The invention relates to a heat exchanger replacement method, and relates to the technical field of sulfuric acid plant heat exchanger construction. According to the heat exchanger replacement method, the first replacement platform and the second replacement platform are installed beside the equipment foundation platform in advance, the new heat exchanger is installed on the first replacement platform in advance, the replacement and repair stop time of an old heat exchanger can not be occupied, the old heat exchanger operates normally in the installation period, and the production efficiency is guaranteed; meanwhile, the old heat exchanger and the new heat exchanger are moved and transferred through round steel in cooperation with the winch, replacement of the old heat exchanger and the new heat exchanger can be rapidly achieved, the replacement efficiency is improved, the production interruption time is shortened, and stable operation of sulfuric acid plant production is guaranteed. The first replacement platform and the second replacement platform which are installed in advance are small in occupied area, and large equipment replacement can be completed through a hoisting-free translation method under the condition that the site is limited and a large crane is not placed.
本申请是关于涉及换热器更换的方法,涉及硫酸厂换热器施工技术领域。本申请提供一种换热器更换的方法,通过在设备基础平台旁提前安装第一更换平台和第二更换平台,并在第一更换平台上提前安装新换热器,能够不占用旧换热器的更换修停时间,旧换热器在安装期间正常运行,保障生产效率;同时,本申请通过使用圆钢配合卷扬机移动转移旧换热器与新换热器的方式,能够快速实现旧换热器与新换热器的更换,提高更换效率,减少生产中断时间,以保障硫酸厂生产的稳定运行。本申请提前安装的第一更换平台和第二更换平台,其占用的面积较小,能够在场地受限不具备摆放大型吊车的条件下,用免吊装平移的方法完成大型设备更换。
