Description

[Technical field]

[0001] The invention relates to the field of reactors, and in particular to an installation structure of an inner coil and an outer coil. [Background technology]

[0002] Reactors are equipment that realize the reaction process and are used in chemical, oil refining, metallurgy, light industry and other industrial sectors. Reactors are composed of shells, coils and other components. Coils are important components in reactors, and their structural stability and installation efficiency are particularly important.

[0003] See also Figure 1 , which discloses an installation structure of an inner coil and an outer coil in the prior art, comprising: a plurality of vertical brackets 1' arranged in a cylinder, the inner coil 2' is installed on the inner side of the vertical bracket 1' through a plurality of fixing members 3', and the outer coil 4' is installed on the outer side of the vertical bracket 1' through a plurality of fixing members 3', please refer to Figure 2 The fixing parts 3' were originally arranged in a flat plate shape, which were horizontally inserted into the vertical bracket 1' and welded to the vertical bracket 1'. When the coil and the vertical bracket were installed, the workers bent the free end of the fixing parts to hook the coil to complete the installation. The defects of the installation structure of the inner coil and the outer coil in the prior art are: 1. There is no tolerance adjustment mechanism between the vertical bracket and the cylinder, which increases the difficulty of manufacturing the equipment; 2. The fixing parts of the structure in the prior art are easily broken at the welding point between the fixing parts and the vertical bracket when bent; 3. The coil fixing structure in the prior art cannot be disassembled after installation, so when the internal parts such as the heat exchange tube need to be repaired later, it cannot be repaired. Because the heat exchange tube is located on the inner side of the coil in the radial direction, the outer coil must be removed for repair of the heat exchange tube; 4. The inner coil and the outer coil are composed of several circles from top to bottom. In the prior art, each circle of the inner coil needs to be fixed with a fixing piece separately, and each circle of the outer coil also needs to be fixed with a fixing piece separately, which greatly reduces the installation efficiency of the entire coil.
