Problems solved by technology
[0003] At present, most of the compressors used in hydrogen refueling stations use diaphragm compressors. Diaphragm compressors can be completely oil-free, and their compression ratios can also be large. However, limited by technology and materials, the flow rate of diaphragm compressors is only It can achieve a small flow range, but cannot provide high-pressure compressed hydrogen with a large flow rate; while the traditional piston compressor can achieve a large flow rate, but is limited by the sealing technology and cannot achieve a high compression ratio

The invention discloses a high-pressure compression device for a hydrogen refueling station. The high-pressure compression device specifically comprises a low-pressure hydrogen inlet pipeline, a high-pressure hydrogen outlet pipeline, at least one group of low-pressure-stage hydrogen compression devices, a hydraulic-driven compressor, a hydraulic-driven compressor gas inlet pipeline and a hydraulic-driven compressor exhaust pipeline, wherein the hydraulic-driven compressor gas inlet pipeline and the hydraulic-driven compressor exhaust pipeline are arranged on the hydraulic-driven compressor; the first group of low-pressure-stage hydrogen compression devices communicate with a low-pressure hydrogen inlet pipeline; the hydraulic-driven compressor exhaust pipeline communicates with the high-pressure hydrogen exhaust pipeline; pipelines are arranged between all the groups of low-pressure-stage hydrogen compression devices as well as between the last group of low-pressure-stage hydrogen compression device and the hydraulic-driven compressor gas inlet pipeline; each low-pressure-stage hydrogen compression device comprises a traditional piston type compressor and a gas cooler arranged on the traditional piston type compressor, and is responsible for compression of hydrogen in a low-pressure compression section within 15MPa; and the hydraulic-driven compressor is responsible for compression of hydrogen in a high-pressure compression section within 80 MPa. High-flow high-pressure compressed hydrogen can be provided, and the requirement of a hydrogen refueling station for high-flow high-pressure hydrogen processing is perfectly met.
Description
Technical field: [0001] The invention relates to the technical field of hydrogen refueling stations, in particular to a high-pressure compression device for hydrogen refueling stations. Background technique: [0002] With the vigorous development of clean energy in the country, people's demand for high-pressure hydrogen is increasing, and the daily hydrogen refueling capacity of hydrogen refueling stations is increasing. This requires compressors that can provide large flows of high-pressure compressed hydrogen to meet the increasing demand. . [0003] At present, most of the compressors used in hydrogen refueling stations use diaphragm compressors. Diaphragm compressors can be completely oil-free, and their compression ratios can also be large. However, limited by technology and materials, the flow rate of diaphragm compressors is only It can achieve a small flow range, but cannot provide high-pressure compressed hydrogen with a large flow rate; while the traditional pisto...
