Description

Technical Field

[0001] This invention relates to the field of gas compression technology, and specifically to a gas compression system. Background Technology

[0002] Gas compression systems play a vital role in modern industrial production and scientific research, and are widely used in many fields such as petrochemicals, energy extraction, food processing, pharmaceuticals, and electronics manufacturing. However, traditional gas compression systems have revealed a series of problems that urgently need to be solved during actual operation.

[0003] Early gas compression equipment mostly adopted a decentralized layout, with each component, such as the compressor, heat exchanger, and filter, operating independently and installed in different locations. This layout resulted in a large footprint, cumbersome installation and commissioning processes, and significant costs in manpower, resources, and time. Moreover, the long pipelines connecting the decentralized components not only increased the risk of gas leaks but also caused substantial pressure losses during gas transmission, reducing the overall efficiency of the compression system.

[0004] From the perspective of gas processing flow, traditional systems suffer from poor continuity. After initial compression by the compressor, gas often fails to enter subsequent filtration, heat exchange, and buffering stages in a timely and effective manner, resulting in insufficient coordination between components. For example, due to a lack of proper process planning, gas may carry excessive impurities before entering the filter, leading to frequent filter clogging and requiring frequent cleaning or filter element replacement, severely impacting production continuity and equipment lifespan. Simultaneously, poor coordination between the heat exchange and compression stages causes excessively high gas temperatures during compression, affecting compression efficiency and potentially damaging the equipment.

[0005] Traditional gas compression systems also have significant shortcomings in terms of gas flow and pressure stability. When gas flow or pressure fluctuates, there is a lack of effective buffering mechanisms, which can impact critical equipment such as booster pumps, shortening their lifespan. Furthermore, it is difficult to guarantee stable output gas flow and pressure, failing to meet the production needs of industries with stringent gas quality requirements, such as pharmaceuticals and semiconductor electronics. These industries have extremely high standards for gas purity and pressure stability, and traditional systems struggle to provide a reliable gas supply.

[0006] Furthermore, traditional gas compression systems are difficult to maintain and manage. Due to the dispersed components and lack of modular design, if a component fails, maintenance personnel need to spend a significant amount of time troubleshooting, and the entire system may need to be shut down during the repair process, affecting production schedules. At the same time, traditional systems rely on relatively outdated detection methods, making it impossible to monitor gas parameters accurately and in real time, hindering the timely detection of gas quality issues and the implementation of appropriate measures.

[0007] In summary, with the continuous advancement of industrial technology and the increasing demands for gas compression quality and efficiency across various industries, the development of a novel gas compression system that is compact, efficient, stable in operation, and easy to maintain and manage is urgently needed. The gas compression system disclosed in this utility model is designed to solve many of the problems of the aforementioned traditional systems, aiming to provide a more reliable and efficient gas compression solution for modern industrial production and scientific research activities. Utility Model Content

[0008] The purpose of this invention is to solve the problems existing in the prior art. This invention provides a gas compression system in which the components work closely together, and the gas passes through compression, filtration, heat exchange, buffering and detection in sequence, ensuring that the gas is accurately processed at each stage and greatly improving the overall efficiency of gas compression.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a gas compression system, comprising an integrated housing, wherein an inlet pipe, an outlet pipe, a compressor module, a booster pump module, a heat exchange system, and a gas buffer system are provided inside the integrated housing;

[0010] The heat exchange system includes an inlet heat exchanger and an outlet heat exchanger.

[0011] The gas buffer system includes an inlet buffer and an outlet buffer.

[0012] The gas filtration system includes an inlet filter and an outlet filter;

[0013] The intake pipe, compressor module, intake filter, intake heat exchanger, intake buffer, booster pump module, outlet heat exchanger, outlet buffer, outlet detection module, outlet filter, and outlet pipe are connected along the gas flow direction through a gas transmission pipeline.

[0014] To further optimize this utility model, the following technical solutions may be preferred:

[0015] Preferably, the booster pump module includes one or more of the following: a hydraulically driven gas compressor, a linear motor driven gas compressor, a screw motor driven gas compressor, and an electric cylinder driven gas compressor.

[0016] Preferably, the booster pump module includes multiple multi-stage gas compressors connected in series or parallel, the gas buffer system further includes interstage buffers, the heat exchange system further includes interstage heat exchangers, and interstage buffers and interstage heat exchangers are provided between adjacent gas compressor stages.

[0017] Preferably, the gas outlet pipeline is further provided with a gas-oil separator, and the gas outlet valve is provided at the gas outlet of the gas outlet pipeline.

[0018] Preferably, the integrated housing is further provided with a detection module, which includes a temperature detection system and a pressure detection system.

[0019] Preferably, the intake pipe is equipped with a high-precision flow sensor and an electric regulating valve, which can automatically and accurately adjust the intake flow according to the real-time operating status of the system and the back-end processing requirements; the outer walls of the intake pipe, the outlet pipe and the transmission pipe are integrated with distributed sensors to monitor the pipe operating status in real time.

[0020] Preferably, the inlet heat exchanger is provided with a counter-current cross heat exchange structure, and the inlet filter includes a multi-layer composite filter layer and an electrostatic adsorption layer; the outlet heat exchanger is provided with a phase change material auxiliary heat exchange layer. When the gas temperature is too high, the phase change material auxiliary heat exchange layer absorbs heat and undergoes a phase change to store heat; when the gas temperature is low, the phase change material auxiliary heat exchange layer releases heat to assist in heating the gas.

[0021] The beneficial effects of this utility model are:

[0022] (1) High-efficiency gas compression process

[0023] The optimized gas processing path—including the inlet pipeline, compressor module, inlet filter, inlet heat exchanger, inlet buffer, booster pump module, outlet heat exchanger, outlet buffer, outlet detection module, outlet filter, and outlet pipeline—is connected along the gas flow direction via a gas delivery pipeline, creating a continuous and efficient gas processing flow. All components work closely together, with the gas sequentially passing through compression, heat exchange, buffering, filtration, and detection stages, ensuring precise processing at each stage and significantly improving the overall efficiency of gas compression. Compared to traditional decentralized and discontinuous gas compression equipment, this significantly reduces the gas residence time within the system and increases the gas throughput per unit time.

[0024] Synergistic Enhancement of Compression Efficiency: The compressor module initially compresses the gas, laying the foundation for subsequent processing, while the booster pump module further increases the gas pressure. The two modules are connected in an orderly manner through gas pipelines, achieving efficient seamless transitions between different stages of pressurization. The inlet and outlet heat exchangers exchange heat before and after gas compression, effectively controlling the gas temperature and preventing excessive temperature from affecting compression efficiency and equipment performance. This synergistic working method makes energy utilization more rational during gas compression, resulting in a significantly higher compression efficiency than when individual components operate alone or in simple combinations.

[0025] (II) Stable and reliable operation guarantee

[0026] Multiple buffers stabilize airflow: The inclusion of inlet and outlet buffers effectively addresses fluctuations in gas flow and pressure. Before gas enters the booster pump module, the inlet buffer stores excess gas and stabilizes pressure, preventing sudden changes in flow and pressure from impacting the booster pump and extending its service life. The outlet buffer ensures stable flow and pressure of the processed gas at the output, providing a reliable gas source for subsequent use, guaranteeing production continuity, and reducing product quality issues or equipment malfunctions caused by unstable airflow.

[0027] Precise filtration and testing ensure quality: The inlet and outlet filters employ a multi-layer filtration structure, effectively removing impurities, particles, and other contaminants from the gas, protecting internal system components from damage, and guaranteeing the purity of the output gas. The outlet gas detection module monitors parameters such as gas pressure, flow rate, temperature, and purity in real time. Upon detecting any anomalies, it provides timely feedback and takes appropriate measures to ensure that the output gas consistently meets high standards. This provides a reliable gas source for industries with stringent gas quality requirements, such as pharmaceuticals and semiconductor electronics.

[0028] (iii) Convenient maintenance and management

[0029] Integrated enclosure design: Integrating all key components into one unit significantly reduces the equipment's footprint and facilitates installation and commissioning. Simultaneously, the components are connected via gas pipelines, resulting in a compact and orderly layout that facilitates routine inspections and maintenance by maintenance personnel. Compared to traditional, dispersed gas compression equipment, this reduces the time spent locating fault points and connecting pipelines during maintenance, lowers maintenance costs, and improves equipment maintainability.

[0030] Modular components: Each component in the system, such as the compressor module, heat exchange system, and gas buffer system, has a relatively independent function and is connected through gas pipelines, forming a modular structure. When a component fails, the module can be directly disassembled, repaired, or replaced without affecting the normal operation of other components, greatly reducing equipment downtime and improving production efficiency.

[0034] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figure 1-2 As shown, a gas compression system includes an integrated housing 1, in which an inlet pipe 2, an outlet pipe 3, a compressor module, a booster pump module 4, a heat exchange system 6, and a gas buffer system 5 are installed.

[0037] The heat exchange system includes an inlet heat exchanger and an outlet heat exchanger.

[0038] The gas buffer system includes an inlet buffer and an outlet buffer;

[0039] The gas filtration system includes an inlet filter and an outlet filter;

[0040] The intake pipe, compressor module, intake filter, intake heat exchanger, intake buffer, booster pump module, outlet heat exchanger, outlet buffer, outlet detection module, outlet filter, and outlet pipe are connected along the gas flow direction through the gas delivery pipe 7.

[0041] As a preferred embodiment, the booster pump module includes one or more of the following: a hydraulically driven gas compressor, a linear motor-driven gas compressor, a screw motor-driven gas compressor, and an electric cylinder-driven gas compressor. This diversified driving method allows for flexible selection of the most suitable drive type based on different operating conditions and energy resources, optimizing the operating efficiency of the booster pump module. For example, in scenarios requiring extremely high power output stability, a linear motor-driven gas compressor can precisely control piston movement to ensure a smooth boosting process; while in environments where hydraulic power is the primary energy source, a hydraulically driven gas compressor can efficiently utilize existing energy, improving the overall system energy efficiency.

[0042] In a preferred embodiment, the booster pump module includes multiple multi-stage gas compressors connected in series or parallel. The gas buffer system also includes interstage buffers, and the heat exchange system includes interstage heat exchangers. Interstage buffers and interstage heat exchangers are installed between adjacent gas compressor stages. The interstage buffers effectively absorb pressure fluctuations in the gas after compression in the previous stage, preventing unstable airflow from impacting the next stage compressor and extending the compressor's service life. The interstage heat exchangers can promptly cool the high-temperature gas after compression, reducing the load on the next stage compressor and improving compression efficiency. Through this synergy of multi-stage compression and interstage processing, the gas can be gradually compressed to the target pressure in multiple stages, making the entire process more stable and efficient. Compared to single-stage compression, this significantly increases the compression ratio and gas throughput.

[0043] As a preferred embodiment, an oil-gas separator is also installed on the gas outlet pipeline, and a gas outlet valve is installed at the gas outlet of the gas outlet pipeline. The oil-gas separator on the gas outlet pipeline can effectively separate impurities such as oil droplets that may be carried in the gas, further improving the purity of the output gas, and providing a reliable gas source guarantee for industries with strict requirements for gas quality, such as pharmaceuticals and electronic semiconductors.

[0044] In a preferred embodiment, the integrated enclosure also houses a hydraulic system 9 and a detection module 8. The detection module 9 includes a temperature detection system and a pressure detection system. These detection methods can promptly detect abnormalities in system operation, such as excessively high gas temperature, excessive pressure fluctuations, and pipeline leaks, and quickly issue alarms. This not only helps ensure the safe and stable operation of the system but also provides data support for preventative maintenance, identifies potential faults in advance, and avoids production interruptions caused by sudden equipment failures.

[0045] In a preferred embodiment, a high-precision flow sensor and an electric regulating valve are installed on the intake pipe, which can automatically and precisely adjust the intake flow rate according to the real-time operating status of the system and the back-end processing requirements. Distributed sensors are integrated on the outer walls of the intake, outlet, and delivery pipes to monitor the pipe operating status in real time. The high-precision flow sensor and electric regulating valve on the intake pipe automatically and precisely adjust the intake flow rate according to the real-time operating status of the system and the back-end processing requirements. When the system load changes, it can quickly respond and adjust the intake volume to ensure that all components are always in optimal working condition. For example, when a failure occurs in the back-end booster pump module or compressor module, causing a decrease in processing capacity, this regulating device can automatically reduce the intake flow rate to prevent gas accumulation in the system, ensuring stable system operation while maintaining stable output gas quality.

[0046] In a preferred embodiment, the inlet heat exchanger is equipped with a counter-current cross-heat exchange structure. The inlet filter includes a multi-layer composite filter layer and an electrostatic adsorption layer. The outlet heat exchanger is equipped with a phase change material (PCM) auxiliary heat exchange layer. When the gas temperature is too high, the PCM auxiliary heat exchange layer absorbs heat and undergoes a phase change, storing heat. When the gas temperature is low, the PCM auxiliary heat exchange layer releases heat to assist in heating the gas. The multi-layer composite filter layer and electrostatic adsorption layer of the inlet filter filter the gas from coarse to fine, intercepting not only conventional impurities and particles but also adsorbing tiny aerosol particles and some harmful gas molecules, greatly improving the purity of the inlet gas and protecting subsequent components from contamination. The counter-current cross-heat exchange structure of the inlet heat exchanger increases the complexity of the heat exchange area and path, effectively reducing the inlet gas temperature and creating favorable conditions for the subsequent compression stage. The PCM auxiliary heat exchange layer on the outlet heat exchanger can automatically adjust the heat exchange according to the gas temperature, ensuring that the output gas temperature remains stable within a suitable range, meeting the stringent gas temperature requirements of different application scenarios. In addition, the gas-oil separator on the gas outlet pipeline can effectively separate impurities such as oil droplets that may be carried in the gas, further improving the purity of the output gas and providing a reliable gas source guarantee for industries with stringent gas quality requirements, such as pharmaceuticals and electronic semiconductors.

[0047] Based on the above technical solutions, the construction process of the gas compression system in this embodiment is as follows:

[0048] I. Overall System Layout

[0049] Integrated enclosure design: A robust and well-sealed integrated enclosure is custom-designed, using high-strength stainless steel or aluminum alloy materials to ensure excellent pressure resistance and corrosion resistance, adapting to various working environments. The internal space layout is rationally planned according to the dimensions and connection requirements of each component, ensuring compact installation and easy maintenance.

[0050] Component installation:

[0051] Secure the inlet and outlet air pipes to suitable positions on both sides of the enclosure to ensure smooth gas flow and secure pipe connections. Install quick-connect fittings or flanges at the inlet and outlet of the inlet air pipes for easy connection to external pipelines.

[0052] The compressor module is installed near the intake pipe to facilitate the rapid intake of gas to be compressed. Depending on the type of compressor selected, ensure it is securely installed and that vibration damping measures are in place to reduce vibration and noise transmission during operation.

[0053] The booster pump module should be installed in a suitable location inside the housing, depending on the selected drive type (e.g., hydraulic drive, linear motor drive, etc.). If multiple multi-stage gas compressors are used in series or parallel, they should be installed sequentially according to the gas flow direction, with sufficient space reserved between adjacent gas compressor stages for installing interstage buffers and interstage heat exchangers.

[0054] The inlet and outlet heat exchangers in the heat exchange system are installed near the compressor module outlet and booster pump module outlet, respectively, to achieve efficient heat exchange between the gases before and after compression. The counter-current cross-heat exchange structure of the inlet heat exchanger must be precisely installed according to design requirements to ensure effective heat exchange. The phase change material auxiliary heat exchange layer of the outlet heat exchanger must be securely installed and well-sealed to prevent leaks during operation.

[0055] The inlet buffer of the gas buffer system is installed after the inlet heat exchanger, near the inlet of the booster pump module; the outlet buffer is installed after the outlet heat exchanger, near the outlet detection module. If an interstage buffer is used, it must be installed strictly according to the positions of the two adjacent gas compressor stages to ensure buffering effectiveness.

[0056] The inlet filter of the gas filtration system is installed after the compressor module and before the inlet heat exchanger; the outlet filter is installed after the outlet buffer and before the outlet pipeline. The multi-layer composite filter layer and electrostatic adsorption layer of the inlet filter should be installed in sequence from coarse to fine to ensure filtration effectiveness.

[0057] The exhaust gas detection module is installed after the exhaust gas filter to facilitate real-time monitoring of various parameters of the gas before it is output. The detection module includes a temperature detection system and a pressure detection system, ensuring accurate sensor installation and enabling real-time and precise detection of gas temperature and pressure.

[0058] On the outlet pipeline, an oil-gas separator is installed near the outlet filter to separate impurities such as oil droplets that may be carried in the gas. An outlet valve is installed at the outlet for easy control of gas output.

[0059] II. Component Connection

[0060] Gas pipeline connection: Select high-strength gas pipelines that meet the pressure rating requirements, such as stainless steel pipes or high-pressure rubber hoses. Connect the inlet pipeline, compressor module, inlet filter, inlet heat exchanger, inlet buffer, booster pump module, outlet heat exchanger, outlet buffer, outlet filter, outlet detection module, and outlet pipeline sequentially along the gas flow direction. Ensure tight pipeline connections using appropriate connection methods such as welding, threaded connections, or compression fittings, and perform sealing treatment to prevent gas leakage. For connections between multi-stage gas compressors, as well as connections between interstage buffers and interstage heat exchangers and compressors, ensure that the connections are secure and well-sealed.

[0061] Control wiring connections: For high-precision flow sensors and electric regulating valves on the intake pipeline, as well as distributed sensors integrated into the outer walls of the intake, outlet, and delivery pipelines, corresponding control wiring needs to be laid and connected to the system's control center. Ensure correct wiring connections and stable signal transmission to achieve automatic and precise adjustment of the intake airflow and real-time monitoring of pipeline operating status. Simultaneously, connect the signal lines of the temperature and pressure detection systems in the detection module to the control center for real-time monitoring and data processing of gas parameters.

[0062] III. System Debugging and Operation Management

[0063] Commissioning Preparation: After system installation, carefully check the installation location and connections of each component, as well as the correctness of the control circuit connections. Perform a thorough cleaning of the system, removing impurities and dust from the pipes. Check the levels of lubricating oil, coolant, and other fluids in each device to ensure they are within normal operating conditions.

[0064] Debugging process:

[0065] First, start the compressor module and check its operating status, including speed, noise, and vibration, to ensure that the compressor is working properly. Then, gradually introduce the gas to be compressed, and adjust the intake flow to the appropriate range through a high-precision flow sensor and an electric regulating valve on the intake pipeline.

[0066] Observe the gas flow within the system, and sequentially check the operating status of components such as the inlet filter, inlet heat exchanger, inlet buffer, booster pump module, outlet heat exchanger, outlet buffer, outlet detection module, and outlet filter. Check the operation of the interstage buffer and interstage heat exchanger during the operation of the multi-stage gas compressor to ensure that all components work together normally.

[0067] The detection module monitors gas parameters such as temperature and pressure in real time. Based on system operation, the flow rate and temperature of the cooling medium in the heat exchange system, as well as the operating parameters of the booster pump module, are adjusted to ensure that the gas temperature and pressure parameters meet design requirements during the compression process. Simultaneously, the separation effect of the gas-oil separator and the flexibility and reliability of the outlet valve's opening and closing are checked.

[0068] Operation and Management: During normal system operation, regularly inspect and maintain all components. Check gas pipelines for leaks, corrosion, etc., and replace damaged pipes or seals promptly. Regularly clean or replace the filter elements of the inlet and outlet air filters to ensure filtration effectiveness. Monitor the heat exchange efficiency of the heat exchange system, clean the surface of the heat exchangers promptly, and ensure normal circulation of the cooling medium. Perform regular maintenance on equipment such as the booster pump module and compressor module, check the lubrication of the equipment and the wear of parts, and replace vulnerable parts promptly. Simultaneously, monitor gas parameters and pipeline operating status in real time through the detection module, establish operating data records, and promptly identify and resolve potential problems to ensure long-term stable and efficient system operation.

[0069] Through the above specific implementation methods, a gas compression system that meets design requirements can be constructed efficiently and stably, providing a reliable supply of compressed gas for various industries.

[0070] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
