Description

Technical Field

[0001] The utility model belongs to the technical field of fire fighting equipment, and in particular relates to an indoor water-based fire extinguishing device. Background Art

[0002] Every year, there are frequent fire-related casualties in China, which also brings huge economic losses. Among them, fires caused by high temperature weather and electricity and fire still account for a large proportion. For this reason, fire extinguishers are widely used. Fire extinguishers are a portable fire-fighting tool. Chemicals are placed in fire extinguishers. Different types of fire extinguishers have different ingredients. Fire extinguishers are usually stored in public places or places where fires may occur. They are designed for different causes of fire and are used to extinguish fires. There are many types of fire extinguishers. According to their mobility, they can be divided into: portable and cart-type; according to the power source of the fire extinguishing agent, they can be divided into: gas cylinder type, pressure storage type and chemical reaction type; according to the fire extinguishing agent filled, they can be divided into: foam fire extinguishers, dry powder fire extinguishers, carbon dioxide fire extinguishers and water-based fire extinguishers, etc.

[0003] There are two containers in the foam fire extinguisher, each containing two liquids, aluminum sulfate and sodium bicarbonate solution. The two solutions do not touch each other and do not undergo any chemical reaction. When a foam fire extinguisher is needed, turn the fire extinguisher upside down, and the two solutions mix together to produce a large amount of carbon dioxide gas. In addition to the two reactants, some foaming agents are also added to the fire extinguisher. Turn on the switch, and foam will spray out from the fire extinguisher, covering the burning objects, isolating the burning materials from the air, and lowering the temperature to achieve the purpose of extinguishing the fire.

[0004] The dry powder fire extinguisher is filled with dry powder fire extinguishing agent. Dry powder fire extinguishing agent is a dry and easy-flowing fine powder used for fire extinguishing. It is composed of inorganic salts with fire extinguishing efficiency and a small amount of additives that are dried, crushed and mixed into fine solid powder. It mainly uses compressed carbon dioxide to blow out dry powder (mainly containing sodium bicarbonate) to extinguish fire.

[0005] The bottle of the carbon dioxide fire extinguisher stores liquid carbon dioxide. When working, when the pressure handle of the bottle valve is pressed, the internal carbon dioxide fire extinguishing agent will be sprayed out from the siphon through the bottle valve to the nozzle, causing the oxygen concentration in the combustion area to drop rapidly. When the carbon dioxide reaches a sufficient concentration, the flame will suffocate and go out. At the same time, since liquid carbon dioxide will vaporize rapidly and absorb a large amount of heat in a very short time, it will have a certain cooling effect on the burning materials and also help to extinguish the fire.

[0006] The extinguishing agent in water-based fire extinguishers is mainly clean water. Water has low viscosity, high thermal stability, high density and high surface tension at room temperature. It mainly relies on cooling and suffocation to extinguish fire. The extinguishing agent in water-based fire extinguishers is mainly clean water. Water has low viscosity, high thermal stability, high density and high surface tension at room temperature. It mainly relies on cooling and suffocation to extinguish fire. Because every kilogram of water can absorb 2593.4KJ of heat when heated from room temperature to boiling point and completely evaporated and vaporized. Therefore, it uses its own ability to absorb sensible heat and latent heat to play a cooling and fire-extinguishing role, which is unmatched by other fire extinguishing agents. In addition, the water vapor formed after water is vaporized is an inert gas, and its volume will expand by about 1700 times. When extinguishing a fire, the water vapor generated by water vaporization will occupy the space in the combustion area, dilute the oxygen content around the burning object, hinder fresh air from entering the combustion area, and greatly reduce the oxygen concentration in the combustion area, thereby achieving the purpose of suffocation and extinguishing fire. When water is sprayed in a mist, the specific surface area of ​​the water droplets and mist droplets formed will be greatly increased, which will enhance the heat exchange between water and fire, thereby strengthening its cooling and suffocating effects. In addition, it can also dilute some flammable and combustible liquids that are easily soluble in water; the water mist produced by the strong jet can emulsify the flammable and combustible liquids, rapidly cool the liquid surface, and reduce the rate of combustible vapor generation to achieve the purpose of extinguishing the fire. Water-based fire extinguishers are widely used because of their ease of use and low cost.

[0007] Indoor pipe network fire protection systems are generally installed with the early construction of buildings. Some buildings are not installed in the early stage. If they are installed later, the cost will be high and the maintenance will be complicated. For a 20 square meter inhabited room, due to limited space, it is not suitable for large fire extinguishing devices, nor is it suitable for the later installation of pipe network fire protection systems. Some small fire extinguishing devices such as about 30 liters are not suitable for room use because they occupy a large space in the room and affect the cleanliness and aesthetics of the room. Therefore, it is necessary to provide an indoor fire extinguishing device that can extinguish the flames as soon as possible after a fire occurs indoors. Utility Model Content
