Problems solved by technology

[0003] However, the existing products are lacking in the protection of photoelectric tubes. First, the high temperature of the probe is caused by the thermal radiation generated by the combustion of a large amount of fuel in the furnace, which will affect the photoelectric conversion equipment, make the photoelectric conversion effect unstable, and affect the photoelectric tube. life span
In this way, under on-site working conditions, the probe is used in a high-temperature environment for a long time, and the photoelectric cell will soon be damaged due to high temperature.
[0004] Secondly, when the fuel burns in the furnace, a large amount of waste residue, smoke and dust will be generated, and even the fuel will drip onto the photoelectric cell due to incomplete combustion when burning oil, which is very inconvenient to clean. It is very troublesome to completely disassemble the probe
Many types of probes are designed with their own interfaces, and disassembly is relatively cumbersome

Abstract

The invention relates to a flame detection device, in particular to a flame detector probe. The device is characterized in that a quartz glass sheet is arranged between the protection sleeve cover of a photoelectric cell and the protection sleeve of the photoelectric cell; an annular gap is arranged between the quartz glass sheet and the protection sleeve of the photoelectric cell; an axial hole is arranged on the inner edge of one end of the protection sleeve of the photoelectric cell near the protection sleeve cover of the photoelectric cell; the axial hole is communicated with the inside space of the protection sleeve of the photoelectric cell and the annular gap; a rotary outlet with a slot structure is arranged in the protection sleeve cover of the photoelectric cell. The service life of a product is improved by the design of a cooling air course and the quartz glass sheet. The parts in the invention are mostly connected in a threaded way; therefore, the flame detector probe is conveniently dismounted and simply maintained.

Description

technical field [0001] The invention relates to a flame detection device, in particular to a flame detector probe. Background technique [0002] At present, the furnace body combustion monitoring probe in the chemical industry adopts the barrel probe method. Insert the barrel probe into the pre-designed interface to receive the ultraviolet light released when the flame burns, and convert the ultraviolet light into an electrical signal. [0003] However, the existing products are lacking in the protection of photoelectric tubes. First, the high temperature of the probe is caused by the thermal radiation generated by the combustion of a large amount of fuel in the furnace, which will affect the photoelectric conversion equipment, make the photoelectric conversion effect unstable, and affect the photoelectric tube. lifespan. In this way, under on-site working conditions, the probe is used in a high-temperature environment for a long time, and the photoelectric cell is quickly...
