Abstract

The invention relates to the field of geothermal tail water recharge, in particular to an indoor simulation soil column experiment device under a geothermal tail water sandstone recharge condition. The device comprises a water supply structure, a soil column pipe and a solution collection structure; the soil column pipe is connected with the water supply structure and the solution collection structure, and a constant temperature water bath structure is arranged on the outer circumference of the soil column pipe. The constant temperature water bath structure is used for keeping the temperatureof the soil column pipe within a set range; a pressure measuring hole and a sampling port are formed in the soil column pipe at intervals, the pressure measuring hole is connected with a pressure measuring structure used for measuring water pressure, the sampling port is connected with a sampler, and the sampling port is communicated with an inner cavity of the soil column pipe. The invention hasthe beneficial effects that the overall structure is simple, and sampling is convenient; and the arranged constant-temperature water bath structure simulates the temperature environment under the geothermal tail water sandstone recharge condition, condition parameters for simulating a soil column experiment are increased, and the experiment is more real and accurate.

Description

technical field [0001] The invention relates to the field of geothermal tail water recharge, in particular to an indoor simulated soil column experimental device under the condition of geothermal tail water sandstone recharge. Background technique [0002] Geothermal resource is a clean and renewable energy with large reserves, high efficiency and good stability, which is of great significance for energy saving and emission reduction, coping with global warming and controlling smog. However, with the continuous development of geothermal resources, the groundwater level in some areas has shown an obvious downward trend, seriously affecting the supply of local water resources and restricting the further exploitation of hydrothermal resources. The recharge problem of carbonatite thermal storage has been basically solved, while the low recharge rate of sandstone thermal storage has become a bottleneck for the sustainable development and utilization of medium-low temperature geot...
