Technical Field
The utility model belongs to the technical field of the flame is shot, especially relate to a flame shoots device based on image intensifier.
Background
When any fuel is burnt, light waves such as ultraviolet rays, visible rays and infrared rays are radiated outwards to different degrees. The wavelength band of the radiated light is different when the fuel is different; the combustion conditions are different, and the detectability of flame radiation light waves on each wave band is also different. The spectrum of the flame spans three frequency spectrum bands of ultraviolet rays, visible light and infrared rays, wherein the wavelength of the ultraviolet rays is distributed in a wave band of 10-380 nm, the wavelength of the visible light is distributed in a wave band of 380-700 nm, and the wavelength of the infrared rays is distributed in a wavelength range larger than 700 nm. Since the visible spectrum detection is greatly disturbed by ambient light, more visible light information needs to be acquired in combination with the flame image.
The burning characteristic of the flame is researched and known, so that people can find the fire phenomenon in the brewing as soon as possible, and the harm is reduced; the working state of an internal combustion engine, a power station boiler and the like can be monitored in real time, the working efficiency is further improved, and the pollution to air is reduced; the method is favorable for developing a flame matching detector with quick response and improving the performance of the full-automatic fire extinguishing and explosion suppression device in the armored vehicle. At present, flame research mainly comprises a spectral method and an image method, the spectral method is divided into ultraviolet, visible light and infrared detection according to different detection wave bands of a spectrometer, and due to the limitation of single equipment, spectral research can be carried out only in a certain wave band range; the image method is to analyze information such as flame temperature and burning rate by collecting images of burning flames through a high-speed camera, and the method only utilizes visible light information of flames and has limited research content.
The important physical phenomena of the flame are: radiation (including heat and light radiation), temperature, propagation speed, flicker frequency, and the like, and methods for flame analysis have been developed for the analysis of the above phenomena. The most original analysis method is only a temperature analysis method or a combustion speed analysis method from the temperature viewpoint. The combustion velocity refers to the moving velocity of the parallel front flame surface in the adjacent unburned gas along its normal direction. The combustion speed is a basic constant of combustible mixed gas, which not only has great practical significance for considering the stability of flame, but also has great theoretical value in the aspect of researching the propagation theory of flame.
