THERMAL HYDROLYSIS REACTION ANAEROBIC DIGESTION SYSTEM OF ORGANIC WASTE

摘要

The present invention relates to a thermal hydrolysis anaerobic digestion system of organic waste capable of increasing the amount of biogas generated by thermally hydrolyzing organic waste using high temperature and high pressure steam and introducing a two-stage cooling device. To this end, the present invention provides a pretreatment unit for pretreating according to the characteristics of organic waste; A thermal hydrolysis unit preheating the preheated organic waste, supplying steam to the preheated organic waste to thermally hydrolyze, and secondary cooling the thermally hydrolyzed organic waste; A boiler unit comprising a waste heat boiler that generates the steam through waste heat and an auxiliary boiler that generates the steam through digestion gas and LNG (Liquefied Natural Gas); And an anaerobic digester for separating organic matter from the secondary cooled organic waste through methanogenic bacteria.
