Abstract
The invention relates to a microbial aerosol sampling device, which includes a microbial solution atomization generating device, a compressed air gasification device, a microbial sol generating device and a sampling vessel, wherein the microbial solution atomizing generating device and the compressed air gasification device are connected and mixed Afterwards, it is connected to the front end of the microbial sol generating device, and the sampling vessel is connected to the end of the microbial sol generating device. The present invention utilizes a microbial solution atomization generating device, a compressed air gasification device, a microbial sol generating device and a sampling vessel. Shaped spray holes and fine spray nozzles ensure the quality of microbial aerosol generation. By setting up a booster cylinder, a primary filter cylinder and a pressure regulator cylinder, the quality and accuracy of the gas compressed by the compressed air gasification device are guaranteed to further ensure For the quality of microbial aerosol generation, the sampling film and physiological saline are used for sampling, which ensures the sampling quality and sampling rate, and improves the sampling capacity.
Description
technical field [0001] The invention relates to a microbial aerosol sampling device, relates to the field of aerosol sampling, and belongs to the field of aerosol technology. Background technique [0002] Microbial aerosol is a colloidal system formed by a group of tiny and simple single-cell or nearly single-cell organisms suspended in the air. The particle size is 0.01-100 μm, generally 0.30 μm. Microbial aerosol has 6 characteristics: source The heterogeneity of the species, the diversity of species, the variability of activity, the three-dimensionality of dissemination, the regeneration of deposition, and the extensiveness of infection. The activity of microbial aerosols has been changing since the moment it was formed. Microorganisms in the air are closely related to human production and life. It can not only benefit human beings, but also endanger human life and health. The concentration, type, distribution and changing law of aerosol are of great significance. The s...
