Detailed description of the invention
See Fig. 1, a kind of ceramic kiln can recycled waste heat is provided, ceramic kiln comprises preheating zone successively, firing zone, quench zone, slow cooling district, region of no pressure and the fast cold-zone of kiln tail, wherein the top of slow cooling district kiln is provided with the A blower fan 1 of two serial connections, run through the top of slow cooling district kiln, be provided with an air inlet pipe 2, the below air inlet of every platform A blower fan 1 all communicates with air inlet pipe 2, the top exhaust outlet of every platform A blower fan 1 all communicates with an exhaust duct 3, (the structure about slow cooling district described herein that exhaust duct 3 communicates with firing zone kiln, the applicant obtains utility model patent, the patent No. is: CN201120153478.X).
See Fig. 1-3, the top of kiln tail fast cold-zone kiln, laterally be provided with the inlet manifold 4 of a hot gas, it communicates with kiln tail fast cold-zone kiln, and after the B blower fan 5 of two serial connections, be connected with some lower appendixs 6 of slow cooling district kiln furnace bottom are vertical, the hot gas in the kiln of kiln tail fast cold-zone pumps to all lower appendixs 6 through B blower fan 5, and all lower appendixs 6 are all laterally extending to the direction of preheating zone kiln furnace bottom along cold-zone kiln furnace bottom of postponing.The top of firing zone kiln, be provided with an one-level efferent duct 7 communicated with Ceramic Dryer, its underpart is connected with through all lower appendix 6 of firing zone kiln furnace bottom is vertical, like this, part hot gas is transported to Ceramic Dryer by shunting, achieves the oxygen enriching burning-aid to Ceramic Dryer.
See Fig. 1, Fig. 3, through the position of firing zone kiln top on one-level efferent duct 7, be connected with on some, appendix 8 is vertical, all upper appendixs 8 are all along laterally extending to the direction of preheating zone kiln top from firing zone kiln top.Exhaust duct 3, through the position of firing zone kiln top, is also connected with all upper appendixs 8 are vertical.To the hot gas that one-level efferent duct 7 exports, and exhaust duct 3 is discharged to the hot gas in firing zone kiln, is all diverted through all upper appendixs 8 and is fed forward.
See Fig. 1, Fig. 4, preheating zone kiln beginning position, be provided with a secondary efferent duct 9, its underpart is connected with the tail end of all lower appendixs 6 is vertical, its top is connected with all upper appendixs 8 are vertical, like this, through the hot gas that all lower appendixs 6 are carried, the hot gas carried through secondary efferent duct 9 and all upper appendixs 8 realizes converging, and continues to be fed forward through all upper appendixs 8.The tail end of all upper appendixs 8 is after two groups of blower fans of serial connection, communicate with ceramic hot-blast furnace, often organize blower fan and comprise two flows in parallel C blower fan 10 equal with pressure, the hot gas that all upper appendix 8 tail ends are finally discharged, after these two groups of blower fans are pumped, discharge hot blast blast comparatively large, lift is comparatively far away, achieves two pressure boost and oxygen increases of hot-blast stove combustion-supporting.
Because the hot air temperature of kiln furnace bottom and furnace roof all reaches about 600 DEG C, hot gas in all lower appendixs 6 and all upper appendixs 8 is in course of conveying, with the hot gas generation heat exchange of furnace bottom, like this, both can realize heating conveying to the hot gas in all lower appendixs 6 and all upper appendixs 8, hot gas is when one-level efferent duct 7 and all upper appendixs 8 export, and temperature has risen to about 400 DEG C, insulation effect can be played to furnace bottom again, all reach good energy-saving effect.
Above-described embodiment is the preferred embodiments of the present invention, and all structures similar with the present invention and the equivalence done change, and all should belong to protection category of the present invention.
