Embodiment 1
[0034] A device for blending catalytic oil slurry in delayed coking process, comprising separately established oil slurry tank m, oil slurry pump o, oil slurry heating furnace n, the three are connected in sequence, the outlet of oil slurry heating furnace n is connected to the delayed coking device slag The outlet of oil heating furnace b is connected.
[0035] By setting forth the working method of this device, the present invention can be better understood:
[0036] The residual oil 1 is fed into the raw material buffer tank a, pumped out by the raw material oil pump l, enters the fractionation tower e through the heat exchanger g, and then pumped out by the heating furnace feed pump f and sent to the residual oil heating furnace b to be heated to 490-500 °C; The slurry 2 feeds into the slurry tank m, is pumped out by the slurry pump o and sent to the slurry heating furnace n to be heated to 510-550°C; the high temperature coking oil 5 at the outlet of the residual oil heat...
