Wuchang environmental protection integrated desulfurization and denitration complete equipment is mainly divided into six parts: absorbent preparation system, flue gas transmission system, SO2 absorption system, process water system, intelligent electrical control system, and by-product recovery system. The outlet concentration of purified flue gas of Wuchang environmental protection flue gas desulfurization and denitrification integrated equipment is less than 50mg/Nm3, which meets the requirements of the "Emission Standard of Air Pollutants for Thermal Power Plants (GB13223-2011)". The purified flue gas processed by the complete set of technology meets the current national and local pollutant emission standards, and has significant environmental and social benefits.

At present, the flue gas desulfurization and denitrification dust collector technology of power station boilers in my country is mainly imported from Japan and some countries in Western Europe. Although the domestically built demonstration projects for the introduction of flue gas desulfurization and denitrification equipment have advanced equipment, stable operation, and high degree of self-control, their investment and operating costs are extremely high, and the current situation in my country cannot be fully promoted and applied. Therefore, the main task of our company is to develop the flue gas desulfurization and denitrification technology according to my country's national conditions, with relatively low investment and operating costs, and to meet the needs of my country's market, and to achieve industrial applications.  

Working principle of Wuchang desulfurization and denitration equipment:

Harmful flue gas enters the desulfurization and denitrification integrated machine first through the cyclone mechanism and the alkaline water to explode and split into the alkaline water molecule group, continue to cyclone, and then through the micro-decomposition diving mechanism gas-liquid two-phase combination to fully contact, the sulfur dioxide, nitrogen in the flue gas Oxides, heavy metals and dust are fully absorbed by the water at the same time. The purified flue gas is heated by the heating and heat dissipation device in the desulfurization and denitrification equipment, and then is dehydrated by the cyclonic dehydration and demisting device to reach the standard, and then enters the chimney through the induced draft fan and is discharged into the atmosphere.

  Flue gas desulfurization and denitrification technology is a boiler flue gas purification technology used in the chemical industry that generates multiple nitrogen oxides and sulfur oxides. Nitrogen oxides and sulfur oxides are one of the main sources of air pollution. Therefore, the application of this technology is very helpful for environmental air purification. Currently known flue gas desulfurization and denitrification technologies include pyrolusite method, electron beam ammonia method, pulse corona method, gypsum wet method, catalytic oxidation method, microbial degradation method and other technologies.

Simultaneous flue gas desulfurization and denitrification technology is currently mostly in the research and industrial demonstration stage, but because it can achieve both desulfurization and denitrification in a set of systems, especially with the continuous tightening of NOX control standards, the desulfurization and denitrification technology is being affected by various countries. The increasing attention. There are three main types of simultaneous flue gas desulfurization and denitrification technologies. The first type is a combination of flue gas desulfurization and flue gas denitrification; the second type is the use of adsorbents to simultaneously remove high-hazard air pollutants such as NOX and SOX; the third type is a combination of flue gas desulfurization and flue gas denitration technologies; The flue gas desulfurization system was modified to increase the denitration function.

Application areas:

Integrated desulfurization and denitrification equipment is generally used in the environmental protection field of flue gas desulfurization and denitrification in thermal power generation, steel, cement, petrochemical, glass, coal-fired, gas-fired boiler heating and other enterprises.
