A Microbubble Static Stereo Imaging Observation Device

Abstract

A static three-dimensional imaging observation device for microbubbles, including an observation tank connected to the contact area to introduce water containing bubbles, the observation tank is a terrace structure with a built-in heat exchange coil, one end of the heat exchange coil is connected to a discharge pipe, and the discharge pipe is discharged The pipe is suspended above the waste liquid tank, and the medium is discharged in a non-submerged outflow manner. The other end is connected to one end of the tee, and the other two ends of the tee are respectively connected to the instant water heater and the liquid nitrogen bottle through a check valve and a stop valve. Observe The slot is placed obliquely, the light source is located on the side of the upper bottom, a filter plate is placed between the light source and the observation slot, cameras are installed on the lower bottom side and the waist side of the observation slot, and a magnifying glass is placed between the camera and the observation slot. It is connected to the host computer through a cable to process and calculate the collected images; the invention uses liquid nitrogen to convert the liquid containing bubbles from dynamic to static, which overcomes the difficulty of focusing when dynamically collecting information in the traditional imaging method, and eliminates the overlapping of projections caused by bubbles. Due to the calculation error caused, the bubble size can be accurately measured.

Description

technical field [0001] The invention belongs to the technical field of advanced sewage treatment, and in particular relates to a static three-dimensional imaging observation device for microbubbles. Background technique [0002] As an advanced treatment process for urban sewage, the ozone air flotation process combines ozone oxidation technology and air flotation separation technology to simultaneously complete demulsification, flocculation, solid-liquid separation, color removal, smell, taste, disinfection, etc. in one operating unit. multiple processes. Bubble size is an important factor affecting the treatment effect of the process. Therefore, it is of great significance to measure the bubble size and explore the corresponding bubble size under the optimal treatment effect for process application. In the air flotation contact area, in order to better contact the air bubbles with the flocs, the volume of the area is limited, resulting in an increase in the air bubble dens...
