Abstract
The utility model discloses a calcining kiln, in particular to an energy-saving thermal storage calcining kiln. The calcining kiln comprises a furnace; a feed inlet is arranged in the upper end of the furnace; and a discharge port is arranged in the lower end of the furnace. The calcining kiln is characterized in that the furnace is provided with double furnace bodies; a reversing system is arranged on the upper part of each of the furnace bodies; and passages used for intercommunication are arranged on the lower parts of the furnace bodies. The beneficial effects of the calcining kiln are that the calcining kiln is formed by the double furnace bodies, and reversing systems are arranged on the upper parts of the furnace bodies and used for alternatively using the two furnace bodies; the intercommunicated passages are arranged on the lower parts of the furnace bodies, so exhaust gas enters a non-combustion cylinder from a combustion cylinder via the intercommunicated passages; and the exhaust gas conducts heat to a raw material layer in the non-combustion cylinder. The calcining kiln is high in heat efficiency; dressed stone in furnace cavity is relatively stable and difficult to break; and calcining quality is good.
Description
Technical field
The utility model relates to a kind of calcining kiln, especially relates to a kind of energy-saving thermal storage calcining kiln.
Background technology
Current calcining kiln, because the heat insulation effect of kiln is poor, in burner hearth, building stones are unstable, easily broken, and not only burning is large, and carry-over loss is large, and combustion rate is low, and capital expenditure is large, and burning is large, and material calcining is inhomogeneous.
Therefore, to those skilled in the art, invent a kind of building stones stable, be not easy fragmentation, combustion rate is high, and the calcining kiln that combustion efficiency is good becomes a kind of problem demanding prompt solution.
Summary of the invention
The utility model proposes a kind of energy-saving thermal storage calcining kiln, this energy-saving thermal storage calcining kiln, the thermal efficiency is high, and in burner hearth, work stone is relatively stable, is difficult for fragmentation, and burning quality is good.
The utility model solves the problems of the technologies described above adopted technical scheme as described below:
A kind of energy-saving thermal storage calcining kiln, comprises kiln, and kiln upper end is provided with charging aperture, and lower end is provided with
Discharging opening, is characterized in that: described kiln is two kiln bodies, and kiln body is provided with exchange system, and the bottom of kiln body is provided with the passage for intercommunication.
Further, preferably scheme is: in described exchange system, be provided with burning gases air blast.
Further, preferably scheme is: on described passage, be provided with cooling gas blower.
Further, preferably scheme is: in described kiln body, be provided with the burner noz(zle) for injection reduction agent.
The beneficial effects of the utility model are: energy-saving thermal storage calcining kiln of the present utility model is comprised of two kiln bodies, and exchange system is arranged at the top of kiln body, for replacing rotation, use two kiln bodies.In kiln body bottom, there is no the passage of intercommunication.Waste gas enters non-combustion barrel by interface channel from combustion barrel; Flue gas conducts heat to raw material layer in non-combustion barrel.The thermal efficiency is high, and in burner hearth, work stone is relatively stable, is difficult for fragmentation, and burning quality is good.
