Abstract

The invention relates to a teaching device for demonstrating a gas hydrate formation and decomposition process. The device comprises a high-pressure reaction kettle with a transparent window, a pressure adjusting assembly, a temperature adjusting assembly, a computer control assembly and a projection assembly; the pressure adjusting assembly comprises a volume-variable gas cylinder and a servo motor; the volume-variable gas cylinder is used for pressing gas into the high-pressure reaction kettle or drawing the gas out of the high-pressure reaction kettle; the servo motor is used for controlling the movement of the volume-variable gas cylinder; the temperature adjusting assembly is used for adjusting the temperature of the high-pressure reaction kettle and the volume-variable gas cylinder;the computer control assembly is used for receiving temperature and pressure signals of the volume-variable gas cylinder and controlling the servo motor to be turned on or turned off; the projection assembly is used for displaying a phase change balance curve and the temperature and pressure of the high-pressure reaction kettle. The teaching device has high safety factor and visual display performance, and the temperature and pressure conditions and macroscopic morphology of the formation and decomposition of a gas hydrate can be clearly displayed.

Description

technical field [0001] The invention relates to the technical field of gas hydrates, in particular to a teaching device for demonstrating the formation and decomposition process of gas hydrates. Background technique [0002] Gas hydrate is a crystalline substance produced by natural gas and water under high pressure and low temperature conditions, and is mainly distributed in seabed sediments and some terrestrial permafrost zones. Gas hydrate is widely distributed and has high energy density. Its organic carbon content is twice the total carbon content of coal, oil, and natural gas. With the application of gas hydrate technology in natural gas exploration and development, oil and gas pipeline transportation, bioengineering and environmental protection, research on gas hydrate has attracted increasing attention. [0003] At present, in the teaching related to gas storage, transportation and utilization, the teaching content mainly involves pipeline transportation and high-pr...
