Disclosed is a wind-driven rotating and shaking breather, comprising an open container having a circular cross section, and a lid covering an opening of the open container and having a wind wheel and a motor. A rotating shaft of the motor is connected to the wind wheel. The wind wheel is mounted on a lower portion of the lid and composed of an impeller and a flat bottom plate disposed below the impeller. The wind wheel, horizontally arranged, is inserted into the open container and located above red wine contained in the open container. An edge of the lid or a side wall of the container is provided with an air outlet. The motor drives the wind wheel to extract air in the open container and discharge the air from the air outlet. By using the breather, the purpose of fast breathing is achieved. Also disclosed is a breathing method.

A microbubble generator and a laundry treating device. The microbubble generator includes: an air dissolving tank, having an air dissolving cavity defined therein, and an inlet and an outlet configured to feed and discharge water, the inlet being located above the outlet, the inlet and the outlet being staggered in a horizontal direction; and a cavitator, provided outside the air dissolving tank and connected with the outlet, or provided at the outlet.

A microbubble generator and a laundry treating device. The microbubble generator includes: an air dissolving tank, having an air dissolving cavity defined therein, and an inlet and an outlet configured to allow water to flow in and out, the inlet being located above the outlet; a baffle, provided in the air dissolving tank, at least partially located between the inlet and the outlet in a horizontal direction, and provided with a gap and/or a through hole; and a cavitator, provided outside the air dissolving tank and connected with the outlet, or provided at the outlet.

A reactor for gas-liquid mass transfer between a gas and a liquid or slurry includes a tank for receiving the liquid or slurry having a wall; a drive shaft; an upward pumping impeller; and an aerating apparatus disposed above the upward pumping impeller and extending between the drive shaft and the wall of the tank at a first distance (d1) from the drive shaft and at a second distance (d2) from the wall of the tank, the aerating apparatus encircling the drive shaft at least partially. The aerating apparatus has an outward inclined or curved inner surface for directing at least a part of the flow over the inner surface.

An aerator for aerating a liquid as the liquid is being poured from a container includes an aerator body configured to be at least partially inserted into the container. The body includes an inlet, an outlet, and a flow control chamber disposed between the inlet and the outlet. A flow control element is movably disposed in the flow control chamber between a first position where the flow control element is spaced away from a stop and a second position where the flow control element engages the stop. The flow control chamber communicates with the outlet when the flow control element is in the second position allowing liquid to be poured from the container and allowing air to be introduced into the flow control chamber for mixing with the liquid being poured from the container to aerate the liquid being poured from the container.

A configuration for water purification undergoes the water supply step of taking in treatment water through a water suction port and pressure-feeding the treatment water, the air supply step of taking in air through an air suction port and supplying the air, the oxygen amount increasing step of pressurizing the air supplied at the air supply step to increase the total amount of oxygen, the ionization step of ionizing the pressurized air subjected to the oxygen amount increasing step, the mixing step of obtaining gas-liquid mixing fluid subjected to first fine air bubble formation by spraying the air into the flow of treatment water, and the accelerated spraying step of performing second fine air bubble formation by accelerating a flow velocity by a narrowed-diameter portion provided at a spray nozzle when the gas-liquid mixing fluid obtained through the mixing step is sprayed into the treatment water.

The present disclosure relates to a valve tray for use in a chemical process column. The valve tray includes a plurality of apertures formed therein. A plurality of valves are maintained in a spaced relationship relative to individual apertures of the plurality of apertures. An area of the individual apertures is less than an area of individual valves of the plurality of valves.

A washing machine capable of generating bubbles from a water/air mixture and supplying bubbles to the tub to facilitate removal of residual detergent or the like from laundry during washing or rinsing operations. The washing machine has a dissolving unit with an air supply check valve and can receive air from outside of the dissolving unit in accordance with a pressure in the dissolving unit. Air contained in the dissolving unit can be dissolved in water contained therein to produce water/air mixture. A bubble generating unit receives the water/air mixture from the dissolving unit and generates bubbles as the mixture passes along a water flow path and a pressure reduction region in the bubble generating unit.
