The invention discloses a process and device for wet desulfurization,
denitrification and dust removal, which is characterized in that a
slurry pool, an inlet
flue, a rough
dust collector, a first-stage desulfurization spray layer, and a first-stage gas-raising are arranged in the shell of the absorption
tower from bottom to top. Liquid collector,
denitrification spray layer, two-stage gas-lift liquid collector, two-stage desulfurization spray layer, three-stage gas-lift liquid collector, high-efficiency
dust collector, high-efficiency
dust collector flushing layer, mist eliminator and mist eliminator flushing layer, outside the shell of the absorption
tower, there are
slurry pumps, overflow pipes,
denitrification liquid collection tanks, denitrification pumps, denitrification
slurry return pipes, desulfurization liquid collection tanks, desulfurization pumps, desulfurization slurry return pipes, dust collection liquid collection boxes, flushing pumps, dust removal slurry The return
pipe, the present invention has good effect of simultaneous desulfurization, denitrification and dust removal, good gas-liquid
mass transfer effect, large gas circulation space without blockage, less investment,
small footprint, stable and reliable operation, simple structure and low cost, convenient installation and maintenance, etc.
advantage.
