Intelligent control high-temperature rock-low-temperature water heat exchange device and using method

Abstract

The invention discloses an intelligent control high-temperature rock-low-temperature water heat exchange device and a use method. The intelligent control high-temperature rock-low-temperature water heat exchange device mainly comprises a water temperature controller, a constant-speed water pump, an annular rock sample heater, a high-temperature rock sample placement cabin, a water storage cabin, a water return pump, an intelligent analysis operation table and other auxiliary devices. And a temperature control system is arranged in the water temperature controller. And a flow speed controller is arranged in the constant-speed water pump. And a heating system is arranged in the annular rock sample heater. And intelligent cabin door switching devices are arranged on two sides of the high-temperature rock sample placing cabin. A water pipe external connector is arranged outside the water storage bin. And an intelligent sensor is arranged in the water return pump. The system is simple in structure, the rock temperature, the water temperature and the flow speed are efficiently, safely and innovatively adjusted through an intelligent analysis control system, and the safety of workers is guaranteed while the labor cost and the engineering operation time are saved; water can be recycled through cooperation of the mechanisms, the purpose of saving water is achieved, and the requirement for heat exchange accuracy of low-temperature water passing through a high-temperature rock sample is met.

Description

technical field [0001] The invention belongs to the technical field of deep high temperature rock mechanics, in particular to an intelligently controlled high temperature rock-low temperature water heat exchange device and a use method. Background technique [0002] The realization technology of rock-water heat exchange has a profound impact on the exploitation of deep geothermal resources, and the laboratory experiments after simulating deep rock-water heat exchange are inseparable from this technology. At this stage, the engineering operations to realize rock-water heat exchange mainly have the following shortcomings and difficulties: 1. The flow rate and temperature of water during the heat exchange process cannot be controlled; 2. When the high-temperature rock sample exchanges heat with low-temperature water, the exposed The surface of the rock sample is prone to safety accidents; 3. The sealing between the end of the rock sample and the water pipe during heat exchange ...
