혼합 능력이 개선된 회분식 반응기{A Batch Reactor for Improving Mixing Capability}[0001] The present invention relates to a batch reactor having improved mixing ability,

본 발명은 혼합 능력이 개선된 회분식 반응기에 관한 것이다.The present invention relates to a batch reactor with improved mixing capability.

회분식 반응기는 배치형 반응기(Batch Reactor)로도 불리며, 소규모 운전이나 새로운 공정의 시험, 고가의 생성물 제조 및 연속 공정으로 전화하기 어려운 공정들에 대하여 사용되고 있다.Batch reactors are also referred to as batch reactors and are used for processes that are difficult to call by small operation or testing of new processes, production of expensive products and continuous processes.

이러한 회분식 반응기는 교반을 통하여 반응물들을 혼합하는데, 원심력 등에 의하여 반응기의 내부와 외부의 혼합이 어렵다는 문제가 있다.Such a batch reactor mixes the reactants through stirring, and there is a problem that it is difficult to mix the inside and the outside of the reactor by centrifugal force or the like.

이러한 문제점을 해결하기 위하여, 종래에는 배플(Baffle)을 반응기의 벽면과 수직인 방향으로 판형 형태로 설치하여, Vortex형성을 완화하고, 내부 혼합 증대를 꾀하였으나, 혼합능력의 개선이 미미하다는 문제점이 있었다.In order to solve such a problem, conventionally, a baffle is provided in a plate shape in a direction perpendicular to the wall surface of the reactor to alleviate the formation of the vortex and to increase the internal mixing. However, there was.

이에, 회분식 반응기의 내부에 설치되는 배플을 이용하여 종래 기술의 배플에 비하여 반응액의 내부 혼합능력이 더욱 개선된 새로운 회분식 반응기에 대한 연구가 필요한 실정이다.
Therefore, it is necessary to study a new batch reactor in which the internal mixing ability of the reaction liquid is further improved as compared with the baffles of the prior art by using the baffles installed inside the batch reactor.

본 발명은 도 1과 같이, 반응기 내의 하부에 설치되어 반응기 내부의 반응액을 교반하는 교반기; 및 반응기 내의 벽면을 따라서 나선형을 이루며 설치된 배플(Baffle)을 포함하는 회분식(Batch) 반응기를 제공한다. 종래의 기술에서는 배플(Baffle)이 반응기의 벽면과 수직인 방향으로 판형 형태로 존재했으나, 본 발명의 회분식 반응기는 도 1에서와 같이, 배플이 반응기 내의 벽면을 따라서 나선형을 이루며 설치되어 있기 때문에, 교반기에 의하여 반응액을 교반 시킬 때, 반응액이 나선형의 배플을 따라 상승 또는 하강하기 때문에, 그 혼합능력을 개선할 수 있다.
As shown in FIG. 1, the present invention relates to an apparatus for separating and purifying a reaction mixture, comprising: a stirrer provided at a lower portion of the reactor for stirring a reaction solution inside the reactor; And a baffle provided in a spiral shape along a wall surface in the reactor. In the prior art, the baffle was present in a plate shape in a direction perpendicular to the wall surface of the reactor. However, since the baffle of the present invention is installed in a spiral shape along the wall surface in the reactor as in Fig. 1, When the reaction liquid is stirred by the stirrer, the reaction liquid is raised or lowered along the spiral baffle, so that the mixing ability can be improved.

본 발명의 회분식(Batch) 반응기에 있어서, 상기 배플은 일정한 각도의 나선형을 이루며 설치될 수 있다. 또한, 상기 배플은 도 2에서와 같이 배플간의 거리 및 반응기의 직경을 정의하는 경우, 배플간의 거리(pitch)가 반응기의 직경 대비 1/2 내지 3/4를 만족할 때, 그 혼합능력이 더욱 개선될 수 있다.

In the batch reactor of the present invention, the baffle is installed in a spiral shape at an angle along the wall surface in the reactor. The constant angle refers to the angle formed by the baffle with respect to the horizontal plane of the wall in the reactor, and can be variously adjusted according to the user's intention.

본 발명의 회분식(Batch) 반응기에 있어서, 상기 반응기는 특별한 제한이 있는 것은 아니나, 바람직하게는 원형일 수 있다. 반응기가 원형인 경우, 반응기 내의 벽면의 수평에 대하여 배플이 이루고 있는 각도가 일정하게 될 수 있으며, 반응기 내의 전체 반응액의 혼합능력이 더욱 개선될 수 있다.
In the batch reactor of the present invention, the reactor is not particularly limited, but may be preferably circular. When the reactor is circular, the angle formed by the baffle with respect to the horizontal plane of the wall in the reactor can be made constant, and the mixing ability of the entire reaction liquid in the reactor can be further improved.

본 발명의 회분식(Batch) 반응기에 있어서, 상기 배플의 너비는 도 3에서와 같이 나타낼 수 있으며, 상기 배플의 너비는 사용자의 의도에 따라서 다양하게 조절될 수 있으나, 바람직하게는 반응기 직경의 1/8 내지 1/6인 것을 사용할 수 있다.
In the batch reactor of the present invention, the width of the baffle may be as shown in FIG. 3, and the width of the baffle may be variously adjusted according to the user's intention, 8 to 1/6 can be used.
