Abstract
The utility model relates to an energy-saving LNG packaging gas filling device which comprises an outer frame and a gas holder fixed inside the outer frame, an exhaust port is formed in the top of the gas holder and is connected with a gas collector through a guide pipe, and a gas exhaust device is arranged inside the guide pipe. According to the energy-saving LNG packaging gas filling device, as the exhaust port is connected with the gas collector, BOG gas needing to be exhausted is collected inside the gas collector, gas pollution to the environment is reduced, waste use is achieved, and cost is greatly lowered.
Description
Technical field
The utility model relates to LNG gas station aerating field, especially a kind of energy-saving LNG skid aerator.
Background technique
LNG is the abbreviation of LNG Liquefied natural gas, and it is that rock gas is dewatered, takes off hydrocarbon, desulfurization, removing CO
2After purified treatment, liquefaction is handled and is formed when low temperature, and main component is methane.Adopt LNG can reduce transportation and the carrying cost of rock gas greatly.Therefore, the LNG fuel automobile is one of main direction of following development of automobile.
LNG storage tank as one of main core component of LNG gas station, because the temperature of gas at each position in the storage tank not all is identical, along with the day-to-day operation of station system will inevitably allow pressure of storage tank raise, when reaching the pressure of storage tank safety margins, must discharge.In the prior art, common LNG storage tank all needs to discharge a certain amount of BOG gas (LNG gas and AIR MIXTURES) every day, the discharging of a large amount of BOG gas ground is the interior on-road efficiency in influence station and safety not only, also causes the wasting of resources and atmosphere is produced severe contamination, so need be improved.
The model utility content
The technical problems to be solved in the utility model is: for provide a kind of can exhaust gas utilization, reduce the energy-saving LNG skid aerator that pollutes, reduces cost.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of energy-saving LNG skid aerator, comprise external frame and be fixed on the interior gas holder of external frame, described gas holder top offers relief opening, described relief opening is connected with air collector by conduit, is provided with air extractor in the described conduit.
In preferred embodiment of the utility model, described conduit is provided with control valve.
In preferred embodiment of the utility model, described gas holder is fixed in the external frame by some mounting plates.
The beneficial effects of the utility model are: the energy-saving LNG skid of the utility model aerator is owing to be connected relief opening with air collector, the BOG gas that needs are discharged can be collected in the air collector, reduced the pollution of gas to environment, and can waste utilization, cost reduced widely.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the perspective view of a preferred embodiment of the energy-saving LNG skid of the utility model aerator;
Among the figure: 1. external frame, 2. gas holder, 3. relief opening, 4. air collector, 5. conduit, 6. mounting plate, 7. control valve.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of energy-saving LNG skid aerator comprises external frame 1 and is fixed on gas holder 2 in the external frame 1 that described gas holder 2 tops offer relief opening 3, described relief opening 3 is connected with air collector 4 by conduit 5, is provided with air extractor in the described conduit 5.
Described conduit 5 is provided with control valve 7, when needing discharging BOG gas, opens control valve 7, in the BOG gas suction air collector 4 that air extractor in the conduit 5 can be discharged relief opening 3, after having arranged BOG gas, closed control valve 7, the BOG gas in the air collector 4 can waste utilization.
Described gas holder 2 is fixed in the external frame 1 by some mounting plates 6, and sound construction is reliable, easy installation and removal.
Compared with prior art, the energy-saving LNG skid of the utility model aerator can be collected in the BOG gas that needs are discharged in the air collector 4 because relief opening 3 is connected with air collector 4, has reduced the pollution of gas to environment, and can waste utilization, reduced cost widely.
Be enlightenment with above-mentioned foundation desirable embodiment of the present utility model, by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
Claims (3)
1. an energy-saving LNG skid aerator comprises external frame and is fixed on the interior gas holder of external frame, and it is characterized in that: described gas holder top offers relief opening, and described relief opening is connected with air collector by conduit, is provided with air extractor in the described conduit.
2. energy-saving LNG skid aerator as claimed in claim 1, it is characterized in that: described conduit is provided with control valve.
