Problems solved by technology

The β-ray method directly measures the mass concentration without conversion and calibration. The measurement accuracy is high, and the measurement results are not affected by the characteristics of particle size, color, and chemical composition changes. However, the detection process takes a period of time and the measurement results cannot be released in real time.
Although t

Embodiment Construction

[0025] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0026] like figure 1 An on-line particle monitoring system based on the β-ray method and the light scattering method is shown, including a sampling unit 101, a detection unit 102 by the β-ray method, a detection unit 103 by the light scattering method, and a control unit 104;

[0027] The sampling unit 101 is used to collect flue gas from the flue;

[0028] The β-ray method detection unit 102 is used to measure the concentration of particulate matter in the flue gas by using the β-ray method;

[0029] The light-scattering detection unit 103 is used to measure the concentration of particulate matter in the flue gas by a light-scattering method;

[0030] The control unit 104 is used to control the β-ray method detection unit and the light scattering method detection unit, as well as data collection and processing;

[0031] The sampling unit 101 is respective...

Abstract

The invention provides an online particle monitoring system and method based on a beta ray method and a light scattering method. The system and method are used for precisely measuring the concentration of particles in smoke online in real time. The advantages of the beta ray method and the advantages of the light scattering method are combined, the reference standard of a beta ray method measuring result to a light scattering method measuring result is achieved through an internal reference method, and therefore the concentration of the particles in smoke is precisely measured online in real time. The measuring result is not influenced by the size, color, chemical constitution change and other characters of the particles, and the advantages of being high in precision, outputting figures in real time and the like are achieved.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and relates to an on-line particle monitoring system and method based on a beta ray method and a light scattering method. Background technique [0002] In accordance with the requirements of the national "Air Pollution Prevention and Control Action Plan", it is necessary to speed up the upgrading and transformation of existing dust removal facilities for coal-fired boilers and industrial furnaces to ensure that the concentration of particulate matter is stable and meets the emission standards. A series of standards such as the "Emission Standards of Air Pollutants for Thermal Power Plants" (GB13223-2011) promulgated by the state have reduced the concentration of particulate matter emissions in stationary source exhaust to 30mg / m 3 the following. At present, most units with a single installed capacity of more than 300,000 kilowatts have adopted the dust removal technology of elec...
