Ceramic kiln comprises preheating zone, firing zone, quench zone, slow cooling district and the fast cold-zone of kiln tail successively, hot air temperature in the slow cooling district kiln of ceramic kiln, still 250-300 DEG C is reached, waste heat has generally all been dissipated in vain, fail effectively to be used, and firing zone kiln and Spraying Dryer of Ceramics and hot-blast stove etc., all need again hot blast to carry out oxygen enriching burning-aid, need to develop a kind of can the energy-saving structure of heat energy in the kiln of efficiency utilization fast cold-zone.
Summary of the invention
The technical problem to be solved in the present invention, the efficient heat energy being to provide slow cooling district on a kind of ceramic kiln utilizes structure, and heat utilization rate is higher, can realize better energy-saving effect.
For solving the problems of the technologies described above, technical scheme of the present invention is: provide the efficient heat energy in slow cooling district on a kind of ceramic kiln to utilize structure, along the top of slow cooling district kiln, be provided with the A hot gas path of box-type, traverse the cavity of slow cooling district kiln along slow cooling district kiln, be provided with some vacuum heat conduction pipes, the two ends of every root vacuum heat conduction pipe, stretch out the both sides, front and back of slow cooling district kiln respectively, and be upwards communicated with A hot gas path;
The top of slow cooling district kiln, be provided with and somely take out heat pipe, all heat pipes of taking out all extend along slow cooling district kiln afterbody to the direction of head, and every bar takes out heat pipe all through some defeated heat pipes vertically, is communicated with the cavity of slow cooling district kiln;
Along the bottom of slow cooling district kiln, be provided with the B hot gas path of some.
On ceramic kiln as above, the efficient heat energy in slow cooling district utilizes structure, all terminals of taking out heat pipe bearing of trend, and is positioned at the A hot gas path head end of slow cooling district kiln head, is all communicated with hot gas delivery trunk.
On ceramic kiln as above, the efficient heat energy in slow cooling district utilizes structure, the tail end of all B hot gas paths, is all communicated with the hot gas efferent duct of fast cold-zone kiln, and the head end of all B hot gas paths, is all communicated with the hot gas path on the kiln of quench zone.
Said structure is due to can by the hot gas of slow cooling district and fast cold-zone kiln, pumping of heat pipe and hot gas path is taken out by some, realize the superposition of heat, hot gas is heated up, finally be transported to firing zone kiln and the oxygen enriching burning-aid such as Spraying Dryer of Ceramics and hot-blast stove, heat utilization rate is higher, can realize better energy-saving effect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the schematic front view of described embodiment kiln;
Fig. 2 is the schematic top plan view of described embodiment kiln;
Fig. 3 is that the A-A of Fig. 1 is to sectional view.
Detailed description of the invention
See Fig. 1-Fig. 3, the efficient heat energy in slow cooling district on a kind of ceramic kiln is provided to utilize structure, the front and back in slow cooling district are connected with fast cold-zone with firing zone respectively, along the top of slow cooling district kiln, be provided with the A hot gas path 1 of box-type, traverse the cavity of slow cooling district kiln along slow cooling district kiln, be provided with some vacuum heat conduction pipes 2, the two ends of every root vacuum heat conduction pipe 2, stretch out the both sides, front and back of slow cooling district kiln respectively, and are upwards communicated with A hot gas path 1;
The top of slow cooling district kiln, be provided with and somely take out heat pipe 3, all heat pipes 3 of taking out all extend along slow cooling district kiln afterbody to the direction of head, and every bar takes out heat pipe 3 all through some defeated heat pipes 4 vertically, is communicated with the cavity of slow cooling district kiln;
All terminals of taking out heat pipe 3 bearing of trend, and A hot gas path 1 head end being positioned at slow cooling district kiln head, be all communicated with hot gas delivery trunk 5;
Along the bottom of slow cooling district kiln, be provided with 7 B hot gas paths 6, the tail end of all B hot gas paths 6, be all communicated with the hot gas efferent duct 7 of fast cold-zone kiln, the head end of all B hot gas paths 6, is all communicated with the hot gas path on the kiln of quench zone.
During kiln work:
See Fig. 1-Fig. 3, some vacuum heat conduction pipes 2 set on slow cooling district kiln, all by the hot gas of kiln inner chamber, can be sent in A hot gas path 1, realize the superposition of first order heat, simultaneously, slow cooling district kiln afterbody is to the hot gas of the kiln inner chamber of head, being transported to it through some defeated heat pipes 4 be communicated with separately takes out in heat pipe 3, all hot gas taken out in heat pipe 3, hot gas after superposing with first order heat in above-mentioned A hot gas path 1, mix in hot gas delivery trunk 5, realize second level heat superposition, the hot gas heated up after the heat superposition of the second level, exported by blower fan supercharging through hot gas delivery trunk 5, can be used for oxygen enriching burning-aid etc. in firing zone kiln and ceramic hot-blast furnace and spray drying tower, thus efficiency utilization can be reached to the heat energy of slow cooling district kiln, realize better energy-saving effect.
