Abstract

The invention relates to a microorganism aerosol sampling device which comprises a microorganism solution atomization generation device, a compressed air gasification device, a microorganism aerosol generation device and a sampling vessel, wherein the microorganism solution atomization generation device is connected and mixed with the compressed air gasification device and then connected with the front end of the microorganism aerosol generation device; the sampling vessel is connected onto the tail end of the microorganism aerosol generation device. According to the invention, the microorganism solution atomization generation device, the compressed air gasification device, the microorganism aerosol generation device and the sampling vessel are adopted, and through arrangement of quincuncial spraying holes and refining spray nozzles, the generation quality of microorganism aerosol is ensured; through arrangement of a boosting cylinder, a primary filter cartridge and a pressure stabilization cylinder, the quality and precision of air obtained through compression of the compressed air gasification device are ensured, and the generation quality of microorganism aerosol is further ensured; a sampling film and normal saline are adopted for sampling, so that the sampling quality and sampling rate are ensured, and the sampling capacity is improved.

Description

Technical field [0001] The invention relates to a microbial aerosol sampling device, relates to the field of aerosol sampling, and belongs to the technical field of aerosols. Background technique [0002] Microbial aerosol is a colloidal system formed by a group of small and simple single-celled or close-single-cell organisms suspended in the air. The particle size is 0.01-100μm, generally 0.30μm. Microbial aerosol has 6 major characteristics: Source The heterogeneity, diversity of species, variability of activity, three-dimensionality of dissemination, regeneration of deposition, and widespread of infection. The activity of microbial aerosol has been in a state of change since the moment it is formed. Microbes in the air are closely related to human production and life. It can benefit humans, but also endanger human life and health. Therefore, research and monitor air microbes The concentration, type, distribution and change law of aerosol are of great significance. The resear...
