膨胀珍珠岩填充施工是LNG 储罐建设后期的关键工序之一,其填充质量直接关系到储罐投产后的保冷效果。珍珠岩现场膨胀、填充设备主要包括原料仓、膨胀炉、旋风分离器、热交换器、集尘器、输送系统、振实器等。膨胀珍珠岩的填充工艺流程包括填充之前的准备工作、膨胀珍珠岩的填充、填充效果的检测以及填充后的振捣。LNG 储罐珍珠岩的膨胀、填充作业是不间断作业,在整个作业过程中需采用振实密度检测仪、粒度分析仪等对珍珠岩的松散密度、振实密度、粒度级配、含水率及导热系数进行定时检测并记录检验数据,依据检测结果调整珍珠岩膨胀工况,可有效确保投产后LNG 储罐整体BOG 蒸发率测试合格,避免储罐珍珠岩保冷作用减小或失效。
As a key procedure of LNG storage tank construction at late stages, perlite expansion & filling may directly determine insulation performances of such tanks after they are put into service. Major perlite expansion and filling facilities on site include silos for raw materials, expansion oven, cyclone separator, heat exchanger, dust catcher, conveyer system and vibrator. Main procedures for filling of expanded perlite include preparation, filling, monitoring of effects and vibrating after filling. Since the perlite expansion and filling for LNG storage tanks are operations around the clock, densimeters and particle size analyzers should be mobilized to monitor loose density, compacted density, granularity grading, moisture content and thermal conductivity of perlite throughout the operations. All relevant data obtained in such procedures should be recorded properly. These data may serve as the basis for adjusting the expansion process of perlite. In this way, BOG evaporation of the LNG storage tanks can be ensured to eliminate possibility of poor performance or failure in insulation of perlite in storage tank.
