The reaction gas and the reaction liquid react to generate the gas hydrate, which requires a low-temperature and high-pressure environment. The artificial synthesis of gas hydrate is generally carried out in a reaction kettle, and the existing hydrate generation reaction kettle has the forms of magnetic stirring, spiral stirring, bubbling and the like. However, the hydrates formed in the reaction vessel are often in the form of a hydrate slurry or a loose hydrate, which, after removal from the reaction vessel, requires compaction in special compaction equipment.
Chinese patent 201811521133.8 discloses a granulation apparatus for continuously preparing hydrate, which uses the reciprocating motion of three magnetic pistons to complete the generation and compaction of hydrate in the same apparatus, avoiding the need of special hydrate compaction equipment.
