Abstract

The invention relates to an atomizing nozzle, in particular to a heavy oil feed atomizing nozzle. The technical problem to be solved by the present invention is to provide a heavy oil feeding atomizing nozzle with small atomized particles, proper spraying speed and uniform atomization. In order to solve the above technical problems, the present invention provides such a heavy oil feed atomization nozzle, including a nozzle body, etc.; the nozzle body is a hollow cylinder, the nozzle body is provided with an inner cavity, and the outlet section at the left end of the nozzle body is provided with a nozzle. The nozzle body is equipped with an atomizing device, and the upper part of the feeding section at the right end of the nozzle body is provided with a raw material oil inlet. The present invention achieves the effects of smaller atomized particles, appropriate ejection speed, and uniform atomization. Due to the mixed atomization mode of water vapor and heavy oil feed in the inner cavity as described above, when the amount of heavy oil feed increases or decreases hour.

Description

Technical field [0001] The invention relates to an atomizing nozzle, in particular to a heavy oil feed atomizing nozzle. Background technique [0002] In the process of catalytic cracking (FCC) processing, the performance of the feed nozzle plays an important role in the cracking reaction and product distribution; especially when heavy oil is used as a raw material, this effect is particularly prominent. The well-atomized feed is in contact with the high-temperature regenerated catalyst 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, relevant domestic and foreign companies have been continuously developing and launching new and efficient heavy oil feed atomizing nozzles to meet the needs of the development of heavy oil deep proce...
