Description

Portable environmental fire extinguisher

The invention belongs to fire extinguishing technology, in particular to a portable simple fire extinguisher.

The traditional fire extinguishers are mainly gas storage fire extinguishers, mainly filled with high-pressure chemicals and water in the gas cylinders of the fire extinguishers. When using the fire extinguishing device, remove the helmet of the fire extinguisher and use a tool to pierce the sealing piece on the gas cylinder. After the chemical is mixed with water, it can be fired through the nozzle.

This type of traditional fire extinguisher, after use, or beyond the use period, need to ship the fire extinguisher back to the manufacturer to replenish the chemical and repressurize before it can be used again. This process often takes a lot of time. Moreover, since the gas cylinder of the fire extinguisher needs to withstand high pressure, for safety reasons, the material of the gas cylinder is usually selected from carbon steel with a heavier weight, which increases production and transportation costs, and is inconvenient to use.

On the other hand, water-based fire extinguishers can only be used in general. If the fire source is grease, because the oil is lighter than water, the burning oil will easily float around the water, which will expand the fire area. Therefore, special fire extinguishers are required for fires where the fire source is grease, including light water foam fire extinguishers, dry powder fire extinguishers, carbon dioxide fire extinguishers, and halogenated fire extinguishing agents.

The light water foam fire extinguisher is a high-efficiency fire extinguisher suitable for extinguishing the initial fire of solids, oils, especially petroleum products. But not applicable to extinguish water-soluble flammable, flammable liquids and Electrical, light metal fires. The light water foam fire extinguisher is a light water foam fire extinguishing agent (ie, a water film forming foam fire extinguishing agent) and a compressed gas (nitrogen or compressed gas) are stored in the fire extinguisher cylinder, and the fire extinguishing agent is driven by the pressure of the compressed gas to be fired. The aqueous film-forming foam fire extinguishing agent is composed of a fluorocarbon surfactant and other additives. Since the fluorocarbon surfactant sharply reduces the surface tension of the aqueous solution, it can form a water film on the oil surface, which can effectively suppress the evaporation of the fuel, accelerate the flow speed of the foam, and quickly extinguish the fire.

Dry powder fire extinguishers are suitable for fighting fires in oils, petroleum products, organic solvents, flammable gases, and electrical equipment. The dry powder fire extinguishing agent is mainly composed of sodium hydrogencarbonate, potassium nitrate, mica powder and the like. The dry powder fire extinguishing agent sprays the misty dry powder from the fire extinguisher and covers the surface of the burning material, so that the chain reaction of combustion stops, and the burning cannot be continued. The advantage of dry powder fire extinguishing is high fire extinguishing efficiency, good insulation performance, no pollution to machinery and equipment after fire extinguishing, and it is not easy to deteriorate after long-term storage.

Carbon dioxide fire extinguishers are suitable for saving precious equipment, archives, instrumentation, electrical appliances below 600 volts and grease fires. Carbon dioxide gas is neutral, colorless, odorless, non-conductive inert gas, non-corrosive, but has certain toxicity. When the concentration of carbon dioxide in the air reaches 10% or more, people can die. Carbon dioxide is a gas under standard conditions and can be liquefied by compression and cooling, or it can become solid. The relative density of carbon dioxide is 1.529, which is heavier than air. After the liquid carbon dioxide becomes a gas, it is 760 times larger than the original liquid. Carbon dioxide gas can displace the air burning on the surface during fire fighting. When the concentration of carbon dioxide in the air reaches 35% or more, the combustion stops.

Halogenated alkane fire extinguishers are mainly used to fight fires from oils, electrical appliances, meters, books, archives and other valuables. Among the halogenated alkane fire extinguishing agents, difluoro-chlorobromomethane is a typical and high-performance fire extinguishing agent. It mainly acts as a cooling and suffocating effect through interference and inhibition of the chain reaction to achieve the purpose of fire extinguishing. Difluoro-chlorobromomethane does not corrode or contaminate various materials and electrical equipment in buildings, and the amount is small, the fire-extinguishing efficiency is high, and long-term storage is not easy to deteriorate. But by Difluorochlorobromomethane can destroy the ozone layer in the atmosphere, and halogenated alkane fire extinguishers have been gradually banned in most advanced countries.

In view of the development of the above prior art and the safety requirements of home use, the present invention provides a portable environmental fire extinguisher, which is light in weight, simple in operation, and easy to carry. The fire extinguishing agent is an environmentally friendly water-based material, which can not only extinguish oil for oil, but also not harm. Human body and environment.

The portable environmental fire extinguisher 1 according to the present invention comprises a metal can body 100, a flexible packaging bag 200, a valve body 300, a compressed gas 400, and a water-based environmentally-extinguishing agent 500.
