Abstract
Abstract A process for purifying liquids comprises the steps of feeding the liquid to be purified into a sealed chamber and to guide the liquid in such a relation to a stream of air which is guided to circulate in a cycle in said chamber and is heated during part of its cycle, that the liquid will come into contact with the stream of air in a location where said stream of air has a raised temperature, bringing the damped air thus generated to condensate and discharging the resulting condensate from said chamber such as through a first line whereas the rest of the liquid is discharged separately through a second line. The invention also refers to a plant or device, designed to carry out the process.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
114 words
A process for purifying a liquid, preferably water, comprising the steps of: (a) providing a sealed chamber, (b) providing a source of heat and motive power within said chamber, (c) forcing air under control of said source over said source to heat said air, (d) providing a cooling chamber and cooling said cooling chamber under control of said source, (e) guiding said liquid through said cooling chamber to cool same, (f) spraying said cooled liquid in a spraying area in said sealed chamber, (g) passing said heated air through said spraying area to collect liquid, and (h) passing said thusly damped air through said cooling chamber to condense out said collected and purified liquid.
Claim 2
Dependent Claim
114 words
A process for purifying a liquid, preferably water, comprising the steps of: (a) providing a sealed chamber, (b) providing a source of heat and motive power within said chamber, (c) forcing air under control of said source over said source to heat said air, (d) providing a cooling chamber and cooling said cooling chamber under control of said source, (e) guiding said liquid through said cooling chamber to cool same, (f) spraying said cooled liquid in a spraying area in said sealed chamber, (g) passing said heated air through said spraying area to collect liquid, and (h) passing said thusly damped air through said cooling chamber to condense out said collected and purified liquid.
Claim 3
Independent Claim
183 words
A system for purifying a liquid, preferably water, which comprises: (a) a sealed chamber, (b) motive and heat means positioned in said chamber for providing motive power and heat, (c) forcing means responsive to said motive and heat means for forcing air in said chamber over said motive and heat means to heat said air, (d) a cooling chamber in said sealed chamber, (e) means controlled by said motive and heat means to cool said cooling chamber, (f) feed means entering said sealed chamber and passing through said cooling chamber for passing said liquid through said cooling chamber to cool said liquid, (g) a spray area in said sealed chamber, (h) spraying means in said spray area, coupled to said feed means for spraying said cooled liquid in said spray area, said forcing means forcing said heated air through said spray chamber, whereby said air collects liquid in said spray chamber, (i) conduit means directing said thusly damped air from said spray chamber to said cooling chamber wherein said collected liquid is condensed, and (j) outlet means for removing collected and purified liquid.
