Problems solved by technology

[0002] During the gas filling process, the liquid is filled by the plunger pump after being vaporized and heated. In actual operation, because the liquid gas has saturated pressure gas in the storage tank, the liquid gas is extracted by the plunger pump. When there are two phases of gas and liquid, if there is gas in the liquid, it will directly affect the pumping volume of the plunger pump, which will lead to low filling efficiency and increased product failure rate.
In order to solve the above technical problems, the method adopted by those skilled in the art is to discharge part of the gas that coexists with gas and liquid before the plunger pump. Although the pumping volume of the plunger pump is improved, there is a problem of waste of resources.

Embodiment 1

[0020] like figure 1 As shown, the present invention provides a residual liquid recovery and energy optimization system, including: a liquid gas storage tank 1, a second plunger pump 2, a residual liquid storage tank 3, a water cooling tower 4, a first plunger pump 5, a heat exchange 6, hydraulic turbine 7, water pump 8, pre-cooler 9 and air cooling tower 10.

[0021] The precooler 9 uses refrigerant R22.

[0022] The liquid inlet of the second plunger pump 2 is connected to the liquid gas storage tank 1 , and the liquid gas in the liquid gas storage tank 1 is pressed by the second plunger pump 2 after being vaporized and heated up for filling. The residual liquid storage tank 3 is provided with a first storage port 31 and a second storage port 32 . The first storage port 31 is connected to the liquid gas storage tank 1 , and the second storage port 32 is connected to the residual gas-liquid coexisting gas pipeline 11 of the tanker. The gas part of the gas-liquid coexistence...

Embodiment 2

[0033] like figure 2 As shown, Example 2 adds a residual residual liquid recovery tank 15 , a heat exchanger 16 and a third plunger pump 17 on the basis of Example 1.

[0034]Due to the limitation of circulating water temperature and the influence of pipeline flow rate and thermal insulation effect, the liquid phase gas discharged from the residual liquid storage tank 3 will still retain a part of the liquid phase gas after heat exchange in the heat exchanger 6. The present invention utilizes the residual residual liquid recovery tank. 15 Recover and store the remainder of this portion.

[0035] The residual residual liquid recovery tank 15 is connected to the refrigerant outlet of the heat exchanger 6 to recover the residual residual liquid discharged from the heat exchanger 6 . The liquid inlet of the third plunger pump 17 is connected to the liquid outlet of the residual residual liquid recovery tank 15 , the liquid outlet of the third plunger pump 17 is connected to the ...

And safety and environmental protection are realized.

Description

technical field [0001] The invention belongs to the technical field of gas filling, and in particular relates to a residual liquid recovery and energy optimization system. Background technique [0002] In the process of gas filling, the liquid is pressed by the plunger pump and then gasified and heated up. When there are two phases of gas and liquid, if there is gas in the liquid, it will directly affect the pumping volume of the plunger pump, which will lead to the problems of low filling efficiency and increased product failure rate. In order to solve the above technical problems, the method adopted by those skilled in the art is to discharge part of the gas in which the gas and liquid coexist before the plunger pump. Although the pumping volume of the plunger pump is increased, there is a problem of waste of resources. SUMMARY OF THE INVENTION [0003] In order to solve the above technical problems, the present invention provides a residual liquid recovery and energy o...
