Description
One, technical field: the utility model relates to liquefaction automobile with compressed natural gas aerating technical field, especially skid-mounted type liquefaction automobile with compressed natural gas 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 not having a natural gas source area automobile with compressed natural gas becomes and needs the matter of utmost importance that solves.At present external existing liquefaction automobile with compressed natural gas 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 the city of no gas distributing system and automobile with compressed natural gas market-ripe, the aerating that is not suitable for the city automobile with compressed natural gas market development in early stage and can't builds central area, the big city automobile with compressed natural gas of fixed station owing to restricted by factors such as safety, land used to automobile with compressed natural gas.
Three, summary of the invention: the purpose of this utility model is to overcome the prior art above shortcomings, a kind of skid-mounted type liquefaction automobile with compressed natural gas aerator is provided, the utility model purpose is achieved in that mainly by liquefied natural gas (LNG) tank, last implementation of port, following implementation of port, safety valve, atmospheric valve, explosion-proof apparatus, the boost pressure regulation valve, the pressure of storage tank table, storage tank liquid-level meter, blwr, quick action emergency valve, the liquefied natural gas high pressure pump, the liquefied natural gas high-pressure carburetor, the compression natural gas expansion tank, the compression natural gas gas selling machine, check valve, expansion tank, compression indicator, excess flow valve is formed by connecting, and 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, and 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, excess flow valve are installed on the instrument airduct line of quick action emergency valve successively; Liquefied natural gas high pressure pump, liquefied natural gas high-pressure carburetor are installed on the liquid phase pipeline successively; The liquefied natural gas high pressure pump has pipeline to be communicated with the gas phase of liquefied natural gas (LNG) tank; Compression natural gas expansion tank, compression natural gas gas selling machine are installed on the aerating pipeline successively; The liquefied natural gas high pressure pump is the low temperature plunger pump, and the liquefied natural gas high-pressure carburetor is an air temperature type vaporizer; The instrument wind of control system is the normal temperature gaseous natural gas through heating in the liquefied natural gas (LNG) tank, and whole device is installed on the sled piece.
When skid-mounted type liquefaction automobile with compressed natural gas 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 automobile with compressed natural gas aerating, the aerating flexible pipe of compression natural gas gas selling machine is linked to each other with the automobile-used steel cylinder of automobile with compressed natural gas, start liquefied natural gas pump, liquefied natural gas in the storage tank enters the liquefied natural gas high-pressure carburetor after boosting through the liquefied natural gas high pressure pump, in the liquefied natural gas high-pressure carburetor, be vaporizated into compression natural gas, enter the compression natural gas expansion tank then, compressed natural fuels gas selling machine metering back adds in the automobile-used steel cylinder of automobile with compressed natural gas.
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 automobile with compressed natural gas market development in early stage, the Development of Compressed Natural Gas Vehicles city aerating that interim aerating point is set or can't builds central area, the big city automobile with compressed natural gas of fixed station owing to restricted by factors such as safety, land used.
