Problems solved by technology

However, the mixing of high-viscosity reactants with other reactants is not satisfactory. In addition, the entire reactor system uses a riser, two horizontal tanks and a downcomer, and the equipment is huge and the structure is not compact enough.

Abstract

The invention provides a novel liquid-liquid multi-phase reactor device, comprising three different structures: an injection-typed circumfluence reactor, an impact flow lifting pipe reactor and a reinforced mass transfer gathering beam fibre filling material reactor; wherein, the injection-typed external circumfluence reactor (shown as figure 1) uses kinetic energy generated by the liquid injection to lead the reaction liquid which can be circulated used to circularly flow in the reactor, to be excellently mixed and reacted; the impact flow lifting pipe reactor (shown in figure 5) leads three reaction liquids to pass through multi-time butt-impact, crushing and mixing and carry out the reaction in the lifting pipe; the reinforced mass transfer gathering beam fibre filling material reactor (shown in picture 9) is internally provided with a plurality of fibre silks, so as to lead the reaction liquid to flow downwards from the surface of the fibre silk and to form two liquid film layer to carry out the reaction. The reactor of the invention has good liquid crushing and mixing effect and large liquid-liquid contact area, is widely applied to the fields of petroleum, chemicals, environments, etc., is especially suitable for the reaction between high viscosity liquid and liquid, such as ion liquid catalysis alkylation, P-noke method oil product catalytic oxidation reaction, etc.

Description

technical field [0001] The invention relates to novel liquid-liquid multiphase reactor equipment, in particular to liquid-liquid-liquid multiphase reactor equipment with relatively high viscosity, belonging to the fields of petroleum, chemical environment, biology and the like. Background technique [0002] The mixing effect of the immiscible solution-liquid two phases has an important influence on the conversion and selectivity of the liquid-liquid reaction. At present, there are many types of equipment for liquid-liquid two-phase mixing, such as stirred tanks, static mixers, impinging flow mixers, etc. [0003] A common stirred tank is mainly composed of a stirring chamber, a baffle, a stirring device and a sealing device. The device has a wide range of applications, mainly intermittent operation. The time scale of mixing is between several minutes and several hours, and it is often used in reaction systems with relatively slow reaction rates. However, due to the introd...
