Abstract

The invention discloses a multi-inlet gas-liquid two-phase cyclone feeding downward-spray atomizing nozzle, and can effectively avoid the problems, such as coarse atomization particle size, material center convergence and low distribution uniformity degree, existing in an existing structure. A basic principle is to promote the atomization and dispersion of liquid-phase materials by strengthening the shearing action between gas and liquid phases. The multi-inlet gas-liquid two-phase cyclone feeding downward-spray atomizing nozzle is mainly composed of a top liquid-phase inlet (1), a tangentialliquid-phase inlet (2), a tangential gas-phase inlet (3), a gas-liquid two-phase mixing chamber (4), and a scaled nozzle body (5); the top liquid-phase inlet (1) is eccentrically welded on the top ofthe gas-liquid two-phase mixing chamber (4); the tangential gas-phase inlet (3) is eccentrically welded on one side of the gas-liquid two-phase mixing chamber (4); the tangential liquid-phase inlet (2) is eccentrically welded on the other side of the gas-liquid two-phase mixing chamber (4); the scaled nozzle body (5) is integrally processed with the gas-liquid two-phase mixing chamber (4). The multi-inlet gas-liquid two-phase cyclone feeding downward-spray atomizing nozzle disclosed by the invention can well achieve the atomization and dispersion of the liquid-phase materials, so that the materials are more evenly distributed in the catalyst bed of a fixed bed reactor.

Description

technical field [0001] The invention relates to a feed atomizing nozzle used for material distribution in a fixed-bed reactor, belonging to the field of petrochemical equipment. Background technique [0002] Fixed bed reactor is a common reactor type in petrochemical field. Feed atomization nozzle is one of the key equipment of fixed bed reactor, its structure directly affects the distribution of gas-liquid two-phase materials in the catalyst bed, and then affects the reaction efficiency and product yield. The feed nozzle with good atomization performance can achieve uniform distribution of materials, avoid local overheating of the bed and coking and deactivation of the catalyst due to local reactions, thereby improving the service life of the catalyst. Studies have shown that the uniformity of material distribution by the feed atomization nozzle directly determines the state of the material entering the bed. Contents of the invention [0003] The invention relates to a ...
