In order to reduce soot emissions, someone has adopted calcining kiln, it is that coal is placed in the lateral combustion chamber of rectangular kiln body, is blown in the kiln body with the firepower of blower fan with coal combustion, and what it adopted is a kiln one stove formula, only leave flame-observing hole at both direction, advance fire in a direction, firepower is even inadequately, and it is better to burn the building stones quality that near the place of burner, building stones away from the place of burner can not become lime, and the common roasting kiln of rate ratio is also low.Have only a fireclay crossbeam in the high temperature storehouse of this calcining kiln, support with fire bars between crossbeam and the kiln body, be blown as crossbeam in use, material in the kiln and fire bars just all fall down, and can't produce again.Ore after high-temperature calcination is directly come out of the stove, and is exposed to physical environment, causes heat to distribute, and has wasted the energy.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of can improving product quality and yield, and over-emitting black exhaust not during production can reach the environmental-protection energy-saving lime incineration kiln of discharging standards.

For solving the problems of the technologies described above the technical solution adopted in the utility model be: it comprise the kiln body and in intravital preheating storehouse, the high temperature storehouse that is provided with from top to bottom of kiln, go out the bed of material, in the high temperature storehouse and go out to be provided with the accumulation of heat storehouse between the bed of material, the high temperature storehouse is circumscribed with gas furnace.

The high temperature storehouse is cylindrical, is evenly equipped with to be divided into 16 fire jetting holes of two-layer layout up and down on its bulkhead, and fire jetting hole is communicated with gas furnace, is evenly equipped with 8 flame-observing holes between two-layer fire jetting hole, and this flame-observing hole also is a blanking port.

4 to 10 outriggers are installed below the high temperature storehouse, outrigger is stretched out to the center by the kiln wall, settles circular ring type fireclay crossbeam on the outrigger, staggered arrangement fireclay fire bars between the fireclay crossbeam, the fireclay fire bars is for arch form upwards, by annular and radial fire bars staggered arrangement.

The technical progress that the utility model is obtained is: utilize gas furnace to convert coal to coal gas, Wingdale is calcined for coal with gas, coal gas is through secondary combustion, reduced the discharging of flue dust, heat also is fully used, make in the production area that no longer black smoke is billowing, because firepower is more prosperous and even, output also improves greatly; The accumulation of heat storehouse that increases newly makes insufficiently burnt ore can continue insulation in the accumulation of heat storehouse and becomes ripe.Through repeatedly quality product being chemically examined, reached user's requirement fully.The profile in high temperature storehouse changes the garden cylindricality into and makes and do not have the dead angle in the storehouse, and temperature is even in the storehouse; On eight directions, be equipped with flame-observing hole, can clearly observe the changing conditions of the material calcining of the intensity of a fire in the storehouse and each several part, accomplish timely blowing, improved output; But each flame-observing hole is blowing all, has also alleviated labor strength.Nearly 16 of the quantity of fire jetting hole of the present utility model are symmetrically distributed intensity of a fire correlation, and the two-layer fire hole flame of being separated by is up and down arranged, strengthened the incinerating volume, made that the building stones at each position all obtain full and uniform calcining in the kiln, accelerated production rate and helped the raising of quality product.Fire bars of the present utility model is placed between the annular crossbeam, and the circular ring type crossbeam places again on the some outriggers that stretched out below by the high temperature storehouse, even wherein an outrigger is blown, other outrigger continues to support remaining material, until finishing the production of this kiln; Perhaps ring-like crossbeam fracture also can work on, and can not influence production, up to a suitable maintenance date at once.The fireclay fire bars of staggered arrangement is arch form upwards between the ring-like crossbeam of fireclay, has strengthened the supporting capacity of crossbeam and fire bars, has improved work-ing life.
