Description
Technical field
The invention belongs to technical field of fire control, more particularly, to a kind of hexafluorobutene gas extinguishing system.
Background technology
The mode of the single startup of generally use, structure are more multiple when starting in existing fire extinguishing system for extinguishing chemical bottle group
It is miscellaneous, it is cumbersome, fire extinguishing be to be formed total flooding speed it is slow.Meanwhile existing extinguishing chemical generally use heptafluoro-propane, hexafluoro third
Alkane, fluoroform etc., although these extinguishing chemicals can reach preferable extinguishing effect, its Global Greenhouse Effect latent energy value GWP
Compare high, it is difficult to meet environmental requirement now.
The content of the invention
The present invention starts rapid, energy-saving and environment-friendly hexafluorobutene gas to overcome the deficiencies of the prior art and provide one kind
Fire extinguishing system.
To achieve these goals, the present invention uses following technical scheme：A kind of hexafluorobutene gas extinguishing system, including
Extinguishing chemical bottle group, supply unit, releasing unit and start unit, the supply unit include the conveying being connected with extinguishing chemical bottle group
Pipeline, the afflux pipeline being connected with transfer pipeline and selector valve；It is described release pipeline include discharge conduit and with the discharge conduit
Connected atomizer；The start unit includes the driving pipeline for starting controlling switch and being connected with the extinguishing chemical bottle group；
There is extinguishing chemical in the extinguishing chemical bottle group, the extinguishing chemical is hexafluorobutene.The present invention is provided with driving pipeline, avoids
Starting switch is respectively provided with each extinguishing chemical bottle, structure is more simple, and operation is more easy during startup；Traditional hexafluorobutene is used for
In the fields such as foaming agent, refrigerant and solvent, now hexafluorobutene is used into extinguishing chemical field first, since hexafluorobutene disappears
Ozone latent energy value ODP=0 is consumed, Global Greenhouse Effect latent energy value GWP=2, environmental-protecting performance is very good, and high degree protects ozone
Layer and ecological environment；And the stable chemical performance of hexafluorobutene, so that not perishable fire-extinguishing apparatus, can not only extend making for system
It is also more convenient in storage with the service life；Meanwhile hexafluorobutene is at normal temperatures liquid, and it is filling to be easy to extinguishing chemical；Spurting
When, hexafluorobutene can fast endothermic, be easy to vaporize so that agent application evenly, improve extinguishing effect.
Further, the start unit further includes the driving bottle being connected with the driving pipeline, and the startup control is opened
Close and be arranged on the driving bottle；Driving bottle can need to only control driving bottle after starting by driving pipeline to drive extinguishing chemical bottle group
It is turned on and off, it is easy to operate, it is easy to implement, it is fast starts speed.
Further, the extinguishing chemical bottle group includes active bottle and driven bottle, and the startup controlling switch is arranged on this actively
On bottle；Only need to control one of bottle in extinguishing chemical bottle group to start the startup that other bottles can be achieved, it is easy to operate, it is easy to
Realize, it is fast to start speed.
Further, the discharge conduit is connected by selector valve with the afflux pipeline, the driving pipeline and institute
Selector valve is stated to be connected；Discharge conduit may be configured as multiple, and the connection of discharge conduit and header is controlled by selector valve, so that
When fire occurs for different zones, the discharge conduit in the region and afflux pipeline connection are only controlled, flexibility ratio higher, more intelligently
Change.
Further, the driving pipeline is equipped with low height of letting out and seals valve；Anti- locking system because extinguishing chemical bottle group is revealed
The situation of existing error starting, security performance are high.
Further, the driving pipeline is equipped with check valve；By the setting of check valve, realize that a driving pipeline can
Realize a variety of startup situations, system flexibility higher.
Further, the afflux pipeline is equipped with the first safe pressure relief device, and the extinguishing chemical bottle group is equipped with second
Safe pressure relief device；Overvoltage protection is carried out to afflux pipeline by the first safe pressure relief device, prevents afflux pipeline inner pressure mistake
Cause afflux pipeline explosion greatly；Overvoltage protection is carried out to extinguishing chemical bottle group by the second safe pressure relief device, prevents extinguishing chemical
Pressure is excessive and cause extinguishing chemical bottle group explosion in bottle group, enhances system security.
Further, the atomizer is equipped with spray-hole, and the single hole diameter of the spray-hole is 2mm-15mm；Injection
Hole aperture is smaller, so that agent application is apart from farther, while atomizing effect is more preferable, the extinguishing chemical in guard plot is distributed more
Uniformly.
Further, the atomizer is equipped with a decompression part；The drag losses of nozzle can be reduced, improves the spray of nozzle
Injection pressure, makes extinguishing chemical be spread faster in guard plot.
Further, the atomizer has round table-like ejection section, and the spray-hole is at least partially disposed in the injection
In portion；Under round table-like structure, part spray-hole will beat on inclined-plane, so that extinguishing chemical can be spread around, at the same time
The drag losses of nozzle can be also reduced, the injection pressure of nozzle is improved, extinguishing chemical is spread faster in guard plot.
In conclusion the present invention has the following advantages：There is provided driving pipeline, avoid and be all provided with each extinguishing chemical bottle
Put starting switch, when startup is easy to operate, and it is fast to start speed；Extinguishing chemical uses hexafluorobutene, and good environmental protection, it is equal to spurt effect
It is even, and not perishable fire-extinguishing apparatus, extend system service life.
