Thin film distillation method

제1도는 본 발명에 사용되는 장치의 부분 단면도.1 is a partial cross-sectional view of a device used in the present invention.

제2도는 본 발명에 의한 장치의 횡단면도.2 is a cross-sectional view of the device according to the invention.

본 발명은 박막증류방법에 관한 것으로서, 더 상세히 설명하면 증류관체내에 압력실을 형성하여 압력실에서 발생하는 증기를 압력차에 의하여 증류관체의 내주벽으로 흐르는 유체에 분사시키므로서 유체가 증류관체의 내주벽에서 박막으로 흐르게한 박막증류방법에 관한 것이다.The present invention relates to a thin film distillation method, and in more detail, a pressure chamber is formed in a distillation tube to inject a vapor generated from the pressure chamber into a fluid flowing into the inner circumferential wall of the distillation tube by a pressure difference. The present invention relates to a thin film distillation method which flows from the inner circumferential wall to a thin film.

박막 증류방법은 원통형의 증류관체 내주벽으로 증류할 유체를 박막상으로 흐르도록 하면서 증류관체를 가열하므로서 유체중의 휘발분을 증류하는 증류방법인바, 종래에는 유체가 증류관체의 내주벽에서 박막으로 흐르도록 하기 위하여 증류관체내에 익편이 부착된 회전축을 장설하여 모우터로 회동되게 하므로서 익편에서 나오는 바람으로 유체가 증류관체 내주벽에 박막으로 흐르도록 하였는바, 이와 같은 종래의 방법에 의하면 증류관체에 모우터를 장설하여야 하므로 기계구성이 복잡하게 되고 모우터가 고장나면 박막이 형성되지 않게 되어 증류효과가 감소되게 되는 결점이 나타났다.The thin film distillation method is a distillation method for distilling volatile components in a fluid by heating a distillation tube while flowing a fluid to be distilled into a cylindrical distillation tube inner circumferential wall, and conventionally, fluid flows from the inner circumference wall of the distillation tube to a thin film. In order to ensure that the rotor is attached to the rotor in the distillation tube to be rotated to the motor, the fluid flows in a thin film on the inner circumferential wall of the distillation tube by the wind coming from the blade, according to the conventional method Since the motor must be installed, the mechanical configuration becomes complicated, and when the motor breaks down, a thin film is not formed and the distillation effect is reduced.

본 발명은 모우터를 사용하지 않고 증류관체에서 발생되는 증기압력으로 증가를 벽면에 분사시켜 유체가 증류 관체 내벽에 박막상태로 흐르도록 하므로서 모우터등의 기계적인 수단을 이용하는 경우보다 기계 구성이 간단하면서 고장율이 적게한 것이다.The present invention is simpler in mechanical construction than in the case of using a mechanical means such as a motor by injecting an increase to the wall surface by the vapor pressure generated in the distillation tube without using a motor to allow the fluid to flow in a thin film state on the inner wall of the distillation tube. The failure rate is low.

즉 본 발명은 증류관체내에 유체가 증류되는 증류실과 분리된 압력실을 형성하여 증류실과 압력실 사이에 압력차가 생기도록 하므로서 압력실에서 발생되는 증기가 압력실보다 저압상태의 증류실로 분사될 때 이를 증류관체의 내주벽으로 분사되도록 하여 유체가 박막상태로 증류관체의 내주벽에 밀착되어 흐르게 하는 것이다.That is, the present invention forms a pressure chamber separate from the distillation chamber in which the fluid is distilled in the distillation tube so that a pressure difference is generated between the distillation chamber and the pressure chamber, so that steam generated in the pressure chamber is injected into the distillation chamber at a lower pressure than the pressure chamber. This causes the fluid to be injected into the inner circumferential wall of the distillation tube so that the fluid flows in close contact with the inner circumferential wall of the distillation tube.

본원 발명에서 압력실의 증기를 증류관체의 내주벽으로 분사시킬 때는 증류관체 내주벽에 대하여 직각으로 분사되도록 하는 것보다 경사지게 분사되도록 하는 것이 유체를 박막 상태로 밀착되어 흐르게 하는데 더 효과적이다.In the present invention, when injecting the steam in the pressure chamber to the inner circumferential wall of the distillation tube, it is more effective to inject the fluid in a thin film state than to be injected at a right angle to the inner circumferential wall of the distillation tube.

압력실과 증류실은 증류할 유체의 종류에 따라 다단식으로 하거나 일단으로 형성할 수 있는바, 다단식의 경우는 격판으로 상하 증류실을 분리하여 하부 증류실이 상부증류실에 대한 압력실의 역할을 하도록 한다.The pressure chamber and the distillation chamber can be formed in multiple stages or in one stage according to the type of fluid to be distilled. In the case of multiple stages, the upper and lower distillation chambers are separated by a diaphragm so that the lower distillation chamber serves as a pressure chamber for the upper distillation chamber. .

이하 본 발명을 첨부도면에 의하여 구체적으로 설명하면 외측에 가열기(도시하지 않았음)을 장설하게 된 증류관동체(1)의 내측에 중앙공(2')이 형성되고 주연부가 하향 경사진 격판(2)을 장설하여 압력실(A)과 증류실(B)을 분리시키고 격판(2)의 중앙공(2') 상방에 증기안내판(4)에 의하여 증기안내공(5)이 측벽에 형성된 증기유도구(5)를 착설한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, in which a central hole 2 'is formed inside the distillation tube 1 in which a heater (not shown) is installed on the outside, and the periphery of the diaphragm is inclined downward ( 2) to install the pressure chamber (A) and the distillation chamber (B), and the steam guide hole (5) formed on the side wall by the steam guide plate 4 above the central hole (2 ') of the diaphragm (2) The guide port 5 is installed.

증류할 유체(6)은 증류관본체(1)의 내주벽을 따라 하향 유동하면서 동체외주벽에 장설된 가열기로 가열하면 유체중의 저비점 물질이 증발되는바, 이때 기체 하부에서 증기가 발생하면 압력실(A)에 증기압이 발생하게 되고 압력실(A)에서 발생한 증기는 증기 압력에 의하여 격판(2)의 중앙공(2')와 안내판(4)에 의하여 형성되는 증기안내공(5)을 통하여 동체(1)의 내주벽으로 경사지게 분사되면서 동체주벽을 따라 흘러내리는 유체를 확산시켜 유체가 동체 주벽에서 박막상태로 되어 흘러내리도록 한다.When the fluid 6 to be distilled flows downward along the inner circumferential wall of the distillation tube body 1 and is heated by a heater installed in the outer circumferential wall of the body, low boiling point substances in the fluid evaporate. The steam pressure is generated in the chamber A, and the steam generated in the pressure chamber A causes the steam guide hole 5 formed by the central hole 2 'of the diaphragm 2 and the guide plate 4 by the steam pressure. While injecting inclined to the inner circumferential wall of the body 1 through the diffusion of the fluid flowing along the body circumferential wall so that the fluid flows in the form of a thin film on the body circumferential wall.

상기와 같은 본 발명에 의하면 증류관내에서 발생하는 증기압력으로 유체를 박막으로 되게 확산시키므로 모우터나 기타 기계적인 유체 확산장치가 불필요하게 되어 기계적인 고장이 적고 기계의 구성을 간단하게 할 수 있다.According to the present invention as described above, since the fluid is diffused into a thin film by the vapor pressure generated in the distillation tube, a motor or other mechanical fluid diffusion device becomes unnecessary, so that there is little mechanical failure and the configuration of the machine can be simplified.

또한 본 발명에 의하면 압력실에서 분사되는 증기에 함유된 비말들이 유체와 접촉시 유체에 흡수되므로 증기와 함께 비말이 배출되는 것을 방지할 수 있다.Further, according to the present invention, since the droplets contained in the steam injected from the pressure chamber are absorbed by the fluid when in contact with the fluid, it is possible to prevent the droplets from being discharged together with the steam.

Claims
