Description

A detonator for an ignition device of a solid aerosol fire extinguisher and an ignition device of a solid aerosol fire extinguisher containing the same

The present invention relates to an initiator for an ignition device of a solid aerosol fire extinguisher and an ignition device for a solid aerosol fire extinguisher. More specifically, it has excellent properties as an initiator, so that combustion can easily occur even with a small amount of heat energy, and can be easily purchased. By using an initiator containing industrial nitride screen that is easy to handle, it helps in stable combustion of the ignition agent, and even if the heat energy generated from the heating board of the ignition device is small, it can be sufficiently amplified to burn the fire extinguishing agent normally. It relates to an initiator for an ignition device of a solid aerosol fire extinguisher that can provide sufficient heat energy to optimize the operating performance of the fire extinguisher and an ignition device of a solid aerosol fire extinguisher containing the same.

Fire extinguishers used to extinguish fires can be classified into powder fire extinguishers, carbon dioxide fire extinguishers, halon and gas fire extinguishers, and solid aerosol fire extinguishers depending on the fire extinguishing agent charged inside.

Among these, a solid aerosol fire extinguisher refers to a fire extinguishing device that extinguishes a fire by detecting heat, smoke, or flame generated by a fire and automatically or manually emitting aerosol. Solid aerosol fire extinguishers quickly release fire extinguishing aerosol and fill the space quickly to extinguish fire with fire extinguishing aerosol, so they can be easily introduced even in places where it is difficult for general fire extinguishing devices to operate effectively, and are widely applied in practice.

Extinguishing fires using solid aerosol fire extinguishers is based on a new mechanism consisting mainly of combustion of the means (i.e. extinguishing agent) to form gaseous highly dispersed condensed products that have the property of extinguishing the flame by suppressing the chain reaction of combustion. do. That is, when the solid fire extinguishing agent is ignited and burned by the ignition means, the gas pressure generated causes the fire extinguishing component to pass through the cooling layer and be sprayed to the outside, thereby extinguishing the fire by blocking the causative agent of the fire. The aerosol formed by such combustion may exhibit fire extinguishing properties due to the presence of alkali metal ions therein. As a source of alkali metal ions in aerosols, potassium nitrate or a mixture of potassium nitrate and potassium perchlorate is commonly used.

If a fire breaks out in a space where a solid aerosol fire extinguisher is installed, electricity is instantly instantly supplied by the fire detection device, generating heat and flames from the heating wire of the ignition device. At this time, the generated heat and flame lack the thermal energy to combust the fire extinguishing agent, so ignition powder (ignition agent) must be present in order to combust the fire extinguishing agent normally. The heat and flame generated from the heating wire cause primary combustion of the initiator to generate a flame, and then the fire extinguishing agent is burned by the flame generated as the ignition powder burns to form an aerosol.

Ignition devices for solid aerosol fire extinguishers can be classified into electric and self-generating types.

The electric ignition device is a method of obtaining heat energy by operating the heater heating wire with sufficient power, and can combust the ignition powder by the heat energy of the heating wire and combust the fire extinguishing agent by the heat energy from the combustion of the ignition agent. In some cases, an initiator may be used to help ensure stable combustion of the ignition powder.

The self-generating ignition device used in a non-powered room utilizes the power generated by the self-generating device in a very short period of time, for example, a few milliseconds. However, there is a limit to the amount of power generated in a very short period of time by the self-generating device, so it is very difficult to operate the ignition device properly to properly burn the fire extinguishing agent using only the output of the self-generating device. Therefore, in order to burn the fire extinguishing agent, a catalyst is needed to amplify the thermal energy of the heating element that operates with instantaneous power generated from the self-generating device.

Patent Document 1 (Korean Patent No. 10-1212982) discloses a conventional solid aerosol fire extinguishing device (1) in which the ignition agent (3) in the ignition device (2) is stored in a bag (4) such as a normal non-woven fabric. is disclosed. However, since the flame generated when the ignition agent burns is not provided with directionality to direct the fire extinguishing agent 5, there is a risk that ignition of the fire extinguishing agent 5 may be delayed or incomplete.

In addition, Patent Document 2 (Korean Patent No. 10-2020584) discloses a body (6), an ignition agent (7) stored inside the body, a heating board (9) for burning the ignition agent, and a circumference of the body. A conventional solid aerosol ignition device (5) including a flame emission hole (8) formed in the portion is disclosed. This conventional solid aerosol ignition device 5 can direct the flame toward the fire extinguishing agent and promote ignition of the fire extinguishing agent.

However, according to Korean Patent No. 10-1212982 and Korean Patent No. 10-2020584, moisture inside the ignition device cannot be completely removed, and there are limitations in preventing moisture from penetrating. If moisture exists inside the ignition device, the heating wire, which originally has low thermal energy, cannot emit enough heat energy to combust the ignition agent, and the ignition agent may be deteriorated or deformed by moisture. Accordingly, the combustion operation inside the fire extinguisher becomes uncertain, and malfunction of the fire extinguisher may become a problem. In other words, in an emergency situation such as a fire, extreme damage may occur as the fire extinguisher does not work properly.

Accordingly, regardless of the operating method of the ignition device, even if the heat energy generated from the heating board of the ignition device is small, it can provide sufficient heat energy to combust the fire extinguishing agent normally, and can effectively demonstrate its properties without being influenced by the environment. The need for a catalyst still exists.

Patent Document 1: Korean Patent No. 10-1212982 (December 11, 2012) Patent Document 2: Korean Patent No. 10-2020584 (2019.09.04.)

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings in order to provide a detailed description so that those skilled in the art can easily implement the technical idea of the present invention. In the following description, many specific details, such as specific components, are shown, which are provided to facilitate a more general understanding of the present invention, but it is known to those skilled in the art that the present invention can be practiced without these specific details. It will be self-evident to those who have it. Additionally, in describing the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted.

First, the general configuration and operating principle of a solid aerosol fire extinguisher will be described. In general, solid aerosol automatic fire extinguishing devices can be divided into an ignition section, a combustion section (or ignition section), a fire extinguishing agent section, and a discharge section. The ignition unit detects fire from the outside and induces electrical, chemical, or mechanical ignition within the aerosol fire extinguishing device. When the ignition material begins to burn due to this induction, the fire extinguishing agent is extinguished, producing fire extinguishing gas that is harmless to the human body. It is discharged through the discharge part. Fires can be extinguished by blocking oxygen or blocking the chain reaction of fire as extinguishing gases are released.

In embodiments of the present invention, an initiator for an ignition device that can be applied to a solid aerosol fire extinguisher having the above configuration and an ignition device including the same are provided.

One embodiment of the present invention relates to an initiator for an ignition device of a solid aerosol fire extinguisher comprising industrial nitride cotton.

Industrial nitrided cotton is a nitrate ester of cellulose, and its use has expanded from uses such as collodion, photographic film base, and nitrided screen lacquer to paints based on the fact that its viscosity drops when heated with water. Its current main use is as a lacquer, but it is also used for special printing inks. Nitrided cotton lacquer is applied to metal, leather, paper, wood, and various other applications. The coating film formed from it adheres tightly to these objects, is non-absorbent, provides beautiful gloss and excellent tactile feel, and has high strength. Since it is not easily damaged, it has its own unique application fields for various protection and decoration purposes along with its quick-drying properties.

In one embodiment of the present invention, industrial nitride cotton, which is commonly used as a coating film forming element of lacquer, is processed to have specific physical properties and applied as a catalyst for an ignition device of a solid aerosol fire extinguisher.

There are many types of combustible materials that can be used as a detonator for the ignition device of a solid aerosol fire extinguisher, but in reality, it is not easy to obtain a combustible material that can efficiently exhibit the necessary characteristics of a detonator with only a small amount of heat energy without environmental influence. To solve this problem, in one embodiment of the present invention, industrial nitride cotton, which is widely used and easily available as lacquer, etc., can be made to have specific characteristics and used as a catalyst for the ignition device of a solid aerosol fire extinguisher. Therefore, according to one embodiment of the present invention, by using an initiator for the ignition device of a solid aerosol fire extinguisher containing industrial nitride cotton, it helps in stable combustion of the ignition agent, and even when the heat energy generated from the heat ray is small, it is environmentally friendly. By effectively amplifying this without being affected by it, the performance of the fire extinguisher can be improved by effectively burning the fire extinguishing agent. In addition, the initiator for the ignition device of the solid aerosol fire extinguisher according to an embodiment of the present invention uses industrial nitride cotton that is easily available and easy to use, handle, and store, thereby increasing efficiency in manufacturing and use.

Industrial nitride cotton, which can be used as a catalyst for the ignition device of a solid aerosol fire extinguisher according to this embodiment, is a white material with a specific gravity of about 1.6 and has an ignition point of 180°C or higher. In addition, industrial nitrided cotton is resistant to weak acids, but hydrolyzes in strong acids and saponifies and decomposes in weak alkalis. It is completely soluble in ketones and esters, and has excellent compatibility with resins and plasticizers.

The industrial nitrided cotton that can be used as a catalyst for the ignition device of the solid aerosol fire extinguisher according to this embodiment may have a nitrogen content of 11.5 to 12.2% by weight.

If the nitrogen content exceeds the above range, it is a hazardous material with explosive and strong combustibility, and cannot be used, stored, transported, or handled as industrial nitride screen. In addition, if the nitrogen content is less than the above range, it may not function as an initiator for the ignition device of a solid aerosol fire extinguisher, or the performance may be insufficient. That is, if the nitrogen content is less than the above range, it cannot help in stable combustion of the ignition agent and cannot amplify the thermal energy of the heating element that operates with instantaneous power, making it difficult to apply as a detonator.

The industrial nitrided cotton that can be used as a catalyst for the ignition device of the solid aerosol fire extinguisher according to this embodiment may have a moisture content of 4.0% by weight or less.

If the moisture content exceeds the above range, the quality of the industrial nitrided cotton itself deteriorates, and therefore, it cannot exhibit sufficient properties as a catalyst for the ignition device of a solid aerosol fire extinguisher.

The industrial nitrided cotton that can be used as a catalyst for the ignition device of the solid aerosol fire extinguisher according to this embodiment may have an acid content of 0.05% by weight or less, preferably 0.03% by weight or less.

The lower the acid content of industrial nitrided cotton, the better it is in terms of physical properties. If the acid content is high, the solution of industrial nitrided cotton may become sulfurized during manufacturing, and the physical properties may deteriorate. As a result, the initiator for the ignition device of a solid aerosol fire extinguisher cannot demonstrate sufficient characteristics.

In this embodiment, the industrial nitrided cotton used as a catalyst for the ignition device of a solid aerosol fire extinguisher can be used in a state that has been processed to remove the wetting agent.

Industrial nitrided cotton is dangerous with respect to friction, impact, sparks, etc. and has poor storage stability, so it is sold and distributed in a wet state by adding wetting agents such as isopropyl alcohol, butyl alcohol, and water. In this embodiment, the wet industrial nitrided cotton is dried and processed to remove the wetting agent, so that combustion can be achieved even with a small amount of heat energy.

In this way, the drying and processing performed on industrial nitrided cotton primarily removes the wetting agent to ensure good combustion even with a small amount of heat energy, and secondarily, the industrial nitrided cotton becomes efficient as an initiator for the ignition device of a solid aerosol fire extinguisher. It can be made to have specific physical properties in order to function. As long as the above purpose can be achieved, detailed method steps, process conditions, etc. in drying and processing can be applied without particular restrictions.

In one embodiment, by treating industrial nitride screen by appropriately controlling the temperature and time, the wetting agent can be effectively removed and the material can have physical properties effective as an initiator.

For this purpose, at a temperature in the range of 30 to 170°C, preferably 40 to 150°C, more preferably 50 to 130°C, industrial use is carried out for 30 minutes to 10 hours, preferably 1 hour to 8 hours, more preferably 2 to 7 hours. Nitrid screen can be processed. The treatment temperature and time can be selected to remove the wetting agent of the industrial nitrided cotton and to exhibit sufficient properties as an initiator.

Alternatively, in another embodiment, the wetting agent may be removed through natural drying at room temperature (for example, 20 ± 5°C) for a sufficient period of time without separate heating.

In this way, by treating industrial nitride screen sold in a form containing a wetting agent under temperature and time control or naturally drying it at room temperature, the wetting agent can be effectively removed and its properties as a catalyst can be fully exhibited.

The initiator for the ignition device of a solid aerosol fire extinguisher according to an embodiment of the present invention can be applied regardless of the type of ignition device to improve the characteristics of the fire extinguisher. For example, when applied to an electric ignition device that obtains heat energy by operating a heater heating wire with sufficient power, the fire extinguishing agent can be burned effectively by helping to ensure stable combustion of the ignition agent. In addition, when applied to a self-generating ignition device that uses the instantaneous power generated from a self-generating device, it overcomes the limitation of power amount and effectively amplifies the thermal energy of the heating wire, thereby effectively burning the ignition agent and generating the resulting energy. The fire extinguishing agent can be burned normally by heat energy.

In other words, the initiator for the ignition device of the solid aerosol fire extinguisher according to an embodiment of the present invention helps in stable combustion of the ignition agent, and even if the heat energy generated from the heating board of the ignition device is small, it sufficiently amplifies it to ignite the fire extinguishing agent. It can provide sufficient heat energy for normal combustion, optimizing the operating performance of the fire extinguisher. In addition, the initiator for the ignition device of a solid aerosol fire extinguisher according to an embodiment of the present invention can effectively demonstrate the characteristics of an initiator without being influenced by the environment, and can be widely used in the ignition device of a solid aerosol fire extinguisher regardless of the operating method of the ignition device. It can be applied. Furthermore, the initiator for the ignition device of the solid aerosol fire extinguisher according to an embodiment of the present invention can be easily purchased and has the advantage of being easy to handle, which can further increase efficiency in terms of production and use.

Next, an ignition device for a solid aerosol fire extinguisher according to an embodiment of the present invention will be described.

Figure 1 is a schematic cross-sectional view of an ignition device for a solid aerosol fire extinguisher according to an embodiment of the present invention.

As shown in Figure 1, the ignition device 100 of a solid aerosol fire extinguisher according to an embodiment of the present invention includes a heating board 30 stored inside the body 10; Initiator (40) for the ignition device of a solid aerosol fire extinguisher; ignition agent (20); and a cap 50. In this embodiment, the initiator 40 for the ignition device of the solid aerosol fire extinguisher is according to the above-described embodiment and has been described in detail above, so the detailed description is omitted in this embodiment to avoid repetition.

The body 10 includes a heating board 30; Initiator (40) for the ignition device of a solid aerosol fire extinguisher; ignition agent (20); and may serve as a container for storing the cap 50 therein, and may be provided with at least one inlet 11.

In one embodiment, the body 10 may be made of a vacuum pack with a vacuum inside. Constructing a vacuum state can be done by various known methods. For example, the inside of the vacuum pack is filled with the initiator 40 and the ignition agent 20 through the inlet 11 of the vacuum pack 10, and then the inside of the vacuum pack is maintained in a vacuum state, so that the inside of the ignition device can remove moisture. Alternatively, for example, after filling the vacuum pack with the detonator 40 and the ignition agent 20, the air inside the vacuum pack can be sucked to create a vacuum state, or nitrogen can be charged using a vacuum pump, etc. This can create a vacuum state.

The cap 50 of the ignition device 100 of the solid aerosol fire extinguisher according to an embodiment of the present invention surrounds the heating board 30 and the detonator 40 for the ignition device of the solid aerosol fire extinguisher, and the upper and lower parts are open. It can have a shape. For example, the initiator 40 for the ignition device of the solid aerosol fire extinguisher may be disposed to surround the side, or the side and top, or the side, top and bottom of the heating board 30, and the ignition device of the solid aerosol fire extinguisher The cap 50 may be disposed to surround the outer surface of the container detonator 40. The upper part of the detonator 40 for the ignition device of the solid aerosol fire extinguisher without the cap 50 is open and can be in contact with the ignition agent 20, and the lower part is open and can be in contact with the body 10.

The cap 50 of the ignition device 100 of the solid aerosol fire extinguisher according to an embodiment of the present invention supports the initiator 40 for the ignition device of the solid aerosol fire extinguisher so that it does not escape from the heating board 30 and changes the surrounding temperature. Accordingly, the heat energy generated from the heating board 30 is prevented from being lowered, and it can serve to prevent combustion malfunction of the detonator 40 for the ignition device of the solid aerosol fire extinguisher.

In one embodiment, cap 50 may be made of thermoplastic resin.

For example, the cap 50 may include polyethylene (PE), polypropylene (PP), or a combination thereof.

The ignition agent 20 is placed in contact with the detonator 40 for the ignition device of the solid aerosol fire extinguisher stored inside the body 10 and surrounded by the cap 50, and is combusted by thermal energy, so that the fire extinguishing agent can be combusted. there is.

The ignition agent 20 may be combusted by heat and flame generated from the heating board 30 and/or by thermal energy amplified by the initiator 40. That is, the ignition device 100 of the solid aerosol fire extinguisher according to this embodiment uses an initiator 40 containing industrial nitride screen, thereby helping stable combustion of the ignition agent 20 and generating electricity from the heating board 30. Even in cases where combustion of the ignition agent 20 is difficult or insufficient using only the heat energy, the heat energy is effectively amplified by the initiator 40, so that the ignition agent 20 can be burned effectively. As a result, the fire extinguishing agent of the solid aerosol fire extinguisher can be burned normally and effective fire extinguishing performance can be achieved.

In one embodiment, the ignition agent 20 may further include an oxidizing agent to facilitate combustion. For example, oxidizing agents include potassium iodide, potassium bromide, lithium chloride, potassium iodate, potassium nitrate, potassium bromate, It may be selected from the group consisting of sodium nitrate, lithium perchlorate, AN/KN (ammonium nitrate phase-stabilized with potassium nitrate), and combinations thereof.

In one embodiment, the ignition agent 20 may further include a combustion accelerator. By further including a combustion accelerator, combustion of the ignition agent 20 can be achieved more easily, and as a result, normal combustion of the fire extinguishing agent can be improved.

In one embodiment, the combustion accelerator may include a metallic combustion accelerator, an organic combustion accelerator, or a combination thereof.

Examples of metallic combustion accelerators include, but are not limited to, titanium hydride, aluminum, aluminum hydride, copper, copper oxide, magnesium, magnesium hydride, titanium, titanium hydride, beryllium, and combinations thereof. Organic combustion accelerators include, but are not limited to, guanidine nitrate.

The heating board 30 can be installed on the opposite side of the inlet 11 inside the body 10 and can generate heat energy by receiving electricity generated from the fire detection device. Thermal energy generated by the heating board 30 may directly combust the ignition agent 20 or/or may be amplified by the initiator 40 to combust the ignition agent 20.

The heating board 30 may be surrounded by a detonator 40.

This heating board 30 may be made of a heating wire having a low heat energy source that uses instantaneous power. That is, the heating board 30 may be made of a heating wire with low thermal energy. For example, the heating wire may be a tungsten wire, a stainless wire, or a nickel alloy wire. Since the heat energy of this heating wire itself is small, the heat energy may not be sufficient to combust the ignition agent 20. Therefore, the ignition device 100 of the solid aerosol fire extinguisher of the present invention may further include an initiator 40 to amplify the heat energy generated from the heat wire.

Additionally, ignition jade (explosive material) may be applied to a heating element having a low heat energy source using the instantaneous power. A fire pit can provide heat in the form of a temporary explosion powered by an electric spark. Therefore, when using a heating wire coated with ignition jade, heat energy capable of burning the ignition agent can be generated without a detonator.

Additionally, the heating board 30 may be made of a heating wire having a high-thermal energy source that uses continuous power. That is, the heating board 30 may be made of a heating wire with high thermal energy. For example, the heating wire may be a nichrome or nickel alloy wire, or a heating wire with high specific resistance. Since these heat rays can emit sufficient heat energy, the ignition agent 20 can be burned immediately without an ignition or detonator.

The ignition device of the solid aerosol fire extinguisher according to this embodiment can easily combust even with a small amount of heat energy, can be easily purchased, and uses an initiator containing industrial nitride screen that is easy to handle, so that the ignition device's heating board is used. Even if the generated heat energy is small, it can be sufficiently amplified to provide enough heat energy to normally burn the fire extinguishing agent, thereby optimizing the operating performance of the fire extinguisher.

Next, with reference to FIGS. 2 and 3, a solid aerosol fire extinguisher to which an ignition device according to an embodiment of the present invention is applied will be described.

Figure 2 is a schematic cross-sectional view of a solid aerosol fire extinguisher according to an embodiment of the present invention, and Figure 3 is a cross-sectional view of a solid aerosol fire extinguisher according to an embodiment of the present invention. In the description of the solid aerosol fire extinguisher 1000, the initiator 40 for the ignition device of the solid aerosol fire extinguisher and the ignition device 100 of the solid aerosol fire extinguisher described in detail in the above-described embodiments are described in detail in order to avoid repetition. The explanation is omitted.

The solid aerosol fire extinguisher 1000 of the present invention may include a fire extinguishing agent 200 that generates fire extinguishing gas through combustion and an ignition device 100 for burning the fire extinguishing agent. As shown in FIGS. 2 and 3, an ignition device 100 is disposed on one side of the fire extinguisher, and a fire extinguishing agent 200 can be stored around the ignition device 100. The fire extinguishing agent 200 is combusted by the ignition device 100, and the fire extinguishing component in the form of a solid aerosol can be discharged through the outlet 400 provided on the other side of the fire extinguisher. A coolant 300 may be provided between the fire extinguishing agent 200 and the outlet 400. The coolant 300 provides a space through which the fire extinguishing agent can pass, and can serve to cool the combustion heat generated when the fire extinguishing agent is burned through an endothermic reaction. Meanwhile, a breathable tape 500 may be optionally provided in the outlet 400. The breathable tape 500 can continuously discharge explosive gas inside the fire extinguisher to the outside.

Next, the operation of the solid aerosol fire extinguisher 1000 of the present invention will be described. When a fire breaks out in a space where a solid aerosol fire extinguisher is installed, electricity is instantly and automatically supplied by the fire detection device, generating heat and flame in the heating board 30 of the ignition device 100. At this time, the ignition agent 20 is burned directly by the heat energy generated, and/or this heat energy is amplified by the initiator 40, and the ignition agent 20 is burned by the amplified heat energy, thereby generating The flame burns the fire extinguishing agent 200 and generates a solid aerosol. The solid aerosol is cooled as it passes through the coolant 300 and is discharged out of the fire extinguisher through the outlet 400. The discharged solid aerosol extinguishes the fire by blocking oxygen in the area where the fire occurs or by blocking the chain reaction of the fire.

The present invention is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible without departing from the technical spirit of the present invention. It will be clear to those who have knowledge.
