摘要： The invention relates to a method and a device for the production of pure steam. A falling-film evaporator is used. Of the water-steam mixture leaving the evaporator unit, part of the water is collected at the bottom of the device, and a fraction mainly consisting of steam enters a rising spiral channel for the separation of impurities. In the periphery of the spiral channel apertures are provided for separating impurity-containing droplets, which condense on a surface outside the apertures. The liquid formed is removed from the device. The water phase collected at the bottom enters a recycle line connected to the feed end of the evaporator unit. Feed water is supplied to the recycle line to compensate for pure steam consumption.

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.
