Embodiment 2
[0014] Embodiment 2. In this embodiment, the height of the first and second reactors 1 and 2 is 5 meters, and the height of the cracking section b is 15 meters. The third reactor 3 has an inverted conical structure with a cone angle of 20 degrees, and its height is 4 meters. The fourth reactor 4 is a zoom-shaped structure, and the longitudinal section structure of the diameter-reducing zone 13 is as follows: image 3 As shown, the diameter of the reduced-diameter zone 13 is 0.7-1 times of the diameter of the non-diameter-reduced zone 14, and the height is 10 meters. Others are the same as embodiment 1.
