Dry desulfurization and denitrification equipment manufacturers: principles and operation of desulfurization, denitrification and dust removal equipment
Author：
As we all know, desulfurization, denitrification, and dust removal equipment is an ideal environmental protection device that has made outstanding contributions to the environment. So, do you know how it works to protect the environment? Dry desulfurization and denitrification equipment manufacturer Let me introduce it to you in detail!
The flue gas after desulfurization and denitrification enters the dewatering tank, where it rises spirally, completing the dewatering process. The dewatered flue gas returns to the flue gas heating device. The high-temperature flue gas undergoes heat exchange, raising the flue gas temperature above the dew point, solving the problem of moisture in the flue gas. After being reheated in the greenhouse, the flue gas is introduced into the chimney by the induced draft fan for emission in compliance with standards.
Desulfurization, denitrification and dust removal operation process:
Below, the dry desulfurization and denitrification equipment manufacturer shares the detailed process of desulfurization, denitrification, and dust removal equipment operation. When operating desulfurization, denitrification, and dust removal equipment, you can compare it. Flue gas operation path of boiler dust collector: Flue gas passes through the existing electrostatic precipitator and blower through the flue system; flows through the axial flow booster fan and enters the desulfurization tower. After entering the desulfurization tower, the flue gas contacts the countercurrent spray liquid containing ammonia water slurry, and the SO2 is absorbed by the ammonia water slurry. The slurry simultaneously saturates the gas and cools it from the inlet temperature of 135℃ to 50℃, and then the gas passes through two corrugated demisters at the top of the desulfurization tower. The double-layer demister is installed in the upper part of the desulfurization tower to remove the liquid droplets attached to the flue gas. The gas in the operating spray tower leaves the desulfurization tower, and is reheated by the boiler again, and enters the existing chimney device at a temperature of 80°C under the design operating conditions. Boiler desulfurization and dust removal tower liquid path: The pH value of the slurry in the desulfurization tower is maintained in the range of 5.0-5.9, optimizing the SO2 removal efficiency and the oxidation rate of ammonium sulfite. Ammonium sulfate is easily soluble. Under normal conditions, the solubility can reach 40% (by weight), while under the operating conditions of the desulfurization tower, this proportion can reach 48.5%. The desulfurization tower operates under controlled conditions with 3-5% by weight of suspended crystalline particles. The desulfurization tower conveying pump sends the pulp to the primary dewatering hydrocyclone. The hydrocyclone overflow slurry is returned to the desulfurization tower, and the concentrated slurry with a concentration of 13-17% by weight at the bottom of the hydrocyclone is sent to the hydrocyclone storage tank. The sludge pump sends the concentrated slurry from the storage tank to the fertilizer plant primary dewatering hydrocyclone for further dewatering. The filtrate return pump sends the thin liquid from the fertilizer plant centrifuge dewatering machine back to the desulfurization tower.
The dry desulfurization and denitrification equipment manufacturer said that the boiler desulfurization and dust removal reactor feed system: The ammonia water reactant feed system includes a storage tank with a storage capacity of 7 days and a conveying pump. 28% concentration ammonia water is sent into the desulfurization tower for oxidation through the distributor at the bottom of the desulfurization tower, and mixed with oxidation air and cooling water. The preset pH control valve controls the ammonia flow.
Application conditions: Ammonia desulfurization boiler dust removal not only removes harm but also turns harm into benefit, and can also produce beneficial by-products for humans. Boiler dust removal equipment turns acid rain that destroys land and crops into fertilizer for farmers.
The company mainly produces various dust removal, desulfurization, denitrification, VOCs waste gas purification, wastewater treatment, noise reduction, complete sets of industrial electrical control systems and equipment, and researches and develops waste gas, wastewater, waste residue, and noise treatment equipment.
