Abstract
The utility model provides a secondary combustion chamber, the exhanst gas outlet department installation infrared ray thermoscope of secondary combustion chamber, the infrared ray thermoscope level is fixed in the outer wall of secondary combustion chamber, its optical system extends to the inside of secondary combustion chamber. The infrared thermometer is positioned above or below the smoke outlet, and the horizontal center line of the infrared thermometer and the horizontal center line of the smoke outlet are positioned in the same vertical plane. The infrared thermometer of the utility model can accurately measure the actual temperature with small deviation; the infrared thermometer is not easy to damage and has low cost.
Description
Technical Field
The utility model belongs to the technical field of the postcombustion chamber, concretely relates to postcombustion chamber.
Background
The thermocouple for the temperature measuring device of the existing secondary combustion chamber has the defects that the temperature of the secondary combustion chamber exceeds 1200 ℃ due to higher temperature and high heat value of some materials, the coking is easily formed in the secondary combustion chamber, the thermocouple is buried in the secondary combustion chamber, the heat conduction is insensitive, the actual temperature (lower) cannot be accurately reflected, the actual temperature is too high, and the rear-section equipment is influenced. Because the thermocouple material is made of pottery, also must not take out the back decoking after blowing out, only can follow and trade, the cost is very high.
SUMMERY OF THE UTILITY MODEL
To the not enough of above-mentioned prior art, the utility model provides a afterburner uses infrared radiation thermometer to replace thermocouple temperature measurement.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an infrared thermometer is installed at a smoke outlet of the secondary combustion chamber, the infrared thermometer is horizontally fixed on the outer wall of the secondary combustion chamber, and an optical system of the infrared thermometer extends into the secondary combustion chamber.
Has the advantages that: (1) the infrared thermometer can accurately measure the actual temperature, and the deviation is very small;
(2) the infrared thermometer is not easy to damage and has low cost.
Drawings
Fig. 1 is a schematic structural view of the present invention;
reference numbers in the figures: 1. a secondary combustion chamber; 2. a flue gas duct; 3. an infrared thermometer; 4. and a flue gas outlet.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in figure 1, a flue gas outlet 4 of a secondary combustion chamber 1 is connected with a flue gas pipeline 2, an infrared thermometer 3 is arranged above or below the flue gas outlet 4, and the horizontal central lines of the two are positioned on the same vertical plane.
The infrared thermometer 3 is composed of an optical system, a photoelectric detector, a signal amplifier, a signal processing part, a display output part and the like. The flame in the secondary combustion chamber 1 does not stop sending infrared radiation energy to the surroundings, and the energy is closely related to the surface temperature thereof according to the wavelength distribution. The optical system extends into the secondary combustion chamber 1 to gather target infrared radiation energy in a visual field of the secondary combustion chamber, and the size of the visual field is determined by optical parts of the thermodetector and the position of the optical parts. The infrared energy is focused on the photodetector and converted into a corresponding electrical signal. The signal is converted into the temperature value of the measured target after passing through an amplifier and a signal processing circuit and being corrected according to an instrument internal therapy algorithm and target emissivity.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
