  • Method of and apparatus for recovering foaming gas of the foamed material
    Patent number: 5769333
    Abstract: A system including a method and an apparatus is disclosed for effectively separating a foamed heat-insulating material, such as insulated wall sections from used refrigeration equipment, into a foaming gas and a heat-insulating resin without any alteration and recovering them. A peeling portion for peeling a foamed heat-insulating material from a composite material containing the foamed heat-insulating material is included in a crusher provided with a high speed rotor having a plurality of hammers and a casing surrounding the rotor. A sorting portion is provided for sorting the foamed heat-insulating material with a tilting type wind force sorter having a limited tilting angle and a limited height of a wind tunnel. A pulverizing portion is provided for pulverizing the sorted foamed heat-insulating material and for separating a foaming gas therefrom. A condensing portion is provided for cooling and liquefying the separated foaming gas.
