    • A heating vessel for concentration is formed in an elongated one, and a baffle plate is arranged to increase sulfuric acid liquid concentration at an outlet to a high level. The heating vessel for concentration and a heating vessel for distillation are installed so that the respective heating vessels have substantially the same waste sulfuric acid liquid level therein, forming continuous flow of the sulfuric acid liquid without presence of a valve or an intermediate tank in a connecting pipe. The heating vessel for distillation is formed in an elongated one with a baffle plate arranged therein to increase the impurity concentration included in concentrated sulfuric acid liquid at an outlet to a high level. In addition, a heater inserted into a heating vessel made of glass is supported at two locations of an inserting portion and a leading portion of the heating vessel formed as a bulged portion, reducing stress concentration to the heater supporting portion due to vibration of the liquid in the heating vessel and vibration of the heating vessel per se.
    • 用于浓缩的加热容器形成为细长的加热容器,并且设置挡板以将出口处的硫酸液体浓度提高到高水平。 用于浓缩的加热容器和用于蒸馏的加热容器被安装成使得各个加热容器在其中具有大致相同的废硫酸液位,在连接中不形成阀或中间罐的情况下形成硫酸液体的连续流动 管。 用于蒸馏的加热容器形成为具有布置在其中的挡板的细长的加热容器,以将出口处的浓硫酸液体中的杂质浓度增加到高水平。 此外,插入到由玻璃制成的加热容器中的加热器被支撑在形成为凸出部分的加热容器的插入部分和引导部分的两个位置处,由于液体的振动而减小了对加热器支撑部分的应力集中 在加热容器和加热容器本身的振动。
