example 1

[0041] According to Example 1 of the present invention, the agitating device 130 includes three agitators 133, 134 and 135, but when at least two agitators are positioned at regular intervals along the height direction of the rotating shaft 132 to form a batch type with a multi-stage structure In the case of a reactor, the number of stirrers is not particularly limited. It is important that the batch reaction process produces a uniform product, and the agitators 133, 134, and 135 according to Example 1 of the present invention are positioned at regular intervals along the height direction of the rotation axis 132 to form a multi-stage structure, therefore, unlike having a single Compared with the primary structure of the agitator, the reactants can be stirred effectively, and the flow of the reactants in each area can be kept uniform. Therefore, a uniform product can be finally produced, thereby increasing productivity and improving stability of product quality.

Abstract

Embodiments of the present invention provide a batch reactor for maintaining optimal flow performance and temperature-control performance at industrial sites through a double pipe-type baffle structure and a multi-stage structure by means of a plurality of agitators. The batch reactor according to one embodiment of the present invention comprises a cylindrical reactor main body; an agitation device; a discharge nozzle; and a baffle positioned in the circumferential direction of the reactor main body between the inner wall of the reactor main body and the agitation device, wherein the agitation device includes at least two agitators and one rotary shaft, the baffle includes at least two pipes, and the pipes are separated from each other and positioned in a line in the radial direction of the reactor main body.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2018-0108360 filed with the Korean Intellectual Property Office on September 11, 2018, the entire contents of which are hereby incorporated by reference. technical field [0003] This invention relates to batch reactors, and more particularly to batch reactors with baffles. Background technique [0004] A typical batch reactor includes: a reactor body containing reactants; a stirrer installed inside the reactor body to stir the reactants; and a driving motor to rotate the stirrer. [0005] Typically, batch exothermic reaction processes require proper control of the internal temperature of the reaction chamber to produce uniform products, increase productivity, and improve product quality stability. Accordingly, the batch reactor may include a reactor jacket, baffles, a reflux condenser, and the like as constituent elements for controlling the tem...
