Detailed Description
As shown in fig. 1, the present embodiment provides a torch incandescent lamp flame monitoring device, including an incandescent lamp 1, a torch tower 2, a fuel line 3, a pilot line 4, a vibration sensor 5, and a processor 7. The pilot burner 1 is installed on the top of the torch tower 2, the bottom of the pilot burner 1 is connected with a fuel pipeline 3 and a pilot pipeline 4, fuel gas is introduced into the fuel pipeline 3, the pilot burner 1 is always in a burning state and is used for igniting a torch in an accident state, and the pilot pipeline 4 is used for igniting the pilot burner 1. The IEPE type vibration sensor 5 is selected as the vibration sensor 5, and the frequency response range of the vibration sensor 5 is 10kHz-100 kHz. The vibration sensor 5 is connected to a processor 7 via a signal cable 6. The pilot lamp 1 will send out the sound wave signal when burning and producing the flame, and vibration sensor 5 receives the sound wave signal that pilot lamp 1 burns and produces, and the signal transmission treater 7 of will changing into the signal of telecommunication to the sound wave signal. The processor 7 analyzes the sound wave electric signals collected by the vibration sensor 5, extracts the flame combustion noise electric signals of the pilot burner 1, and the processor 7 compares the noise electric signals with a set value to judge the flame combustion state of the pilot burner 1. When the noise electric signal value is larger than the set value, the pilot burner 1 is judged to be in a burning state; and when the noise electric signal value is smaller than the set value, judging that the pilot burner 1 is in a turned-off state. The sound wave is energy, and is not easily buffered and consumed because the solid structure is compact, so the sound wave generally propagates in the solid at a higher speed and a longer distance than in the air. The vibration sensor 5 can be arranged on the torch tower 2, the fuel pipeline 3 and the ignition pipeline 4, so that the vibration sensor 5 can quickly receive sound wave signals generated by the combustion of the pilot burner 1, and can avoid the interference of other noise signals in the air. The vibration sensor 5 of this embodiment is installed in the ground position of keeping away from the pilot light 1 on the pilot line 4, and the pilot line 4 receives external interference fewly, and the vibration sensor 5 can more accurately receive the sound wave signal that the pilot light 1 burns and produce. In addition, the vibration sensor 5 is installed on the ignition pipeline 4 and is far away from the ground position of the pilot lamp 1 by about 100 meters to 150 meters, the vibration sensor 5 is convenient to install, and the vibration sensor 5 is far away from the pilot lamp 1, so that the vibration sensor 5 is prevented from being high in temperature and corroded, and the service life is long. The processor 7 is disposed in a control room about 300 to 500 meters away from the vibration sensor 5, facilitating remote control of flame condition monitoring by an operator in the control room. In the flame monitoring device for the torch incandescent lamp, the processor 7 is in signal connection with a Distributed Control System (DCS) to realize monitoring, alarming, interlocking control of the flame state and automatic ignition of the incandescent lamp 1. Compared with the traditional torch incandescent lamp flame monitoring technology, the torch incandescent lamp flame monitoring device is installed at the positions of the torch tower frame 2, the fuel pipeline 3, the ignition pipeline 4 and the like on the ground, and especially installed on the ignition pipeline 4 on the ground, so that the problems that the existing flame monitoring technology is long in response time, short in service life, high in interference caused by weather conditions and the like can be effectively solved, and the torch incandescent lamp flame monitoring device has the advantages of being simple in structure, convenient to install, long in service life, low in cost, high in flame state monitoring response speed, accurate and reliable in flame monitoring result and the like.
