Description
Technical field
The present invention relates to flue gas desulfurization application field, more particularly to a kind of flue gas of slurries cooling mixes wind and disappeared white system.
Background technology
The industry such as existing electric power, steel, biochemistry flue gas, tail gas are typically all by the processing equipment such as desulfurization, out of stock.It is especially electric
After minimum discharge transformation is crossed in Lixing already, determine Con trolling index for flue dust, sulfur dioxide, nitrogen oxides, mercury and mercuric compounds 4
Index, emission limit are respectively 10mg/m3、35mg/m3、50mg/m3、0.03mg/m3, some areas require soot emissions limit value
For 5mg/m3.Say that the elimination to pollutant has been greatly improved from environmental angle.
Existing flue gas, tail gas pass through wet desulphurization or spray column mostly, are generally carried out using Gypsum Wet technology
Flue gas desulfurization is handled.However, saturation is substantially at using the steam in the flue gas after the Wet technique desulfurization such as limestone-gypsum
State, water capacity is big, and in discharge process, flue gas is reduced mixing in diffusion process temperature with air, and the elutriation in flue gas goes out, in cigarette
Chimney periphery forms white haze, is commonly called as " plume ".The flue gas or exhaust temperature of discharge are low, water capacity is big, can not effectively spread, and promote mist
The formation of haze, civil plantation and vision are caused to perplex.
These enterprises are usually present " emitting white cigarette " phenomenon in process of production, the reason for this caused phenomenon：Saturation
Flue gas is by the relatively low air quick refrigeration of temperature, and vapor is condensed into liquid in flue gas, and condensing water droplet produces refraction to light, dissipated
The decline of flue gas light transmittance is penetrated, so that plume shows white, forms white plume, but as the diffusion of flue gas is by atmospheric dilution
White cigarette is gradually reduced until disappearing afterwards.
To eliminate white cigarette, prior art mainly sets flue gas temperature rise heat exchanger between desulfurizing tower and chimney, by carrying
Flue-gas temperature is risen to solve " plume " problem caused by condensation of moisture in flue gas, but effect is all not so good, is primarily due to：
(1) steam is saturated mode in flue gas, and water capacity is big, and flue gas heating thermic load is huge；
(2) existing flue gas temperature rise heat exchanger is mostly fin-tube heat exchanger, and heat transfer efficiency is low, and floor space is big, Wu Faman
The existing place transformation of foot requires；
(3) contain a certain amount of gypsum particle in the flue gas after desulfurization, be easy to block heat exchanger；
In addition, such as only by added between desulfurizing tower and chimney flue gas condenser or flue gas heater to dehumidify,
Heating, due to containing Korrosionsmedium in flue gas, easily causes flue gas heat-exchange unit corrosion failure.
The content of the invention
Eliminate white " plume ", core is to reduce the mistake of steam discharge capacity and lifting flue gas China vapor in flue gas
