The utility model is related to a kind of desulfurization wastewater zero-emission coupling damping Improvement of dust removal system, including the desulfurizing tower sequentially connected, gypsum dehydration system, waste-water vortex device, waste water tank, rotary spray evaporation tower and deduster, waste water after being handled through gypsum dehydration system is after the processing of waste-water vortex device, a part of underflow goes desulfurizing tower to reuse, a part of overflow goes waste water tank to collect, waste water is delivered to rotary sprayer and is atomized, droplet after atomization is descending, drive in the wrong direction and contact with the high-temperature flue gas accessed before air preheater, solid particle integrally comes downwards to rotary evaporation tower bottom with flue gas in waste water after evaporation, rotated evaporating column exhaust pass enters front flue of dust collector, waste water enters desulfurizing tower in the form of purifying vapor by deduster.The utility model waste water treatment stability is high, is not influenceed by unit load, and investment and operating cost are low, saves water consume and energy consumption, realizes wastewater zero discharge while increasing smoke moisture, improves deduster efficiency of dust collection. |
