Abstract

The present invention discloses an apparatus and method for testing spray atomization performance. The apparatus consists of a mechanical part, a camera shooting part, a control part and an image processing part. The mechanical part is used for performing motion of a thin-layer chromatography silica gel plate driven by a stepper motor to achieve spray droplet collection; the camera shooting part is used for colleting the images of the spray droplets fallen to the thin-layer chromatography silica gel plate; the control part is used for controlling the entire apparatus in the testing process; the image processing part comprises a PC terminal and a piece of image processing software installed in the PC, and is used for processing and analyzing the images of the spray droplets on the thin-layer chromatography silica gel plate collected by the camera shooting part. The apparatus has the advantages of simpleness, low cost and easy operation; the image processing method can process the images to obtain particle size and distribution uniformity of the spray droplets, and achieve multiple real-time measurements; the test and analysis results are more reliable and credible; and measurement at multiple locations within the space at a time can analyze the spatial density distribution of the spray effect.

Description

technical field [0001] The invention relates to the technical field of detection instruments, in particular to a spray atomization effect performance detection device and method. Background technique [0002] Spraying is the physical process of spraying a liquid into the surrounding gaseous medium through a nozzle to break it into fine droplets. During the formation of spray droplets, the total surface area of ​​the liquid is significantly increased due to the liquid being broken into a large number of droplets, so the contact area between the liquid and the surrounding gas medium will be significantly increased, so that the effect of the disinfectant in the surrounding gas medium will be therefore Improved. Performance parameters such as particle size, uniformity, and spatial density distribution of the atomized droplets of the spray device have a direct and important influence on the atomization effect of the disinfection spray device. The particle size, uniformity, and ...
