Salt-containing wastewater concentration system

The utility model relates to the field of high-salt wastewater treatment equipment, in particular to a salt-containing wastewater concentration system which comprises at least one supergravity concentration device, a heat pump unit and a sedimentation tank, the supergravity concentration device comprises a shell, a liquid inlet pipe and a first air outlet are arranged at the top of the shell, an air inlet and a water outlet are respectively arranged at the bottom of the shell, the first air outlet and the air inlet are respectively communicated with an evaporation chamber of the heat pump unit, the liquid inlet pipe and the sedimentation tank are respectively communicated with a condensation chamber pipeline of the heat pump unit, and the water outlet is communicated with a sedimentation tank pipeline. Compared with the prior art, the mass transfer coefficient and the mass transfer flux are improved by combining the modes of mass transfer and centrifugal atomization of hot water and cold air, the evaporation
