Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire extinguisher,

The present invention relates to an extinguishing agent for fire fighting in an urban area, and more particularly, to a fire extinguishing agent that moves when a fire occurs in a city fire, . The present invention relates to an extinguishing agent for fire fighting in a city fire which can be carried easily and lightly. It is an environmentally friendly material and has no secondary environmental pollution problem. It is safe to use even if exposed to human body.

A fire is a person's unintentional or deliberate fire, which can be triggered by the use of a fire extinguisher or is a chemical explosion.

       The types of fire are as follows.

1. Building, structure fire - When a building, structure, or object inside it is burnt

2. Cars and railway cars - When cars, railways, towed vehicles, or objects in it

3. Fire of dangerous goods, gas manufactory, etc. - Fire at the place where dangerous goods or gas is manufactured, stored and handled

4. Forest fire - firewood or forest fire, or fire in a house without building

5. Other fire - Any fire that does not fall on top of it (garbage incineration, bonfire, etc.)

       Table 1 below shows the classification of fire by A, B, C, D classifications.

Classification of fire Classification color Causative substance How to extinguish Remarks General Fire (Class A) White Wood, cotton, paper, rubber, etc.
Fire due to general combustible materials. It can be digested with water. After birth, the ashes remain. Oil gas fire (Class B) yellow Fire caused by gas such as oil, bunker C, tar, paint, gas, LNG, LPG, city gas.
It is caused by gas leakage and combustion and explosion, and gas may cause explosion. Cooling extinguishment of liquid-cooling action involving water,
Using the air shut off.
Vast digestion (oil)
(Gas), water has no effect and can only be used as a soil or fire extinguisher. If it mixes with air at a certain rate, it does not remain ashes by fire. Electric fire (Class C) blue Electric spark, short circuit, overload, etc., cause electric energy to be transferred to fire. Choking digestion. Use special fire extinguisher. There is a risk of electric shock if water is used. Metal Fire (Class D) Gray, silver It may be accompanied by explosion of metal powder due to fire by metal materials such as iron, magnesium, potassium, sodium and zirconium. It is used for the smothering and covering effect of dry sand. Alkylaluminum is extinguished by explosive vermiculite or expanded perlite and special fire extinguisher. There is a risk of explosion if water is used.

Fire extinguishers are one of the instruments used to extinguish fire. It is mainly used for emergencies such as a fire, and is filled with chemicals that can easily turn off the fire when it is sprayed. It can be used by hand and is easy to operate and is used in the early stages of fire.

       In 1816, British soldier George Major, who invented equipment similar to the first modern fire extinguisher, was in a 3 gallon copper container containing pearlite (potassium carbonate) and compressed air.

       Depending on the kind of digestive medicine, it is classified as water extinguisher, foam, fire extinguisher, liquid fire extinguisher, powder fire extinguisher.

       We reach fire extinguisher which uses water as fire extinguishing medicine. There are various kinds of fire extinguishers that mainly extinguish by cooling effect and some act as choking. It is mainly used for evolving general fire (Class A, general fire) and not for oil (Class B) and electric (Class C) fire.

       It is a fire extinguisher that uses carbon dioxide as compressed digestion liquor. It mainly extinguishes by the action of the asphyxiation, and the liquefied carbon dioxide also evaporates and cools. It can be used for most fires, and there are few remnants of fire extinguishing medicines, and there is little damage to fire extinguishers, so they are often found in museums and museums. However, due to the risk of suffocation, underground and general households are prohibited from using and using the beach.

       It is a fire extinguisher that uses powdered digestive medicine. It contains micropowder made of various chemicals and is ejected by using pressurized gas. Generally the most common is ABC powder fire extinguisher, which is a major component of ammonium phos- phate. It is extinguished mainly by cooling and asphyxiation and inhibition. It is most widely used because it is available for most fires and is inexpensive. Since the powder remains after spinning, the digestion object may be damaged.

       It is a fire extinguisher that uses liquid chemical chemicals. The body is turned upside down and shaken, and aluminum sulfate solution and carbon dioxide are mixed together and sprayed in the form of foam, so that the fire is suppressed by the action of choking. It is mainly used for general fire (Class A) and oil fire (Class B) evolution. Although the digestion performance is very good, it has a disadvantage that it is cumbersome to use and has a high possibility of corrosion due to medicinal materials, so it is not produced at present.

       It is a fire extinguisher that uses halogen compound gas as medicine. Halon 1301 (brominated trifluoromethane), Halon 1211, Halon 2402 and other gases are mainly used for digestion by the action of choking. It can be used for most fires (A to D class), and there is no residue of fire extinguishing medicines and less damage to fire extinguishers. It is very effective in digestion, but it is expensive, it is toxic to halon gas and can be harmful to the human body. Because it contains substances that destroy the ozone layer, production and sales are prohibited in recent years.

In other words, existing urban fire evacuation methods have low efficiency, low safety, and can cause secondary environmental damage.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The mixed composition that can be used in the fire extinguisher for fighting fire of the city according to the present invention is roughly divided into main component and auxiliary component. The main component is used as a main site for the fire escape of the city, and at the same time it prevents the combustion. The auxiliary component functions as a carrier to support the main constituent gas component while helping the main component fire evolve.

       The main components of the mixed composition that can be used in a fire extinguisher for fire fighting according to the present invention are carbon dioxide, argon and helium, and the auxiliary components are tonalite, granitic rock, and gibbsite.

       The composition ratios of the mixed compositions that can be used in a fire extinguisher for fire suppression of municipal fire according to the present invention are described in Table 1 below.

       The concrete composition of the mixed composition usable in the fire extinguisher for fire fighting by municipal fire according to the present invention is as follows.

       Carbon dioxide (CO2) is a gas produced when a carbon or a compound is completely burned, or when a creature breathes or ferments (fermentation), and occupies about 0.035% of the atmosphere. Carbon dioxide is easily liquefied when it is pressurized with a colorless, odorless gas. If you compress it further, you can make solid dry ice. If dry ice is placed at normal temperature and normal pressure, it will sublimate and fly to gas. Carbon dioxide is slightly soluble in water and becomes carbonic acid, creating a weak acid solution. The solubility of gas increases with increasing pressure and lower temperature, so when making carbonated beverages, it dissolves carbon dioxide with low temperature and high pressure. The reason I feel sick when I drink a carbonated drink is because the carbon dioxide dissolved in the form of carbonic acid in the water stimulates the mouth to evaporate and evaporate due to the low pressure and high temperature environment. Since carbon dioxide reacts with calcium hydroxide to form calcium carbonate, which is a white precipitate, when carbon dioxide is passed through the limestone, which is a solution of calcium hydroxide dissolved in water, the solution becomes cloudy. So we use a lot of lime water to detect carbon dioxide. Carbon dioxide is obtained industrially by adding acid to limestone or heating limestone. Carbon compounds such as alcohols can be produced with water when burned, or even in the process of organisms decomposing organic matter. Life forms the energy needed for life by decomposing organic matter through respiration. At this time, carbon dioxide is produced and exhaled into the air through exhalation. Because carbon dioxide interferes with combustion as opposed to oxygen, a fire extinguisher that uses carbon dioxide can be used to turn off the fire.

       Argon is a gas belonging to the period 3 group 18 in the Periodic Table of the Elements, and has an elemental symbol Ar, a melting point of -189.35, a boiling point of -185.85, and a density of 1.784 g / L. It is a mono-molecular gas with little reactivity. It is also called an inert gas. It exists in the air at the rate of 0.94%, and is the most abundant among inert gases. Argon is a colorless, tasteless, odorless inert gas that accounts for 0.94% of the atmosphere and is rich in air, followed by nitrogen and oxygen. Heavier than air and soluble in water and organic solvents. It is known that the outermost electrons are completely filled (3s2 3p6), but they do not bond with other elements. However, they form a class rate trapped in the shape of a basket in the molecule of ice crystals or other substances such as hydroquinone, an organic compound. A large amount of argon is obtained by fractional distillation, which is a method in which the air is cooled and liquefied and then the temperature is gradually increased. Because argon is contained in natural gas, refining natural gas can yield argon as a byproduct. Argon is often used to protect materials from other gases such as oxygen. It is used as an internal filling material for a bulb fluorescent tube or the like by using stable and inactive properties at high temperature. It is also widely used in the manufacture of steel, welding, manufacturing of semiconductors, and smelting of metals. Argon is also used to measure the age of rock formation (potassium-argon dating) using isotope decay. When discharged at high temperature or low temperature, it emits an unusual color and is used in lighting equipment.

       Helium is an inert gas belonging to the period 1 18 group on the Periodic Table of the Elements, and is the next most abundant element in the universe. The element symbol is He, the melting point is -272.20C (2.5MPa), the boiling point is -268.93C, and the density is 0.1786g / L. It is a mononuclear gas with little reactivity. It is also called an inert gas. It has no color and smell and there is a very small amount in the air. Elements of group 18 are mononuclear molecules and their chemical properties are very inert and do not react with most other elements, so they are called inert gases. Helium is the next gas to hydrogen in gas at room temperature, has no color and odor, is the most reactive of all known elements and is near ideal gas. It has the lowest boiling point of chemical elements and is the only element that exists as a liquid in the absolute state due to its high zero point energy at normal pressure (note that isotopes of liquid helium can exist as solid at constant temperature and pressure). The Earth contains very small amounts of 0.0000524% in the atmosphere. In the universe, however, it is the next richest element of hydrogen, accounting for 24% of all elements in the galaxy. The sun is a massive gas mass consisting of three quarters of the hydrogen and one quarter of the helium. The nuclear fusion reaction occurs in the center of the nucleus, where hydrogen atoms bond to each other to form helium. Hydrogen and helium also account for the majority of the total. Since the nucleus of the radiation element is collapsed, it emerges when it changes to another element after releasing the alpha line. Therefore, it is contained in the radioactive minerals such as Clévén stone monazite. It is industrially most common to separate and produce in natural gas. It liquefies other coexisting gases at low temperature and high pressure, and then helium of constant purity is obtained. Economical resources are extremely limited and are called rare gases. Gaseous helium is safer than light, explosive hydrogen, so it is used in balloons and airships. It is used for leakage test for carrier gas welding of neon sign analyzer. Because of its low solubility in blood, it can prevent diarrhea and is used as a nitrogen substitute for deep-sea diver oxygen bottle. Helium is used in semiconductor fabrication and superconducting magnets when welding is not to leave trace of oxidation. Liquid helium is used as a coolant to achieve ultra-low temperature because it has a low boiling point of -269, which is close to absolute zero 0K (-273) under atmospheric pressure. It is being applied to advanced science and industry such as superconducting technology by taking advantage of the characteristic of cryogenic temperature.

       Tonalite is semicrystalline granite rock, which is highly colored with about 40% of high-iron minerals. The major component minerals are quartzite minerals (quartz (about 30%) and plagioclase, and the high-iron minerals are usually biotite and biotite. Sub-component minerals are chlorite, alternating plagioclase and sericite, and small amounts of opaque minerals. Inhomogeneous quench quartz filled the gap between the plagioclase and normal amphibole grains. Andodecane was the component of plagioclase measured by the angle of incidence of the twisted twin. Plagioclase is also observed. Usually hornblende is twinned, and one or both cleavages are observed, while the pleochroism in Nicole is brown to greenish brown.

       Granodiorite porphyry is a semi-acute myocardium with rounded and acuminate structures as a whole. The sedimentary rocks (maximum 1.5mm) are composed of limestone and semi-limestone plagioclase and quartzite, and the content of plagioclase is dominant. The stalagmites consisted of microcrystalline or amorphous crystals of 0.3 mm or less. The minerals identified are quartz, plagioclase, quartz, green to green brown hornblende (normal hornblende) and small amounts of biotite. Other opaque minerals, sericite, and zircon are observed. On the outskirts of the peninsula, there is a weak hanamarapakibi texture (corona or reaction kite). The component of plagioclase is oligoclase.

       Gibbsite is a monoclinic mineral with a hardness of 2.5, specific gravity of 2.3 ~ 2.4, gray, reddish red, gray green. It is an important ore of aluminum. The chemical composition is Al (OH) 3. It usually forms a lump or a globular form, and rarely forms a hexagonal plate of small crystals. A hardness of 2.5, and a specific gravity of 2.32.4. The cleavage is perfect on the 001 plane. It is a major mineral of bauxite. It is produced in clay containing a lot of aluminum such as late lite. Especially it is in the weathering zone of tropical or sub-tropical andesite such as Brazil, India, Australia and Brazil, and low temperature hydrothermal mineral is low, It is also calculated as a charged ore. Theoretically, it contains 38.5% aluminum and is an important ore of aluminum.
