The utility model content
To the existing in prior technology problem; The utility model provides a kind of ore deposit hot stove flue; This flue mainly improves the flue in the factory building; The gasification cooling flue device replacement that is surrounded by water-cooled and evaporation and heat-exchange tube bank has the steel light pipe flue in the factory building now, and utilizes the water in the heat-exchanging tube bundle constantly to absorb heat rising temperature and finally become steam, to being reclaimed by the residual heat resources in the high-temperature flue gas of discharging in the hot stove in ore deposit.
For realizing above-mentioned purpose; The hot stove flue in a kind of ore deposit of the utility model comprises factory building inner flue, factory building external flue, dust pelletizing system and the chimney that connects successively; The high-temperature flue gas of being discharged by the hot stove in ore deposit enters into the dust pelletizing system dedusting via said factory building inner flue, factory building external flue; Enter atmosphere through chimney again; Said factory building inner flue is the gasification cooling flue device, and said gasification cooling flue device comprises by evaporation and heat-exchange tube bank and surrounds the body flue, is used for the saturation water that the body flue is produced is carried out drum that carbonated drink separates, is used for the saturation water that the body flue forms is input to tedge in the drum, is used for drum water is input to down-comer and carbonated drink header in the body flue; Said evaporation and heat-exchange tube bank links to each other with said carbonated drink header, and an end of said tedge links to each other with the carbonated drink header, and the other end links to each other with said drum; One end of said down-comer links to each other with drum, and the other end links to each other with the evaporation and heat-exchange tube bank.
Further, said evaporation and heat-exchange tube bank is the solid matter heat exchange tube structure.
Further, said evaporation and heat-exchange tube bank is the water-cooling wall heat exchange tube structure.
Further, the outer insulating that also is provided with of said evaporation and heat-exchange tube bank.
Its advantage of the utility model is:
(1) utilize the gasification cooling flue device to replace the steel light pipe flue in the traditional handicraft; Can reclaim the hot fume afterheat in ore deposit and produce steam; And the steam that is produced can be supplied with and produce, live or generating usefulness by second use, has practiced thrift the valuable waste heat energy.
(2) utilize the factory building inner space to derive flue gas outside factory building, and, can save the original surface cooler in back and take up an area of and investment flue gas cool-down.
(3) gasification cooling flue inside is water or saturated vapor, and it is much lower that the working medium temperature is compared flue-gas temperature, and flue is provided with outer insulation, and outside wall temperature is lower than 50 ℃, reduces high-temperature flue gas to the thermal pollution that workman's production environment causes, and avoids potential safety hazard.
(4) especially to the hot stove in closed ore deposit, flue-gas temperature has increasingly high development trend, and the radiant heat proportion of electric furnace flue gas is also increasing, and suitable especially the employing with the radiation heating-surface form is master's gasification cooling flue.
