What is the best way to desulfurize Industrial Electrostatic Precipitator?
     Boiler dust removal equipment using a certain concentration (here 28% as an example) of ammonia as a desulfurization agent, the formation of ammonia sulfate slurry, transported to the fertilizer plant processing system. Ammonia desulfurization used in the amount of ammonia required by the default PH control valve to automatically adjust and measured by the flow meter. The sulfuric acid amide crystals are crystallized from the saturated sulfuric acid ammonia slurry in a desulfurization precipitator to produce suspended particles of about 35% by weight. The slurry quilt is pumped to the treatment site, through the primary and secondary dehydration, and then sent to the fertilizer plant for further dehydration, drying, condensation and storage, through the boiler dust removal equipment flue gas desulfurization at the same time, industrial electrostatic precipitator also generated Considerable by-product, to achieve a certain economic benefits.
    Industrial electrostatic precipitator flue gas path: flue gas from the existing electrostatic precipitator and blower through the flue system; flow through a 100% axial flow booster fan, into the desulfurization tower. After the flue gas enters the desulfurization tower, it is in contact with the countercurrent spray including the aqueous ammonia slurry, where the SO2 is absorbed by the aqueous slurry. The slurry is then saturated with the gas and cooled from the inlet temperature of 135 ° C to 50 ° C, followed by the passage of the gas through the two corrugated demister at the top of the desulfurization tower, the two efficient demister mounted on the upper part of the desulfurization tower, In order to remove droplets from the (flue gas). The gas in the running spray tower leaves the desulfurization tower and passes through the boiler again to reheat the gas and enters the existing chimney device at a temperature of 80 ° C according to the designed operating conditions. Industrial electrostatic precipitator Ammonia desulfurization, is the control of sulfur dioxide emissions technology, dust collector can not only remove sulfur dioxide in the flue gas, and can produce high value-added ammonia fertilizer products.
    Industrial Electrostatic Precipitator Desulfurization Tower Liquid Path: The pH of the slurry in the desulfurization tower is maintained at 5.05.9, which optimizes the removal efficiency of SO2 and the oxidation rate of ammonia sulfide. Ammonium sulfate is easy to dissolve, up to 40% by weight under conventional conditions, and up to 48.5% under desulfurization tower operating conditions. The desulfurization tower is operated in a controlled condition containing 3-5% by weight of suspended crystal particles. The desulfurization tower feed pump delivers the slurry to the first stage dewatering cyclone. The overflow slurry of the cyclone is returned to the desulfurization tower, and the lower part of the cyclone, containing a concentrate concentration of 1317% by weight, is fed to the cyclone tank. A slurry pump sends the concentrated slurry in the tank to the second stage dewatering cyclone in the fertilizer plant for further dewatering. A filtrate back to the pump will be the fertilizer plant was centrifugal dehydrator out of the dilute liquid back to the desulfurization tower. Reactor supply system for Industrial Electrostatic Precipitator: Ammonia reactant supply system includes storage tanks for 7 days and storage pumps. 28% of the concentration of ammonia through the bottom of the desulfurization tower oxidation distributor and oxidized air and cooling water mixed together into the desulfurization tower. A control valve with a preset pH controls the flow of ammonia.
