Abstract

The invention discloses a fast preparation method and apparatus of natural gas hydrate with static supergravity, which is characterized that: a reactor is connected with an air intake route, a water inlet route and a vomit route; the air intake route and the water inlet route are all provided with compression device; the air intake route is provided with a spout; the water inlet rout is provided with a nozzle; the spout and the spout are all arranged in the reactor; the spout is arranged on the inner wall of the reactor and to the circumferential direction; the nozzle is arranged on the axial position of the upper part in the reactor; an inner cooler is arranged on the axial position of the reactor and an air vent is arranged on the upper part of the reactor. The apparatus can not only remove the hydration heat fast, but also can change the flow field of gas, liquid and solid in the reactor, so as to realize the fast renewal of the three-phase interface of gas, liquid and solid.

Description

technical field [0001] The invention relates to natural gas hydrate, in particular to a method and device for rapidly preparing natural gas hydrate by using static supergravity. Background technique [0002] The existing natural gas hydrate storage and transportation technology is a new technology researched and developed abroad in recent years. A unit volume of hydrate can safely store 150 to 200 times the volume of natural gas; because hydrate has a "self-protection effect", natural gas The large-scale storage and transportation of hydrates under normal pressure does not need to be cooled below the phase equilibrium temperature, but the hydrates should be frozen below the freezing point of water (-15 ~ +5 โ„ƒ). If the heat preservation is good, the hydrates can remain stable with almost no Natural gas leaks; in addition, natural gas hydrate is very safe, even if it is ignited by an open flame, it burns slowly; compared with pipeline natural gas transportation or liquefied na...
