System and method for water purification using a solar collector

摘要

The invention relates to a water purification system having at least one solar collector (1) operating an evaporator (2) and a condenser (5) for the evaporated, purified water. The solar collector (1) comprises an absorber (7) for the solar radiation, enclosed from bottom to top in a transparent housing (8), and a metal pipe (9) connected in a heat-conductive manner to the absorber (7) extending in the longitudinal direction of the housing, said pipe being filled with a fluid and the end of said pipe protruding out of the top of the housing (8) being provided with a condenser head (11) for condensation of the fluid evaporated in the metal pipe (9). The evaporator (2) has a container (13) holding the water (15) to be evaporated into which the condenser head (11) of the solar collector (1) protrudes in order to evaporate the water (15) by heating said water to the boiling point.
