Description
The application is 200910038146.4 for application number, and the applying date is on March 24th, 2009, and denomination of invention is divided an application for " Supply Method and the device of a kind of portable liquid natural gas and gas phase rock gas ".
Technical field
The present invention relates to the technical field of liquid natural gas and gas phase natural gas supply.
Background technique
Rock gas (NG) is to come out the back also through gained after the necessary purified treatment from underground mining.Liquid natural gas (LNG) be by NG through further purifying, remove impurity and deep cooling to approximately after-162 ℃, make it to become a kind of material of liquid condition, be a kind of clear energy sources.NG and LNG can be used as the alternative energy source of fuel-engined vehicle as motor car engine fuel, and obviously, NG and the LNG after gasification can use for all types of user by pipeline, have remarkable economical and environment-friendly advantage.
In recent years, along with the fast development of LNG Liquefied natural gas industry, the LNGV (liquefied natural gas vehicle) industry had obtained significant progress in the world.At present, the whole world has more than 10000 LNG automobile moving.The country that use amount is maximum is the U.S., Canada, Japan and Russian, and the U.S. has 4000 LNG automobiles approximately, more than 60 LNG Vehicle Fueling Station.
China's LNG automobile industry is started in the beginning of this century.Beijing took the lead in developing the demonstration fleet that has 50 LNG bus in 2002, auxiliary construction domestic first seat coach LNG gas station---the LNG gas station in the Bai Miao bus terminus of Beijing.Thereafter in September, 2004,20 the LNG buses in Urumqi City, Xinjiang put into operation.In December, 2005,50 the LNG buses in Changsha, Hunan and 1 LNG filling station formally put into operation.Then self-dependent technical force of Guiyang City, Guizhou Province public transport company reequips the diesel oil bus, has had at present more than 600 of the LNG bus of repacking, and building simultaneously has 1 LNG filling station.
No matter be abroad or domestic, the LNG automotive industry all also is in an elementary developing period, and scale generally is not too big.Therefore, give LNG filling station quantity that the LNG automobile provides supply of fuel, layout etc., be difficult to adapt to the demand of LNG development of automobile inevitably.The filling website is few, it is that the ubiquitous problem of LNG automobile is promoted in various places that filling is inconvenient to, even the thing that the LNG automobile casts anchor because of running out of gas halfway also happens occasionally, and all makes troubles for LNG automobile operator and user, seriously restricts the development of LNG automobile industry.
And the construction of filling station is a challenge that relates to multiple factors such as planning, expropriation of land, declaration, design, construction, safety technique, operation management, can not solve the few and irrational problem of layout of filling website the short time, each area all is like this quickly.
So, how under filling site few (short time is difficult to solve), the irrational again current conditions of layout, adopt which kind of economical rationality mode and effective way? by which kind of technology and facility? the LNG automobile that better solution is cast anchor midway " emergent filling ", perhaps " the convenient filling " of partial L NG automobile, perhaps the problems such as " special services " of LNG automobile under the special status is all types of user " next to the shin " service is provided.
Simultaneously, expand, expand the purposes of filling apparatus as possible, realize the multiple function of a set of equipment, improve cost performance.Such as, (LNG bottle group user class is similar to LPG bottle group user for LNG bottle group fills liquid phase LNG.Be that a plurality of LNG bottles are joined together, concentrate the gasification back) to commercial user or residential quarters pipe network user air feed; Perhaps with after the LNG gasification that stores in the filling apparatus, be used for the emergent air feed of some areas gas distributing system, source of the gas replenishes peak regulation, local pipe networks ftercompction or the like." liquid phase filling ", " liquid phase fills " and " gas phase supply " are provided, and these several respects are technical problems to be solved by this invention.
Existing LNG automobile filling station as shown in Figure 1.Conventional LNG automobile dosing method mainly is to rely on to build at the fixed L NG in a certain location filling station.Typical LNG filling station process flow diagram is illustrated in fig. 1 shown below.
LNG filling station working principle is as follows:
The LNG filling station mainly is made up of from supercharging vaporizer 102, tank car pressurized machine 103, LNG liquid filler 106 etc. LNG storage tank 101, LNG immersed pump 105, storage tank, and the LNG vehicle alternative fuel can be provided.
Unload: LNG Liquefied natural gas tank car 104 is transported to the LNG filling station with LNG, utilizes the LNG gas phase supercharging of 103 pairs of tank cars 104 of tank car pressurized machine, LNG (liquid phase) is unloaded to the interior LNG low-temperature storage tank 101 in station store.
Filling: the LNG liquid in the storage tank 101 enters 106 meterings of LNG liquid filler after immersed pump 105 pressurizations, and by the vehicle-mounted bottle filling LNG of filling gun realization to LNG vehicle 107, the cryogenic gaseous rock gas is carried back LNG storage tank 101 by muffler in the vehicle-mounted bottle again.
Storage tank is from supercharging: when the LNG gaseous pressure is on the low side in the storage tank 101, improve storage tank self pressure by means of storage tank from supercharging vaporizer 102.
The pressure pipe net used for the user during the LNG gas that need diffuse was concentrated and entered.Filling station for no pipe network arrives adopts usually and installs the form that BOG reclaims compressor additional, will charge into the air cylinder group after the BOG gas pressurized and reclaims.

1. regulate the saturation state of medium in the storage tank 201.Promptly when the vehicle motor that with LNG is fuel needs the LNG of specific saturation state, can adjust the saturation state parameter of LNG in the storage tank by this equipment;
2. during running on the lower load, the LNG that is used for gasifying uses during for pressure pipe network users low-load, need not open immersed pump, to save the power consumption of pump;
3. the supercharging vaporizer of unloading that can be used as the LNG tank car uses.Promptly when LNG transport vehicle 215 is not joined from the supercharging vaporizer, utilize this equipment to realize that supercharging is unloaded to tank car.
5) the submerged combustion vaporizer 203: adopt the forced gasification mode, by burning gas phase LNG supplied heat source, be used for case of emergency under or the occasion of other needs LNG that gasifies fast uses for regional pipe network user, reach quick, the purpose of amount of vaporization greatly.Select Japanese imported product for use, vaporization ability 5000m
3/ h (gas phase), 35 ℃ of vaporizer hot water temperatures, 5-10 ℃ of gas phase gas outlet temperature, smog discharge temperature is 40 ℃, plant bulk is little, gas pressure after the gasification is adjustable in 0.05～0.4MPa scope, and self gas consumption is 1.2%, is delivered to pipe network after the natural gas via pressure regulation metering after the gasification.
6) pressure regulation and measuring apparatus 204: adopt self-powering type pressure governor and ultrasonic flowmeter, realize pressure regulation and metering to gas phase LNG, scope can be pressed.
7) safe bleeding device: when the LNG storage tank causes pressure constantly to be elevated to exceeding storage tank safety valve setting force value because of evaporation, the Safety relief valve of configuration will be opened the emptying pressure release automatically.
Apparatus of the present invention process flow diagram is illustrated in fig. 2 shown below.
