| titleOfInvention | A kind of method and device of desulfurization method of limestone-gypsum ORP and pH double controls |
| abstract | The invention particularly relates to a kind of method and devices of desulfurization by lime gypsum method slurries ORP and pH double controls.PH is adjusted in the range of suitable for desulphurization system operation by lime stone slurry internal circulating load first, then under the conditions of current pH, pH, ORP, DO value and HSO of desulfurization slurry in the sample cell and comparison groove that measure 3 ﹣ And SO 4 2‑ Content data be sent to arithmetic center and analyzed, calculate the deviation of signal with desulfurization slurry under complete oxidation state in sample cell, the oxidization condition and oxygen demand of desulfurization slurry are determined by deviation of signal, and it transmits the signal to oxidation fan and oxidized input air is controlled, the oxidation that desulfurization slurry is accurately controlled from theoretical depth controls the nucleation and crystallization situation of gypsum, is conducive to the gypsum for producing high-quality, oxidation fan power consumption is reduced, desulphurization system operating cost is saved.The present invention is by real-time ORP and pH on-line monitorings adjustment, it can be achieved that desulphurization system optimizes. |
