【摘要】 吉林省桦甸市、农安县油页岩资源丰富。以桦甸市示范电厂油页岩渣为主要原料,用新的烧胀试验方法开展了超轻陶粒的研制,采用自制的新试验装置,烧制出的陶粒接近实际陶粒回转窑水平,并可专门烧制小颗粒陶砂,可比现有烧胀试验方法工作效率提高约50倍;并以国产陶粒设备,提出拟建年产20万m3陶粒工厂工艺方案设计,对窑炉两端的余热利用提出了可行方案。油页岩渣SiO2,Al2O3,R2O含量适中,特别是含碳非常少,可以人为地调整发泡剂的用量而控制陶粒的密度,使在1 030~1 100℃范围内烧制出300~500 kg/m3级陶粒或陶砂。更多还原

【Abstract】 The resources of oil shale is extremely rich in Huadian city and Nongan county,Jilin（Province.） The authors preliminarily introduced a new technique to produce ultra light ceramisite with the oil shale dregs as main raw material in Shifan Electricity Plant with a new experimental equipment developed by ourselves.This equipment can produce normal ceramisite with the similar quality as the products of the rotary kiln.In addition,small ceramic slag can be produced.The working efficiency is promoted by several dozens times than existing burn-expand experiment method but the labor intensity significantly decreases.A ceramisite factory crafts with annual productivity of 200 000 cubic meters using domestic ceramisite production equipment were designed here.The surplus heat of the rotary kiln two extremities were reused in a feasible way.The content of SiO₂,Al₂O₃,R₂O in oil shale are moderate and the content of C is very low.The ceramisite density can be controlled by adjusting the quantity of the froth agent.Ceramisite & ceramic slag range with density from 300 kg/m³ to 500 kg/m³ can be produced at the temperature ranging from 1 030℃ to 1 100℃.更多还原
