Abstract
The present invention relates to the technical field of flue gas demercuration, specifically a kind of coal-fired flue gas mercury removal adsorbent.Material described in the demercuration adsorbent is constituted by weight percentage：Flyash 40-60%, activated carbon 8-12%, calcium oxide 8-12%, cement 10-15%, clay 10-15%, sodium bromide 3-5%.It is an object of the invention to provide the high coal-fired flue gas mercury removal adsorbent of a kind of reduces cost, utilization rate.
Description
Technical field
The present invention relates to the technical field of flue gas demercuration, specifically a kind of coal-fired flue gas mercury removal adsorbent.
Background technology
The mercury of Discharged form Coal Combustion is the main source of mercury pollution in air.The research of superfine people, coal in China are played according to king
The average content of middle mercury is 0.22mg/kg and whole nation whole year Coal-fired capacity estimation, national power station Coal-fired capacity about 14 in 2010
Hundred million tons, mercury quantity is just discharged altogether up to 300 tons by power plant.Mercury in air can enter human body by respiratory tract or food chain,
It is detrimental to health.Mercury pollution problem has become whole world focus of attention, and the ring that China is in the urgent need to address
Border problem.As the form of Mercury In Coal Combustion Flue Gas is based on Elemental Mercury, research both domestic and external is concentrated mainly on demercuration absorption
The development of agent.The more adsorbents of research have five kinds mostly at present：Activated carbon, flyash are Ca-base adsorbent, expensive
Metal absorbent, metal oxide sorbents and mineral substance adsorbent etc..Various adsorbents all existing defects itself,
Although activated carbon is with higher demercuration efficiency, utilization rate is low.
The content of the invention
It is an object of the invention to provide the high coal-fired flue gas mercury removal adsorbent of a kind of reduces cost, utilization rate.
The technical solution used in the present invention is, a kind of coal-fired flue gas mercury removal adsorbent, material group by weight percentage
Into：Flyash 40-60%, activated carbon 8-12%, calcium oxide 8-12%, cement 10-15%, clay 10-15%, bromination
Sodium 3-5%.
It is an advantage of the invention that it is process is simple, with low cost, it is easy to promote the use of on a large scale, is freezed off using cement is added
Shaping, it is not necessary to sinter, technological process is short, cost is greatly reduced；And unsintered adsorbent specific surface area ratio
The height of slug type.
Specific embodiment
The present invention is further described with the following Examples.
Embodiment 1, a kind of coal-fired flue gas mercury removal adsorbent, the material are constituted by weight percentage：Flyash 60%,
Activated carbon 8%, calcium oxide 12%, cement 10%, clay 15%, sodium bromide 3%.
Embodiment 2, a kind of coal-fired flue gas mercury removal adsorbent, the material are constituted by weight percentage：Flyash 40%,
Activated carbon 12%, calcium oxide 8%, cement 15%, clay 10%, sodium bromide 5%.
Embodiment 3, a kind of coal-fired flue gas mercury removal adsorbent, the material are constituted by weight percentage：Flyash 50%,
Activated carbon 10%, calcium oxide 10%, cement 13%, clay 12%, sodium bromide 4%.
It should be understood that the embodiment is only illustrative of the invention and is not intended to limit the scope of the invention.Furthermore, it is to be understood that
After the content for having read instruction of the present invention, those skilled in the art can be made various changes or modifications to the present invention,
These equivalent form of values are equally fallen within the protection domain limited by the application appended claims.
