    摘要： Disclosed is an apparatus for decomposing a polyurethane resin and recovering the decomposed polyurethane resin as a polyamine compound and a polyol compound, said apparatus including: a fluidizer that fluidizes the polyurethane resin as a target compound of hydrolysis decomposition; a reactor that hydrolyzes the fluidized target compound of decomposition with either one of supercritical water and high-temperature high-pressure water to a decomposition product mixture; a water supplier that feeds either one of supercritical water and high-temperature high-pressure water to the reactor; and a post-processor that causes the decomposition product mixture discharged from the reactor to be subjected to a post treatment procedure, such as dehydration, addition, distillation, separation, and liquid separation to recover the polyamine compound and/or the polyol compound.
    According to the present invention, there can be provided an apparatus of decomposition and recovery that continuously decomposes and recovers polyurethane resin with high-temperature high-pressure water or supercritical water, which advantageously reduces the required energy cost, reduces the size of the whole apparatus, removes foreign substances from the shredder dust, and decreases the required quantities of substances for decomposition.
