Description

Technical Field

[0001] This invention relates to the field of fire protection equipment technology, and in particular to an integrated multi-functional gas-liquid mixer and fire protection equipment. Background Technology

[0002] In recent years, compressed air foam fire extinguishing technology has become an important development direction in the fire protection industry due to its advantages such as high fire extinguishing efficiency, strong fire control capability, low water damage, and good environmental adaptability. The gas-liquid mixing device that can be adapted to bottle-type fire extinguishing equipment and realize efficient mixing of gas and liquid phases is the core key component for the application of this technology in bottle-type fire extinguishing equipment, and has also become a key research and development direction in the industry.

[0003] Currently, the gas-liquid mixers widely used in the industry generally adopt a vertical single-hole injection structure, which has revealed several shortcomings in practical engineering applications: First, this structure makes it difficult to accurately control the gas-liquid mixing ratio, resulting in poor uniformity of the gas-liquid two-phase mixture. It cannot stably generate compressed air foam with satisfactory foaming effect and stable fire extinguishing performance, and it also causes significant pressure loss to the system piping network, affecting the spray distance and coverage of the extinguishing agent. Second, bottle-type fire extinguishing equipment is in a standby state for extended periods, and the foam mixture stored in the bottles is prone to condensation and stratification after prolonged standing. Existing mixers lack corresponding pretreatment structures, failing to address the problems of poor liquid absorption, decreased foam quality, and reduced fire extinguishing performance caused by stratification. Third, the existing mixer structure lacks flexibility, unable to flexibly adjust the gas-liquid mixing ratio according to the fire extinguishing scenario and foam liquid type, resulting in poor adaptability to different operating conditions. Therefore, improvements are necessary. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The gas-liquid mixer of the present invention adopts a dual-path split-flow gas-liquid mixing structure. By setting a compressed air pipe and a split pipe at the upper and lower ends of the air inlet chamber respectively, the driving airflow is divided into two paths that act simultaneously: one path is sent downward into the foam liquid storage area, which not only promotes the foam liquid to enter the suction pipe through airflow pressurization, but also uses airflow oscillation to avoid the foam liquid from stagnation and stratification due to long-term static state, thus solving the problem of poor liquid absorption and reduced fire extinguishing performance caused by long-term static stratification of foam extinguishing agent; the other path is sent upward into the mixing chamber, where it completes secondary gas-liquid mixing with the foam liquid sent out by the suction pipe, which greatly improves the uniformity of gas-liquid mixing and ensures the foaming effect and fire extinguishing performance of the foam extinguishing agent. Furthermore, by setting a purely mechanical proportional valve with dual-diameter flow holes in the liquid suction chamber, the flow holes can be switched by rotating the adjustment wheel to precisely adjust the foam liquid delivery flow rate, thereby achieving flexible adjustment of the gas-liquid ratio of the gas-liquid mixture and improving the adaptability of the equipment to different foam liquid types in different fire extinguishing scenarios.

[0017] The fire-fighting equipment of the present invention uses an integrated gas source system that uses air as raw material to adsorb, capture, compress and store carbon dioxide. This means that the device does not need to rely on specific gas sources with high carbon dioxide content such as factory exhaust gas, nor does it need to set up a complex deep purification and compression mechanism. It can meet the needs of fire-fighting driving gas source by directly capturing carbon dioxide from the air through long-term low-power continuous operation. At the same time, it greatly reduces the equipment manufacturing and full life cycle operation and maintenance costs. The equipment installation and layout are not limited by the gas source, and the application scenarios are more flexible. It is compatible with the core needs of fire-fighting equipment with extremely low usage frequency and long standby standby. This invention constructs an independent power supply system using photovoltaic panels and energy storage batteries. Its long-term low-power power supply characteristics are perfectly matched with the continuous carbon dioxide capture operation of the equipment, eliminating the need to continuously occupy the power grid in the plant area and reducing installation restrictions. At the same time, it can maintain the stable operation of the entire system even in extreme conditions where the plant's circuit is interrupted due to a fire, greatly improving the reliability and safety of fire protection equipment operation.

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1 to 4 As shown in the figure, the present invention provides an integrated multifunctional gas-liquid mixer, including a mixer housing 101. An output nozzle is fixedly connected to the top edge of the mixer housing 101. A base 102 is fixedly connected to the bottom of the mixer housing 101. A liquid suction chamber 108 is formed in the middle of the base 102, and a liquid suction pipe 104 is fixedly connected to the bottom of the liquid suction chamber 108. An air inlet chamber 105 is provided on one side of the base 102. An air inlet pipe 109 is fixedly installed in the middle of the air inlet chamber 105. A pressure pipe 106 is fixedly connected to the bottom of the air inlet chamber 105, and a diverter pipe 107 is fixedly connected to the top of the air inlet chamber 105. By installing a compressed air pipe 106 and a diverter pipe 107 at the upper and lower ends of the air inlet chamber 105 respectively, the airflow delivered by the air inlet pipe 109 is divided into two parts. One part is sent downward to the location of the foam liquid. The increased pressure from the airflow pushes the foam liquid into the suction pipe 104. At the same time, the gas is used to agitate the foam liquid, effectively avoiding the impact of stagnation and stratification caused by long-term stasis of the foam liquid on the discharge operation of the suction pipe 104. The other part of the gas is sent upward and mixed with the foam liquid discharged from the suction pipe 104 for a second time, which effectively improves the gas-liquid uniformity of the foam liquid delivered by the suction pipe 104 and improves the fire extinguishing performance of the gas foam extinguishing agent. In one embodiment, to prevent excessive pressure from occurring in the foam liquid container during storage or use, a pressure relief chamber is provided on the other side of the base 102 of this application, and a pressure relief valve 117 is fixedly installed on one side of the pressure relief chamber.

[0022] In one embodiment, to adjust the gas-liquid ratio delivered by the mixer, a proportional valve 115 is rotatably installed in the middle of the suction chamber 108. The proportional valve 115 includes a valve core, and two mutually perpendicular flow holes are opened in the middle of the valve core. The diameter of one flow hole is larger than that of the other flow hole, and the size of both flow holes is not larger than the inner diameter of the suction chamber 108. An adjusting wheel 116 is fixedly connected to one end of the valve core. The rotation angle of the adjusting wheel 116 is ninety degrees. By adjusting the rotation of the adjusting wheel 116, the flow hole facing the suction chamber 108 is changed, thereby adjusting the flow rate of the foam liquid delivered by the suction pipe 104, realizing the control of the gas-liquid ratio of the delivered gas-liquid mixture, and improving the flexibility of the gas-liquid mixer.

[0023] In one embodiment, to further improve the uniformity of gas-liquid mixing in this application, a partition 110 is fixedly connected to the top of the inner wall of the mixer housing 101, a plurality of liquid outlet nozzles 111 are installed on the top of the partition 110, and a compressed air nozzle 113 is installed at the bottom of the compressed air pipe 106. Both the liquid outlet nozzles 111 and the compressed air nozzles 113 are configured as rotating nozzles.

[0024] In one embodiment, to facilitate the flow of foam liquid from the suction pipe 104, the bottom of the suction pipe 104 is set at an angle towards the side of the compressed air pipe 106. To avoid vibration during the airflow process affecting the positional stability of the compressed air pipe 106, the bottom side of the compressed air pipe 106 is fixedly connected to one side of the suction pipe 104 via a connecting piece 114.

[0025] In one embodiment, in order to achieve centralized collection and stable delivery of the mixed gas-liquid mixture, the output nozzle includes a flow guide 103, the upward protrusion of the flow guide 103 is configured as a pointed cone, and the top of the flow guide 103 is fixedly connected to an output pipe 112.

[0026] When the aforementioned gas-liquid mixer is in use, the driving gas is sent into the inlet chamber 105 through the inlet pipe 109 and is divided into two airflows. The first airflow is delivered downwards through the compressor pipe 106, and the second airflow is delivered upwards into the mixer housing 101 through the splitter pipe 107. The downwardly delivered airflow is ejected through the compressor nozzle 113, which on the one hand pressurizes the foam liquid storage container, pushing the foam liquid upwards through the suction pipe 104 into the suction chamber 108, and on the other hand impacts the foam liquid to create oscillation. The proportional valve 115 in the middle of the suction chamber 108 can be rotated by turning the adjusting dial 116 to rotate the valve core by 90 degrees, switching the two mutually perpendicular valve cores. Different diameter flow holes are used to align the corresponding diameter flow holes with the liquid suction chamber 108, and adjust the flow rate of foam liquid delivered by the liquid suction pipe 104 to control the gas-liquid mixing ratio. The foam liquid in the liquid suction chamber 108 is sprayed out through the liquid outlet nozzle 111 and mixed with the airflow sent upward by the diverter pipe 107 in the mixer housing 101 to complete secondary gas-liquid mixing. The mixed gas-liquid mixture is gathered by the partition 110 and sent to the output nozzle. After being concentrated by the upwardly protruding pointed cone-shaped guide shroud 103, it is stably delivered by the output pipe 112. When the pressure in the foam liquid container exceeds the limit, the pressure relief valve 117 on the pressure relief chamber on the other side of the base 102 automatically opens to relieve pressure.

[0027] like Figures 5 to 10 As shown, a fire-fighting device is used for fire protection in factory areas or large enclosed spaces such as warehouses and workshops. It includes a mounting frame 201, and several assembly frames 202 are fixedly installed on one side of the mounting frame 201. Each of the assembly frames 202 is equipped with a fire-extinguishing spray mechanism. The mounting frame 201 integrates the multiple fire-extinguishing spray mechanisms to meet the fire protection needs of large spaces. In one embodiment, see Figure 6 The fire extinguishing spray mechanism includes a pressure cylinder 301. A gas-liquid mixer as described above is fixedly installed at the cylinder opening of the pressure cylinder 301. The output pipe 112 of the output nozzle of the gas-liquid mixer is connected to a spray pipe 306. A spray valve is fixedly installed in the middle of the spray pipe 306. A clamping pipe 305 is fixedly connected inside the mounting frame 202. One end of the clamping pipe 305 is clamped to a gas filling pipe 304. One end of the gas filling pipe 304 is fixedly connected to an air inlet pipe 109. A gas filling valve is fixedly installed in the middle of the clamping pipe 305. A one-way valve 303 is fixedly installed at the end of the gas filling pipe 304 near the clamping pipe 305. A gas trapping mechanism is provided inside the mounting frame 201. A compression storage mechanism for compressing the gas trapped by the gas trapping mechanism is provided on the other side of the mounting frame 201. One end of the clamping pipe 305 is connected to the output end of the compression storage mechanism, thereby enabling control of the gas supply to each fire extinguishing spray mechanism according to usage needs.

[0028] In one embodiment, see Figure 7 and Figure 9The gas capture mechanism includes a packing frame 208, with an adsorption packing 206 placed on top of the packing frame 208. The adsorption packing 206 is an adsorbent for adsorbing carbon dioxide. In this embodiment, a polyurethane silica aerogel adsorbent is used. An electric heating grid 207 is fixedly installed in the middle of the adsorption packing 206. The heating of the electric heating grid 207 assists in the release of carbon dioxide from the adsorption packing 206. A base plate 209 is fixedly connected to the middle of the inner wall of the mounting frame 201. A gas collecting duct 210 is fixed to the top of the base plate 209. A gas collecting chamber 217 is provided at the bottom of the base plate 209. Several gas collecting ports 218 are opened on the side of the gas collecting chamber 217 near the compression storage mechanism. In this example, the gas capture mechanism is used to capture carbon dioxide from the air. The captured carbon dioxide is only used as a gas source, so the purity requirement for carbon dioxide is greatly reduced.

[0029] Compared to traditional carbon dioxide capture systems, this solution eliminates the need for complex deep purification and compression mechanisms to enrich carbon dioxide to meet usage requirements. It also avoids reliance on specific gas sources with high carbon dioxide content, such as factory exhaust. By simply capturing carbon dioxide directly from the air through continuous, long-term operation, it fulfills the application needs. Therefore, this solution offers greater flexibility, adapting to a wider range of scenarios while significantly reducing manufacturing, operation, and maintenance costs. Furthermore, given the extremely low frequency of use of fire-fighting equipment, the long-term continuous operation mode employed in this solution is well-suited to the actual needs of such equipment.

[0030] In one embodiment, see Figure 7 and Figure 8 The specific internal structure of the air collecting duct 210 can be implemented with reference to existing technologies, such as directly using a fan. In this example, a feasible structure for the air collecting duct 210 is provided. A partition plate 214 is fixedly connected inside the air collecting duct 210. An air collecting motor 211 is installed below the partition plate 214. The bottom of the air collecting motor 211 is fixedly connected to the inner wall of the air collecting duct 210 through a support frame 216. An annular frame is fixedly connected to the output end of the air collecting motor 211. Several guide vanes 213 are fixedly connected to the inner edge of the annular frame. A central filter tube 212 is fixedly connected to the middle of the annular frame. A filter membrane is fixedly connected to the middle of the central filter tube 212. An outlet 215 is opened at the bottom of the side wall of the central filter tube 212. The outlet 215 is located below the partition plate 214. The air collecting motor 211 drives the annular frame and guide vanes 213 to rotate, thereby driving the airflow to concentrate in the central filter tube 212. After filtration by the filter membrane, the airflow is finally discharged from the outlet 215. This assists the adsorption packing 206 in further purifying carbon dioxide, while also providing power for the gas to enter the mounting frame 201 and pass through the adsorption packing 206 and other structures, ensuring the continuous and stable operation of carbon dioxide capture.

[0031] In one embodiment, see Figure 7 and Figure 9 To filter oxygen and water vapor in the gas before it enters the adsorption packing 206, a filter packing 205 is placed on top of the adsorption packing 206. To filter and separate solid particles of dust and impurities in the air, a dust-proof frame is placed on top of the filter packing 205. A dust-proof membrane 204 is fixedly connected to the middle of the dust-proof frame. One side of the mounting frame 201 is inclined outward to form a slope. A collection window is opened in the middle of the slope. A dust-proof net 203 is fixedly connected to the inner wall of the collection window, thereby further reducing the probability of dust in the air entering the interior of the mounting frame 201.

[0032] In one embodiment, to provide power for the overall operation of the device, a movable frame 407 is slidably mounted on the top of the mounting frame 201. A photovoltaic panel 404 is fixedly mounted on the top of the movable frame 407. The photovoltaic panel 404 provides low-power power for extended periods, which can stably match the device's need for continuous long-term adsorption and capture of carbon dioxide. Using the photovoltaic panel 404 for power supply avoids continuous occupation of the plant's electrical energy during operation, making the installation and setup more convenient and flexible. Furthermore, the independent photovoltaic power supply ensures stable operation even during power outages in the plant during fires, thus improving equipment stability. To facilitate the unfolding of the photovoltaic panel 404 and increase its light-receiving area, a pusher frame 405 is provided on one side of the movable frame 407. Several pusher rollers 406 are rotatably mounted inside the pusher frame 405, and these rollers are all rolledly connected to the bottom of the movable frame 407. The rotation of the pusher rollers 406 pushes the movable frame 407 to move, thereby extending the photovoltaic panel 404 to the outside.

[0033] The aforementioned compression and storage mechanism is used to extract, collect, compress, and store the carbon dioxide gas temporarily stored in the gas collection chamber 217. Its specific structure can be implemented using existing technologies.

[0034] In this embodiment, a feasible structural form of a compression storage mechanism is provided. The compression storage mechanism includes a housing 401, a compression pump 402 is fixedly installed in the middle of the inner wall of the housing 401, the input end of the compression pump 402 is fixedly connected to a plurality of air collection ports 218 through a plurality of air collection pipes, and the output end of the compression pump 402 is fixedly connected to a pressurized air storage tank 403; In one embodiment, to provide power to the entire device, a battery 408 for supplying power to the device is fixedly installed at one end of the enclosure 401. The photovoltaic panel 404 is electrically connected to the battery 408, and other photovoltaic control components, such as the inverter adapted to the photovoltaic panel 404, are also included. All of these are implemented using existing technologies.

[0035] In use, ambient air enters the mounting frame 201 after being initially filtered by the dust-proof mesh 203 of the air-collecting window. It then passes through the dust-proof membrane 204 and filter media 205 of the dust-proof frame to filter solid impurities, water vapor, and excess oxygen. The air then comes into contact with the adsorption media 206 on the median frame 208, where the adsorption media 206 captures carbon dioxide from the air. After adsorption saturation, the electric heating mesh 207 in the middle of the adsorption media 206 is activated to heat the media. This heating assists in the release of carbon dioxide from the adsorption media 206, allowing the adsorbed carbon dioxide to desorb. The gas-collecting motor 211 inside the gas-collecting duct 210 drives the annular frame and guide vanes 213 to rotate, concentrating the airflow towards the central filter pipe 212. After secondary filtration by the filter membrane, the gas is temporarily stored in the gas-collecting chamber 217 at the bottom of the base plate 209 through the outlet 215. During this process, the photovoltaic panel 404 on top of the mounting frame 201 converts solar energy into electrical energy, which is stored in the battery 408 of the compression storage mechanism, providing independent power for the entire operation of the equipment. During this time, the push roller 406 in the push frame 405 can rotate, driving the movable frame 407 to move and extend the photovoltaic panel 404 to adjust its light-receiving area. The compression pump 402 of the compression storage mechanism draws carbon dioxide gas from the gas collection chamber 217 through the gas collection pipe, compresses it, and sends it to the pressurized gas storage tank 403 for storage. The pressure cylinder 301 of the fire extinguishing spray mechanism is integrated and fixed on the mounting frame 201 via the assembly frame 202. The gas-liquid mixer is installed at the mouth of the pressure cylinder 301. The air inlet pipe 109 of the gas-liquid mixer is connected to the clamping pipe 305 in the assembly frame 202. The clamping pipe 305 is connected to the output end of the pressurized gas storage tank 403. When a fire occurs, the gas filling valve and spray valve at the corresponding fire extinguishing point are opened. The carbon dioxide driving gas in the pressurized gas storage tank 403 is sent to the gas-liquid mixer through the clamping pipe 305. After the gas and liquid are mixed in the gas-liquid mixer, the resulting foam extinguishing agent is sprayed out through the spray pipe 306 to extinguish the fire. The one-way valve 303 in the clamping pipe 305 can prevent gas backflow and ensure stable gas supply. When the foam fire extinguisher is used up, it can continue to increase the carbon dioxide concentration in the factory area by sending out all the remaining carbon dioxide gas in the device, and continuously suppress the combustion in the factory area.

[0036] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
