The invention relates to a rock high-temperature hydrolysis simulation device and a control method thereof. The rock high-temperature hydrolysis simulation device consists of a hydrolysis reaction kettle, a water inlet and storage system, an automatic control system and a safety device; the upper part of the hydrolysis reaction kettle is provided with a water spraying mechanism; the bottom is provided with a water and rock disintegrated particle collector; a heating device is arranged outside the hydrolysis reaction kettle; a temperature sensor is arranged in the hydrolysis reaction kettle, and the output of the temperature sensor is connected with the control system; the water inlet and storage system is provided with a water storage device and a water level sensor, and the output of the water inlet and storage system is connected with the control system; water feeding and water discharging of the water storage device are controlled through a water pump and an electromagnetic valve, the water in the water storage device can successfully enter the reaction kettle by isolating the internal air pressure and the external air pressure, and the discharged water is delivered to the upper part of the hydrolysis reaction kettle; a single chip microprocessor of the automatic control system is connected with a control computer; the device is provided with a safety valve. By simulating the hydrolysis reaction of the rock, and promoting the weathering and denudation speed, the content of each substance element and newly formed minerals of dissolved and rock disintegrated particles as well as relevant thermodynamics and dynamics processes are determined, so that the weathering mechanism of the rock can be convenient to research.
Description
technical field [0001] The invention relates to the research field of rock erosion and weathering in geology, in particular to a rock high-temperature hydrolysis simulation device. The invention also relates to a control method of the rock high temperature hydrolysis simulation device. Background technique [0002] Rock weathering is the most important and common geological process on the earth's surface. External factors that cause rock damage include temperature changes, dissolution of water and various acids, biological effects, and denudation of various geological forces. Rock weathering can be divided into physical decomposition, chemical decomposition and biological decomposition according to its nature. Rock hydrolysis is one of chemical weathering. Under the action of water, rock undergoes hydrolysis, which not only decomposes to produce new minerals, but also dissolves chlorine, sulfur, calcium, sodium, magnesium, potassium, silicon, iron, aluminum, Phosphorus et...
