Embodiment Construction

[0026] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0027] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terms used herein in the description of the present invention are for the purpose of describing specific embodiments only, and are not intended...

Abstract

The invention relates to the technical field of environmental quality detection, and particularly relates to a dynamic generation device for microbial aerosol. The dynamic generation device comprisesan air inlet air filter, a monodispersion generator, a flow controller, a valve bank, a gas rectification device, an aerosol testing bin, an air outlet air filter, an air supply and a decontaminationgas generator, wherein one end of the air inlet air filter is connected with certain ends of the monodispersion generator and the flow controller respectively; the other ends of the monodispersion generator and the flow controller are connected with the valve bank respectively; one port of the valve bank is communicated with the gas rectification device; the gas rectification device is communicated with the upper part of the aerosol testing bin; the interior of the aerosol testing bin is divided into two parts of a testing area and a standard area; the bottom of the aerosol testing bin are connected with the air supply through the air outlet air filter. An aerosol sample which is stable in concentration can be continuously provided by utilizing a dynamic generation method and the randomness of a testing result is decreased.

Description

technical field [0001] The invention relates to the technical field of environmental quality detection, in particular to a dynamic generating device for microbial aerosol. Background technique [0002] Microbial aerosol refers to a stable dispersion system formed by using microorganisms as the dispersant and gas as the dispersant. Microbial aerosols exist in large quantities in human settlements. People usually use microbial sampling devices to fix microbial aerosols in the environment in a liquid phase dispersant or directly on the medium, and then complete the microbial aerosols in a certain environment. Quantitative evaluation of hazard levels. In the process of sampling device development, performance evaluation, parameter calibration, etc., the aerosol generating device should be able to provide microbial aerosol samples with a single type, uniform dispersion, and controllable concentration. [0003] Traditional aerosol generating devices usually place the aerosol mon...
