What does means of off-gas treatment of power industry industry have?

Industrial waste gas is the main source of air pollution content, discharge many industry waste gas to be able to reduce atmosphere environment quality necessarily to atmosphere, endanger human body health badly, damage national economy badly. Accordingly, extremely urgent of industrial off-gas treatment.

Industry produces the power plant that has a lot of kinds, for example the many power station such as power station of firepower power station, hydroelectric station, nuclear power plant, terrestrial heat, wind- driven power station, tide power station, solar energy power station. Because these power plant use different power source, waste gas is measured and the quantity of the contaminant in waste gas is different.

Among them, because hydraulic, nuclear energy, terrestrial heat, wind- driven, tide can use cleaner the sources of energy with solar energy power station, lesser to atmosphere environment influence. Firepower power station uses coal fired boiler, its discharge capacity is much, flue gas part is complex, air pollution is serious, flue gas of boiler of coal fired of firepower power station is the most important in power industry discharge contaminative source.

The waste gas of coal fired power plant basically originates the dust waste gas that the smoke that boiler combustion produces, coal ash transports the waste gas or steam that gathers in the system, coal yard to arise and the dust that coal produces. Among them, the smoke that boiler combustion produces is measured and among them the cigarette volume that the quantity of contaminant compares combustion of boiler of other waste gas to arise is much much. A few fly ash, SO2, NO2, CO, CO2, HB, fluoride and chloride. Their scale depends on the mineral composition of coal. Main contaminant is fly ash, grime, SONOx, Hg. Boiler combustion can arise to many flue gas is discharged and discharge air temperature high, but the chroma of gaseous contaminant normally very low.

Want to handle waste gas of coal fired power plant, advance clean coal technology energetically, undertake technical reformation as soon as possible, strengthen business management, reducing coal to use up is one of important methods of the power plant, reduce exhaust emission. In the meantime, we still should be developed actively and use effective off-gas treatment technology and integrated resource to use a technology. Use bag of efficient dust arrester, report for example compound dust arrester and smoke evacuation of boiler of purify of hop-pocket dust arrester, undertake effective to decoke, turn over nitrify, power plant to turn over nitrify, mercuric couplet to produce measure new technology and new facility.
