Abstract

The invention discloses a collector with a real-time monitoring function. The collector comprises a laser emission device, a fine particle collecting device and a laser receiving device, wherein the fine particle collecting device comprises a shell, a sampling channel and a grading channel; the sampling channel and the grading channel are separately arranged in the shell; the grading channel is used for firstly grading the particles for the gas entering into the shell; the bigger particles are drained from the grading channel; to-be-monitored fine particles enter into the sampling channel; a barrier plate is arranged in the sampling channel; a flow-guiding hole is arranged on the barrier plate; a second collecting unit for collecting the fine particles is arranged in the flow-guiding hole; the laser emission device is located right above the flow-guiding hole; a receiving unit of the laser receiving device is located right under the flow-guiding hole; a laser beam emitted from the laser emission device passes through the second collecting unit and then enters into the receiving unit of the laser receiving device; and a calculating unit of the laser receiving device is used for calculating the concentration of the fine particles collected on the second collecting unit according to a light intensity signal measured by the receiving unit.

Description

technical field [0001] The invention relates to the technical field of equipment for sampling particles in the atmosphere, in particular to a collector with a real-time monitoring function. Background technique [0002] With the development of industry, the level of particulate pollutants in the atmosphere is increasing. These particulate pollutants will absorb various harmful substances in the air that can damage the nervous system and cause cancer, and bring many negative effects to the environment and human health. How to classify and calibrate the particle size of the particulate matter in the atmosphere is the primary problem in the research and solution of atmospheric particulate matter pollution. [0003] People use the particle sampling system to obtain the corresponding level of particulate matter in the air, so as to effectively detect and analyze the air quality or pollution index. Usually, an impactor sampler is used to carry out particle size classification sam...
