Description

Full factory torch pipe-line system

Technical field

The utility model relates to a kind of torch pipe-line system, particularly relates to a kind of full factory processing pipe network torch pipe-line system.

Background technique

Full factory processing pipe network torch pipe-line system is the safety system that guarantees the oil refinery emergency decompression, and it is the inflammable gas pipeline that each oil refining apparatus discharge of safety valve or emergency episode are discharged, and the trouble-free operation of this pipe-line system is the safe and reliable guarantee of plant area.Because this pipeline laying circuit is longer, bore is bigger, and does not allow arbitrarily to arrange the emptying condensate drain, also will guarantee respectively to install the low back pressure of safety valve simultaneously, so this pipeline is difficult point and key point in plant area's safety system design.

This shows that above-mentioned existing full factory torch pipe-line system obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.

Summary of the invention

The purpose of this utility model is that a kind of full factory torch pipe-line system is being provided, and it can guarantee ground safety and operations stably such as oil refinery.

The purpose of this utility model and to solve its technical problem be to adopt following technological scheme to realize.The utility model is a kind of full factory torch pipe-line system, comprises main pipe and a plurality of lateral, wherein, this full factory torch pipe-line system pipe support top layer that is laid in separately, and be designed to " π " curved; This full factory torch pipe-line system is segment design, and is provided with a plurality of minutes flow containers in different positions; 45 ° of this laterals along the medium directions from top to bottom or 45 ° of substantially horizontals insert main pipes; This lateral inserts the access point place of main pipe, adopts the high strength pipe clamp.

By technique scheme, the full factory of the utility model torch pipe-line system has following advantage and beneficial effect at least: the utility model can guarantee ground safety and operations stably such as oil refinery, reduces cost of investment simultaneously, increases the benefit.

Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, and for above-mentioned and other purposes, feature and advantage of the present utility model can be become apparent, below especially exemplified by preferred embodiment, and conjunction with figs., be described in detail as follows.

Embodiment

Be to reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, to according to a kind of full factory its embodiment of torch pipe-line system, structure, feature and the effect thereof that the utility model proposes, describe in detail as after.

A kind of full factory torch pipe-line system that the utility model provides comprises main pipe 1 and a plurality of lateral 2.

Consult illustrated in figures 1 and 2ly, this full factory torch pipe-line system is laid in separately, and (because full factory torch pipeline laying is longer, Fig. 1 and Fig. 2 only illustrate a part of torch pipeline to the pipe support top layer.), and be designed to " π " curved.Generally speaking, full factory torch pipeline laying is longer, plant area's scale of one 5,000,000 tons for example, general long about 2000 meters of torch pipeline.A bag shape must not appear in this torch pipeline, and must consider the thermal compensation of heat pipe when purging, from Fig. 1, Fig. 2 as can be seen, the torch pipeline is designed at top layer separately, and when being designed to " π " curved absorption heat expansion, can not collide with the electric crane span structure 12 of other process pipelines 10, common line 11 and instrument, also be that laying and the maintenance of cable, instrument line leaves the space simultaneously.In addition, this full factory torch pipe-line system be supported on capital, can reduce the use of structural beams, save investment effectively, increase structure stability.

This full factory torch pipe-line system be segment design and a plurality of minutes flow containers 3 are set, these minutes flow container 3 be arranged at different positions.Wherein, this full factory torch pipe-line system whole process bag shape must not occur and not establish condensate drain, then must be provided with gradient pipeline and the aspect torch divides flow container, and slope requirement is not less than 2 ‰, i.e. i 〉=2 ‰.Because full factory torch pipeline whole process is longer, so the plan-position of the full factory's layout of the utility model basis and each emission point, height etc., whole process is divided into the n section, see Fig. 3 (a part of torch pipeline only is shown), every section peak A with divide flow container 3 apart from about 400m, can control about 0.8 meter of the discrepancy in elevation of peak A and minimum point B like this, and peak A joins between each section, minimum point B in the aspect section arranges branch flow container 3 at minimum point B simultaneously.

Referring to Fig. 4, be the separatory schematic representation of of the present utility model minute flow container.In actual production, the low spot lime set enters branch flow container 3 by pipeline a, liquid level reaches one regularly in minute flow container 3, close pipeline a valve DN50, open valve DN50 and the DN20 of line b, c and d, nitrogen enters branch flow container 3 by line c, and the pipeline d of flared gases by the separatory tank top returns the torch house steward, the lime set of telling is by the airtight sump oil system that returns of line b, this scheme implementation is convenient, invest lowlyer, and safety is flexible, convenient full factory divides many phases to build simultaneously, and the design of torch line is unaffected each other.

Simultaneously, consult Fig. 5 and shown in Figure 6, be the be connected detail drawing of torch pipeline main pipe 1 with lateral 2; Wherein, this lateral 2 with 45 ° along the medium directions from top to bottom or the mode of 45 ° of substantially horizontals insert main pipe 1, this not only can reduce pressure drop, satisfy the back pressure requirement of respectively installing safety valve, can prevent simultaneously impact and prevent that torch airsetting liquid from blowing back into lateral and forming fluid-tight, and cause local resistance.

In actual applications, because mesohigh device or unit discharge of safety valve pressure reduction are very big, and discharge amount is bigger, so can cause very big impact force to main pipe when inserting main pipe, causes main pipe to come off from support beam easily, causes security incident.Simultaneously, the common way that Torch support is set can not satisfy safety requirement, so the utility model in these cases, insert the access point place of main pipe 1 at lateral 2, adopt high strength pipe clamp 4, namely be to be responsible for the support that adopts in the lateral access of mesohigh device or unit, to reach vertical support and to keep out the requirement of horizontal impact power.Generally speaking, for preventing main pipe landing from the civil engineering beam column 14, this high strength pipe clamp 4 is placed on the civil engineering beam column 14, referring to Fig. 7.The utility model does not limit concrete structure and the constituent element of this high strength pipe clamp, as long as achieve the above object, and according to load size decision pipe clamp periphery shaped steel size.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
