Venturi scrubbing tower

Abstract

The utility model relates to exhaust treatment technical field, concretely relates to a venturi scrubber, including spray tower, venturi, the spray tower is connected with venturi through arc transition pipe, is equipped with the air inlet on venturi upper end, is equipped with the exhaust port in spray tower top, the arc transition pipe is accessed spray tower in tangent direction, is equipped with heating pipe in spray tower bottom, is equipped with wall flow pipe mechanism, baffle demister, backflushing pipe mechanism in spray tower upper end in proper order, is equipped with blowdown pipe in spray tower bottom, still include reagent circulation system, the reagent consumption of the application can reduce through reagent circulation system, reduce operating cost, avoid the influence of pollutant concentration being too high to wash effect through the constant renewal of circulating liquid simultaneously, adopt the multistage treatment process of "venturi pre-coagulation, tangent air inlet centrifugal separation, countercurrent spray washing, baffle demisting", combine reagent circulation and heating temperature control, realize the efficient purification to industrial waste gas.
