Abstract
The utility model provides a kind of spark and pressure detection dust fire-extinguishing explosion suppression device, and the spark and pressure detection dust fire-extinguishing explosion suppression device are using 4 spark detectors, shock wave pressure sensor as fire or explosion detection means: its structure is that spark detector, shock wave pressure sensor, water atomizing nozzle and explosion suppression bottle are provided on dust air draft pipe；Fire water is connected above water atomizing nozzle, and solenoid valve is provided in fire water.The utility model effectively increases fire-fighting efficiency, has saved cost, improves system to the reliability of spark or explosion detection.
Description
Technical field
The utility model relates to dust explosion risk place explosion-protection equipment fields, and in particular to a kind of spark and pressure are visited
Survey dust fire-extinguishing explosion suppression device.
Background technique
Dust at present explosion hazard area is mainly explosion venting device, explosion isolation device with explosion-protection equipment, due to there is spark
Or explosion time cannot actively take measures, and often result in the generation of explosion, although reducing the destructive power of explosion to a certain degree,
It cannot prevent from exploding.Thus in order to make dust explosion danger field meet the " dust that national Administration of Work Safety Supervision 2017-03-01 is formally implemented
Explosion hazard area dust pelletizing system technical specification of security " it requires, existing dust explosion risk place air draft pipe is changed
Dress；Firmly prevention dust explosion is the emphasis that we pay close attention to.
Utility model content
For above situation, the purpose of this utility model is that: a kind of spark is provided and the fire extinguishing of pressure detection dust is datonation-inhibition
Device makes it detect that then starting explosion suppression bottle inhibits explosion immediately for fire group or shock wave, while taking the fire suppression measures of water spray,
To which dust explosion be prevented trouble before it happens.
To achieve the above object, technical solution adopted in the utility model is: providing a kind of spark and pressure detection powder
Dirt fire-extinguishing explosion suppression device, the spark and pressure detection dust fire-extinguishing explosion suppression device are passed using 4 spark detectors, shock wave pressure
Sensor is as fire or explosion detection means: its structure is that spark detector, impact wave pressure are provided on dust air draft pipe
Force snesor, water atomizing nozzle and explosion suppression bottle；Fire water is connected above water atomizing nozzle, and electromagnetism is provided in fire water
Valve；Wherein shock wave pressure sensor, two spark detectors are mounted on before water atomizing nozzle, explosion suppression bottle at about 10m ~ 20m,
For detecting spark or explosion, other two spark detector is mounted on about 3m ~ 5m after water atomizing nozzle, explosion suppression bottle；For supervising
Survey fire extinguishing or effectiveness of explosion suppression.
The spark detector is adjusted the distance at 0.5 meter, the 1mm size spark response time is less than 1ms, is rolled into a ball to fire or explosion
Response time is less than 0.5ms；Shock wave pressure sensor is less than 0.5ms to the explosion wave response time.
It such as detects spark but does not explode, controller is immediately controlled solenoid valve and carries out quick sprinkling fire；Such as detection
To fire group, explosion or shock wave, then controller starts explosion suppression bottle inhibition explosion immediately, while taking the fire suppression measures of water spray.
This spark and pressure detection dust fire-extinguishing explosion suppression device are protected with the control device of dust pelletizing system simultaneously to be interlocked.
The beneficial effects of the utility model are: using spark detector, shock wave pressure sensor as fire or explosion
Detection means can distinguish spark and explosion；It spark but does not explode only, carries out quick sprinkling fire immediately；Detect fire
Then starting explosion suppression bottle inhibits explosion immediately for group's (explosion) or shock wave, while taking the fire suppression measures of water spray；Improve fire extinguishing effect
Rate has saved cost, effectively increases system to the reliability of spark or explosion detection.
Detailed description of the invention
Fig. 1 is spark and pressure detection dust fire-extinguishing explosion suppression device fitting arrangement；
Fig. 2 is spark and pressure detection dust fire-extinguishing explosion suppression device functional block diagram；
In figure: 1, dust air draft pipe；2, shock wave pressure sensor；3, spark detector；4, solenoid valve；5, water atomization
Nozzle；6, explosion suppression bottle.
Specific embodiment
As shown in Figure 1, 2, the utility model provides a kind of spark and pressure detection dust fire-extinguishing explosion suppression device, structure are
Spark detector 3, shock wave pressure sensor 2, water atomizing nozzle 5 and explosion suppression bottle 6 are provided on dust air draft pipe 1；Water
Fire water is connected above atomizer 5, and solenoid valve 4 is provided in fire water；Wherein shock wave pressure sensor 2, two
Spark detector 3 is mounted on before water atomizing nozzle 5, explosion suppression bottle 6 at about 10m ~ 20m, for detecting spark or explosion, in addition two
A spark detector 3 is mounted on about 3m ~ 5m after water atomizing nozzle 5, explosion suppression bottle 6；For monitoring fire extinguishing or effectiveness of explosion suppression.
The utility model uses spark detector, shock wave pressure sensor as fire or explosion detection means, can area
Sparkle-distributing and explosion；It spark but does not explode only, carries out quick sprinkling fire immediately；Detect fire group, explosion or impact
Then starting explosion suppression bottle inhibits explosion to wave immediately, while taking the fire suppression measures of water spray；Fire-fighting efficiency is improved, cost has been saved,
System is effectively increased to the reliability of spark or explosion detection.
