Product introduction of desulfurization and denitrification equipment for coke oven in coking plant:

Coking plant is an upstream enterprise of steel plant, mainly used as a specialized metallurgical enterprise to produce, process, recycle and smelt coking products. The main exhaust gases from the coke oven flue during the production process of coking plants are SO2, NOx, etc. These two compounds are the main components that pollute the atmosphere and are also the main detection objects for detecting whether the atmosphere is polluted. Therefore, the treatment of exhaust gas in coking plants requires both desulfurization and denitrification, as well as dust removal work.

The technical treatment of coke oven desulfurization and denitrification equipment in coking plants mainly includes dry desulfurization, semi dry desulfurization, SCR denitrification, SNCR denitrification, polymer denitrification and other treatment methods. Below, we will introduce the principles and characteristics of semi dry desulfurization and SCR denitrification technology:

1Working principle of semi dry desulfurization

In the treatment of coke oven flue gas in coking plants, we use semi dry technology. The flue gas first comes into contact with atomized sodium carbonate liquid in the SDA tower, which can purify the sulfur dioxide in the flue. At this stage, it is necessary to handle the indicators of various liquids to meet the standards. For example, sodium carbonate slurry needs to be atomized in the atomizer to ensure that the treated slurry can become a standard specification of 50 microns. After atomization, this slurry can be fully integrated into the flue gas and desulfurization tower, absorbing sulfur dioxide while effectively controlling the temperature and completing the desulfurization and purification work.

2、 SCR denitrification technology

In response to the ultra-low emission requirements of small and medium-sized boilers and kilns in coking plants, our company has developed a small SCR denitrification module equipment, including a urea solution (ammonia water) pump station metering and distribution integrated module, a complete set of ammonia production equipment (urea pyrolysis furnace, ammonia water evaporator), a small SCR reactor module, SCR control module, etc., which has the advantages of small footprint, high integration, fast construction, and high efficiency. The SNCR/SCR denitrification module equipment is widely used in industrial boilers such as chain furnaces, circulating fluidized bed boilers, coal powder boilers, gas boilers, biomass boilers, thermal oil boilers, three waste furnaces, molten salt furnaces, as well as industrial kilns such as glass kilns, ceramic kilns, cement kilns, calcination rotary kilns, tunnel kilns, brick and tile kilns, lime kilns, etc. Please follow our company website for more information http://www.btshhb.com
