Description

TECHNICAL FIELD

[0001] The utility model relates to a spring support for limiting vertical and horizontal displacement of steam pipeline, which is used in the technical field of compressed air energy storage. BACKGROUND

[0002] As a large-scale long-time energy storage technology, non-reheat compressed air energy storage has realized engineering demonstration of different capacity levels in China. This technology uses electric energy to drive an air compressor to compress ambient air, obtain high-temperature and high-pressure compressed air, and then uses a heat carrier to absorb most of the heat energy and store it after heat exchange. After the air is cooled and released, it enters the gas storage device, thereby storing electric energy in the form of a heat carrier and compressed air. When releasing energy, the stored compressed air exchanges heat with the stored heat carrier, absorbs heat, and enters the air expander to reduce pressure and do work, driving the generator to rotate and generate electricity, while the heat carrier is stored after being cooled, thereby realizing the regeneration of electric energy.

[0003] In the compressed air energy storage technology, the pipe diameter connected by the air compressor and the expander is relatively large, and the temperature after compression is relatively high. Both the compressor and the expander device interface allow the pipe thrust and torque to be relatively small. In actual engineering, due to limited pipe layout space, adjusting the device interface stress is often a difficulty in pipe thermal analysis and calculation. During thermal analysis, the device interface torque is greatly affected by pipe displacement, and a limiting device needs to be installed at an appropriate position. In many cases, the horizontal X direction (perpendicular to the pipe axial direction) and Y direction (along the pipe axial direction) torque is too large, which is often caused by excessive pipe vertical displacement. In this case, the pipe vertical displacement needs to be analyzed and limited at an appropriate position (limited by the civil structure). When calculating, the vertical displacement is limited to zero, and the torque is still large but the torque direction changes. Through analysis, the support at the position where the pipe is hot and the support at the cold state have a certain displacement in the Z direction (vertical direction). At the same time, the horizontal X direction displacement cannot be too large, otherwise it will cause excessive Z direction torque. Therefore, a limiting device for the steam pipeline is needed to meet the above conditions. SUMMARY

[0004] The utility model discloses a spring support for limiting vertical and horizontal displacement of steam pipeline, which can limit in the vertical Z direction and the horizontal X direction, and can also meet the support in the vertical Z direction when the pipeline is hot and cold, and limit in the horizontal X direction, without causing excessive Z direction torque.

[0010] Further improvement of the technical scheme of the utility model lies in that a peep hole is formed on the shell wall for conveniently checking the compression spring inside, and a peep hole is also formed on the corresponding position of the support pipe.

[0011] Further improvement of the technical scheme of the utility model lies in that the mounting base of the support spring and the support pipe are fixed on the embedded part in the civil support pier, and the fixing mode is welding.

Figure 2As shown, the support spring 3 comprises a shell fixed by the mounting base 3-8, the shell wall 3-6 and the top shell cover 3-4, and a load-bearing cylinder 3-2 extending out of the shell and being telescopic by the elastic force of the compression spring 3-5.
