The invention discloses an efficient drying system utilizing a combination of solar energy and geothermal energy. The efficient drying system comprises the following three parts: a geothermal source heating device, a solar energy heating device and a drying device, wherein the geothermal source heating device, the solar energy heating device and the drying device are connected with one another through pipelines filled with a thermal change medium, so as to form three closed loops and meet the requirements for different heating and thermal storage modes of the efficient drying system; the threeclosed loops are connected to form a system; and through the regulation of change-over pumps, the geothermal source heating device or the solar energy heating device is selected for heating the drying device. By adoption of the efficient drying system provided by the invention, the problem that the mineral drying requirements cannot be met by utilizing the hot dry rock as a thermal source of a drying system can be solved through the combination of solar energy and geothermal energy. Furthermore, the problems that in the prior art, the utilization efficiency of geothermal energy in a mineral area is not high, several pollutants are extracted during the extraction of geothermal water, surface water or underground water is polluted, and the extraction and maintenance cost is relatively highcan be solved.
Description
technical field [0001] The invention relates to the technical field of geothermal utilization, in particular to an efficient drying system for combined utilization of solar energy and geothermal energy. Background technique [0002] There are obvious geothermal anomalies in the mining area, with an average geothermal gradient of 6°C / 100 meters. During the exploration, multiple boreholes were constructed with a depth of 1500-2000 meters. The measured temperature of the hot dry rock at the bottom of the hole is 105-135°C. Therefore, in order to reduce energy consumption when mineral products need to be dried, researchers use some hot dry rocks from exploration holes as the heat source for the drying system. At present, the use of geothermal energy in mining areas is usually to inject cold water into boreholes with hot dry rocks. After the heat exchange between the cold water and the hot dry rocks, it becomes hot water, which is pumped back into the system for heat exchange and...
