Abstract

The invention discloses an infrared photoelectric flame detector. The infrared photoelectric flame detector comprises a shell; an ST178H infrared photoelectric sensor and a 16-bit high-precision microprocessor are installed in the shell, an infrared receiving head is arranged on the outer side face of the ST178H infrared photoelectric sensor and is in signal connection with the ST178H infrared photoelectric sensor, a rotary bolt is arranged at the bottom of the shell, a wiring tube is arranged at the bottom of the rotary bolt, a supporting frame is arranged on the side face of the shell and isfixedly connected with the shell through bolts, and a mounting plate is arranged on one side of the supporting frame and is welded to the supporting frame. Compared with an existing infrared multi-frequency flame detector, the infrared photoelectric flame detector has the advantages that the detection precision is high, the influence of ambient light interference is small, use is safe and reliable, and different needs of more occasions can be met.

Description

technical field [0001] The invention relates to the technical field of flame detectors, in particular to an infrared photoelectric flame detector. Background technique [0002] The flame detector is to detect the invisible light radiation that is visible or not in the atmosphere while producing smoke and releasing heat when the substance burns. According to the optical characteristics of the flame, there are three types of flame detectors used: one is an ultraviolet detector that is sensitive to ultraviolet radiation with a shorter wavelength in the flame; the other is an infrared detector that is sensitive to infrared radiation with a longer wavelength in the flame. detector; the third is a UV / IR hybrid detector that simultaneously detects both short-wavelength ultraviolet rays and long-wavelength infrared rays in flames. [0003] After searching, it was found that the invention of application number 201010580660.3 discloses an infrared photoelectric flame detector, the st...
