Description
Technical field
The utility model relates to a kind of fire extinguishing every explosion suppression device, particularly relates to a kind of gas that is applicable to and puts out a fire every datonation-inhibition active explosion suppression device.
Background technology
Fire is one of crushing disaster, and its direct economic loss is huge, and the frequency of generation occupies first of the various disasters.It is environmental pollution not only, and causes disruption of ecological balance, even has caused great casualties and property loss.Gas fire extinguishing can also be in sensitive, fast, reliably the Mars stage every explosion suppression device and detect in advance danger signal before blast also occurs, and it is put out.
The flame proof technology that present China generally promotes the use of is the various passive explosion isolation device that comes in the first generation isolated blast water bottle basis improvement of 20th century, be subject to the restriction of working mechanism, its sphere of action and effect are very limited, and also are subjected to directly affecting of environment and human factor in actual use.
Flame during the different fuel burning has different radiation spectrums, can obtain wave spectrum and the intensity distributions of specific flame by measurement and analyzing radiation spectrum.Utilize fiber spectrometer can measure different flame radiation spectrum under the different condition, the sensor of studying under the different Fire Conditions detects spectral region.The radiation spectrum of the inner gas of coal mine roadway and coal dust intermixture burning, although also have a large amount of solids in the pulverized coal flame, the infrared radiation wave spectrum of major effect flame is on the almost not impact of ultra-violet radiation wave spectrum.Under the hot environment of flame, the radiation spectrum of solids mostly is continuous spectrum, and the emission spectrum of gas molecule mostly is emission or selective absorption of segmentation.Measure and find, when gas burns with coal dust mixing combustible, flame spectrum is the distribution of the radiation intensity of flame in whole wavelength band, the emission spectrum of gas pulverized coal flame is across ultraviolet, visible light and the electromagnetic radiation wave band such as infrared, and these electromagnetic radiation mainly are that the molecule by combustion product discharges under the high temperature excited state.
The spectrum that can observe flame in ultraviolet band is the band spectrum of NO, also has in addition the emission spectra of the metallic atom in the flame.Because atmosphere is to the absorption of short wave ultraviolet, the ultraviolet ray that makes solar radiation shine earth surface only has wavelength greater than the long wave ultraviolet of 0.29 μ m, and the shortwave radiation below the 0.29 μ m is few at the earth's surface;on the face of the globe.Simultaneously in view of the actual environment in the coal mine roadway and fire detection requirement, we are regional as UV detection with the wave band below the 0.29 μ m in the design of flame detector, the ultraviolet radiation sensor that is operated in this detection zone does not respond solar radiation, thereby has avoided the interference of natural light and ordinary light source.
Active of the present utility model is ultrahigh speed active explosion suppression device every explosion suppression device, and this device has breakthrough in gas and coal-dust explosion Prevention Technique, and technical advantage is obvious.
