[0003] The process waste gas is transported to the terminal treatment system through the air duct and the exhaust centrifugal fan under positive pressure and then discharged in compliance with the standards. The variable frequency exhaust fan and the pressure sensor of the main pipeline are PID controlled to control the pressure of the main pipeline at a stable pressure value. The process of the organic exhaust terminal treatment system is "zeolite wheel adsorption and desorption + regenerative thermal incinerator (RTO)".

[0028] The present invention provides a switching control system for a main and standby system for process exhaust gas treatment.

[0029] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention. The present invention can be embodied in many different forms and is not limited to the embodiments described herein.

[0030] like Figure 1 A schematic structural diagram of a switching control system of a process exhaust treatment main and standby system in an embodiment of the present invention is shown.

[0031] The system comprises:

[0032] The main system 1, the backup system 2 and the switching control system 3; among them, the main system 1 and the backup system 2 are the terminal treatment systems of the process exhaust system, and their main function is to treat the waste gas and ensure that the waste gas meets the environmental protection standards before being discharged. The two systems use the same process system, that is, the zeolite rotor adsorption and desorption combined with the thermal storage incinerator (RTO) system, and are respectively provided with a rotor inlet valve that can be opened and closed to control the introduction of waste gas. Among them, the zeolite rotor is a highly efficient adsorption device that can adsorb harmful substances in the waste gas. In the adsorption stage, the waste gas passes through the adsorption area of ​​the rotor, and the harmful substances are adsorbed by the zeolite material; in the desorption stage, the rotor is heated with hot air to desorb the adsorbed harmful substances to form concentrated waste gas. The concentrated waste gas enters the RTO for high-temperature incineration to convert the harmful substances into harmless substances. RTO uses thermal storage technology, which can efficiently recover the heat generated during the incineration process and reduce energy consumption.

[0033] The switching control system 3 is communicatively connected with the main system 1 and the backup system 2, and is used to control the main system 1 or the backup system 2 to perform corresponding treatment on the exhaust gas based on the set single system startup control mechanism, the main switching backup control mechanism and the backup switching main control mechanism.

[0034] In one embodiment, the switching control system 3 includes:

[0035] The single system startup control module is used to control the startup of the main system or the backup system to process the exhaust gas accordingly when the single system startup signal is received and the runner inlet valve of the backup system is in an open state when both the main system and the backup system are not in operation and the exhaust gas enters the runner of the backup system for adsorption.

[0036] The main switching standby control module is used when only the main system is running and the main system's runner inlet valve is in an open state, and the exhaust gas enters the main system's runner for adsorption. When the main switching standby signal is received, the main switching standby control mechanism is used to control the main system to switch to the standby system to process the exhaust gas accordingly;

[0037] The standby switching to main control module is used when only the standby system is running and the standby system's rotor inlet valve is in the open state, and the exhaust gas enters the standby system's rotor for adsorption. When the standby switching to main signal is received, the standby switching to main control mechanism is adopted to control the standby system or switch the standby system to the main system to perform corresponding treatment on the exhaust gas.

[0038] In one embodiment, when both the main system and the backup system are normal and not running, a single system startup control mechanism is used to start the main system or the backup system to process the exhaust gas accordingly. Figure 2 , the single system startup control mechanism includes:

[0039] When the backup system start signal is received, the backup system is controlled to start heating, and the backup system automatically runs after the heating is completed; specifically, when the backup system start signal is received, that is, there is a backup system start demand, the switching control system sends an instruction to the backup system to start its heating process, and during the heating process, the rotor inlet valve of the backup system remains open, allowing the exhaust gas to enter the rotor for adsorption. After the heating is completed, the backup system automatically runs and officially starts to treat the exhaust gas.

[0040] When the main system start-up signal is received, the main system is controlled to start heating up. After the heating is completed, the rotor inlet valve of the main system is opened and the rotor inlet valve of the backup system is closed, so that the exhaust gas enters the main system rotor for adsorption, and the main system automatically operates. Specifically, when the main system start-up signal is received, that is, there is an active system startup requirement, the switching control system sends a command to the main system to start its heating process. During the heating process, the rotor inlet valve of the backup system remains in an open state, but the rotor inlet valve of the main system is in a closed state. After the main system is heated up, the rotor inlet valve of the main system is controlled to open, and the rotor inlet valve of the backup system is closed at the same time, so that the exhaust gas enters the main system rotor for adsorption, and the main system automatically operates to officially start treating the exhaust gas.

[0041] It should be noted that the temperature rise of the backup system and the main system can be controlled by automatically controlling the temperature rise by sending a control instruction, or by notifying the staff to manually raise the temperature according to demand, and there is no limitation to this.

[0042] In one embodiment, when only the main system is running, the main system is switched to the backup system by the main system switching control mechanism to process the exhaust gas accordingly. Figure 3 , the active switching standby control mechanism includes:

[0043] When receiving the active switching signal of the backup system, the backup system is controlled to start heating up. After the heating is completed, the rotor inlet valve of the backup system is opened and the rotor inlet valve of the main system is closed, so that the exhaust gas enters the backup system rotor for adsorption, the main system is controlled to shut down, and the backup system automatically runs; specifically, when receiving the active switching signal of the backup system, that is, there is a demand to switch from the active system to the backup system, the switching control system sends an instruction to the backup system to start its heating process. During the heating process, the main system continues to run, and the rotor inlet valve of the main system remains open, allowing the exhaust gas to enter the rotor for adsorption. Once the backup system is heated up, the valve switching operation will be performed, that is, the rotor inlet valve of the backup system is opened and the rotor inlet valve of the main system is closed, so that the exhaust gas enters the backup system rotor for adsorption, and the switching control system sends a shutdown instruction to the main system, the main system stops running for cooling, and the backup system automatically runs at the same time.

[0044] When a shutdown signal due to a main system operation failure is received, the rotor inlet valve of the backup system is opened, and the rotor inlet valve of the main system is closed, so that the exhaust gas enters the backup system rotor for adsorption, and the main system fault control mechanism is used to control the main system or the backup system based on the main system fault degree. Specifically, when a shutdown signal due to a main system operation failure is received, that is, the main system is shut down due to a failure, the rotor inlet valve of the backup system is opened, and the rotor inlet valve of the main system is closed, so that the exhaust gas enters the backup system rotor for adsorption, the central control room receives an alarm signal, and feeds back the main system fault degree to the switching control system, and the switching control system uses the main system fault control mechanism to control the main system or the backup system based on the main system fault degree.

[0045] It should be noted that the control of the standby system heating and the main system shutdown may be automatic control by sending control instructions, or manual control may be performed by notifying staff according to needs, and there is no limitation on this.

[0046] In a specific embodiment, the primary system failure control mechanism includes:

[0047] If the fault level of the main system is a quick repair obstacle, that is, the fault can be repaired in a short time, and there is no need to replace key components or perform large-scale repairs, then when the switching control system receives the main system start signal generated by restarting the main system after repair, it controls the main system to start heating. While the main system is heating up, the backup system is still running, and the runner inlet valve of the backup system is in an open state, and the exhaust gas enters the backup system runner for adsorption. After the heating is completed, the runner inlet valve of the main system is opened and the runner inlet valve of the backup system is closed, so that the exhaust gas enters the main system runner for adsorption, and the main system automatically runs;

[0048] If the main system fault is serious, that is, the fault requires a long time to repair, the backup system is controlled to start heating up. After the heating is completed, the backup system automatically runs and can be restarted after the repair is completed.

[0049] It should be noted that the temperature rise of the backup system and the main system can be controlled by sending a control command to automatically raise the temperature, or by notifying the staff to manually raise the temperature according to demand, and there is no limitation to this.

[0050] In one embodiment, when only the backup system is running, a backup switching control mechanism is used to control the backup system or switch the backup system to the main system to process the exhaust gas accordingly. Figure 4 , the standby switching master control mechanism includes:

[0051] When the active switching signal of the main system is received, the main system is controlled to start heating up. After the heating is completed, the rotor inlet valve of the main system is opened and the rotor inlet valve of the backup system is closed, so that the exhaust gas enters the rotor of the main system for adsorption, the backup system is controlled to shut down, and the main system runs automatically; specifically, when the active switching signal of the main system is received, that is, there is a demand to switch from the backup system to the main system, a start command is sent to the main system to start its heating process. While the main system is heating up, the backup system is still running, the rotor inlet valve of the backup system is in an open state, and the exhaust gas enters the rotor of the backup system for adsorption. After the heating is completed, the valve switching operation is performed, that is, the rotor inlet valve of the main system is opened, and the rotor inlet valve of the backup system is closed at the same time, so that the exhaust gas enters the rotor of the main system for adsorption. After the valve switching is completed, a shutdown command is sent to the backup system, the backup system stops running for cooling, and the main system runs automatically.

[0052] When a standby system operation failure shutdown signal is received, the standby system failure control mechanism is used to control the main system or the standby system based on the standby system failure degree. Specifically, when a standby system operation failure shutdown signal is received, that is, the standby system shuts down due to an operation failure, the central control room receives an alarm signal and feeds back the standby system failure degree to the switching control system, and the switching control system controls the main system or the standby system based on the standby system failure degree using the standby system failure control mechanism.

[0053] It should be noted that the control of the temperature rise of the main system and the shutdown of the backup system can be automatic control by sending control instructions, or manual control can be notified to the staff according to needs, and there is no limitation on this.

[0054] In a specific embodiment, the backup system failure control mechanism includes:

[0055] If the fault level of the backup system is a quick-repair fault, that is, the fault can be repaired in a short time, the switching control system controls the backup system to start heating when receiving a backup system start signal sent by the backup system after the repair and restart, and the backup system automatically runs after the heating is completed;

[0056] If the fault of the backup system is serious, that is, the fault needs a long time to repair, the main system is controlled to start heating up. While the main system is heating up, the backup system is still running, and the rotor inlet valve of the backup system is in the open state, and the exhaust gas enters the rotor of the backup system for adsorption. After the heating is completed, the rotor inlet valve of the main system is opened, and the rotor inlet valve of the backup system is closed at the same time, so that the exhaust gas enters the rotor of the main system for adsorption, and the main system runs automatically; after the repair is completed, it can be restarted.

[0057] If the backup system fault is a fire alarm fault, control the runner inlet valve of the main system and close the runner inlet valve of the backup system at the same time, so that the exhaust gas enters the main system runner for adsorption, control the main system to start heating, and the main system will automatically run after heating is completed. After the fire alarm fault is repaired, it can be restarted.

[0058] It should be noted that the temperature rise of the main system and the standby system can be controlled by sending a control command to automatically raise the temperature, or by notifying the staff to manually raise the temperature according to demand, and there is no limitation to this.

[0059] In one embodiment, the system is further provided with a bypass system, including components such as a bypass pipe and a bypass valve; the bypass system is designed to provide a temporary exhaust gas treatment channel. The bypass system is connected to the switching control system and is used to perform corresponding treatment on the exhaust gas in an emergency, that is, when both the main system and the backup system cannot be used, the switching control system immediately sends a start-up command to the bypass system. After receiving the start-up command, the bypass valve opens quickly, allowing the exhaust gas to be temporarily treated through the bypass pipe. The bypass system provides additional safety for the process exhaust system, ensuring that the exhaust gas can be properly treated even when both the main system and the backup system cannot work normally.

[0060] Similar to the principle of the above embodiment, the present invention provides a switching control method for a main and standby system of process exhaust treatment.
