Impinging stream polyphase reactor

Abstract

The invention is an impingement flow multiphase reactor, which relates to liquid-liquid mixed multiphase reaction. The reactor mixes the high-viscosity and low-viscosity fluids uniformly into a low-viscosity emulsion at a lower temperature and in a short period of time through the raw material injection premixer, and then sprays out a ring-shaped liquid film at high speed through multiple jets hitting the nozzles of the reactor The phase impact strengthens the reaction, so that the reaction can be carried out quickly and fully. The impinging flow multiphase reactor introduced by the invention has simple structure, no stirring parts, is not easy to leak, has a large contact area of ​​reaction liquid, can realize rapid and efficient mixed reaction of immiscible fluids in large-scale production, and has high product selectivity. It can be applied to reaction devices with high fluid viscosity, liquid-liquid immiscibility and rapid mixing reaction between liquids in fine chemical industry, petrochemical industry, pharmaceutical industry, biochemical industry and other industrial processes, especially liquid acid catalyzed isobutane alkylation reaction .

Description

technical field [0001] The invention relates to a liquid-liquid mixed multiphase reaction, in particular to a multiphase reaction with high fluid viscosity and immiscible liquid-liquid, especially the isobutane alkylation reaction catalyzed by concentrated sulfuric acid or ionic liquid, belonging to petrochemical and environmental engineering , pharmaceutical engineering and other fields. Background technique [0002] With the rapid growth of the number of automobiles in my country, the impact of exhaust emissions on air pollution is increasing. The quality of oil products is an important factor affecting automobile exhaust emissions. To accelerate the upgrading of oil quality, how to produce clean products that meet the increasingly stringent environmental protection standards of the country Gasoline blending components are a major strategic demand for national resource environment / green manufacturing. Compared with other components, alkylated oil does not contain olefins a...

Problems solved by technology

However, the impingement flow mixer is easy to form a dead zone in the area away from the nozzle, which makes the distribution of the reaction product uneven, and it is still difficult to achieve a good mixing effect for the reaction between multiple high-viscosity liquids
