Inside generally it is arranged on by the various stripper plants of stripping section in device, oil and gas sedimentation separation in settler, catalyst two-phase transportation
To regenerator.Without installation afterburning nozzle, this sedimentation has 2 points of deficiencies：Slurry oil caused by one side catalytic unit only has
By getting rid of outside and without good utilization means；On the other hand the quantity of steam deficiency that existing catalytic unit needs will also pass through device
Guarantee plant running is attracted outside, adds the energy consumption of device.
The content of the invention
The utility model provides a kind of catalytic reaction settler with afterburning function, to solve to carry in above-mentioned background technology
The problem of going out.

Quantity is identical and is arranged in pairs, and at least two pairs of baffle plate, each pair of baffle plate vertically arranges, the bottom in settler body stage casing
It is provided with catalyst outlet, settler body epimere is internally provided with primary cyclone and two-stage cyclone separator, and one
Level cyclone separator and two-stage cyclone separator are connected, and oil and gas outlet is provided with the top of settler body epimere, and described is heavy
Afterburning nozzle is provided with the side wall in drop device body stage casing, slurry oil is injected the inside in settler body stage casing, institute by afterburning nozzle
A stripped vapor distributor is provided with below the baffle plate stated, steam enters settler body stage casing by stripped vapor distributor
Inside.
Described baffle plate shares three pairs, and the port of export of described afterburning nozzle is located at the space between two pairs of baffle plates of downside
Place.At least two, described afterburning nozzle, each afterburning nozzle are evenly distributed on around settler this body sidewall.
The beneficial effects of the utility model are：The utility model has installed afterburning nozzle, energy additional on the basis of existing technology
It is enough that slurry oil caused by catalytic cracking unit is made full use of, slurry oil is adsorbed by the flowing of settler stripping section catalyst
In the catalyst, part slurry oil vaporizes, and big portion, which is streamed to regenerator and burnt, becomes heat, the steam exhaling amount of device is improved, to oil
The trans-utilization of slurry serves positive effect.
