It is an object of the present invention to be achieved through the following technical solutions.
Adopting boiler chimney waste-heat reclaims dedusting heat sink and using method thereof, and including left section of chimney and right section of chimney, left section of chimney is provided with waste-heat recovery device, and right section of chimney is provided with dedusting heat sink.
Described left section of chimney surface configuration has closed spiral-shaped guide groove device, and guide groove top water inlet connects with lower water inlet pipe, and guide groove bottom outlet is connected with body of heater water inlet by outlet pipe.
The described right section of inclined shape of chimney, being internally provided with the two pieces of smoke deflectors in left and right, top is provided with two shower nozzles, and shower nozzle water inlet pipe is by flow divider and enterprising cross current, described right section of chimney bottom is provided with fistulae, and fistulae connects with anti-cigarette case, blow-off pipe and time smoke pipe.
Described upper water inlet pipe is connected with water inlet manifold by flow divider with lower water inlet pipe.
Each through the Flange joint being provided with sealing ring between described body of heater and left section of chimney, between left section of chimney and right section of chimney, between right section of chimney and smoke chimney.
Described left section of chimney, right section of chimney and closed spiral-shaped guide groove material are rustless steel, and described anti-cigarette case material is transparent grp.
The mechanism of the waste heat recovery of the present invention and dedusting cooling is: described left section of chimney surface configuration has closed spiral-shaped guide groove device, guide groove top water inlet connects with lower water inlet pipe, utilize the water in guide groove to reclaim adopting boiler chimney waste-heat, then the high-temperature water of preheating is injected boiler by outlet pipe; Described right section of chimney top is provided with two shower nozzles for dedusting cooling, and shower nozzle is tilted to the left certain angle, add the water smoke of shower nozzle ejection and the contact area of smoke evacuation and time of contact, owing to gas and liquid contact process occurring the process of mass transfer and heat transfer simultaneously, therefore described dust arrester had both had dustproof function, has again flue gas cool-down and absorbs the effect of harmful gas; Due to the right section of inclined shape of chimney, sewage just can be discharged by fistulae; In order to prevent a small amount of smoke evacuation from entering fistulae, it is provided with anti-cigarette case and returns smoke pipe, sewage in fistulae is discharged by the blow-off pipe of anti-bottom of cigarette box after flowing into anti-cigarette case, if a small amount of smoke evacuation enters anti-cigarette case by fistulae, it is possible to reenter right section of chimney by returning smoke pipe; The effect of the left smoke deflector in described right section of chimney is to prevent direct rushing nozzle of discharging fume, and the effect of right smoke deflector is to prevent the cigarette that the smoke evacuation in right section of chimney is discharged in entering back smoke pipe and making back smoke pipe from upwards discharging smoothly.
Adopting boiler chimney waste-heat provided by the invention reclaims dedusting heat sink and using method thereof, environmental protection and energy saving, be easily installed, cost low, by just can realize the effect that waste heat of chimney reclaims and dedusting is lowered the temperature to water inlet manifold water delivery simultaneously, can effectively solve the problem that exhaust gas temperature is too high, waste heat of chimney is wasted, waste of fuel is serious, the easy high-temperature oxydation of chimney rots, boiler exhaust gas pollutant are too much.
