Description

TECHNICAL FIELD

[0001] The utility model belongs to hydrogen energy technical field, more particularly to a kind of to improve hydrogenation rate pry installation type pressurization hydrogenation device, it is applicable to green park, industrial concentration area and the hydrogenation of hydrogen energy and fast deployment demand of scene. BACKGROUND

[0002] With the transformation of global energy structure to clean and low carbon, hydrogen energy, due to its efficient and zero-emission characteristics, has become an important development direction in the energy field. China's goal of "carbon peak by 2030 and carbon neutrality by 2060" further promotes the rapid development of the hydrogen energy industry. The demand for hydrogen fuel cell vehicles, hydrogen energy forklifts and industrial hydrogen equipment is growing rapidly. As a key link in the hydrogen supply chain, the technical level of hydrogen refueling stations directly affects the promotion and application of hydrogen energy. However, existing hydrogen refueling station technology has significant shortcomings in hydrogenation rate, flexible deployment and operating efficiency, making it difficult to meet the diverse and dynamic hydrogen use scenarios.

[0003] Traditional hydrogen refueling stations are mostly designed as fixed installations, containing main components such as hydrogen storage tanks, compressors and hydrogenation equipment. This design has played a role in early hydrogen energy applications, but its limitations have gradually emerged. First, fixed hydrogen refueling stations have a long construction period, typically taking months to a year, and require a large amount of land, making it difficult to meet the rapid deployment needs of green parks or temporary hydrogen use scenarios. The connection of fixed structure modules mostly uses traditional flanges or welding methods, which takes a long time to install and remove, limiting the flexibility of the equipment in dynamic hydrogen use scenarios. For example, in industrial areas or experimental scenarios, fixed hydrogen refueling stations are difficult to quickly put into use, affecting the response speed of hydrogen refueling services.

[0004] In terms of hydrogen storage systems, existing hydrogen refueling stations mostly use single high-pressure tank structures, lacking dynamic adjustment capabilities. When hydrogen supply flow fluctuates, compressors need to be frequently started and stopped to maintain pressure, resulting in increased energy consumption and shortened equipment life. For example, in centralized hydrogen supply scenarios, dynamic changes between pipe bundle vehicle input and hydrogenation demand often lead to pressure imbalance in the hydrogen storage system, requiring additional adjustments to the compressor's operating state, which prolongs the preparation time before refueling. In addition, single-tank designs usually do not have flexible pressure monitoring and adjustment components such as hydraulic valves or buffer tanks, making it difficult to achieve precise control of the supply pressure, affecting the stability of downstream hydrogenation.

[0005] In terms of compression technology, existing hydrogen stations generally use electric-driven compressors that drive piston or screw compressors through electric motors. This design can still work under stable conditions, but it performs poorly under rapid pressure increase or load fluctuation. The start-stop response time of electric-driven compressors is relatively long, usually taking several seconds to tens of seconds, and frequent start-stop can cause significant electrical energy loss and mechanical wear. Some technologies attempt to introduce frequency converters to adjust motor speed, but their adjustment range is limited, making it difficult to respond to rapid pressure requirements under complex conditions. For example, when hydrogenation equipment suddenly needs high-pressure hydrogen (such as 12 MPa), electric-driven compressors are difficult to complete the pressure increase in a short time, resulting in reduced hydrogenation rate. In addition, electric-driven compressors are prone to high temperatures when running at high loads, requiring additional cooling systems, which increases the complexity and energy consumption of the device.

[0006] In terms of hydrogenation module design, existing hydrogen stations mostly support single pressure filling, making it difficult to meet the wide range of hydrogen requirements from low pressure (0.1 MPa) to high pressure (12 MPa). For example, hydrogen energy forklifts usually require 3-5 MPa low-pressure hydrogen, while hydrogen fuel cell logistics trucks may require 12 MPa high-pressure hydrogen. The single filling channel design needs to adjust the pressure frequently, prolonging the filling time. Some hydrogen stations attempt to introduce multi-stage filling channels, but their switching mechanisms mostly use manual or electromagnetic valves, which have slow response speed (switching time usually exceeds 1 second), making it impossible to achieve rapid pressure switching. In addition, the output interfaces of existing hydrogenation modules (such as hydrogenation guns) lack flexible connection designs, making it difficult to adapt to different types of hydrogen-using equipment, limiting the versatility of hydrogen stations.

[0007] In recent years, some technologies have attempted to improve hydrogen station design. For example, some documents have proposed skid-mounted hydrogen stations that shorten the construction period through modular integration, but their compressors still rely on electric drive, which lacks sufficient pressure increase efficiency and response speed, and the module connection mostly uses traditional fixed methods, limiting rapid deployment capabilities. Some other solutions introduce liquid-driven compressor technology, using hydraulic drive to replace electric drive to improve compression efficiency. However, these designs mostly remain at the basic application stage, lacking structural improvements for hydrogenation rate optimization. For example, existing liquid-driven compressor systems do not have efficient gas-liquid separation structures, which can cause gas-liquid mixing problems under high load operation, affecting compression stability. In addition, the tank design of hydrogen storage modules is usually simple, lacking common components such as pressure gauges or exhaust valves, making it difficult to meet the demand for dynamic hydrogen supply.

[0008] With the expansion of hydrogen energy application scenarios, such as centralized hydrogen supply in green park and temporary hydrogen use in industrial area, the existing hydrogen refueling station technology has been difficult to meet the requirements of rapid refueling, efficient deployment and wide range of adaptation. Especially in supporting complex working conditions (such as hydrogen fuel cell experiment), the pressurization speed and gas supply stability of traditional devices are insufficient, which limits the research and development and popularization of hydrogen energy technology. Therefore, a skid-mounted hydrogen refueling device based on liquid-driven pressurization technology is needed, which solves the limitations of existing technology through innovative hydrogen storage tank design, liquid-driven pressurization structure and multi-stage refueling channel, improves the hydrogen refueling rate and operation efficiency, and provides technical support for the large-scale development of hydrogen energy industry.
