Problems solved by technology
The problem that may exist in the above patent is that the waveform sequence of high-concentration particles will occupy the entire time period, so that the system cannot recognize the concentration or the image cannot be segmented and recognized. This is a common problem with instruments based on the principle of conventional particle counters.

The invention discloses a novel smoke measuring device and method. The measurement device includes a light source, a measurement chamber, an optical signal detection module, and an optical signal processing unit; the measurement chamber is mainly composed of a window, an optical trap, a particle measurement area, an emission optical path, and a scattering optical path; the light source is placed on the front of the window, and the optical signal detection module It is placed at the back end of the scattered light path to form a typical light scattering measurement optical path system; the optical signal detection module is mainly composed of a focusing lens and an optical signal sensor; the optical signal sensor is connected to the optical signal processing unit; the optical signal processing unit is used to The received optical signal is processed to obtain the intensity signal and pulse signal, and then analyzed to obtain the smoke concentration. The device of the invention is simple in structure and low in use cost, and the measurement method adopts intensity signal and pulse signal two-phase multi-type signal combined analysis and processing to realize accurate and reliable measurement of smoke concentration.
Description
technical field [0001] The invention belongs to the technical field of environmental detection equipment, and in particular relates to a smoke and dust measuring device and method. Background technique [0002] In a modern industrial society, with the development of the world economy and the adjustment and transformation of the industrial structure, the environmental pollution caused by industrial boilers, power plant boilers and industrial kilns and other pollution sources has become more and more prominent. control. With the implementation of the domestic "ultra-low emission" transformation, the emission of smoke and dust from domestic pollution sources presents a combination of low concentration and high humidity, making online monitoring more difficult. The existing mainstream online monitoring products adopt high-temperature extraction sampling and light scattering measurement schemes. The high-humidity smoke after sampling is pretreated by high-temperature gasificatio...
