関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a novel apparatus used for separating a specific liquid component from a liquid mixture by a pervaporation method.

的に気化ガス室に透過させ、これを気化状態で取り出す
分離法である。[Prior Art] The pervaporation method is also called a pervaporation separation method, and it is effective for removing liquid components from a liquid mixture such as a mixture of two or more kinds of organic liquids, a mixture of water and an organic liquid, a solution of an organic compound or the like. Research is being actively conducted as a separation method.
This method is a method for separating a specific liquid component from a liquid mixture using a separation membrane, and a separation tank in which a liquid chamber for supplying the liquid mixture to be treated and a vaporized gas chamber are present through the separation membrane. It is a separation method in which the vaporized gas chamber is evacuated or depressurized to preferentially permeate a specific liquid component from the liquid mixture into the vaporized gas chamber due to the separation characteristics of the separation membrane, and the vaporized state is taken out.
上記方法において、気化ガス室で発生する液体成分の気
化ガスは、一般に、凝縮させて液状で回収するため、分
離槽の気化ガス室は凝縮器を経て気液分離器に接続され
る。In the above method, since the vaporized gas of the liquid component generated in the vaporized gas chamber is generally condensed and recovered in a liquid state, the vaporized gas chamber of the separation tank is connected to the gas-liquid separator via the condenser.

くこともある。[Problems to be solved by the invention] However, when the condenser and the gas-liquid separator are simply arranged on the horizontal floor in the vaporized gas chamber of the separation tank, the rising part is connected to the pipe connected to the condenser and the gas-liquid separator. Exists. for that reason,
A part of the vaporized gas flowing through the pipe comes into contact with the pipe wall, and the condensate that is generated accumulates in the pipe, increasing the flow resistance in the pipe, so that when the vaporized gas chamber is decompressed by the decompression pump, the vaporization occurs. There is a problem that the degree of vacuum in the gas chamber cannot be raised sufficiently and the separation speed is reduced. Also, in some cases, the condensate accumulates or stays and pulsates to cause pressure fluctuations, the condensate flows back into the separation tank, and the effective area of the separation membrane is reduced to reduce the separation speed. It may be invited.
かかる問題は、液室内の温度を上げて分離膜表面での蒸
発速度を高めることにより、分離特性を改善しようとし
た場合、前記管壁での凝縮液量が多く、しかもガス流量
も多いため、特に深刻である。Such a problem is that when the temperature in the liquid chamber is increased to increase the evaporation rate on the surface of the separation membrane to improve the separation characteristics, the amount of condensed liquid on the pipe wall is large and the gas flow rate is also large. Especially serious.
また、上記問題に対して、配管を全て保温し、気化ガス
の凝縮を防止する方法も考えられるが、保温設備を別途
必要とすると共に保温のためのエネルギーが必要とな
り、工業的な実施において、極めて不利となる。In addition, for the above problems, a method of keeping all the pipes warm and preventing condensation of vaporized gas is also conceivable, but energy for keeping warm is required together with a separate warming facility, and in industrial implementation, It is extremely disadvantageous.
