The summarizing outside ice chest such as liquid nitrogen, liquid oxygen, liquid argon is also a subject under discussion needed to be considered, when air separation unit number is more than 3 sets, storage
Corresponding inlet can not possibly be arranged according to space division tricks in tank, cannot singly cover space division and be connected into respective inlet, need several sets
Into storage tank after first summarizing on piping lane.Consider when summarizing problem it is necessary to considering the maintenance of device, the draining of liquid, liquid oxygen pipe
The factors such as road safety, for liquid nitrogen and liquid argon pipeline, the safety factor being related to is less, passes through the arrangement of stop valve, conduit slope
And the reasonable setting of height can meet demand.But for liquid oxygen line, the spy in addition to considering Conventional cryogenic fluid pipeline
Property outside, it is accordingly required in particular to consider security risk caused by the hydrocarbon that causes because pipe arrangement is unreasonable is assembled.
Invention content
It is an object of the invention to overcome prior art Shortcomings, and provide it is a kind of by gradient setting, valve arrangement,
Valve heat insulation case design optimization pipeline rout reduces hydrocarbon aggregation, saves vacuum tube, saves piping lane space, avoid out
Existing oxygen pipe safety accident, more set space division liquid oxygen product pipelines of ensuring equipment safe and stable operation summarize device.
The purpose of the present invention is by following technical solution to complete, and a kind of pipelines of more set space division liquid oxygen products summarize
Device, including more single set space division liquid oxygen product pipes, more single set space division liquid oxygen product pipes pass through the manual shutoff that respectively connects
Valve is summarized by stainless steel pipes pipe fitting in low spot, and a stainless steel gathering tube, the stainless steel are connected after low spot summarizes
Gathering tube flows to liquid oxygen storage tank since aggregation point, along the gradient continued upward；The hand stop valve is cut as each branch
Disconnected valve, is placed in the opposite high point of pipeline, and by the equal centralized arrangement of hand stop valve in a valve heat insulation case.
As preferred：The valve preceding pipeline of the hand stop valve respectively by be built in valve heat insulation case stainless steel pipes and
The vacuum tube for being placed outside valve heat insulation case connects, and constitutes more single set space division liquid oxygen product pipes, the hand stop valve
Valve after pipeline by being built in each stainless steel pipes pipe fitting of valve heat insulation case and stainless steel gathering tube and being connected to stainless steel
Gathering tube and the vacuum connection tube composition for being placed outside valve heat insulation case；It is downward to connect 90 ° of elbows for pipeline after the valve, with other points
Branch summarizes in low spot, and low spot is provided with drain pipe.
As preferred：The heat preservation clack box is positioned over the list nearest away from liquid oxygen storage tank and covers near space division on piping lane；It is described
Height difference is set in the 250mm that can play the role of fluid-tight between the stainless steel gathering tube of pipeline after hand stop valve and valve；The hand
The valve preceding pipeline of dynamic shut-off valve according to piping lane in the upward gradient and is connected to single set by being picked out in ice chest, by the vacuum tube that connects
The stop valve of space division liquid oxygen product.
The present invention in device parking maintenance, by the drain pipe of fluid pipeline in ice chest arranged by stop valve preceding pipeline liquid
To the greatest extent, the liquid in manifold is drained by the drain pipe on low spot gathering tube, and the space division liquid oxygen product pipelines that cover can be avoided because converging more
The unreasonable safety accident for causing hydrocarbon to assemble and cause of total mode, has securely and reliably, rationally efficiently, can promote dress
The features such as setting safety and stability.
Description of the drawings
Fig. 1 is that more set space division liquid oxygen product pipeline of the present invention summarizes and moves towards schematic three dimensional views.
Fig. 2 is that more set space division liquid oxygen product pipelines of the present invention summarize clack box interior conduit correlation schematic diagram.
Fig. 3 is that more set space division liquid oxygen product pipelines of the present invention summarize the location drawing of the clack box in air separation unit total figure.
Specific implementation mode
Detailed introduction is done to the present invention below in conjunction with attached drawing：Fig. 1, shown in 2, a kind of pipes of more set space division liquid oxygen products
Summarize device in road, including more single set space division liquid oxygen product pipes, and more single set space division liquid oxygen product pipes pass through the hand that respectively connects
Dynamic shut-off valve 1 is summarized by stainless steel pipes pipe fitting 2 in low spot, and a stainless steel gathering tube 3 is connected after low spot summarizes, described
Stainless steel gathering tube 3 since aggregation point, flow to liquid oxygen storage tank 4 along the gradient that continues upward, as shown in Figure 3；It is described manual
Stop valve of the shut-off valve 1 as each branch, is placed in the opposite high point of pipeline, and by the 1 equal centralized arrangement of hand stop valve
In a valve heat insulation case 5.
As preferred embodiment：The valve preceding pipeline of hand stop valve 1 of the present invention is respectively by being built in valve heat insulation
The stainless steel pipes 6 of case 5 and the vacuum tube 7 for being placed outside valve heat insulation case 5 connect, and constitute more single set space division liquid oxygen productions
Quality control, pipeline is by being built in each stainless steel pipes pipe fitting 2 and stainless steel of valve heat insulation case 5 after the valve of the hand stop valve 1
Gathering tube 3 and be connected to stainless steel gathering tube 3 and be placed outside valve heat insulation case 5 vacuum connection tube 8 constitute；After the valve
Pipeline connects 90 ° of elbows 9 downwards, summarizes in low spot with other branches, and low spot is provided with drain pipe 10.
As further preferred embodiment：Heat preservation clack box 5 of the present invention is positioned over the list nearest away from liquid oxygen storage tank 4
It covers near space division on piping lane, as shown in Figure 3；Height difference is set between the stainless steel gathering tube 3 of pipeline after the hand stop valve 1 and valve
The 250mm of fluid-tight can be played the role of by being scheduled on；The valve preceding pipeline of the hand stop valve 1 is by heat preservation clack box 5（Ice chest）It inside picks out, leads to
The vacuum tube 7 to connect is crossed according to piping lane in the upward gradient and is connected to the stop valve 12 of single set space division liquid oxygen product 11.
The present invention by taking 6 sets of space divisions as an example, by piping lane three sets summarize, realize that two pipelines into storage tank, save true
The quantity of blank pipe, storage tank only need that two inlets are arranged, and simplify the piping near inlet, reduce the flat of storage tank inlet
Platform.By the setting of cut-out valve position, conduit slope, pipeline height to liquid oxygen line, avoid hydrocarbon in pipeline
In aggregation, to avoid safety accident.For the project implementation, reduce cost of investment and operation expense, promotes dress
Set safety and stability.
Embodiment：Shown in Fig. 1, each branch line of the present invention leads to pipe according to the upward gradient by singly covering space division
On corridor, it is located at pipeline high point as preferred manual stop valve, valve centralized arrangement is curved in heat preservation clack box, directly connecing 90 ° after valve
Head downwards, ensures that hydrocarbon is assembled not at valve, and height difference 250mm between gathering tube after valve and valve plays fluid-tight work
With.The drainage point of pipeline is located at the minimum point of gathering tube after valve, that is, summarizes the height of manifold extractions.
