[Technical field]

[0001] The present invention relates to a TSP real-time detection device, and more particularly to a TSP real-time detection device for thermal power plant environments. [Background technology]

[0002] TSP (Total Suspended Particles) real-time detection devices are mainly used to monitor the concentration of total suspended particulate matter in the air. These devices usually use the principle of light scattering to measure the concentration of particulate matter, capture the light scattering phenomenon in particulate matter through the built-in sensor, and then calculate the number of particulate matter.

[0003] In existing thermal power plants, a large amount of exhaust gas is generated when burning coal and other fossil fuels, so it is necessary to detect it using TSP real-time detection equipment. The general method is to collect air samples from the environment through a sampling unit, detect the concentration of suspended particulate matter in real time through a sensor, receive the signal of the detection sensor through a data processing unit, and perform data analysis, processing and storage.

[0004] When detecting the environment of a thermal power plant, it is necessary to use a fan to suck in air samples from the surrounding environment and transport them to a detection sensor to detect the particulate matter concentration. However, the fan generates vibrations during operation, and after long-term use, a large amount of particulate matter is adsorbed on its inner walls, which are then sucked into the detection sensor, affecting the real-time detection results of the TSP.
