Abstract
Proposed by the present invention is the method that the stage pressure segmentation of compressed natural gas station two fills container.Natural air-air source is connected with height pressuring machine respectively by outer net pipeline to compressed natural gas station by pipeline.Carrying out first, second two benches by relatively low and high pressuring machine, sequentially filling process completes charging operation.The present invention is sequentially filled by the segmentation of two stage pressures, solves the technical problem that compressed natural gas energy-conservation fills.With energy-conservation, it is safe the characteristics of.The method application of natural gas operations is suitably filled to container as compressed natural gas station.
Description
Technical field
Proposed by the present invention is that two stage pressures that energy field compressed natural gas station fills to container are segmented the sequentially side of filling
Method.
Background technology
Existing compressed natural gas station fills generally use single-stage high voltage system to container, is charged to 25MPa or so, exists
The shortcomings that be：Just during dress, container is in low-pressure state, and directly low pressure storage tank is filled using elevated pressurization machine, due to pressure difference very
Greatly, kinetic energy serious waste is caused.
The content of the invention
In order to overcome it is existing the shortcomings that existing is filled to natural gas vessel, the present invention proposes the stage pressure of compressed natural gas two
It is segmented sequentially methods for filling.This method is filled by natural gas segmentation.Solves the technical problem that natural-gas energy-saving fills.
Scheme is used by the present invention solves technical problem：
After natural air-air source is transported to natural pressure compression apparatus by outer net by delivery pipe
1st, the first stage fills：The pressuring machine for starting relatively low compressed capability fills, container be filled into gross pressure more than half；
2nd, second stage fills：The pressuring machine for starting high compression ability fills, until container is filled into pressure requirements.
Good effect, the present invention are sequentially filled by two benches high-low pressure, are solved the technology that natural-gas energy-saving fills and are asked
Topic.With energy-conservation, it is safe the characteristics of.The method application of container processes is suitably filled as compressed natural gas station.
Brief description of the drawings
Fig. 1 is invention schematic diagram
In figure, 1, compressed natural gas station drain sump 2, pressuring machine 2.1. first stage pressuring machines, 2.2. second stage adds
Press 3, compressed natural gas container.
Embodiment
According to the figure：
Natural air-air source by outer net by delivery pipe be transported to after natural gas station drain sump 1 respectively with pressuring machine 2.1,2.2
It is connected.
1st, the first stage fills：Start first order pressurising machine 2.1, container 3 is filled with lower pressure；
2nd, second stage fills：Start second level pressurising machine 2.2 and natural gas charging is carried out to container 3 with high pressure, until
Untill reaching requirement pressure.
Feature：
Container is sequentially filled using height two stage pressure compressed natural gas segmentation, energy compared with always being filled with continuous high-pressure
Power consumption is enough saved, reduces investment and operating cost.
The method of the present invention can fill compressed natural gas to multiple containers simultaneously, improve operating efficiency.
Pressed gas charging operation available for relevant industries.
Claims (1)
