Method and device for accelerating salt obtaining by evaporating brine

The invention provides a device for accelerating salt obtaining by evaporating brine. The device comprises a light-heat conversion part, a buoyancy ball and a locking part, wherein the light-heat conversion part wraps the buoyancy ball, and the locking part fastens the light-heat conversion part. The invention further provides a method for accelerating salt obtaining by evaporating brine. The method comprises the following steps that an aqueous solution to be treated is added, accessories are selected and assembled, the light-heat conversion part wraps the buoyancy ball and is fastened by using the locking part, the device is placed in a water pool, the buoyancy ball floats in the water pool, the remaining part of the light-heat conversion part stretches into the water pool to carry out light absorption and light-heat conversion so as to quickly evaporate water absorbed by the light-heat conversion part, the light-heat conversion part carries out capillary action to quickly supply water.
