Description

Technical Field

[0001] This application relates to the field of odor control technology in pulp mills, specifically to an odor control system and method that operates continuously. Background Technology

[0002] The related technology used in the odor control system for pulp mills can successfully collect and chemically convert the malodorous gases generated during the production process of sulfate pulp mills. Since many of the collected pollutants are flammable, combustion is used as the main means of odor treatment. The alkali recovery furnace is the main combustion point, while lime kilns, coal-fired boilers, and odor incinerators are backup combustion points. However, in the event of a sudden power outage, the odor collection and combustion treatment equipment will trip in a chain reaction, and the odor will overflow and spread, causing serious environmental impacts and posing a serious challenge to the sustainable development of enterprises.

[0003] Therefore, how to minimize odor diffusion when a sudden power outage causes an abnormal shutdown has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this application is to provide an uninterrupted odor control system and method to minimize the possibility of odor overflow and diffusion during sudden power outages. The specific solution is as follows:

[0005] An uninterrupted odor control system includes an electrical power supply system, which includes at least one power grid line, an emergency power supply device, a backup generator set, and a centralized power supply bus. All electrical equipment in the odor control system is connected to the centralized power supply bus. The power grid line and the backup generator set are electrically connected through the emergency power supply device and the centralized power supply bus.

[0006] When at least one of the power grid supply lines is operating normally, the emergency power supply device is in float charging mode, and the backup generator set is in standby mode. When all the power grid supply lines are faulty, the emergency power supply device supplies power to the electrical equipment in the odor control system and the backup generator set, causing the backup generator set to start. When the backup generator set is supplying power to the electrical equipment in the odor control system, the emergency power supply device switches to float charging mode.

[0007] Optionally, the power grid supply line includes a main power supply line and at least one backup power supply line, which are electrically connected to the centralized power supply bus. In the event of a failure of the main power supply line, one of the backup power supply lines supplies power to the electrical equipment in the odor control system.

[0008] Optionally, the odor control system further includes an odor incinerator and an odor collection system, as well as a water supply subsystem for providing cooling water to the odor incinerator and the odor collection system. The water supply subsystem includes a backup cooling water source, a dedicated cooling water pipeline, and a backup cooling water pump. The backup cooling water source is connected to the cooling flow channel of the equipment to be cooled in the odor control system through the dedicated cooling water pipeline, and the backup cooling water pump is installed on the dedicated cooling water pipeline.

[0009] Optionally, the odor control system further includes an odor incinerator, and the backup cooling water source is located near the odor incinerator.

[0010] Optionally, the odor incinerator and the odor collection system include a cooling water pump, and the odor treatment system further includes a sealing water supply subsystem. The sealing water supply subsystem includes a backup sealing water source, a dedicated sealing water pipeline, and a backup sealing water pump. The backup sealing water source is connected to the sealing water pipeline of the cooling water pump through the dedicated sealing water pipeline, and the backup sealing water pump is installed on the dedicated sealing water pipeline.

[0011] Optionally, the odor control system further includes a steam supply subsystem, which includes at least one steam source, at least one steam supply pipeline, and at least one steam storage device. The steam source is connected to the steam-using equipment in the odor control system through the corresponding steam supply pipeline. The steam storage device is installed on at least one steam supply pipeline and is configured to store steam when the steam source is supplying steam normally and to supply steam to the steam-using equipment in the odor control system when all steam sources are faulty.

[0012] Optionally, the odor control system further includes an odor incinerator, the steam source near the odor incinerator is a main steam source, the steam supply pipeline connecting the main steam source and the steam-using equipment in the odor control system is a main steam pipeline, and the steam storage device is installed on the main steam pipeline.

[0013] Optionally, the odor control system further includes a compressed air supply subsystem, which includes at least one compressed air source, an air storage tank, a compressed air supply pipeline, and a backup air compressor. The air storage tank is connected to the air-using equipment in the odor control system through the compressed air supply pipeline, and both the compressed air source and the backup air compressor are connected to the air storage tank.

[0014] A method for uninterrupted operation of an odor control system, applicable to the aforementioned uninterrupted operation odor control system, includes the following steps to achieve uninterrupted power supply:

[0015] When the power grid supply lines are operating normally, the emergency power supply device is in float charging mode, and the backup generator is in standby mode. When all power grid supply lines are faulty, the emergency power supply device supplies power to the electrical equipment in the odor control system and the backup generator, causing the backup generator to start. When the backup generator is supplying power to the electrical equipment in the odor control system, the emergency power supply device switches to float charging mode.

[0016] Optionally, the power grid supply line includes a main power supply line electrically connected to the centralized power supply bus and at least one backup power supply line. To achieve uninterrupted power supply, the following steps are also included:

[0017] In the event of a failure in the main power supply line, one of the backup power supply lines supplies power to the electrical equipment in the odor control system.

[0018] Optionally, achieving uninterrupted cooling water supply to the odor incinerator includes the following steps:

[0019] In the event of a failure in the main cooling water system, the backup cooling water pump starts, driving the backup cooling water source to deliver cooling water to the cooling channel of the odor incinerator through a dedicated cooling water pipeline.

[0020] The cooling water supply for an uninterrupted odor collection system includes the following steps:

[0021] In the event of a failure in the main cooling water system, the backup cooling water pump is activated, driving the backup cooling water source to deliver cooling water to the cooling channel of the odor collection system through the dedicated cooling water pipeline.

[0022] Optionally, achieving uninterrupted cooling water pump seal water supply also includes the following steps:

[0023] In the event of a failure in the main sealing water system, the backup sealing water pump starts, driving the backup sealing water source to deliver sealing water to the sealing water pipeline of the cooling water pump through a dedicated sealing water pipeline.

[0024] Optionally, achieving uninterrupted steam supply includes the following steps:

[0025] Under normal steam supply conditions, the steam storage device stores steam.

[0026] In the event of a steam source failure, the steam storage device supplies steam to the steam-using equipment in the odor control system until the steam source resumes operation.

[0027] Optionally, achieving uninterrupted compressed air supply includes the following steps:

[0028] The air tank stores compressed air when at least one compressed air source is supplying compressed air normally.

[0029] In the event of a compressed air source failure, the air storage tank supplies compressed air to the air-consuming equipment in the odor control system and starts the backup air compressor.

[0030] When the standby air compressor is supplying compressed air normally, the air tank stores compressed air.

[0031] This application establishes a power supply system, which includes at least one mains power line, an emergency power supply device, a backup generator set, and a centralized power supply bus. The electrical equipment in the odor control system uses a centralized power supply method. The mains power line, emergency power supply device, and backup generator set can all supply power to the equipment in the odor control system. In the event of a power outage (such as a sudden power failure), the emergency power supply device can immediately provide emergency power to the equipment in the odor control system. Simultaneously, the emergency power supply device can provide the necessary buffer time for the rapid startup of the backup generator set. Once the backup generator set has stably supplied power to the equipment in the odor control system, the emergency power supply device switches back to float charging mode. This achieves a smooth power supply switch, ensuring uninterrupted operation of the odor collection and treatment system, minimizing the possibility of a sudden power outage causing the odor collection and treatment system to shut down and leading to the overflow and diffusion of malodorous gases, and reducing environmental impact.

[0048] Please refer to Figure 1 , Figure 1 A schematic diagram of the electronic system for the uninterrupted operation odor control system provided in this application.

[0049] This application provides an uninterrupted odor control system, including an electronic power supply system 100. The electronic power supply system 100 includes at least one power grid line 101, an emergency power supply device 102, a backup generator set 103, and a centralized power supply bus 104. All electrical equipment 001 in the odor control system is connected to the centralized power supply bus 104. The power grid line 101 and the backup generator set 103 are electrically connected through the emergency power supply device 102 and the centralized power supply bus 104.

[0050] When at least one power grid line 101 is supplying power normally, the emergency power supply device 102 is in a float charging state, and the standby generator set 103 is in a standby state. When all power grid lines 101 are faulty, the emergency power supply device 102 supplies power to the electrical equipment 001 and the standby generator set 103 in the odor control system, causing the standby generator set 103 to start. When the standby generator set 103 is supplying power to the electrical equipment 001 in the odor control system, the emergency power supply device 102 switches to a float charging state.

[0051] The odor control system described in this application embodiment operates continuously and includes a power supply system 100. The power supply system 100 includes at least one mains power line 101, an emergency power supply device 102, a backup generator set 103, and a centralized power supply bus 104. The electrical equipment 001 in the odor control system uses a centralized power supply method, and the mains power line 101, the emergency power supply device 102, and the backup generator set 103 can all supply power to the electrical equipment 001 in the odor control system. In the event of a power grid failure (such as a sudden power outage), the emergency power supply device 102 can immediately provide emergency power to the electrical equipment 001 in the odor control system. At the same time, the emergency power supply device 102 can also provide the necessary buffer time for the rapid start-up of the backup generator set 103. After the backup generator set 103 stably supplies power to the electrical equipment 001 in the odor control system, the emergency power supply device 102 switches back to float charging mode. This achieves a smooth switching of power supply, ensuring that the odor collection and treatment system does not stop operating, minimizing the possibility of the odor collection and treatment system shutting down due to a sudden power outage and causing the overflow and diffusion of malodorous gases, and reducing environmental impact.

[0052] In some embodiments, the emergency power supply device 102 may use an industrial-grade UPS (Uninterruptible Power Supply) battery pack, which can quickly take over the power supply when the power grid line 101 suddenly fails, minimizing the risk of downtime that may be caused by power outage.

[0053] In some embodiments, the backup generator set 103 may be a diesel generator set, which can quickly start up and reach the power supply state with the support of the emergency power supply device 102, and take over the emergency power supply device 102 to provide continuous and stable power to the electrical equipment 001, so as to minimize the risk of downtime caused by power outage.

[0054] like Figure 1 As shown in the embodiments of this application, the electrical equipment 001 in the odor control system is located in two areas. Therefore, this application provides two emergency power supply devices 102. Each electrical equipment 001 in the same area is connected to one emergency power supply device 102. The emergency power supply device 102 is positioned close to the corresponding electrical equipment 001, which helps to shorten the cable laying length and reduce costs. In other embodiments of this application, it is also feasible to connect the same emergency power supply device 102 to both electrical equipment 001 in both areas.

[0055] Please continue to refer to this. Figure 1In this embodiment of the application, the power grid power supply line 101 includes a main power supply line 101-1 and at least one backup power supply line 101-2 that are electrically connected to the centralized power supply bus 104 respectively. In the case of a failure of the main power supply line 101-1, one of the backup power supply lines 101-2 supplies power to the electrical equipment 001 in the odor control system.

[0056] As configured above, in this embodiment, the power grid supply line 101 adopts a design where the main power supply line 101-1 and the backup power supply line 101-2 are mutually redundant across plant areas. For example, if both the first plant area and the second plant area need to perform odor control, for the odor control system of the first plant area, the power grid supply line 101 of the first plant area is the main power supply line 101-1, and the power grid supply line 101 of the second plant area is the backup power supply line 101-2. In the event of a failure in the power grid supply line 101 of the first plant area, the power grid supply line 101 of the second plant area can be quickly switched over. The system can switch and continuously supply power to the electrical equipment 001 of the odor control system. For the odor control system in the second plant area, the power grid power supply line 101 in the second plant area is the main power supply line 101-1, and the power grid power supply line 101 in the first plant area is the backup power supply line 101-2. In the event of a failure of the power grid power supply line 101 in the second plant area, the power grid power supply line 101 in the first plant area can quickly switch and continuously supply power to the electrical equipment 001 of the odor control system. This achieves cross-plant area power allocation and minimizes the risk of downtime caused by power outages.

[0057] Please refer to Figures 2-3 , Figure 2 A schematic diagram of the first part of the water supply subsystem for cooling the odor incinerator in the uninterrupted odor control system provided in this application; Figure 3 This is a schematic diagram of the second part of the cooling water supply subsystem of the odor collection system in the uninterrupted odor control system provided in this application.

[0058] The odor control system of this application embodiment also includes an odor incinerator and an odor collection system, as well as a water supply subsystem 200 for providing cooling water to the odor incinerator and the odor collection system. The water supply subsystem 200 includes a backup cooling water source 201, a dedicated cooling water pipeline 202 and a backup cooling water pump 203. The backup cooling water source 201 is connected to the cooling flow channel of the equipment 002 to be cooled in the odor control system through the dedicated cooling water pipeline 202, and the backup cooling water pump 203 is installed on the dedicated cooling water pipeline 202.

[0059] Typically, the water supply subsystem 200 also includes a main cooling water source, a main cooling water pipeline, and a main water pump. The main water pump is located on the main cooling water pipeline. The main cooling water source is connected not only to the cooling channel of the equipment 002 to be cooled in the odor control system, but also generally to the cooling channels of other systems within the plant area. The dedicated cooling water pipeline 202, as mentioned above, is only connected to the cooling channel of the equipment 002 to be cooled in the odor control system. Thus, when the main cooling system experiences a water supply interruption due to a malfunction, the backup cooling water pump 203 can quickly start, driving the backup cooling water source 201 to deliver cooling water to the equipment 002 to be cooled in the odor control system through the dedicated cooling water pipeline 202. This ensures uninterrupted cooling water supply, guaranteeing that the equipment 002 to be cooled in the odor control system has sufficient cooling water for cooling and thus ensuring the normal operation of both the equipment 002 and the odor control system.

[0060] Since the dedicated cooling water pipeline 202 is only connected to the cooling flow channel of the equipment 002 to be cooled in the odor control system, the diameter of the dedicated cooling water pipeline 202 is significantly smaller than that of the main cooling water pipeline, which can increase the flow rate of the cooling water and minimize the occurrence of cooling interruptions.

[0061] Furthermore, in this embodiment of the application, the odor control system also includes an odor incinerator, and a backup cooling water source 201 is located near the odor incinerator.

[0062] As the core equipment for odor combustion treatment, the odor incinerator has surrounding equipment that needs to be cooled, which are mostly key components operating under high-temperature conditions. The backup cooling water source 201 is located close to the odor incinerator, which can significantly shorten the laying length of the dedicated cooling water pipeline 202 and ensure that the cooling water can maintain a stable flow rate when it reaches the equipment to be cooled 002, thus ensuring cooling efficiency. At the same time, it can also reduce costs and improve the economics of the odor treatment system of this application.

[0063] The backup cooling water source 201 can be a cooling water tower located near the odor incinerator.

[0064] Please refer to Figure 4 , Figure 4 This is a schematic diagram of the third part of the water pump sealing water supply subsystem in the uninterrupted odor control system provided in this application.

[0065] In this embodiment, the odor incinerator and odor collection system include a cooling water pump 003, and the odor treatment system also includes a sealing water supply subsystem. The sealing water supply subsystem includes a backup sealing water source 204, a dedicated sealing water pipeline 205, and a backup sealing water pump 206. The backup sealing water source 204 is connected to the sealing water pipeline of the cooling water pump 003 through the dedicated sealing water pipeline 205, and the backup sealing water source 204 is installed on the dedicated sealing water pipeline 205.

[0066] Typically, the sealing water supply subsystem also includes a main sealing water source, a main sealing water pipeline, and a main sealing water pump. The main sealing water pump is located on the main sealing water pipeline. The main sealing water source is connected not only to the sealing water pipeline inlet of the cooling water pump 003 in the odor control system, but also generally to the sealing water pipeline inlets of other pumps within the plant area. The dedicated sealing water pipeline 205, as mentioned above, is only connected to the sealing water pipeline inlet of the cooling water pump 003 in the odor control system. Thus, when the main sealing water system malfunctions and the sealing water supply to the pump is interrupted, the standby sealing water pump 206 can quickly start, driving the standby sealing water source 204 to supply sealing water only to the sealing water pipeline of the cooling water pump 003 in the odor control system through the dedicated sealing water pipeline 205. This ensures uninterrupted sealing water supply, guarantees the reliable sealing of the cooling water pump 003 in the odor control system, ensures the normal operation of the odor incinerator and odor collection system in the odor control system, and thus maintains the continuous and stable operation of the odor control system.

[0067] Since the dedicated sealing water pipeline 205 is only connected to the sealing water pipeline of the cooling water pump 003 in the odor control system, the diameter of the dedicated sealing water pipeline 205 is significantly smaller than that of the main sealing water pipeline, which can increase the flow rate of the sealing water and minimize the occurrence of intermittent sealing water supply.

[0068] Please refer to Figure 5 , Figure 5 This is a schematic diagram of the steam supply subsystem in the uninterrupted odor control system provided in this application.

[0069] The odor control system in this embodiment of the application further includes a steam supply subsystem 300. The steam supply subsystem 300 includes at least one steam source 301, at least one steam supply pipeline 302, and at least one steam storage device 303. The steam source 301 is connected to the steam-using equipment 004 in the odor control system through the corresponding steam supply pipeline 302. The steam storage device 303 is installed on at least one steam supply pipeline 302. The steam storage device 303 is configured to store steam when the steam source 301 is supplying steam normally, and to supply steam to the steam-using equipment 004 in the odor control system when the steam source 301 is malfunctioning.

[0070] As configured above, the odor control system in this embodiment of the application includes a steam supply subsystem 300. Under normal steam supply conditions from the steam source 301, the steam storage device 303 can store steam and maintain a stable pressure state to ensure sufficient steam reserves. In case of a failure of the steam source 301, backup steam can be quickly supplied to the steam-using equipment 004 in the odor control system through the steam supply pipeline 302 until the steam source 301 resumes steam supply, thereby achieving uninterrupted steam supply. This minimizes the risk of the steam-using equipment 004 shutting down or ceasing operation due to steam interruption, ensuring the continuity of operation of the steam-using equipment 004 and the stable operation of the odor control system.

[0071] When the steam source 301 is supplying steam normally, the steam storage device 303 should maintain a high liquid level and pressure level to ensure sufficient steam supply time in emergencies. For example, in some embodiments, the pressure of the steam storage device 303 is ≥0.8MPa.

[0072] like Figure 5 As shown, in some embodiments of this application, the steam storage device 303 uses a steam accumulator to efficiently store steam and maintain a stable pressure state, avoiding the impact of steam supply fluctuations from the steam source 301 on the steam-using equipment 004. When the steam source 301 fails, the steam accumulator can respond quickly to avoid steam supply interruption.

[0073] Please continue to refer to this. Figure 5 In this embodiment of the application, there are two steam sources 301. The steam source 301 closer to the odor incinerator is the main steam source 301-1, and the steam source 301 farther away from the odor incinerator is the backup steam source 301-2. In the case of failure of the main steam source 301-1, the backup steam source 301-2 supplies steam to the steam-using equipment 004 in the odor treatment system.

[0074] The steam supply pipeline 302, which connects the main steam source 301-1 and the steam-using equipment 004 in the odor control system, is defined as the main steam pipeline 302-1, and the steam storage device 303 is installed on the main steam pipeline 302-1.

[0075] Thus, the steam storage device 303 is located close to the odor incinerator, which helps to shorten the steam transport path, reduce the pressure loss of steam during the transport process, and ensure that the steam maintains a stable pressure when it reaches the steam-using equipment 004.

[0076] Depend on Figure 5 As can be seen, in this embodiment of the application, the steam source 301 includes a medium-pressure steam distribution cylinder 301a, and the steam storage device 303 is installed on the steam supply pipeline 302 that connects the medium-pressure steam distribution cylinder 301a and the steam-using equipment 004, so that the steam inside the steam storage device 303 has a large pressure and can maintain the steam supply for a longer time.

[0077] Please refer to Figure 6 , Figure 6 This is a schematic diagram of the compressed air supply subsystem in the uninterrupted odor control system provided in this application.

[0078] The odor control system in this embodiment of the application also includes a compressed air supply subsystem 400. The compressed air supply subsystem 400 includes at least one compressed air source 401, an air storage tank 402, a compressed air supply pipeline 403, and a backup air compressor 404. The air storage tank 402 is connected to the air-using equipment 005 in the odor control system through the compressed air supply pipeline 403. The compressed air source 401 and the backup air compressor 404 are both connected to the air storage tank 402.

[0079] As configured above, the odor control system in this embodiment of the application includes a compressed air supply subsystem 400. When the compressed air source 401 is supplying compressed air normally, the air storage tank 402 stores surplus compressed air to ensure sufficient compressed air reserves in case the compressed air source 401 fails. During the startup phase of the standby air compressor 404, sufficient compressed air can be supplied to the air-using equipment 005 in the odor control system through the compressed air supply pipeline 403 until the standby air compressor 404 is operating stably and can supply compressed air to the air-using equipment 005 normally, thereby achieving uninterrupted compressed air supply and minimizing the risk of the air-using equipment 005 stopping or ceasing operation due to air supply interruption, ensuring the continuity of operation of the air-using equipment 005 and the stable operation of the odor control system.

[0080] Depend on Figure 6 It can be seen that the compressed air supply subsystem 400 is equipped with multiple pneumatic switching valves 405. When the compressed air source 401 fails, the pressure interlock is triggered to realize the automatic opening and closing of the pneumatic switching valves 405, thereby preventing the compressed air supply pipeline 403 of this odor treatment system from depressurizing rapidly and ensuring that the relevant air-using equipment 005 of the odor treatment system has sufficient compressed air to achieve stable operation.

[0081] For example, a first pneumatic switch valve 405-1 is provided between the compressed air source 401 and the air storage tank 402. When the compressed air source 401 is operating normally, the first pneumatic switch valve 405-1 is opened, so that the compressed air source 401 can supply compressed air to the air-using equipment 005 normally; when the compressed air source 401 fails, the first pneumatic switch valve 405-1 is automatically closed.

[0082] Since the compressed air source 401 not only provides compressed air to the relevant air-using equipment 005 of the odor control system, but also to the air-using equipment 005 of other systems, when the compressed air source 401 fails, the first pneumatic switch valve 405-1 automatically closes, which can prevent the compressed air inside the air tank 402 or the compressed air supplied by the backup air compressor 404 from being transferred elsewhere, ensuring that the relevant air-using equipment 005 of the odor control system has sufficient compressed air to achieve stable operation.

[0083] Please continue to refer to this. Figure 6 In this embodiment, multiple air storage tanks 402 are arranged according to the distribution of the air-consuming devices 005. For example, air-consuming devices 005 that are close to each other and located in the same area are connected to one air storage tank 402. In this way, the compressed air delivery path can be shortened, and when the compressed air source 401 fails, compressed air can be supplied to the corresponding air-consuming devices 005 in the fastest speed, avoiding air supply interruption. The air storage capacity of the air storage tank 402 can be adaptively adjusted according to the air consumption of the corresponding air-consuming devices 005.

[0084] This application also provides a method for uninterrupted operation of an odor control system, applicable to the aforementioned uninterrupted operation odor control system, and the method for achieving uninterrupted power supply includes the following steps:

[0085] When at least one power grid line 101 is supplying power normally, the emergency power supply device 102 is in a float charging state, and the standby generator set 103 is in a standby state. When all power grid lines 101 are faulty, the emergency power supply device 102 supplies power to the electrical equipment 001 and the standby generator set 103 in the odor control system, causing the standby generator set 103 to start. When the standby generator set 103 is supplying power to the electrical equipment 001 in the odor control system, the emergency power supply device 102 switches to a float charging state.

[0086] The uninterrupted operation method of the odor control system in this application embodiment allows the power grid line 101, emergency power supply device 102, and standby generator set 103 to all provide power to the electrical equipment 001 in the odor control system. In the event of a power grid line 101 failure (such as a sudden power outage), the emergency power supply device 102 can immediately provide emergency power to the electrical equipment 001 in the odor control system. Simultaneously, the emergency power supply device 102 can also provide stable and uninterrupted power to the standby generator set 103, enabling the standby generator set 103 to start quickly. Once the standby generator set 103 stably supplies power to the electrical equipment 001 in the odor control system, the emergency power supply device 102 switches back to float charging mode. This achieves a smooth switching of power supply, ensuring uninterrupted operation of the odor collection and treatment system, minimizing the possibility of a sudden power outage causing the odor collection and treatment system to shut down and resulting in the overflow and diffusion of malodorous gases, and reducing environmental impact.

[0087] In some embodiments of this application, the power grid supply line 101 includes a main power supply line 101-1 and at least one backup power supply line 101-2, both electrically connected to the centralized power supply bus 104. To achieve uninterrupted power supply, the following steps are also included:

[0088] In the event of a fault in the main power supply line 101-1, one of the backup power supply lines 101-2 supplies power to the electrical equipment 001 in the odor control system.

[0089] As set up above, the power grid power supply line 101 adopts a design of mutual backup between the main power supply line 101-1 and the backup power supply line 101-2 across the plant area. In the event of a failure of the main power supply line 101-1, the backup power supply line 101-2 can quickly switch and continuously supply power to the electrical equipment 001 of the odor treatment system. This realizes the allocation of power across the plant area and minimizes the risk of shutdown that may be caused by power outage.

[0090] In the uninterrupted operation method of the odor control system in this application embodiment, the uninterrupted cooling water supply to the odor incinerator includes the following steps:

[0091] In the event of a failure of the main cooling water source, the standby cooling water pump 203 is started, driving the standby cooling water pump 203 to deliver cooling water to the cooling channel of the odor incinerator through the dedicated cooling water pipeline 202.

[0092] The cooling water supply for an uninterrupted odor collection system includes the following steps:

[0093] In the event of a failure of the main cooling water source, the standby cooling water pump 203 starts, driving the standby cooling water pump 203 to deliver cooling water to the cooling channel of the odor collection system through the dedicated cooling water pipeline 202.

[0094] This ensures an uninterrupted supply of cooling water, guaranteeing that the equipment 002 to be cooled in the odor incinerator and odor collection system has sufficient cooling water for cooling and temperature reduction, thereby ensuring the normal operation of the odor incinerator and odor collection system.

[0095] Since the dedicated cooling water pipeline 202 is only connected to the cooling flow channel of the equipment 002 to be cooled in the odor incinerator and odor collection system, the diameter of the dedicated cooling water pipeline 202 is significantly smaller than that of the main cooling water pipeline, which can increase the flow rate of cooling water and avoid cooling interruptions as much as possible.

[0096] In the uninterrupted operation method of the odor control system in this application embodiment, the uninterrupted supply of sealing water to the cooling water pump 003 further includes the following steps:

[0097] In the event of a failure in the main sealing water system, the standby sealing water pump 206 starts, driving the standby sealing water source 204 to deliver sealing water to the sealing water pipeline of the cooling water pump 003 through the dedicated sealing water pipeline 205.

[0098] In this way, an uninterrupted supply of sealed water is achieved, ensuring the reliable sealing of the cooling water pump 003, guaranteeing the normal operation of the odor incinerator and odor collection system in the odor control system, and thus maintaining the continuous and stable operation of the odor control system.

[0099] Since the dedicated sealing water pipeline 205 is only connected to the sealing water pipeline of the cooling water pump 003 in the odor incinerator and odor collection system, the diameter of the dedicated sealing water pipeline 205 is significantly smaller than that of the main sealing water pipeline, which can increase the flow rate of the sealing water and minimize the occurrence of intermittent sealing water supply.

[0100] In the uninterrupted operation method of the odor control system in this application embodiment, achieving uninterrupted steam supply includes the following steps:

[0101] Under normal steam supply conditions from steam source 301, steam storage device 303 stores steam;

[0102] In the event of a malfunction of the steam source 301, the steam storage device 303 supplies steam to the steam-using equipment 004 in the odor control system until the steam source 301 resumes steam supply.

[0103] In this way, an uninterrupted steam supply can be achieved, minimizing the need for steam-using equipment 004 to shut down or cease operation due to steam interruption, ensuring the continuity of operation of steam-using equipment 004, and guaranteeing the stable operation of the odor control system.

[0104] When the steam source 301 is supplying steam normally, the steam storage device 303 should maintain a high liquid level and pressure level to ensure sufficient steam supply time in emergencies. For example, in some embodiments, the pressure of the steam storage device 303 is ≥0.8MPa.

[0105] In the uninterrupted operation method of the odor control system in this application embodiment, achieving uninterrupted compressed air supply includes the following steps:

[0106] Under the condition that at least one compressed air source 401 is supplying compressed air normally, the air tank 402 stores compressed air;

[0107] In the event that all compressed air sources 401 are malfunctioning, the air storage tank 402 supplies compressed air to the air-consuming equipment 005 in the odor control system and starts the backup air compressor 404.

[0108] When the standby air compressor 404 is supplying compressed air normally, the air tank 402 stores compressed air.

[0109] As configured above, when the compressed air source 401 is supplying compressed air normally, the air storage tank 402 stores surplus compressed air to ensure sufficient compressed air reserves in case the compressed air source 401 fails. During the startup phase of the standby air compressor 404, sufficient compressed air can be supplied to the air-consuming equipment 005 in the odor control system through the compressed air supply pipeline 403 until the standby air compressor 404 is operating stably and can supply compressed air to the air-consuming equipment 005 normally, achieving uninterrupted compressed air supply. This minimizes the risk of the air-consuming equipment 005 stopping or ceasing operation due to air supply interruption, ensuring the continuity of operation of the air-consuming equipment 005 and the stable operation of the odor control system.

[0110] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
