Description

Technical Field

[0001] This utility model relates to the field of chemical reactors, and in particular to an industrial-grade dynamic multi-tube internal turbulence reactor. Background Technology

[0002] In chemical production, many special chemical reactions exist, such as rapid, strongly exothermic / endothermic reactions, reactions involving high-viscosity media or solid-liquid multiphase reactions, and reactions sensitive to residence time distribution. These reactions require extremely narrow residence time distributions (approximate plug flow) to ensure uniform reaction rates of all materials and reduce byproduct formation. Dynamic tubular reactors exhibit plug flow, minimizing backmixing and improving reaction selectivity. To accommodate these special reactions, existing technologies often employ static mixing tubular reactors and stirred tank reactors. However, these reactors present several technical challenges. For example, the mixing intensity in static mixing tubular reactors depends on flow rate; at low flow rates or high viscosity conditions, the mixing effect significantly decreases. Furthermore, for materials containing solid particles or prone to aggregation and coking, static elements easily form stagnant dead zones, leading to blockages and cumbersome periodic cleaning. Especially for strongly exothermic reactions, jacketed heat exchange alone may not be sufficient to remove heat in time, resulting in localized temperature runaway. The shape and performance of the reactor mixing elements are fixed, preventing flexible adjustment of the stirring intensity based on reaction progress (e.g., viscosity changes, reaction stages). Mechanically stirred batch reactors present several challenges: Dynamic sealing issues exist: the dynamic sealing point where the agitator shaft penetrates the reactor wall is a potential source of leakage, posing a significant safety hazard for highly hazardous, high-pressure, or highly toxic materials. Wide residence time distribution: particularly in batch reactors, severe backmixing occurs, making them unsuitable for continuous reactions requiring high selectivity. Scale-up effects: mixing and heat transfer efficiencies may change during scale-up, resulting in complex scale-up patterns. High energy consumption: maintaining continuous mechanical stirring requires energy. Utility Model Content
