The invention discloses an industrial boiler denitration
system; a denitration mechanism, a
flue gas absorption pipeline, a desulphurization absorbing
tower, an underground spray dedusting
flue and a
gas analyzer are arranged so as to remove pollutants like
sulfide,
nitrogen oxide and dusts from
waste gas discharged by industrial boilers; the processed
waste gas quality can be monitored in real time, and intelligent adjustment can be carried out according to
monitoring data of the
gas analyzer, thus providing best
waste gas processing effect; the industrial boiler denitration
system comprises the denitration mechanism, the
flue gas absorption pipeline, the desulphurization absorbing
tower, the underground spray dedusting flue and the
gas analyzer; the denitration mechanism comprises a
liquid storage tank, a water pump, a convey pipeline and a control module, wherein the liquid outlet of the convey pipeline is arranged on to-be-denitrated equipment; the
liquid storage tank, the water pump, and the convey pipeline are connected in sequence; the desulphurization absorbing
tower comprises a
nozzle, two dispersion impellers, a convey pump and a
liquid storage pool arranged in the tower from top to bottom, wherein the
nozzle, the convey pump and the liquid
storage pool are connected in sequence.
