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.
