Description
[technical field]
The present invention relates to a kind of feeding device of flyash, be specifically related to a kind of feeding device of the flyash for Vertical Mill.
[background technology]
Known, flyash receives to catch the thin ash got off from the flue gas after coal combustion, it is the primary solids refuse that coal-burning power plant discharges, along with China's coal-burning power plant's power generation capacity with 7.3% annual growth sustainable growth, and then bring the sharply increase of flyash quantity discharged, wherein the quantity discharged of flyash in 2010 is about 300,000,000 tons, expects 2015 and will reach more than 600,000,000 ton.So the comprehensive utilization to flyash, and flyash is turned waste into wealth to become in China's economic construction an important techno-economic policy.At present, flyash mixes cement clinker as blended material and is in the industry cycle used widely, the base mateiral that simultaneously flyash also can be used as aluminum i ndustry is applied, and above-mentioned application all must with Vertical Mill by its grinding to certain fineness, dry powder coal ash reaches required fineness according to the existing partial material of rank difference, but the past is all entered to grind by same passage by dry, wet fly-ash and cement clinker or Wingdale, cause grinding and grinding efficiency low, be therefore necessary to study the grinding and the grading effect that adopt the flyash feeder of which kind of type could produce the best.
Existing flyash feeder, first, flyash and other material share 1 and enter to grind passage, and be arranged in powder separating machine lower case place or water body Vertical Mill cylindrical shell place, although do the drying effect that part improves material like this, but causing fly ash grain group also not have enough time to reach corresponding particle terminal velocity just falls on mill, causes the mill efficiency of grinding machine to reduce; In addition, the existence of a large amount of flyash, adds the dust content of air-flow and the circulating load of flyash in mill, causes the fractional efficiency of powder separating machine to reduce; And the increase of dust content directly has influence on the increase of the drag losses of cement vertical mill body, indirectly cause the increase of system fan power consumption, be unfavorable for the energy-saving and cost-reducing of process system product; Secondly, the normally common material of existing flyash feeder, will be worn out about causing pipeline half a year, for this problem, the modification measures of user increases wear-resistant sleeve porcelain coating at pipe interior, make the life-span of pipeline bring up to more than 2 years, but effect is still not ideal; 3rd, when adding wet flyash in flyash feeder, often there is putty phenomenon, having had a strong impact on the ingredient stability of cement and the operation factor of flyash feeder.Unreasonable factor in all these designs above-mentioned, all makes the running that flyash feeder can not be long-time, efficient and stable, and then causes grinding and select the efficiency of powder to reduce.
