Description
Technical field:
The present invention relates to a kind of energy-saving environment-friendly cement clinker preparation system, belong to the cement clinker production field.
Background technology:
At present, only have a raw material grinding mill in the cement slurry preparation process, the raw material production capacity is low, can not satisfy follow-up cement firing system to the demand of raw material, so that follow-up system can not be operated at full capacity the waste resource; The metering precision is low, and the raw meal quality fluctuation happens occasionally, and directly causes the quality of follow-up grog low; Raw material select in the feeding procedure of powder, adopt the blanking scraper-trough conveyer to carry out feeding, the blocking phenomenon occurs easily, and failure rate is high, the steady running that impact is produced; Select powder mostly to adopt centrifugal classifier, and the centrifugal classifier grinding efficiency is low, yield rate is low, cause the mill internal recycle rate of load condensate of raw material grinding mill higher, so just aggravated the power consumption of raw material preparation system, and centrifugal classifier can't satisfy whole cement production system for the requirement of cement slurry quality; During the cement slurry homogenizing, cement raw material homogenizing silo storage capacity is less, the homogenizing ability a little less than, mostly can only lean on the bottom of the reservior strength to blow device and carry out homogenizing, the warehouse compartment of each homogenizing storehouse must be consistent, and can not form Matter Transfer between each storehouse, homogenization method is single, homo-effect is poor, and the raw ingredients fluctuation is larger, has a strong impact on the burning quality of follow-up grog; And to adopt the scheme of independent transformation raw material homogenizing silo, cost of investment is larger, and the transformation cycle is longer; During materiel warehouse-out, only have a chapelet, raising efficiency is low, can not satisfy the feed demand of follow-up system; The raw material measuring chute does not have measuring apparatus, so the raw material amount in the storehouse can't in time learn, is easy to cause the phenomenon of buying securities with all one's capital in operating process, can stop up raw material measuring chute top transfer line when serious; In the cement clinker burning system, adopting air swept mill, coal carries out grinding to raw coal, air swept mill, and coal is provided by hotblast stove, coal dust adopts cyclonic separator to select powder, Pulverized Coal Bin adopts charge level controller to measure, and shortcoming is that hotblast stove raw coal consumption is large, there is certain danger in the coal dust oven dry of the bad control of hot blast temperature causes that air swept mill coal mill, if misoperation has the danger of blast; Adopt the cyclonic separator grinding efficiency lower, yield rate is lower, not only can not satisfy the coal dust supply of whole system, and has increased the circulating load rate of coal dust in coal mill system, and power consumption is larger; Because the isolated fineness of pulverized coal of cyclonic separator is thicker, the coal dust burn-out degree is low when calcined by rotary kiln, and the incomplete combustion of coal dust easily occurs, and has affected the quality of grog in addition; Pulverized Coal Bin adopts the interior bed depth of Pulverized Coal Bin that can only rely on of charge level controller to calculate the amount of material in the storehouse, Measuring Precision is not high, it is larger to demarcate the calibration difficulty, when material level blanking in the storehouse or vibrations reason generation height inclined-plane, controller can only calculate material level by logical formula according to the one side that is in contact with it, metering demonstration amount often can with actual amount deviation to some extent, and maintaining difficulty comparatively, life cycle is short; Only use a Pulverized Coal Bin, when coal mill or dynamic powder concentrator break down when needing to shut down, in the process of overhaul of the equipments, original Pulverized Coal Bin coal dust exhausts, and follow-up equipment just needs to shut down; And when fluctuation appearred in the coal dust of Pulverized Coal Bin, the quality of coal dust was unstable; Raw material directly enter rotary kiln after by preheater in the Cement clinker buring process, and the rate of decomposition of Wingdale is lower in this moment raw material, give that calcining has increased burden in the kiln, and the calcining coal consumption is larger in the kiln, and clinker is on the low side, and quality fluctuation is larger.
