Description
Technical field
Be cleaned and dried technical field the present invention relates to gas cylinder, a kind of cleaning and drying method more particularly to composite cylinder and
Device.
Background technique
Vehicle CNG composite cylinder have light-weight, rigidity is good, intensity is high, toughness is high, anti-corrosion and when by impact failure not
It the advantages that risk fragment can be generated, is widely used.Gas cylinder belongs to one of special equipment of national regulation, needs according to national regulation
Exercise supervision inspection and periodic inspection.Vehicle CNG composite cylinder by long-term use after, gas cylinder internal inevitably results from
Pollutant, usually heavy hydrocarbon and sulfide, national Specification must be internally dry to gas cylinder progress, so, carrying out gas cylinder
Be cleaned and dried to gas cylinder before being cleaned and dried seems and is even more important.
CNG gas cylinder internal cleaning at present rinses gas cylinder internal frequently with the water flow of pressurization, and water takes away the dirt in bottle when flowing out
Contaminate object.The shortcomings that this mode, is:
1) time of longer flushing, low efficiency are usually required；
2) certain oil ingredients are not soluble in water in pollutant, and some is attached on inner wall and can not clean up completely；
3) a large amount of water are needed, water resource waste is caused；
4) waste water is difficult to be recycled after cleaning, and environmental pollution is serious.
Now, the shortcomings that domestic CNG gas cylinder mostly uses heated-air drying mode, this mode is:
1) hot-wind-drying time is long, and gas cylinder internal, which is completely dried, at least needs 1 hour；
2) temperature is more than 65 DEG C, is easy to damage composite layer.
Have in GB24162-2009 " compressed natural gas for automobile metal liner fiber-wound gas cylinder periodic inspection and evaluation "
Clear stipulaties: the gas cylinder through water pressure test qualification, it is necessary to it is internally dry by only carrying out, and inside is not to be exceeded 65 DEG C.When dry
Between answer long enough to guarantee to be completely dried in bottle.
A kind of efficient gas cylinder cleaning system (Authorization Notice No. CN 205386562U) of patent proposes a kind of efficient gas cylinder
Cleaning system has the disadvantage that
1, there is no temprature control unit, empirically property is passed directly into steam and carries out internal washing about 4 minutes, no temperature control system
System.According to current experimental conditions, half a minute steam will make gas cylinder temperature rise to 100 DEG C or more, already more than GB24162-
2009 regulation, so, the method that patent CN 205386562U is provided is cannot to be used to clean CNG composite cylinder；
2, it is purged and is cooled down using nitrogen, use cost and equipment cost are all very high；
3, some researches show that for high-efficiency washing and high efficiency drying gas cylinder, it is desirable that steam is different with the flow field of air, therefore
Different steam and air approach axis must be used.Patent CN 205386562U can not using same root pipeline access gas cylinder
Meet high-efficiency washing and drying gas cylinder simultaneously.
