Description
Technical field
The utility model relates to the exhaust-gas treatment field, particularly a kind of desulfurization and dedusting technology for boiler.
Background technology
At present, flue gas desulfurization technique has hundreds of in the world, but has only tens kinds of the techniques of practical value.It can be divided into three kinds of wet method, dry method and semidry methods according to the existence of desulphurization reaction thing and desulfurization product, wet desulfurizing process is widely used.Wet fuel gas desulfurizing technology is to adopt liquid-absorbant washing SO2 flue gas to remove SO2.Common method is lime/lime stone absorption process, soda method, aluminium method, catalytic oxidation-reduction method etc., and Wet Flue Gas Desulfurization Technology is low with its desulfuration efficiency height, wide accommodation, calcium sulfur ratio, technology maturation, the accessory substance gypsum can be done the advantages such as commodity selling becomes the fume desulphurization method that dominates in the world.But the shortcomings such as investment is large, power consumption is large, floor space is large, equipment is complicated because Wet Flue Gas Desulfurization Technology has, operating cost and specification requirement height are so limited its development speed.And at present both at home and abroad after the Wet Flue Gas Desulfurization Technique of usefulness all is that doctor solution is atomized in various manners and be cleaned the flue gas contact mass transfer, namely be to make droplet surface alkalinty material generate salt with sulfur dioxide reaction and sulfur dioxide is removed, this mode gas phase is continuous phase and liquid phase is decentralized photo, atomizing is better, the gas-liquid contact area is just larger, the larger droplet of sprinkle density is just more, removal rate of sulfur dioxide is just higher, but the interfacial resistance that this way drawback is mass transfer is large, be consumed because of the basic species on droplet surface and sulfur dioxide reaction, the droplet surface is in case be generated the thing parcel, the surface namely loses activity, and gas-liquid interface is not because there being renewal impetus not to be updated, thereby removal rate of sulfur dioxide is difficult improves.
In sum, there is following deficiency in the present desulfurization and dedusting technology that is used for boiler: one, the interfacial resistance of mass transfer is large, affects treatment effect; Two, power consumption is high, floor space is large, equipment is complicated, operating cost and specification requirement are high; Three, unstable working condition, adaptability are strong not.
