Background
Industrial flame detectors are generally used in the following fields: in places with severe environments, such as chemical plants, oil production platforms, oil refineries and the like, the influence of water mist, oil stains and wind sand is large, and once the pollution touches a window of the flame detector, the fire detection performance of the flame detector is damaged or even completely lost. On one hand, in order to prevent the flame detector from being influenced by pollution, a flame detector manufacturer can increase the function of window pollution detection, and can report fault signals such as window pollution or light path shielding when the window is polluted to a certain degree so as to remind a customer to maintain the instrument; on the other hand, a flame detector manufacturer adds an external gas circuit to the flame detector to blow the window to prevent the window from being attacked by pollutants, and the advantage of doing so is to directly cut off the path of the pollutants to enable the window to be in a clean air environment.

However, the flame detector is usually made of a metal shell, and has good heat conductivity, so that in order to enable the window to reach a certain temperature, the heating power consumption is large, energy is wasted, and due to the error of the temperature sensor, the temperature of the window can be set to be above 5 ℃, and certain power consumption is increased.

In the present invention, the shield mounting section 1.1 may be fastened to the flame detector housing 13 by a screw thread, snap fit or interference fit. The protective cover functional section 1.2 is slightly contracted at the outer edge of the flame detector shell 13 and is far away from a window 15 of the flame detector 14, the fire measuring view field of the flame detector 14 cannot be blocked, an infrared sensor 16 and an ultraviolet sensor 17 are arranged between the window 15 and the flame detector 14, the infrared sensor 16 is matched with a first infrared light source 7.1 and a second infrared light source 7.3, the ultraviolet sensor 17 is matched with a first ultraviolet light source 7.2 and a second ultraviolet light source 7.4, the infrared sensor 16 and the ultraviolet sensor 17 are powered by a rechargeable battery 8, and the main control panel 9 is connected with the infrared sensor 16 and the ultraviolet sensor 17 through signal lines.
In the invention, the built-in wireless charging coil 10 and the rechargeable battery 8 supply power to the first infrared light source 7.1, the first ultraviolet light source 7.2, the second infrared light source 7.3 and the second ultraviolet light source 7.4, and the first infrared light source 7.1, the first ultraviolet light source 7.2, the second infrared light source 7.3 and the second ultraviolet light source 7.4 are all arranged at the outer side of the flame detector 14, thereby realizing electrical isolation without influencing the function safety and failure rate of the flame detector 14. When the window 15 is completely shielded, no light source signal exists, when the window is not shielded, the light source signal does not attenuate, and the recognition degree reaches 100%.
The flame detector protective cover can monitor the air quality in front of the window 15 in real time, and the dust sensor 6 can monitor dust, sand and atomized particles in the air, because the pollutants can absorb or block signals of flame, when the pollution degree detected by the dust sensor 6 exceeds a certain threshold value, the first fan 2.1 and the second fan 2.2 are opened, impurities in the air are filtered through the first filter cotton 4.1 and the second filter cotton 4.2, clean air is blown to the surface of the window 15, and pollution of dust and atomized oil is avoided, as shown in fig. 4.
When the dust sensor 6 detects that the air is clean, the first fan 2.1 rotates reversely to blow out impurities in the first filter cotton 4.1, and the second fan 2.2 at the opposite position opens the blowing window 13 to prevent the impurities in the first filter cotton 4.1 from polluting the window 15, as shown in fig. 5. After the operation for a period of time, the second fan 2.2 rotates reversely to blow out the impurities in the second filter cotton 4.2, and the first fan 2.1 at the opposite position opens the purging window 15 at the moment to prevent the impurities in the second filter cotton 4.2 from polluting the window 15, as shown in fig. 6. The above process is cycled until all the cotton filter cleaning is completed.
Weathered, moisture from the air tends to condense on the surface of the window 15 or form thin ice, which can degrade the fire detection field of the flame detector 14. Therefore, the temperature sensor 11 and the humidity sensor 12 in the present invention monitor the temperature and the humidity of the surface of the window 15, when the temperature is lower than the set value or the humidity is higher than the set value, the power supplies of the first infrared light source 7.1, the first ultraviolet light source 7.2, the second infrared light source 7.3 and the second ultraviolet light source 7.4 are turned off, the first heater 5.1 and the second heater 5.2 are turned on, and simultaneously the first fan 2.1 and the second fan 2.2 are turned on, so as to purge the window 15 with hot air, thereby preventing the moisture from condensing on the window 15, as shown in fig. 7.
In the invention, the light emitted by the first infrared light source 7.1, the first ultraviolet light source 7.2, the second infrared light source 7.3 and the second ultraviolet light source 7.4 can only reach the surfaces of the infrared sensor 16 and the ultraviolet sensor 17 through the window 15, so when the window 15 is polluted, the pollution degree of the window 15 can be judged linearly through the attenuation of the light, and the light intensity can be improved by additionally arranging the infrared light source and the ultraviolet light source, thereby improving the resolution ratio. And because the infrared light source and the ultraviolet light source are arranged outside the flame detector 14, precious space in the instrument is not occupied.
The main control board 9 of the present invention can monitor whether the flame detector 14 is working normally or not in real time. The flame detector 14 records a model of 'false fire', when the flame detector 14 identifies the 'false fire', the flow is the same as that of 'true fire', and finally, the purpose of self-detection of instrument fire detection is achieved by checking whether each 'flag bit' is in the state of alarming. The 'false fire' triggering mode can be realized through the main control panel 9, the signal of the red ultraviolet light source is modulated through the main control panel 9, the output signal of the red ultraviolet light source accords with the 'false fire' characteristic defined by a manufacturer, and the 'false fire' is identified by the flame detector 14, so that the instrument fire-detecting self-detection function of the flame detector 14 is realized. By switching the infrared light source and the ultraviolet light source at a certain frequency, the infrared sensor 16 and the ultraviolet sensor 17 can receive a false fire signal similar to 'flame', so that the flame detector 14 can identify the 'false fire' for performing the self-checking function of the instrument.
