Abstract

The invention discloses a garbage incinerator smoke gas treatment system, and belongs to the technical field of smoke gas desulfurization environment protection. The garbage incinerator smoke gas treatment system comprises a temperature reducing tower, an absorption tower, a cloth bag dust remover and a chimney in sequential connection, wherein a water atomization spray head is arranged at the top of the temperature reducing tower; a smoke gas inlet is formed in the top of the temperature reducing tower; a smoke gas outlet is formed in the lower part of the temperature reducing tower; a secondary spraying device is arranged on the top of the absorption tower; a ripple water film absorbing device is arranged under the secondary spraying device; an active carbon spraying pipe and a powdery slaked lime spraying pipe are arranged on a flue for connecting the temperature reducing tower and the absorption tower; the absorption tower is connected with a quicklime slurry feeding pipe; the quicklime slurry feeding pipe is connected with a quicklime slurry proportioning system. After the garbage incineration smoke gas passes through the system, the smoke dust is reduced to about 30mg / m<3>; the HCl is reduced to about 40mg / m<3>; the SOX is reduced to about 150mg / m<3>.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization environmental protection, in particular to a waste incinerator flue gas treatment system. Background technique [0002] Waste incineration technology is being increasingly widely used due to its advantages of high volume reduction rate and recyclable heat energy. Like the combustion process of coal, wood and other fuels, waste incineration will also produce flue gas. Due to the complexity of waste components, the flue gas generated by its incineration contains many harmful substances. The pollutants contained in waste incineration flue gas mainly include HCl, SO X , NO X and other acid gases and smoke. NO among them X It is mainly NO. According to the existing research results, the volume ratio of NO content in general flue gas accounts for NO X About 95% of the total. Compared with other acidic gases, NO has the characteristics that it is not deeper than water and does not d...
