Dynamic tangential flow tubular reactor

Abstract

The invention relates to the field of biological medicine reaction devices, and discloses a dynamic tangential flow tubular reactor which comprises a reactor shell, a rotating shaft arranged in the reactor shell, a rotating fixing device used for connecting the rotating shaft with the reactor shell, and a feeding and discharging port assembly arranged on the outer wall surface of the reactor shell, a plurality of stirring columns are vertically arranged on the outer wall surface of the rotating shaft; a reaction cavity is formed between the inner wall surface of the reactor shell and the outerwall surface of the rotating shaft; the reactor further comprises a scraper assembly arranged on the inner wall surface of the reactor shell. The dynamic tangential flow tubular reactor is used for solving the problems of failure shutdown, material waste and difficulty in cleaning of the reactor caused by easy adhesion of materials on the rotating shaft of the reactor.

Description

technical field [0001] The invention relates to the field of biomedical reaction devices, in particular to a dynamic tangential flow tube reactor. Background technique [0002] The tubular reactor is a continuous operation reactor with a tubular shape and a large length-to-diameter ratio. The tubular reactor has small backmixing, so the volumetric efficiency (production capacity per unit volume) is high, and it is especially suitable for occasions that require a high conversion rate or have side reactions in series. In addition, the tubular reactor can realize segmented temperature control. [0003] For tubular or plug-flow reactors, theoretically speaking, the physical and chemical reactions between the reactants in the liquid phase, the contact or collision between them are mainly caused by factors such as Brownian motion or gravity. Therefore, in some systems, the kinetics of this reaction process are slow or cannot be optimized. Most reactors in the prior art have the...

Problems solved by technology

[0005] The present invention aims at overcoming at least one defect (deficiency) of the above-mentioned prior art, and provides a dynamic tangential flow tube reactor, which is used to solve the problem of shutdown and waste of materials caused by the easy adhesion of materials on the rotating shaft of the reactor. And the difficulty of cleaning the reactor

The setting of the scraper assembly can avoid the waste of adhering materials, avoid the failure of the machine due to adhesion, and avoid the problem of difficult cleaning of the reactor after the reaction is completed.
