GAS HYDRATE COLLECTION DEVICE AND GAS HYDRATE COLLECTION METHOD

摘要

Provided are a gas hydrate collection device and a gas hydrate collection method for efficiently collecting gas hydrate. Massive gas hydrate m and sediment, together with water from the bottom 2 of water, are supplied to a gasification tank 5, the massive gas hydrate m and the sediment are separated from each other by means of a specific gravity difference, gas g in the gasification tank 5 is extracted and collected, and the sediment is discharged to the outside from a discharge port 12 formed in the gasification tank 5. The sediment deposited in the vicinity of the discharge port 12 is removed by jetting water from the vicinity of the discharge port 12 toward the inside of the gasification tank 5.
