According to the lime rotary kiln residue heat recovery device, the low-temperature smoke exhaust sensible heat of the vertical preheater and the radiation heat of the outer surface of the kiln body of the rotary kiln are combined organically, the two kinds of residue heat are recovered effectively, meanwhile, the heat pollution to the environment around is reduced greatly, and an effective approach for the energy conservation and emission reduction of the lime production enterprise is provided further.
Description
Technical field
The utility model relates to a kind of heat recovery device of lime rotary kiln.
Background technology
In lime is produced, use rotary kiln widely to CaCO
3The solid high temeperature chemistry is handled, and makes it be decomposed into CaO.In this production technology, the exhaust gas temperature of shaft preheater is generally about 160 ℃, because the flue gas quality is lower, it is very poor to use economy, basically all is to discharge after the direct dedusting at present.On the other hand, the temperature of rotary kiln outer surface is up to 250～370 ℃, kiln hood zone even sometimes above 400 ℃; Because whole kiln external surface exposes in atmospheric environment; This part heat does not obtain utilizing yet, and has caused very big energy waste, has caused the thermal pollution of surrounding environment simultaneously yet.
The utility model content
The purpose of the utility model provides a kind of lime rotary kiln waste-heat recovery device that makes full use of lime rotary kiln outer surface heat.
To achieve these goals; Adopt following technical scheme: a kind of lime rotary kiln waste-heat recovery device, comprise rotary kiln, it is characterized in that: the outer surface of said rotary kiln is provided with Packed cylindrical shell chuck; The kiln tail of rotary kiln links to each other with preheater; The cylindrical shell chuck is provided with air inlet near kiln tail one end, and the cylindrical shell chuck is provided with air outlet near kiln hood one end, and preheater links to each other with air inlet through pipeline; Air outlet links to each other with the primary dust removing device through pipeline, is connected with waste heat boiler after the primary dust removing device.
In order further to carry out dedusting, reduce atmosphere pollution, be connected with the two-stage dust removal device after the said waste heat boiler.
For ease to the dedusting in the cylindrical shell chuck, said rotary kiln body is for being obliquely installed, and the bottom of lower cylindrical shell chuck is provided with flue-dust retainer.
Keep sealing through preceding sealing device and back sealing device between said cylindrical shell chuck and the rotary kiln body.
Said primary dust removing device is the inertial dust collection device, and said two-stage dust removal device is bag-type dust collector or electric dust collector.
Low-temperature flue gas and rotary kiln external surface radiant heat for the shaft preheater discharge that all can't effectively reclaim at present; The utility model has carried out organic combination with these two kinds of waste heats; Realized effective recovery to these two kinds of waste heats; Greatly reduced simultaneously thermal pollution, a valid approach is provided for further realizing the energy-saving and emission-reduction of lime manufacturing enterprise to surrounding environment.
