Abstract

The invention discloses a tower type continuous flow reactor and application thereof. The tower type continuous flow reactor is characterized in that amotor is arranged at the top of the reactor, and is connected with a stirring shaft, the interior of the reactor is divided into a plurality of reaction chambers by partition plates, a plurality of liquid lifting holes and a shaft hole are formed in the partition plate, the stirring shaft extends to the bottom of the reactor through the shaft hole, a liquid sequentially passes through each reaction chamber of the reactor from bottom to top through the liquid lifting holes in the partition plate for reaction, in the reactor, each reaction chamber is internally provided with a layer of stirring blades, all the stirring blades are connected to the same stirring shaft, the motor drives the stirring shaft to rotate, then the stirring shaft drives the stirring blades to rotate, each reaction chamber is internally provided with a coil pipe heat exchanger, and the reaction temperature in each reaction chamber can be independently controlled. The device disclosed by the invention is small in occupied area, relatively low in cost and convenient to regulate and control, and can be applied to continuous production occasions of various reactions.

Description

technical field [0001] The application relates to the field of chemical equipment, in particular to a tower continuous flow reactor and its application. Background technique [0002] In the actual chemical production process, the continuous flow reactor can make the reaction continue and the production process is uninterrupted. However, the traditional stirred reactor has problems such as uneven stirring, insufficient reaction, poor material fluidity, and reaction dead zone. [0003] In response to the above problems, Li Fuqing et al. disclosed a stirred multi-stage horizontal reactor (application number: 201720822643.3). The reactor is equipped with multiple upper baffles and lower baffles, and the baffles divide the reactor into multiple reactors. Each reaction section is equipped with a stirrer, which can react under normal pressure and high pressure conditions, and there will be no back-mixing problems that are easy to occur in traditional reactors; Li Enduan discloses ...
