SOLAR DISTILLER Russian patent published in 1999 - IPC

FIELD: solar-energy engineering; solar plants converting solar energy to thermal energy for desalting mineralized water (sea water, salt water). SUBSTANCE: distiller has housing with light- transmitting surface, heat-insulated reservoir filled with mineralized water, device for pouring mineralized water and draining concentrated brine, filtering device for cleaning and decontamination of condensate and reservoir for receiving the condensate. Housing of heat-insulated reservoir filled with mineralized water is made from heat-conducting material having high solar energy absorption factor and low degree of blackness. Shield mounted on bottom of housing of heat-insulated reservoir is made from material having higher solar energy absorption factor and degree of blackness on side of light-transmitting surface. Filtering device for cleaning and contamination of condensate is mounted before condensate receiving reservoir. EFFECT: high and stable productivity during entire period of operation; high quality of condensate.
