DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-3 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0038] The embodiment of the present application discloses a cogeneration air compression system. Figure 1 The cogeneration air compression system includes: an air compressor 110, a gas-consuming device 120, a heat recovery subsystem 130, a monitoring component 140 and a control device 150. The gas-consuming device 120 is connected to the air outlet of the air compressor 110 through a connecting pipe.

[0039] Specifically, the air compressor 110 generally includes a compression chamber, a main rotor, a sub-rotor and a control module. The compression chamber is used to store compressed gas, and the main material can be a pressure-resistant material such as carbon steel or stainless steel. The main rotor and the sub-rotor are responsible for compressing the gas entering the air compressor 110. The main rotor and the sub-rotor can adopt a screw type or a piston type structure. The size of the main rotor and the sub-rotor can be selected according to the power of the air compressor 110. The control module is used to collect various operating data of the air compressor 110. The control module can further include a panel so that the staff can control the operation of the air compressor 110 through the control panel.

[0040] The heat recovery subsystem 130 is used to recover the heat energy generated during the operation of the air compressor 110. Generally speaking, the heat recovery subsystem 130 includes a heat exchanger, a heat storage component, and a transmission pipeline.

[0041] The monitoring component 140 is provided in the cogeneration system for monitoring the operation of the cogeneration system. Specifically, the monitoring component can be provided on a device in the cogeneration system, such as the air compressor 110, or on a pipeline of the cogeneration system.

[0042] In one example, the monitoring component 140 includes a temperature sensing component and / or a vibration sensing component installed on the surface of the air compressor, so that the temperature and vibration conditions of the air compressor 110 can be collected in real time, thereby helping to monitor the status of the air compressor 110 based on the temperature and vibration conditions of the air compressor 110, and further helping to manage the air compressor 110.

[0043] In another example, the monitoring component 140 also includes a flow rate sensor installed in the connecting pipe, so that the gas flow rate in the connecting pipe can be collected in real time, which can help monitor the connecting pipe based on the gas flow rate, such as: monitoring whether the pipe is blocked, which can help manage the connecting pipe.

[0044] Control device 150 includes a first communication interface 151, a second communication interface 152, and a third communication interface 153. First communication interface 151 is signal-connected to air compressor 110 for obtaining operating data from air compressor 110 and sending control instructions to air compressor 110. Second communication interface 152 is signal-connected to heat recovery subsystem 130 for controlling the operation of heat recovery subsystem 130. Third communication interface 153 is signal-connected to monitoring component 140 for obtaining monitoring data collected by monitoring component 140. In this way, control device 150 can obtain operating data from air compressor 110 and monitoring data collected by monitoring component 140, and control the operation of air compressor 110 and heat recovery subsystem 130.

[0045] The implementation principle of a cogeneration air compression system provided in an embodiment of the present application is as follows: the cogeneration air compression system includes an air compressor 110, a gas-consuming device 120, a heat recovery subsystem 130, a monitoring component 140 and a control device 150, wherein the gas-consuming device 120 is connected to the air outlet of the air compressor 110 via a connecting pipe; the heat recovery subsystem 130 is used to recover the heat energy generated during the operation of the air compressor 110; the monitoring component 140 is arranged in the cogeneration system to monitor the operation of the cogeneration system; the control device 150 is used to monitor the operation of the cogeneration system; the monitoring component 14 ... The control device 150 includes a first communication interface 151, a second communication interface 152 and a third communication interface 153. The first communication interface 151 is connected to the air compressor 110 by signal, and is used to obtain the working data of the air compressor 110 and send control instructions to the air compressor 110; the second communication interface 152 is connected to the heat recovery subsystem 130 by signal, and is used to control the operation of the heat recovery subsystem 130; the third communication interface 153 is connected to the monitoring component 140 by signal, and is used to obtain the monitoring data collected by the monitoring component 140. By adopting the above-mentioned technical solution, the control device 150 can obtain the operating parameters of the air compressor 110 and the monitoring data collected by the monitoring component 140 based on the signal connection with the air compressor 110 and the monitoring component 140. This can help to monitor the cogeneration air compression system in combination with the operating parameters and monitoring data. In addition, since the control device 150 can control the operation of the air compressor 110 and the heat recovery subsystem 130 based on the signal connection between the air compressor 110 and the heat recovery subsystem 130, this can facilitate the management of the cogeneration air compression system.

[0046] In some embodiments, reference Figure 2 The cogeneration air compression system also includes a dryer 160 arranged between the air compressor 110 and the gas-consuming equipment 120. The control device 150 also includes a fourth communication interface 154. The fourth communication interface 154 is signal-connected to the dryer 160 for controlling the operation of the dryer.

[0047] Specifically, the dryer 160 is used to reduce the moisture content of the compressed air to increase the dryness of the compressed air, thereby ensuring the normal operation of the gas-consuming equipment 120 .

[0048] In this embodiment, a dryer 160 is added between the air compressor 110 and the gas-consuming equipment 120, and the operation of the dryer 160 can be controlled by the control device 150, so that the operation of the cogeneration air compressor system can be easily managed.

[0049] In actual implementation, the dryer 160 can also send its own working data to the control device 150 through the fourth communication interface 154, so that the current working data of the dryer can be considered in the process of determining the control method of the dryer 160, which can help improve the accuracy of the control of the dryer 160.

[0050] In one example, reference Figure 2 A first gas tank is also connected between the air compressor 110 and the dryer 160. The monitoring assembly 140 includes a temperature monitoring assembly disposed within the first gas tank. This allows the temperature monitoring assembly to monitor the temperature of the gas within the first gas tank. Since the gas in the first gas tank originates directly from the air compressor 110, the heat recovery effectiveness of the heat recovery subsystem 130 can be monitored by the gas temperature.

[0051] In another example, refer to Figure 2 A second gas tank is connected between the dryer 160 and the gas-consuming device 120. The monitoring assembly 140 includes a humidity monitoring assembly disposed within the second gas tank. This allows the humidity monitoring assembly to monitor the humidity of the gas within the second gas tank. Since the gas in the second gas tank directly originates from the dryer 160, the drying effect of the dryer 160 can be monitored based on the humidity of the gas.

[0052] Furthermore, the monitoring component 140 may also include an air pressure monitoring component disposed in the first air tank and / or the second air tank. Thus, the air pressure monitoring component 140 can monitor the air pressure within the air tanks, thereby promptly detecting system anomalies, thereby helping to improve safety during the production process.

[0053] In some embodiments, reference Figure 3 The control device 150 further includes a wireless communication module 155 , which is used to communicate with the background management system 200 to send data to the background management system 200 and receive instructions sent by the background management system 200 .

[0054] Specifically, the backend management system 200 runs in a server and provides a user interaction page. Managers can access the user interaction page through electronic devices such as computers and terminals to obtain information in the backend management system 200.

[0055] In an example, the wireless communication module 155 may be a WiFi module, a cellular mobile communication module, or the like.

[0056] In the above embodiment, the control device 150 can send data to the background management system 200 and receive instructions sent by the background management system 200 through the wireless communication module 155. This can help the staff to remotely monitor the status of the cogeneration system through the background management system 200, as well as remotely control the cogeneration system.

[0057] In one example, the cogeneration air compression system further includes an alarm device 170, which is installed near the air compressor 110. The alarm device 170 is signal-connected to the backend management system 200 and is configured to receive alarm instructions issued by the backend management system 200. In the above technical solution, since the backend management system 200 can directly send alarm instructions to the alarm device 170 based on the communication connection between the backend management system 200 and the alarm device 170, this can help increase the speed of issuing alarm instructions. This allows the alarm device 170 to promptly send alarm prompt information to on-site personnel when a system anomaly occurs, thereby speeding up the handling of the anomaly.

[0058] Furthermore, the control device 150 also includes a fifth communication interface 156, which is signal-connected to the alarm device 170 and is used to send an alarm instruction to the alarm device 170. In this way, when the control device 150 detects an abnormality, it can directly send an alarm instruction to the alarm device 170 based on the direct signal connection with the alarm device 170 without going through the backend management system 200. This allows the most convenient alarm instruction issuance method to be selected according to actual needs, while also enhancing system redundancy and ensuring that alarm information can be accurately issued.

[0059] The above are only some of the implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
