Increase；Nitrogen oxides pollution is in exacerbation trend.Coal consumption amount is continuously increased, bring therewith sulfur dioxide (SO2) emissions total amount drastically on
Rise.In all kinds of emission sources, power plant and Industrial Boiler discharge capacity account for 70%.Cause to obtain Acid Rain Pollution model by sulfur dioxide (SO2) emissions
Enclose continuous expansion.The primary discharge source of flue dust is also thermal power plant and Industrial Boiler, and what is used due to local power factory is mostly poorly efficient
Deduster, so smoke discharge amount is usually 5-10 times of national large power plant.At present sulfur method typically have burning before, burning
Neutralize three kinds of desulfurization etc. after burning.With industrial expansion and the improvement of people's living standards, the craving to the energy also constantly increases
Add, the SO in coal-fired flue-gas2The main reason for having become atmosphere pollution.Reduce SO2Pollution has turned into current atmospheric environment and administered
The task of top priority.Many flue gas desulfurization technique extensive uses in the industry, it is controlled all kinds of boilers and tail gas from incinerator
Reason also has important practical significance.At present sulfur method can typically be divided into burning before desulfurization, burning in desulfurization and burning after
The class of desulfurization etc. 3.Desulfurization, also known as flue gas desulfurization (FGD) after wherein burning, in FGD technologies, divided by the species of desulfurizing agent, can
It is divided into following five kinds of methods：With CaCO3Calcium method based on (lime stone), the magnesium processes based on MgO, with Na2SO3Based on
Sodium method, with NH3Based on ammonia process, organic alkaline process based on organic base.The commercial technologies generally used in the world
It is calcium method, proportion is more than 90%.By absorbent be the dry and wet state of alkalies and desulfurization product in sweetening process again

Liquid or slurries desulfurization and processing desulfurization product under wet condition, the method have that desulphurization reaction speed is fast, equipment is simple, desulfuration efficiency
The advantages that high, but generally existing seriously corroded, operation and maintenance cost are high and easily cause secondary pollution problems.Dry method FGD technologies
Desulfurization absorption and product processing carried out under dry state, the method has without the discharge of sewage spent acid, equipment corrosion lesser extent,
Flue gas in purification process without cigarette temperature after significant hypothermal, purification it is high, beneficial to chimney exhaust diffusion, secondary pollution less the advantages that, but
It is low to there is desulfuration efficiency, reaction speed is compared with the problems such as slow, equipment is huge.Semidry method FGD technologies refer to desulfurizing agent in drying regime
Lower desulfurization, regeneration (such as the washing regenerating active carbon flow) under wet condition, or under wet condition desulfurization, handled under dry state
The flue gas desulfurization technique of desulfurization product (such as spray drying process).Particularly under wet condition desulfurization, handle desulfurization under dry state
The semidry method of product, the advantages of existing wet desulphurization reaction speed is fast, desulfuration efficiency is high with its, there is dry method to be arranged without sewage spent acid again
Go out, after desulfurization the easy-to-handle advantage of product and widely paid close attention to by people.By the purposes of desulfurization product, the method for abandoning can be divided into
With two kinds of absorption method.
