Description

Technical field

[0001] The utility model relates to the field of reactors, in particular to an installation structure of an inner coil pipe and an outer coil pipe. [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. Among them, coils are important components in reactors. The stability of their structure and the efficiency of their installation are particularly important.

[0003] See also Figure 1 , which discloses a conventional installation structure for inner and outer coils, comprising: a plurality of vertical supports 1' arranged in a cylinder, the inner coil 2' being mounted on the inner side of the vertical supports 1' via a plurality of fixing members 3', and the outer coil 4' being mounted on the outer side of the vertical supports 1' via a plurality of fixing members 3', see Figure 2 The fixing members 3' were originally flat-plate-shaped and were laterally inserted into the vertical bracket 1' and welded to the vertical bracket 1'. When the coil and the vertical bracket were installed, workers bent the free ends of the fixing members to hook the coil to complete the installation. The defects of the installation structure of the inner and outer coils in the prior art are: 1. No tolerance adjustment mechanism is provided between the vertical bracket and the cylinder, thereby increasing the difficulty of manufacturing the equipment; 2. The fixing members of the prior art structure of this type are easily broken at the welding point between them and the vertical bracket when bent; 3. The coil fixing structure in the prior art cannot be disassembled after installation. Therefore, 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 to repair 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 separate fixing piece, and each circle of the outer coil also needs to be fixed with a separate fixing piece, which greatly reduces the installation efficiency of the entire coil.

In other embodiments, the number of vertical supports 4 can be determined based on specific needs. The inner coil 2 is arranged on the inner side of several vertical supports 4, and the outer coil 3 is arranged on the outer side of several vertical supports 4. The inner coil 2 is wound with several inner coil circles 20 along the vertical spiral, and the outer coil 3 is wound with several outer coil circles 30 along the vertical spiral. Every two adjacent inner coil circles 20 and every two adjacent outer coil circles 30 are fixed to the vertical support 4 through a coil fixing assembly 5. The coil fixing assembly 5 includes: a stud 50, a first nut 51, a second nut 52, an outer coil clamp 53, an inner coil clamp 54 and a first support plate 55 and a second support plate 56 welded to the vertical support 4.
