Abstract

The invention provides a rapid synthesis device for natural gas hydrate. The rapid synthesis device comprises a gas supply pipeline, a liquid supply pipeline, a stirring device and a data acquisition control system. The gas supply pipeline is used for conveying gas in a gas cylinder into a reaction kettle and is communicated with a gas inlet a in the bottom of the reaction kettle through an outlet of the gas cylinder via a pipeline. The liquid supply pipeline is used for conveying water in a water tank into the reaction kettle and is communicated with a liquid phase inlet c of the reaction kettle through an outlet of the water tank via a pipeline, and a plunger pump is arranged on the communicating pipeline. The stirring device is formed by installing a stirrer in the reaction kettle, propeller blades are adopted for a stirring and smashing paddle of the stirrer, and a smashing tooth cone is installed below the blades. By means of the rapid synthesis device for natural gas hydrate, the synthesis efficiency of natural gas hydrate can be improved, and thus the industrialization process of natural gas hydrate is promoted.

Description

technical field [0001] The invention relates to the technical field of natural gas hydrate exploitation and utilization thereof, in particular to a natural gas hydrate rapid synthesis device. Background technique [0002] Natural gas hydrate is composed of small molecular hydrocarbons (mainly CH 4 ) and water molecules rely on van der Waals force to form a cage crystal substance under low temperature and high pressure conditions. Theoretically, 1m 3 The natural gas hydrate can release 164m 3 Standard state CH 4 and 0.8m 3 of water. The amount of methane stored in the global natural gas hydrate is about (1.8-2.1)x10 16 m 3 , equivalent to more than twice the fossil fuels such as coal, oil, and natural gas that have been found in the world. [0003] Due to the characteristics of wide distribution, large reserves, high energy density, green and clean, natural gas hydrate is considered to be a fourth-generation new alternative energy with great potential. Since the eigh...
