Description
Technical field
The present invention relates to thermal power plant field, relate to a kind of chimney desulfurated plaster rain piece-rate system particularly.
Background technology
At present, in the use procedure of thermal power plant, due to liquid particles in flue gas cannot by lifting effectively, be diffused in air, easily form " desulfurated plaster rain " or acid rain phenomenon at power plant and periphery, power plant and surrounding enviroment produced and pollutes.
In prior art, the method of control desulfurated plaster rain mainly contains following several: 1) adopt gas-to-gas heat exchanger (gasgasheater, GGH) device, to utilize before desulfurizing tower flue gas after flue gas desulfurizing tower, neat stress temperature after heating is higher, flue gas can obtain lifting effectively after chimney is discharged, thus prevents the generation of desulfurated plaster rain phenomenon.But GGH device in use exists a lot of shortcomings, as energy waste, easily blocking, investment is large, return rate is low, and wherein easily blockage problem will have a strong impact on the safe and stable operation of GGH system and power plant.2) adopt tubular type GGH device, identical with common GGH operation principle, difference is, by by original gas-gas direct heat transfer, to change the mode of air-water-gas into.The method investment is large, and the etching problem produced is difficult to solve.3) adopt " Wet chimney " scheme, namely cancel GGH device, adopt Limestone-gypsum Wet Flue Gas Desulfurization Process technique, directly neat stress is discharged from chimney, and chimney adopts the scheme of inside lining anti-corrosive material.This scheme is not owing to adopting GGH device, though the blockage problem of GGH effectively can be avoided, be beneficial to power plant safety stable operation, but because " Wet chimney " exhaust gas temperature is lower, absorption tower outlet is with the neat stress of saturation water, form drop at discharge process partial condensation, flue gas effectively can not be lifted, be diffused in air after throat is discharged, therefore effectively cannot solve desulfurated plaster rain phenomenon.4) adopt nature draught cooling tower, there is restriction in this technology in national environmental protection policy.5) desulphurization system is optimized, but the limited efficiency that this method receives, fundamentally can not solve desulfurated plaster rain phenomenon.6) reduce flue gas flow rate in chimney, this method initial investment, greatly, to old power plant without reference, does not have effective supporting gypsum rain drop collection method, effectively cannot solve desulfurated plaster rain phenomenon.
In sum, all there is a series of shortcomings such as technological investment is high, relative yield is low, popularization is difficult in the method for the existing solution in this area desulfurated plaster rain phenomenon, in order to effectively address this problem, this area comparatively can obtain comparatively high yield by low cost in the urgent need to developing one, and is suitable for the new method that effectively can solve the desulfurated plaster rain phenomenon that smoke stack emission is formed of new power plant design and old repowering simultaneously.
