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 1):
An ultrafine bubble cleaning method for cleaning a substance to be cleaned, comprising: swirling a liquid in a storage type pressurized liquid tank in a full state all the time, the liquid is 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 from the storage type pressurized liquid tank, storing the ultrafine bubble-containing liquid containing the ultrafine bubbles concentrated outside in a reservoir, stirring the ultrafine bubble-containing liquid in a state in which the substance to be cleaned, is contained, washing off fine particles adhered to the substance to be cleaned while causing the fine particles to be adsorbed on an interface of the ultrafine bubbles, causing the fine particles to be floated as a floated and separated substance, and causing the substance to be cleaned in which the fine particles are rinsed off to be settled as sedimentation isolates; and discharging a supernatant containing the floated and separated substance.
