Currently, a baffle wall is installed between the heating section and the preheating section of the furnace. The baffle wall is mostly water-cooled, but this has the following problems: 1. Leaks in the cooling water pipes can easily lead to major safety accidents; 2. Manual adjustment of the water valve opening is required, which is time-consuming and ineffective; 3. The baffle wall's condition needs to be confirmed on-site, making real-time monitoring impossible, and insufficient cooling can shorten its lifespan. Summary of the Invention

Compressed air is introduced into the inlet of the air storage tank, and the outlet of the air storage tank is connected to the cooling air pipes through an outlet pipe. An inlet temperature detection device is provided at the inlet of the cooling air pipe, and an outlet temperature detection device is provided at the outlet of the cooling air pipe. A regulating valve with a valve positioner is provided on the outlet pipe. The inlet temperature detection device, the outlet temperature detection device, and the regulating valve with a valve positioner are respectively connected to a PLC controller. The PLC controller automatically adjusts the opening of the regulating valve with a valve positioner based on the data collected by the inlet temperature detection device and the outlet temperature detection device.

[0005] The outlet pipe is also equipped with a flow detection device, which is located behind the regulating valve with a valve positioner and is connected to the PLC controller.

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0012] like Figure 1 As shown, a self-regulating air-cooled fire barrier system in this embodiment includes a water barrier 4, with two horizontally arranged cooling air pipes 5 passing through the water barrier 4, and the inlet and outlet ends of the cooling air pipes 5 protruding from the water barrier 4. An air storage tank 1 is located outside the water barrier 4. Compressed air is introduced into the inlet of the air storage tank 1, and the outlet of the air storage tank 1 is connected to the inlet end of the cooling air pipes 5 via an outlet pipe 10, allowing compressed air to flow into the cooling air pipes 5 through the outlet pipe 10 to cool the water barrier 4. The compressed air after heat exchange flows out through the outlet end of the cooling air pipes 5 and is collected. An inlet temperature detection device 8 is provided at the inlet of the cooling air pipes 5 to detect the temperature of the compressed air at the inlet of the cooling air pipes; an outlet temperature detection device 6 is provided at the outlet of the cooling air pipes 5 to detect the temperature of the compressed air at the outlet of the cooling air pipes. The outlet pipe 10 is equipped with a regulating valve 3 with a valve positioner and a flow detection device 7. The flow detection device 7 is located behind the regulating valve 3 with the valve positioner. The opening of the regulating valve with the valve positioner adjusts the compressed air flow rate of the outlet pipe. The flow detection device is used to monitor the compressed air flow rate. The outlet temperature detection device, the inlet temperature detection device, the flow detection device, and the regulating valve with the valve positioner are all connected to the PLC controller 2. The PLC controller automatically adjusts the opening of the regulating valve with the valve positioner based on the data collected by the inlet temperature detection device, the outlet temperature detection device, and the flow detection device, realizing real-time control of the firewall cooling effect and automatically adjusting the firewall cooling effect without the need for manual adjustment by the operator.

[0013] Pressure sensor 9 is installed on air tank 1. Pressure sensor 9 is connected to PLC controller 2. Pressure sensor 9 detects the pressure of compressed air in air tank 1 and feeds it back to PLC controller to ensure the stability of compressed air in air tank. Normal operating parameter ranges are set, and the collected data is compared with the set data to provide interlocking alarms for normal system operation, allowing operators to monitor the status of the firewall in real time.

[0014] The aforementioned inlet temperature detection device and outlet temperature detection device are both temperature sensors, and the flow detection device is a flow meter.

[0015] This application uses compressed air as the cooling medium to cool the firewall, avoiding safety accidents. The PLC controller automatically adjusts the opening of the regulating valve with a valve positioner based on temperature, flow rate, and pressure data, thereby regulating the flow rate of compressed air and achieving real-time control of the firewall's cooling effect. This reduces adjustment time and extends the firewall's service life. The detection data is displayed through a human-machine interface for easy monitoring by operators.

[0016] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
