Abstract:
An ultrafine bubble cleaning apparatus uses a liquid containing ultrafine bubbles having a size of less than 30 nm to rinse fine particles adhered to soil, sand, etc. to separate and collect the fine particles. The ultrafine bubble cleaning apparatus includes a water tank-shaped reservoir, a stirring device, a supernatant discharge device including a pump for discharging a supernatant of the liquid in the reservoir, and a sedimentation extraction device. Substances are loaded into the ultrafine bubble-containing liquid stored in the reservoir, and the ultrafine bubble-containing liquid is repeatedly brought into contact with the surface of the substance using the stirring device. When ultrafine bubbles get into a space between fine metal particles adhered to the surfaces, cracks, and pits of the substances to be cleaned (including metal ions) and fine particles of organic substances including a solvent, a chemical, and oil, the fine particles are separated and floated.

Claim (Index 8):
An ultrafine bubble cleaning apparatus comprising:\n an ultrafine bubble-containing water production device swirling a water containing ultrafine bubbles having a size of 3 \u212b or more and less than 10 \u212b and bubbles larger than the ultrafine bubbles to concentrate a part thereof that contains the ultrafine bubbles and has a relatively large specific gravity outside a swirling flow, and concentrate a part thereof that contains bubbles larger than the ultrafine bubbles and has a relatively small specific gravity to a central part of the swirling flow followed by discharge, so as to produce an ultrafine bubble-containing liquid concentrated to outside the swirling flow; a reservoir configured to be capable of containing raw water in which fine droplets of an organic substance, are dispersed; an ultrafine bubble-containing water supply device configured to supply an ultrafine bubble-containing water produced by the ultrafine bubble-containing water production device to raw water of the reservoir; a stirring device that is provided in the reservoir and configured to stir the raw water stored thereinside; and a floated substance and liquid discharging device configured to discharge fine droplets that are adsorbed on an interface of ultrafine bubbles in the ultrafine bubble-containing water and floated by the stirring, wherein the ultrafine bubble-containing water production device has a storage type pressurized liquid tank configured to swirl the water containing the ultrafine bubbles and the bubbles larger than the ultrafine bubbles in a full state all the time, the storage type pressurized liquid tank is including a central liquid discharge port for discharging a part that contains bubbles larger than the ultrafine bubbles and has a relatively small specific gravity from above by swirling the water in an inside thereof, and a pressurized liquid discharge port provided at a lower side face.
