Description
Technical field
The utility model relates to compression natural gas gas station equipment, particularly a kind of vehicle-mounted aerator that is exclusively used in the microkinetic natural gas supply sub-station.
Background technology
2 classes are divided at the natural gas vehicle refueling station of widespread usage both at home and abroad at present: 1) take natural fuels by pipe-line transportation system (pipe network), the gas station of market goods locally after compression is called the standard station; 2) take natural fuels by pipeline, concentrate compression with many main equipments, the group of gas station who is transported to the strange land scattered distribution with high pressure vessel is called the mothers and sons system of standing.Concentrated compressor station claims female station, is that the gas station of source of the gas is the substation with vehicle-mounted pressure container.
Generally adopt the long tube formula transport trolley that meets the DOT standard at present both at home and abroad.The steel cylinder of 8 Φ 559 * 10975 and pipeline valve are formed forty foot equivalent unit, volume 8 * 2.25=18m3, operation pressure 20MPa.Container loading is called long tube formula transport trolley on standard superimposed trailer (chassis), rest against the substation source of the gas is provided.The whole parallel connections of its steel cylinder are one group, shared import and export, and the air pressure of every steel cylinder descends synchronously when the external air feed of transport trolley.
Because the volume of steel vessel is immutable, long tube formula transport trolley steel cylinder internal gas pressure behind the vehicle air feed of being bullied descends.For the vehicle storage pressure that guarantees to be bullied when transport trolley air pressure constantly descends reaches 20MPa, what generally adopt at present is station (fixing) gaholder group that is provided with in the substation by compressor tonifying Qi supercharging, its effect be vehicle-mounted container behind the gas cylinder air feed of the vehicle of being bullied once more to the vehicle air feed of being bullied, the air pressure of supplying the automobile gas cylinder is to 20MPa.The station of substation is made up of high-pressure gas cylinder and the middle pressure gaholder of maximum working pressure 25MPa with the gaholder group, press again high pressure to divide three methods to be called three-way order aerating mode in after this first low pressure, can improve gas cylinder gas taking rate and compressor operating efficient to the vehicle air feed of being bullied.
Get gas by long tube formula transport trolley, replenishing the equipment of standing with gaholder group air pressure is the substation compressor.The substation compressor is a specialized equipment, but automatic sequence is replenished bottle group pressure.Its equipment complexity, involve great expense.The efficient of compression energy is not high, consumption of power is bigger because the compressibility and the heat of compression of gas, mechanical energy are converted to, and this is the part that the substation investment is maximum, operating cost is the highest.
A kind of transport trolley (application number is 200420041973.1) patent application that is used for unpowered natural gas supply sub-station of applicant, it is the conveying arrangement that is used for unpowered natural gas supply sub-station, but need to use the steel cylinder of 25Mpa, bigger than the common transport trolley investment of 20Mpa steel cylinder.
Summary of the invention
The purpose of this utility model is to provide a kind of vehicle-mounted aerator that is exclusively used in the microkinetic natural gas supply sub-station.This device is by being divided into several groups of containers a hydraulic power group and several modes of the unpowered group air feed successively that divides into groups, and makes transport trolley possess the unpowered function that gas and hydraulic pressure unload gas of unloading simultaneously, in multi-thread mode to the gas selling machine air feed.Reach and not only utilize vehicle-mounted steel cylinder self pressure to unload gas, but also the effect of utilizing hydraulic power to supply to be bullied the container resulting pressure to need in a large number.
The utility model takes following technical scheme to finish, the vehicle-mounted aerator that is used for the microkinetic natural gas supply sub-station comprises that several are equipped with the groups of containers of compression natural gas, is characterized in that several groups of containers are divided into several unpowered group and a hydraulic power group.Each is unpowered group is formed and is connected into one group by converging gas row by 2-4 steel cylinder; The hydraulic power group is made up of 3-4 steel cylinder, and an end of each steel cylinder is equipped with for the interface that connects hydraulic hose, on the other end gas vent automatic controlling valve is installed, and organizes steel cylinder entirely and connects into one group by remittance gas row; The remittance gas of hydraulic power group row is communicated with unpowered group remittance gas row, and is provided with valve in its junction, before unloading the gas interface and inflating interface.
Different with unpowered natural gas supply sub-station transport trolley is that the utility model adopts the steel cylinder of operation pressure 20MPa, invests than the operation pressure 25MPa steel cylinder saving that unpowered substation special transport vehicle is selected for use.
