Abstract
The invention discloses a fume cleaning and desulfurizing system and a working method thereof. The fume cleaning and desulfurizing system comprises a fume inlet system, a desulfurizing reaction column, a cloth bag filtration dust removal reaction system, a heat exchanger, a fume heater, an SCR (selective catalytic reduction) denitration reaction system and a booster fan which are connected sequentially, wherein the booster fan is connected with the heat exchanger; and the heat exchanger is also connected with an original smokestack. Sintering fume enters the desulfurizing reaction column via the fume inlet system to be desulfurized, is subjected to dust removal through the cloth bag filtration dust removal reaction system, enters the fume heater through the heat exchanger, enters the SCR denitration reaction system, is pressurized by the booster fan, and discharged to the original smokestack through the heat exchanger. The invention is suitable for removing hydrogen sulfide and impurities in various combustion gases and coal gases, thereby enhancing the air quality and reducing the environmental pollution.
Description
Technical field
The present invention relates to a kind of gas cleaning desulphurization system and method for work thereof.
Background technology
Since early 1980s, along with China's economy continues to develop rapidly, the coal Year's consumption is with 5～12% speed cumulative year after year, and the annual emissions of SO2 is increasing year by year also.To 20 end of the centurys, the annual emissions of China SO2 is up to more than 2,000 ten thousand t, and China becomes the in the world the most serious country of air environmental pollution, also becomes in the world the third-largest Acid Rain Zone under the contamination of SO2.In 113 national prevention and control of air pollution key cities in 2002, have 40 average daily concentration of city SO2 to surpass national grade ii standard, account for 35.4%, 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 SO2 belongs to without the control discharging, China's Acid Rain Pollution also is difficult to control, and China's Acid Rain Pollution area accounts for more than 1/3rd of territory total area basically.China's atmosphere pollution is so serious, becomes in the world today to the greatest extent without only country.Future, economic rapidly sustainable development, the discharge capacity of SO2 also can increase year by year, and air environmental pollution control allows of no optimist.
Summary of the invention
Main purpose of the present invention is to provide a kind of can improve the flue gas quality, the gas cleaning desulphurization system of environmental contamination reduction.
