Description
Technical field
The utility model relates to mechanical, reclaims breather pipe for a kind of oil gas is provided, and particularly a kind of petrol service station oil gas reclaims the terminal vacuum pressure valve filter of breather pipe.
Background technology
Its dependence to oil of country of industry high level of development is a lot; Petrol service station is that the most important oil of customer provides window; At present the existing inside the province petrol service station of TaiWan, China has 2700 stations approximately, and the China's Mainland is more up to station surplus 100,000, because if volatile gasoline is when keeping normal open with outside air; Gasoline has 2 to 4 liters can loss evaporate in the air for per 1000 liters approximately, and not only waste increase operating cost more causes aerial contamination.Shown in accompanying drawing 1,, existing petrol service station oil gas implements illustration for reclaiming.According to the requirement of petrol service station oil gas recvery facility management method; Oil gas must reclaim, and existing equipment only is equipped with vacuum pressure valve at the breather pipe tail end, with the usefulness as adjusting oil groove pressure; The concern preservation of oil gas of this valve; The good corrupt rules and regulations that only rely on of function are every two years made periodic inspection one time by the professional, can only not had the special petrol service station oil gas recovery breather pipe vacuum pressure valve front end that is directed against and installed additional a filter for installation again by the autonomous management of station side beyond the phase journey and examine surely; When can cause vacuum pressure valve to block inefficacy because of scrap, unknown.The above keeps mainly puzzlement on the normal function keyholed back plate for petrol service station to aerial contamination.In addition because of the vacuum pressure valve device specifies in more than 4 meters, when some station is close to private residence, can be installed on the roof, the normal aloft work that needs is changed in maintenance, cause maintenance and when installing the worker pacify puzzlement.When it uses in reality; It is terminal that main device reclaims breather pipe in petrol service station oil gas; Mounting filtering device before the vacuum pressure valve; Petrol service station oil gas reclaims the terminal vacuum pressure valve filter 2 of breather pipe, starts into oil gas 15 and outside air normal open in the petrol service station oil resevoir 11 because of scrap is stuck to avoid vacuum pressure valve 12, not only to aerial contamination, let oil gas loss drain evaporation waste and more violate present environmental regulation; Especially when truck tanker 10 emptyings; 15 moments of gasoline pour into fast and very easily cause gas to dash in the oil resevoir 11 and the foreign material such as iron rust oxidation scrap in the pipeline are rushed at oily mat through breather pipe 14 by going into oil pipe 16, reclaim the terminal vacuum pressure valve filter 2 of breather pipe by the butt joint sleeve pipe 13 petrol service station oil gas that is spirally connected, and are stuck and cause many drawbacks to avoid vacuum pressure valve 12.
There is following drawback in prior art from the above:
1. can't let oil gas reclaim the gas omission and survey more stablely, vacuum pressure valve often irregularly has dirt or paralyses because of the iron filings in the breather pipe, and then causes leakage; Frequency is a lot of, and for causing the nonconformity and the uneasy maximum factor, the vacuum pressure valve leakage rate is quite high; When long-pending dirty the inefficacy is difficult to prevision; Be the management and control blind spot, cause and expend management and the raising of equipment replacement cost, and not environmental protection and impracticable again.
2. each environmental administration checks down to each petrol service station oil gas recvery facility function, if be imposed punishment against rule, it is excellent be determined, but is an individual no small pressure secret worry to the petrol service station owner.
3. the high salinity in seashore; Often cause the corrosion of iron pipe wall; Even there are stone or white fine sand (claiming the galvanized pipe bits again: possibly be chemical molecular and the interior galvanizing coating derivant of pipe in the gasoline) to gather in it; A pile iron filings situation is gathered in the vacuum pressure valve cleaning of taking off, and for leaking main cause, causes equipment replacement and maintenance cost to improve.
The utility model content
The purpose of the utility model is to provide a kind of petrol service station oil gas to reclaim the terminal vacuum pressure valve filter of breather pipe; Solve vacuum pressure valve and cause because of scrap is stuck that oil gas communicates with outside air in the petrol service station oil resevoir; Not only to aerial contamination, let the oil gas loss waste of running off, and violate the problem of present environmental regulation.
The utility model principal character is to add filter at the front end that oil gas reclaims the terminal vacuum pressure valve of breather pipe; Be prone to cause gas to dash during earlier with RTC unloading and the foreign material such as iron rust oxidation scrap in the pipeline are added filter; Petrol service station oil gas reclaims the terminal vacuum pressure valve filter of breather pipe; To avoid the terminal vacuum pressure valve of being installed stuck and cause many drawbacks, it is mainly constructed: a fixing baffler between last sleeve pipe and case in, the high filter screen of device closeness above this baffler; Below then mat fixed sleeving spiral shell knot one is penetrated with the breather pipe of several air extractor vents, and ties a collection bits groove in this breather pipe below spiral shell and form.
Wherein go up the device that sleeve pipe, baffler, case in can be one;
Wherein the density of filter screen can be unrestricted according to the actual needs conversion;
Wherein the hole count of air extractor vent can be unrestricted according to the actual needs conversion;
Wherein the distribution density of air extractor vent can be unrestricted according to the actual needs conversion;
Wherein the pore size of air extractor vent can be unrestricted according to the actual needs conversion;
Wherein air extractor vent can be circular port, tri-angle-holed, polygonal hole;
Wherein the collection bits groove depth depth can be unrestricted according to the actual needs conversion;
Wherein the filter screen degree of depth depth can be unrestricted according to the actual needs conversion;
Wherein go up sleeve pipe, case in length length can be unrestricted according to the actual needs conversion.
The advantage of the utility model is:
One, can reduce the vacuum pressure valve leakage rate greatly regularly with amassing dirty cleaning, break through the management and control blind spot, can reduce oil and gas leakage.
Two, can reduce because of piping engineering and leave over foreign matters such as stone in muffler, breather pipe, cement bonded sand, branch, iron filings, unload under the circulation impact pressure of receiving operation, cause the vacuum pressure valve body to block and cause and leak thing and take place at truck tanker.
Three, can reduce the galvanized steel tube wall corroded iron bits of breather pipe, or white fine sand (claim the galvanized pipe bits again: be the gasoline chemical molecular with pipe in the galvanizing coating derivant) gather in it, avoid leaking because of this thing causes the vacuum pressure valve body.
Four, can relax truck tanker and unload the receipts oil plant cycle pressure impact impaired probability that valve body caused, have safe and practical property.
Five, can reduce leakage, reduce oil gas loss volatilization relatively, but additional income reduces aerial contamination and receives the pressure of empty dirty penalty note, i.e. economy environmental protection again.
Six, the manoevreability that employing activity easy-off array mode, dismounting are considered maintenance clearly to be worth doing is high, has the reduction maintenance cost, substitutes simple and easy and the difficult damage of vacuum pressure valve, and reaches the practicality that saves time, economizes ability, environmental protection.
