READ MOREWorking Principle of Dry Powder Chemical Extinguisher
Around the world, the frequent occurrence of fire accidents poses a severe challenge to people's life safety and property protection. In order to effectively deal with fire risks, dry powder chemical fire extinguishers, as an important fire-fighting equipment, have gradually become the preferred fire-fighting tool for various places with their excellent fire-fighting efficiency and wide applicability. Ningbo Kaituo Valve Co., Ltd. focuses on the research and development and production of fire-fighting equipment, and is committed to providing high-quality dry powder fire extinguishers to meet the diverse needs of the market.
Basic composition of dry powder chemical fire extinguishers
The core component of dry powder chemical fire extinguishers is dry powder fire extinguishing agent, which is usually composed of a variety of chemical substances, including ammonium phosphate, ammonium sulfate and sodium chloride. These chemical components not only have excellent fire-fighting effects, but also have corresponding inhibitory effects on different types of fires. The basic structure of dry powder fire extinguishers includes the following key parts:
Gas drive system: This system usually uses compressed gas (such as nitrogen) as the drive source, which can effectively drive the dry powder fire extinguishing agent to spray to the fire source.
Nozzle: The nozzle is designed to spray the dry powder fire extinguishing agent evenly onto the flame, ensuring that the fire extinguishing agent can fully cover the burning material and enhance the fire extinguishing effect.
Storage tank: The storage tank is used to safely store the dry powder fire extinguishing agent and the gas drive system to ensure that it can be quickly released when needed to provide timely fire extinguishing response.
Working principle of dry powder chemical fire extinguisher
The fire extinguishing principle of dry powder chemical fire extinguisher mainly achieves its fire extinguishing effect through physical and chemical effects. The specific mechanism is as follows:
Spraying mechanism: During operation, the user pulls the safety bolt of the fire extinguisher and presses the nozzle, and the compressed gas is quickly released, pushing the dry powder fire extinguishing agent out of the storage tank. The sprayed dry powder forms a covering layer, which quickly covers the surface of the flame and the burning material, forming an effective fire extinguishing barrier.
Suffocation effect: After the dry powder fire extinguishing agent is sprayed, it will quickly cover the surface of the burning material to form a protective film. This film can effectively isolate oxygen and inhibit the burning of the flame. The combustion reaction depends on the supply of oxygen. When the oxygen is isolated, the flame will gradually weaken and eventually go out.
Chemical reaction inhibition: The chemical components in dry powder fire extinguishing agents can react with free radicals in the flame, effectively inhibiting the combustion reaction. Specifically, some components in the dry powder can capture free radicals in the flame, thereby interrupting the combustion chain reaction, reducing the flame temperature, and further accelerating the fire extinguishing process.
Cooling effect: Although the main function of dry powder fire extinguishers is not cooling, the spread of dry powder during the fire extinguishing process will also take away some heat, thereby helping to reduce the temperature of the fire source. For high-temperature flames, reducing their temperature is an important part of extinguishing the flame.
Scope of application of Dry Powder Chemical Extinguisher
In the field of fire safety, dry powder chemical fire extinguishers have become an indispensable and important fire-fighting equipment in various places due to their excellent fire-fighting performance and wide applicability.
Basic characteristics of dry powder chemical fire extinguishers
The fire extinguishing agent used in dry powder chemical fire extinguishers is mainly composed of chemical components such as ammonium phosphate, ammonium sulfate, and sodium chloride, which can effectively extinguish various types of fires. Its notable features include:
Versatility: Dry powder fire extinguishers can effectively deal with Class A (solid), Class B (liquid) and Class C (gas) fires, and have a very wide range of applications, covering a variety of scenarios from home to industry.
High efficiency: After spraying, dry powder fire extinguishing agents can quickly cover the burning materials, forming a protective film that isolates oxygen, thereby quickly suppressing the spread of flames and ensuring that the fire is controlled in time.
Easy to operate: The use of dry powder fire extinguishers is relatively simple, and anyone can quickly master their use in an emergency, reducing the risk of fire extinguishing failure caused by improper operation.
Scope of application of dry powder chemical fire extinguishers
Industrial field
In industrial production, dry powder chemical fire extinguishers are widely used in chemical, petroleum, manufacturing and other industries. These industries usually have flammable and explosive substances, and the versatility of dry powder fire extinguishers provides them with a powerful means of fire prevention and control. For example:
Chemical plants: Chemical plants often store a large amount of flammable chemicals. Dry powder fire extinguishers can effectively deal with fires caused by chemical reactions and ensure production safety.
Oil refining: During the oil refining process, the presence of flammable liquids and gases makes the risk of fire extremely high. Dry powder fire extinguishers can quickly extinguish flames caused by leaks and avoid serious losses.
Commercial places
Dry powder fire extinguishers also play an important role in commercial environments. Supermarkets, shopping malls, restaurants and other places often involve electrical equipment and flammable items, and the risk of fire cannot be ignored. The applicability of dry powder fire extinguishers makes them an ideal choice for these places:
Supermarkets and shopping malls: Due to the wide variety of goods, dry powder fire extinguishers can effectively deal with fires caused by electrical failures or flammables, providing safety for customers and merchants.
Catering industry: The accumulation of oil smoke and grease in the kitchen increases the risk of fire. Dry powder fire extinguishers can quickly extinguish flames caused by grease to ensure catering safety.
Home environment
Dry powder fire extinguishers are also indispensable for use in the home. Electrical appliances, kitchen utensils, and outdoor barbecues in the home all pose fire risks. In order to protect the safety of family members, dry powder fire extinguishers have become an effective tool for home fire prevention:
Kitchen fire: When frying food, excessive oil temperature may cause a fire. Dry powder fire extinguishers can quickly extinguish the flames in the kitchen, avoid greater losses, and ensure family safety.
Electrical appliance fire: Electrical appliances used in the home, such as refrigerators and microwave ovens, have the risk of short circuits causing fires. Dry powder fire extinguishers can effectively deal with such fires and reduce the possibility of accidents.
Transportation
In the field of transportation, especially on ships and aircraft, dry powder fire extinguishers are also essential firefighting equipment. Due to the special environment of ships and aircraft, the occurrence of fires may lead to serious consequences, so efficient fire-fighting equipment is needed:
Ship: The operating environment at sea is complex. Dry powder fire extinguishers can quickly respond to fires in ships, protect the safety of crew members and cargo, and ensure the smooth sailing.
Aircraft: The electronic equipment and fuel in the aircraft make the fire risk higher. The rapid response ability of dry powder fire extinguishers can effectively control the fire and ensure the safety of crew members and passengers.
