Description

A kind of flue-gas dust-removing and desulfurization system that can Based Intelligent Control exhaust rate
Technical field
The present invention relates to a kind of useless flue-gas dust-removing and desulfurization treating apparatus.
Background technology
China is that a few take one of country that coal is main energy sources in the world, coal accounts for the ratio of China's primary energy production and consumption always more than 70%, burnt gas has formed huge environmental pollution as the discharge of sulfur dioxide, nitrogen oxide, fundamentally administers the pollution that the discharge of sulfur dioxide and nitrogen oxide causes imperative.
Owing to can inevitably produce a large amount of flue gases and flying dust in industrial production, in flue gas, also contain a large amount of fine particles dust, these dust directly discharge meeting cause severe contamination to environment, to ecological environment, cause destruction in various degree, bring harm to people's Health and Living.Countries in the world environmental protection organization constantly strengthens the improvement of protection, especially atmosphere pollution to environment, industrial gas emission is enforced to control techniques, so some gas cleaning cleaners arise at the historic moment; In quite a while in the past, electric cleaner has been played the part of very important role therein; Yet along with improving constantly that people require living environment, environmental protection organization is also corresponding has both at home and abroad put into effect new discharge standard, and the control of pollution sources has been had to higher requirement.
During burning, the sulfur dioxide of a large amount of discharges, causes China to occur large-area acid rain, and development.In the eighties, the acid rain of China mainly occurs in take the southwest that Chongqing, Kweiyang and Liuzhou is representative, and Acid Rain Zone area is about 1,700,000 square kilometres.To the mid-90, acid rain has developed on the south the Changjiang river, the wide geographic area in to the east of Qinghai-Tibet Platean and the Sichuan Basin, Acid Rain Zone enlarged areas more than 100 ten thousand square kilometres.Take the Acid Rain Zone, Central China that Changsha, Ganzhou, Nanchang, Huaihua is representative has become the most serious area of national Acid Rain Pollution now, and the average annual Precipitation pH in its center is lower than 4.0, acid rain frequency is up to more than 90%, has arrived the degree of " meet rain must acid "; Take the Coastal East China that Nanjing, Shanghai, Hangzhou, Foochow and Xiamen be representative also becomes the main Acid Rain Area of China; It should be noted that the Beijing-Tianjin in North China, acid precipitation also appears in the areas such as the Dandong in northeast, Tumen again and again, average annual precipitation pH value has accounted for 30% left and right of national area lower than 5.6 region area.Visible, the development speed of China's acid rain is very surprising, is still the trend increasing the weight of year by year at present.Research shows, in China's acid precipitation, sulfate radical is approximately 10: 1 with the ratio of the equivalent of nitrate anion, and therefore, the acid rain of China is sulfuric acid type, mainly by anthropogenic discharge's sulfur dioxide, is caused.China is because acid rain and sulfur dioxide pollution cause the economic loss of the aspects such as crops, forest and health to be about more than 1,100 hundred million yuan, approaches 2% of gross national product then, becomes the key factor of restriction China's economy and social development.Administer Chinese Acid Rain Pollution, will control sulfur dioxide (SO2) emissions total amount.
