Definitions
- the invention relates to a device for extinguishing fire and for preventing the emergence and / or spread of fire, consisting of - a pressure-resistant container for receiving one from one
- a trigger mechanism by the actuation of which the extinguishing agent can be driven out of the container under the action of a propellant via the riser pipe and the device connected to it.
- Such devices for extinguishing fire are known, for example, as water extinguishers, powder extinguishers or foam extinguishers, the water extinguishers containing only water as the extinguishing agent, but which has the worst extinguishing effect due to the rapid evaporation and often leaves a very large amount of water damage.
- the powder extinguishers are more effective than water extinguishers, but they also cause great damage, especially to sensitive electrical and electronic devices, even in areas away from the source of the fire, because the dust-fine powder spreads quickly over long distances.
- a particular disadvantage of the powder extinguisher is that the powder has to be disposed of at high cost because of the risk of environmental pollution and has to be incinerated as hazardous waste. There is also a risk that the powder will enter the sewage system when it rains and contaminate rivers and lakes.
- an extinguishing device which is designed as a foam hole that works with a premixed solution, that is, that the foam agent already when filling with the
- the water, powder or foam extinguishers known to date have the disadvantage that the extinguishing agent evaporates quickly and does not retain the radiant heat emitted by a source of fire and cannot prevent an apparently extinguished fire from reigniting. Particularly when the walls are standing essentially vertically, the extinguishing agent flows down or slides down immediately after impact and thus has practically no appreciable extinguishing effect. Therefore, it is also less suitable for preventive fire protection, since houses to be protected, for example, essentially only have vertical walls to which the extinguishing agent, at least in the required thickness, does not adhere, apart from the fact that the powder and the foam pass through that of a neighboring
- Radiation heat emanating from the source of the fire has evaporated in a short time.
- the invention has for its object to provide a device of the type mentioned, the
- Pollution covers a source of fire for a long time and cools down sustainably, does not allow any radiant heat to pass through, adheres to almost any thickness even on vertical walls and reliably prevents an extinguished fire from reigniting.
- the carrier from water, optionally with additives, preferably with an antifreeze, and the further component consists of a liquid dispersion which changes into the gel state by mixing with water.
- this transition takes place after actuation of the trigger mechanism by mixing with the water expelled by the propellant essentially within the riser pipe.
- the device consists of an extinguishing gun which is designed as a spray gun which uniformly distributes the gel over the largest possible area.
- the device consists of a pipe system which has numerous outlet openings, which than the gel have a The largest possible area is formed by uniformly distributing spray nozzles, the pipe system being attached to or in the ceiling of a room.
- the pipe system is attached to an aircraft or an airship according to claim 6.
- the trigger mechanism can be operated by hand or controlled by an automatically operating signaling system which responds to smoke and / or to excessive temperatures.
- liquid dispersion is added to the container when or after the container is filled with water and then the container is ready for use is closed, wherein according to claim 9, the liquid dispersion is contained in a water-soluble film bag which is added to the container when or after filling it with water.
- the liquid dispersion is contained in a vessel arranged inside or outside the container and only pours into the water after the triggering mechanism has been actuated, the vessel being connected to the riser pipe according to claim 11 and the After the trigger mechanism has been actuated, the dispersion pours into the water flowing through the riser.
- the liquid dispersion consists of sodium polyacrylate as the base material, to which further constituents such as terpolymer, water, paraffins, emulsifiers and activators are added.
- Compressed air cushion is arranged above the water or that the content of a high-pressure propellant bottle arranged inside or outside the container is used as the propellant, the propellant of which consists of carbon dioxide, nitrogen or compressed air.
- the extinguishing agent covers a source of fire for a long time and cools sustainably, does not allow any radiant heat to pass through, also adheres to vertical walls of almost any thickness and reliably prevents an extinguished fire from reigniting.
- Another advantage is that the extinguishing agent is completely soluble in water and can therefore be removed easily and in an environmentally friendly manner. Expensive disposal is not necessary because its substances do not have to be treated as special waste.
- Piling up itself corresponds to the process of spraying with foam from a foam hole.
- the key difference, however, is that the foam bubbles are filled with air, while the gel bubbles are filled with water. This water filling causes the excellent heat protection properties.
- the gel also has good adhesion properties, so that it can be applied to both vertical and horizontal surfaces such as walls, walls, roofs, ceilings and
- the source of the fire is quickly and effectively smothered and cooled due to the high cooling effect of the water-filled gel vesicles and their immediate adhesion to the fire material. Water consumption is drastically reduced. This results in significantly less water damage and, at the same time, less contaminated water. The costs of consequential damage from fire fighting are therefore significantly lower when using the gel than when using water.
- Another area of application is preventive protection against the occurrence or spread of a fire. Due to the special cooling properties of the gel Possibility, for example, to cover industrial plants, tanks and buildings with a low water consumption with a gel protective film.
- the advantage here is that this protective film dries after a certain time and can be easily removed in large pieces without damaging the protected areas.
- the use of the gel is also particularly advantageous when fighting forest and steppe fires, since effective fire aisles can be created with the gel, which reliably prevent the fire from spreading over the large gel area.
