Abstract
The utility model provides a chimney with a heat energy recovery device. The chimney with the heat energy recovery device comprises the chimney with the heat energy recovery device. Heat energy recovery equipment is arranged on the lower portion of the chimney, after smoke tangentially enters into a gas collection tank of the heat energy recovery equipment and enters into the heat energy recovery equipment, the smoke and medium in the heat energy recovery equipment conduct indirect heat transfer, the medium is drained from an outlet on the upper portion after heated, after the smoke removes fogdrop in the smoke by a defroster on the upper portion of the heat energy recovery equipment after cooled, and the smoke enters into the upper portion of the chimney and is drained from an outlet of the chimney. The chimney with the heat energy recovery device enables heat energy in the smoke to be recovered as far as possibly, reduces investment of the heat energy recovery device, and simultaneously increases weight of the lower portion of the chimney, and stabilizes the foundation of the chimney.
Description
Affiliated technical field
The utility model relates to a kind of chimney with heat-energy recovering apparatus.This device is mainly used in incinerator, chemical field.
Background technology
At present, in the incinerator system, fume afterheat often adopts waste heat boiler to reclaim, and generally about 150 ℃, when not containing corrosive gas in the waste gas, the flue gas off-energy is larger for the Economizer of Heat Recovery Boiler outlet temperature; Because chemical emission concentration often changes, so the economizer exit temperature often is higher than 150 ℃, also can cause the loss of heat energy; In the waste gas accumulation of heat is burned, when exhaust gas concentration is low, in the time of need not waste heat boiler being set, general direct discharge also causes the loss of heat energy, when adopting heat transmission equipment recovered flue gas heat energy, because flue-gas temperature is not high, little with the temperature difference of heat transmission equipment, so the diameter of heat transmission equipment is little, but length need very longly just can reach heat transfer effect.
Summary of the invention
In order to overcome existing issue, the utility model provides a kind of chimney with heat-energy recovering apparatus, and it comprises a cover chimney, is provided with energy recovery equipment in the chimney passage, this device has utilized the characteristics that Diameter of chimney is little and length is enough, and heat-energy recovering apparatus and chimney are fully combined.
The technical scheme that its technical problem that solves the utility model adopts is: the chimney bottom is provided with energy recovery equipment, flue gas and medium adopt heat exchange mode indirectly, the heat-energy recovering apparatus import is provided with plenum chamber, flue gas tangentially enters heat-energy recovering apparatus bottom plenum chamber, the plenum chamber base plate has constant slope, plenum chamber is provided with sewage draining exit, the heat-energy recovering apparatus heat exchanger tube stretches out fixed head, pipe is outside equipped with sewage draining exit, be provided with thermocouple in the outlet of heat-energy recovering apparatus thermal medium, by outlet temperature control medium flow, the heat-energy recovering apparatus outlet is provided with demister, and heat-energy recovering apparatus links to each other by the concentric reducer of flange with chimney top.After flue gas tangentially enters the plenum chamber of energy recovery equipment, enter energy recovery equipment, flue gas and medium carry out indirect heat exchange in energy recovery equipment, discharge from lower part outlet behind the dielectric heating, cooled flue gas is through being arranged on the demister of energy recovery its upper side, after removing flue fog drip, enter chimney top, discharge from chimney breast.
The beneficial effects of the utility model are: so that the heat energy of flue gas reclaims as far as possible, reduced the investment of heat-energy recovering apparatus, increased simultaneously the weight of chimney bottom, the basis of having stablized chimney.
