The specific embodiment

Referring to Fig. 1, the energy saver that can be recycled waste heat on a kind of ceramic kiln is provided, ceramic kiln comprises preheating zone successively, firing zone, quench zone, the 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, the top of running through slow cooling district kiln, be provided with an air inlet pipe 2, the below air inlet of every A blower fan 1 all communicates with air inlet pipe 2, the top exhaust outlet of every A blower fan 1 all communicates with an exhaust duct 3, exhaust duct 3 (the structure about the slow cooling district described herein that communicates with the firing zone kiln, the applicant has obtained utility model patent, the patent No. is: CN201120153478.X).

Referring to Fig. 1-3, the top of the fast cold-zone of kiln tail kiln, laterally be provided with the inlet manifold 4 of a hot gas, it communicates with the fast cold-zone of kiln tail kiln, and after the B blower fan 5 of two serial connections, with some lower vertical being connected of appendix 6 of slow cooling district kiln furnace bottom, the hot gas in the kiln of the fast cold-zone of kiln tail 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 the 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 drier, its underpart and all lower vertical being connected of appendix 6 of passing through firing zone kiln furnace bottom, like this, part hot gas is transported to ceramic drier by shunting, has realized the oxygen enriching burning-aid to ceramic drier.

Referring to Fig. 1, Fig. 3, pass through the position of firing zone kiln top on one-level efferent duct 7, with on some, appendix 8 is vertical, be connected, all upper appendixs 8 are all along laterally extending to the direction of preheating zone kiln top from the firing zone kiln top.Exhaust duct 3 is through the position of firing zone kiln top, also with all upper vertical being connected of appendix 8.To the hot gas of one-level efferent duct 7 outputs, and exhaust duct 3 is divided equally stream and is fed forward by all upper appendixs 8 discharged to the hot gas in the firing zone kiln.
