NOZZLE FOR INJECTION OF FLUID MEDIUM INTO REACTOR WITH FLUIDISED BED Russian patent published in 2015 - IPC B01J8/18 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to a nozzle assembly for injection of fluid medium into the reactor with circulating fluidised bed, in particular for injection of heavy oil products, such as fuel oil and bitumen, into coking reactors in a fluidised bed. The reactor with circulating fluidised bed has the bottom input hole for fluidising gas and units of nozzles for supply of raw materials for liquid raw materials (22) of heavy fractions of oil products and steam (23, 24) for dispersion. The reactor also has the pre-mixer (13) for combining of liquid heavy fractions of raw materials of oil products with steam for dispersion containing throttle coning in the flowing pipeline. Besides, the reactor has the flowing pipeline section downstream the pre-mixer (13) and the outlet nozzle (29). The reactor also has a dispergator with the form of clover leaf. The wall of each petal limits a segment of a hollow cone. Axes of hollow cones are crossed symmetrically with the central axis of the dispergator which is implemented with multipetal output passage with the increasing area of cross section.

EFFECT: increase of surface area for interaction and entrainment between the flow and the fluidised layer of solid substances.
