Patent CN2018101895214 discloses a kind of blowing and boiling cold concentration pool. The hollow porous plate at the bottom of the concentration pool generates a large number of air bubbles through a blower. The rapidly rising air bubbles make the material boil, and the air bubbles take away the liquid material when passing through the liquid material quickly. moisture in. In this concentration device, the pores on the perforated plate at the bottom of the concentration tank belong to the same chamber. During the boiling process, the pressure at the edge of the perforated plate attenuates quickly, and the generated bubbles are mostly concentrated in the fan-shaped area opposite to the air supply pipeline. The dispersion of the bubbles is poor, and the bubbles tend to aggregate into large bubbles during the rise, and the effect of blowing and boiling is poor, and the evaporation efficiency is low.
