Air particulate matter automatic monitoring system and monitoring method

Abstract

The invention discloses an air particulate matter automatic monitoring system and a monitoring method. The system comprises a cabinet body, a temperature-humidity controller and an intelligent controlsystem; a constant-temperature and constant-humidity box body is arranged in the cabinet body; a main sample disk, a secondary sample disk, a balance weighing device and a particulate sampler are arranged in the constant-temperature and constant-humidity box body; the sampling pipe connected with the particulate sampler is arranged at the top of the cabinet body; a sample-changing manipulator isarranged between the main sample disk and the secondary sample disk; sample conveying manipulators are arranged among the main sample disk, the balance weighing device and the particulate sampler; a sample disk isolation hood for separating the secondary sample disk from the constant-temperature and constant-humidity box body is arranged at the external of the secondary sample disk; a side-openingwindow is arranged at one side of the secondary sample disk on the cabinet body, and a main window is formed in the front of the cabinet body. The monitoring system disclosed by the invention integrates the weighing, the balancing, the sampling and the data processing; the manual intervention is avoided, the weighing accuracy and the stability are improved, the labor intensity is effectively relieved, and the timeliness is guaranteed.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to an automatic monitoring system and monitoring method for air particulate matter. Background technique [0002] Air particulate matter refers to solid or liquid particulate matter dispersed in the air. According to its particle size, it can be divided into total suspended particulate matter (TSP) with an aerodynamic diameter less than or equal to 100 μm and total suspended particulate matter (TSP) with an aerodynamic diameter less than or equal to 100 μm. Respirable particulate matter (PM10) of 10 μm. Inhalable particulate matter can be subdivided into fine PM2.5 (aerodynamic diameter less than or equal to 2.5 μm) and coarse particles (aerodynamic diameter between 2.5 μm and 10 μm). [0003] A large amount of particulate matter falls on plant leaves and affects plant growth, and falls on buildings and clothes to stain and corrode. Particles with a part...

Problems solved by technology

However, the sampling and weighing of the previous gravimetric method required manual operations. The procedure was cumbersome and time-consuming, and the test results could not be given immediately, and errors were likely to occur during the transportation process from sampling to weighing.
