Description

Gas-liquid distribution device based on multistage fluid momentum gradient regulation and control Technical Field The application relates to the field of gas-liquid distribution devices, in particular to a gas-liquid distribution device based on multistage fluid momentum gradient regulation. Background In the reaction equipment in the fields of chemical industry and pharmacy, the uniform mixing of liquid and filler directly affects the reaction efficiency and the product quality. The prior liquid collector mostly adopts a single-layer or double-layer distribution structure, such as a single-layer porous plate, a conical distributor or a combined tubular distributor, and liquid is primarily dispersed through holes or diversion trenches. The structure can meet the basic distribution requirement under the working condition of low-flow and low-viscosity liquid, but when a complex medium with high-flow and high-viscosity or containing solid-phase particles is treated, the radial flow velocity difference is easy to generate after the liquid passes through the distribution structure, so that the liquid forms channeling or dead zones in the packing layer. The fundamental reasons are that the traditional distribution structure has hydrodynamic defects that the single-layer distribution is limited by the structural strength requirement, the aperture ratio and the distribution uniformity are inversely related, and the double-layer distribution can improve local flow, but the interference phenomenon of fluid between layers can cause secondary distribution disorder, and the self-adaptive adjustment capability is lacking particularly under the dynamic working condition. Such distribution defects not only reduce mass transfer efficiency, but also cause local overheating or incomplete reaction, forcing enterprises to compensate efficiency loss by prolonging reaction time or increasing cycle times, resulting in rising energy consumption and increasing production cost. In recent years, with the wide application of novel fillers such as nanocatalysts, the demands for fine control of liquid distribution are more urgent. The traditional liquid collector has the defects that the surface utilization rate of high-activity filler is generally lower than 65% due to insufficient distribution uniformity, and the filler is easy to break due to local scouring. In addition, the existing structure is difficult to adapt to the compact design trend of the modularized reactor, and the small-size development of equipment is restricted due to the fact that the volume of the distributor is too large. These problems expose that conventional distribution techniques have difficulty meeting the dual demands of modern continuous production processes for process intensification and equipment intensification. Therefore, developing a novel liquid distribution technology has remarkable engineering value for improving the comprehensive performance of the reactor, reducing unit energy consumption and prolonging the service life of the catalyst, and particularly plays an important technical promotion role in the fields sensitive to reaction uniformity, such as fine chemical synthesis, biopharmaceutical and the like.
