Abstract
The utility model relates to the field of energy-saving technology in sintering process, in particular to a low-temperature waste gas recovery device of a sinter cooler, and is characterized in that the device comprises a hot air hood arranged on the low-temperature section of the sinter cooler, a hot air hood arranged at the tail part of a sintering machine and a hot air pipe, the two hot air hoods are connected with each other through the hot air pipe, and a blower is arranged on the hot air pipe. Compared with the prior art, the utility model has the benefits as follows: firstly, residual heat of low-temperature hot waste gas in the sinter cooler can be recovered, so as to reduce environmental pollution of the emission of the low-temperature hot waste gas; secondly, the temperature of flue gas of a wind box at the tail part of the sintering machine can be increased; and thirdly, the utility model ensures that fuel consumption for sintering solids can be properly reduced under the premise that the temperature of flue gas in the main exhaust blower of the sintering machine is not lowered.
Description
Technical field
The utility model relates to the field of energy-saving technology of sintering process, relates in particular to a kind of sinter cooler low temperature waste gas retracting device.
Background technology
The high-temp waste gas of sinter cooler adopts the mode of producing steam or generating to carry out heat recovery at present, in warm waste gas adopt hot gas sintering or homogeneous sintering processing to recycle, the low temperature hot waste gas is not then recycled and directly outer draining in the atmosphere, along with putting more effort of energy-saving and emission-reduction, the recycling of low temperature hot waste gas also should be studied, reach the recovery cryogenic waste heat resource, alleviate the purpose of environmental pollution.
Summary of the invention
The purpose of this utility model provides a kind of sinter cooler low temperature waste gas retracting device, and the low temperature hot waste gas on the sinter cooler is used.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of sinter cooler low temperature waste gas retracting device comprises the air bells cap that is arranged at the sinter cooler low temperature section, the air bells cap and the hot air duct of sintering machine afterbody, and two air bells caps connect by hot air duct.
Described hot air duct is provided with blower fan.
Compared with prior art, the beneficial effects of the utility model are: 1) can reclaim the residual heat resources of low temperature hot waste gas in the sinter cooler, alleviate the low temperature hot waste gas and efflux pollution to environment; 2) can improve the flue-gas temperature of sintering machine afterbody bellows; 3) guaranteeing suitably to reduce sintering solid burnup under the prerequisite that sintering machine main exhauster flue-gas temperature does not reduce.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-sinter cooler 2-sintering machine 3-air bells cap 4-hot air duct 5-blower fan
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, a kind of sinter cooler low temperature waste gas retracting device comprises that the air bells cap 3 that is arranged at sinter cooler 1 low-temperature zone, air bells cap 3 and 4, two air bells caps of hot air duct of sintering machine afterbody connect by hot air duct 4.Hot air duct 4 is provided with blower fan 5.The low temperature hot waste gas of sinter cooler 1 low-temperature zone is collected through air bells cap 3, walks to sintering machine 2 afterbodys along hot air duct 4, and the sintering bed that passes sintering machine enters the main exhausting system of sintering machine, and blower fan 5 can improve the collection efficiency of low temperature hot waste gas.
The utility model can reclaim the residual heat resources of low temperature hot waste gas in the sinter cooler, 1) alleviate the low temperature hot waste gas and efflux pollution environment; 2) can improve the flue-gas temperature of sintering machine afterbody bellows; 3) guaranteeing suitably to reduce sintering solid burnup under the prerequisite that sintering machine main exhauster flue-gas temperature does not reduce.
