Fire extinguisher

Technical field

The technical solution concerns fire extinguishers, both complex and individual units.

BACKGROUND OF THE INVENTION

Existing devices use in most cases a complicated system of spraying extinguishing agent, where under pressure the liquid extinguishing agent is sprayed into the space by means of nozzles so that it changes into a gas in the environment as quickly as possible and then extinguishes the fire.

In cold environments or imperfect spraying of liquid, 100% gasification of the extinguishing liquid does not occur, thus reducing the extinguishing efficiency and at the same time extinguishing liquid droplets, which do not gasee in contact with fire, create hazardous chemicals such as ) and carbonyl halides (COX2).

A further disadvantage of these extinguishing devices is that the extinguishing is costly and time-consuming, with the longer extinguishing time being proportional to the formation of the above undesirable chemical products.

SUMMARY OF THE INVENTION

The aforementioned drawbacks are largely eliminated by the modification of the fire extinguishing devices, which consists in the fact that the fire extinguishing system comprises a device for preheating the extinguishing agent. The location of the preheating device can be anywhere where it acts to heat the extinguishing agent. This ensures a higher temperature of the extinguishing liquid and thus achieves faster atomization of the liquid and its gasification in case of fire. Because the extinguishing liquid is pre-heated, it gasses faster when spraying, thus avoiding undesirable chemical products. This gasification method allows direct application to the protected area without the need for spray nozzles, thus significantly reducing the time for flooding and fire suppression. This method can also be used for fire extinguishing, especially in cases where the supply of new air cannot be prevented (eg in motor parts with a fan)

DETAILED DESCRIPTION OF THE INVENTION

Example 1

The extinguishing medium is placed in a tank with extinguishing liquid

Example 2

The extinguisher preheater device is located in / or upstream of the spray nozzle.

Example 3

The extinguishing device is placed in a line with extinguishing liquid.

Industrial applicability

This technical solution is applicable to all fire extinguishing systems using a liquid which extinguishes into a gas during extinguishing.

Claims (1)

1. Extinguishing equipment using to extinguish a liquid and convert it into a gas, characterized in that the extinguisher or system has at least one extinguishing liquid preheater located in or directly in the extinguishing liquid tank and / or in the spray nozzle, and / or in a conduit for conducting fluid from the tank to the nozzle.
