Horizontal geothermal extraction test system

Abstract

The invention discloses a horizontal geothermal extraction test system. The system comprises a heat source device, a high-temperature control device, a low-temperature control device, an acoustic emission acquisition device and a horizontal buried pipe simulation device; a water heating heat source is provided by the heat source device, water is heated by a heating water tank and then is connected into a test sleeve in the horizontal buried pipe simulation device, and the horizontal buried pipe simulation device is further provided with the high-temperature control device and the low-temperature control device which are used for controlling the influence of an external temperature environment on the ground and a backfill material thereof; and an acoustic emission receiver is further attached to a water circulation pipeline and used for collecting flowing sound of fluid in the pipeline, a plurality of temperature and humidity sensors are arranged, and multi-dimensional data collection is carried out according to collection and testing requirements. The system is further provided with a control terminal, the control terminal obtains sound data of the temperature sensors arranged at all the points to be tested and fluid flow for test analysis, and data of floor heating test are more comprehensive and effective.

Description

technical field [0001] The invention relates to geothermal energy utilization technology, in particular to a horizontal geothermal extraction test system. Background technique [0002] Geothermal energy is a green, low-carbon, recyclable and renewable energy. It has the characteristics of large reserves, wide distribution, cleanness, environmental protection, stability and reliability. It is a feasible and competitive clean energy. Accelerating the development and utilization of geothermal energy is not only of great significance to the adjustment of energy structure, energy conservation and emission reduction, and improvement of the environment, but also an important measure to promote the construction of ecological civilization. [0003] Ground source heat pump is a typical facility for geothermal energy utilization, often used in heating and cooling of public buildings and residential buildings. However, since ground source heat pumps were introduced into China, although...
