Device for the recovery of a processed liquid in the form of a condensate on a liquid to be processed

Distillation device for purification of water by evaporating water to be treated and by condensing purified water, said device comprising:

• first and second distributing and guide means vertically disposed in at least one chamber;
• said distributing and guide means consisting of sheets of a wettable material in a form selected from the group consisting of woven cloth and fibrous nonwoven material, said sheets being capable of carrying a film of water on surface sides and forming flow regions;
• said distributing and guide means being disposed in said chamber such that at least one flow region of a first distributing and guide means is neighbored to at least one flow region of a second distributing and guide means;
• means for developing a flow of said water to be treated along said flow region of said first distributing and guide means;
• means for developing a flow of purified water on the flow region of said second distributing and guide means;
• means for controlling the temperature of the flow of water so that the flow of water on the second distrubuting and guide means is cooler in temperature than the flow of water to be treated on the first distributing and guide means;
• each sheet of wettable material being fastened on its upper and lower ends by being clamped between upper and lower pairs of plates;
• said means for developing said flow of said water to be treated along said first distributing and guide means and said means for developing said flow of purified water along said second distributing and guide means comprising an upper distributing chamber for distributing the water across said first and second distributing and guide means and a lower collecting chamber for collecting the water from said first and second distributing and guide means and for carrying off the water from said guide means;
• each said distributing chamber and each said collecting chamber being formed between the plates of each upper and lower plate pair.

Distillation device for purification of water by evaporating water to be treated and by condensing purified water, said device comprising:

• first and second distributing and guide means vertically disposed in at least one chamber;
• said distributing and guide means being formed by sheets of a wettable flat material and being adapted to carry a film of water on surface sides and to form flow regions;
• said distributing and guide means being disposed in said chamber such that at least one flow region of a first distributing and guide means is neighbored to at least one flow region of a second distributing and guide means;
• means for developing a flow of said water to be treated along said flow region of said first distributing and guide means;
• means for developing a flow of purified water on the flow region of said second distributing and guide means;
• means for controlling the temperature of the flow of water so that the flow of water on the second distributing and guide means is cooler in temperature than the flow of water to be treated on the first distributing and guide means;
• each sheet of wettable material being fastened on its upper and lower end between upper and lower pairs of plates;
• said means for developing said flow of said water to be treated along said first distributing and guide means and said means for developing said flow of purified water along said second distributing and guide means comprising an upper distributing chamber for distributing the water across said first and second distributing and guide means and a lower collecting chamber for collecting the water from said first and second distributing and guide means and for carrying off the water from said guide means;
• each said distributing chamber and each said collecting chamber being formed between the plates of each upper and lower plate pair;
• said upper and lower plates each having at least two holes, of which first holes in the upper plates form a channel intersecting the distributing chambers for delivery of said water to be treated and second holes form a channel intersecting said chambers for delivery of the purified water, and of which first holes in the lower plates form a channel intersecting said collecting chambers for carrying off said water to be treated and second holes form a channel intersecting said collecting chambers for carrying off the purified water;
• at said at least one first flow region for said water to be treated the second hole in the respective upper plate and the second hole in the respective lower plate being closed off by seals from the distributing chamber and the collection chamber respectively;
• and
• at said at least one second flow region for the purified water the first holes in the upper and lower plates being sealed off by seals from the distributing chamber and the collection chamber respectively.

Distillation device for purification of water by evaporating water to be treated and by condensing purified water, said device comprising:

• a plurality of chambers and first and second distributing and guide means vertically disposed in each of said chambers;
• said distributing and guide means being formed by sheets of a wettable material in a form selected from the group consisting of woven cloth and fibrous nonwoven material, said sheets being capable of carrying a film of water on surface sides and forming flow regions;
• said distributing and guide means being disposed in said chambers such that at least one flow region of a first distributing and guide means is neighbored to at least one flow region of a second distributing and guide means;
• means for developing a flow of said water to be treated along said flow region of said first distributing and guide means;
• means for developing a flow of purified water on the flow region of said second distributing and guide means;
• means for controlling the temperature of the flow of water so that the flow of water on the second distributing and guide means is cooler in temperature than the flow of water to be treated on the first distributing and guide means;
• said chambers with said flow regions formed on said first distributing and guide means and with the flow regions formed on said second distributing and guide means following one another in cascade-like manner such that said water to be treated and the purified water flow successively through all chambers in opposed directions;
• each sheet of wettable material being fastened at its upper edge between two upper plates and at its lower edge between two lower plates, the upper and lower plates being adjustable relative to one another for tensioning the sheets of wettable material.
