Description

A kind of novel efficient system for desulfuration and denitration

Technical field

The utility model belongs to distribution box field, and in particular to a kind of novel efficient system for desulfuration and denitration.

Background technology

At present, China's energy is based on fire coal, and metal smelt process, can produce a large amount of sulfur dioxide, at present, I The annual SO2 emissions of state have been up to 40,000,000 tons, and this is to cause haze one of the main reasons today, and in these flue gases Sulfur dioxide concentration it is high more than 10%, and low less than 1%, it is very big that this results in recovery difficult.For many years, China's input With in the desulfurization project built, major part is all that to use with calcium base wet-process flue gas desulfurization be main Treatment process.Calcium base wet-process flue gas Generally using calcium carbonate and calcium oxide as desulfurizing agent, desulfurization product is gypsum for desulfurization, and the gypsum resource of China is abundant, after desulfurization Its impurity of gypsum is too many, and canopy pine is unreal, does not have use value, but cannot process, as pollution source, in fact, This is the technology that another pollution is substituted with a kind of pollution modes, even so, because the cost of the sulfur removal technology technology is too high, Desulfurization product can not bring benefits again, it has also become the great burden that can't stand is held by enterprise,【One large desulfurization denitration device, year Operating cost is up to tens million of units, and a small-sized heating station, the operating cost in a winter also needs millions of units】This just forces the producer to be Cost-effective, using desulphurization plant mostly as dealing with inspection, the ostentatious project all not put into operation really actually makes cigarette Sulfur dioxide in gas, is not all just stolen by the directly row of stealing through treatment and is put into air mostly, and this is already well-known in industry The fact；This is also China's main basic reason that today, haze was administered more serious and more serious！But, on the one hand, sulphur is again China's work The essential important source material of agricultural production, and China due to sulphur mineral resources very little, China's gas washing in SA production is always to rely on big Imported sulphur is measured to process, if, a kind of low cost of invention, the novel desulphurization technique of process is simple is set, by industry Sulfur dioxide in flue gas is used for being produced into sulfuric acid, to substitute the sulfuric acid of sulfur cream！This just can directly by this main air The malicious source of pollution, transforms into huge resource, therefore, the sulfur dioxide low cost conversion in industrial smoke is produced into sulfuric acid work Skill, is the green technology of most preferable doulbe-sides' victory.Consequently, it is possible to this will make desulfurization emission reduction, voluntarily give as manufacturing enterprise The profit project for changing harmful to treasure for receiving, occurs so as to will thoroughly prevent the row of stealing and steal Fang Shi parts！Effected a radical cure in haze While, can also be that country saves the huge foreign exchange for buying sulphur.

Sulfur dioxide in industrial smoke is processed into sulfuric acid, this at home and abroad early has sub-fraction producer and has this Aspect transformation technology facility, but all because its technique excessively complicated, operating cost is too high, the cost for especially producing ozone is too high, Therefore, so far also only only tens of thousands of, ten tens of thousands of low discharges set and applied, it is difficult in the large-scale generating of millions of air quantity Application is realized in factory, therefore, haze to be made obtains real improvement, need a kind of new skills of new and effective cheap sulfur removal technology of Chong Art method.
