For transparent grp.
The mechanism of waste heat recycling and dedusting cooling of the invention is: the left section of chimney surface is provided with closed spiral shape
Guide apparatus, guide groove top water inlet are connected to lower water inlet pipe, and adopting boiler chimney waste-heat is recycled using the water in guide groove, then
The high-temperature water of preheating injects boiler by outlet pipe；There are two the right section of chimney top settings is used to the spray head that dedusting cools down,
And spray head is tilted to the left certain angle, increases the water mist of spray head ejection and contact area and the time of contact of smoke evacuation, due to
The process of mass transfer and heat transfer occurs in gas and liquid contact process simultaneously, therefore the dust-extraction unit both has dustproof function,
Have the function of flue gas cool-down again and absorbs pernicious gas；Since right section of chimney is oblique, sewage can be arranged by fistulae
Out；A small amount of smoke evacuation enters fistulae in order to prevent, is provided with anti-cigarette case and returns smoke pipe, the sewage in fistulae passes through after flowing into anti-cigarette case
The sewage pipe of anti-bottom of cigarette box is discharged, if a small amount of smoke evacuation enters anti-cigarette case by fistulae, can be reentered by returning smoke pipe
Right section of chimney；The effect of left smoke deflector in the right section of chimney is to prevent direct rushing nozzle of discharging fume, the effect of right smoke deflector
It is to prevent the smoke evacuation in right section of chimney from entering back smoke pipe and the cigarette being discharged in smoke pipe is discharged smoothly upwards.
Peace is convenient in adopting boiler chimney waste-heat recycling dedusting cooling device provided by the invention and its application method, environmental protection and energy saving
It fills, is at low cost, it, can be effective by that can realize the effect of waste heat of chimney recycling and dedusting cooling simultaneously to water inlet manifold water delivery
Solution exhaust gas temperature is excessively high, waste heat of chimney waste, waste of fuel is serious, the easy high-temperature oxydation of chimney rots, boiler exhaust gas is dirty
Contaminate the excessive problem of object.
