Since water is cheap and easy to obtain and has a wide range of sources, the fire extinguishing agent used by fire trucks in most fires is mainly water, and sometimes a large amount of chemical fire extinguishing agents are also needed. The large amount of fire extinguishing agent required and the low efficiency will increase the fire loss, and the ejected fire extinguishing agent may also increase other losses besides the fire; at the same time, it will cause certain pollution to the environment and increase the difficulty of subsequent rescue and cleanup work.

[0035] In order to make the invention purpose, technical scheme and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0036] Figure 1 A schematic diagram of a fire truck with a temperature-activated water preparation system is shown. Figure 2 Figure 2 shows a schematic diagram of the piping system for the temperature-activated water preparation system. Figure 1 and Figure 2As shown, the fire truck includes a chassis 1, a transmission system 2, a generator 3, a water softener 4, a water tank 5, a pressurized heating device 6, an equipment box 7, a water outlet pipeline 8, a high-pressure and high-temperature hose 9, a spray gun 10 and an electrical control system 11. Among them, the transmission system 2, the generator 3, the water softener 4, the water tank 5, the pressurized heating device 6, the water outlet pipeline 8, the high-pressure and high-temperature hose 9, the spray gun 10 and the electrical control system 11 are all contained in the equipment box 7. Among them, the water tank 5 is connected to the water inlet of the pressurized heating device 6, and the pressurized heating device 6 can draw water from the water tank 5 and pressurize and heat it to produce metastable active water. The metastable active water can instantly turn into a fire-extinguishing cloud of temperature-active water when it contacts the external environment, so that the fire is reduced, and then the fire is extinguished and rescued. The use of the temperature-active water preparation system improves the efficiency of large-space fire extinguishing and rescue on the one hand, and on the other hand, only a small amount of water is used to quickly and effectively extinguish the fire, achieving energy saving and environmental protection. Furthermore, the above-mentioned pressurized heating device 6 adopted in the utility model, on the one hand, has a higher pressurized heating efficiency compared with the heating boiler heated by a diesel burner adopted in the traditional technology; on the other hand, compared with the traditional heating boiler and pressurizing device that can only set a fixed temperature and a fixed pressure, the above-mentioned metastable state active water generated by it has higher controllability and can generate the above-mentioned temperature active water with the required temperature and the required pressure according to the fire extinguishing environment.

[0037] In the above embodiment, the pressurized heating device 6 includes a high-pressure water pump 6-1, a motor 6-2, a water inlet pipe 6-3, a heating combustion furnace 6-4 and a hot water outlet pipe 6-7. One end of the high-pressure water pump 6-1 is connected to the water tank 5 through a water pipe, and the other end of the high-pressure water pump 6-1 is connected to the water inlet of the heating combustion furnace 6-4 through the water inlet pipe 6-3, and the water outlet of the heating combustion furnace 6-4 is connected to the hot water outlet pipe 6-7. During operation, the pressurized heating device 6 is driven by the motor 6-2 so that the high-pressure water pump 6-1 can absorb ordinary water from the water tank 5 and pressurize the ordinary water to obtain high-pressure water. The motor 6-2 further transports the high-pressure water to the heating combustion furnace 6-4 through the water inlet pipe 6-3, and heats the high-pressure water to produce the metastable active water. At this time, the hot water outlet pipe 6-7 contains high-temperature and high-pressure metastable active water. The metastable active water is sprayed into the external environment, and the metastable active water can instantly become high-temperature active water for fire extinguishing.

[0038] Here, the principle of the transformation of the metastable active water into the temperature active water is introduced. When the high-temperature and high-pressure metastable active water is discharged to the external environment (i.e., the fire scene or the atmospheric environment) through the hot water outlet pipe 6-7, due to the sudden drop in the ambient temperature and pressure, a strong vapor-liquid phase change process will occur, and the number of vaporized nuclei will increase sharply, resulting in explosive boiling of the metastable active water. After the metastable active water undergoes intense surface evaporation and boiling vaporization (i.e., explosive boiling), the metastable active water is instantly transformed into a fire-extinguishing cloud of temperature-active water and diffuses toward the fire scene. The droplets of some of the fire-extinguishing clouds are further condensed into smaller droplets when they are cooled during the diffusion process. Therefore, the volume of droplets generated by phase change processes such as explosive boiling and steam condensation will be much smaller than the volume of droplets generated by the single-phase atomization process of the traditional fine water mist nozzle, thereby improving the fire extinguishing efficiency.

[0039] In simple terms, the temperature active water is a mixture of steam and water droplets, which is the moment when the metastable active water changes from high temperature and high pressure to normal temperature and normal pressure (at 10 -9 ~10 -4 The temperature-activated water is obtained by converting the temperature of the air (within seconds) and is mainly applicable to fires of combustible materials that will not react chemically with water. The components of temperature-activated water are underheated steam and water droplets, the size of which is 0.01 to 10.0 microns. Most water droplets have a diameter of 0.01-10.0 microns. Therefore, the temperature-activated water jet is suspended in the air and will not settle for a long time (20 to 40 minutes), and will not settle even if it bypasses obstacles.

[0040] In the above embodiment, preferably, the pressurized heating device 6 further includes a pressure relief valve 6-5; wherein the pressure relief valve 6-5 is connected to the hot water outlet pipe 6-7, and can automatically release pressure when the hot water pressure in the hot water outlet pipe 6-7 exceeds a predetermined pressure. For example, when the pressure relief valve 6-5 is pre-set with a maximum pressure, if the high-pressure water pump 6-1 is out of control, causing the internal pressure of the pressurized heating device 6 to exceed a preset range, or if the heating combustion furnace 6-4 is out of control, causing too much water vapor, causing the internal pressure of the pressurized heating device 6 to exceed a preset range, the pressure relief valve 6-5 will automatically release pressure to release excess air or steam, thereby ensuring the safety of the operation of the pressurized heating device 6.

[0041] In the above embodiment, preferably, the pressurized heating device 6 further includes a safety valve 6-6; wherein the safety valve 6-6 is connected to the hot water outlet pipe 6-7, and can automatically release pressure when the hot water pressure in the hot water outlet pipe 6-7 exceeds a predetermined pressure. For example, when the maximum pressure is preset for the safety valve 6-6, if the high-pressure water pump 6-1 is out of control, causing the internal pressure of the pressurized heating device 6 to exceed a preset range, or if the heating combustion furnace 6-4 is out of control, causing too much water vapor, causing the internal pressure of the pressurized heating device 6 to exceed a preset range, the safety valve 6-6 will automatically release pressure to release excess air or steam, thereby ensuring the safety of the operation of the pressurized heating device 6.

[0042] In the above embodiment, preferably, when the hot water pressure in the hot water outlet pipe 6-7 exceeds the predetermined pressure and the pressure relief valve 6-5 does not work, the safety valve 6-6 automatically releases pressure, or when the hot water pressure in the hot water outlet pipe 6-7 exceeds the predetermined pressure and the safety valve 6-6 does not work, the pressure relief valve 6-5 automatically releases pressure. Further, the pressure relief valve 6-5 and the safety valve 6-6 can be controlled by the electrical control system 11, and the pressure relief sequence can be freely selected. Such a setting can make the pressurized heating device 6 have multiple safety protections, ensure the safe operation of the pressurized heating device 6, and prevent personal injury.

[0043] In the above embodiment, preferably, the temperature active water preparation system further includes a water softening device 4, which softens the water injected into the water tank 5. After ordinary water is heated by the heating combustion furnace 6-4, scale will be accumulated in the heating combustion furnace 6-4 or the above pipelines, affecting the preparation and circulation of the metastable active water. Therefore, the water in the water tank 5 is softened in advance by the water softening device 4 to ensure the normal operation of the pressurized heating device 6.

[0044] In the above embodiment, preferably, the pressurization range of the high-pressure water pump 6-1 is set at 1.0-10.0 MPa, and the heating range of the heating combustion furnace 6-4 is set at 110°C-240°C, so that the metastable active water is 1.0-10.0 MPa and 110°C-240°C, which is more conducive to the generation of the temperature active water. Furthermore, the high-pressure water pump 6-1 and the heating combustion furnace 6-4 can be controlled by the electrical control system 11 to generate the temperature active water of the required temperature and pressure according to the fire extinguishing environment, further improving the flexibility of the fire fighting process.

[0045] In the above embodiment, preferably, the temperature-activated water preparation system further includes a generator 3, and the generator 3 provides electricity for the pressurized heating device 6. The generator 3 provides driving power for the motor 6-2. Preferably, the generator 3 provides heating power for the heating combustion furnace 6-4. Compared with the conventional technology of heating the heating boiler with a diesel burner, the use of the generator 3 to provide electric heating for the heating combustion furnace 6-4 has a more environmentally friendly and higher pressurized heating efficiency, and can more quickly increase the temperature and pressure in the heating combustion furnace 6-4, while also saving space, thereby reducing the size of the fire truck. Furthermore, the generator 3 can also provide pressurized power for the high-pressure water pump 6-1.

[0046] In the above embodiment, preferably, the temperature-activated water preparation system further includes an electrical control system 11 for controlling the operation of the high-pressure water pump 6-1, the motor 6-2 and the heating combustion furnace 6-4. For example, the electrical control system 11 can select the following temperature-activated water preparation methods according to the received instructions: if the electrical control system 11 determines that high-temperature and high-pressure temperature-activated water is to be prepared, the heating combustion furnace 6-4 is controlled to be heated to a preset high temperature, and the high-pressure water pump 6-1 is controlled to be pressurized to a preset high pressure; or if the electrical control system 11 determines that high-temperature and low-pressure temperature-activated water is to be prepared, the heating combustion furnace 6-4 is controlled to be heated to a preset high temperature, and the high-pressure water pump 6-1 is controlled to be pressurized to a preset low pressure; or if the electrical control system 11 determines that low-temperature and high-pressure temperature-activated water is to be prepared, the heating combustion furnace 6-4 is controlled to be heated to a preset low temperature, and the high-pressure water pump 6-1 is controlled to be pressurized to a preset high pressure; or if the electrical control system 11 determines that low-temperature and low-pressure temperature-activated water is to be prepared, the heating combustion furnace 6-4 is controlled to be heated to a preset low temperature, and the high-pressure water pump 6-1 is controlled to be pressurized to a preset low pressure. The electrical control system 11 can flexibly control the pressurization pressure and heating temperature of the high-pressure water pump 6-1 and the heating combustion furnace 6-4, thereby preparing the required temperature active water. Furthermore, the electrical control system 11 can also control the amount of water that the high-pressure water pump 6-1 absorbs from the water tank 5. This configuration enables the temperature active water preparation system to freely prepare the metastable active water of the required temperature, required pressure and required volume, and makes the data of the metastable active water more accurate, thereby improving the fire extinguishing efficiency.

[0047] In the above embodiment, preferably, the temperature active water preparation system also includes a water outlet pipeline 8, and the hot water outlet pipeline 6-7 is connected to the water outlet pipeline 8; wherein the metastable active water generated by the pressurized heating device 6 is output through the water outlet pipeline 8, so that the metastable active water can quickly generate the temperature active water.

[0048] In the above embodiment, preferably, the fire truck also includes a high-pressure and high-temperature hose 9, which is connected to the water outlet pipe 8; a spray gun 10, which is connected to the high-pressure and high-temperature hose 9, not only enables the metastable active water to quickly generate the temperature active water, but the multi-pipeline setting is also conducive to disassembly and reduces maintenance costs.

[0049] In the above embodiment, preferably, the fire truck also includes a transmission system 2, one end of which is connected to the power take-off on the chassis 1, and the other end is connected to the generator 3, for providing a power source for the generator 3 to achieve long-term continuous power generation of the generator 3 and improve the working efficiency of the fire truck.

The conduit 34 is connected to the temperature-activated water nozzle 36 through the outlet pipe 37. The metastable active water can pass through the conduit 34 and the outlet pipe 37 in sequence and be sprayed toward the fire scene by the temperature-activated water nozzle 36, so that the temperature-activated water can efficiently cover the fire scene and improve the fire extinguishing efficiency.

[0060] The advantages of using the utility model are that, first of all, it has higher energy efficiency. Taking 1kg of water as a unit, at the outlet of the temperature-activated water fire truck, the maximum thermal energy specific gravity of 1kg of water can be rapidly increased (for example, it can be increased from 500-1000kJ / kg to 2500-3000kJ / kg), providing the necessary energy for 1kg of steam water droplets to be produced after explosive boiling. After the explosive boiling, the steam content is also rapidly increased (for example, it can be increased from 20% to 80-90%), and the fire extinguishing efficiency is greatly improved compared with the traditional method. High; secondly, it is suitable for firefighting and rescue in large or confined spaces. The fire-extinguishing cloud of temperature-activated water of 1 liter per second can quickly fill a large space (such as 5 cubic meters of space). The jet can have the characteristics of not hurting the skin, below 42°C, and normal atmospheric pressure. It can not only achieve rapid cooling, dilute oxygen, 100% precipitate smoke, and achieve three-dimensional full-flooding fire extinguishing, but also isolate thermal radiation to ensure the personal safety of firefighters, fundamentally solving the water damage caused by the use of a large amount of water in the traditional firefighting process. Thirdly, it can work for a long time. The fire truck with temperature-activated water preparation system consumes very little water, and the fire extinguishing time lasts for a long time. Multiple (such as 2 to 3) active water fire extinguishing guns can work at the same time, and a small amount of water can work continuously for a long time (such as 3 tons of water can work continuously for nearly half an hour). In addition, it can also connect to an external water source, and the fire extinguishing work time is longer, which can avoid the risk of interrupting operations. Finally, it can provide water with the pressure and temperature required for various chemical decontamination requirements, which is more effective for on-site decontamination.

[0061] In other words, in the present invention, due to the special physical properties of the temperature-activated water, the temperature-activated water has four best fire-extinguishing effects: water cooling, nitrogen dilution, foam isolation, and chemical inhibitor fire-extinguishing. The temperature-activated water can effectively weaken the dispersed heat flow, and float for a long time to fill the fire scene, effectively protect the closed fire scene from heat radiation and perform three-dimensional fire extinguishing with maximum efficiency, which can not only prevent open flames from burning, but also precipitate to eliminate smoke, reduce temperature, and enable rescue personnel to enter the room without entering. Specifically, the metastable state active water has different physical and chemical property changes from ordinary water molecules, mainly including changes in oxidation recovery potential, viscosity, and dielectric constant. The jet of the temperature-activated water can be suspended around without being obstructed by sediment, without precipitation for a long time, and will not fall on the horizontal or vertical plane. The jet of the temperature-activated water can even float upward along the horizontal plane as much as possible, and separate a large amount of heat and combustible gas, and only a small amount of water is needed to effectively prevent heat radiation, and rescue personnel can approach the fire source to extinguish the fire wearing only ordinary combat uniforms. The above temperature activated water has no harm to the surrounding environment, greatly saves water compared with traditional fire extinguishing, is harmless to humans, animals and plants, and effectively protects the environment from pollution.

[0062] Furthermore, the unique physical characteristics make the temperature-activated water have three fire-extinguishing characteristics: first, the temperature-activated water can cool down the fire scene; second, the temperature-activated water can isolate the burning materials from oxygen and reduce the burning speed at the fire scene; third, the temperature-activated water evaporates into steam, which dilutes and reduces the oxygen content, further reducing the burning speed at the fire scene. Specifically, the temperature-activated water that floats for a long time fills the fire scene, and only in places where the gas or surface temperature exceeds 100°C, the temperature-activated water will form small bubbles. In other words, the temperature-activated water only forms bubbles on flames or various burning surfaces. Steam exists inside the bubbles, and when the bubbles are broken, the steam dilutes the air, reduces the oxygen ratio, and thus reduces the burning speed at the fire scene.
