AI Technical Summary

Technical Problem

In the prior art, although the pH pH in the slurry is too high, it can increase the SO2 capture rate, but it will increase the consumption of limestone, causing too much limestone residue in the slurry, affecting the quality of the gypsum.

Method used

A slurry preparation device for wet desulfurization of flue gas at the tail of cement kiln is designed, including ash storage tank, conveyor rack, pulping box, desulfurization enhancer storage tank and related metering pumps, pipelines and stirring devices. By setting a pH detection probe in the pulping box, the delivery flow of the desulfurization enhancer can be automatically adjusted, and the pH pH pH pH of the slurry is controlled to be between 5.0 and 5.8.

Benefits of technology

By automatically adjusting pH pH, the consumption of limestone is reduced, the production quality of gypsum is improved, and the wet desulfurization process can be operated under relatively stable conditions.

Abstract

The slurry preparation device comprises a kiln dust storage tank, a conveying frame and a slurry preparation box, the conveying frame is arranged below a discharging port of the kiln dust storage tank, the slurry preparation box is arranged below the conveying frame, and the kiln dust storage tank and the slurry preparation box are arranged at the two ends of the conveying frame respectively. The system further comprises a desulfurization enhancer storage tank; a second fixed cover plate is fixedly arranged at the upper part of the desulfurization enhancer storage tank; data signals can be fed back to the first metering pump and the second metering pump through the pH detection probe arranged in the pulping box, and the first metering pump and the second metering pump can automatically adjust the conveying flow of the wet desulphurization reinforcing agent storage tank according to the change of the pH value, so that the pH value of the slurry is controlled to be 5.0-5.8; the wet desulphurization enhancer slurry produced by the equipment can automatically adjust the pH value, so that the wet desulphurization process can be operated under a relatively stable condition, the consumption of limestone is reduced, and the production quality of gypsum is improved.
