<p>PURPOSE: Provided are a cracking device for polymer waste having pressure transducer system, which changes a pressure inside the system and maintains a quality of the resulting oil to desired level, and which increases yields, and a cracking method. CONSTITUTION: The device comprising a melting unit(21) for melting a polymer waste, a reactor(22) for cracking a molten waste, a quenching bath(23) for cooling a gas formed in the reactor(22), and a condenser(25) for condensing a product formed in the bath(23), wherein the melting unit(21) is communicated with the bath(23) and the condenser(25), is characterized by further comprising a first gas discharge pipe, which discharges a gas from the inside of the condenser(25) and has a first control valve for controlling a discharge of the gas; a second gas discharge pipe, which discharges a gas from the inside of the condenser(25) and has a second control valve for controlling discharge of the gas; and a suction pump for inhaling a gas from the inside of the condenser(25).</p> |
