Abstract
The utility model discloses a flue gas purification and desulfurization system which comprises a flue gas inlet system, a desulfurization reaction tower, a cloth bag filtering and de-dusting reaction system, a heat exchanger, a flue gas heater, an SCR (selective catalytic reduction) denitration reaction system and a booster fan which are connected in sequence, wherein the booster fan is connected with the heat exchanger; and the heat exchanger is also connected with an original chimney. The flue gas purification and desulfurization system is suitable for removing hydrogen sulfide and impurities in various fuel gases and coal gases, improving the air quality and reducing the environmental pollution.
Description
Technical field
The utility model relates to a kind of gas cleaning desulphurization system.
Background technology
Since early 1980s, along with China's economy continues to develop rapidly, coal year, consumption was with 5～12% speed cumulative year after year, SO
2Annual emissions also increase year by year.To 20 end of the centurys, China SO
2Annual emissions up to more than 2,000 ten thousand t, China becomes the most serious country of air environmental pollution in the world, at SO
2Contamination under also become the third-largest acid rain district in the world.In 113 national prevention and control of air pollution key cities in 2002,40 city SO are arranged
2Year, average daily concentration surpassed national grade ii standard, accounted for 35.4%, and the city that particle exceeds standard accounts for 72.6%.30 urban air-qualities are up to standard, and 44 urban air-qualities are three grades, and 39 urban air-qualities are inferior to three grades.Because coal fire discharged SO
2Belonging to does not have the control discharging, and China's acid rain pollutes and also is difficult to control, and China's acid rain contaminated area accounts for more than 1/3rd of territory total area basically.China's atmosphere pollution is so serious, and becoming does not have only country to the greatest extent in the world today.Future, economic sustainable development rapidly, SO
2Discharge capacity also can increase year by year, air environmental pollution control allows of no optimist.
The utility model content
Main purpose of the present utility model is to provide a kind of can improve the flue gas quality, reduces the gas cleaning desulphurization system of environmental pollution.
