APPARATUS AND METHOD FOR PRODUCING ENERGY AND MANUFACTURING ORGANIC FERTILIZER BY USING EXCRETIONS, WASTE WATER AND SLURRY

摘要

Disclosed is an apparatus for producing energy and an organic fertilizer using livestock excreta, wastewater and slurry. The apparatus includes; a foreign material removal unit removing foreign materials from raw materials input into a charge tank; a fermentation unit supplied with the raw materials from the foreign material removal unit and with high-temperature clean air and heat, and fermenting the raw materials; a slurry dry and transfer unit supplied with the fermented raw materials from the fermentation unit, drying the raw materials using heat, and removing harmful components from the raw materials; a heater unit supplied with methane fermentation gas (MFG) from the fermentation unit, oxygen, and an auxiliary fuel, and burning the supplied mixture to generate heat; an MFG collection tank provided between the fermentation unit and the heater unit so as to collect the MFG produced from the fermentation unit; a boiler unit installed at a rear end of the heater unit, and generating steam; a heat exchanger supplied with waste heat from the boiler unit, exchanging heat with external clean air, and supplying the high-temperature clean air to the fermentation unit; and a separator separating the foreign materials from the raw materials transferred from the slurry dry and transfer unit.
