Wherein:
Pipe grid gas stream to increase efficiency device layer 5, greatly improves airflow uniform distribution and gas-liquid mass transfer, effectively improves the white effect that disappears.
Funnel-cap type liquid trap layer 7 disappears 1 upper and lower level spray liquid of White Tower for flue gas to be isolated, allow flue gas be up to disappear it is white
1 top of tower is contacted with the cooling circulation liquid of top spray, but the cooling circulation liquid of top spray cannot fall within and disappear under White Tower 1
Portion's slurry pool 3.The bottom of device be by the sealing plate for White Tower cross section setting that entirely disappears, prevent to disappear White Tower top cooling circulation liquid from
Fall within White Tower lower slurry pond 3 that disappears.The device further includes the air duct being uniformly distributed on sealing plate, and air duct is set as heavy caliber and one
Determine the circular tube structure of height, the flange of air duct bottom is fastened on sealing plate, corresponding hole is opened by the quantity of air duct on sealing plate,
The flue gas for alloing to disappear in White Tower goes upward to White Tower top that disappears by air duct, reduces the increase of flue gas resistance as far as possible.Air duct is adopted
With the PP material of 10mm thickness, anti-corrosion and wear-resisting property are excellent.Each air duct of the device configures a blast cap, and blast cap is with several
Certain height is arranged in connecting rod sling between air duct side wall, blast cap and air duct upper limb, allows flue gas from air duct and wind
It is walked between cap to 1 top of White Tower that disappears；The projected area of blast cap is greater than the cross-sectional area of air duct, makes the cooling circulation liquid on top not
The lower slurry pond 3 that the White Tower that disappears can be dropped down by air duct avoids mixing with the slurries for White Tower lower part spray that disappears.The device air duct with
Height between blast cap is the channel of the free uplink of flue gas, can be to reduce as far as possible according to the size adjustment of exhaust gas volumn in tower
System flue gas resistance and setting disappear White Tower whole height reasonably as priority principle.The blast cap of the device is small using thicker (16mm's)
Angle circular cone roof construction or polygon cone structure can bear the pressure that upper slurry spray applies, and evacuate the cold of top
But cooling circulation liquid is to sealing plate.
Coolant liquid outlet mouth 8, the top cooling circulation liquid that funnel-cap type liquid trap layer 7 is collected, cannot accumulate in always sealing plate
On, it need to send to the White Tower 1 that disappears, the top cooling circulation liquid spray equipment 10 that can return to the White Tower 1 that disappears after supercooling continues
Spray makes saturated flue gas reducing temperature and humidity, and condensed water is precipitated, and reaches pair that white cigarette and the recycling of flue gas condensing water are eliminated to flue gas
Recast is used.
Corrugated plate dst packing layer 9 uses high-performance PTFE filler, is a kind of corrugated plate dst module product, in a manner of filling
Certain height is accumulated, is arranged between the top cooling circulation liquid spray equipment 10 of the White Tower 1 that disappears and funnel-cap type liquid trap 7.
PTFE filler is heat-resisting, moisture-proof, corrosion-resistant, wear-resistant, cleaning, and corrugated Modular surface can greatly improve connecing for flue gas and spray liquid
Contacting surface product, ripple plate surface forms liquid film under the action of cooling circulation liquid spray, and temperature is lower than saturated flue gas temperature, can accelerate
The moisture content in flue gas is reduced, saturated flue gas reducing temperature and humidity is made, condensed water is precipitated, reaches and eliminates white cigarette and flue gas condensing to flue gas
The double action that water recycles.
Steam disappears white device 11, heats condensed saturated flue gas using the method for spraying into steam, becomes saturated flue gas not
Saturated flue gas improves the degree of unsaturation and flue-gas temperature of flue gas, reaches the white effect that further disappears.
Efficient ridge type demister 12 effectively removes and disappears the drop that the unsaturated flue gas of white device 11 carries by steam, disappears
Except the flue gas band rain phenomenon of chimney breast.
Process flow:
Gas phase: flue gas enters the White Tower 1 that disappears from the smoke inlet 2 of the White Tower that disappears, and is starched by pipe grid gas stream to increase efficiency device 5 and lower part
Liquid spray equipment 6 contacts, and after spraying cooling (flue-gas temperature is higher than slurry temperature), flue gas is fully saturated, by funnel-cap type
The uniformly distributed blast cap of liquid trap 7 goes upward to White Tower top that disappears, and sprays using top cooling circulation liquid, with high-performance PTFE filler 9
Contact reducing temperature and humidity, the condensate liquid in saturated flue gas is precipitated, drop on the sealing plate of funnel-cap type liquid trap 7, saturated flue gas after
Continuous uplink heats up by the steam steam that white device 11 sprays that disappears, and saturated flue gas becomes unsaturated flue gas, using efficient ridge type
Demister 12 removes the steam carried in flue gas, and the flue gas to heat up again by reducing temperature and humidity is drawn from White Tower exhanst gas outlet 4 that disappears.
Liquid phase: saturated flue gas the top of the White Tower 1 that disappears be cooled circulation fluid spray after, flue-gas temperature reduce, with high property
Energy PTFE filler 9 forms liquid film when contacting and comes into full contact with cooling, and the condensate liquid of precipitation drop to the sealing plate of funnel-cap type liquid trap 7
On, it is emitted by coolant outlet 8 outside the White Tower 1 that disappears, is cooled down, recycled again, be back to top cooling cycle
Liquid spray equipment 10 continues to give saturated flue gas spraying cooling.
It is the preferred embodiment of the utility model above, those of ordinary skill in the art can also carry out respectively on this basis
Kind of transformation improves, and under the premise of not departing from the utility model total design, these transformation or improves this reality all should belong to
Within the scope of novel be claimed.
