Coal preparation is an important part of the use of coal active lime kiln system. Generally, there are two systems, one is wind swept coal mill and tube mill bag filter composed of the coal preparation system, which is easy to operate, clean environment and so on. Its production process is as follows: Block of coal ≤25mm enhance the process is supplied to the bucket belt, lime kiln equipment, and then enter the coal storage by the belt through the lower portion of coal storage disc feeder or electromagnetic vibrating feeder feed MILLS, Shijiazhuang lime kiln plant, the mill is a grinding, drying in one device, kiln equipment manufacturers, while in grinding or the auxiliary combustion chamber through the hot air from the kiln system The hot flue gas to dry. Containing gas from pulverized coal mill out of the exhaust fan in the pumping force, after entering separator separating coarse particles of pulverized coal cinder valve automatically returns through mill grinding again, and powder in the air flow drive into the bag filter dust collector, to achieve the purpose flour gas separation. A gas separator, and after the dust collection purification of exhaust from the exhaust fan, part of the exhaust gas bubbled recycling mill, another part of the exhaust gas through the chimney into the atmosphere. Collected by the dust collector down pulverized coal is discharged into the kiln before pulverized coal silo. By the coal storage needed by a Roots blower before being fed into the kiln burner, combustion air through the burner for combustion air blower, environmental protection lime kiln equipment prices for calcination of limestone use. The main task of the kiln furnace regularly discharged sewage is deposited in the furnace slag, so regular discharge point should be selected in the largest part of the water residue concentration, which is the lowest part of the furnace, as the tanks or the old furnace of mud Drum place. Periodic emissions of how much depends on the quality of water is generally performed once every 24h, but if the furnace is clean condensate water, add water with a small amount of chemical demineralized or softened water at regular intervals can be greatly sewage extended. Regular Blowdown specific interval and duration of the operation is based on a chemical plant boiler water quality dependent. Automatic control is an important feature of the new technology lime kiln, its feeding, ingredients for wind, gas, cinder is through the end of the computer-controlled automation. However, we should ponder national conditions, plant intelligence, and the value of capital, nor is it as high as possible degree of automation should end with the role as a criterion in the actual production, lime kiln firing is not an ideal world, the limestone surface at 810 ~ 850 ℃ begins to decompose, and the inner surface of CaO due to the decomposition of the pores filled with decomposition precipitated CO2, the inner layer of limestone kiln gas CO2 partial pressure ratio high decomposition temperature is correspondingly higher. Therefore constantly drawn by suction fan kiln gas, take negative pressure operation, accelerate the decomposition rate of CaCO3 can be shortened limestone in the kiln firing zone residence time.
