1. A purification method for water polluted with accompanying substances in a purification system, comprising:
an option for supplying polluted water; a pumping device; a condensation region; a collection receptacle; a heating device; a water distributor; a humidifier; a first line by which the polluted water can be delivered to the condensation region, the heating device and the humidifier by way of the pumping device; a line by which the condensation region is connected to the collection receptacle; and a flow channel, which at least connects the humidifier and the condensation region to each other; a blower; and a control device, wherein the aforementioned installations interact with each other in such a way that: the polluted water is supplied to the condensation region by way of the pumping device, whereby the surface temperature of the same adapts to the media temperature of the polluted water; the polluted water takes up amounts of heat when flowing through the condensation region; the polluted water subsequently flows through a heating device, where it takes up additional amounts of heat, wherein: the polluted water circulating in the first line is heated beyond the intrinsic temperature thereof in the heating device so that it has an increased evaporation tendency when entering the humidifier; the polluted water is subsequently delivered to the humidifier and distributed, and comes in close contact with an air flow, whereby it at least partially evaporates; an air flow forms in the flow channel, which flows through the humidifier and is loaded with an evaporating fraction of the polluted water; the loaded air flow flows through the condensation region and is subsequently returned in the flow channel to the humidifier, wherein the condensation region has a lower temperature than the air flow so that purified liquid is able to condense out, and the same is collected and returned via a line to the collection receptacle, wherein the temperature of the polluted water flowing in the first line section at a minimum corresponds to the temperature of the supplied polluted water at the inlet of the condensation region, and at a maximum corresponds to the boiling temperature of the same at the outlet of the heating device, wherein; the control device controls the purification method in such that the largest possible amount of purified water per unit of time is ascertained from measured variables ascertained in the purification system, and that the flow velocity of the air flow required for this purpose is set. |
