Description

Waste water concentration system based on supergravity device Technical Field The application belongs to the technical field of water treatment control, and particularly relates to a wastewater concentration system based on a supergravity device. Background The flue gas concentration tower adopts the technical principle that low-temperature flue gas before desulfurization is extracted to carry out evaporation concentration on wastewater. The wastewater is pumped to a concentration tower and continuously sent to the tower top for spray atomization through a circulating pump of the concentration tower. And part of desulfurization raw smoke is led out from a flue between the induced draft fan and the desulfurization tower, boosted by the booster fan and then enters the concentration tower. The flue gas contacts with the atomized circulating slurry in the concentration tower, water in the slurry is evaporated, liquid drops are removed from the flue gas and the evaporated water through a demister, and the flue gas enters a desulfurization system through a front flue of the desulfurization absorption tower. The circulating slurry is continuously concentrated, the wastewater volume is greatly reduced and thickened, and the slurry is conveyed to a tempering box after the solid content of the slurry reaches a certain concentration, and is conveyed to a terminal drying system after tempering treatment. The evaporation of the wastewater consumes a great deal of heat, and the larger the evaporation amount of the concentration tower is, the larger the amount of hot smoke extracted is, the larger the equipment scale of the concentration tower is and the power of the booster fan is, so that the higher the equipment investment and the running cost are. The two heat sources, namely hot water and hot flue gas, carry the same heat, and the power of a pump for conveying the hot water is much smaller than the power of a fan for conveying the hot flue gas due to the difference of density and specific heat. The waste water concentration system based on the supergravity device utilizes the air moisture-carrying principle, adopts heat medium water or steam as a heat source, and strengthens the gas-liquid mass transfer and heat transfer effect through the supergravity device so as to realize the purpose of waste water concentration and decrement.
