Description
Technical Field
The invention relates to the field of biomedical reaction devices, in particular to a dynamic tangential flow tubular reactor.
Background
The tubular reactor is a continuously operated reactor which is tubular and has a large length-diameter ratio. The tubular reactor has small back mixing, so that the tubular reactor has high volumetric efficiency (unit volume production capacity) and is particularly suitable for occasions requiring higher conversion rate or having series side reactions. In addition, the tubular reactor can realize segmented temperature control.
In the case of a tubular or plug flow reactor, theoretically, the physical and chemical reactions between reactants in the liquid phase occur, and the contact or collision between the reactants occurs mainly due to brownian motion or gravity. Thus, in some systems, the kinetics of this reaction process are slow or cannot be optimized. Most reactors in the prior art have the problems of nonuniform mixing and inconsistent reaction rates at different positions of the reactor due to poor heat exchange effect.
The Chinese patent 'a novel heat-exchangeable stirring shaft and tubular reactor' (application number: 201621025718.7, published: 2017-05-10) discloses a novel heat-exchangeable stirring shaft and tubular reactor, which belongs to the field of chemical reaction devices, wherein the heat-exchangeable stirring shaft comprises a main shaft, a first cavity and a second cavity which are mutually isolated are arranged in the main shaft, and an opening is arranged at one end of the main shaft in each of the first cavity and the second cavity; a first connecting pipe is arranged on the main shaft and communicated with the first cavity, a second connecting pipe is arranged on the main shaft and communicated with the second cavity, and at least one winding pipe is arranged between the first connecting pipe and the second connecting pipe to be communicated; the heat exchange medium is introduced into the inner communicating pipeline area of the reactor, so that the heat exchange inside the reactor can be realized; the structure that the winding pipe is spirally wound around the main shaft realizes the stirring function of the reactant raw materials and pushes one axial end of the reactant raw material main shaft to convey the reactant raw materials; the utility model discloses a rotary motion of stirring post on the main shaft can make more abundant and reactant raw materials of heat transfer pipeline contact, has improved heat exchange efficiency greatly. Above-mentioned utility model though solved the inhomogeneous, the poor problem of heat transfer effect of reactor mixture, it has the material easily to adhere on the (mixing) shaft, leads to the fault shutdown and the extravagant, reactor washing difficulty scheduling problem of material. Moreover, the pipe-winding inside the reactor cannot be guaranteed to be free from shaking, and tends to generate forward or backward driving force on the reaction materials, thereby causing back-mixing.

The invention aims to overcome at least one defect (deficiency) of the prior art and provides a dynamic tangential flow tubular reactor which is used for solving the problems of fault shutdown, material waste and difficult reactor cleaning caused by easy adhesion of materials on a rotating shaft of the reactor.
The technical scheme adopted by the invention is as follows: a dynamic tangential flow tubular reactor comprises a reactor shell, a rotating shaft arranged in the reactor shell, a rotating fixing device used for connecting the rotating shaft and the reactor shell, and a material inlet and material outlet 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 outer wall surface of the rotating shaft; the reactor also comprises a scraper component arranged on the inner wall surface of the reactor shell. The rotating shaft of the reactor rotates to stir the reaction materials and provide a forward driving force for the reaction materials, the reaction materials enter the reaction cavity through the material inlet and outlet assembly, and reaction products come out of the reaction cavity; the stirring column vertical to the rotating shaft can stir the materials in the tangential direction along with the rotation of the rotating shaft, so that the materials are mixed more uniformly, the materials cannot generate forward or backward driving force, and the back mixing phenomenon of the materials is avoided; during the rotation of the rotating shaft, part of the materials are easy to adhere to the rotating shaft due to the self viscosity, and at the moment, the scraper component can scrape the materials adhered to the rotating shaft off and reenter the reaction chamber for mixing reaction. The waste of adhesion material can be avoided in the setting of scraper subassembly, avoids machinery to cause the fault shutdown because of the adhesion, avoids the reaction to finish the back reactor and washs the problem of difficulty.
Furthermore, the scraper components are a plurality of scraper units which are arranged on the inner wall surface of the reactor shell at intervals along the axial direction; the distance between two adjacent scraper units corresponds to the stirring column. Because the stirring column and the scraper unit are both positioned in the reaction cavity, in order to avoid collision between the stirring column and the scraper unit when the stirring column rotates along with the rotating shaft, the scraper unit is arranged at intervals, and the interval part has enough space to accommodate the rotation of the stirring column without collision between the stirring column and the scraper unit; simultaneously, scraper unit can be fine again strike off the adhesion material of axis of rotation under the condition of avoiding bumping with the stirring post.
