Description
Technical field
The present invention relates to the technology that a kind of thermal power plant chimney smoke utilizes, specifically flue gas condensing separation system of mixed gas.
Background technology
Power plants is huge, and at continuous expansion scale, ever-increasing ultrafine dust and sour gas SO
2, NOx causes huge pollution and harm, CO to agricultural, forestry, building and ecological environment
2discharge be subject to the restriction of " Kyoto Protocol " and " Copenhagen agreement ", therefore solve dust, SO
2, CO
3, NOx emission problem, just solved the main energy sources problem of China, thermal power plant just no longer becomes unsustainable development industry.
China is coal-fired big country, is main energy sources source.According to statistics, coal fire discharged SO is only in China 2005
2be 2,549 ten thousand T, rank first in the world, flue dust 1,488 ten thousand T, CO
2be 3,900,000,000 T, NOx is 1,300 ten thousand T.
SO
2, NOx is very large to the harm of human body, especially works as SO
2be oxidized to after sulfuric acid mist, combine and enter human respiratory tract and lung with airborne fine particle thing, can cause the malignant diseases such as bronchitis, pneumonia, pulmonary edema.
SO
2, NOx still forms the arch-criminal of " acid rain ".According to the study, the economic loss that China's acid rain caused agricultural, forestry and construction material destruction is in recent years every year up to more than 200 hundred million yuan.
Nitrogen oxide can form " photochemical fog " in the sun, and this is a kind of pale blue smog with intense stimulus, and air quality is worsened, and health and the ecosystem are caused damage.
CO
2have " greenhouse effects ", its harm is well-known.
Flue dust mainly suspends and transmits with the form of particle in atmosphere, and it both can reduce atmospheric transparency, affected photosynthesis of plant, again health was caused to very big harm.
In addition, the size range of the particle in flue dust is at a few nm～100nm, and all in unformed state, has higher chemism, be a kind of good nano level concrete mineral matter admixture, collect and there is good Technological Economy and social benefit.All without coal-fired power plant chimney smoke being carried out to dedusting, reclaim SO both at home and abroad at present
2, CO
2, NOx enterprise.
For above-mentioned situation, develop a set of flue gas collection processing system implementing, design one covering device, absorbs flue dust (nanoscale concrete mineral matter admixture), filters and clean flue gas, obtains to take the mist that CO2, SO2 and NOx be main component.
Flue gas absorbing device is collected the flue gas getting off and is contained a large amount of steam, after water vapor condensation, can produce water, must water is separated with other, just can carry out next step operation.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of can be by the device of flue gas separation after the flue gas condensing of collecting from chimney of electric plant.
For solving the problems of the technologies described above, flue gas condensing separation system of mixed gas of the present invention, comprise the fume pipe that connects flue gas absorbing device, the lower end of fume pipe arranges elbow, periphery at chimney arranges a circle flue gas separation unit, and flue gas separation unit comprises water seal circle and gas transmission circle, and the cross section of described water seal circle is U-shaped, one end of gas transmission circle and water seal circle is tightly connected, and connects condensate return pipe and mixture pipe on gas transmission circle.
One side of the described gas transmission circle around chimney arranges low spot, and described condensate return pipe and mixture pipe are arranged on low spot.
Adopt after such structure, smoke absorption system is returned off-gas recovery, the steam condensation separation in system of the present utility model in flue gas, and isolated mist is through washing dust pelletizing system, and ultrafine dust enters sedimentation basin.Condensed water after precipitate and separate can be used for the mist that washing is separated, and the ultrafine dust in mist is separated.Ultrafine dust drying is a kind of nano level quality concrete admixture after processing, to fully be utilized, and be there is very high Technological Economy value, especially when preparing high-strength and super high strength concrete, ultrafine dust just becomes and is important, and become must be little key component.Mist after washing, pressurization is cooled to after certain pressure and temperature, SO
2by liquefy product, continue pressurization and be cooled to after certain pressure and temperature, CO
2also by liquefy product.CO
2and SO
2itself be exactly important industrial chemicals, the lime stone that can significantly reduce thus decomposition resource scarcity obtains CO
2obtain SO with a large amount of sulphur of burning or sulphur ore deposit
2; SO
2and CO
2also can be used to produce Na
2sO
3and Na
2cO
3.
The additional chemical products of this system gained have very large cost advantage, and market competition advantage is obvious, and Social benefit and economic benefit is huge.
