Description

[Technical field]

[0001] The invention relates to the field of reactors, and in particular to a coil installation structure. [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 a coil installation structure in the prior art, comprising: a plurality of vertical brackets 1' arranged in the cylinder, and a coil 2' is installed on the vertical brackets 1' through a plurality of fixing members 3', see Figure 2 The fixing piece 3' was originally set in a flat plate shape, which was horizontally inserted into the vertical bracket 1' and welded to the vertical bracket 1'. When the coil 2' and the vertical bracket 1' were installed, the worker bent the free end of the fixing piece 3' to hook the coil 2' to complete the installation. The defects of this coil installation structure in the prior art are: 1. No tolerance adjustment mechanism is set between the vertical bracket and the cylinder, which increases the difficulty of manufacturing the equipment; 2. The fixing piece of this structure in the prior art is easy to break the welding part between it and the vertical bracket when bending; 3. This coil fixing structure in the prior art cannot be disassembled after installation, so it cannot be repaired when the internal parts such as the heat exchange tube need to be repaired later, because the heat exchange tube is located on the inner side of the coil in the radial direction, and the outer coil must be removed for the repair of the heat exchange tube; 4. The coil is composed of several circles from top to bottom. In the prior art, each circle of the coil needs to be fixed with a fixing piece separately, so the installation efficiency of the coil is low.
