METHANE FERMENTATION APPARATUS USING BIOMASS RESOURCE

摘要

PROBLEM TO BE SOLVED: To provide a methane fermentation apparatus using a biomass resource, from which the biogas produced by treating the biomass resource such as garbage in a methane fermentation tank can safely be supplied stably to equipment using a gas.

SOLUTION: An oxygen concentration meter 11 and an emergency shutoff valve 12 for shutting off a gas supplying line when the value measured by the oxygen concentration meter 11 exceeds a threshold are arranged on the gas supplying line at the succeeding stage of a gas holder 7 for storing the biogas produced by methane-fermenting the biomass resource in the methane fermentation tank 4.
