System for researching form of hanging water drop gas hydrate

Abstract

The invention relates to a suspending drop gas hydrate generation research system which comprises a reaction vessel, a gas supply system, a temperature control system, a drop control system and a data acquisition system. The end of the reaction vessel is provided with pressure withstand optical glass having a visualization function and the reaction vessel is sheathed in a cooling jacket which keeps a constant temperature through the temperature control system; a gas inlet on the reaction vessel is communicated with the gas supply system, the suspending orifice of the reaction vessel is communicated with the drop control system and a temperature sensor and a pressure sensor on the reaction vessel are externally connected with the data acquisition system. The research device is pressure resistant and convenient to operate, monitor and observe experimental phenomena, has a visual microscopic function and can carry out the morphological study of hydrates generated by drop, phase equilibrium characteristics study, dynamic characteristics study of hydrates generated by drop under constant temperature or constant pressure condition, etc.

Description

technical field

[0001] The invention relates to a device for preparing and researching gas hydrates, in particular to a system for researching the formation of gas hydrates in pendant water droplets with a visualized microscopic function. Background technique

[0002] Gas hydrate is a kind of water and small molecular gas (CH 4 、C 2 h 6 , CO 2 etc.) to form cage-like crystals, and different types of gases form different types of gas hydrates. There are three types of hydrate crystal structures discovered, namely type I, type II and type H. Type I and Type II hydrates are two common structures in nature and industrial processes, including large and small crystal cavities, and H-type hydrates include large, medium and small crystal cavities. Gas hydrate has the advantages of low density, low thermal conductivity, small specific heat capacity, stable thermophysical properties, high gas storage density, easy preparation conditions, and simple regasification technology.
