Abstract:
1. A system for treating an organic waste comprising: a preheating tank to preheat the organic waste, wherein the preheating tank includes a spiral heat exchange agitation tube to agitate the organic waste supplied into the preheating tank while preheating with heat of a heating medium by flowing the heating medium through the tube and swirling the tube; a pump to pressurize the organic waste; a high temperature and pressure treatment apparatus following the preheating tank and the pump, the organic waste being supplied to the high temperature and pressure treatment apparatus under pressure from the pump, the high temperature and pressure treatment apparatus producing a slurried material by treating the pressurized organic waste from the pump at a high temperature and a high pressure; a steam blowing means to blow steam into the organic waste in the high temperature and pressure treatment apparatus; wherein the high temperature and pressure treatment apparatus is formed as a continuous reaction tank to which the pressurized organic waste is continuously supplied from the pump and to which the steam is blown from the steam blowing means to cause a reaction while heating, pressurizing and agitating; a dehydration treatment apparatus following the high temperature and pressure treatment apparatus to dehydrate the slurried material from the high temperature and pressure treatment apparatus, the dehydration treatment apparatus producing a separated liquid product and a separated solid product, the separated solid product from the dehydration treatment apparatus comprising a sufficient combustible content to produce a fuel product from the separated solid product; and a water treatment apparatus following the dehydration treatment apparatus to treat the separated liquid product from the dehydration treatment apparatus.
