Description
Technical field
The utility model is related to the fields LNG more particularly to a kind of atmospheric storage tank feed liquor pipeline systems.
Background technology
Currently, at LNG peak regulations station, deposit station etc. in other yards, the feed liquor of atmospheric storage tank be divided into individually upper feed liquor, under
Reflux pipeline after feed liquor and pump.
LNG peak regulations station, deposit station are different from liquefaction plant, and liquid source is mostly tank car or Shipping, and passes through pipeline of unloading
It is delivered to storage in storage tank, and when storage tank feed liquor, generally worked without drain, when this can lead to storage tank into liquid status, after pump
Reflux pipeline is idle after filling pipeline and pump；When storage tank drain state, the feed liquor pipeline of storage tank is idle；This two kinds of situations are to pipeline
When being that a kind of waste, especially pipeline are idle, internal remaining LNG can constantly gasify, and to generate a large amount of BOG, make
At a large amount of operating cost.It needs to optimize improvement to original feed liquor pipeline thus, while meeting normal use,
Equipment investment is reduced, operating cost is reduced.
Utility model content
It is idle that technical problem to be solved in the utility model is that tank line is easy, and when pipeline is idle, internal
Remaining LNG can constantly gasify, and it is an object of the present invention to provide a kind of normal pressure the problem of to generate a large amount of BOG, improve operating cost
Storage tank feed liquor pipeline system, solves the above problems.
The utility model is achieved through the following technical solutions：
A kind of atmospheric storage tank feed liquor pipeline system, including storage tank ontology, after being provided with lower feed liquor pipeline, pump on storage tank ontology
Reflux pipeline and storage tank are pre-chilled pipeline, and storage tank ontology is connected with pump, and reflux pipeline and storage tank are pre-chilled after the lower feed liquor pipeline, pump
Pipeline is connected to pump, and is provided with two-way pipe between reflux pipeline after pump and pump, and is connected with the external world by two-way pipe.
When storage tank is into liquid status, reflux pipeline is used for the daily feed liquor of storage tank after lower feed liquor pipeline and pump, can be by LNG safety
Ground is delivered to tank inside storage；When storage tank drain state, reflux pipeline can be used as the reflux pipeline of Loading Pump after pump, can will pump
Part LNG is back to tank inside afterwards；Feed liquor of the pipeline for work to be pre-chilled before storage tank for the first time feed liquor is pre-chilled in storage tank.
The utility model is improved the optimization design that the feed liquor pipeline of atmospheric storage tank carries out, by inlet tube line on storage tank and
Reflux pipeline merges after pump, and reflux pipeline undertakes the function of flowing back after feed liquor and pump after making original pump, when reduction pipeline is idle
A large amount of BOG gases that LNG gasification generates, and eliminate original upper inlet tube line, are not separately provided from area of unloading to storage tank
The feed liquor pipeline of ontology, greatly reduces cost.
Further, the outlet of the lower feed liquor pipeline is located at below the storage tank ontology.
Further, the outlet of reflux pipeline is located above the storage tank ontology after the pump.
Further, the outlet of the lower feed liquor pipeline and storage tank precooling pipeline is both provided with internal spraying ring pipe.
The utility model compared with prior art, has the following advantages and advantages：
1, a kind of atmospheric storage tank feed liquor pipeline system of the utility model closes reflux pipeline after inlet tube line on storage tank and pump
And reflux pipeline undertakes the function of flowing back after feed liquor and pump after making original pump, LNG gasification generates big when reduction pipeline is idle
Measure BOG gases；
2, a kind of atmospheric storage tank feed liquor pipeline system of the utility model, after reflux pipeline undertakes feed liquor and pump after original pump
The function of reflux eliminates original upper inlet tube line, is not separately provided from feed liquor pipeline of the area to storage tank ontology of unloading, significantly
Reduce cost.
