Specific embodiment
A kind of Liquefied gas tanker residual air remnant liquid recovering device is suitable for the Liquefied gas tanker of a variety of media, below with the stone that liquefies
This covering device is introduced for oil gas tank car, which includes mobile storage container 1, residual air
Compression set 2 and fluid infusion apparatus, mobile storage container 1 is connect with residual air compression set 2 and tank car tank body 3 respectively, remaining
Air pressure compression apparatus 2 is used for the residual air boil down to liquefied gas in tank car tank body 3, residual air compression set 2 and fluid infusion apparatus point
It does not connect with tank car tank body 3, firstly, residual air compression set 2 extracts the gas in mobile storage container 1 to tank car tank body 3, makes
Pressure reduction in mobile storage container 1 forms pressure difference between tank car tank body 3 and mobile storage container 1；Then,
Using existing pressure difference between tank car tank body 3 and mobile storage container 1, the raffinate in tank car tank body 3 is made to be pressed into movable type
Storage container 1, until the raffinate conveying in tank car tank body 3 is finished；Finally, passing through fluid infusion apparatus to tank car tank body
Respective liquid is injected in 3, while starting the residual air that residual air compression set 2 extracts tank car tank body 3, by the liquid of residual air boil down to liquid
Mobile storage container 1 is pressed into after changing gas.
It is water that fluid infusion apparatus, which injects respective liquid into tank car tank body 3,.
As shown in Figure 1, mobile storage container 1 is connect by the first pipeline 4-1 with the blowdown valve 12 of tank car tank body 3,
There is the first valve 5-1 for controlling the pipeline on-off, residual air compression set 2 passes through the second pipeline 4-2 and tank on first pipeline 4-1

Gs-oil separator 10 is arranged in the outlet end of compressor 2-1.
Balanced valve 11 is set in residual air compression set 2, and the both ends of balanced valve 11 are connect with the both ends of compressor 2-1.
Whole device is in skid-mounted type.
Residual air compression condensation is liquefied gas by way of condensation by residual air compression set 2, and residual air compression set 2 includes pressure
The both ends of contracting machine 2-1 and condenser 2-2, compressor 2-1 by positive-negative connected valving 7 respectively with the second pipeline 4-2 and condensation
One end of device 2-2 connects, and the other end of condenser 2-2 is connect with third pipeline 4-3.
Residual air compression set 2 is the core of this recyclable device, and compressor 2-1 is by the low pressure residual air in tank car tank body 3
It is compressed into high pressure gas and is discharged into condenser 2-2, be filled with gas cylinder after liquid is converted into condenser 2-2.General tank car tank body 3
Interior low pressure residual air pressure is 0.2-0.3MPa (absolute pressure), and the pressure of compressor discharge gas has with liquefied gas type
It closes, by taking the liquefied gas of Yangtze petrochemical industry supply as an example, it is 1.5MPa (absolute pressure) that 40 DEG C of whens, which are saturation vapour pressure, is compressed at this time
Compression ratio needed for machine is 5~7.5.The liquefied gas recycle compressor that usual lpg filling station is selected, is mainly used for liquefied gas
Entrucking, unload, tank switching, occasions, the compression ratio such as canned are only 1.4~1.5, be unable to satisfy the requirement of gas recycling, therefore
The compressor of higher compression ratios has been selected in the present apparatus.The flow that the inspiratory flow of compressor is intake when can replace according to tank car
Selection, it is similar with flow of inlet water.
Since solubility of the liquefied gas to water is smaller, to prevent liquid from entering accidentally, " liquid hammer " occurs and damages compressor, this
Recyclable device has prepared efficient gas-liquid separator 9, prevents liquid and enters cylinder, it is ensured that the safe operation of compressor.
As shown in Fig. 2, gas-liquid separator 9 includes cylinder 9-1, float 9-2, stop valve 9-3 and tapping valve 9-4, cylinder 9-1

Disconnected stop valve 9-3, float 9-2 are column, are located in the inner cavity cylinder 9-1, if liquid enters gas-liquid separator 9, into cylinder
The liquid of 9-1 can make float 9-2 float, and float 9-2 closes stop valve 9-3 after touching stop valve 9-3, can enter liquid not
Compressor 2-1 is arranged in import and filters to avoid the fouls such as iron rust, welding slag in tank car tank body 3 from scurrying into compressor 2-1 with air-flow
Core 9-5, the lower end cylinder 9-1 have tapping valve 9-4, and the liquid into cylinder 9-1 is discharged by tapping valve 9-4.
The import of gas-liquid separator 9 is communicated with two position four-way valves, when gas enters filter core 9-5 by two position four-way valves, gas
Foul in body is trapped in outside the strainer of filter core 9-5, and clean gas then flows into gas-liquid separator by the screen drum inner hole of filter core 9-5
Cylinder 9-1 inner cavity, to ensure that the cleaning of the gas into compressor 2-1, extend compressor 2-1 uses the longevity
Life.
Liquefied gas can dissolve lubricating oil to some extent, easily bring lubricating oil into condenser 2-2, cause the collection of condensation segment
Oil influences the heat transfer effect of condenser 2-2, and lubricating oil flows into gas cylinder, increases the consumption of lubricating oil, therefore this recycling fills
It sets and is provided with gs-oil separator in the outlet end of compressor 2-1, primary structure is as shown in Figure 3:
Gs-oil separator 10 includes floating ball 10-2, the filler oil strain layer 10- in shell of tank 10-1 and shell of tank 10-1
3, the inner cavity of shell of tank 10-1 is divided into upper layer and lower layer, and floating ball 10-2 is located at the lower layer of inner cavity, and filler oil strain layer 10-3 is located at interior
The upper layer of chamber, the lower layer of inner cavity have an interlayer 10-4, and the upper layer side of shell of tank 10-1 has outlet, shell of tank
The same side of the lower layer of 10-1 has import, and import is communicated with interlayer 10-4, and high-pressure liquefaction gas enters shell of tank by import
The interlayer 10-4 of the lower layer of 10-1, and the side of the separate import from interlayer 10-4 enters the upper layer of inner cavity, into the upper of inner cavity
The liquefied gas of layer is discharged after filler oil strain layer 10-3 filtering by outlet, the lubrication oil droplet that filler oil strain layer 10-3 is filtered out
The lower layer of inner cavity locating for floating ball 10-2 is fallen into, the lower layer of inner cavity has ball-cock assembly 10-5, when on the liquid level of the lubricating oil of drippage
When being raised to certain altitude, floating ball 10-2, which floats, makes ball-cock assembly 10-5 open the lubricating oil that discharge filters down, the lubricating oil of discharge
It is back to compressor 2-1, if pasta drops to certain position, floating ball 10-2 decline presses ball-cock assembly 10-5 closing.Divide to improve
Oily effect uses molecular sieve structure in the filler oil strain layer of gs-oil separator, can drop the concentration of lubricating oil in liquefied gas
Down to 10ppm or so.
The effect of condenser 2-2 is that high pressure gas is condensed into liquid.In the present apparatus, because required condensation capacity is not
Greatly, so condenser 2-2 has selected forced convection air cooled condenser, its main feature is that installation cooling water is not needed, thus use,
It is all more convenient to move dress.Condenser 2-2 is made of several coiled pipes in parallel, and liquefied gas enters every snake by top distributing manifold
Pipe flows down along pipe after condensing into liquid, is compiled in lower collector pipe.The exothermic coefficient of the air side of forced convection air cooled condenser
It is smaller, therefore casing fin has been used outside pipe.To avoid coiled pipe lower part from being liquid filled, condensation effect is influenced, control is every
The length of root coiled pipe, the length of single coiled pipe are unsuitable too long.
