本发明的工作原理: 通过对输送系统的控制, 水进入消防泵获取喷射动力, 预混液按 比例吸入比例混合器与水混合。 气瓶组内的高压氮气经减压阀进入干粉罐, 使千粉获取喷 射动力。 水、 预混液与干粉可通过对输送系统中控制阀的控制, 进行单独调控按需获取喷 射动力, 进入喷射系统, 喷射系统既可单独喷射一种灭火剂, 又可同时喷射两种及两种以 上灭火剂组合。 从而实现了车载高喷多剂联用灭火装置既可单独喷射一种灭火剂, 也可同 时喷射两种或两种以上灭火剂组合的功能。  The working principle of the invention: Through the control of the conveying system, the water enters the fire pump to obtain the injection power, and the premixed liquid is mixed with the water in proportion to the proportional mixing mixer. The high-pressure nitrogen gas in the gas cylinder group enters the dry powder tank through the pressure reducing valve, so that the powder can obtain the injection power. Water, premixed liquid and dry powder can be controlled by the control valve in the conveying system, and can be separately controlled to obtain the injection power and enter the injection system. The injection system can spray two kinds of fire extinguishing agent separately, and can spray two or two at the same time. The above fire extinguishing agent combination. Therefore, the vehicle-mounted high-spray multi-agent fire extinguishing device can be sprayed with one fire extinguishing agent alone or with two or more fire extinguishing agent combinations at the same time.
与已有技术相比, 本发明的有益效果体现在:  Compared with the prior art, the beneficial effects of the present invention are embodied in:
1、 实现了可单独喷射一种灭火剂, 也可同时喷射两种或两种以上灭火剂组合。 改变 了传统高喷消防车的灭火功能, 满足了不同火灾类型对灭火战术的需求。 本发明集车载、 灭火于一体, 不仅具有广谱灭火作用, 而且具有灭火剂用量少, 灭火速度快, 灭火后抗复 燃效果好及环保等多项优势。  1. It is realized that one fire extinguishing agent can be sprayed separately, or two or more fire extinguishing agent combinations can be sprayed at the same time. The fire-fighting function of the traditional high-spray fire truck has been changed to meet the demand for fire-fighting tactics of different fire types. The invention integrates the vehicle and the fire extinguishing into one, not only has the broad-spectrum fire-extinguishing effect, but also has many advantages such as less fire extinguishing agent dosage, fast fire extinguishing speed, good anti-reburning effect after fire extinguishing and environmental protection.
2、 利用流体力学的射流附壁作用, 可将新型、 高效、 抗复燃预混液与水混合后同步 抵达燃烧表面, 水有强力的冷却作用, 炽热的燃烧表面将水气化, 形成的水蒸气不仅具有 很大的潜热量, 而且可大幅度降低可燃气体在燃烧区内的百分比浓度; 同时, 微胞囊灭火 剂具有强力的冷却作用, 可快速降温, 有利于灭火。 因此具有灭火剂用量少, 灭火速度快, 灭火后抗复燃效果好以及环保等优势。 2. Using the hydrodynamic fluid-attached wall effect, the new, high-efficiency, anti-reburning premixed liquid can be mixed with water and then arrive at the combustion surface synchronously. The water has a strong cooling effect, and the hot burning surface vaporizes the water, forming water. The steam not only has a large potential heat, but also can greatly reduce the percentage concentration of the combustible gas in the combustion zone; at the same time, the microcyst extinguishant has a strong cooling effect, can quickly cool down, and is beneficial to fire extinguishing. Therefore, the amount of fire extinguishing agent is small, and the fire extinguishing speed is fast. After fire extinguishing, it has good anti-reburning effect and environmental protection advantages.
3、 以高速水流为载体, 可同时将水及按比例的新型、 高效、 抗复燃预混液从比例混 合器中吸入, 配以憎水型超细干粉从臂架顶部的喷射炮或车箱内的喷射枪进行中远距离的 喷射, 直达燃烧区。 由于喷出的灭火剂为多剂组合式, 所以它兼具多种灭火剂的优点, 是 目前任何单一一种灭火剂所不能比拟的, 是真正意义上的卤代烷替代技术。 不仅具有灭火 剂用量少, 灭火速度快, 灭火后抗复燃效果好以及环保等优势, 而且具有全方位、 广谱灭 火效应, 可扑灭 A、 B、 C、 D、 E 、 F类火灾. 大大提高了灭火性能。  3. With high-speed water flow as carrier, water and proportional new, high-efficiency and anti-reburning premixed liquid can be sucked from the proportional mixer at the same time, with water-type ultra-fine dry powder from the spray gun or the inside of the frame at the top of the boom. The spray gun performs medium to long range jets and reaches the combustion zone. Because the fire extinguishing agent is a multi-agent combination, it has the advantages of multiple fire extinguishing agents, which is unmatched by any single fire extinguishing agent. It is a true halogenated alkane replacement technology. It not only has the advantages of low dosage of fire extinguishing agent, fast fire extinguishing, good anti-reburning effect after fire extinguishing and environmental protection, but also has all-round and broad-spectrum fire extinguishing effect, which can extinguish A, B, C, D, E and F fires. Greatly improved fire performance.
4、 粒径不大于 15 y m的千粉称为超细干粉, 以 "气 -粉"射流的方式将超细干粉灭 火剂射出, 形成冷气溶胶灭火剂射流。 冷气溶胶的密度与空气接近, 具有可压缩性、 流动 性、弥散性等气体灭火剂的典型特点,在高层建筑中,可快速弥漫至室内有限空间产生"全 淹没"的灭火效果, 使火焰在极短时间内熄灭; 可代替补充气流进入隧道、 古建筑等复杂 空间内将其中的大火扑灭。 以惰化浓度将冷气溶胶灭火剂射入泄漏出的可燃性气体中时, 可以抑制爆燃爆轰的发生。  4. The powder with a particle size of not more than 15 y m is called ultra-fine dry powder. The ultra-fine dry powder extinguishing agent is sprayed by the "gas-powder" jet to form a cold aerosol fire extinguishing agent jet. The density of cold aerosol is close to that of air. It has the typical characteristics of gas fire extinguishing agent such as compressibility, fluidity and dispersion. In high-rise buildings, it can quickly diffuse into the limited space of the room to produce a "full flooding" fire extinguishing effect. It is extinguished in a very short time; it can be used to replace the supplementary airflow into the complex space such as tunnels and ancient buildings to extinguish the fire. When the cold aerosol fire extinguishing agent is injected into the leaked flammable gas at an inerting concentration, the occurrence of deflagration detonation can be suppressed.
5、 超细干粉灭火后几乎无散落物, 少量沾附在炽热表面, 成玻璃状覆盖层极易清除。 附图说明:  5. After the ultra-fine dry powder is extinguished, there is almost no scattered material, and a small amount of it adheres to the hot surface, and the glass coating layer is easy to remove. BRIEF DESCRIPTION OF THE DRAWINGS:
