive utilization of deep geothermal energy meet the conditions for sustainable development. [0003] However, in the geothermal utiliz...

Problems solved by technology

[0003] However, in the geothermal utilization system of the prior art, the composition of the heat source carrier extracted from the deep underground geothermal resources through the production well is relatively complicated, such as the heat source carrier often brings out more sediment and other solid impurities, etc. During the process, the sediment brought out by the heat source carrier often scales on the experienced equipment, and because the pH of the heat source carrier is not suitable, the demand for back-end heat cannot be met, etc.

In general, the geothermal utilization system of the prior art lacks "digestion" func
