Description
Technical field
The present invention relates to technical field of fire control, particularly relating to a kind of gas automatic fire extinguisher with reporting to the police.
Background technology
In the numerous disasters run in the development of the mankind, fire is the disaster with maximal destruction ability of generally acknowledging in entire society.The mankind can control fire and utilize, and are important symbols of development of civilization.Nowadays, be no matter the skyscraper of plain edition (such as residential houses) or luxury (such as luxurious hotel), the popularization and application of equal pay attention to day by day fire prevention and safe practice.Analyze from present stage, the present canot compare with the past for the utilization rate of the fire in people's daily life, combustion gas, electricity, also brings the high rate of fire and blast in use.Fire is once occur, and the consequence of appearance is unpredicted.Usually due to the not predictability of fire generation and the retardance of fire extinguishing and warning, cause the loss that human and material resources cannot be retrieved.
Because fire breaks out the huge injury brought, the attention rate of people in fire fire extinguishing and warning is improved constantly, and the building lacking fire-distinguishing alarming system also start to install all kinds of extinguishing device and warning system one after another.
In recent years, increasing construction project owner initiatively proposes to adopt gas extinguishing system to protect important or valuable equipment, region.For putting out the charging equipments such as fuel gas, underground hydraulic lubricating oil station, changed into switchhouse equipment, generating set, computer room, valuable, precision equipment and electric wiring etc. are not suitable for the fire put out with water, and extinction using gas is effectively the cleanest fire extinguishing means.
Several gas extinguishing systems conventional at present mainly contain CO
2gas extinguishing system, heptafluoro-propane (FM-200) fire extinguishing system, inert gas (IG-541) fire extinguishing system and condensed aerosol fire extinguishing device etc.
CO
2gas extinguishing system: under normal temperature condition, CO
2exist with colourless, tasteless gas, according to its physical characteristic, have two kinds of storage modes: storage of higher pressures (under 20 DEG C of temperature, pressure store is 5.17Mpa) and low pressure store (under-18 DEG C of temperature, pressure store is 2.07Mpa), CO
2extinguishing mechanism mainly suffocates, and being secondly cooling, is physical reactions.In the alternative system of numerous haloalkane extinguishing systems, CO
2fire extinguishing system is the most ripe, and application is also the most extensive, and high-voltage applications is comparatively general at home, and in recent years, the development of low-pressure system application technology was also very fast.CO

Cigarette Lip river is (IG-541) fire extinguishing system to the greatest extent: cigarette Lip river is full of a kind of inert gas agent that nitrogen, argon gas and carbon dioxide mix with the volume ratio of 52:40:8.Its density is similar to the density of air.Its extinguishing mechanism is the oxygen concentration by reducing in guard plot, makes it can not maintain burning and reaches the object of fire extinguishing, being physical reactions, belonging to fireproofing passiveness.It is a kind of environmental type extinguishing chemical; chemical reaction is there is not when putting out a fire; nontoxic, corrosion-free, there is good insulating performance, can not form harm to proterctive equipment, and extinguishing chemical is inexpensively; fed distance is also very long; but owing to being fireproofing passiveness, extinguishing effect is slightly poor, the mode that its high-pressure gaseous stores brings the increase of design gas cylinder quantity; floor space is large, the shortcoming that system cost is high.
Hot aerosol fire extinguishing system: usually said aerosol, refers to air to be decentralized medium, the colloidal dispersion being dispersate with solid-state or liquid particulate.Aerosol extinguishing agent is made up of oxidant, reducing agent, burning velocity controlling agent and binder.Hot aerosol is again K type aerosol and S type aerosol.K type vapour colloidal sol extinguishing mechanism is absorbing and cooling temperature, Chemical Inhibition, suffocate and air-isolation, mainly based on Chemical Inhibition.S type vapour colloidal sol is consistent with K type extinguishing mechanism, has just changed strontium salt into by sylvite.Aerosol fire-extinguishing efficiency is higher on the whole, and cost is very low, arrange flexibly, but the most fatal defect causes secondary injury to precision instrument and equipment, historical relic, archives.
Often kind of gas physical property, chemical property, fire extinguishing mechanism different; so should for different item types, different project places, different object of protections; choose reasonable gas is put out a fire; protect the safety of personnel and property to greatest extent; and the advantage of extinguishing chemical can be played to greatest extent; maximize favourable factors and minimize unfavourable ones, finally determine scheme of the most reasonably putting out a fire.
