With mixed sprinkler It relates to the fire truck (100).

Class A fires, which are general fires that occur in buildings in urban areas, are combustible materials combustible and fires that leave ashes after combustion such as wood, paper and synthetic resins such as plastics, plastics, rubber and fibers. Forcible disaster prevention requires artificially blocking the principle of physical and chemical combustion, lowering the combustion temperature, removing flammables from the fire, or suppressing the combustion chain reaction such as stopping the supply of oxygen.

In general, water is the most used fire extinguishing agent used in Class A fire prevention. The reason why water is widely used is easy to obtain, and because of the high specific heat and latent heat of evaporation, it has excellent cooling effect and can be transported through pump and pipe. It is easy to convert into high pressure water by pump operation, and the water discharged from the nozzle can be sprayed in the form of rods and various forms.In general, the fire fighting water, which is a fire fighting agent, is converted to high pressure in order to extinguish the fire. Spray through fire in the form of rods. In the existing fire extinguishing method, when the water directly touches the fire part, the extinguishing efficiency is high, and it acts as a disaster prevention effect by cooling the fire part and blocking the air around the combustible material. When water changes to water vapor at 100 ° C, the volume increases by about 1600 times and replaces or dilutes the air at the fire site, resulting in a suffocation effect. The water vapor generated at the fire site prevents combustion. However, when the water escapes from the fire or falls to the floor, there is a problem that the disaster prevention effect is lost.

On the other hand, due to the nature of the fire space, structures or walls. When obstacles appear in the column, the water stream is sprayed in the form of a rod, so the obstacle rear surface has a serious problem that the disaster prevention effect by the water column sprayed into a square against the spray of fire water is hampered.

In such a poor fire place, firefighters have to move the nozzle to the blind spot in order to extinguish the fire on the rear surface of the obstacle, and the firefighters are exposed to many dangers. In addition, in the case of a small space inaccessible to disaster prevention personnel, a fire in a pipeline such as a manhole, or a fire in an elevator moving space, there was a limit to disaster prevention using such fire space only by using fire water.

Hereinafter, a description will be given of the operation of the watering fire truck including a mixture for fire protection and mixed watering apparatus according to an embodiment of the present invention.

First, when the fire protection mixture is sprayed through the discharge nozzle, a large number of bubbles are formed in the fire prevention mixture by the pressure difference with the outside, and is sprayed by directly expanding or indirectly contacting the fire part in an expanded state. The fire extinguishes as it touches, and the air bubble is filled artificially in a short time (several seconds, minutes, tens of minutes), and the indirect fire suppression effect is brought about. In the same way as above, if you extinguish fires in different directions at the same time, the volume of bubbles does not disperse and meets the bubble walls coming in from nearby, forming a huge wall of bubbles in an instant to completely fill the enclosed space. Very advantageous. It also reduces the area of fire by compressing the fire space while preventing the spread of fire. As a result, complete disaster prevention time can be reduced.

Next, a description will be given of the operation of the watering fire truck including a mixed watering device.

First, the high pressure fire water is supplied from an external water hydrant or a fire water storage tank of a fire truck equipped with a water supply tank through the water supply connecting portion shown in FIGS. 4 and 5. The first mixture and the second mixture stored in the first mixture tank and the second mixture stored in the second mixture tank are mixed with the fire water through the primary mixer and the second mixer in the fire water thus supplied, and are supplied through the pressurizer from the third mixture tank. Tertiary mixture is further mixed in a tertiary mixer. In this case, the mixing ratio of each mixture can be adjusted by adjusting the primary mixture control valve, the secondary mixture control valve and the tertiary mixture control valve. The fire prevention mixture thus mixed is controlled through the discharge control valve and sprayed through the discharge nozzle.

On the other hand, as shown in Figure 4, each mixed sprinkling device to adjust the mixing ratio and the discharge flow rate of each mixture for each mixed sprinkler differently, even at a single fire site to have a mixture for fire prevention disaster Can spray at the same time. For example, according to the fire conditions of the site as shown in FIG. 4, the first mixed sprinkler uses only water, the second mixed sprinkler uses only water and liquid co2, and the third mixed sprinkler Or mix with primary and water. In addition, by mixing liquid CO₂ or mixing both primary and secondary mixtures and liquid CO₂, the mixing ratio of each mixture can be easily adjusted using the mixing control terminal. It is possible to adjust and control according to the fire conditions of the site, so that effective fire suppression is possible. In other words, where the flames of fire are strongly blown out, the amount of fire water is increased, and when a fire or the like is blocked by filling a space or a passage with a bubble, the mixing ratio of the mixture is controlled so that many bubbles are generated. It is possible to respond appropriately and variously in various fire suppression situations that can occur at one fire site.
