Description

Technical Field

[0001] The utility model relates to the field of detectors, in particular to a flame photometric detector and an industrial on-line chromatograph using the same. Background Art

[0002] A flame photometric detector is a device specifically used to detect the presence of a flame. It works by detecting the specific spectrum and light intensity emitted by the flame.

[0003] A flame photometric detector usually consists of a combustion chamber, an air intake mechanism, an igniter, a transparent glass plate, a heat sink, a filter, and a photomultiplier tube. The combustible gas burns inside the combustion chamber, and then the light intensity passes through the transparent glass plate and the filter to the photomultiplier tube, and then cooperates with the chromatograph to detect the light intensity emitted by the flame.

[0004] When the combustible gas burns inside the combustion chamber, a certain amount of water vapor will be generated. Due to the temperature difference of the transparent glass plate, the water vapor will adhere to the transparent glass plate. By blowing air into the combustion chamber, the water droplets on the air-permeable plate can be volatilized and discharged. However, after the water droplets on the transparent glass plate volatilize, traces will be left on the transparent glass plate, which will affect the detection of the flame photometry. Therefore, it is necessary to regularly disassemble and clean the transparent glass plate. The transparent glass plate is installed between the combustion chamber and the housing of the photomultiplier tube, and it is usually locked by a threaded sleeve and a threaded cap. However, after multiple disassembly using the threaded sleeve and the threaded cap, the thread will slip. And when disassembling it, it is necessary to rotate the threaded cap a certain number of turns to disassemble and clean the transparent glass plate, which reduces the convenience of disassembling and cleaning the transparent glass plate.
