Batch reactor with baffle

A technology of reactors and spoilers, applied in mixers with rotary stirring devices, chemical/physical/physical-chemical stationary reactors, detailed information of chemical/physical/physical-chemical reactors, etc., can solve the problem of stirring paddles. The blade size cannot be increased, the temperature control performance of the spoiler is deteriorated, and the heat transfer area of ​​the spoiler is reduced, so as to improve the eddy current and mixing performance.

Problems solved by technology

[0004] However, depending on the installation form of the turbulence, there is a limit to the size of the stirring blade and the expansion of the surface area (heat transfer area) of the turbulence
For example, when the spoiler occupies a long area in the radial direction of the reactor main body, the size of the stirring blade cannot be increased, and accordingly the stirring performance of the reactants and the reaction performance cannot be infinitely improved
In addition, as the reactor size increases, the heat transfer area of ​​the spoiler decreases relative to the volume of a reactor with the same spoiler structure, and accordingly, the temperature control performance of the spoiler deteriorates

Abstract

Provided is a batch reactor with an improved baffle installation structure. The batch reactor comprises: a reactor body for holding a reactant; a stirring blade, installed inside the reactor body, for stirring the reactant; a motor, coupled to the rotation shaft of the stirring blade, for rotating the stirring blade; and a plurality of baffles which are located between the inner wall of the reactor body and the stirring blade and installed at a distance from each other along the circumferential direction of the reactor body. Each of the plurality of baffles includes a plurality of pipes disposed to be adjacent to each other along the radial direction and the circumferential direction of the reactor body.

Description

technical field [0001] The present invention relates to a batch reactor. More particularly, the present invention relates to a spoiler mounting structure. Background technique [0002] A typical batch reactor includes a reactor body for containing reactants, a stirring blade provided in the reactor body to stir the reactants, and a drive motor to rotate the stirring blade. In addition, the batch reactor may include a reactor jacket, a turbulence device, and a reflux condenser as constituent elements for controlling the temperature of reactants. [0003] Turbulators are provided as tubes through which fluid flows for heat exchange, and are arranged away from the outside of the stirring blades and close to the inner wall of the reactor body. The turbulence changes the flow of the reactant in the vertical direction due to the rotation of the stirring blade to fully mix the reactant, and provides temperature control (that is, heat control) performance to maintain the reactant ...
