PROBLEM TO BE SOLVED: To reduce energy consumption of a hydrate solid drying device. ! SOLUTION: A hydrate solid drying device includes: a preheating heat exchanger 11 preheating a hydrate solid using hot water and a gas medium as a heat source; a fluidized bed dryer 12 heating the preheated hydrate solid using compressed steam, evaporating water contained in the hydrate solid to separate the water as steam, and supplying a dried solid; a heat-recovery heat exchanger 15 cooling the dried solid using the gas medium as a cold source, and recovering heat; and a gas compressor 16 increasing a temperature of the gas medium recovering the heat by compressing the gas. The heated gas medium is supplied together with hot water formed by condensing the compressed steam in the fluidized bed dryer 12 to the preheating heat exchanger 11. The preheating heat exchanger 11 and the heat-recovery heat exchanger 15 are counterflow heat exchangers. ! COPYRIGHT: (C)2015,JPO&INPIT |
