Detection device and detection method for air particulate matters

Abstract

The invention discloses a detection device and a detection method for air particulate matters. The device comprises a bearing box, a motor and a microscope, wherein a fluid director is fixed in the bearing box; a dust collection frame and a second filter screen are respectively arranged on the left side and the right side of a first filter screen; bearing seats are arranged between the dust collection frame and the first filter screen, between the first filter screen and the second filter screen, between the second filter screen and the third filter screen, and between the third filter screenand the fourth filter screen; and the microscope penetrates through the top of the bearing seat and is in threaded connection with a sleeve, an air outlet pipeline penetrates through the right side ofthe bearing box, and a control panel is placed in the top of the bearing box. According to the detection device and the detection method for the air particulate matters, the microscope and the control panel, the microscope can move up and down along with the bearing seat, suspended solids attached to the first filter screen, the second filter screen, the third filter screen and the fourth filterscreen can be observed and detected conveniently, observed and detected results are fed back to the control panel, and analysis is facilitated.

Description

technical field [0001] The invention relates to the technical field of air particulates, in particular to a detection device and a detection method for air particulates. Background technique [0002] Air particulate matter is the general term for all kinds of solid and liquid particulate matter existing in the atmosphere. All kinds of particulate matter are evenly dispersed in the air to form a relatively stable and huge suspension system, that is, the aerosol system. Therefore, atmospheric particulate matter is also called atmosphere Aerosol, aerosol is a multi-phase system, composed of particles and gases, usually seen dust, smoke, smoke, fog, haze, etc. all belong to the category of aerosol, in the process of detecting the composition of air particles, it is necessary to Use the detection device. [0003] The existing detection device is inconvenient to separate the particles in the air from the air layer by layer. The types of air particles are not comprehensive enough,...
