[0021] The dry quenching furnace 1, the primary dust removal device 2, the boiler 4, the secondary dust removal device 5, the circulating fan 7 and the heat exchanger 8 are connected in sequence through pipelines, and the heat exchanger 8 is connected to the dry quenching furnace 1 through a pipeline.

[0022] The ash hopper I3 is connected below the primary dust removal equipment 2, and the ash hopper II6 is connected below the secondary dust removal equipment 5.

[0023] The pressure sensor 9 , the material level sensor 10 and the temperature sensor 11 are all connected to the controller 12 via an interface module.

[0024] The controller 12 adopts a PLC controller, and the interface module adopts an IM153 module used in conjunction with the PLC controller.

[0025] The centralized control center is connected to the operator station 13 via an HDMI cable, and the remote control terminal is connected and communicated with the operator station 13 via the Internet.

[0026] Specifically, Figure 1 to Figure 2As shown, the dry quenching and dust removal system includes a dry quenching furnace 1, a primary dust removal device 2, a boiler 4, a secondary dust removal device 5, a circulating fan 7 and a heat exchanger 8. These components are connected in sequence through pipelines to form the basic structure of the dry quenching and dust removal system. A pressure sensor 9 is installed on the inlet and outlet pipelines of the primary dust removal device 2 and the secondary dust removal device 5 to monitor and control the pressure of the pipeline and prevent the backflow of coke powder; a temperature sensor 11 is installed on the inlet pipeline of the boiler 4 and the outlet pipeline of the heat exchanger 8 to monitor the heat exchange efficiency; a material level sensor 10 is installed on the side wall of the ash hopper I3 and the ash hopper II6 to detect the material accumulation in the ash hopper in real time. A PLC controller is used as the main control unit, and the IM153 interface module is used to realize data interaction with each sensor. The PLC controller is electrically connected to the operator station 13, and the operator station 13 is connected to the remote control end and the centralized control center end through independent threads. The operator station 13 realizes remote display and control with the remote control end through the Internet, and the operator station 13 is connected to the centralized control center end through an HDMI cable to realize on-site display and control. To ensure the stability of the control system, various sensors are operated through independent threads, providing redundancy for the control system and ensuring that the system can still operate stably when a single link fails.

[0027] Specifically, Figures 3 to 5 As shown, the temperature sensor 11 is connected to the PLC controller via the interface modules shown by P1 and P2, the pressure sensor 9 is connected to the PLC controller via the interface modules shown by P3 to P6, and the material level sensor 10 is connected to the PLC controller via the interface modules shown by P7 to P11.

[0028] Specifically, the inlet and outlet pipes of the primary dust removal equipment 2 and the secondary dust removal equipment 5 are key points for detecting changes in internal pressure of the system. Monitoring the pressure at these locations can prevent pipe blockage and equipment damage, ensure smooth gas flow, and adjust system parameters to optimize dust removal effect and improve efficiency. The ash hopper is a place for collecting dust and impurities generated during the dust removal process. Monitoring the ash hopper material level is very important for preventing overflow and keeping the system clean. The material level sensor 10 can monitor the material accumulation in the ash hopper I3 and the ash hopper II6. When the material level reaches a certain height, it can cooperate with the discharge mechanism to avoid dust overflow and ensure the normal operation of the dust removal equipment. The temperature on the inlet pipe of the boiler 4 and the outlet pipe of the heat exchanger 8 directly affects the thermal energy conversion efficiency and the thermal balance of the system. By monitoring the temperature at these locations, it is ensured that the boiler 4 and the heat exchanger 8 operate at the optimal temperature, improve the thermal energy utilization efficiency, and prevent equipment damage or reduced efficiency due to excessively high or low temperatures.
