Description
Technical field
A kind of gas station's low pressure, normal pressure storage oil product technology are the utility model is related to, belongs to oil product storage technical field.
Background technology
At present, gas station is produced seepage in the individual layer tank used with sunken tankers by corrosion, and its seepage slowly is not easy to examine
Feel, it is lasting and serious to cause to pollute.Finished product oil seepage contains in addition to it can cause the major casualties such as fire or blast in oil product
Methyl tertiary butyl ether(MTBE) (the abbreviation of some mononuclear aromatics (abbreviation BTEX) and substitution lead tetraethide as addition for leadless gasoline
) etc. MTBE hazardous compound is with leaking into soil, and then polluted underground water source.Especially MTBE is highly soluble in water, can be with
BTEX compounds produce molten effect altogether, so as to aggravate the pollution of underground water；At present MTBE to the carcinogenicity of animal it is verified that,
Expiratory dyspnea, asthma, dizziness, headache, insomnia and the allergy such as eyes oedema and fash occurs in human body short-time contact MTBE
Property symptom.
In consideration of it, Political Bureau of the Central Committee in 2015 is by State Council's issue《Water prevention and cure of pollution action plan》It is required that
The antiseepage transformation of gas station will be completed before the end of the year 2017.
If existing individual layer tank, which is dug out, carries out antiseepage transformation, it is more than each direct investment 80~1,000,000 yuan of standing, the downtime
About 40 days, cause about 140~1,600,000 yuan of total losses.Rigid lining is applied, it is necessary to the time according to existing spraying or hand paste technology
About 16 days, costly, the downtime was more long, because of a large amount of solvent flashings of resin, inflammable and explosive and serious pollution in construction
Environment, at the same spray or brushing construction operation influenceed by temperature and humidity it is very big, solvent volatilization caused by micro- stomata can not keep away
Exempt from, transformation reliability is poor.Current rigid lining technology is difficult to use vacuum or pressure monitoring, does not reach antiseepage I levels.
If being transformed only with flexible liners technology, outer tank infiltration enters in tank, and water density is big compared with oil product, can influence the appearance of tank body
Product and the accuracy of metering, if repairing tank skin with resin, there is also some problems of above-mentioned rigid lining, therefore urgently have one kind
More reliable, convenient, fast, safe technology to carry out antiseepage transformation to gas station's storage tank, to protect soil and water resources.
Oil product can discharge oil gas when passing in and out oil tank simultaneously, inspiration air, cause air pollution, existing petroleum vapor recovery skill
Art does not have economic benefit, while handles power consumption and also result in pollution transfer, it would be highly desirable to which more advanced technology is effectively (cost-effective and environmentally friendly)
Administer.
Utility model content
In order to overcome existing gas station's storage tank antiseepage transform present in problem, the utility model provide a kind of repairing,
Strengthen the construction technology of original storage tank, structure is by compound resin (rigid lining F) and film (flexible liners L) in original storage tank
The combination of rigidity and flexibility lining of composition.By existing individual layer storage tank be changed to can leakage monitoring double-layer tank, reach I level antiseepages.Using film
