First, the application of environmental protection lime kiln
Active lime has been widely applied to steel making. Silicate slag or fluorite, and other traditional materials used in the steel making process, its effect has been unable to meet the needs of the steel market. To speed up the process of steel making slag-forming speed.
Active lime small bulk density, porosity and a large surface area, high chemical purity, so it has high activity. Use active lime Oxygen can shorten the time, the molten steel to improve yield, reduce the consumption of lime, and can improve the desulfurization, dephosphorization effect, to improve the quality of steel plays an irreplaceable role in the converter steel making.
Active lime for steel making slagging agent is doing while molten sulfur, phosphorus and other harmful substances removed, improving the quality of steel making. With the development of smelting technology and some of the special requirements of steel, in steel production, requiring rapid melting into the furnace of lime in the slag, slag has a faster rate into the earlier formed high alkalinity slag. Therefore, the level of activity and quality of lime, has a direct impact on steel production.
Second, the new environmental protection lime kiln equipment advantages
CHAENGH new environmental protection lime kiln equipment has an absolute advantage in the quality and activity of other products, it is the ideal new lime kiln equipment.
CHAENG lime kiln advanced structure, low loss vertical preheater can effectively improve preheating, increase productivity, they produce very good quality lime. Under the same conditions, the activity of lime shaft kiln lime production is higher than the average high 30ml, activity of up to 400ml, or even higher. In addition, the material in the kiln even rolling forward, uniform heating, uniform product quality, raw burnt burn rate <8%, raw, burnt a lower rate for calcined lime with high activity.
Third, the calcination process
Qualified limestone (20-50mm) by Lifting and carried into the preheater at the top of the silo.
Preheater top two upper and lower hopper level meter to control the feed amount, and then blanking tube limestone evenly distributed to each of the preheater chamber.
Limestone in preheater kiln flue gas is heated to about 1150 ℃ 900 ℃, about 30% decomposition. Hydraulically putted into the active lime rotary kiln, rotary kiln calcined limestone is decomposed into CaO and carbon dioxide.
After the decomposition of limestone into the cooler in the cooler was bubbled into the cold air cooled to below 100 ℃ discharged. By heat exchange 600 ℃ hot air into the kiln and gas co-firing.
The exhaust manifold through the cooler into the bag filter through the induced draft fan, and then the exhaust fan into the chimney.
A lime cooler by vibrating feeder, bucket chain conveyor, bucket elevator, belt conveyor into the lime finished products.
Fourth, how much environmental protection lime kiln equipment
CHAENG has nearly 60 years of experience in large-scale rotary kiln production, leading manufacturing standards, improve service, to win the trust of customers throughout the country. Hua Yan ore source materials company 400,000 tons of nano calcium carbonate production line selecting CHAENG turnkey construction machinery, the partnership marks CHAENG new applications in the lime kiln taken a solid and important step.
