The utility model relates to the technical field of desulfurization and
denitrification purification towers, and discloses a desulfurization and
denitrification purification
tower capable of increasing the total
exhaust gas emission amount, which comprises a
tower body, a dust treatment mechanism is arranged on the left side of the
tower body, a desulfurization and
denitrification treatment mechanism is arranged in the tower body, the top end of the tower body is fixedly connected with an emission
pipe, and the top end of the tower body is fixedly connected with an
exhaust pipe. Residue particles in
waste gas can be filtered by arranging the filter screen, the conveyed
waste gas can be in full contact with sprayed desulfurization and denitrification liquid by arranging the desulfurization and denitrification treatment mechanism, the
staying time of the
waste gas in the tower body can be prolonged by arranging the two staggered through holes, so that the waste gas can be in more thorough contact, and the desulfurization and denitrification treatment efficiency is improved. And by arranging the gas detection mechanism, the treated gas is detected through a
toxic gas sensor, when
toxic gas exists in the detected gas, the gas can be subjected to desulfurization and denitrification treatment again, when the detected gas is non-toxic, the gas can be discharged, use is convenient, the effect is good, and
air pollution is avoided.
