Microcosmic characterization method for smoke aerosol particles in cellosilk surface accumulation process and capturing and shooting device

Abstract

The invention discloses a microcosmic characterization method for smoke aerosol particles in a cellosilk surface accumulation process. The microcosmic characterization method is characterized in that a microscope is used for performing image acquisition on cellosilk arranged in a smoke channel in an aerosol particle capturing process and then performing image processing, so that the microcosmic process that the aerosol particles are accumulated on the surface of the cellosilk is obtained. A used capturing and shooting device comprises the smoke channel, an observation window formed on the channel, and the microscope with a charge coupled device (CCD) camera, wherein a bracket for clamping the cellosilk is arranged in the channel; and one end of the smoke channel is connected with a smoke collection port, and the other end of the smoke channel is sequentially connected with a filter, a flowmeter and a vacuum pump. By using a smoke particle cellosilk adsorption microcosmic observation device, due to the image acquisition and the image processing, the microcosmic characterization that the smoke aerosol particles are continuously accumulated on the surface of the cellosilk is realized, so that the deep learning of the cellosilk capturing is facilitated; and an evaluation measure is supplied for the novel fiber development.

Description

technical field [0001] The invention belongs to the technical field of flue gas aerosol microscopic research, and in particular relates to a microscopic characterization method for the accumulation process of aerosol particles on the surface of fiber filaments and a special capturing and photographing device. Background technique [0002] In daily life, people will inevitably come into contact with various smoke aerosols, such as vehicle exhaust, factory waste gas, cooking smoke, cigarette smoke and other emissions from the combustion of combustion substances. At present, the problem of particle pollution is becoming more and more serious. Among them, PM10 particles are easily inhaled into the human respiratory tract, and PM2.5 particles can further enter the human body, which has become one of the important factors affecting the health of urban residents. [0003] Fiber filtration is one of the effective ways to effectively control the environmental pollution of flue gas ae...

AI Technical Summary

Problems solved by technology

For smoke aerosol particles such as cooking oil fumes, cigarette smoke and other aerosols, due to the strong viscosity of the particles, the particles are easily deformed when they interact with each other after the particles are enriched on the fiber surface, and the enrichment status of the particles on the fiber surface at different times is obtained. It will play an important role in in-depth understanding of the microscopic mechanism of fiber capture of flue gas aerosol particles, and has an important guiding role in the study of how to improve fiber adsorption efficiency or develop new fiber materials, but currently there is no effective characterization method in this regard
