Description
Technical field
The utility model is specifically related to a kind of CNG quick aerator of standing, particularly a kind of CNG of dual gas supply air inlet quick aerator of standing.
Background technique
The many modes with standard station, female station, substation in present CNG both domestic and external station are carried out separately, female station be build in from the city far away, from the nearer place of the rock gas person in charge, the standard station is to build the many cities of natural gas tube network arrangements in, and the substation is the city of building not or have less gas distributing system in.Because the self structure principle, the CNG station of prior art has the following disadvantages:
1. because the standard station separates construction with the substation, and floor space is very big, and system's input is many, cause waste and business efficiency low easily.
2. because standard station compressor mostly is the compressor of positive displacement, the air displacement of compressor is subjected to the influence of suction pressure bigger, when gas pressure in the pipeline is low, the CNG gas station does not satisfy the aerating demand, cause aerating speed slow, take place to such an extent as to add the situation of discontented gas, particularly comparatively obvious with gas peak or winter.
3. because the substation source of the gas is subjected to the influence of all many-sides such as female station equipment, transportation range, haulage device, and the substation source of the gas that has can't be guaranteed for a long time, makes the substation can't satisfy the demand of aerating, to such an extent as to can not aerating, thus cause the utilization efficiency of equipment low.
Summary of the invention
The utility model provides a kind of CNG of dual gas supply air inlet the quick aerator of standing, purpose is the technical problem that solves existing standard station and substation individualism, provide a kind of and promptly can satisfy the requirement of standard station, can satisfy simultaneously the device that the substation requires again, thereby effectively reduced the cost of investment of while construction standard station and substation, improved the utilization efficiency of equipment, improved the aerating speed at CNG station again greatly, guaranteed that CNG stands in the demand that all can fill it up with gas in any case for the CNG automobile.
The utility model technological scheme that adopts of dealing with problems is:
The CNG of the dual gas supply air inlet quick aerator of standing includes control cabinet, and standard station compressor one end links to each other with control cabinet, and the other end links to each other with program board, is provided with one-way valve between standard station compressor and program board.The other end of program board is connected with the entrance point of low pressure gas storage group, middle pressure gas storage group, high-pressure gas group respectively, and the outlet end of low pressure gas storage group, middle pressure gas storage group, high-pressure gas group links to each other with the entrance point of filling machine respectively.The rock gas trailer is connected with discharge column, and discharge column is connected with the substation compressor, and compressor one end in substation links to each other with control cabinet, and the other end is connected with middle pressure gas storage group, the entrance point of high-pressure gas group and the entrance point of filling machine respectively.
The beneficial effects of the utility model: CNG standard station and substation are united two into one, complement one another, when normal the use, use standard station compressor as far as possible, when gas pressure is not enough in gas peak or winter pipeline, replenish with the substation; Or normal when using the substation compressor, because trailer pressure is low or when not having source of the gas, replenish with the standard station; Standard station and substation compressor are worked simultaneously when the aerating peak, thereby satisfy the quick aerating of CNG gas station, accomplish that promptly air displacement is variable when air inlet is constant; Thereby effectively reduce the investment and the operating cost at CNG station.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
The CNG of the dual gas supply air inlet as shown in fig. 1 quick aerator of standing includes control cabinet 9, and standard station compressor 1 one ends link to each other with control cabinet 9, and the other end links to each other with program board 3, is provided with one-way valve 2 between standard station compressor 1 and program board 3.The other end of program board 3 is connected with the entrance point of low pressure gas storage group 4, middle pressure gas storage group 5, high-pressure gas group 6 respectively, and the outlet end of low pressure gas storage group 4, middle pressure gas storage group 5, high-pressure gas group 6 links to each other with the entrance point of filling machine 7 respectively.Rock gas trailer 10 is connected with discharge column 11, and discharge column 11 is connected with substation compressor 12, and compressor 12 1 ends in substation link to each other with control cabinet 9, and the other end is connected with the entrance point of middle pressure gas storage group 5, high-pressure gas group 6 and the entrance point of filling machine 7 respectively.
Working principle: the quick aerator technological process of dual gas supply air inlet is to improve on the basis of CNG standard station and substation aerating technological process, form through optimal design, the corresponding valve of increase with a cover CNG standard station compressor and a cover substation compressor assembly, two cover systems promptly can be distinguished independent operating, can move simultaneously again, thereby increased the tolerance that adds at whole C NG station, have more rock gas to join in the CNG automobile in the unit time, concrete workflow is:
The A:CNG standard station flow process that works alone: from the rock gas → standard station compressor 1 supercharging compression → one-way valve 2 → program board 3 of pipeline → minute be clipped to high pressure air storage group 6, middle pressure air storage group 5, low pressure air storage group 4 → filling machine 7 → CNG automobile 8, the control of whole controlled process system cabinet 9.
The B:CNG substation flow process that works alone: rock gas trailer 10 → discharge column 11 → substation compressor 12 superchargings compression → minute be clipped to high pressure air storage group 6, middle pressure air storage group 5 → filling machine 7 → CNG automobile 8, the control of whole controlled process system cabinet 9.
C: the dual gas supply air inlet is workflow simultaneously:
From the rock gas of pipeline → standard station compressor boost compression 1 → one-way valve 2 → program board 3 → minute be clipped to high-pressure gas group 6, middle pressure gas storage group 5, low pressure air storage group 4.
Above-mentioned CNG standard station compressor and substation compressor enter into natural gas → filling machine 7 → CNG automobile 8 that high-pressure gas group 6, pressure gas storage group 5, low pressure air storage group 4 pool together respectively; The control of whole controlled process system cabinet 9.
CNG standard station and substation are united two into one, complement one another, when normal the use, use standard station compressor as far as possible, when gas pressure is not enough in gas peak or winter pipeline, replenish with the substation; Or normal when using the substation compressor, because trailer pressure is low or when not having source of the gas, replenish with the standard station; Standard station and substation compressor are worked simultaneously when the aerating peak, thereby satisfy the quick aerating of CNG gas station, accomplish that promptly air displacement is variable when air inlet is constant; Thereby effectively reduce the investment and the operating cost at CNG station.
