摘要：
In an apparatus capable of distilling and refining an easily polymerizable substance, piping is performed so that when a strainer in action is switched to a backup strainer, the strainer can be switched after removing the air in the backup strainer to replace the air in the backup strainer to a discharge liquid of a pump. According to the apparatus, switching the strainers installed on the upstream side of the pump for extracting a liquid of a vacuum distillation column which distills and refines the easily polymerizable substance can be performed with no trouble in the operation of the distillation column. When the apparatus comprises a means measuring a differential pressure between the upstream side and the downstream side of the strainer in action, the two or more strainers installed in parallel can be switched at proper times and the easily polymerizable substance can be produced efficiently.
摘要（中）：
在能够蒸馏和精炼易聚合物质的装置中，进行配管，使得当将过滤器动作切换到备用过滤器时，可以在除去备用过滤器中的空气以更换备用空气中之后切换过滤器 过滤器到泵的排出液体。 根据该装置，在蒸馏塔的运转中，不需要麻烦地切换安装在泵的上游侧的用于提取真空蒸馏塔的液体的过滤器，该真空蒸馏塔的蒸馏和精制可容易聚合的物质。 当该装置包括测量过滤器的上游侧和下游侧之间的压差的装置时，可以适当地切换并联安装的两个或更多个过滤器，并且可以有效地生产易于聚合的物质。
