Device for rapidly and continuously preparing gas hydrate

Abstract

The invention discloses a device for rapidly and continuously preparing a gas hydrate. The device comprises a reactor with an outer water jacket, a gas supply unit for supplying a gas source to the reactor, an ice liquid supply unit for supplying an ice liquid to the reactor, a temperature control unit for controlling the temperature of the outer jacket, a hydrate filtering and collecting unit connected to the reactor and used for filtering and collecting produced hydrate crystals, and a data acquisition and processing unit for acquiring and recording the temperature and pressure data of the reactor. The rear end of the hydrate filtering and collecting unit is connected to the ice liquid supply unit through a quick-connecting valve. The device solves the problem that the conventional hydrate formation device has no a complete hydrate formation process, produces internal retention in the stirred slurry or on a magneton and has no a continuous reaction process. The experimental device issimple and economical, is easy to operate, produces a complete and uniform gas hydrate and improves the efficiency of gas storage and transportation.

Description

technical field [0001] The invention relates to experimental equipment for preparing gas hydrate, in particular to a device for rapidly and continuously preparing gas hydrate. Background technique [0002] Gas hydrate is an ice-like cage crystal compound formed by gas molecules (such as methane, carbon dioxide, nitrogen, hydrogen sulfide, etc.) and water molecules under low temperature and high pressure conditions. In recent years, with the deepening of gas hydrate research, it has been found that the use of gas hydrate for gas separation, storage and transportation can become a new and efficient industrial technology. [0003] In the research, it was found that stirring has a great influence on the kinetic properties of hydrate formation, especially the induction time and gas storage capacity. At present, the existing stirring technology is internal mechanical stirring or magnetic stirring. When stirring, a mechanical stirring paddle or magnet is placed inside the reactio...

AI Technical Summary

Problems solved by technology

These two methods have disadvantages: first, the formation of hydrate blocks at the air-water interface will hinder the continued formation of hydrates in the lower part, and the mechanical stirring blade or magnet will also be consolidated by the generated hydrate blocks, making it impossible to complete the stirring and mixing task ; Second, during the transportation process after the hydrate is formed, the mechanical stirring paddle or magnet is integrated with the hydrate and cannot be taken out; the third is that the hydrate cannot be continuously produced
