Technical field
The utility model belongs to fire fighting extinguisher, particularly a kind of low pressure water and chemical gas extinguishing chemical thin water in combination
Mist fire extinguishing system.
Background technology
At present, in the places such as office space, market, factory building, warehouse, communications equipment room, usually used fine water mist fire-extinguishing system.
Fine mist fire-fighting has many superiority, due to water droplet diameter very little, the water of relatively same volume, and its surface area
Increase severely, so as to strengthen the efficiency of heat exchange, serve extraordinary cooling-down effect.Rapidly by vapour after water mists absorption heat
Change so that volume drastically expands, and generally reaches more than 1700 times, so as to reduce the oxygen concentration in air, it is suppressed that in burning
Oxidation reaction speed, serve the effect of asphyxia.The extinguishing mechanism of water mists as can be seen here：First, cooling efficiency, absorbs
Heat；Second, smothering action, blocking oxide reaction.In addition, water mists have the efficiency of very superior blocking radiant heat transfer,
Strong heat radiation can effectively be blocked.But fine mist fire-fighting its compared to for chemical gas extinguishing chemical, blow-off velocity is slow.
Heptafluoro-propane, fluoroform, perfluor hexanone, bromine fluoropropene etc. are as clean chemical gas extinguishing agent because it has
Efficiently, cleaning, it is environmentally friendly many advantages, such as and get most of the attention.Extinguishing chemical can suppress flame rapidly by physics and chemical mode
Propagate, the physical vapor stage absorbs substantial amounts of heat, and chemical reaction produces a large amount of free radicals and blocks burning chain reaction, quickly puts out
Fire extinguishing flame.Whole fire extinguishing procedure, fire extinguishing is rapid and is remained without solid, powder.But it can produce one kind in fire extinguishing procedure
Poisonous highly acid gas HF, can heavy corrosion hardware, electronic equipment in wet environment.
Therefore, if both are organically combined, you can realizing reduces smokescope, dissolves and absorbs toxic gas, quickly
Purify fire field environment.Especially suitable for places such as office space, market, factory building, warehouse, communications equipment rooms.Existing water mists are big
Mostly heavy pressure fine spray, the pipeline of its high-pressure system, nozzle, the operating pressure of accessory and water pump are required to very high, and cost is relative
Costliness, and nozzle easily occurs to block failure.Therefore, it is necessary to research and develop one kind can be by clean chemical gas and fine water mist fire-extinguishing system
With reference to, and can reduce to high-pressure system requirement, the fire extinguishing system being applied in important item storage closing space for avoiding blocking.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided by clean chemical gas and fine mist fire-fighting
System combines, and reduces the fire extinguishing system for high-pressure system requirement, avoiding blocking.
The utility model solves its technical problem and is achieved through the following technical solutions：
A kind of low pressure water and the united fine water mist fire-extinguishing system of chemical gas extinguishing chemical, it is characterised in that：Including purifying
Learn extinguishing agent storage unit, fire water pipeline, compressed air unit, proportioner and fine mist spray head unit, clean chemistry
Extinguishing agent storage unit and fire water pipeline are respectively connecting to the gas access of proportioner, liquid inlet and carry out ratio tune
Solution, the outlet of proportioner and compressed air unit are connected to fine mist spray head unit, and fine mist spray head unit includes air water
Internally piloted valve, calm the anger water premixed device and shower nozzle, the outlet of proportioner are connected to the feed tube of air water internally piloted valve, compressed air list
Member is connected to the air inlet pipe of air water internally piloted valve, and drain pipe, the escape pipe of air water internally piloted valve are connected to the feed liquor for water premixed device of calming the anger
Mouth and air inlet, the port of export for water premixed device of calming the anger connect the shower nozzle.
Moreover, it is described calm the anger water premixed device concrete structure be：Including be sequentially provided with central axis connection suction chamber,
Cavum laryngis and diffusion chamber, gas inlet end structure are formed with nozzle, and the nozzle is stretched into suction chamber, and the other end of air inlet, which is located at, calms the anger
Outside water premixed device, the side of the suction chamber is provided with inlet, and the inlet corresponds to nozzle bottom, the diffusion chamber it is another
One end is the port of export of water premixed device of calming the anger.
Moreover, the shower nozzle is fire-fighting SL-F600-7/G4.5DN20 fine mist spray heads.
The advantages of the utility model and have the beneficial effect that：
1st, this low pressure water and the united fine water mist fire-extinguishing system of chemical gas extinguishing chemical, clean chemical extinction using gas is combined
With effective combination of the respective advantage of two kinds of fire-fighting modes of fine mist fire-fighting, efficient, quick, clean fire extinguishing can be not only realized,
Fire scene temperature can also be effectively reduced, poisonous, corrosive gas the concentration such as HF in space of putting out a fire.
2nd, this low pressure water and the united fine water mist fire-extinguishing system of chemical gas extinguishing chemical, water system are normal fire fighting supply
Low pressure water, shower nozzle is fire-fighting SL-F600-7/G4.5DN20 fine mist spray heads, and shower nozzle is not easily blocked, to water quality requirement reduce；
Than existing heavy pressure fine spray more carefully, evenly, effective range is bigger, and extinguishing effect is more preferably for caused water mists particle diameter.
3rd, this low pressure water and the united fine water mist fire-extinguishing system of chemical gas extinguishing chemical, fire extinguishing system structure design is unique,
Simple and practical, the initial fire disaster that can be applied not only to the large spaces such as in general market, office space, factory building, warehouse is rescued
Shield, non-conductive additionally, due to clean chemical gas extinguishing agent, water droplet is small, and the system can also be applied to small distribution
The fire extinguishing protection in the electronic apparatus places such as computer room, cable appliance cabinets and computer communications equipment room.
