The invention discloses a granulation device for continuously preparing a hydrate, which comprises a hydrate reactor, a steady-flow liquid supply system, a steady-flow gas supply system, a temperaturecontrol system, a granulation extrusion system and a driving control system. The hydrate reactor is a horizontally placed pressure-bearing circular pipe with an air inlet at the bottom and a liquid inlet at the side; the steady-flow liquid supply system feeds a solution to the hydrate reactor at a constant speed; the steady-flow gas supply system is used for introducing gas into the hydrate reactor at a constant speed; the temperature control system is used for controlling the temperature of the gas and solution introduced into the hydrate reactor; the granulation extrusion system is a magnetic piston placed in the hydrate reactor; and the driving control system is placed outside the hydrate reactor to control movement of the magnetic piston in the hydrate reactor. According to the granulation device, hydrate formation, granulation and gas-liquid separation are continuously completed in the same device, thereby realizing rapid and efficient continuous preparation of the hydrate.
Description
technical field [0001] The invention relates to the field of hydrate preparation, in particular to a granulation device for continuously preparing hydrate. Background technique [0002] Gas hydrate (hereinafter referred to as hydrate) is a kind of small molecular gas (such as CH 4 、C 2 h 6 , CO 2 etc.) and the main body of water molecules in the low temperature, high pressure environment to form a non-stoichiometric crystalline cage compound. According to this property, hydrates can be used to store and transport natural gas, separate gas mixtures, desalinate seawater, concentrate aqueous solutions, etc. The existing hydrate production equipment is difficult to produce hydrate stably, the production efficiency of the equipment is low, and the generated hydrate solid is difficult to separate from the remaining solution, which leads to increased production costs and cannot produce hydrate economically on an industrial scale. Contents of the invention [0003] The purpos...
