Description
Technical field
The utility model relates to a kind of system of moving-bed active coke combined desulfurization and denitration demercuration, belongs to the flue gases purification field.
Background technology
On July 29th, 2011, Chinese Ministry of Environmental Protection and State Administration of Quality Supervision, Inspection and Quarantine unite and have issued new discharging standards GB13223-2011 " fossil-fuel power plant atmospheric pollutant emission standard ", emission limit requirement to flue dust, SO2 in standard is stricter, and has increased the emission limit of NOx and Hg newly.If at coal fired power plant the desulfurization denitration demercuration device is installed respectively, not only floor space is large, and operation and maintenance is also wasted time and energy.In addition, some Industrial Boilers of China, such as the steel works sintering machine etc., its distribute wide, capacity is little, disposal of pollutants is high, is only second to station boiler.Although if adopt the Single Pollution thing to remove the disposal of pollutants problem that technology can solve coal-burned industrial boiler, cost and energy consumption are high, can not satisfy the requirement of energy-saving and emission-reduction and sustainable development.Therefore research and develop flue gas pollutant unite remove, flue gases purification that tail gas can recycling is significant.
Unite in the technology of removing at the pollution that caused by coal burning thing, the moving-bed active coke technology is little because of its floor space, can recycling, the characteristics of water saving, adapt to especially the coal fired power plant of China water-deficient area and the increasingly strict emission limit of steel works sintering machine of China.
The earliest activated coke dry method moving bed associating removing process by the Bergbau Forschung (being called for short BF) of Germany in exploitation in 1967, Mitsui mine Mitsui Mining(MMC) this technology is introduced Japanese in nineteen eighty-two with the BF cooperation.1992, AM General company's environment section (1997 by Ma Sulai green technology company (MET) purchase) and Mitsui mine signature technical protocol formed the MET-Mitsui-BF technology.At present, the Mitsui-BF technology has been used for the coal-burning boiler in Duo Jia power station.
