Claim Text:
1. A device for manufacturing natural gas hydrate, comprising: a raw water tank configured to store raw water; an ice slurry generation unit configured to produce ice slurry in a normal pressure condition out of the raw water which supplied above zero degrees Celsius from the raw water tank, the ice slurry having 13-20% of ice at normal pressure; a first pipe having one end thereof connected to the ice slurry generation unit so as to allow the ice slurry to be discharged from the ice slurry generation unit and having a high-pressure pump interposed therein for increasing pressure on the ice slurry; a hydrate preparation reactor connected to the other end of the first pipe and configured to generate natural gas hydrate slurry by having the pressurized ice slurry flowed thereinto and natural gas supplied thereto and mixed with each other; a second pipe having one end thereof connected to the hydrate preparation reactor so as to allow the natural gas hydrate slurry to be discharged; a dehydrating portion connected to the other end of the second pipe and configured to dehydrate the natural gas hydrate slurry; a raw water recovering line configured to return the water separated by the dehydrating portion to the ice slurry generation unit for use in manufacture of the ice slurry; and a back pressure regulator interposed in the raw water recovering line for maintaining a pressure of the dehydrating portion.
