Have clean system behind the buffer tank, including compressor, desicator and the pressure swing adsorption tower that connects gradually, gas storage well, buffer tank exit linkage compressor are connected to the pressure swing adsorption ware. The absorber covers in adding air gun rifle head or gas storage bottleneck, pneumatic motor, and the motor drives the fan rotation and form certain pressure in the absorber to produce high -velocity air, make remaining natural gas obtain retrieving and getting into the buffer tank. The gas storage well of the natural gas entering gas station after the purification reaches recycle's mesh. Remain recovery unit of natural gas can add the air gun air entrainment back that finishes at CNG, retrieve the natural gas of remaining adding air gun, gas holder mouth, the natural gas of having avoided containing the odorant is to diffusion around the gas station, has improved the availability factor of the natural gas.
Description
Technical field
The utility model relates to a kind of device reclaiming residual rock gas, specifically the device that reclaims of a kind of rock gas remained air filling gun and gas storage bottleneck.
Background technique
In the face of petroleum resources are deficient and the severe situation of environmental problem, China have adjusted energy strategy structure, increases and large-scale develops and utilizes natural gas resource, and development CNG automobile becomes the important channel of the solution energy and environmental problem.Pipe natural gas, before entering gas station, in order to security consideration, often needs to add the odorants such as tetrahydrothiophene.CNG air filling gun is after aerating, and the gas remained in around air filling gun head and air cylinder can be diffused in surrounding enviroment.Containing the gas accumulation of odorant around gas station, not only affect the physical and mental health of staff, also can waste natural gas resource, bring potential safety hazard to surrounding.
Summary of the invention
The utility model is in order to after solving the aerating of current CNG air filling gun, and the residual natural gas leakage of part, to the problem in surrounding environment, provides a kind of device that can reclaim residual rock gas.
For solving above technical problem, the technical solution adopted in the utility model is: a kind of recovering device of residual rock gas, comprises tubular adsorber, adsorber front end is open, back-end closure, adsorber rear end is connected to knock out drum by pipeline, and blower fan is equipped with at adsorber rear portion, and blower fan is connected with motor.
During use, adsorber is covered in air filling gun rifle head or gas storage bottleneck, pneumatic motor, driven by motor blower fan is rotated in adsorber and forms certain pressure, and produces high velocity air, makes the rock gas remained be recycled and enter knock out drum.
As preferred technological scheme, also comprise the compressor, exsiccator, pressure-swing absorber and the gas storage well that connect successively, knock out drum outlet connects compressor.Enter cleaning system reposefully after reclaiming natural gas via knock out drum, cleaning system forms primarily of compressor, exsiccator and pressure-swing absorption apparatus.Enter compressor after cushioning balance, after compressor pressurization, enter exsiccator, exsiccator is used for removing the moisture reclaimed in rock gas.Dried gas is after pressure-variable adsorption, and nitrogen-rich gas is discharged from tower top, and methane is attracted in sorbent, and methane-rich gas by discharging after step-down desorption at the bottom of tower.The gas storage well that rock gas after purification enters gas station reaches the object of recycling.
As the preferred technological scheme of another kind, the front end dress filter screen of described adsorber, prevents surrounding solid impurity to be mixed into.
The recovering device of residual rock gas described in the utility model can after the aerating of CNG air filling gun, and reclaim the rock gas remaining in air filling gun, gas holder mouth, the rock gas avoided containing odorant spreads around gas station.Not only can improve gas station surrounding environment, build good work climate, the potential safety hazard that residual gas accumulation causes around gas station can also be got rid of.The rock gas reclaimed, after purification, can re-use, improve the utilization efficiency of natural gas resource, reduce operating cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-adsorber, 2-knock out drum, 3-blower fan, 4-motor, 5-compressor, 6-exsiccator, 7-1-pressure-swing absorber I, 7-2-pressure-swing absorber II, 8-gas storage well, 9-air filling gun rifle head, 10-filter screen.
Embodiment
The recovering device of the residual rock gas shown in Fig. 1, comprises tubular adsorber 1, and adsorber 1 front end is open, back-end closure, and adsorber 1 rear end is connected to knock out drum 2 by pipeline, and blower fan 3 is equipped with at adsorber 1 rear portion, and blower fan 3 is connected with motor 4.Covered on by adsorber outside air filling gun rifle head 9, formed with annular space outside air filling gun rifle head 9 and between adsorber inwall, the residual gas accumulation around air filling gun rifle head is in this annular space.The front end dress filter screen 10 of adsorber 1, is used for filtering solid contaminants in case blocking pipe.While the aerating of CNG air filling gun is complete, pneumatic motor 4, can form certain pressure after motor 4 drives blower fan 3 High Rotation Speed in adsorber, and produces high velocity air by residual methane recovery.Can according to the working time of aerating flow set the utility model recovering device of air filling gun, after exceeding set time, reclaiming system is closed automatically, simple to operate, can reduce the labor intensity of aerating personnel, also reduce security risk simultaneously.
Have cleaning system after knock out drum, comprise the compressor 5, exsiccator 6 and the pressure-swing absorber that connect successively, pressure-swing absorber connects gas storage well 8, and knock out drum 2 exports and connects compressor 5.Rock gas after recovery enters knock out drum 2, enters compressor 5 after cushioning balance, after compressor 5 pressurizes, enter exsiccator 6, and exsiccator 6 is used for removing the moisture reclaimed in rock gas.Dried gas enters pressure-swing absorber I 7-1, and after pressure-variable adsorption, nitrogen-rich gas is discharged from tower top.After pressure-swing absorber I7-1 absorption is saturated, control system can make it enter desorption operation by valve transfer, and pressure-swing absorber II 7-2 starts absorption simultaneously.The valve that pressure-swing absorber is imported and exported is opened by control system or closes, and pressure-swing absorber is hocketed and adsorbs or desorption, ensure that the continuous circulation of pressure-swing absorption process runs.The rock gas of absorption is discharged after desorption bottom pressure-swing absorber II7-2, enters gas storage well 8 for gas station.
