Abstract

The invention relates to a heavy oil feeding and atomizing nozzle, in particular to a heavy oil feeding and atomizing nozzle for oil processing, and aims to provide the heavy oil feeding and atomizing nozzle which is used for oil processing and is relatively small in atomized particle, proper in spray speed and uniform in atomizing. The nozzle comprises a nozzle body and the like; the nozzle body is a hollow cylinder; an inner cavity is formed in the nozzle body; a spray head is arranged at the outlet section of the left end of the nozzle body; an atomizing device is arranged in the nozzle body; and a raw oil inlet is formed in the upper part of the feeding section of the right end of the nozzle body. The nozzle realizes the effects of being relatively small in atomized particle, proper in spray speed and uniform in atomizing; due to the mixing atomizing manner of water vapor and heavy oil feed in the inner cavity, when the heavy oil feed amount is increased or decreased, the volume flow change of oil and vapor two-phase flow is relatively small, the atomizing quality cannot be obviously affected, and the nozzle is good in operation flexibility and high in reliability.

Description

technical field [0001] The invention relates to a heavy oil feed atomization nozzle, in particular to a heavy oil feed atomization nozzle for petroleum processing. Background technique [0002] In the catalytic cracking (FCC) process, the performance of the feed nozzle plays an important role in the cracking reaction and product distribution; especially when heavy oil is used as raw material, this effect is particularly prominent. The well-atomized feed and the high-temperature regenerated catalyst contact for a short time to carry out a violent catalytic cracking reaction, which can increase the yield of light oil, reduce the yield of coke, improve product distribution, prevent excessive cracking, and eliminate coking in the riser reactor phenomenon, bringing considerable economic benefits. Therefore, related enterprises at home and abroad have been continuously developing and launching new and efficient heavy oil feed atomization nozzles to meet the needs of the developme...
