摘要:
A Sonotrode for generating an ultrasonic field in industrial production processes such as chemical, food, petroleum, pharmaceutical, beverage or mining-related processes for reducing and eliminating foaming of liquid products has a compact one-piece form, wherein the sonotrode is provided with a main body part having a connector for connection with a high frequency generator and having a front face from which the ultrasonic field is directed to the desired spot or area of the product to be de-foamed, wherein the main body part has the shape of a compact block element and in that the front face is concave in shape in relation to a product surface such that the ultrasonic field is focused and directed to a specific area of a product foam to be treated in a concentrated form compared to a non-focused ultrasound.

A sonotrode specially adapted for defoaming liquids during container filing operations, has an upper body portion having a first diameter and having an upper face adapted to be mounted to a driving transducer, a middle body portion having a second diameter larger than the first diameter situated below the upper body portion, a generally conical portion situated between the upper body portion the middle body portion, and a transition portion situated between the middle body portion and a lower face adapted to be directed toward a liquid upper surface within a container, the lower face being generally rectangular.
摘要:
A defoaming method capable of destroying foams generated when a container is filled with drink, or the like, efficiently at a high speed and destroying foams effectively even in the case of a container having a narrow mouth. Liquid surface (6) in a container (1) is irradiated with pulse-like light (2) and a pulse-like sound wave (8) is generated from an irradiated point (7) as a sound source. The pulse-like sound wave thus generated propagates from the sound source as a strong spherical wave to reach a bubble (9) and to destroy the bubble. It can also destroy a bubble located at a place remote from the optical path quickly, thus destroying bubbles efficiently at a high speed. Alternatively, pulse-like light is condensed at a gas portion above the liquid surface and the bubbles can be destroyed with a shock wave generated by breakdown phenomenon.
摘要:
An anti-foaming degassing device for use in fuel dispensing equipment, having: a circulating pump (1) for the fuel, a vortex degassing enclosure (2) connected to the outlet of the pump (1) and provided with a lateral outlet pipe (8) for the degassed fuel and with an axial outlet pipe (9) for a gas-enriched fraction of fuel, a separating vessel (3) connected to the axial outlet pipe (9) in which the liquid fuel is separated by gravity before being transferred back to the pump (1), and control means (20) making it possible to vary the flow rate of the fraction collected by the axial outlet pipe (9) according to its gas content. The axial outlet pipe (9) opens in the lower part of the separating vessel (3), into the gravity-separated liquid fuel, in such a way as to prevent the formation of foam in this vessel.

A member for controlling foam in a material reservoir includes a body, a concave space in the body, and wings extending from the body in the concave space. A method of controlling foam in an ink reservoir of a printing system includes rotating a foam control member above ink in the reservoir to dissipate accumulated foam, where the member includes a concave space open toward the ink and wings extending in the concave space.
摘要:
The present invention includes a horizontal foam fractionation protein skimmer for removing organic waste material (dissolved organic compounds) from organic loaded water. The protein skimmer includes a horizontal reaction chamber connected to a foam collection chamber in which protein-loaded foam containing organic waste material is collected. The reaction chamber is comprised of a series of horizontally-directed, nested, concentric tubes for increasing the number and decreasing the size of bubbles to facilitate efficient removal of dissolved organic compounds. Each horizontal tube has either one or several small openings that are offset from the openings on the adjacent tube at a small angle, typically 10°. The openings are formed by either a single slit that runs along the length of each tube, or by a series of holes that runs along the length of each tube. Organic-loaded water is pumped through tubing into the reaction chamber. As water moves through the tubing, gas (e.g., air) is drawn in by eductors, creating a gas/water mixture. The gas/water mixture is distributed into the horizontal reaction chamber through a lateral manifold that tangentially injects the gas/water mixture at approximately equidistant points along the length of the reaction chamber. The gas/water mixture enters the largest of the nested horizontal tubes and is forced through the small opening(s) into the next smaller diameter tube.Water travels circumferentially through adjacent tubes in a counter-current movement. The most central concentric tube carries the water out of the reaction chamber into the foam collection chamber. The water left behind is considerably more pure and free of contaminates and exits through tubing in the bottom of the foam collection chamber. The horizontal protein skimmer of the present invention is sectioned into individual components that facilitate transport and on-site assembly.
