Industrial evaporator

Abstract

The problem to be solved by the present invention is to specifically disclose an industrial evaporating device, which makes the liquid containing a substance with a lower boiling point than the liquid flow down the outer surface of the guide, and evaporates the low-boiling substance during this process. The device can make the liquid evaporated and processed stably for a long time on an industrial scale of more than 1 ton per hour; further specifically discloses an industrial evaporation device that does not cause denaturation problems due to a part of the liquid staying for a long time. By providing an industrial evaporating device in which the guide itself has no heating source, and a flow path control member is provided in the liquid supply area, the flow path control member has a function to make the flow of the liquid supplied from the liquid receiving port to the porous plate mainly flow from the porous plate. The function of the peripheral part of the plate to flow in the direction of the central part, and the distance K (cm) between the guider and the inner wall surface closest to the inner wall surface of the side shell of the evaporation area satisfies the formula (6) and has the formula (1) To formula (5), or formula (1) to formula (11), or formula (1) to formula (14) specific structure of the industrial evaporation device, can solve the above problems, and easily obtain high-quality, high-purity Concentrated liquids, condensation polymers, thermoplastic polymers, thereby completing the present invention.

Description

technical field [0001] The present invention relates to a new industrial evaporation device. More specifically, it relates to a device for causing a liquid containing a substance having a lower boiling point than the liquid to flow downward along the outer surface of a guide which itself has no heating source, during which the substance having a lower boiling point is evaporated. Background technique [0002] Various devices are known as industrial evaporators for evaporating and removing volatile components and / or low boiling point components in a liquid and concentrating the liquid. For example, in the 6th edition of Handbook of Chemical Engineering (refer to Non-Patent Document 1: 6th Edition, Handbook of Chemical Engineering, pages 403-405, edited by the Society of Chemical Engineering, 1999), it is described that the submerged combustion method and the natural circulation type immersion tube Type, natural circulation horizontal tube type, vertical short tube type, vert...

Problems solved by technology

Therefore, since the high-viscosity material supplied from the high-viscosity material supply port (7) stays in the "dead space" between the porous plate (3) and the inner side wall surface of the hollow body for a long time, the above-mentioned problems inevitably arise.

In addition, even in the recently proposed patent document 8, there is no proposal at all to reduce the "dead space" in the distribution pipe 3 (Fig. 2) and the supply area (Fig. 3a) to the perforated plate.
