FIELD: oil processing industry; mixing devices of the reactors of the hydrocarbons catalytic cracking. ^ SUBSTANCE: the invention is pertaining to mixing devices of the reactors of the hydrocarbons catalytic cracking and may be used in oil processing industry. The mixing device of the reactor of the hydrocarbons catalytic cracking contains the central collector of the granulated catalytic agent with the annular diaphragm and the peripheral pipelines for discharge of the catalytic agent, the internal injector for feeding of the two-phase gas-raw mixture (GRM) and the mixing chamber. Additionally the mixing device contains: the assembly of the preliminary mixing of the liquid and steam stages, consisting of the central fairing and three or more guiding vanes mounted at an angle of 45-60° to the axis of the fairing; the assembly of dispersion of the GRM, which is mounted in front of the injector and representing the cylindrical pipe with the holes in its wall for the steam supply arranged at an angle, which corresponds to the angle of the spin of the stream of the GRM coming out from the assembly of the preliminary mixing. The injector has the diffuser and the fairing with the through vertical hole. The invention increases conversion of the raw material in the reactor of the catalytic cracking and reduces formation on the catalytic agent of the coke high the high contents of hydrogen causing the thermal destruction of the catalytic agent in the regenerator. ^ EFFECT: the invention ensures the increased conversion of the raw materials in the reactor of the catalytic cracking, reduced formation on the catalytic agent of the coke high the high contents of hydrogen causing the thermal destruction of the catalytic agent in the regenerator. ^ 1 ex, 1 tbl, 1 dwg |
