Description
Technical Field
The invention relates to the technical field of fire monitoring auxiliary devices, in particular to a fire detection device and a using method thereof.
Background
It is known that substances, when burnt, produce visible or invisible light radiation in conjunction with the production of smoke and the release of heat. The photosensitive fire detector is also called a flame detector, and is used for responding to the optical characteristics of a fire, namely the light intensity of flame combustion and the flicker frequency of the flame. Depending on the light characteristics of the flame, there are two types of flame detectors currently used: one is an ultraviolet detector sensitive to shorter wavelength optical radiation and the other is an infrared detector sensitive to longer wavelength optical radiation. The working principle of the ultraviolet photosensitive detector is as follows: two high-purity tungsten wire or molybdenum wire electrodes are arranged in the glass bulb of the ultraviolet photosensitive tube. When the electrodes are irradiated by ultraviolet light, electrons are emitted and accelerated in an electric field between the two electrodes. The accelerated electrons (kinetic energy carriers) collide with hydrogen and helium gas molecules in the glass bulb to be ionized, and chain reaction is generated to cause avalanche type discharge, so that the ultraviolet light tube is switched from off to on to output an alarm signal. The working principle of the infrared photosensitive detector is as follows: the infrared photosensitive detector detects fire by using infrared radiation and flashover effect of flame. Because the wavelength of the infrared spectrum is longer, the smoke particles absorb and attenuate ultraviolet light and visible light far weaker than the ultraviolet light and visible light with shorter wavelength, so that the infrared photosensitive element can still respond even if the infrared photosensitive element is away from flame for a certain distance in a fire scene with a large amount of smoke, and the infrared spectrum has the characteristic of short response time.
Because the place that needs to install fire detector is complicated changeable now, current sensitization formula fire detector can only be installed perpendicularly to installation face, if say in crooked space, install sensitization fire detector on the wall of one side its detection range is very little, can't really realize the effect of fire detection, current sensitization formula fire detector exists in the place that spatial structure is complicated sensing formula fire detector's detection range is very little, can't really realize fire detection.
