Lime vertical kiln, just like itsname, the shape is erect. It is used for calcination limestone. Due to has lowenergy consumption, less cover area, less investment, wide applicability fuel,and more advantages, it was widely used in metallurgy, construction materials,calcium carbide, Nanometer calcium carbonate, aerated concrete, sugaring, etc.The vertical kiln was manufactured by ZK group with modern new technology, whichis an environment protection, save energy, higher machanization andautomaticity, quite modern lime kiln. Because it adopts the modern technology,make full use the cheap energy, especially pollution of gas for environmentharmful( such as conventer gas, blast furnace gas, calcium carbide furnace tailgas) as the energy, turn waste into wealth. Thus will protect the environment,and produce the high quality lime with lowest cost. To use this new technologyenterprise, economic benefits have increased significantly.
It should be pointed out that thekiln type especially suitable for the production Nanometer calcium carbonate.Investigate its reason that the concentration of CO2 in flue gas jet can reachmore than 35%, CO2 recovery cost is low.
1.Save energy;There are preheatingzone, calcination zone, cooling zone from the top to bottom of kiln inside. Thecooling air blow into the cooling zone from the bottom, though the heattransfer, the goods were cold, and the cooling air was heated, then put intothe calcination zone with the heat for burning, thus reduce the energyconsumption. The flue gas from the fuel after calcination enter into thepreheating, make the material heat to pre-dissociation temperature. The fluetemperature fall to 170-300℃, thencome out from the kiln.
2.The shell of kiln use four layerrefractory in vertical masonry, good effect of thermal insulation, thetemperature of shell will be controlled higher 60℃ than environment, save energy remarkably.
3.Long service life of refractory,the material not directly crash the work surface of refractory, but itsfraction with work surface by gravity setting. Thus it greatly reduces the wearrate of refractory, the refractory will be used in 6-10 years in normally.
4.Less cover area, because thevertical kiln in vertical layout, feeding use the single bucket elevator inhigh angle layout, each functional area is decorated compact, greatly reducesthe cover area.
