It refers to an effective fire extinguishing method and fire extinguishing device composed of powdered fire extinguishing agent and mixed with high pressure water for fire extinguishing. [Background Art] In the past, fires in general houses or buildings (commonly known as A fires) were usually extinguished by water spraying, but at this time, a large amount of water had to be used, and it was also time-consuming. Often, the burning area was gradually increased. Increased, making firefighters and other personnel engaged in fire fighting work must be in a dangerous state for a long time. In addition, in order to completely extinguish the fire and prevent reburning, a larger amount of water must be sprinkled, which results in the loss of a larger amount of water and a secondary disaster other than the affected object. There will be problems of insufficient fire fighting water. In addition, in the case of oil and gas fires (commonly known as B fires) such as dangerous goods manufacturing plants or oils, powder fire extinguishing agents or foam fire extinguishing agents are generally used to extinguish fires. The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs prints the well-known that powder fire extinguishing agents have the effect of suppressing re-ignition. Once powder fire extinguishing agents are spread radially on combustibles, especially the object of general fires-wood for buildings, etc. It penetrates into the wood and forms a glassy film on the surface by heat, which has the effect of preventing the flame from igniting and suppressing re-ignition. Foam fire extinguishing equipment uses the cooling effect of aqueous solution and the effect of isolating air from foam to extinguish fires, but it must have a large amount of water and take a long time to control the flame. In addition, most of the fire extinguishing in tunnels or caves currently uses foam extinguishing agents to extinguish fires; however, foam is easy to be scattered by the hot wind of the fire ____ 4 This paper size applies to China's national standard (CNS) A4 specification (21〇 Χ 297 mm) '' 1241202 A7 'B7 V.

Description of the invention () Best Mode] The following is a description of the present invention with reference to the drawings The embodiment is an example view of a fire extinguishing device of the present invention is related to fire fighting equipment described in FIG loading. In the figure, the highway fire hydrant (1) sends the fire fighting water to the fire truck (3) through the water pipe (2), and the fire fighting water is reused by the pump (4) of the fire truck to pressurize. Then, through a mixer, such as a powder fire extinguishing agent mixer (8) owned by a Venturi tube (a device for measuring liquid flow) (or a surfactant blender (6)), Proportionally add the powder fire extinguishing agent (or the surface active agent stock solution) in the powder fire extinguishing agent container (7) (or the surface active agent container (5)), mix it into the aforementioned pressure, and send it into the fire extinguishing water pressure. In the pressurized water in the delivery pipe, the mixed liquid (11) passes through the fire-fighting water pipe (9), is sprayed from the radiation nozzle (10), and sprinkles water on the dwelling house under fire. The basic technical idea of the present invention is to add and mix powder extinguishing agent in pressurized water. Both the fire extinguishing effect of water and the fire extinguishing action of powder extinguishing agent can be applied at the same time, and at the same time, water (pressurized water) is used as the transportation medium of powder extinguishing agent. In order to improve the fire extinguishing efficiency, the addition and mixing ratio of powder fire extinguishing agent is 500 ~ 200L / min relative to the amount of water, and the powder fire extinguishing agent content rate is 5 ~ 25% by weight as an ideal ratio. The fire extinguishing powder medicament used in the present invention can be a commonly known product, but powder fire extinguishing medicament containing ammonium primary phosphate or potassium bicarbonate as a main component is particularly favored. For example, the composition of the first ammonium phosphate (NΗ4Η2PO4), which is the so-called ABC powder fire extinguishing agent, is shown in Table 1. That is, the first ammonium phosphate accounts for 45 to 90%, and the ammonium sulfate is less than 45%. The other components include a certain amount of a consolidation preventive agent and a water-repellent agent, and the coloring agent is extremely small. In addition, the specific gravity of the powder is about 1.8. 11 This paper size applies to China National Standard (CNS) A4 specification (210X297 mm) 4--1, ----- Φ -------, 玎 ------ Φ, (please first Read the notes on the back and fill in this page) 1241202 Λ7 ___ B7 V.

Description of the invention () The situation of film bubble fire extinguishing has been shortened by about 20%. In the fire extinguishing time, it is about 1/4 of the fire extinguishing with water film bubble. Therefore, the method of the present invention can achieve the goal of completing assembly and fire suppression in a very short time. B. Radiation distance comparison experiment: The second is the comparison experiment about radiation distance. The results are shown in Figure 11 ~ Figure 13. As a result, the reason is not explained clearly, but the radiation distances of WD and FD are longer by 1.2 to 1.25 times than when only water or water-based membranes are bubbled. [Possibility of industrial use] In the conventional fire extinguishing method, it took a considerable amount of time to suppress the flame during combustion. However, the fire extinguishing device of the simple constitution device of the present invention can greatly shorten the assembly time and the fire extinguishing time. In particular, in order to use powdered fire extinguishing agent as a conveyance medium for powder fire extinguishing agent, the powdered fire extinguishing agent is added to the pressure feeding water, and the fire extinguishing with water and powder fire extinguishing agent can be performed at the same time to achieve high efficiency fire extinguishing. In addition, the radiation distance is greatly increased compared to using only pressurized water, so the fire extinguishing ability can be improved. As a result, for example, the chances of firefighters to rescue victims trapped in a fire are increased. In addition, in terms of economic benefits, the amount of water used for fire suppression has decreased sharply, the number of fires sprayed with water other than the disaster-stricken objects has been reduced twice, and the number of firefighters, firefighting materials, and firefighting equipment has been significantly reduced. 26_ ^ The paper size applies to the Chinese National Standard (CNS) A4 (2l " 〇297297 mm) —1 ---.------ 0!
