[0002] Cracking fractionation structure refers to the process design in which cracking products are separated into different fractions according to boiling point ranges during the cracking process (such as steam cracking, catalytic cracking, etc.) in petrochemical or coal chemical industries.

[0003] However, in the current tire / plastic pyrolysis process, the composition of the oil and gas produced by pyrolysis is quite complex, and different types of oil are produced at different temperatures. Traditional pyrolysis simply extracts the oil from the tire or plastic, collects it, and then burns it as fuel. This method is extremely inefficient in the use of pyrolyzed oil and cannot generate relatively large economic value.

[0004] Therefore, in order to solve the above problems, a cracking fraction cutting structure is proposed. Utility Model Content

At this time, the oil and gas enter condenser 8 through the diversion pipe 4. The light oil and gas are condensed into light liquid oil in condenser 8 and stored in oil storage tank 10. When the temperature sensor 3 detects a temperature above 180℃, electric valve 7 opens and electric valve 6 closes. At this time, the oil and gas enter condenser 9 through diversion pipe 25.
