与此设施连续提纯含溶剂的排气具有两个相同串联连接的接收塔（1），每个具有至少一个微波发生器（13）和一个共同的真空蒸镀装置在两个阶段中进行。 在清洁阶段，排出的空气通过第一接收塔传递，其特征在于，由低极性物质在封闭的蒸发器容器（3）的排出空气，优选容纳记录（5）将溶剂除去装置和清洁空气进入大气中。 一旦接收装置（5）的饱和的，被切换到再生阶段，其中所述第二接收塔（1）引导，并且所述第一接收塔（1）真空蒸镀设备，和相关联的微波发生器（13），同时排出空气被接通。 在主机（1）从塔低温蒸发被隔离设置蒸发器容器（3），所述溶剂，然后冷凝在冷凝器和收集在收集容器（20），可重复使用的溶剂中。 第一接收塔（1）或第二接收塔的清洗阶段的再生阶段完成后（1）重复描述的操作，等等。

With this facility for continuously purifying solvent-containing exhaust air is worked with in each case at least one microwave generator (13) and a common vacuum evaporation device in two phases with two identical series-connected absorption towers (1). In a cleaning phase, the exhaust air is passed through a first absorption tower in which the exhaust air in a closed evaporator container (3) through a low polarity substances preferably accommodates recording means (5) the solvents are removed and clean air going to the atmosphere. Once the receiving means (5) is saturated, is switched into a regeneration phase, in which the exhaust air through the second absorption tower (1) guided at the same time and the first receiving tower (1) a vacuum evaporation device, and the associated microwave generator (13) are switched on. At low temperature to evaporate from the absorption in the tower (1) is isolated arranged evaporator container (3) and condense the solvent then in the condenser and will collect as a reusable solvent in a collecting vessel (20). After completion of the regeneration phase of the first receiving tower (1) or the cleaning phase of the second intake tower (1) is repeated so the procedure described
