A liquid cleaning device comprises a vessel (1), a bottom plate (3), a heating device and a tubular riser (12) arranged in the vessel for heated liquid ascending through the riser, the heated liquid from the upper, open end of the riser running back through force of gravity down and outside of the riser to be reheated and ascend agains through the riser, and so on. The vessel--61) is cylindrical and substantially its entire base (17) can be heated by means of the heating device (171). A plurality of discs (51-54) of equal size are arranged in the upper part of the vessel ( 1), said discs having a central aperture (510) for the riser (12) and a plurality of small holes (511) distributed uniformly across the entire surface of the discs and provided with drip edges (5110). A distributor (14) is arranged at the upper, open end of the riser (12) to distribute the hot liquid coming out of the ruser uniformly over the uppermost disc (51).

The invention claimed is: 1. A liquid cleaning device intended for purifying liquid from pollutants and comprising a vessel (1) for the liquid, a bottom plate (3), a heating device and a tubular riser (12) arranged centrally in the vessel (1) for heated liquid ascending through the riser, the heated liquid from the upper, open end of the riser (12) running back through force of gravity down and outside of the riser to be reheated and ascend again through the riser, and so on, characterized in that the vessel (1) is cylindrical and substantially its entire base (17) is configured to be heated by means of the heating device (171); in that a plurality of discs (51-54) of equal size are arranged in the upper part of the vessel, said discs having a central aperture (510) for the riser (12) and a plurality of small holes (511) distributed uniformly across the entire surface of the discs and provided with drip edges (5110); and in that a distributor (14) is arranged at the upper, open end of the riser (12) to distribute the hot liquid coming out of the riser uniformly over the uppermost disc (51). 2. A liquid cleaning device as claimed in claim 1, characterized in that the diameter of the discs (51-54) is approximately equal to the inner diameter of the cylindrical vessel ( 1); in that each of the discs are arranged in a plane, each plane being substantially parallel to the plane of the other discs; in that the distance between the discs is about 9 mm; and in that the small holes in the discs (51-54) have a diameter of about 2-4 mm. 3. A liquid cleaning device for purifying a liquid from pollutants, the device comprising: a cylindrical vessel for holding the liquid, the vessel having an upper portion and a lower portion, the lower portion arranged to contain a portion of the liquid; a heating device located in the lower portion of the cylindrical vessel and configured to heat the portion of the liquid in the lower portion of the vessel; a plurality of discs of substantially equal diameter arranged in the upper portion of the cylindrical vessel and having a diameter approximately equal to the inner diameter of the upper portion of the cylindrical vessel, the plurality of discs having a plurality of holes distributed uniformly across the surface of the discs, the holes having drip edges; a tubular riser arranged centrally in the vessel, the tubular riser extending from the lower portion of the cylindrical vessel and through the plurality of discs, the riser configured for liquid heated by the heating device to ascend through the riser from the lower portion to an upper, open end of the tubular riser; and a distributor arranged at the upper, open end of the riser to distribute the heated liquid uniformly over an uppermost disc of the plurality of discs, the liquid passing through the plurality of holes through force of gravity to be reheated and to ascend again through the riser. 4. The liquid cleaning device of claim 3, wherein the diameter of the discs is approximately equal to the inner diameter of the cylindrical vessel and each of the discs are arranged in a plane, each plane being substantially parallel to the plane of the other discs; the distance between the discs being about 9 mm and the small holes in the discs have a diameter of about 2-4 mm. 5. The liquid cleaning device of claim 3, wherein each of the discs are arranged in a plane, each plane being substantially parallel to the plane of the other discs. 6. The liquid cleaning device of claim 3, wherein the lower portion of the cylindrical vessel comprises a dome of insulating material. 7. The liquid cleaning device of claim 6, wherein the dome includes a valve configured to allow water into the lower portion of the vessel and preventing steam from passing out of the lower portion through the valve. 8. The liquid cleaning device of claim 6, wherein the dome is arched in shape, such that, at a time when the liquid in the lower portion is heated, gas bubbles gather towards the tubular riser. 9. The liquid cleaning device of claim 3, wherein the heating device is substantially flat. 10. A liquid cleaning device comprising: a cylindrical vessel for holding the liquid, the vessel having an upper portion and a lower portion, the lower portion arranged to contain a portion of the liquid; means, located in the lower portion of the cylindrical vessel, for heating the portion of the liquid in the lower portion of the vessel; a plurality of discs of substantially equal diameter arranged in the upper portion of the cylindrical vessel and having a diameter approximately equal to the inner diameter of the upper portion of the cylindrical vessel, the plurality of discs having a plurality of holes distributed uniformly across the surface of the discs, the holes having drip edges; means, arranged centrally in the vessel and extending from the lower portion of the cylindrical vessel and through the plurality of discs, for transporting heated liquid from the lower portion to an upper, open end of the means for transporting liquid; and means, arranged at the upper open end of the means for transporting heated liquid, for distributing the heated liquid uniformly over an uppermost disc of the plurality of discs, the liquid passing through the plurality of holes through force of gravity to be reheated and to ascend again through the means for transporting liquid. 11. The liquid cleaning device of claim 10, wherein the lower portion of the cylindrical vessel comprises a dome of insulating material. 12.
