Description
Technical field
The present invention relates to storage or the transport field of oil product, especially relate to and adopt film every storaging and transport technology to solve the storage tank storing or transport by problems such as energy-saving and environmental protection in oily process, safety, quality.
Background technology
At present, oil product is in the transhipment of rail tank car and automobile oil truck, storage and use, oil product (such as gasoline, solvent naphtha, coal tar naphtha, aviation kerosene, light diesel and crude oil etc.) the ubiquity Big and Small Breath effect that volatility is higher, thus cause oil product evaporating loss, mix with air after oil evaporation and produce oil gas.As shown in Figure 1, for oil gas in prior art oil tank produces the schematic diagram of principle.Tank body 1 ' is for accumulating oil product 3 ', and oil product 3 ' enters in tank body 1 ' from oil inlet 6 ', then discharges from oil outlet pipe 7 '.When charge of oil, oil product 3 ' enters from oil inlet 6 ', and along with the rising of pasta, the gas in tank body is discharged from breathing pipe 10 '; When emptying, oil product 3 ' is discharged from oil outlet pipe 7 ', and along with the reduction of pasta, extraneous air enters in tank body 1 ' from breathing pipe 10 '.The process of above-mentioned charge of oil and emptying completes once large breathing.When oil product 3 ' is in tank body 1 ', owing to being subject to temperature, atmospheric pressure change, and the reason such as concussion in transportation, little breathing can be there is by breathing pipe 10 ' in the gas in tank body and outside air.Because oil product 3 ' in tank body and air directly contact, therefore, the oil vapour that oil product 3 ' evaporation is formed and air are blended in the cavity of tank body and form oil gas 2 ', and oil gas 2 ', along with Big and Small Breath, is discharged in external environment.
Oil vapour pollution environment, has carcinogenesis, under Ultraviolet radiation can and other pernicious gas generation photochemical reaction in air, form the larger secondary pollution of toxicity, aggravate the harm of people and damage the ozone layer.Oil gas turn increases the danger of presence of fire and blast, and fire and explosion accident have larger destructiveness to ecology environment.Oxygen simultaneously in air and oil product catalytic oxidation generate colloid will affect oil quality; Light ends evaporation in oil product also will affect oil quality.Therefore, every year in the storage and transport process of oil product, the evaporation loss of oil product is very large, more increases the pollution to environment, creates very large potential safety hazard.
Although part truck tanker and oil storage have employed Investigation of Petroleum Vapor Recovery Technology and reclaim, recovery method investment is comparatively large, reclaims not exclusively, and tank body needs good leak tightness, the pressure that bears higher, is the technology of administering again after a kind of pollution.The operation of erecting equipment from China Taiwan and continent, fault rate is high, operation and maintenance cost is high, does not have economy, and the concentration of oil gas is in Explosive Range, in transit having high risk, most oil gas, eventually through burning process, still has certain pollution.
