[0034] process flow
[0035] 1. Using waste plastic as raw material
[0036] Raw materials—drying—crushing—feeding—catalysis—cracking—condensation—filtration—products.
[0037] After the waste plastics are broken, send them into the cracking kettle 21 by means of pipeline 2 air delivery, and at the same time add 1-3‰ natural zeolite according to the weight ratio, and set an electronic induction breaker on the induction frequency conversion closed loop to control the pressure from being too high; temperature control Set the temperature on the device, set the temperature in the upper part of the kettle to 300C, set the temperature in the lower part of the kettle to 420C, and the outer bottom of the kettle to 500C. Keep the temperature in the electric induction cracking kettle at 350C-400C. After the setting is completed, start to heat up at an average speed. Catalytic cracking reaction time is 3-4 hours. During the process of temperature rise, cracking catalytic reaction occurs...
