High-salt wastewater photothermal evaporation device with self-cleaning function

Abstract

The utility model provides a kind of high-salinity wastewater photo-thermal evaporation device with self-cleaning function, and the evaporation device includes floating square frame and multiple cylindrical long evaporators placed in parallel in floating square frame;The surface of cylindrical long evaporator is provided with multiple groups of annular V-shaped grooves recessed in annular direction along axial direction interval;Cylindrical long evaporator adopts solid material with density less than water, and can float freely in floating square frame;Annular V-shaped groove recessed can effectively enhance water flow driving torque and evaporation area.The placement depth of flow guide baffle is greater than the height of floating square frame, so that water flows obliquely upward along the bottom of flow guide baffle, forming oblique water flow shear force to drive cylindrical long evaporator to rotate.The utility model has the advantages of simple structure, excellent salt resistance, large evaporation area, easy maintenance, etc., and is suitable for solar photo-thermal evaporation concentration treatment of high-salinity wastewater.
