加氢裂化反应器这一类设备,由于用特殊钢种制造,所以设计中一般不在本体上设置吊耳,而是利用设备顶端的气相管口,作为单一的吊装受力点。该类反应器一般重量都在800～400t 以上,由于只有一个吊点用一般的施工方法吊装就位.具有一定的难度,上海石化总厂芳烃厂有一台国外引进的加氢裂化反应器,重量为520.7t,据外商专家介绍,他们使用的吊装方法是用1000t 和500t 特大型吊车各一台才能吊装就位,这种施工方法显然不适合我 Hydrocracking reactor This type of equipment, because of the use of special steel species, so the design is generally not on the body to install the lug, but the use of the equipment at the top of the gas phase nozzle, as a single lifting force point. The weight of these reactors is generally 800-400t or more. Since there is only one hoisting point lifted in place by ordinary construction methods, with certain difficulties, the aromatics plant of Shanghai Petrochemical Plant has a hydrocracking reactor introduced from abroad. 520.7t, according to foreign experts, the lifting method they used was to use one of the 1000t and 500t super cranes to lift them into place. This construction method is obviously not suitable for me.
