Title:
DEVICE FOR EXTRACTING MINERALS FROM BRINE BY USING SOLAR ENERGY
Document Type and Number:
WIPO Patent Application WO/2019/100957
Kind Code:
A1
Abstract:
Provided is a device for extracting mineral from a brine by using solar energy, comprising a solar collector (1), a heat exchanger (3) and an evaporation crystallization unit. An organic heat carrier in the solar collector (1) is a mineral oil type organic heat carrier and/or a synthetic organic heat carrier, and the organic heat carrier is heated to a temperature greater than 120 °C. The evaporation crystallization unit comprises an evaporation crystallizer (5), a condenser (6), and a condensate tank (7). The heat exchanger (3) is provided with a heat carrier inlet (21), a heat carrier outlet (22), a brine feed port (24) and a brine discharge port (23). The heat carrier inlet (21) is connected to the solar collector (1) through a heat exchanger pump (9), and the heat carrier outlet (22) is connected to the solar collector (1) through a circulation pipeline. The brine feed port (24) is connected to the raw material tank through a circulation pump (10), and the brine discharge port (23) is connected to the evaporation crystallizer (5). A vapor outlet of the evaporating crystallizer (5) is connected to a condenser (6), and a rear end of the condenser (6) is provided with the condensate tank (7). The condensate tank is connected to the vacuum pump (13). The bottom of the evaporating crystallizer (5) forms a circulation line through a pipe and a crystal slurry pump (11), and a crystal slurry discharge port is provided between the crystal slurry pump (11) and the circulation pipeline.
