Description

Technical Field

[0001] The invention relates to the technical field of perfluorohexanone fire extinguishing, in particular to a perfluorohexanone fire extinguishing device with a waste gas absorption structure. Background Art

[0002] Halon fire extinguishing agent is a commonly used fire extinguishing agent. However, its ozone depletion potential (ODP) and global warming potential (GWP) are extremely high, and its atmospheric lifetime (ALT) is as long as several dozen to hundreds of years. Therefore, the use of this fire extinguishing agent is not in line with the current sustainable development strategy.

[0003] In this regard, it is urgent to find a green and environmentally friendly fire extinguishing agent. As a new type of fire extinguishing agent, perfluorohexanone has a boiling point of 49.2°C at standard atmospheric pressure, which allows it to vaporize quickly and lower the ambient temperature. In addition, perfluorohexanone has an ODP of 0, a GWP of 1, and an ALT of 0.014 years. It has a low greenhouse effect and no effect on the ozone layer. Not only that, perfluorohexanone also has excellent insulation properties and is non-corrosive. Therefore, perfluorohexanone fire extinguishing agent has been widely used, especially in confined spaces such as high and low voltage distribution cabinets, charging piles, and energy storage power stations.

[0004] Perfluorohexanone itself is non-toxic, but it will decompose under high temperature and produce toxic products such as CO and HF. Other thermal decomposition products may also be potentially harmful. At the same time, the existing fire extinguishing device only has the function of extinguishing the fire, and the thermal decomposition products after the fire is extinguished are not treated. These toxic components will threaten the health of firefighters. In addition, the fire extinguishing alarm device using perfluorohexanone fire extinguishing agent currently has the disadvantages of low automation level, relatively single function, small fire extinguishing range, etc., which makes it difficult to achieve flexible fire extinguishing in a targeted manner.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figures 1-2 , which is the first embodiment of the present invention, and which provides a perfluorohexanone fire extinguishing device with an exhaust gas absorption structure,

[0031] Specifically, a fire extinguishing module is used for storing and spraying perfluorohexanone fire extinguishing agent;

[0032] Exhaust gas treatment module, used to absorb and purify harmful gases generated during fire extinguishing;

[0033] The control module is used to coordinate the work of each module and make intelligent decisions.

[0034] Furthermore, the fire extinguishing module includes a perfluorohexanone cylinder, an automatic tracking and positioning perfluorohexanone electromagnetic spray component, and multiple sensors. The perfluorohexanone cylinder is made of corrosion-resistant alloy steel material. The perfluorohexanone cylinder is provided with a solenoid valve, and the switch is controlled by the control module. The automatic tracking and positioning perfluorohexanone electromagnetic spray component can automatically locate the fire source and adjust the spray direction according to the sensor data.

[0035] Furthermore, the multiple sensors include fog sensors, flame sensors, temperature sensors and cameras, and the cameras are used to monitor the environment in real time and assist in locating the fire source.

[0036] Furthermore, the fire extinguishing module also includes an audible and visual alarm and a remote alarm, which are connected to the control module and are used for simultaneous on-site and remote alarms. The audible and visual alarm is installed on the top of the metal box, and the metal box is set to a multi-layer composite flame retardant material.

[0037] Furthermore, the exhaust gas treatment module includes an active air intake component, a smoke particle filtering component, an HF absorption box, a CO absorption box, a CO2 / CF4 / fluorinated organic absorption box, a CO concentration detector and an HF concentration detector, and the active air intake component includes a small vacuum pump for automatically adjusting the air intake rate according to the exhaust gas concentration.

[0038] Furthermore, the smoke particle filtering assembly includes a ULPA filter, which has the ability to capture particles efficiently. The air inlet of the ULPA filter and the air outlet of the CO2 / CF4 / fluorinated organic matter absorption box are both equipped with solenoid valves for controlling the gas flow direction.

[0039] Furthermore, the absorption liquid in the HF absorption box is deionized water, the absorption liquid in the CO absorption box is a palladium-based catalyst, and the absorption liquid in the CO2 / CF4 / fluorine-containing organic matter absorption box is a NaOH solution added with activated carbon.

[0040] Preferably, the absorption liquid in the CO absorption box is a palladium-based absorbent, which can convert CO into CO2 through palladium-catalyzed CO oxidation reaction, and then CO2 is absorbed by the subsequent absorption box. The absorption liquid in the CO2 / CF4 / fluorinated organic matter absorption box is a NaOH solution, which is absorbed through chemical reaction. Although the CO2 / CF4 / fluorinated organic matter absorption box is not equipped with a corresponding concentration detector, the possible thermal decomposition products of perfluorohexanone can be predicted, so this absorption box is set.

[0041] Preferably, the exhaust gas absorption box used in the exhaust gas treatment module of the present device is more efficient and has a better exhaust gas absorption effect. For example, the ULPA filter also has a better effect on smaller particles. The HF absorption box uses deionized water as the absorption liquid, which is more efficient and economical. The CO absorption box uses a target-based absorbent, which has a large adsorption capacity compared to the CuCl-MgCl2 aqueous solution used in the prior art and usually exists in solid form. It does not require solution configuration and treatment when used, and will not generate compounds containing heavy metals. It can convert CO into non-toxic CO2.

[0042] Further, the HF concentration detector and the CO concentration detector are used to detect the gas concentration after the exhaust gas is absorbed;

[0043] When it is detected that the gas concentration exceeds the standard, the control module controls the exhaust gas to re-enter the exhaust gas treatment module for circulation treatment until it meets the emission standards.

[0044] Preferably, when it is detected that the concentrations of CO and HF exceed the preset values, and the small intelligent controller issues a successful fire extinguishing command, the intelligent exhaust gas collection device for the perfluorohexanone fire extinguishing agent is automatically started, mainly absorbing toxic gases such as HF and CO, and also absorbing exhaust gases such as CO2, CF4, and fluorine-containing organic matter. The active suction device is started, and the absorbed gas is first filtered through a gas particle filter device to filter the smoke in the gas, and then passed through an HF absorption box, a CO absorption box, and a CO2 / CF4 / fluorine-containing organic matter absorption box in turn for absorption. The HF concentration sensor and the CO concentration sensor detect the tail gas after absorption. If the HF concentration, the CO concentration, or the smoke particles do not meet the emission standards, the tail gas is refilled into the absorption device until it meets the emission standards, and then released, so that the perfluorohexanone thermal decomposition gas can be absorbed and treated by the exhaust gas treatment module.

[0045] Furthermore, the control module includes a small intelligent controller for processing sensor data, controlling system operation and conducting fire situation analysis. The small intelligent controller can push fire information to a remote monitoring terminal through communication.

[0046] Furthermore, the control module is used to: intelligently judge the fire situation and control the fire extinguishing module, automatically control the exhaust gas treatment module, process the monitoring data and perform trend analysis, control the alarm module, transmit data to the remote monitoring terminal, and execute the self-diagnosis program.

[0047] It should be noted that the smoke sensor, flame sensor, temperature sensor, camera, and temperature sensor will feed back the data measured in the environment to the small intelligent controller. If one of the following is detected: the temperature is too high, there is a fire source, or there is smoke, the solenoid valve of the perfluorohexanone cylinder will open, and the perfluorohexanone will be sprayed toward the fire source from the automatic tracking and positioning perfluorohexanone electromagnetic spraying device through a metal hose, so that the fire can be controlled and extinguished. Solenoid valves are installed on the left and right sides of the ULPA filter inlet and the CO2 / CF4 / fluorinated organic absorption box outlet, which can be controlled to be turned on and off by the small intelligent controller; the above-mentioned small intelligent controller is connected to the camera, sound and light alarm, smoke alarm, flame alarm, HF concentration detector, CO concentration detector, perfluorohexanone cylinder solenoid valve, ULPA filter inlet solenoid valve, CO2 / CF4 / fluorinated organic absorption box outlet solenoid valve, and perfluorohexanone automatic tracking nozzle by wires.

[0048] When in use, the small intelligent controller, smoke sensor, flame sensor, HF concentration detector, CO concentration detector, and camera are always in working state to monitor the environment of the equipment; the sensor feeds back the data measured by the environment to the small intelligent control system. If a fire source, temperature rise, or smoke is detected, the solenoid valve of the perfluorohexanone cylinder will automatically open, and the perfluorohexanone will enter the metal hose pipe. Then the perfluorohexanone will automatically track the fire source information transmitted to the small intelligent controller by the camera, and spray perfluorohexanone to the fire source. At the same time, the sound and light alarm will sound, and the small intelligent controller will transmit the information of each sensor to the monitoring end of the studio through communication, so that the staff can see the fire situation around the equipment in real time. When the flame is extinguished, the small intelligent controller sends a successful fire extinguishing command. If the smoke sensor detects that the ambient smoke concentration exceeds the standard, the CO concentration detector detects that the CO concentration exceeds the standard, and the HF concentration detector detects that the HF concentration exceeds the standard, the small exhaust fan is started to suck the exhaust gas into the ULPA filter for particle filtration, followed by the HF absorption box for HF gas filtration, followed by the CO absorption box for CO filtration, and then the CO2 / CF4 / fluorinated organic absorption box for CO2 and CF4 fluorinated organic filtration. If the CO concentration detector and the HF concentration detector detect that the purified gas meets the safety and environmental protection standards, the right solenoid valve of the last absorption box is opened to discharge the exhaust gas from the protected equipment; if it does not meet the safety and environmental protection standards, the left solenoid valve of the last absorption box is opened to re-discharge the purified gas into the exhaust gas absorption device for reabsorption until the purified gas discharged to the outside meets the safety and environmental protection standards. Finally, the filtered purified gas is discharged into the atmosphere. When the smoke and dust in the enclosed space where the device is located is purified, and gases such as CO, HF, CF4, CO2 and fluorinated organic matter are purified, the solenoid valves on the left and right sides of the perfluorohexanone cylinder and the ULPA filter and the CO2 / CF4 / fluorinated organic matter absorption box will be closed, and various sensors and cameras will continue to work, constantly detecting the environment in which the equipment is located and feeding back data to the small intelligent control system.

[0049] like Figure 2As shown, the device is first started. When the smoke in the air reaches the preset concentration value of the smoke sensor, it is determined that the smoke sensor is in action; when the flame sensor detects an open flame, it is determined that the flame sensor is in action; the camera transmits the images around the device to the small intelligent controller in real time; when the temperature sensor detects that the temperature in the air reaches the preset high temperature, it is determined that the temperature sensor is in action; when the HF concentration detector detects that the HF concentration in the air is higher than the preset value, it is determined that the HF concentration detector is in action; when the CO concentration detector detects that the CO concentration in the air is higher than the preset value, it is determined that the CO concentration detector is in action. Then the small intelligent controller processes and analyzes the data transmitted by each sensor. If one of the first four sensors is in action, the sound and light alarm is activated; at the same time, perfluorohexanone is started to extinguish the fire, the solenoid valve of the perfluorohexanone cylinder is opened, and then the perfluorohexanone agent enters the pipeline. At the same time, the nozzle automatically tracks the flame, smoke, and high temperature, and the position and direction of the nozzle are corrected in real time through the camera. If the sensor does not detect the flame and the temperature drops, the fire is successfully extinguished. If the fire is not extinguished successfully, the small intelligent controller will not issue a successful fire extinguishing command, and the exhaust gas absorption device will not start; if the fire is extinguished successfully, the small intelligent controller will issue a successful fire extinguishing command, and if the sensor detects a decrease in temperature, no open flame, an increase in HF concentration, and an increase in CO concentration, the small exhaust fan will start, and then the exhaust gas pumped into the pipeline will be absorbed by the ULPA filter, HF absorption box, CO absorption box, CO2 / CF4 / fluorinated organic absorption box in turn. If the HF and CO concentrations emitted by the last absorption box meet the emission standards, the absorbed gas can be discharged into the air; if it does not meet the standards, the exhaust gas will be re-absorbed by the absorption device through the solenoid valve until the exhaust gas meets the safety and environmental protection standards, and then it will be discharged.

[0050] In summary, the present invention realizes the intelligent linkage of fire extinguishing and exhaust gas absorption by cleverly combining the fire extinguishing module and the exhaust gas treatment module. The device adopts a variety of sensors and a rotatable camera to improve the accuracy and visualization of fire detection. The exhaust gas absorption system adopts a high-efficiency ULPA filter and a specially designed absorbent, which can effectively treat a variety of harmful gases including HF and CO. By sharing sensors and control modules, the device not only saves costs and space, but also can achieve precise fire extinguishing and intelligent exhaust gas treatment.

[0051] The shell of this device adopts a metal box design with a flame retardant layer, which improves the fire resistance and can be used multiple times. The control module can intelligently judge the fire situation and fire extinguishing effect based on the sensor data, and only start the exhaust gas absorption device when the fire is successfully extinguished and the concentration of harmful gases reaches the preset value, avoiding the impact on the fire extinguishing effect. The overall design is compact, suitable for small confined spaces, and has remote monitoring function, which greatly improves the efficiency and safety of fire prevention and control.

[0052] Example 2

[0053] In order to verify the performance of the perfluorohexanone fire extinguishing device with exhaust gas absorption structure of the present invention, the researchers conducted a series of tests in a simulated data center environment. The test site is a closed space with an area of ​​100 square meters, which is equipped with multiple server cabinets to simulate a real data center environment.

[0054] First, the researchers installed the fire extinguishing device of the present invention in the test space, including a fire extinguishing module, an exhaust gas treatment module, and a control module. The fire extinguishing module is equipped with a 100 kg perfluorohexanone cylinder made of corrosion-resistant alloy steel and equipped with a solenoid valve for control. Automatic tracking and positioning perfluorohexanone electromagnetic spraying assemblies are installed in the four corners of the room to ensure all-round coverage. A variety of sensors, including fog sensors, flame sensors, temperature sensors, and high-definition cameras, are strategically arranged throughout the space.

[0055] The exhaust gas treatment module is installed on one side of the room and includes an active air inhalation component, a smoke particle filter component, an HF absorption box, a CO absorption box, and a CO2 / CF4 / fluorinated organic absorption box. ULPA filters are installed at the air inlet of the exhaust gas treatment module to ensure efficient particle filtration. The control module is installed in the operating room outside the room and communicates with various sensors and components through a network connection.

[0056] The testing process is divided into three stages: fire detection, fire extinguishing process and exhaust gas treatment.

[0057] In the first phase, the researchers simulated an electrical fire in a server cabinet. The control module quickly detected the fire through multiple sensors and immediately activated the sound and light alarm and remote alarm.

[0058] In the second stage, the fire extinguishing module is automatically activated. The automatic tracking and positioning perfluorohexanone electromagnetic spraying assembly adjusts the spraying direction according to the location of the fire source, and accurately sprays perfluorohexanone fire extinguishing agent toward the fire point. At the same time, the control module continuously monitors the development of the fire and adjusts the spraying amount and duration as needed.

[0059] In the third stage, after the fire is extinguished, the exhaust gas treatment module automatically starts. The active suction component starts working and draws the exhaust gas in the room into the treatment system. The exhaust gas first passes through the ULPA filter to remove particles, and then passes through the HF absorption box, CO absorption box and CO2 / CF4 / fluorinated organic absorption box in turn for treatment. During the whole process, the CO concentration detector and HF concentration detector continuously monitor the concentration of harmful gases in the exhaust gas to ensure that the treated gas meets the emission standards.

[0060] The researchers recorded various parameters throughout the process, including fire detection time, fire extinguishing time, exhaust gas treatment time, and harmful gas concentrations before and after treatment. At the same time, they also recorded the performance of traditional fire extinguishing systems under the same conditions for comparative analysis. The test results are shown in the following table:

[0061] parameter Fire extinguishing device of the present invention Traditional fire extinguishing system National standard requirements unit Fire detection time 3.2 8.5 ≤10 Second Fire extinguishing time 12.5 25.3 ≤30 Second Waste gas treatment time 180 N / A ≤300 Second HF concentration (before treatment) 12.5 15.2 / ppm HF concentration (after treatment) 0.8 14.8 ≤1 ppm CO concentration (before treatment) 85 92 / ppm CO concentration (after treatment) 5.2 89 ≤9 ppm CO2 concentration (after treatment) 450 3200 ≤1000 ppm Equipment damage degree slight Moderate / /

[0062] Through the analysis of the above data, we can draw the following conclusions:

[0063] Fire detection time: The fire extinguishing device of the present invention can detect a fire in just 3.2 seconds, which is 5.3 seconds faster than the traditional fire extinguishing system, increasing the detection speed by 62.4%. This is due to the coordinated work of multiple sensors and the rapid response capability of the intelligent control module, which greatly reduces the risk of fire spreading.

[0064] Fire extinguishing time: The fire extinguishing device of the present invention extinguishes the fire within 12.5 seconds, which is 12.8 seconds faster than the traditional system, and improves the fire extinguishing efficiency by 50.6%. This is mainly due to the precise positioning and injection of the automatic tracking and positioning perfluorohexanone electromagnetic spraying assembly, as well as the high efficiency of the perfluorohexanone fire extinguishing agent.

[0065] Waste gas treatment: The waste gas treatment module of the present invention completes the waste gas treatment within 180 seconds, which is far lower than the national standard requirement of 300 seconds. The traditional system does not have the waste gas treatment function, which is a major innovation and advantage of the present invention.

[0066] Harmful gas concentration: After exhaust gas treatment, the device of the present invention reduces the HF concentration from 12.5ppm to 0.8ppm, the CO concentration from 85ppm to 5.2ppm, and the CO2 concentration is controlled at 450ppm. These values ​​are lower than the national standard requirements and are significantly better than the traditional system. In particular, the treatment effects of HF and CO are reduced by 94.6% and 94.2% respectively compared with the traditional system, which fully demonstrates the superiority of the present invention in environmental protection and personnel safety.

[0067] Equipment damage: Due to the rapid response and precise fire extinguishing of the device of the present invention, and the clean characteristics of the perfluorohexanone fire extinguishing agent, the equipment in the test suffered only minor damage. In contrast, the equipment damage caused by the traditional system was moderate, which highlights the advantages of the present invention in protecting high-value equipment.

[0068] Intelligent degree: The control module of the device of the present invention can automatically judge the fire situation, control the fire extinguishing process, manage the waste gas treatment, perform data analysis and remotely transmit information. This highly intelligent feature not only improves the efficiency of fire extinguishing, but also provides valuable data support for subsequent fire analysis and prevention.

[0069] Environmental friendliness: By efficiently treating harmful gases such as HF, CO, and CO2, the present invention greatly reduces the negative impact of the fire extinguishing process on the environment. This is especially important for places that require frequent fire drills or are located in environmentally sensitive areas.

[0070] In summary, the perfluorohexanone fire extinguishing device with an exhaust gas absorption structure of the present invention is significantly superior to the traditional fire extinguishing system in terms of fire detection speed, fire extinguishing efficiency, exhaust gas treatment capacity, equipment protection and environmental friendliness, and fully meets or even exceeds the requirements of national standards. Its innovation is mainly reflected in the integration of multiple advanced technologies such as intelligent control, precise fire extinguishing and efficient exhaust gas treatment, providing a comprehensive solution for modern fire safety systems. This integrated and intelligent design not only improves the fire extinguishing efficiency, but also minimizes the secondary pollution during the fire extinguishing process, providing more comprehensive protection for personnel, equipment and environmental safety.

[0071] Example 3

[0072] In order to verify the exhaust gas absorption efficiency of the exhaust gas absorption structure of the device, the air is mixed with HF, CO, CO2, CF4, other fluorine-containing organic gases, and particles with a particle size of less than or equal to 2.5m to test its purification efficiency. Four concentration gradients are made for each group of gases or particles, and the results are shown in Table 1 and Table 2 respectively:

[0073] Table 1 Evaluation results of each gas purification efficiency

[0074]

[0075]

[0076] Table 2 Evaluation results of particle purification efficiency

[0077]

[0078] It can be seen from Table 1 and Table 2 that the exhaust gas absorption structure has a good effect on the purification of exhaust gas and particulate matter. The average absorption rate of HF gas reaches more than 75%, and the average absorption rate of other exhaust gases reaches more than 80%. In addition, the absorption effect on small particulate matter is also relatively good, reaching more than 77%. Therefore, the perfluorohexanone fire extinguishing device with an exhaust gas absorption structure not only has excellent fire extinguishing performance, but also has good absorption and purification of exhaust gas.
