Description

Technical Field

[0001] The utility model relates to an arrangement structure of pipelines on a pipe gallery, in particular to an arrangement structure of a flare gas pipeline and a steam pipeline on the pipe gallery. Background Art

[0002] On the pipe gallery of petrochemical equipment, flare gas pipelines and steam pipelines generally adopt natural compensation. Natural compensation of pipelines means that the pipeline uses the flexibility of this natural bending shape to compensate for its own thermal expansion and end displacement. The characteristics of natural compensation are simple structure, safe and reliable operation, and low investment. According to the design temperature of the flare gas pipeline, the flare gas pipeline is generally set with a flat π-shaped bend because low points are not allowed on the pipe gallery; and the steam pipeline is generally set with an upward π-shaped bend.

[0003] In the pipeline gallery of petrochemical plants, the general design is to lay the flat π-shaped bends of the flare gas pipeline independently on one layer (the flat π-shaped bends affect the straight laying of ordinary pipelines on the same layer of the pipeline gallery); at the same time, the general design is to lay the upward π-shaped bends of the steam pipeline independently on another layer of the pipeline gallery, so that part of the space in the pipeline gallery on the layer of the flare gas pipeline is idle. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a layout structure of flare gas pipelines and steam pipelines on the pipeline gallery which can fully utilize the space of the pipeline gallery and realize natural compensation and has simple structure, safe and reliable operation and low investment.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a layout structure of a flare gas pipeline and a steam pipeline on a pipe gallery, the flare gas pipeline is provided with a flat π-shaped bend, the steam pipeline is provided with an upward π-shaped bend, the flare gas pipeline and the steam pipeline are laid on the same layer of the pipe gallery, the flare gas pipeline is laid on one side close to the pipe gallery column, the steam pipeline is laid on the other side close to the pipe gallery column, the flat π-shaped bend and the upward π-shaped bend are arranged at the same position on the pipe gallery, and the upward π-shaped bend overlaps with the flat π-shaped bend up and down.

[0006] Furthermore, the ratio of the arm length to the arm width of the flat π-shaped bend is 2: 1. Under this ratio, the natural compensation effect is most ideal.

[0007] Furthermore, the arm width of the upward π-shaped bend is greater than the arm width of the flat π-shaped bend, so that the upward π-shaped bend completely covers the flat π-shaped bend in the length direction of the pipe gallery.

[0008] Furthermore, the ratio of the arm length to the arm width of the upward π-shaped bend is 2:1.

[0009] Compared with the prior art, the utility model has the following advantages: the utility model provides a layout structure of the flare gas pipeline and the steam pipeline on the pipeline gallery, which "nests" the flat π-shaped bend of the flare gas pipeline and the upward π-shaped bend of the steam pipeline on the pipeline gallery of the petrochemical device together to save space, that is, the flare gas pipeline and the steam pipeline are laid on the same layer of the pipeline gallery, the flare gas pipeline is laid close to the pipeline gallery column on one side, and the steam pipeline is laid close to the pipeline gallery column on the other side; while the flat π-shaped bend of the flare gas pipeline is set at a certain position in the pipeline gallery, the upward π-shaped bend of the steam pipeline is also set at this position, and the protruding parts of the two pipelines overlap up and down. The flare gas pipeline and steam pipeline designed in this way can not only make full use of the space of the pipeline gallery, but also realize the advantages of simple structure, safe and reliable operation and low investment of natural compensation.
