Description
Technical field
The utility model relates to a kind of wet plume condensations to take off white device, belong to flue gas desulfurization technique field.
Background technique
Desulfurization fume status: for the flue-gas temperature being discharged from desulfurizing tower generally between 50 DEG C~55 DEG C, flue gas is wet saturation
State, after flue gas discharge, white smog, referred to as wet plume is commonly called as " white cigarette ".If wet saturated flue gas, which is expelled directly out, to be brought
Two kinds of adverse consequences: first is that the lifting ability of flue gas is low, being unfavorable for flue gas dilution diffusion, may be formed about water mist in chimney,
Cause the local pollution of the environment, i.e. so-called flue gas " under wash "；Second is that cooling through air, wet saturated vapor is solidifying after flue gas discharge
Form acidic liquid sedimentation, i.e., it is so-called " rainy ", that is, environment is polluted, and cause to corrode to equipment and building.Therefore de-
In sulphur system, the wet saturated steam for reducing or removing in flue gas is particularly important.
Take off in the world to wet flue gas at present white mainly using following technique: flue gas reheats mode and directly heats and indirectly
Two kinds of heating.1000~1100 DEG C of high temperature cigarette heat that the mode of directly heating can be generated using natural gas or light diesel fuel burning,
It can directly be mixed using the untreated hot fume in part, no matter which kind of mode be used, it need to be based on thermal balance, not drop
Based on low emission requires.
Developed country usually uses flue gas reheat technique in processing desulfurization wet flue gas, i.e., will be taken off using the former flue gas of boiler
Sulphur flue gas is heated at least to 80 DEG C or more, is then discharged into atmosphere again.This flue gas reheat technique is can to eliminate white cigarette vision,
But the moisture percentage in flue gas is not can be reduced, therefore be a kind of palliative measure.
There is also heater surfaces easily to adhere to grit for flue gas reheat technique, causes the reduction of heater heat transfer efficiency, even
It causes heat transmitter to block, flue gas reheat is made to fail.Steam is blown into desulfurization wet flue gas to heat desulfurization fume there are also a kind of
Technique, this technique will largely waste heat source, it is clear that not meet national conditions, therefore more undesirable.
Many years effort is passed through in China in terms of environmental improvement, the smoke evacuation of current industrial coal combustion equipment by dedusting, desulfurization and
Denitration process greatly reduces pollution of the coal combustion equipment to atmosphere.But wet process is mostly used to the smoke evacuation of coal combustion equipment processing
Thus sulfur removal technology also brings the white cigarette problem that moisture percentage is high in the flue gas discharged after wet desulphurization.The white cigarette of discharge can band
Carry out following consequence: first is that the lifting ability of flue gas is low, being unfavorable for flue gas dilution diffusion, misty rain may be formed about in chimney, made
At local environmental pollution, make the phenomenon that sprinkling around chimney；Second is that having acid since flue-gas temperature reduces in an atmosphere
Property liquid condenses out from flue gas, causes to corrode to equipment and building.
Summary of the invention
