Embodiment Construction
[0042] When using a fluidized catalytic cracking device with a built-in rough cyclone tube-type settler of the present invention, the feedstock oil and recycled oil enter the riser 10, mix with the regenerated catalyst from the regenerator, and have a lifting effect in lifting steam or lifting dry gas Downward and upward mixing flow, while the catalytic cracking reaction occurs. The reaction oil gas and catalyst enter the coarse rotary 8 at the outlet of the riser 10 for a separation. The separated oil gas and the oil gas stripped from the stripper are combined with the steam, and carry a small amount of unseparated fine catalyst particles, and enter the tube settling The upper part of the tank 5 enters the top spin 6 for secondary separation, and the separated oil and gas flow into the gas collection chamber 7 and are quickly drawn out by the oil and gas pipeline to the fractionation tower, where the catalyst separated by the rough spin 8 and the top spin 6 separate The catal...
