Abstract:
Condensing apparatuses and their use in various heat and mass exchange systems are generally described. The condensing apparatuses, such as bubble column condensers, may employ a heat exchanger positioned external to the condensing vessel to remove heat from a bubble column condenser outlet stream to produce a heat exchanger outlet stream. In certain cases, the condensing apparatus may also include a cooling device positioned external to the vessel configured and positioned to remove heat from the heat exchanger outlet stream to produce a cooling device outlet stream. The condensing apparatus may be configured to include various internal features, such as a vapor distribution region and/or a plurality of liquid flow control weirs and/or chambers within the apparatus having an aspect ratio of at least 1.5. A condensing apparatus may be coupled with a humidifier to form part of a desalination system, in certain cases.
Abstract:
A refrigerator is disclosed. The refrigerator includes a body, a carbonated water tank to produce carbonated water through mixing of clean water with carbon dioxide gas, a sensor unit inserted, at at least a portion thereof, into the carbonated water tank, to sense an internal state of the carbonated water tank, and a holding unit disposed at one side of the carbonated water tank while holding the sensor unit in a fixed state. Through this configuration, it is possible to achieve easy coupling of the sensor unit and lines to the carbonated water tank while preventing water leakage even when the internal pressure of the carbonated water tank is high.
Abstract:
The prior arts generate bubbles with fixed characteristics of the gas in the bubbles. The invention proposes an apparatus of generating bubbles and a method thereof. The apparatus comprising: a first unit (10) configured to determine at least one characteristic of a gas in the bubbles; a second unit (12) configured to generate the bubbles, comprising: an electrolyzer (120) configured to electrolyze an electrolyte to generate the gas in the electrolyte, thereby generating bubbles; and a controller (14), configured to control the second unit to generate the bubbles according to the at least one characteristic of the gas. In embodiments of the invention, the generation is controllable with respect to the gas in the bubble based on the practical requirement of the gas, and is more flexible and with wide applicability.
Abstract:
Disclosed is a micro bubble generation device. The micro bubble generation device comprises: a rotating unit which receives a mixture of water and gas that flow thereinto, enables the water and the gas to be rotated by colliding with each other, and discharges the dissolved water; a dissolution tank which stores the dissolved water that is discharged from the rotating unit; and a nozzle unit which receives the dissolved water that flows thereinto, and generates micro bubbles in the water. Thus, micro bubbles having the dimension of 100nm or less can be generated in large quantities by using low power.
Abstract:
Begasungsvorrichtung für Bioreaktoren mit einem in einem Gehäuse angeordneten Begasungselement mit Gasaustrittsöffnungen, wobei das Begasungselement als einMikrosparger ausgebildet ist, dessen Gasaustrittsöffnungen jeweils beabstandet zueinander angeordnet sind und eine Größe zwischen 100 μm und 200 μm aufweisen. Bevorzugt ist mindestens ein zweites Begasungselement mit Gasaustrittsöffnungen einer zweiten Größe vorgesehen ist, wobei die Begasungselemente von einem gemeinsamen Gehäuse mit getrennten Begasungskanälen gebildet werden.
Abstract:
Biomass feedstocks (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful products, such as fuels. For example, systems are described that can convert feedstock materials to a sugar solution, which can then be fermented to produce ethanol. Biomass feedstock is saccharified in a vessel by operation of a jet mixer, the vessel also containing a fluid medium and a saccharifying agent.
Abstract:
A system (10) for dissolving gas into liquid contained within a body, the system comprising a tubular body (20) extending between a bottom end (26) and a top end (24), a gas diffuser (42) coupleable to a gas source (38) and configured for discharging gas bubbles into the tubular body, and a liquid pump (30) for propelling liquid within the tubular body in a downwards direction, against uprising gas bubbles, where the liquid egresses at the bottom end of the tubular body.
Abstract:
A sonic saturation system is provided that comprises at least one tank for containing a reservoir of liquid solvent; at least one gas-inlet in fluid communication with a gas compressor, for introducing gaseous solute into the reservoir, and at least one sonic agitator for agitating the liquid reservoir thereby increasing the rate of impregnation of the solute into the solvent.
Abstract:
The invention relates to a device which can be used to aerate a body of liquid such as wine. The device is provided to be portable and to be used with a body of liquid which is held within a container from which the liquid can be directly consumed.
