Abstract:
Apparatus and method for increasing dissolved oxygen levels in a liquid. An oxygenation system (100) includes a liquid source (102) from which liquid is introduced into a piping network (106) by a pump (104). Colloidal minerals are injected into the liquid in a dwell chamber (110). The mixture of liquid and minerals flows into an oxygenator (118) where gaseous oxygen is injected into the liquid. The resulting two-phase flow stream is accelerated to supersonic speeds through a linear flow accelerator (126) comprising a flat Venturi (130) and electromagnets (128) positioned adjacent the flat Venturi. The electromagnets generate an electromagnetic field to exert a force on the two-phase mixture in the direction of the flow. The flow stream then passes through a laminar flow grid (132) to remove turbulence, after which the oxygenated liquid is bottled at a bottling system (134).

The device is used in power engineering, ship-building, and machine-building industries as well as in transport for preparation of high-quality water-fuel emulsions. Objective of the invention is to reduce power consumption. The device for preparation of a water-fuel emulsion comprises a blending chamber 3, as well as a fuel nozzle 4 and a water nozzle 5 for supply of respective mediums in the chamber 3. A nozzle that ensures boiling of water is used as the water nozzle 5. The water nozzle 5 comprises inlet 6 and outlet 7 sections that are respectively convergent and divergent in the direction of the medium flow, between which the minimal cross-section S min of the nozzle is located. The generatrix of a fore part of the divergent section 7 of the nozzle 5 has a concave shape of the curve in relation to the axis of the nozzle 5, which curve goes smoothly into a convex curve in relation to the axis of the nozzle 5 in the critical cross-section S cr of the nozzle 5. The water nozzle 5 is located on a longitudinal axis 2 of the chamber 3 while the fuel nozzle 4 is located in line with the water nozzle 5 and is shaped as a ring enveloping an end part of the water nozzle 5.

Abstract:
The present invention pertains to the field of jet-generation techniques. A gas-liquid mixture is fed from a jet apparatus into a jet converter where the flow of said gas-liquid mixture is first converted by its expansion into a supersonic liquid-gas flow. This supersonic liquid-gas flow is then slowed down in a profiled flow section of the converter for generating a pressure jump and for partially converting the kinetic energy of the flow into pressure energy. In order to implement this operation process, the apparatus includes a jet converter for the flow which comprises an expansion chamber as well as a profiled flow section. The inlet of the expansion chamber is connected to the outlet of the jet apparatus while the outlet of the profiled flow section is connected to a separator.
Abstract:
Appareil et procédé d'émulsification de fluides. Le mélange de fluides peut se faire soit avant que les fluides n'entrent dans l'appareil (100), soit dans l'appareil. Une pression extrêmement basse est créée et maintenue dans une chambre de l'appareil en augmentant la vitesse de l'écoulement d'au moins un fluide en faisant passer l'écoulement d'un passage de plus grand diamètre (110) vers un passage de plus petit diamètre (106). Des vapeurs des fluides à émulsifier se mélangent dans le passage de basse pression, lequel peut être un tube venturi. Lorsque les vapeurs mélangées passent du passage de plus petit diamètre vers un second passage de sortie de plus grand diamètre (114), la décélération se traduit par une augmentation de pression qui provoque l'affaissement des vapeurs mélangées dans les produits émulsifiés. Une seule émulsification dans l'appareil produit des particules émulsifiées ayant des diamètres de l'ordre de 0,01 à 2 microns. L'appareil peut effectuer l'homogénéisation du lait, l'émulsification d'un combustible et de l'eau, l'émulsification de solutions avec des fluides immiscibles et la production d'autres émulsions régulières ou thixotropiques.
Abstract:
An apparatus and process for oxygenating a liquid. The apparatus includes a liquid pump fluidly connected to an injector (74) having a liquid inlet (72) forming a nozzle, a liquid outlet (94) and an oxygen inlet (96) therebetween, the injector arranged such that the injector liquid inlet (72) is above the injector liquid outlet (94), and a downwardly opening first diffuser portion (100) connected to the injector outlet (94). The first diffuser portion (100) is serially connected to a second diffuser portion (102) located below the first diffuser portion. Liquid being pumped by the pump is conducted downwardly through the injector (74) and the first diffuser portion (100) to the second diffuser portion (102). The process includes the steps of first, introducing a liquid under pressure into the injector and flowing it liquid downwardly through the injector at a selected liquid volume flow rate; second, introducing oxygen into the injector to create an admixture of liquid and large oxygen bubbles, third, introducing the mixture of liquid and large oxygen bubbles from the injector into the first diffuser portion at such velocity to create the shockwave in the first diffuser portion; fourth, breaking up the large oxygen bubbles into a greater number of small oxygen bubbles; fifth, introducing a mixture of liquid and small oxygen bubbles from the first diffuser portion into the second diffuser portion, which may be a continuation of the first diffuser portion and wherein the presure of the admixture is increased; sixth, floating some of the bubbles upwards against the downward liquid flow and breaking them down to smaller size; continuing the fourth through sixth steps until the smaller bubbles no longer float upwards; and recovering the oxygen-enriched liquid.
