Gas hydrate preparation system

Abstract

The invention belongs to the technical field of hydrate preparation, and particularly relates to a gas hydrate preparation system. According to the system, a gas microplate arranged in a gas-liquid premixer disperses gas into small particle sizes, the dispersed gas is mixed with liquid, then a formed mixture is uniformly dispersed, and a mixing degree is improved through a narrow flow channel; when the premixed materials enter a hydrate reactor for a reaction, the stirring of horizontal hollow double shafts further promotes sufficient gas-liquid mixing and accelerates reaction process; cleaning paddles can effectively prevent blocking caused by adhesion of hydrates on a wall surface and stirring shafts, and the hydrate reactor can automatically monitor reaction pressure and perform automatic gas supply or pressure relief to maintain a constant pressure required by the reaction; a temperature sensor group monitors and feeds back a material temperature to the refrigeration system of an all-in-one machine to keep the temperature constant, heat exchange effect is good, and reaction heat can be effectively taken away; and a detection point is located at the bottom end of the reaction cavity, and use requirements of laboratories and industrial production can be met at the same time.

Description

Technical field: [0001] The invention belongs to the technical field of hydrate preparation, and in particular relates to a gas hydrate preparation system capable of efficiently and continuously preparing hydrate. Background technique: [0002] After a long period of exploration and development, hydrate research has formed a science with great industrial application prospects. Hydrates are widely used: the decomposition and generation technology of hydrates can effectively solve the problems of gas transportation and storage, liquid concentration and separation, seawater desalination, sewage treatment, refrigeration and cold storage. The fundamental reasons hindering the development of hydrate technology are: harsh formation conditions, slow growth rate and difficulty in realizing large-scale industrial production. [0003] When specific environmental conditions are met, hydrates nucleate at the interface between water droplets and guest molecules, and quickly form hydrate ...
