1. A gas hydrate desalination system, comprising:
a gas hydrate generating and conveying unit;
a gas-liquid supplying and mixing unit; and
a gas hydrate dissociating and resolving unit;
wherein the gas hydrate generating and conveying unit includes:
a hydrate crystallizer reactor with a detachable water jacket surrounding portion of the hydrate crystallizer reactor and a plurality of thermocouples disposed within the hydrate crystallizer reactor;
a detachable lid of the hydrate crystallizer reactor having a liquid inlet and a gas inlet;
at least two sapphire glass lenses disposed on an outer surface of the detachable lid;
a pressure sensor disposed inside the hydrate crystallizer reactor;
a plurality of lid cameras disposed outside the hydrate crystallizer reactor proximal to the sapphire glass lenses;
an exit concentrate channel at a bottom of the hydrate crystallizer reactor that has a length in a longest dimension of from 0.6 to 0.8 times a length of the hydrate crystallizer reactor; and
heat transfer tubes configured to cool hydrate crystals formed in the hydrate crystallizer reactor;
wherein the gas-liquid supplying and mixing unit includes:
a liquid storage tank fluidly connected to a first pump that is fluidly connected to the hydrate crystallizer reactor through the liquid inlet; and
a gas feed cylinder fluidly connected to a second pump that is fluidly connected to the hydrate crystallizer reactor through the gas inlet;
wherein the gas hydrate dissociating and resolving unit includes:
a third pump fluidly connected to the exit concentrate channel, a second fraction column, and a sieve filter column;
the sieve filter column is fluidly connected to a first fraction column through a sieve filter outlet;
the first fraction column is fluidly connected to a first fraction column channel through a first fraction column outlet and the first fraction column channel is fluidly connected to a brine column through the first fraction column outlet;
the second fraction column is fluidly connected to a second fraction column channel through a second fraction column outlet and the second fraction column channel is fluidly connected to the brine column through the second fraction column outlet; and
the first fraction column outlet, the second fraction column outlet, and a brine column inlet are disposed at a same height relative to the brine column.
