Fire-fighting gas fire-extinguishing system is a fire-extinguishing system in which the fire-extinguishing agent is stored in a gas or gas state in a pressure vessel, and the state of the gas (including steam and aerosol) is used as the fire-extinguishing medium. Fire-fighting gas fire-extinguishing systems are divided into many types according to the type of fire-extinguishing agent. What are the common fire-gas fire-extinguishing systems?
1. Heptafluoropropane gas fire extinguishing system
Heptafluoropropane (HFC-227ea) gas fire extinguishing system is a high-efficiency fire extinguishing equipment. Heptafluoropropane fire extinguishing agent is a clean, colorless, odorless, low-toxicity, good insulation, and no secondary pollution clean gas. The ozone layer has zero depletion potential (ODP), which is the most ideal replacement for the halogenated 1211 and 1301 gas fire extinguishing systems.
Heptafluoropropane does not contain solid dust and oil stains. It is released in a gaseous state in liquid storage. It can be discharged naturally after spraying or quickly discharged by the ventilation system. There is no residue on the site and no secondary damage to the protected object.
The spray time of the sevoflurane gas fire extinguishing system is very short, which greatly reduces the damage of the equipment during the fire and reduces the loss for the owner. Fire-fighting operation is simple and reliable: there are three starting modes: automatic, electrical manual and mechanical, which ensure that fire can be extinguished under any circumstances.
Heptafluoropropane gas fire extinguishing system is a fully submerged system. It can extinguish fires of A (surface fire), B, C and electrical equipment. It can be used to protect places where people are often. It is especially suitable for protecting high-precision electronic equipment and valuables. It is widely used. Fire protection in key protective areas such as computer rooms, power distribution rooms, archives rooms, valuable industrial equipment, libraries, clean rooms, etc., can be used in protective areas where people are often working.
Second, high-pressure carbon dioxide gas fire extinguishing system
The high-pressure carbon dioxide gas fire extinguishing system is 100% carbon dioxide gas. The carbon dioxide fire extinguishing agent has a wide range of sources, low price, high electrical insulation, clean and no residue, long-term storage without deterioration, and will not damage the equipment. It will not pollute the fire environment during fire extinguishing. It quickly dissipated without leaving any traces.
Carbon dioxide is a moderately toxic substance. When the concentration of carbon dioxide in the air reaches 2%, it will cause people to feel unpleasant. When the concentration reaches 7% to 9%, it will cause difficulty in breathing, vomiting, numbness and confusion. When the concentration reaches 10%, a person stays in this environment for one minute and loses consciousness. Its local concentration greatly exceeds this concentration. There is a certain danger. There have been too many domestic poisoning incidents due to the leakage of carbon dioxide into the protective area. At present, relevant national regulations have listed the high-pressure carbon dioxide gas fire extinguishing system as protection that is not suitable for people who work frequently. Area.
High-pressure carbon dioxide gas fire extinguishing systems are widely used in fire protection in key protection areas prone to fire, such as power plants, power stations, rolling mills, printing presses, immersion oil tanks, spray booths, and pharmaceuticals.
Third, the fire detection pipe gas fire extinguishing system
The fire detection tube gas fire extinguishing system is a simple, low cost and highly reliable independent automatic fire detection gas fire extinguishing system. The fire detection tube gas fire extinguishing system uses flexible and bendable fire detection tubes as the fire detection and alarm component. At the same time, this fire detection tube can also serve as the transportation and discharge pipe of the fire extinguishing agent. The flexible fire detection tube can be conveniently arranged to Near each potential ignition point, the alarm is combined with fire extinguishing, and the detection response time is fast. Once a fire occurs, in the early stage of the fire, the fire detection pipe near the ignition point is heated and ruptured, and the fire extinguishing agent is immediately released to extinguish the fire.
The fire detection tube gas fire extinguishing system does not require any power supply, does not require special smoke and temperature detectors, does not require complex equipment and pipelines, and uses its own storage pressure to detect, extinguish, and extinguish fire sources quickly, accurately, and effectively.
The fire detection pipe gas fire extinguishing system can greatly reduce the cost of the project, and also reduce the cost of each fire extinguishment, and will not cause any harm to personnel. The use of fire detection and fire extinguishing devices can change the protection of rooms with larger closed spaces to directly protect valuable equipment of various smaller closed spaces, which makes up for the shortcomings of existing fire protection products that cannot extinguish such flames.
Fourth, IG541 mixed gas fire extinguishing system
The fire extinguishing agent of IG541 mixed gas fire extinguishing system is a gas composed of nitrogen, argon and carbon dioxide gas in a certain ratio. These gases are naturally present in the atmosphere, and there is no loss of the atmospheric ozone layer, and it will not affect the earth. The "greenhouse effect" has an impact, and the mixed gas is non-toxic, colorless, odorless, non-corrosive, non-conductive, does not support combustion, and does not react with most substances. It is an ideal environmentally friendly fire extinguishing agent.
IG541 mixed gas fire extinguishing system is mainly suitable for places with frequent people and work such as electronic computer room, communication room, power distribution room, oil-immersed transformer, self-provided generator room, library, archives room, museum and bills, cultural relics database.
V. Hot aerosol fire extinguishing system
The hot aerosol fire extinguishing system is a new type of fire extinguishing agent. The fire extinguishing agent is a solid mixture composed of an oxidant, a reducing agent, a burning rate control agent and a binder.
The hot aerosol fire extinguishing system is stored in a solid state at normal temperature and pressure without leakage problems and easy to maintain. It belongs to a pipeless fire extinguishing system, which is flexible to install, does not need to arrange pipes, and has a relatively low engineering cost. ,
The hot aerosol fire extinguishing system can be divided into K type and S type according to the type of extinguishing agent. According to the temperature of the nozzle of the fire extinguishing device, it can be divided into temperature-limiting type and non-temperature-limiting type. Used to extinguish electrical appliance fires, solid surface fires, and liquid fires.
According to the descriptions of the above types of fire gas fire extinguishing systems, which fire gas fire extinguishing system to choose needs to be designed and installed according to the site of the protective area, a professional engineer needs to design a corresponding solution according to the specifications and site conditions.
