Description

Technical Field

[0001] This utility model relates to the field of cement kiln co-processing of waste technology, and in particular to a carbon dioxide fire extinguishing system applied to the feeding device of a hazardous waste incinerator. Background Technology

[0002] In related technical fields, existing carbon dioxide fire extinguishing technology detects fires using carbon monoxide and temperature sensors, and utilizes sodium bicarbonate to generate carbon dioxide for extinguishing. However, this introduces sodium ions into the cement kiln system during the extinguishing process. Furthermore, using carbon monoxide and temperature sensors for detection is problematic because flammable materials do not produce carbon monoxide when burning under sufficient oxygen conditions. Temperature sensors also have limited detection ranges, making them difficult to detect in situations of complete combustion and localized temperature increases, thus limiting their application scenarios. Utility Model Content

[0003] This invention provides a carbon dioxide fire extinguishing system for use in the feeding device of a hazardous waste incinerator. It addresses the shortcomings of existing technologies that use carbon monoxide and temperature sensors to detect complete combustion and local temperature rise. The system enables real-time monitoring of the material transportation process and timely fire extinguishing when flames form, preventing excessive fire extinguishing that would result in a low temperature of the material entering the incinerator, which would be detrimental to combustion within the incinerator.

[0032] The following is combined with Figure 1 The present invention provides a detailed description of the carbon dioxide fire extinguishing system for a hazardous waste incinerator feeding device through specific embodiments and application scenarios.

[0033] In the embodiments of this utility model, such as Figure 1 As shown, the carbon dioxide fire extinguishing system 10 applied to the feeding device of a hazardous waste incinerator includes a feeding device 100, a photoelectric detection module 200, and a carbon dioxide fire extinguishing unit 300. The photoelectric detection module 200 is located on both sides of the feeding device 100 extending along the transport direction. The photoelectric detection module 200 is used to monitor the location of flames formed by the materials transported on the feeding device 100 in real time. The carbon dioxide fire extinguishing unit 300 is located on both sides of the feeding device 100 extending along the transport direction. The carbon dioxide fire extinguishing unit 300 is communicatively connected to the photoelectric detection module 200. The carbon dioxide fire extinguishing unit 300 is used to extinguish the flames detected in real time by the photoelectric detection module 200.

[0034] The feeding device 100 is responsible for safely and stably conveying the material to be processed into the incinerator 30. The incinerator 30 incinerates the material, and the heat generated is supplied to the cement kiln system 20. The feeding device 100 provides an installation platform for the photoelectric detection module 200 and the carbon dioxide fire extinguishing unit 300, ensuring that these components can effectively cover the entire material conveying path. Of course, in other embodiments, the photoelectric detection module 200 and the carbon dioxide fire extinguishing unit 300 can also be installed using separately provided brackets, etc., and are not specifically limited here.

[0035] The photoelectric detection module 200 is located on both sides of the feeding device 100 extending along the transport direction, ensuring full coverage of the material transport process.

[0036] The photoelectric detection module 200 employs infrared and ultraviolet composite detection technology to perform comprehensive real-time monitoring of the materials transported on the feeding device 100, quickly capturing the location of flame formation. Once the characteristic flame spectrum is detected, the photoelectric detection module 200 immediately generates an electrical signal and transmits it to the carbon dioxide fire extinguishing unit 300, triggering timely fire extinguishing operations. Thus, by providing precise flame location information, the photoelectric detection module 200 ensures that fires are detected in their early stages and effectively controlled, preventing the fire from spreading or causing greater damage.

[0037] The carbon dioxide fire extinguishing unit 300 is also located on both sides of the feeding device 100 extending along the transport direction, corresponding to the photoelectric detection module 200, to ensure accurate coverage of the flame location.

[0038] The carbon dioxide fire extinguishing unit 300 is connected to the photoelectric detection module 200 via communication, receiving flame location information from the detector 220 and initiating the spraying procedure accordingly. Based on the received signal, the carbon dioxide fire extinguishing unit 300 can accurately spray liquid carbon dioxide to the location of the flame, achieving precise fire extinguishing and reducing unnecessary cooling effects. Some designs also allow the nozzle 320 angle to automatically adjust according to the speed of the conveying equipment, ensuring precise coverage of the flame area even during material movement.

[0039] The carbon dioxide fire extinguishing unit 300 ensures the effectiveness and targeting of the fire extinguishing operation through precise spray control, avoiding the problem of excessively low material temperature caused by over-extinguishing, and ensuring that the material entering the incinerator 30 can participate in combustion in a suitable state.

[0040] This application incorporates a photoelectric detection module 200 and a carbon dioxide fire extinguishing unit 300 along the transport direction in the feeding device 100. The photoelectric detection module 200 provides comprehensive real-time monitoring of the material. If a flame forms during transport, the module immediately detects its location, ensuring a rapid response from the moment the flame forms. The carbon dioxide fire extinguishing unit 300 communicates with the photoelectric detection module 200, enabling precise fire extinguishing based on the flame location information provided by the module. This avoids unnecessary extinguishing operations and ensures that carbon dioxide is only sprayed at the location of the flame, reducing the negative impact on the material temperature. By precisely controlling the carbon dioxide injection, this fire extinguishing system effectively extinguishes the flame while avoiding over-extinguishing. This prevents a drop in material temperature due to over-extinguishing, ensuring the material maintains a suitable temperature upon entering the incinerator 30, which is beneficial for complete combustion within the incinerator 30. Furthermore, because the temperature of the material entering the incinerator 30 is effectively controlled, the combustion efficiency within the incinerator 30 is optimized, which helps to improve the processing capacity of the incinerator 30 and the completeness of waste combustion, reduces the emission of harmful substances, and improves the resource recovery rate.

[0041] Reference Figure 1 According to the present invention, a carbon dioxide fire extinguishing system 10 applied to a hazardous waste incinerator feeding device is provided. The carbon dioxide fire extinguishing unit 300 includes a carbon dioxide storage tank 310, a nozzle 320, an injector 330, and a pipeline 340. The nozzle 320 is arranged to spray towards the loading surface of the feeding device 100. The injector 330 is connected to the nozzle 320. The injector 330 is connected to the carbon dioxide storage tank 310 through the pipeline 340. The injector 330 is communicatively connected to the photoelectric detection module 200.

[0042] Understandably, as a storage container for liquid carbon dioxide, the carbon dioxide storage tank 310 provides the necessary extinguishing medium for the entire fire extinguishing system, ensuring that the system can quickly obtain sufficient carbon dioxide for fire extinguishing operations when needed.

[0043] The nozzle 320 is positioned to spray towards the loading surface of the feeding device 100, ensuring that carbon dioxide can directly cover the flame area for precise fire suppression. The design and layout of the nozzle 320 determine the direction and range of carbon dioxide injection, ensuring that the extinguishing medium accurately reaches the target location, quickly suppresses the flame, and avoids affecting surrounding unburned materials.

[0044] The injector 330 is connected to the nozzle 320 and communicates with the carbon dioxide storage tank 310 via pipeline 340. The injector 330 also communicates with the photoelectric detection module 200, receiving flame location information from the detector 220 and initiating the spraying procedure accordingly. The injector 330 analyzes the electrical signals transmitted from the photoelectric detection module 200 to determine the specific location and intensity of the flame. Based on the received information, the injector 330 precisely controls the amount and direction of carbon dioxide spray, ensuring the effectiveness and targeting of the fire extinguishing operation. Some design features allow the injector 330 to automatically adjust the nozzle 320 angle according to the speed of the conveying equipment, ensuring precise coverage of the flame area even during material movement.

[0045] Pipeline 340 connects injector 330 to carbon dioxide storage tank 310, ensuring that carbon dioxide can be smoothly delivered to nozzle 320 for injection when needed.

[0046] Reference Figure 1 According to the present invention, a carbon dioxide fire extinguishing system 10 applied to a feeding device of a hazardous waste incinerator is provided. The carbon dioxide fire extinguishing unit 300 includes multiple nozzles 320, which are respectively disposed on both sides of the feeding device 100 extending along the transport direction, and the multiple nozzles 320 are respectively connected to the injector 330.

[0047] Understandably, by installing multiple nozzles 320 on both sides of the feeding device 100, comprehensive coverage of the entire material conveying channel can be achieved, ensuring that the flames can be quickly extinguished regardless of their location. Multiple nozzles 320 can simultaneously spray carbon dioxide from different angles, forming multi-point fire suppression, improving fire extinguishing efficiency, and reducing the possibility of flame reignition.

[0048] Each nozzle 320 is individually connected to the injector 330, meaning that the spray of each nozzle 320 can be controlled independently, adjusting the spray intensity and range according to the specific location and size of the flame. The independently connected nozzles 320 can target specific areas of the flame for precise extinguishing without affecting other non-flame areas, thus improving the system's flexibility and response speed.

[0049] In one embodiment, the nozzle 320 is rotatably disposed on both sides of the feeding device 100 extending in the transport direction.

[0050] Understandably, the rotatable nozzle 320 can adjust its spray angle according to the specific location and spread direction of the flame, thereby more accurately targeting the flame for fire extinguishing. Simultaneously, by rotating the nozzle 320, the coverage area of ​​a single nozzle 320 can be expanded without increasing the number of nozzles, thus improving fire extinguishing efficiency. Furthermore, since the material shape and stacking method of the hazardous waste incinerator 30 feeding device 100 may vary, the rotatable nozzle 320 can adapt to different material forms and flame positions, improving the adaptability of the fire extinguishing system.

[0051] Reference Figure 1 According to the present invention, a carbon dioxide fire extinguishing system 10 applied to a hazardous waste incinerator feeding device is provided. The photoelectric detection module 200 includes a power supply 210 and a detector 220. The power supply 210 is electrically connected to the detector 220 and the power supply 210 is used to supply power to the detector 220.

[0052] Understandably, power supply 210 provides the necessary electrical energy to detector 220, ensuring that detector 220 can operate continuously and stably, enabling real-time monitoring of the materials transported on feeding device 100. By providing a stable power supply 210 to detector 220, false alarms or malfunctions of detector 220 caused by power supply fluctuations can be reduced, thereby improving the reliability of the entire fire extinguishing system.

[0053] Detector 220 can detect flames generated during material transportation, including information on the location and intensity of the flames, which is crucial for the timely response of the fire suppression system. Once detector 220 detects a flame, it transmits a signal to the control system, thereby triggering the activation of the carbon dioxide fire suppression unit 300.

[0054] In some embodiments, the detector 220 is an infrared detector, an ultraviolet detector, or an infrared and ultraviolet detector.

[0055] Understandably, infrared detectors can sense the infrared radiation produced by flames. Because flames release a large amount of infrared heat energy during combustion, infrared detectors can accurately capture these heat signals and convert them into electrical signals for further processing. Infrared detectors are particularly effective at identifying high-temperature flames because they can directly respond to the heat energy generated by the flame, reducing false alarms caused by interference from other non-flame heat sources.

[0056] Ultraviolet (UV) detectors, on the other hand, focus on capturing the ultraviolet radiation emitted by flames. Flames produce specific ultraviolet wavelengths when burning, wavelengths unique to flames, allowing UV detectors to identify flame signals more accurately. Compared to infrared detectors, UV detectors have higher sensitivity in identifying flames because they can capture the finer light signals produced by flames.

[0057] The infrared and ultraviolet detector 220 can combine the advantages of the two detectors mentioned above.

[0058] Reference Figure 1 According to the present invention, a carbon dioxide fire extinguishing system 10 applied to a hazardous waste incinerator feeding device is provided. The photoelectric detection module 200 includes multiple probes 221, which are respectively disposed on both sides of the feeding device 100 extending along the transport direction.

[0059] Understandably, by distributing multiple probes 221 on both sides of the feeding device 100 extending along the transport direction, it can be ensured that the flame can be captured by at least one probe 221 at any position during material transport. This arrangement significantly improves the coverage of flame detection and reduces missed detections caused by blind spots of the detector 220. Simultaneously, the presence of multiple probes 221 allows for mutual verification, improving the accuracy of flame identification and reducing the false alarm rate.

[0060] In one embodiment, the infrared spectrum of the detector 220 is in the range of 155 nm to 265 nm.

[0061] Understandably, setting the spectral range of detector 220 to 155nm–265nm allows it to more accurately capture the specific infrared radiation emitted by flames. Flames emit infrared radiation of specific wavelengths during combustion, especially under high-temperature conditions. Selecting an appropriate spectral range can improve detector 220's ability to identify flame characteristics, ensuring accurate early fire detection.

[0062] Limiting the infrared spectral range helps filter out interference signals from non-flame heat sources, reducing the likelihood of false alarms. Many other heat sources exist in the natural environment (such as machinery and ambient temperature changes), which may also emit infrared radiation, but their spectral characteristics differ from those of flames. By selecting a specific spectral range, detector 220 can better distinguish between genuine flames and other heat sources, reducing false alarm rates and improving system reliability.

[0063] In one embodiment, the ultraviolet spectral range of the detector 220 is 2.1µm to 2.7µm.

[0064] Understandably, detector 220 is set within a specific spectral range of 2.1µm to 2.7µm, a range that typically matches the ultraviolet radiation characteristics emitted by a flame. Therefore, detector 220 can more effectively detect the presence of a flame. By focusing on the flame-specific ultraviolet spectral range, detector 220 can reduce false alarms from other non-flame sources, such as ordinary lighting or ambient heat, thereby improving detection accuracy. Different combustible materials produce ultraviolet radiation of different wavelengths. Setting a specific spectral range allows detector 220 to better adapt to specific types of flames, such as the special flames that may occur during hazardous waste incineration.

[0065] In one embodiment, the voltage of the power supply 210 is 24V to 26V.

[0066] Understandably, in a fire suppression system, a 24V–26V power supply 210 ensures that all detectors 220 in the system operate within their normal operating range. The power supply 210, with its voltage set within the 24V–26V range, provides stable power support.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
