Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flue gas analyzers, and particularly relates to a high-temperature flue gas analyzer for rapid measurement. Background Technique
[0002] A flue gas analyzer is a device specifically used for measuring and analyzing various components in flue gas. Flue gas analyzers are mainly divided into two types: handheld and fixed, which are suitable for the requirements of different scenarios. Handheld flue gas analyzers are convenient to carry and operate, and are mainly used for environmental monitoring of small fuel and gas boilers' pollution emissions or near pollution sources. Fixed flue gas analyzers are usually installed near pollution sources for real-time online monitoring;
[0003] Since boiler flue gas often contains harmful substances such as sulfur dioxide, nitrogen oxides, and particulate matter, the emission of these substances into the atmosphere will pollute the environment, affect air quality, and even cause environmental problems such as acid rain and photochemical smog. Therefore, by detecting the composition and concentration of flue gas, pollutant emissions can be detected and controlled in a timely manner. When detecting the gas in the boiler with a flue gas analyzer, due to the high-temperature environment, the working stability and sensitivity of the sensor may be affected. Especially when the gas concentration is too high, the sensor may exceed its range, resulting in distorted readings or equipment damage. Therefore, the traditional method is to extract the flue gas in the boiler and cool it down, and then detect the flue gas with a handheld flue gas analyzer. Therefore, this detection method cannot achieve direct and rapid measurement of flue gas in a high-temperature environment quickly. Content of the Utility Model
[0004] The purpose of the utility model is to provide a high-temperature flue gas analyzer for rapid measurement, which can effectively solve the problems in the background technique.

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] As Figures 1-4 shown, a rapid measurement high-temperature flue gas analyzer provided by the present utility model includes an analyzer body 1 and a probe 2. The analyzer body 1 and the probe 2 are connected by a connecting pipe 3. The probe 2 further includes an operating handle 4. One end of the operating handle 4 is fixedly installed with a probe rod 21. One end of the operating handle 4 is also movably installed with a protective cover 5. An air guide pipe 6 is fixedly installed inside the protective cover 5. A micro fan 7 is fixedly installed at the bottom of the protective cover 5. The micro fan 7 further includes a machine cover 8. A motor 9 is fixedly installed inside the machine cover 8. A fan blade 10 is fixedly installed at the output end of the motor 9. And the motor 9 is electrically connected to the analyzer body 1 through a connecting wire. A sealing cone 11 is movably installed outside the protective cover 5.
[0024] As Figures 3-4 shown, a screw ring 20 is fixedly installed on the operating handle 4 at the outer peripheral position of the probe rod 21. By setting the screw ring 20 at one end of the operating handle 4, the rapid assembly of the protective cover 5 and the operating handle 4 can be realized.
[0025] As Figures 2-4As shown in the figure, an air inlet groove 12 is provided on one side of the bottom of the protective cover 5. An air inlet 13 is provided at the top inside the air inlet groove 12. An air outlet 14 is provided on one side of the top of the protective cover 5. A connecting seat 19 is fixedly installed on the side of the bottom of the protective cover 5 away from the air inlet groove 12. The protective cover 5 can protect the probe rod 21. At the same time, with the help of the air inlet groove 12, the air inlet 13 and the air outlet 14, the flue gas in the boiler can enter the protective cover 5. A connecting block 22 is fixedly installed at one end of the protective cover 5. The connecting block 22 is threadedly connected to the screw ring 20. One end of the air guide pipe 6 close to the air inlet groove 12 is fixedly installed with a diversion elbow 15, and a diversion plate 16 is fixedly installed on the outside of the diversion elbow 15. A sealing plate 17 is also fixedly installed on the outside of the air guide pipe 6. Through the cooperation of the air guide pipe 6 and the micro fan 7, the external air can be mixed with the flue gas entering the protective cover 5, so as to dilute the flue gas, so that the flue gas can be directly detected in the furnace body through the probe rod 21.
[0026] As shown in Figure 4, a connecting seat 19 is fixedly installed on the top of the machine cover 8. The connecting seat 19 is fixedly installed at the bottom of the fixed seat 18, and the inner cavity of the machine cover 8 is communicated with the inner cavity of the air guide pipe 6.
