Device and method for measuring foam size distribution

Abstract

The invention discloses a device and method for measuring foam size distribution, and belongs to the technical field of foam testing devices. A light path conversion unit is arranged on the side portion of a foam collecting unit to refract light, a clear bubble distribution image is obtained through light refraction, distribution of bubble diameters can be conveniently tested, and a problem that a large number of background bubbles easily appear during microscope shooting is solved. According to the invention, the device comprises a foaming unit; a bubble collecting unit, wherein foam generated by the foaming unit is supplied to the bubble collecting unit; a light path conversion unit arranged at the side part of the bubble collecting unit; and an optical imaging unit which is arranged opposite to the light path conversion unit, wherein a bubble distribution image is obtained in the optical imaging unit after the light is refracted by the light path conversion unit.

Description

technical field [0001] The invention relates to the technical field of foam testing devices, in particular to a device and method for measuring foam size distribution. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] As an important substance in the chemical industry, foam has been widely used in many fields, such as secondary exploitation of petroleum, foam fire extinguishing, ore flotation, foam decontamination, and wastewater treatment. Among them, the stability of foam is in An important property in practical applications, the stability of foam refers to the persistence of the generated foam. In different application fields, the performance requirements of the foam are also different, and the foam with poor stability will increase the burst rate of the bubbles. From a macroscopic point of view, one main method is to characterize the stability ...

Problems solved by technology

[0005] The inventors have found that the widely used optical method in the laboratory often uses microscope technology to observe the morphological decay process of foam, but in practical applications, after using the above method to generate a certain volume and height of foam, when directly observed through a microscope, it is often because the lens Due to the limitation of focal length, a large number of background bubbles appear during shooting, resulting in blurred foam images; the size of the foam is relatively small and the foam structure is repeatedly stacked, it is often difficult to extract a clear foam image during image post-processing, which affects the follow-up Test of Foam Diameter Distribution
