Problems solved by technology

[0003] The existing fixed PM2.5 particle calibration instruments can only realize the calibration of the instrument to be sent to the laboratory, and cannot realize the on-site calibration of the online instrument
In addition, there are still large gaps in the field of PM10, dust and other large particle calibration devices, and low-concentration dust calibration devices. In particular, the current calibration method is still dominated by laboratory calibration. There is a lack of value transmission, and there is an urgent need for a mobile online calibration device

Abstract

The invention discloses an online raised dust calibration system and method, the calibration system comprises a vaporific particulate matter generation module, a dilution module for diluting vaporific particulate matters, a heating and drying module for heating and drying the diluted vaporific particulate matters, and an aerosol distribution module having a plurality of aerosol interfaces, the aerosol distribution module distributes dry dust aerosol to the aerosol interface, the aerosol interface is connected with a calibrated instrument, and the concentration measurement module is used for measuring the concentration of the dust aerosol flowing into the aerosol distribution module. The PID control module controls the dilution gas amount of the dilution module to the vaporific particles according to the data uploaded by the concentration measurement module so as to obtain the dust aerosol with the set mass concentration. The calibration system can realize on-site online calibration of the flying dust and environmental particulate matter monitoring instrument, and has the characteristics of portability and miniaturization.

Description

technical field [0001] The invention relates to the technical field of dust measurement and detection, in particular to an online dust calibration system and method. Background technique [0002] In the environmental online monitoring system, ensuring the accuracy of monitoring data, the uniformity of quantitative values ​​and traceability has become one of the key factors in rationally regulating the economic levers of pollution emission control, ensuring scientific and reasonable environmental protection law enforcement, and implementing particulate matter emission and pollution prevention and control. The construction of an automatic monitoring network for ambient air quality provides strong technical support for the real-time release of environmental quality data and early warning of air pollution. At the same time, the demand for dust measurement on construction sites with the characteristics of many scattered points and long distances poses new challenges to the tradit...
