Description
One, technical field: the utility model relates to a kind of LNGV aerating technical field, especially skid-mounted type LNGV aerator.
Two, background technology: liquefied natural gas is used on automobile as a kind of clean fuel, at present many do not have the area of natural gas source all to prepare to utilize liquefied natural gas to solve the pollution problem of vehicle exhaust to atmosphere, thereby the aerating of LNGV becomes the matter of utmost importance that needs solution.At present domestic and international existing LNGV gas station technological process complexity, take up an area of big, quantities is big, the cycle of building a station is long, investment is big, be applicable to of the aerating of ripe city, LNGV market, the aerating that is not suitable for the city LNGV market development in early stage and can't builds central area, the big city LNGV of fixed station owing to restricted by factors such as safety, land used to LNGV.
Three, summary of the invention: the purpose of this utility model is to overcome the prior art above shortcomings, and a kind of skid-mounted type LNGV aerator is provided.The purpose of this utility model is achieved in that mainly and is formed by connecting by liquefied natural gas (LNG) tank, last implementation of port, following implementation of port, safety valve, atmospheric valve, explosion-proof apparatus, boost pressure regulation valve, pressure of storage tank table, storage tank liquid-level meter, blwr, quick action emergency valve, liquefied natural gas pump, liquefied natural gas gas selling machine, check valve, expansion tank, compression indicator, excess flow valve.Liquefied natural gas (LNG) tank is the double-level-metal vacuum insulation vessel; Go up for outer jar explosion-proof apparatus is installed, on the interior jar of gas phase pipeline safety valve and atmospheric valve are installed; Be provided with on the liquefied natural gas (LNG) tank and going up implementation of port and following implementation of port; Pressure of storage tank table and storage tank liquid-level meter are installed in respectively on the impulse pipeline of liquefied natural gas (LNG) tank; The boost pressure regulation valve is installed on the gas phase pipeline of liquefied natural gas (LNG) tank; Blwr is connected on the liquid phase pipeline; Quick action emergency valve is installed in liquid phase and extracts out on the pipeline; Check valve, expansion tank, compression indicator and excess flow valve are installed on the instrument airduct line of quick action emergency valve successively; Liquefied natural gas pump is installed on the aerating pipeline; The liquefied natural gas gas selling machine is installed in the not end of aerating pipeline; Blwr is an air temperature type vaporizer; Liquefied natural gas pump, liquefied natural gas gas selling machine have pipeline to be communicated with the gas phase of liquefied natural gas (LNG) tank respectively; Liquefied natural gas pump is the low-temperature centrifugation pump; The instrument wind of control system is the normal temperature gaseous natural gas through heating in the liquefied natural gas (LNG) tank; Above all devices is installed on the sled piece.
When skid-mounted type LNGV aerator uses, the liquefied natural gas of uniform temperature, pressure is housed in liquefied natural gas (LNG) tank, filling by last implementation of port and following implementation of port of liquefied natural gas realizes.The pressure of storage tank is by boost pressure regulation valve automatic guidance: when the pressure of storage tank is lower than the setting pressure of boost pressure regulation valve, the boost pressure regulation valve is opened, and gives the storage tank supercharging by blwr, when pressure rises to the setting pressure of boost pressure regulation valve, the boost pressure regulation valve cuts out, and finishes supercharging.When giving the liquefaction natural gas vehicle refueling, the aerating flexible pipe of liquefied natural gas gas selling machine is linked to each other with the automobile-used storage tank of LNGV, start liquefied natural gas pump, liquefied natural gas in the storage tank enters the liquefied natural gas gas selling machine after boosting through liquefied natural gas pump, adds in the automobile-used storage tank of LNGV after the metering of liquefied natural gas gas selling machine.
This device is compared with similar products at home and abroad, have that technological process is simple, compact conformation, advantages such as occupation of land is little, quantities is little, the construction period is short, small investment, be applicable to the city LNGV market development in early stage, develop the aerating that the LNGV city is provided with interim aerating point or can't builds central area, the big city LNGV of fixed station owing to restricted by factors such as safety, land used.
Four, description of drawings: accompanying drawing is a skid-mounted type LNGV aerator structural representation:
