Description
Affiliated technical field
The present invention relates to the device of a kind of low pressure, normal pressure storing and transporting oil products, belong to the storage transportation technology field of oil.
Background technology
At present, oil product comprises links such as ducting, rail tank car and automobile oil truck transportation, oil tanker transportation, oil depot storage tank stores, petrol service station storage, the storage of equipment fuel tank in transhipment, storage with in using.Oil depot storage tank (upright tank) stores because of adopting floating top technology to reduce the breather loss more than 90%, but because floating top technology is difficult to be applied to horizontal tank, the breather loss that the horizontal tank ubiquity is bigger, cause oil product evaporating loss, quality to descend and environmental pollution, have fire and explosion safety hidden danger.
Be that example is set forth below with gasoline.
According to safety and environmental protection office of China PetroChemical Corporation " finished oil merchandising business gasoline exhaust of oil control criterion " explanation of compilation, gasoline stores the link loss at horizontal tanks such as rail tank car and automobile oil truck transportation, petrol service stations and is about 1%, the annual gasoline that consumes of China is more than 5,000 ten thousand tons, the year loss is above 500,000 tons, about 5000 yuan/ton of gas price is lost about 2,500,000,000 yuan.This does not also comprise the loss of equipment (automobile) fuel tank.
The oil vapour contaminated environment, petrol service station is many, and a oil vapour can pollute the air of 2000 times of volumes at surrounding city, 5,000 ten thousand tons of gasoline general oil vapour that forms 5 times of gasoline volumes to I haven't seen you for ages in the transportation and sale process, volume is about 3.4 hundred million sides, and foul air just reaches 6,800 hundred million sides.Oil vapour under ultraviolet irradiation can with other pernicious gas generation photochemical reaction in the air, form the bigger secondary pollution of toxicity, aggravation is to people's harm and damage the ozone layer.Oil vapour has increased the danger of presence of fire and blast again.Fire and explosion accident have bigger destructiveness to ecology environment.
Airborne water vapour is breathed with size and is entered storage tank, forms condensate water behind the drop in temperature in storage tank, influences the quality of oil product; Airborne oxygen contacts with oil product and will influence oil quality simultaneously; Light ends evaporation in the oil product also will influence oil quality.
The higher oil product of volatility also has solvent naphtha, coal tar naphtha, aviation kerosene, light diesel and former wet goods except that gasoline, and therefore annual evaporation loss will be more, and environmental pollution is bigger.
Even part groove (jar) car, petrol service station and oil storage have adopted technology such as absorption, condensation, absorption or membrance separation to reclaim, all need increase investment and consume energy (money) source but reclaim, and reclaim not exclusively.Every the price in oil depot reclaiming scrap reaches 500～1,500 ten thousand yuan; From China Taiwan and the continent operation of erecting equipment, fault rate height, operation and maintenance cost height do not have economy at 30～1,000,000 yuan yet in every of petrol service station reclaiming scrap, and most oil vapours are finally handled by burning; And the oil vapour that is mixed with air is in transit being had high risk.Therefore administer from the source that oil vapour produces and be only the basic road of dealing with problems, can receive the effect of getting twice the result with half the effort.
Summary of the invention
In order to overcome problems such as the breather loss of device in accumulating oil product process such as having oil depot storage tank, railway and road tank vehicle, petrol service station storage tank, equipment fuel tank now and the environmental protection that brings thus, safety, quality, the invention provides a kind of film isolation type oil storage and transportation apparatus.
The present invention includes housing 1, oil inlet 6, oil outlet pipe 7 and pneumostome 10, be provided with film 2 in the housing 1 greater than its volume, film canned paragraph 4 places of housing 1 top installing port 3 are fixed at the top of film 2, the remainder of film 2 and housing 1 are in released state, the internal layer of film 2 is communicated with pneumostome 10, and film 2 is isolated the inner chamber and the air of housing 1; Oil inlet 6, oil outlet pipe 7 are located at the top or the bottom of housing 1, be communicated with the inner chamber of housing 1, oil inlet 6, oil outlet pipe 7 are equipped with valve 9 and quick coupling 8, the top of housing 1 is provided with safety valve 11, oil inlet 6 and safety valve 11 are positioned on the cover plate 5 of case top, and cover plate has the porose anti-blocking screen casing 16 of cloth on the wall for 5 times; Pneumostome 10 is located at the top of housing 1.See Fig. 1.
By contacting of liquid storage product and air in the film 2 isolation storage tanks, the remainder of film 2 rises and falls with respiration.
Evaporation is fluid molecule leaving away from liquid level on the microcosmic.Fluid molecule is collision mutually in random motion, makes some molecules obtain big kinetic energy, if when these molecular kinetic energies overcome the required merit of intermolecular attraction in the liquid when flying out liquid level, just can break away from liquid level and become steam.
Adopt flexible film to be covered in liquid surface, blocked fluid molecule escape approach, isolate oil and air by film, respiration occurs in outside the film, avoids oil vapour to enter air, economizes on resources thereby reach; The protection environment; Improve storing and transporting security, reduce the danger of presence of fire and blast; Avoid oxidation and water to sneak into the quality of influence oil; Its flexible structure more helps external force such as opposing bump.
After transportation tank car, petrol service station oil tank and automotive oil tank adopt the present invention, can realize hermetic type accumulating (usefulness) oil, avoid oil and air directly to breathe, eliminate oil vapour pollution, improve safety.
The three elements that oil depot fire takes place are: oil vapour, air, kindling material when film covers the oil meter face fully, with contacting of isolated oil and air, reduce disaster hidden-trouble, raising tank car, petrol storage tank and the safety of equipment fuel tank.
Adopt flexible membrane to cover the oil meter face, respiration is finished in film, has avoided oil vapour and air directly to breathe.The invention has the beneficial effects as follows:
1. avoid oil vapour and air directly to breathe, the protection environment;
2. improve oil station transhipment environment, the health of protection operating personal;
3. avoid breather loss, energy savings;
4. cut off oil product and air, improve safety;
5. avoid the loss of easy evaporated fraction, guarantee the quality of oil;
6. cut off oil product and contact, avoid because of the oxidation affects oil quality with air;
7. avoid airborne condensate water and rainwater to enter and influence oil quality;
8. select the strong film of anti-stick ability, can effectively reduce sediment and adhere to, be beneficial to cleaning;
9. select the good film of antiseptic property, reduce maintenance work, reduce the maintenance risk;
10. reduce oil gas and reclaim transformation and bottom loading investment for trnasforming urban land.
The present invention can be used for vertical petrol storage tank transformation, horizontal petrol storage tank, equipment fuel tank and transformation, and is simple to the transformation of present petrol storage tank; Its enforcement can be eliminated present most oil vapour and pollute, and avoids the heavy dish accident in floating top of floating roof tank.
