Abstract
The utility model gives a kind of natural gas tank car residual gas recycling device, comprise pressure governor, knock out drum and compressor, pressure governor, knock out drum and compressor connect and compose recovery gas circuit by pipeline successively, the top reclaiming gas circuit is connected with natural gas tank car, and the end reclaiming gas circuit is connected with gas storage well.Rock gas remaining after utilizing this natural gas tank car residual gas recycling device natural gas tank car can be unloaded exports in gas storage well again, makes the pressure drop in natural gas tank car be low to moderate minimum 0.1MPa, so namely improves conveying efficiency, can reduce cost of transportation again.
Description
Technical field
The utility model relates to a kind of natural gas tank car residual gas recycling device.
Background technique
To be the compressed natural gas that shipped by natural gas tank car to be unloaded gas storage well being inflated automobile by filling machine through compressor in compressed natural gas substation, natural gas tank car is in the process of unloading, pressure in tank car becomes 2.0-3.0MPa from 250.0MPa, natural gas tank car at residue 2.0-3.0MPa time, natural gas substation compressor cannot work on due to the reason of the pressure change in tank car, at this moment will change tank car, tank car will be had to the about 600Nm that cannot use
3rock gas return refueling mother station, have in transportation process to making each natural gas tank car, with a large amount of rock gases, decrease the conveying efficiency of tank car, improve cost of transportation.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of structure natural gas tank car residual gas recycling device simple, with low cost.
For solving the problems of the technologies described above, the utility model provides a kind of natural gas tank car residual gas recycling device, comprise pressure governor, knock out drum and compressor, pressure governor, knock out drum and compressor connect and compose recovery gas circuit by pipeline successively, the top reclaiming gas circuit is connected with natural gas tank car, and the end reclaiming gas circuit is connected with gas storage well.
After adopting such structure, rock gas remaining after utilizing this natural gas tank car residual gas recycling device natural gas tank car can be unloaded exports in gas storage well again, make the pressure in natural gas tank car reduce minimum 0.1MPa, so namely improve conveying efficiency, can cost of transportation be reduced again.
In order to better understand technology contents of the present utility model, below by this natural gas tank car residual gas recycling device referred to as this recovering device.
The end that this recovering device reclaims gas circuit is also provided with safety check; After adopting such structure, prevent the rock gas adverse current entered in gas storage well.
Accompanying drawing explanation
Fig. 1 is the using state figure of this recovering device embodiment.
Embodiment
As shown in Figure 1
This recovering device comprises pressure governor 1, knock out drum 2 and compressor 3.
Pressure governor 1, knock out drum 2, compressor 3 and safety check 4 connect and compose recovery gas circuit by pipeline 5 successively.
Natural gas tank car 6 through classical pathway by the natural gas transport in natural gas tank car 6 to gas storage well 7, pressure drop in natural gas tank car 6 is low to moderate 2.0-3.0MPa, this recovering device is utilized to connect natural gas tank car 6 and gas storage well 7, the top reclaiming gas circuit is connected with natural gas tank car 6, the end reclaiming gas circuit is connected with gas storage well 7, and natural gas flow direction is arrow points direction in figure;
Rock gas in natural gas tank car 6 is through the pressure governor 1 of this recovering device, make its pressure become 0.017-0.025MPa, the rock gas changed after pressure enters in knock out drum 2, and the output gas pressure intensity of knock out drum 2 is stablized, through compressor 3, pressure is increased to 250MPa again, adds in gas storage well 7;
Pressure drop in final natural gas tank car 6 is low to moderate minimum 0.1MPa, so namely improves conveying efficiency, can reduce cost of transportation again.
The application is not only confined to gas storage well, can also be the storage facilities of other compressed natural gass, such as natural gas storage tank etc.
Above-described is only a kind of mode of execution of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model principle; can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
