Device.
Background technique
The fast development of human society be unable to do without the supply consumption of the energy, in the energy consumption structure in China, coal-fired number
Amount about accounts for the 70% of non-renewable energy, and plurality of heavy metal is inevitably generated during the energy-consumings such as fire coal
(Hg0) etc. pollutants cause environment to break ring.Heavy metal Hg etc. has the characteristics such as strong toxicity, volatility and biological accumulation,
It is serious for breaking circumpolar to environment.In recent years, the heavy metal (Hg in coal-fired flue-gas is controlled0) etc. pollutants discharge increasingly by
Concern, China also put into effect relevant national standard in 2011, it is desirable that Mercury In Coal Combustion Flue Gas discharge amount is strictly less than 0.03mg/
m3, therefore the task of top priority is to find a reliable removing heavy metal (Hg0) etc. pollutants method.
Pollutant mainly includes the substances such as oxycarbide, nitrogen oxides, oxysulfide, mercury and other heavy metals in flue gas.
Heavy metal such as mercury highly volatile after fired coal combustion enters flue gas.For example, there are three types of existence form, nonvalent mercury, bivalent mercuries for mercury
And particulate Hg, wherein nonvalent mercury almost all after fired coal combustion is discharged into the atmosphere, and can be enriched in vivo, is caused
The serious broken ring of ecological environment.
There are mainly three types of modes for coal-fired flue-gas removing heavy metal: pre-processing before burning, controls after control, burning in burning.
The present domestic and international research for burning removing heavy metal is less, lacks systematic further investigation and technological achievement.At present
The main methods such as removing heavy metal Hg still utilize active carbon, and the adsorbents such as calcium chloride inhale heavy metal in flue gas mercury etc.
Attached removing, but removal efficiency is not high, and the research of new adsorbent also lacks breakthrough achievement.Another method is to pass through power plant
Fume treatment auxiliary heavy metal Hg etc. is removed, but power-plant flue gas processing equipment be difficult heavy metal Hg etc. is effectively de-
