同时核对装填数量与高度是否相符,核对装填的规格型号是否和合成塔内的要求相符,并记录后再依次进行下一段的装填。认真做好装填记录,装填完毕,催化剂密度应大于或等于设计值的99%。3、上部惰性球装填方法催化剂装填结束后,用木板抹平表面,按要求装填上部耐高温惰性氧化铝球,,装好后,抹平表面,装丝网盖板,上盖密封,并用氮气保压,以防催化剂吸潮或被有毒气体污染。催化剂装填时注意事项为了防止在装填过程中,催化剂过多的吸收空气中的水分,装填催化剂时应选择晴朗、干爽的天气,不要在阴、雨天装填;催化剂不要长时间暴露在空气中,特别是潮湿的地方更需引起注意。

净化工程集中式真空吸尘法:集中式真空吸尘是一个由吸尘口、管网、集中吸尘泵、除尘器组成的系统。吸尘泵和除尘器设在专门的机房内,因噪声极大,机房不但要远离厂房和办公区,而且还要适当地作隔声消声处理。吸尘泵应有备用不应少于2台。系统的管道宜用无缝钢管焊接联接暗装敷设。其弯头曲率半径为4~6d煨弯不得折皱,三通夹角要小于45,不应有四通(可由2个三通组合),水平管道的坡度为3,坡向立管和吸尘点,拐弯处宜设清扫口。
