Wherein: on the pipeline between the output terminal and the inlet end of compressor of described exsiccator, knock out drum is installed, the inlet end of this knock out drum is connected with the output terminal of described exsiccator, an outlet side of described knock out drum is connected with the inlet end of compressor, and second outlet side is connected with described Water Tank; Described pressure regulation metering sledge, exsiccator, knock out drum, knockout drum, Water Tank, compressor and the pipeline between filling machine with gas storage well are all connected with air by exhausting pipeline.
Advantage of the present utility model and good effect are:
The utility model adopts knockout drum to replace recycling can, makes the gas-liquid separation of compressor unloading gas more thorough, effectively can reduce and reclaim gas impurities, ensure that the quality of compressed natural gas, improve turbidity test.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 1 is pressure regulation metering sledge, 2 is exsiccator, and 3 is knock out drum, and 4 is knockout drum, and 5 is Water Tank, and 6 is compressor, and 7 is sequence control dish, and 8 is filling machine, and 9 is gas storage well.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises pressure regulation metering sledge), exsiccator 2, knock out drum 3, compressor 6, sequence control dish 7, filling machine 8, gas storage well 9, knockout drum 4 and Water Tank 5, wherein the inlet end of pressure regulation metering sledge 1 is connected with upstream gas pipeline, outlet side is connected by the input end of pipeline with exsiccator 2, an output terminal of exsiccator 2 is connected by the inlet end of pipeline with at least one compressor 6, and second output terminal is connected with Water Tank 5 by pipeline.The compressor 6 of the present embodiment is two, and one of them is for subsequent use.The outlet side of two compressors 6 is connected respectively by the entrance of pipeline with sequence control dish 7, the outlet of sequence control dish 7 is connected with multiple gas storage well 9 and multiple filling machine 8 respectively by pipeline, and each gas storage well 9 is connected (filling machine 8 of the present embodiment be four, gas storage well 9 be six) respectively by pipeline with multiple filling machine 8.The input end of knockout drum 4 is connected to the sewage draining exit of two compressors 6 respectively by pipeline, an output terminal of knockout drum 4 is connected with Water Tank 5, second output terminal to be connected with the input end of pressure regulation metering sledge 1 by pipeline or by independent pipeline for rock gas personal in gas station provides source of the gas.Pipeline between the output terminal and the inlet end of compressor 6 of exsiccator 2 can add knock out drum 3, gas flow rate can be reduced, the inlet end of this knock out drum 3 is connected with the output terminal of exsiccator 2, an outlet side of knock out drum 3 is connected with the inlet end of two compressors 6 respectively, and second outlet side is connected with Water Tank 5.Pressure regulation metering sledge 1, exsiccator 2, knock out drum 3, knockout drum 4, Water Tank 5, compressor 6 and the pipeline between filling machine 8 with gas storage well 9 are all connected with air by exhausting pipeline.
Pressure regulation metering sledge 1 of the present utility model is commercial products, purchases in Feiao Gas Equipment Co., Ltd., Shanghai; Sequence control dish is commercial products, purchases in Sichuan Jinxing Compressor Manufacturing Co., Ltd..
Working principle of the present utility model is:
Compression aerating flow process: upstream line carrys out gas, enters exsiccator 2, carries out processed to rock gas after the filtration of pressure regulation metering sledge 1, pressure regulation, metering; Rock gas after dehydration enters knock out drum 3 again, reduces rock gas flow velocity to setting value; Rock gas through knock out drum 3 enters compressor 6 again, carries out gas compression; Rock gas after compression, through sequence control dish 7, when not having refueling, is the aerating of each gas storage well 9; When there being refueling, by each filling machine 8 directly to refueling.When after gas storage well 9 gassy, compressor 6 is shut down, and passing through filling machine 8 by gas storage well 9 is refueling.
Recovery process: after compressor 6 is shut down, compressor 6 cylinder unloading at different levels, unloads carrier gas and is automatically taken out of by the condensed fluid in cooler at different levels, introduces knockout drum 4 by blowdown, unloading pipeline.Now have and on a small quantity entered upstream inlet pipeline owing to reclaiming gas the gas pressure in this admission line is raised, the pressure governor cut-off valve closedown of pressure regulation metering sledge 1 li, gas no longer flows into upstream inlet pipeline.Along with blowdown, the continuous discharge of unloading carrier gas, the pressure of knockout drum 1 raises gradually, until blowdown, unloading terminate.In knockout drum, the gas-liquid of 1 is after being separated, and condensed fluid is deposited on gas-liquid separation pot bottom, and periodic exhaustion introduces Water Tank 5.After next compressor 6 is started shooting, upstream inlet pipeline pressure reduces, and the pressure governor cut-off valve of pressure regulation metering sledge 1 li is opened automatically, and the gas in knockout drum 4 flows into upstream inlet pipeline, after the gas pressure in knockout drum 4 and upstream inlet pipeline pressure balance, gas no longer flows out.
