Description
Technical field
Patent of the present invention relates to spherical filling body, is used to be filled in the volatile inflammable and explosive liquid/gas body container, reaches fire-retardant datonation-inhibition effect.
Background technology
Liquid such as petrol and diesel oil and liquefied gas fuel gas, and the explosion-proof problem of the storage of all kinds of hazardous chemicals, transportation facility and instrument use the security of the various vehicles of liquid fuel gas, are one of key subjects of the explosion-proof research in countries in the world always.
For the safety that ensures China's economic development and production is carried out, country has successively formulated and has put into effect a series of relevant regulations and measure to ensure the safety of people's life and property, and the while has also advanced the carrying out of keeping the safety in production effectively.Yet current situation of production is still severe, and rapid economy development makes every profession and trade still have various potential safety hazards, and great especially big casualty accident oil takes place, by the state leader is paid attention to safety supervision is machine-operated.
As chemicals production big country, the situation of China's hazardous chemical safety in production is also comparatively severe, and one of its key factor is that the essential safety degree of manufacture of materials and warehousing and transportation facilities is lower.Inflammable, the explosive liquid gaseous chemical product cask in fields such as traffic, the energy, chemical industry and the safe contradiction of device become increasingly conspicuous, and accident takes place frequently, and bring very big loss and harm for the country and people's lives and properties.
According to statistics in 2006, seat surplus the total gas station 90,000, the whole nation.Because national economy fast development and quickening of urbanization process; Cause the part gas station to produce many serious potential safety hazards, not up to standard such as safe distance and safety measure, ageing equipment or the like; In case run into external factor, blast and fire possibly take place at any time.
There are nearly 400,000 oil gas transport vehicles in China at present, in case run into the burst factor, these transport vehicles just possibly become 400,000 time bombs.Product oil is in transportation, and because of static, traffic accident accident, and the total number of accident that the improper maintenance of equipment and container etc. causes accounts for 95 %.
In addition, the needs of national defense safety, the existence of factors leading to social instability and terrorist activity has both at home and abroad all proposed requirement to the safety anti-explosive problem.Adopt high-tech means, the essential safety problem that fundamentally solves inflammable and explosive product is imperative!
To the main cause that blast produces, every profession and trade adopts the passive-type defensive measure mostly at present: like electrostatic defending, and lightning protection; Fire-proof motor electrical equipment, the protective ground connecting to neutral, the lubricated elimination of machine rubbed; Adopt the instrument (copper instrument) that does not produce spark, No Open Flames, anti-Exposure to Sunlight etc.
The main cause that the blast of container storage tank produces:
1) container inner pressure that causes of temperature overheating or burning is too high;
2) electric energy is converted into ignition source: electric spark, electric arc, static discharge, short circuit, thunderbolt, electromagnetic radiation;
3) mechanical energy is converted into ignition source: friction, bump, adiabatic compression etc.;
4) measure of restriction fire spread comprises: like fireproof door, and fire retardant device, explosion-proof relief device etc.
But the explosion-proof defective of passive-type is to be difficult to really fundamentally to remove a hidden danger and reduce the loss that burst accident brings.
Since nearly half a century, explosion-proof technology is because of its importance in every profession and trade, and the continuous expansion of using, and receives the generally attention of national governments always, and dropped into great amount of manpower in succession and material resources are researched and developed.
Many governments, testing agency and independent experiment chamber have all played an active part in the test event of various explosion-proof lamps; Many explosion protection systems are tested through the key of association area; Being proved has explosion-proof function to inflammable and explosive liquid air-capacitor utensil; So explosion protection system is selected for use the fuel tank of protecting the various vehicles by army and other governments.
The technology that reaches datonation-inhibition purpose through filling explosion-proof lamp in flammable and explosive substance belongs to the essential safety method, is the most safe and reliable explosion-proof method, is applicable to the most dangerous occasion.The essential safety technology is the developing direction of explosion-proof technology.
But, because the limitation of current various explosion-proof technologies does not have the real overall application of a kind of product ability so far in industry-by-industry.
Several kinds of representative explosion-proof technologies of following brief account:
One, inert gas explosion-protection equipment
From eighties of last century nineties; Have only 3 jet airliners altogether because spark initiation fuel tank and blasting; The most heavy is on July 17th, 1996, U.S. Trans-World Airlines 800 flights were blasted after the lift-off of JFK airport, New York soon, caused on the machine 230 people all wrecked.Federal Aviation Administration proposed to set up relevant regulations in 2005, took place once more to prevent the fuel tank explosion incident.The planemaker is with too high this proposal of refusal of serving as reasons of cost.
Minister Mary Peter Si of Department of Transportation announces the aviation safety new regulation on July 16th, 08, requires the jet airliner of some models and cargo aircraft that a kind of device that prevents the fuel tank blast must be installed.Associated Press 16 days report, new regulation are applicable to that fuel tank such as Boeing-747 passenger plane is positioned at the new product passenger plane and the cargo aircraft of waist.New regulation says that planemaker and civil aviation company must install a kind of device aboard, and this device can replace very easily explosion caused oxygen with inertia nitrogen and fill fuel tank when fuel oil uses up.
Two, polyurethane (PU) foam
As far back as twentieth century sixties, a kind of polyurethane foam with explosion-proof effect obtains the confirmation of authoritative institution in the U.S. and Britain.This material property is more stable, has substituted the inertia system that is applied to oil tank at that time very soon.
But; The experience of USAF in Southeast Asia has appeared this material and has been applied in the weakness in the fuel tanker; The tropical climate of local high humiture exposes this material shortage hydrolytic stability (moisture-resistant degree property is poor), only causes the service life in 2 to 5 years fault to be given birth to frequently, and fuel system is contaminated.Filter gets clogged.What deserves to be mentioned is that this material is so far still in the offshore racing boat, use in fields such as Formula One cars and part aircraft, because this is unique system that can reduce the high temperature risk of explosion before fire-retardant explosive technology.
Three, metal intercepts explosion-proof technology
Intercepting explosion-proof technology and come from the beginning of the seventies, that the Canadian R&D team that is led by its Hungary inventor Joseph has carried out continuing is nearly four/centurial working hard to complete.
Intercepting explosion-proof principle is that container is divided between cellular zone, and utilizes heat-conduction effect to eliminate the blast area (demolition point) in the reservoir vessel, makes it lose explosion condition, thereby effectively prevents the generation of explosion accident.
Get into the nineties, intercept the explosion-proof net grid material that explosion-proof technology derives a kind of structure of metal foil, have significant explosion-proof effect.China is more late than external starting to the research of block blast-proof materials, and the block blast-proof materials of researching and producing mainly is the metal species block blast-proof materials.
Though metal current class block blast-proof materials obtains to use comparatively widely at home, still there are problems in this kind explosion-proof lamp:
1) metal forming explosion-proof lamp volume is bigger; Be generally the honeycombed structure of curl shape or stratiform; Filling in oil tank, dismounting, clean and maintenance process are loaded down with trivial details, and operation is difficulty very, usually need be to reequiping in the existing Fuel Tanking Unit; Installation, dismounting and cleaning cost are higher, and internal structure comparatively complicated apparatus is difficult to install especially;
2) for solving above-mentioned installation question, metal foil material derives a kind of spherical product, can be through the tubular inlet container of packing into, but, in the filling process, can produce jam because of the mutual hook of bead, and block the filling pipeline, also be difficult for filling simultaneously container.
3) this material can produce metal fragment with inner wall of oil tank and self friction wearing and tearing in the vehicle moving process, not only oil product is used deleterious impact, and blocks the problem of polluting oil line pipe and filtration system.
4) this material in use can compress, be out of shape through the rocking for a long time of oil plant, impact; Subside until overall structure; Thereby cause the container top not packing space to occur; Very easily blast at this gas mixture that gathers, have bigger potential safety hazard, be difficult to obtain popularizing in an all-round way in industrial quarters especially military field.
5) this kind material also exposes in various degree oil pollution and oxidation in application; Oil property is had a negative impact; The for example long-term acidity and the actual limb matter of back oil product used can increase, and 16 fearful values of hot a heatable brick bed value, induction period and the diesel oil of gasoline can descend etc. to some extent.
Just because of the existence of above-mentioned shortcoming, limited of further application and the development of metal species block blast-proof materials in China, make it be difficult to obtain popularizing in an all-round way in industrial quarters especially military field.Particularly military fuel aspect does not still have desirable block blast-proof materials to come into operation at present, therefore needs badly to conduct a research to be applicable to the novel block blast-proof materials of my the military fuel of army.
Known public technology is that (its applying date is on October 16th, 2007 to application number 200780050216.7 disclosed a kind of spherical filling bodies at present; Open day is on November 18th, 2009; Priority date is respectively [32] 2006.11.21 [33] AT [31] A1916/2006, [32] 200612.4 [33] AT [31] A2007/2006, [32] 2007.7.3 [33] AT [31] A1023/2007), be the most approaching prior art of the present invention, it adopts fabricated structure; Promptly adopt a plurality of round sheet bodies to splice each other; Carry out preprocessing output semi-finished product sheet material in factory, the automation assembling is carried out at the scene of being transported to, and finally is processed as finished product.
Its advantage is that cost of transportation and field machining cost are lower.But shortcoming is also apparent in view: axially adopting a plurality of round sheet bodies, radially adopting the round sheet body with perforation, structural strength is lower.If use the quantity of round sheet body too much, then can increase manufacturing cost, and influence the flowability of liquid in container, and if the quantity of use round sheet body is very few, then can reduce the effect of flame-proof explosion-proof again greatly.So can only be applied to common field of explosion-proof security,, adopt the product of this technology manufacturing can not meet the demands for the higher occasion of explosion proof ratings.
