Description
Technical field
The present invention relates to construction technology, more particularly to a kind of down town lpg spherical tank method for dismounting.
Background technology
Remove the spherical tank of storage liquefied petroleum gas, it is necessary to line replacement and cleaning first are entered to spherical tank and affiliated facility, its mesh
Be that will remain and the constantly liquefied petroleum gas thorough cleaning that escapes is clean, reach as defined in could implement to tear open after safety condition
Remove.
At present various regions safety and environmental protection department accreditation replacement in spherical tank mode be：Torch burning system+sewage disposal system
Tupe.This method is after exhausting the extraction raffinate in spherical tank, residual air, and the residual air that can not be extracted out is discharged into the combustion of torch burning system
Burn, the residual gas that can not be burnt is interrupted unlatching by atmospheric valve and is discharged into air, uncaps after soaking 48 hours, raffinate is discharged into oil refining
Factory's sewage disposal system is further handled, and this method substantially has certain influence to surrounding enviroment and air.
But last century eight, the liquefied petroleum-gas station of the nineties construction do not possess torch burning system substantially, more not
Put forward sewage disposal system.In urban renewal, these large-scale liquefied petroleum gas storage and distribution station soils are no timely after being imposed
Remove, can bring about potential safety hazard over time, therefore be often referred to as " city stealth bomb ".
These are opened for the last time in the recent period using the liquefied petroleum-gas station generally existing of time for a long time without gas station as-constructed drawing, nothing
Tank situation inspection record, extraction raffinate, residual air quantity fail to understand that top tank structure extent of corrosion is unclear in tank, gas station equipment state, lightning protection earthing
The problems such as whether intact system, safety alarm device be not clear, it directly affects the security evaluation of displacement early stage.It is clear to reach displacement
Wash journey zero-emission, the requirement of no pollution is nearly impossible thing.
The content of the invention
Based on this, it is necessary to for problem present in background technology, there is provided one kind can no pollution, zero-emission tear open safely
The down town lpg spherical tank method for dismounting removed.
A kind of down town lpg spherical tank method for dismounting, comprises the following steps：
Carry out preparation of construction, it is ensured that the safe and smooth progress of follow-up work；
Extract the liquefied petroleum gas in spherical tank and its subsidiary pipeline out outward transport；
The liquefied petroleum gas that can not be extracted out in spherical tank and its subsidiary pipeline enters line replacement with water and cleaned, caused gas in replacement process
Body leads to burner combustion, and the liquid after the completion of displacement extracts outward transport out；
Steam is passed through in the spherical tank and its subsidiary pipeline cleaned up to displacement and is purged boiling repeatedly, is purged in digestion process
Caused gas leads to burner combustion, and the liquid after purging boiling is complete extracts outward transport out, until caused by purging digestion process
Gas can not burn, and purge boiling it is complete after liquid sampling assay it is qualified；
Spherical tank after complete to purging boiling carries out residue cleaning, until detection acceptance(check)；
The spherical tank for detecting acceptance(check) and its subsidiary pipeline are removed.
In one of the embodiments, the preparation of construction includes technique preparation, Farm Planning, personnel's preparation, work equipment
Prepare and measure prepares.
In one of the embodiments, the liquefied petroleum gas by spherical tank and its subsidiary pipeline extracts the step of outward transport out
Specially：The liquefied petroleum gas in spherical tank and its subsidiary pipeline is extracted out outward transport, until the pressure in spherical tank and its subsidiary pipeline
In below 0.05MPa.
In one of the embodiments, the liquefied petroleum gas that can not be extracted out in the spherical tank and its subsidiary pipeline is carried out with water
The step of displacement is cleaned, and caused gas leads to burner combustion in replacement process, and the liquid after replacing extracts outward transport out is specific
For：The water filling into the subsidiary pipeline of spherical tank, subsidiary pipeline is entered line replacement cleaning, displacement cleaning after be discharged into spherical tank with water after take out
Go out outward transport；
The water filling into spherical tank, to liquid level peak after suspend water filling, caused gas in the injecting process is led into burner combustion,
Continue interruption after having burnt and be filled to water spill-over to go out, stop water filling, after immersion 1 ~ 2 day, extract outward transport out.
In one of the embodiments, steam progress is passed through in the spherical tank and its subsidiary pipeline cleaned up to displacement
Repeatedly purge boiling the step of be specially：Steam is passed through into the subsidiary pipeline of spherical tank and is purged boiling repeatedly, purges boiling
Liquid is all flowed into spherical tank afterwards；
Steam is passed through into spherical tank and is purged boiling repeatedly, temperature control purges boiling each time below 60 DEG C in spherical tank
Time is more than 24 hours.
In one of the embodiments, described the step of removing the spherical tank for detecting acceptance(check) and its subsidiary pipeline, is specific
For：
The subsidiary pipeline of spherical tank is removed；
Multiple hangers are set respectively on top crown, upper temperature zone plate, equatorial plate, lower temperate zone plate and bottom crown in spherical tank；
