At present, most of the high-pressure condensation compressor systems of polysilicon tail gas recovery devices are designed with two lines, and standby compressors are set in the single-line compression system. However, when abnormal conditions occur in the operating equipment during the maintenance period of the single-line faulty equipment, it will cause a single-line load and a decrease in production. In this regard, the high-pressure condensation compressor system of the tail gas recovery device adopts a two-line parallel method on the basis of mutual backup of single-line equipment to achieve full mutual backup of the two-line compressors, which largely solves the problems of restricting the stability of the production system and increasing the load due to reasons such as tail gas recovery treatment volume and equipment failures.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] The present utility model provides a reciprocating compressor mutual backup system as shown in Figure 1-2 which includes two inlet pipes 1;

[0036] At the right side position of the upper inlet pipe 1, an outlet connection valve A2 is provided. At the lower side position of the lower inlet pipe 1, a buffer tank A3 is provided. At the lower right side position of the outlet connection valve A2, a buffer tank C4 is provided;

[0037] At the lower side position of the buffer tank A3, a unit main body A5 is provided. At the lower side position of the buffer tank C4, a unit main body B6 is provided. At the lower connection position of the unit main body A5 and the unit main body B6, an outlet connection valve B7 is provided. At the lower side position of the unit main body A5, a buffer tank B8 is provided. At the lower side position of the unit main body B6, a buffer tank D9 is provided. The lower ends of the buffer tank B8 and the buffer tank D9 are respectively connected to an outlet pipe 10;

[0038] Data acquisition devices 11 are respectively provided in the unit main body A5 and the unit main body B6. The data acquisition devices 11 are connected to an external human-machine interface 12, and a communication device 13 is built in the human-machine interface 12;

[0039] The data acquisition devices 11 and the communication device 13 are respectively powered by connecting to an external power supply.

[0040] In this embodiment, the working principle is as follows:

[0041] Solution 1 (connection after buffer tank):

[0042] Independent air intake: Each compressor unit independently receives gas through the upper inlet pipe 1, ensuring that the two systems do not interfere with each other at the front end, which is beneficial to the stable operation of their respective systems.

[0043] Setting of the outlet connection valve A2: The outlet connection valve A2 is located at the right side position of the upper inlet pipe 1, that is, after the buffer tank. This design may have a certain impact on the balance of the gas path because the gas has been preliminarily processed by the buffer tank before entering the outlet connection valve A2.

[0044] Consideration of gas path balance: Since the gas enters the outlet connection valve A2 after passing through the buffer tank, special attention needs to be paid to the balance of the gas path during design and debugging to prevent the reduction of system efficiency or instability caused by uneven air flow distribution.

[0045] Solution 2 (connection before buffer tank):

[0046] Optimization of gas path distribution: The outlet connection valve A2 is set at the lower connection position of the unit main body A5 and the unit main body B6, that is, before the buffer tank. This design makes the gas path distribution more reasonable because the gas is distributed before entering the buffer tank, which helps to achieve a more uniform air flow distribution.

[0047] System mutual backup: By setting the outlet connection valve A2 in front of the buffer tank, the mutual backup function of the two compressor units can be better realized, because the gas has been effectively distributed and controlled before entering their respective buffer tanks.

[0048] Enhanced stability: Since the gas distribution and control occur before the buffer tank, this design helps to improve the stability of the entire system, especially when dealing with production load changes or equipment abnormalities.

[0049] Usage steps:

[0050] Startup preparation: Conduct a comprehensive inspection of all compressor units and their related components to ensure they are in good working condition, including buffer tanks, connection valves, sensors, etc.

[0051] System startup: According to the selected scheme (Scheme 1 or Scheme 2), start the compressor unit by controlling the corresponding linkage valve. For Scheme 1, attention needs to be paid to the balance adjustment of the gas path; for Scheme 2, the rationality of the gas path distribution needs to be concerned.

[0052] Real-time monitoring: Real-time monitor the operating status of the system through the human-machine interface 12, including key parameters such as pressure, temperature, and flow rate, to ensure that the system operates stably as expected.

[0053] Abnormality handling: Once an abnormality is detected in a certain compressor or the system, immediately switch to the standby unit through the linkage valve according to the characteristics of the selected scheme, and repair or maintain the abnormal unit.

[0054] Energy-saving scheduling: According to the actual production load and grid load conditions, adjust the operating mode of the compressor unit through the intelligent control system to achieve the best energy-saving effect.

[0055] Regular maintenance: Regularly maintain and inspect the system to ensure the good operating status of all equipment and components and extend the service life of the system.

[0056] By comprehensively considering the characteristics of Scheme 1 and Scheme 2, the most suitable design scheme can be selected according to the specific production environment and requirements to achieve the efficient operation of the high-pressure condensation compressor system of the tail gas recovery device.

[0057] Such as Figure 1-2As shown, the main unit A5 and the main unit B6 respectively include unit A, unit B, unit C, and unit D. The data acquisition device 11 is specifically a variety of sensors, and can input the sensing data into the data acquisition device 11. The human-machine interaction interface 12 is specifically a touch screen display and a monitoring screen. The communication device 13 is specifically a wireless communication module, realizing remote communication and monitoring between the system and an external data center or the cloud. The second solution of this system is to set the outlet connection valve A2 at the upper connection of the main unit A5 and the main unit B6.

[0058] Preferably, in the high-pressure condensation compressor backup system of this polysilicon tail gas recovery device, the data acquisition device 11, the human-machine interaction interface 12, and the communication device 13 together constitute the intelligent monitoring and management system of the system. Their specific usage principles and functions are as follows:

[0059] Data acquisition device 11

[0060] Usage principle:

[0061] A series of sensors are deployed in the system by the data acquisition device 11, such as pressure sensors, temperature sensors, flow sensors, etc. These sensors are distributed at key parts of the compressor unit to monitor various operating parameters in real time. The data collected by the sensors will be transmitted to the central control system for analysis and processing.

[0062] Function:

[0063] Real-time monitoring: The data acquisition device 11 can provide real-time data, reflecting the operating state of the compressor system, such as pressure fluctuations, temperature changes, etc., which helps to detect potential problems in a timely manner.

[0064] Fault warning: Through the analysis of the collected data, the system can predict and warn of upcoming faults, thus avoiding production interruptions.

[0065] Performance optimization: The accumulation and analysis of historical data help to optimize the working parameters of the compressor, improving the energy efficiency ratio and system stability.

[0066] Human-machine interaction interface 12

[0067] Usage principle:

[0068] The human-machine interaction interface 12 is usually a graphical touch screen display, through which the operator can interact with the system. The interface will display the real-time operating data, alarm information, system status, etc. of the compressor. The operator can perform operations such as parameter setting and system start-stop control through the interface.

[0069] Function:

[0070] Intuitive display: The human-machine interface 12 provides an intuitive operation platform, enabling the operator to quickly grasp the system status.

[0071] Convenient operation: The operator can easily control the system through the interface, such as starting / stopping the compressor, adjusting operation parameters, etc.

[0072] Alarm management: When an abnormality occurs in the system, the human-machine interface 12 will display alarm information to guide the operator in emergency handling.

[0073] Communication device 13

[0074] Principle of use:

[0075] The communication device 13 is mainly responsible for the two-way transmission of data in this system. On the one hand, it transmits the information collected by the data acquisition device 11 to the human-machine interface 12 and the central control system. On the other hand, it feeds back the processed instructions to the field devices. The communication device 13 usually supports multiple communication protocols to ensure the reliable transmission of data.

[0076] Function:

[0077] Remote monitoring: The communication device 13 enables the system to connect to an external data center or the cloud, realizing remote monitoring and management, and improving the flexibility and response speed of the system.

[0078] Data sharing: Through the communication device 13, the system can transmit data to an enterprise resource planning (ERP) system or other management systems to achieve data sharing and integration.

[0079] System upgrade: The communication device 13 also supports the remote update of software and firmware, facilitating the continuous upgrade and optimization of system functions.

[0080] Combined into this system, these three components together constitute a highly automated monitoring and management network, which not only improves the operation efficiency and security of the system, but also reduces the need for manual intervention and enhances the overall production automation level.
