Cyclone mixing device for desulfurizer

Tangshan Donghai iron and steel sintering plant project

The flue gas of sintering machine enters the sodium based (NaHCO3) dry desulfurization (sodium based dry) dust removal integrated system. The flue gas first enters the sodium based dry desulfurization reactor (Party A's existing pipeline), and the sodium bicarbonate ultra-fine powder is sprayed into the sodium based dry desulfurization reactor (Party A's existing pipeline). The sodium bicarbonate ultra-fine powder decomposes into highly active sodium carbonate and carbon dioxide under the action of high-temperature flue gas. The highly active Na2CO3 is fully contacted with SO2 and other acidic media in the flue gas to produce chemical reaction and be absorbed and purified. After desulfurization, the powdery particle products enter the bag filter with the air flow to collect the desulfurization by-products.

The emission concentration of waste gas particulate matter is less than 10mg / Nm3 (dry basis), which is guaranteed by the original dust removal system. The emission concentration of sulfur dioxide is less than 35 mg / Nm3 (dry basis), and the concentration of nitrogen oxides does not increase.
