Technical field
Disappear white device, specifically a kind of flue gas of wet desulphurization the present invention relates to a kind of wet-method desulfurized fume
Eliminating white smoke chimney.
Background technology
In the combustion heating technique back segment of the industries such as electric power, petrochemical industry, waste incineration, it will usually use wet desulphurization work
The burning such as skill, i.e. boiler, heating furnace, incinerator flue gas out will be by that after desulfurization, could enter smoke stack emission to big compression ring
In border.And through the flue gas after wet desulphurization, one side temperature is drastically reduced, about 110 DEG C of pacts dropped to after desulfurization from before desulfurization
50 DEG C, another aspect flue gas after desulfurization water content is also sharply increased, and is basically reached saturation state and is contained a large amount of droplets.So
Wet flue gas be directly discharged in air through traditional chimney, met in chimney outlet and low ambient temperature air, will drop rapidly
Condensed below to dew point, produce a large amount of droplets, that is, produce visual chimney " emitting white cigarette " phenomenon, serious can also be in chimney week
" chimney rain " is formed in the certain limit of side.
The technology that the elimination wet desulfurization flue gas of main flow emit white cigarette phenomenon is to install cigarette additional on flue before flue gas enters chimney
Gas reheater（GGH）, i.e., the low-temperature flue gas after desulfurization are heated with high-temperature flue gas before desulfurization, low-temperature flue gas is increased to a constant temperature
After degree（Normally about 85 DEG C or so）Again through smoke stack emission, so to meet just be not easy in chimney outlet and surrounding air drops to dew
Below point temperature, " emitting white cigarette " and " chimney rain " phenomenon will not be produced.This eliminating white smoke technology is largely effective, but also has reheating
Device（GGH）It is perishable, block the shortcomings of and deficiency.
Patent " energy-saving environmental protection device and technique of a kind of reduction flue gas white cigarette "（CN 105805768 A）The method of use
It is that low temperature wet flue gas after wet desulphurization and cold air exchange heat, it is lower to be allowed to temperature, and separates out condensed water, is then risen with heat absorption again
Part hot-air after temperature uniformly mixes, and the saturation degree of the mixed gas after mix and convert is reduced, finally again through smoke stack emission to air
In.It is used for the amount with the gas of flue gas mix and convert after control, the method can equally mitigate even elimination white cigarette phenomenon.But the method by
Some hot-airs in mix and convert so that the total exhaust gas volumn by smoke stack emission increases severely, often need chimney redesign plus
Slightly, construction investment is big for some transformation projects.
As shown in figure 1, psychrometric charts of the Fig. 1 for wet flue gas, by means of Fig. 1, in the prior art, eliminating wet desulfurization flue gas
The technology for emitting white cigarette phenomenon carries out qualitative explanation：About 50 DEG C of wet flue gas temperature after general desulfurization, water capacity uses cigarette close to 100%
B points on gas psychrometric chart are represented；Local environment temperature, northern winter is general at -5 DEG C ~ 5 DEG C（Winter most easily forms white cigarette and shows
As）, humidity represents below 40% with the A points on psychrometric chart.When desulfurization wet flue gas are after in smoke stack emission to surrounding air, with
Surrounding air mixes, and mixed gaseous state point C mono- is scheduled on the line of point A and point B.Far and near and mixing apart from B points is first
The ratio of the amount of phase flue gas and institute's ingress of air is inversely proportional.When mixed gas state point C is located at saturation waterline（Relative humidity 100%
Line）When following, i.e., into " fog-zone ", will haze, be formed visual " white cigarette ".
The main stream approach of traditional eliminating white smoke is theoretically, all the position of the state point B for changing chimney outlet wet flue gas
Put, the wet heating such as pass through and rise a high-temperature（The way of GGH）Or dilution dehumidification（The way of patent CN 105805768）Method make B
Away from saturation waterline, state is changed into the B on flue gas psychrometric chart to point’Point.Ensure straight line A B’With saturation waterline without intersection point, you can complete
Totally disappeared except " white cigarette " and " chimney rain " phenomenon.

Compared with prior art, the beneficial effects of the invention are as follows：
Compared with conventional art, because wet flue gas contain huge moisture after desulfurization, want to make the rising of its temperature then need consumption
Huge heat, the method for reducing water capacity using mix and convert dilution then needs the hot-air of mix and convert flood tide, causes the mixed gas can
Can be double, chimney needs overstriking；And the heating of the technology used in the present invention method is air, air humidity content is small, and heating rises
Same temperature high, it is necessary to the heat of consumption is much smaller, further, since wet flue gas are discharged and outside ambient air from chimney breast
Mixing is a mixed process for progressive diffusion, therefore only needs to change the temperature of chimney top export outer partial surrounding air,
Rather than the temperature for changing whole exterior space, required quantity of hot air is simultaneously little.Furthermore, hot-air be outside chimney with
The mixing contact of desulfurization wet flue gas, therefore overall overstriking chimney is not needed, improvement project amount is small.
