Embodiment Construction

[0017] In order to solve the problems of high cost and low detection accuracy of traditional on-line monitors, an on-line monitor with low price and high detection accuracy is provided.

[0018] Such as figure 1 As shown, the online monitoring instrument of the preferred embodiment of the present invention is used for online monitoring of air quality. The on-line monitor includes an infrared light source 100 . The infrared light source 100 includes silicon carbide rods 110 . The silicon carbide rod 110 includes two electrodes, and the two electrodes are used to connect the silicon carbide rod 110 to a closed circuit of a power supply.

[0019] The above-mentioned on-line monitor uses silicon carbide rod 110 as the radiation light source. The silicon carbide rod 110 has a small resistance value, and under normal power-on conditions, it is similar to black body radiation and has a large radiation power density, which helps to improve the monitoring accuracy of the on-line moni...

Abstract

The invention relates to an online monitoring instrument, which is used for the online monitoring of air quality, and comprises an infrared light source. The infrared light source comprises a silicon-carbon rod, wherein the silicon-carbon rod comprises two electrodes, and the two electrodes are used for the silicon-carbon rod to access a closed loop of a power supply. The silicon-carbon rod is used as a radiation light source, the silicon-carbon rod has a small resistance value; and the silicon-carbon rod has a function similar to the blackbody radiation under the electrified normal working situation, and the radiation power density is large, so the monitoring precision of the online monitoring instrument can be improved. At the same time, raw materials for producing the online monitoring instrument are inexpensive and are simple to process and mold, so the cost is low, and the online monitoring instrument is easy to popularize.

Description

【Technical field】 [0001] The invention relates to the field of air quality monitoring, in particular to an online monitor for air quality monitoring. 【Background technique】 [0002] Environmental pollution has become a major issue of worldwide concern. With the development of industrial economy and the aggravation of air pollution, ambient air quality monitoring has become a very difficult task in today's world. Air quality monitoring requires accurate and stable monitoring instruments to meet the needs of the development of modern environmental monitoring. [0003] The non-dispersive infrared method online monitor has become the main method for monitoring carbon monoxide, carbon dioxide and sulfur dioxide in the air due to its high accuracy and sensitivity, and the infrared light source is one of the core components of the non-dispersive infrared method online monitor. Good or bad directly affects the working performance of the whole instrument. As far as the traditional...
