合肥固泰浅谈分格转子定量喂煤装置工艺系统和煤粉仓
来 源:www.gtzdh.com.cn     发布时间:2018-3-8 10:37:37

工艺系统:煤粉的特性是磨蚀性强,流动性中等;在含水较高的情况下容易形成棚料。在生产线上,一旦下煤不稳,势必影响分格转子定量喂煤装置的计量精度,同时对物料煅烧及工艺生产线的稳定性造成影响。因此,我们开发出适应计量物料特性的可靠的工艺系统,与高精度的计量装置组成一个完备的计量系统,以保证准确可靠的计量结果。

煤粉仓:设计煤粉仓时,要充分考虑煤粉防爆问题,还要防止煤粉在仓内起拱、结块等因素。煤粉仓的锥形部分垂直角度α应不小于70˚。在天气寒冷地区,煤粉仓需加保温层,以防止结露,保温方法如下:在煤粉仓四周,点焊Φ3-Φ4、长度为150mm、间距为200mm的铁丝,以便固定保温棉;

保温材料可以采用100mm石棉板,外侧用1mm镀锌板固定。煤粉仓的密封性必须良好,焊接处及接口部分不允许有泄漏现象,焊接完毕后用煤油采取内涂外查的办法检查有无泄漏。煤粉仓的容积必须在适当的范围内,一般为设备台时产量3~5倍,煤粉仓实际仓容最好不超过80%,仓顶接负压管,保持煤粉上部为负压,煤粉仓一般直径为4.5~5米,设计时必须考虑双层法兰结构,以防止仓体变形。



Process system: the characteristics of pulverized coal are strong abrasion and medium fluidity, and it is easy to form shed material in the case of high water cut. On the production line, once the coal is unstable, it will affect the metering accuracy of the quantitative feed device of the grid rotor, and at the same time, it will affect the stability of the material calcining and the production line. Therefore, we develop reliable process system that is suitable for measuring material characteristics, and constitute a complete measurement system with high-precision metering devices, so as to ensure accurate and reliable measurement results.

Pulverized coal bin: when the pulverized coal silo is designed, the problem of pulverized coal explosion-proof should be taken into full consideration, and the factors such as the arching and caking of the pulverized coal in the silo should also be prevented. The vertical angle of the conical part of the coal should be not less than 70 or alpha. In the cold weather area, the coal bunker should be added with insulation to prevent condensation. The following methods are as follows: in the vicinity of the coal bunker, we must weld the iron wire with the diameter of 3-, 4 and the length of 150mm, and the spacing is 200mm, so that the insulation cotton can be fixed.

100mm asbestos board can be used as insulation material, and 1mm galvanized sheet is fixed on the outside. The sealing property of the pulverized coal bin must be good. Leakage is not allowed at the welding and interface parts. After the welding is completed, kerosene should be taken inside the coating to check whether there is any leakage. The volume of coal must be in the proper range, general equipment yield 3~5 times, the actual storage capacity of coal warehouse top preferably not more than 80%, negative pressure tube, keep the upper coal pressure, coal general diameter of 4.5 ~ 5 meters, should be considered in the design of double flange structure, to prevent deformation of the silo body.
