GAS HYDRATE TRANSFER APPARATUS OF DEHYDRATOR IN GAS HYDRATE PRODUCTION PLANT

摘要

PROBLEM TO BE SOLVED: To provide a gas hydrate transfer apparatus of a dehydrator in a gas hydrate production plant capable of uniformly transferring GH slurry of a high concentration produced by being treated by a dehydration apparatus in the gas hydrate production plant from the dehydration apparatus to a feeding apparatus for feeding it to a subsequent step.;SOLUTION: A screw feeder 11 for feeding the GH slurry to the subsequent step is arranged at a side of an inner cylinder 3a of the dehydrator 3, and a scraping plate 12 advanced/retreated by a piston/cylinder mechanism 13 relative to the screw feeder 11 is provided at a position where a support part 14 by a piston rod 13a is deviated from a center in a height direction of the scraping plate 12. The scraping plate 12 is advanced on an advancement passage, and the GH slurry appeared on an upper part of the dehydrator 3 is scraped to the screw feeder 11. If a piston rod 13a is turned on a return passage and the scraping plate 12 is retreated while turning over it, the GH slurry is not scraped on the return passage.;COPYRIGHT: (C)2010,JPO&INPIT
