Aerosol Fire Extinguisher

Abstract

This invention relates to a fire extinguisher that enables the application of a fire-extinguishing agent in aerosol form. The invention develops a fire extinguisher with a combustion chamber structure and a compatible body structure that increases the volume of the combustion chamber in which the active substance, which produces the aerosol particles that suppress the fire, is burned to form these particles, while maintaining the pressure resistance of the combustion chamber. Thanks to this polygonal combustion chamber, a larger quantity of active substance can be reliably used with this fire extinguisher. A detonator, which ensures the uniform combustion of the active substance even under adverse environmental conditions, is also described within the fire extinguisher.

Description

1 TARIFF Aerosol Fire Extinguisher Technical Area This invention enables the application of a fire extinguishing agent in aerosol form. It relates to a fire extinguisher. 5 Previous Technique Especially in order to control fires in their initial stages before they spread. Fire extinguishers are used. Aerosol fire extinguishers use a gas and this gas an aerosol consisting of suspended solid particles, especially during combustion by preventing the chain reaction of the released elements and removing heat from the environment 10 It has an effect. Aerosol fire extinguishers essentially consist of an outlet with relatively low pressure resistance. a closed combustion chamber containing combustion points, located inside the combustion chamber and combustion resulting in an active ingredient that forms the solid components of the aerosol and the active ingredient It consists of a fuse that enables it to ignite. A common type of match head fuse is 15. These devices, called detonators, are used. When the detonator is ignited, the active ingredient is burned. Because the combustion chamber is closed, the aerosol components released as a result of combustion are highly sensitive. They reach certain temperatures, and the compounds that will form the solid part of the aerosol are initially in gaseous form. It is released and distributed homogeneously within the combustion chamber. Inside the combustion chamber When the pressure exceeds the strength of the outlets, the outlets open, releasing the hot gas mixture. 20 The mixture is expelled from the combustion chamber. During this process, it cools due to the effect of expansion. Inside, small, evenly distributed solid particles form, creating an aerosol. This occurs because the mixture is brought to a high pressure before exiting the combustion chamber. In addition to obtaining the particle size, the aerosol is effectively released into the environment. It also enables distribution. 25 The solid particles in the aerosol have sizes of 10 µm and below. Thus, solid The particles can remain suspended for a long time. This can disrupt the combustion process. and the likelihood of the fire reigniting is reduced. 2 Aerosol fire extinguishers commonly have cylindrical combustion chambers. In documents numbered CN107670206A, RU2462283C1, RU2205673C1 and CA2838513A1 Cylindrical aerosol fire extinguishers are shown. In addition, it has a larger combustion chamber volume compared to cylinders of similar dimensions. aerosol 5 in the shape of a rectangular prism that allows the use of more active ingredients Fire extinguishers are also available. However, the rectangular prism shape, with its angled edges... Because it is less resistant to pressure than its cylindrical form, the outlet Besides the tearing points, there is also a possibility of tearing at the edges, and the full advantage of the volume is lost. It is not available for use as such. Brief Description of the Invention 10 With this invention, an active substance that gives rise to fire-suppressing aerosol particles can be used in this way. by increasing the volume of a combustion chamber in which particles are burned to form, a combustion chamber structure in which the pressure resistance of the combustion chamber is also maintained and compatible with it A fire extinguisher with a shell structure has been developed. This combustion chamber has a polygonal cross-section. Thanks to this invention, a larger amount of active ingredient can be reliably supplied with the fire extinguisher. 15 It can be used in this way.

The active ingredient (5) is compressed in a block or easily broken down by factors such as heat and pressure. It may be in the form of powder or granules packed in a biodegradable casing. Active ingredient 20 (5) formed a chain reaction by decomposing elements under the effect of the fuse (6). from a single compound or a mixture of more than one compound, one of which is an oxidant It may occur. The fuse (6) is activated as a result of the detection of fire signs. Fire signs are a The fuse (6) can be activated automatically by being detected by the system, as well as the fire 25 4 a manually triggered system as a result of its symptoms being observed by an observer It can also be operated by. When the fuse (6) is activated, the active substance (5) burns. components or their precursors that suppress fire when in solid state, when they burn It is formed in gaseous form due to the high temperatures generated inside the combustion chamber (3). Combustion When the pressure inside the chamber (3) reaches the level that will open the outlet points (4), this 5 Compounds are sprayed into the environment. During spraying, the pressure drops. The compounds produced, or their precursors, also cool down to become particles with a diameter of at most 10 µm. It forms an aerosol containing... The detonator (6) is connected to the detector or system that enables its operation via a cable (7). It is connected. The cable (7) is used both to maintain the pressure in the combustion chamber (3) and to ensure effective 10 (5) In order to protect the substance from elements such as humidity in the environment before use It is attached to the body (2) by means of a leakproof connection element (8). The exit points (4) are covered with a membrane that tears under the pressure generated during use. The durability of the membrane, the effective use of the aerosol in the environment where the fire extinguisher (1) is used It is designed to ensure effective dispersion. Effective dispersion of the aerosol, spraying 15 speed, and therefore inside the combustion chamber (3) before the rupture of the exit points (4). This depends on creating the pressure that will allow the aerosol to be sprayed at a sufficient speed. According to this, the dimensions of the usage area, the type of fire expected in the usage area, and the type of fire used... The active ingredient (5) can be designed taking into account variables such as type and amount. The fire extinguisher (1) must be positioned appropriately within its area of ​​use and 20 It also includes a foot (9) that enables its orientation. The foot (9) is preferably attached to the body (2), It is attached to the body (2) at one point on each of the two parallel side surfaces. During the combustion of the active substance (5), the temperature may damage the combustion chamber (3) or the exit points (4) before the desired level of combustion of the active substance (5) To prevent it from reaching a level that would exceed 25 in the combustion chamber (3). Temperature regulating elements or factors (10) are also present. Temperature regulating element or elements (10) should limit the volume of the combustion chamber (3) to a minimum, combustion chamber (3) It should not obstruct the flow of gases inside and efficient heat transfer with the environment inside the combustion chamber (3). It must have a large surface area to perform this function. For this, it needs something like a sponge. a temperature regulating element in a porous structure (10) or a large number of beads or similar 30 Temperature regulating elements (10) in the form of can be used. Temperature regulating element or elements (10), made of natural stones, ceramics or suitablely moldable and It may be made from another material that can draw heat from the environment. Pressure during combustion or after exceeding the exit points (4) Temperature regulating element or elements (10) combustion chamber 5 in response to changes and gas flow In order to maintain their positions inside (3), support plates are also placed inside the combustion chamber (3). Support plates can be found in a structure that will restrict gas flow as little as possible, for example. It has a perforated structure. The subject of the invention is a fire extinguisher (1), one of its bases has outlet points (4) on it. The inner 10 consists of an exit surface (11) located and perpendicular to the intended eruption direction. a right prism with a polygonal base where all angles are obtuse angles It includes the combustion chamber (3) in the form of a temperature regulating element or elements (10). If present, the cross-sections of the support plates perpendicular to the targeted spray direction and combustion. The cross-sections of the chamber (3) perpendicular to the targeted spray direction do not overlap. Combustion the perimeter of the room (3) and the temperature regulating element or elements (10) and support plates if any 15 The spaces between them form channels that allow gas to flow. Thus, the cylinder It offers both volumetric advantages compared to its shape and compressive strength advantages compared to a rectangular prism. It has been possible to provide. The fuselage (2) is compatible with the combustion chamber (3), the combustion chamber (3) It is in the form of a right prism with a surrounding polygonal base. This gap is 20 degrees between the temperature regulating element or elements (10) and the cross-section of the support plates, if any. It can surround it from all sides. In a preferred application of the invention, the cross-section of the combustion chamber (3), It is in the shape of a hexagon with two opposite corners having interior angles of 150 to 170°, preferably 165°, Cross-section of the temperature regulating element or elements (10) and, if any, the support plates, combustion chamber (3) is designed to create voids corresponding to the aforementioned corners of the section. For this purpose The cross-section of the temperature regulating element or elements (10) and, if any, the support plates, e.g., 25 a cross-section of the combustion chamber (3) extending between the edges that are not adjacent to the aforementioned corners rectangular in shape or overlapping except for the corners referred to as the combustion chamber (3) cross-section It can be octagonal in shape. In order for the body (2) to be supported at two points by one foot (9), preferably the polygon mentioned At least two of its sides are parallel to each other. 30 6 Ease of production and a wide flat surface on which the leak-proof connection element (8) can press. For this purpose, the polygon in question is preferably a hexagon. The leakproof connection element (8) A flat surface to stand on can only be achieved at the base of a cylindrical body. However, a sealed connection point at the base of the fuselage enables installation in confined spaces. It restricts. 5 With the fire extinguisher (1) which is the subject of the invention, thanks to the expanded volume of the combustion chamber (3), Burning of a larger amount of active substance (5) before exceeding the exit points (4) This is possible. Thanks to the increased pressure resistance of the combustion chamber (3), the outlet can also be provided. the aerosol must be effectively sprayed into the environment before exceeding points (4) The high pressures required can be obtained safely. 10 The subject of the invention is the fire extinguisher (1), thanks to its polygonal prism shape, the active substance (5) It can maintain its reliability and effectiveness even when burning irregularly. Aerosol fire extinguishers (1) release the active substance (5) that is ignited by the fuse (6) onto the outlet surface. (11) Although they are designed to burn from the side looking at, the active ingredient (5) Due to the pores within it, burning can also occur in an uneven manner. 15 Thanks to the gaps, in this case the uneven distribution of pressure inside the combustion chamber (3) is also prevented. This can be prevented. Thus, the effectiveness of the aerosol is reduced due to the compression of the released gas. to prevent the fire extinguisher (1) from being unable to spray and even from exploding. It is possible to pass through. In one application of the invention, a curve enclosing the exit points (4) on the exit surface (11) 20 There is a slit (12) that runs along the entire length. The pressure inside the combustion chamber (3) is sufficient. When it reaches the exit points (4), the aerosol is sprayed from the slit (12) as well as the exit points, It can be effectively spread throughout the environment. On the slit (12), the parts of the exit surface (11) that are inside and outside the slit (12). There is also at least one slat (13) that fastens them together. The slats (13) are used in normal operation 25 will break under forces above the force acting on the exit surface (11) during the process It is of a nature. If the pressure inside the combustion chamber (3) reaches dangerous levels, the slats (13) breaks and the part of the exit surface (11) remaining inside the slit (12) opens up, releasing the aerosol. This allows for evacuation. Thus, if the exit points (4) are not opened 7 even aerosol can be sprayed into the environment and the possibility of the fire extinguisher (1) exploding This is being prevented. The slit (12) preferably does not form a closed curve and the exit surface (11) is inside the slit (12). and the parts outside are connected to each other in one area. Thus, the slats (13) In case of fracture, the part of the exit surface (11) that remains inside the crack (12) is the region mentioned 5 It is not launched along with the aerosol that is held and sprayed by the hand. The subject of the invention is an aerosol fire extinguisher (1), the active substance (5) can be precisely determined when desired to ensure that it can be burned and that the active substance (5) burns regularly To assist, it includes an improved fuse (6). According to the invention, the fuse (6) is a fuse The fuse body (14) contains a wire inside the fuse body (14) and is connected to an electrical source, fuse 10 a pyrogen mixture located inside the body (14) and activated by the action of the wire, and Sparks generated as a result of the activation of the igniter mixture are directed at the active substance (5) It contains two spark holes (15) that allow the fire to reach the fire extinguisher (1). Even if it has been left in adverse environmental conditions, this fuse (6) produces a strong spark and is effective This ensures that the substance (5) is burned as expected. 15
