A device for adding and mixing an additive into a hydraulically settable mixture includes a tubular cavity for conducting the hydraulically settable mixture through in an intended flow direction, wherein a static flow-influencing element, in which there is an aperture that leads into the cavity and is intended for introducing the additive, projects into the cavity.

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.

An automated drilling-fluid additive system and method for on-site real-time analysis and additive treatment of drilling fluid to be injected into a well. The drilling fluid includes returned drilling fluid intended to be re-used, which has a variety of viscosity and other qualities resulting from its various preceding use. The target drilling fluid will have a variety of viscosity and other qualities depending upon and changing with various phases of drilling operations and various conditions encountered. The drilling fluid is analyzed in real time as it flows into the automated drilling-fluid additive system, and various additives are added to and thoroughly blended with the drilling fluid as needed to achieve the desired result. The blended drilling fluid is discharged from the automated drilling-fluid additive system in the proper condition for injection into a well.

An impeller-free vortex generator apparatus for fluid mixing, including: a fluid tank including: a first fluid inlet port, the first fluid inlet port including a curved flow channel between a first sidewall segment of the fluid tank and a second sidewall segment of the fluid tank, a second fluid inlet port, and a fluid outlet port; and a first fluid intake duct in fluid communication with the first fluid inlet port; wherein the first fluid intake duct is provided substantially on a tangent to the first sidewall segment of the fluid tank and aligned to deliver a first fluid to an internal surface of the first sidewall segment.

A system includes a high-pressure static mixer. The system also includes a clean fluid system that provides clean fluid to the first high-pressure static mixer at a first fluid velocity and a proppant fluid system that provides a proppant concentrate to the first high-pressure static mixer at a second fluid velocity. Additionally, the system includes a wellhead in fluid communication with the first high-pressure static mixer. The wellhead receives a mixed fluid including the clean fluid and the proppant concentrate from the first high-pressure static mixer.

A method for manufacturing beverage or other liquid containing bubbles uses a system for manufacturing bubble-containing liquid that includes: a bubble generating unit that generates fine bubbles in a liquid; a bubble collapsing unit that is connected to the bubble generating unit to collapse the fine bubbles contained in the bubble-containing liquid supplied from the bubble generating unit by making the bubble-containing liquid pass through the bubble collapsing unit and irradiating the bubble-containing liquid with ultrasonic wave; and a storage unit that is connected to the bubble collapsing unit to store the bubble-containing liquid supplied from the bubble collapsing unit. The method includes: a bubble generating step of generating the fine bubbles in the liquid by the bubble generating unit; a bubble collapsing step of generating superfine bubbles by forming an ultrasonic field by the bubble collapsing unit to collapse the fine bubbles contained in the liquid; and a storage step of storing the bubble-containing liquid containing the superfine bubbles by the storage unit. Consequently, beverage or other liquid containing the superfine bubbles can be manufactured.

An automated drilling-fluid additive system and method for on-site real-time analysis and additive treatment of drilling fluid to be directly injected into a well without additional storage or handling. The drilling fluid includes returned drilling fluid intended to be re-used, which has a variety of viscosity and other qualities resulting from its various preceding use. The target drilling fluid will have a variety of viscosity and other qualities depending upon and changing with various phases of drilling operations and various conditions encountered. The drilling fluid is analyzed in real time as it flows into the automated drilling-fluid additive system, and various additives are added to and thoroughly blended with the drilling fluid as needed to achieve the desired result. The blended drilling fluid is collimated to produce a laminar flow and is discharged from the automated drilling-fluid additive system in the proper condition for direct injection into a well without any storage in a holding tank and without any further processing, treatment, or handling.
