Production and transportation system for natural gas hydrates

A production and transportation system for natural gas hydrates, comprising a gas storage reservoir, a plurality of hydrate storage and transportation tanks, a refrigerator, a pressure regulating valve, a liquid storage tank, a living quarter/surrounding user, a hydrate storage reservoir, a plurality of connecting pipes, a plurality of one-way gas valves, a plurality of one-way liquid valves, and a plurality of optional liquid pumps;

• wherein first input ends of the plurality of hydrate storage and transportation tanks are connected in parallel through a first plurality of connecting pipes of the plurality of connecting pipes and then connected with an output end of the gas storage reservoir through the pressure regulating valve, and an output end of the liquid storage tank is connected with a third optional liquid pump and then sequentially connected with second input ends of the plurality of hydrate storage and transportation tanks through a second plurality of connecting pipes of the plurality of connecting pipes and the plurality of one-way liquid valves;
• output ends of the plurality of hydrate storage and transportation tanks are connected in parallel through a third plurality of connecting pipes of the plurality of connecting pipes and then connected with an input end of the living quarter/surrounding user through a first optional liquid pump, and an output end of the living quarter/surrounding user is sequentially connected with third input ends of the plurality of hydrate storage and transportation tanks;
• the plurality of one-way gas valves are respectively arranged on the first plurality of connecting pipes connected in parallel between the first input ends of the plurality of hydrate storage and transportation tanks and the gas storage reservoir;
• the plurality of one-way liquid valves are respectively arranged on the second plurality of connecting pipes connected in parallel with the output ends of the plurality of hydrate storage and transportation tanks;
• the refrigerator is connected with the hydrate storage reservoir to refrigerate the hydrate storage reservoir, a natural gas hydrate transportation vehicle is stored in the hydrate storage reservoir, and the plurality of hydrate storage and transportation tanks are transferred to the natural gas hydrate transportation vehicle after the natural gas hydrates are generated;
• water-insoluble hydrate thermodynamic additives are added in the plurality of hydrate storage and transportation tanks, and a density of the water-insoluble hydrate thermodynamic additives is less than a density of water;
• and bottoms of the plurality of hydrate storage and transportation tanks are provided with valves and valve covers for closing the valves.
