Such as industrial production, communications and transportation, generate electricity, life cooking stove, heating boiler etc., wherein industrial pollution is one of atmosphere pollution important
Source.
Coal-fired flue-gas after wet desulphurization, can contain substantial amounts of water smoke, in water smoke dissolved with substantial amounts of sulfate and
Finely ground particles, substantial amounts of PM2.5 can be formed into air.
At present, international and national flue gas desulfurization technique mainly uses wet desulfurizing process, and flue gas wet desulphurization process is general
Demister is set on the spraying layer of absorption tower, after the demister demisting, flue fog drip can be removed largely, but to cigarette
Saturation vapour in gas can not just remove, after demisting by smoke stack emission.
If this flue gas is directly discharged by chimney, steam of the wet flue gas after the cold air in touching air in flue gas
Small water droplet can be condensed into, these small water droplets can further adsorb steam and droplet in flue gas, be formed " chimney rain ", due to water droplet
Into acidity, and with solid particulate matters such as sulfate, surrounding enviroment are had a strong impact on, if emptied again by GGH heating, aqueous vapor is led to
When crossing GGH heat-transfer surface, steam, droplet are evaporated, and the sulfate in steam, droplet can be adhered on GGH heat-transfer area, made
Fouling, blocking and a corrosion occur for GGH；If increasing wet electrical dust precipitator, exist and take up an area big, corrosion, operation and maintenance cost
Height, and it is not suitable for small-sized smoke processing system.

Preferably, the flue gas dehumidifying tower is horizontal flue gas scrubber.Flue gas dehumidifying tower is cylindrical, flue gas scrubber
For square tower.
Preferably, the spraying layer is provided with three layers of sprinkling equipment, in vertical flue gas scrubber, arranges from the bottom to top, often
Layer sprinkling equipment between be provided with a certain distance, it is preferable that three layers of sprinkling equipment be arranged on vertical flue gas scrubber it is upper, in,
Bottom.
Preferably, the bottom of the chimney is provided with blower fan.The gas of flue gas dehumidifying tower is imported into chimney discharge.
Preferably, the bottom of the flue gas scrubber is provided with spray liquid collecting region.
Preferably, spray liquid circulating line is provided between spraying layer and the spray liquid collecting region.Circulated successively
Spray, the medicament of disengaging can be added directly in spray liquid collecting region.
Preferably, the bottom of the dehumidifier is provided with draining valve.
Preferably, the adsorption layer includes multiple adsorbent equipments, and each adsorbent equipment is detachably mounted on adsorption layer
It is interior.Adsorbent equipment is arranged to drawer type, three layers of conventional arrangement, rises to five layers of adsorbent equipment as needed.Can not shut down into
Row is changed.
Preferably, the top of the flue gas scrubber is provided with detection hole, for detecting the composition of flue gas, so as to according to circumstances
The number of plies of adsorbent equipment is set.
The beneficial effects of the utility model are that do not have by the flue gas of fume desulfurizing tower of the present utility model, flue gas dehumidifying tower
There are " white cigarette " and PM2.5, the spy such as the device desulfurization effect on moisture extraction is good, efficiency high, investment low, operating cost is low, non-secondary pollution
