Abstract

The invention discloses an open system chemical kinetics high-temperature and high-pressure experimental device which comprises a cold-seal type tubular high-pressure kettle, a temperature control furnace, a pressurization system, an online feed device, an online sampling device, a multi-parameter detector and a computer, wherein the cold-seal type tubular high-pressure kettle is buried in the temperature control furnace and comprises a tubular kettle body with a closed lower end and a kettle cover in threaded connection with the tubular kettle body; an output port of the pressurization systemis communicated with the cold-seal type tubular high-pressure kettle; the online feed device and the online sampling device are communicated with the top and bottom of the cold-seal type tubular high-pressure kettle; a probe of the multi-parameter detector extends into a sampling bottle of the online sampling device to perform online detection; the computer is in signal connection with the multi-parameter detector; a thermocouple of the cold-seal type tubular high-pressure kettle and the temperature control furnace are connected with a temperature controller. According to the open system chemical kinetics high-temperature and high-pressure experimental device disclosed by the invention, the high-pressure kettle is connected with online feed and discharge devices and the multi-parameter detector; a sample in the kettle is in an open flowing state during an experiment, thus, dynamic processes during element migration, hydrolysis and water-rock interaction can be detected.

Description

technical field [0001] The invention belongs to the technical field of experimental equipment, and in particular relates to an open system chemical dynamics high temperature and high pressure experimental device which is safe, reliable, resistant to high temperature and high pressure, capable of simulating the chemical kinetic process of an open system, and capable of online sample feeding and sampling. Background technique [0002] The activation, migration, and precipitation of substances in hydrothermal fluids are very important ore-forming geological processes in nature. For a long time, people have carried out theoretical and experimental research on the phase equilibrium relationship from the perspective of thermodynamics, and completed many theories in traditional geosciences. Although these achievements are helpful for understanding and deepening mineralization, they still have great limitations. There is still a big gap between the steady-state model that achieves e...
