Patent ID: 7329395

Claim:
A treatment apparatus for organic waste, comprising: a reaction vessel for introducing and decomposing organic waste, said reaction vessel having an outlet end to remove decomposed organic waste as a treated fluid; said reaction vessel including; an internal vessel made of corrosion-resistant material; an external vessel made of pressure-resistant material provided for surrounding said internal vessel via a gap; and an interconnection pipe for interconnecting said gap and said internal vessel to transmit a pressure inside of said internal vessel and a pressure inside of said gap to each other, thereby to control inside of said gap and inside of said internal vessel to practically equal pressure; said internal vessel having a heating zone configured to heat said introduced organic waste to a temperature higher than a critical point of water, a reaction zone configured to hold and decompose said organic waste at a temperature higher than said critical point of water, and a cooling zone configured to cool said treated fluid containing a decomposition product of said organic waste; and said gap being adapted to be charged with high-pressure water or hydrogen peroxide water.
