PROBLEM TO BE SOLVED: To provide a liquefaction treatment of cooling thermal cracking gas produced by dry distillation of waste to condensate and recovering the resultant oil which improves the performance of recovering an oil from a thermal cracking gas by a simple configuration and recovers an oil efficiently.SOLUTION: A liquefaction apparatus 20 which converts thermal cracking gas produced by treatment of combustible waste into an oil by condensation and includes a tank part 30 containing cooling water 37 and a gas passage part 50 which is provided within the tank part 30 and allows the thermal cracking gas guided to the tank part 30 to pass through, and the gas passage part 50 has a zigzag structure in which a first inclined passage part 51 inclined downward in a specified direction and a second inclined passage part 52 inclined downward in a direction different form the specified direction are arranged vertically alternately. |
