Abstract

The invention discloses a visualization device for preparing gas hydrate in a spraying way, which comprises a gas circulating loop, a reaction water circulating loop, a cooling medium liquid circulating loop, a spraying reactor and a cooling medium thermotank. A gas pressure reducer, an air bottle and an air compressor are additionally connected to the front of a gas pressure pump; a vacuum pump and a pressure meter are connected outside a buffer tank; the reaction water circulating loop is connected with a plunger pump, a liquid flow meter, a valve, a reactor and a storage tank, and the front of the plunger pump is additionally connected with a water tank and a valve; the cooling medium liquid circulating loop is provided with a low temperature thermotank, and can provide cooling medium liquid for the buffer tank, the storage tank and the cooling medium thermotank. The invention can lead gas to fully contact with redaction water and be sprayed and atomized, increases gas-water contact area, shortens the induction time of the hydration reaction, greatly improve the generation speed of the gas hydrate, and realizes the quick generation of the gas hydrate, thereby being the device for efficiently preparing the gas hydrate.

Description

technical field [0001] The invention relates to a gas-liquid dispersion technology for synthesizing gas hydrates, in particular to a visualization device for preparing gas hydrates by jetting. Background technique [0002] Gas hydrate is a kind of cage-type enveloping crystal formed by certain gases (or volatile liquids) and water under low temperature and high pressure conditions. Different gases require different temperature and pressure conditions to form gas hydrates, and the types of gas hydrates formed are also different. Gas hydrates have the characteristics of large gas storage capacity, convenient transportation, and safe use. However, the technology for synthesizing gas hydrates is not yet mature, especially for gases that are difficult to form hydrates. The temperature and pressure conditions are not easy to control, and the hydration rate is also very slow. It is difficult to improve, so the application of this technology urgently needs a device for efficiently ...
