1．设备的主要参数 General Description of the Reactors 聚丙烯装置的第一环管反应器 R7201 及第二环管反应器 R7202 的设备总重 量均为 344t（包括钢结构及连接梁的重量） ，主要由 R1、R2、R3、R4 四个带夹 套的直管段，其中 R1 与 R2、R3 与 R4 各有上部的一个半园管、一个连接直管 组成。在每个直管段之间有 7 层连接横梁。在直管段 R1、R2、R3、R4 的下段 处，分别装有环管反应器的四个支座，这些支座的安放位置是在反应器框架距地 面有 6 米高的平台上。反应器的整体高度为 50121mm，四个带夹套的直管段中心 距为 4200mm×4200mm。 the first loop reactor R7201 and the second loop reactor R7202 for polypropylene unit have a total weight of 344t (including the weight of steel structure members and connecting beams ), which mainly consist of 4 legs R1, R2, R3 and R4 with jacket. There is a semicircle elbow and a connecting straight pipe on the upper ends of R1 and R2, R3 and R4 respectively. There are 7 connecting crossbeams between two legs from down to top. The 4 legs R1, R2, R3 and R4 are provided with 4 bearing stands at lower part respectively, which are to be placed on a 6m high platform on the concrete frame for the reactor. The total height of the reactors is 50,121mm and the center line of the 4 legs with jacket is 4200mm× 4200mm. 2．吊装方案的选择 Selection of Lifting Scheme 根据现场的条件及现有的吊装机具，环管反应器 R7201 及 R7202 的吊装，采 用单台吊车提升、分两片吊装的方法来安装，主吊车选用一台 250t 履带吊（美 国的 Manitowoc M-250 型） ，另外还需用一台 250 履带吊（美国的 Manitowoc Model-999 型）辅助溜尾。 According to the site conditions and the riggings available, loop reactors R7201 and R7202 will be lifted by a single crane in two pieces. A crawler crane of 250t (Manitowoc M-250 made in U.S.A) will be used as the main crane and a crawler crane of 250t (Manitowoc Model-999 made in U.S.A) will be used for tailing. 3．吊装的平面布置 Lifting Layout
