The valve 6 provided in the transfer path 7 is closed, and the valve 9 provided in the communication pipe 8 is opened. In this state, a predetermined amount of solvent B, in this case, a solvent mainly composed of styrene monomer, is supplied to the solvent chamber / pyrolysis chamber 3 through the opening 18, and the styrofoam waste A is appropriately crushed into the melting chamber 5. Then, the raw material charging port 13 is filled and each chamber is closed.

The solvent chamber / pyrolysis chamber 3 installed in the heating furnace 1 is heated, then flows into the main flue 20, passes through the damper 19, and flows into the furnace from the combustion gas inlet 4a of the second heating furnace 4. .. The combustion gas is obstructed by the barrier 4c, makes a round in the counterclockwise direction in the furnace, and is sucked into the chimney 22 from the combustion gas outlet 4b through the flue 21. Therefore, the melting chamber 5 installed in the second heating furnace 4 is efficiently heated by the residual heat after heating the first heating furnace 2.

スチック廃棄物Ａの溶融は更に加速される。As the temperature of the solvent chamber / pyrolysis chamber 3 rises, the solvent B in this chamber is pushed up into the communication pipe 8 by the vapor pressure generated on the liquid surface and projects to the center of the top wall surface of the melting chamber 5. The high temperature solvent B, which has been poured from the nozzle end of the nozzle to the diffusion plate 17 immediately below it and scattered in all directions, is evenly distributed on the upper surface of the expanded polystyrene waste A that has begun to melt.
Therefore, the solvent containing styrene monomer as a main component rapidly dissolves the polystyrene foam waste A while chemically reacting with the polystyrene foam. At this time, if the valve 6 of the transfer passage 7 is opened somewhat so that the melt in the melting chamber 5 circulates via the transfer passage 7, the solvent / thermal decomposition chamber 3 and the communication pipe 8, The combustion heat of the burner 1 can be fully utilized, and the melting of the foamed plastic waste A is further accelerated.

When the valve 6 is opened, the foamed plastic melt in the melting chamber 5 is transferred to the solvent chamber / pyrolysis chamber 3.

出来る。In this state, the combustion gas from the burner 1 flows directly toward the chimney 22 without passing through the second heating furnace 4, as shown by the broken line b in FIG. To heat intensively. Therefore, the foamed plastic melt in this chamber is efficiently heated to become a vaporized product, which rises toward the reaction chamber 10 provided immediately above. Then, while coming into contact with the reforming catalyst layer (not shown) provided in the reaction chamber 10, it is reformed into an oily substance having a desired composition.
The gaseous oily substance is liquefied while passing through the condenser 12, and the condensed water is separated by an oil-water separation device (not shown) to become a required oily substance. If the transfer path 7 becomes clogged while the apparatus is in operation, the cleaning branch path 25 shown in FIG. 2 can be used for easy cleaning.
