PURPOSE: A device for generating bio gas of organic waste is provided to minimize sludge generation quantity while reducing energy consumption to the utmost by generating the bio gas in an anaerobic condition through a dry-typed anaerobic digester. CONSTITUTION: A device for generating bio gas of organic waste generates methane gas by fermenting the organic waste in an anaerobic condition. The bio gas generating device includes a grinder(110), a foreign material selector(120), an organic waste reservoir(130), a dry-typed anaerobic digester(140), an organic waste supply unit, a gas reservoir(160), a heating source(170), a sludge retaining tank(180), and a sludge discharge unit. The grinder pulverizes the organic waste to predetermined size. The foreign material selector selects metal foreign materials from the organic waste. The organic waste reservoir stores the organic waste. The dry-typed anaerobic digester generates the methane gas by fermenting the organic waste supplied from the organic waste reservoir. The gas reservoir stores the bio gas generated from the bio gas. The heating source heats an inner side of the dry-typed anaerobic digester to the constant temperature. The sludge retaining tank stores the waste sludge. The sludge discharge unit transfers the waste sludge to the sludge retaining tank. |
