Gas hydrate production apparatus

A gas hydrate production apparatus for reacting a raw gas with a raw water to thereby form a slurry gas hydrate, and for removing water from the slurry gas hydrate by means of a gravitational dewatering unit, the gas hydrate production apparatus characterized in that

• the gravitational dewatering unit includes:
• a cylindrical first tower body;
• a cylindrical dewatering part disposed on top of the first tower body;
• a water receiving part disposed outside the dewatering part;
• and
• a cylindrical second tower body disposed on top of the dewatering part, and
• the dewatering part is provided with an innumerable number of any one of through holes and slits.

A gas hydrate production apparatus for expelling a gas hydrate dewatered by means of a gravitational dewatering unit with an expelling unit disposed on a top portion of the gravitational dewatering unit, the gas hydrate production apparatus characterized in that

• the expelling unit includes:
• a crusher section positioned on the top portion of the dewatering tower;
• and
• a transfer section positioned behind the crusher section.

A gas hydrate production apparatus for reacting a raw gas with a raw water to thereby form a slurry gas hydrate and for removing water from the slurry gas hydrate by means of a gravitational dewatering unit, the gas hydrate production apparatus characterized in that

• the gravitational dewatering unit includes:
• an introducing part from which a gas hydrate slurry is introduced;
• a dewatering part that removes unreacted water in the gas hydrate slurry;
• a cylindrical main body formed of an exhausting part that leads out the gas hydrate dewatered by the dewatering part;
• and
• a water receiving part that receives a filtrate separated from the gas hydrate by the dewatering part, and
• the dewatering part is washed by raising and lowering a liquid surface in the water receiving part.

A gas hydrate production apparatus including:

• a pressure-tolerable container;
• and a stirring blade at an inner lower portion of the pressure-tolerable container, and supplying a hydrate-forming gas in an bubble form to water in the pressure-tolerable container to thereby form a gas hydrate, the gas hydrate production apparatus characterized by comprising:
• a upward-conveying unit which conveys the formed gas hydrate upward while bringing the gas hydrate into contact with a side surface of the pressure-tolerable container;
• a discharging unit that include
• a discharge path whose one end is opened at an inner surface of the pressure-tolerable container, and
• a discharging feeder installed in the discharge path;
• and further
• a discharging blade which introduces the gas hydrate conveyed by the upward-conveying unit into the discharge path, characterized in that
• the upward-conveying unit rotates a convey path formed of a belt-like spiral body along the inner surface of the pressure-tolerable container with a vertical direction in the pressure-tolerable container serving as a rotation shaft direction.
