Abstract:
The invention is directed to an arrangement of two conduits (2a, 2b), wherein the conduits are positioned parallel with respect to each other and wherein each conduit is provided with means suitable to remove solids from its surface and positioned along the length of one of the two sides of the conduit (2b), wherein the means are one or more pairs of oppositely oriented nozzles (3a, 3b), each nozzle (3a) having an outflow opening (4b) for gas directed, along the surface of the conduit (2a, 2b), towards the outflow opening (5) of the other nozzle (3b) of said pair (3a, 3b), wherein the pairs of oppositely oriented nozzles of one conduit (2a) are arranged in a staggered configuration relative to the pairs of oppositely oriented nozzles (6, 6a) of the other conduit (2a).
Abstract:
The present invention relates to an apparatus for the treatment of contaminated air or surfaces in order to remove or oxidize odoriferous gases and deleterious compounds therefrom through the utilization of ozone droplets, and more particularly pertains to the treatment of manufacturing facilities, wet wells, seage installations, buldings, equipment and industrial installations and diverse locales subjected to foul air, in order to remove noxious and potentially toxic vapors and impurities from the air or surfaces through the dissolution of ozone in water to form droplets, and spraying the resultant mixture into the air as a fine aqueous mist. Moreover, the invention is also directed to the provision of a process for eliminiating odoriferous or noxious vapor gases and harmful constituents entrained therein from a volume of contaminated air or surfaces through the utilization of ozone dissolved in water by the employment of the inventive treatment apparatus.
Abstract:
A nozzle for producing a liquid jet or a single-file stream of droplets of a fluid, methods using the nozzle, and an injector comprising the nozzle of the invention for providing the liquid jet or single-file stream of a fluid to a vacuum system are described.
Abstract:
The invention relates to a spray mixer for mixing and spraying at least two flowable components. The spray mixer (22) is provided with a tubular outer mixer housing (23) which extends in the direction of a mixer longitudinal axis (24) from a mixer start (25) to a distal mixer end (26). A mixer inner housing (29) which accommodates a mixer element (33) is arranged in the mixer outer housing (23). A mixer compressed air inlet (31) is arranged at the mixer start (25). The mixer compressed air inlet (31) is connected by means of a mixer compressed air channel (30) to an annular mixer compressed air outlet (32) which encloses a mixer outlet opening (35). In the operation of the spray mixer (22), compressed air is supplied via the mixer compressed air inlet (31), flows through the mixer compressed air channel (30) to the mixer compressed air outlet (32) and atomises and sprays the material emerging from the mixer outlet opening (35). In order for the spray mixer to be easy to handle, the mixer outer housing (23), the mixer inner housing (29) and the mixer element (33) are combined in a single unit. This is achieved by connecting the indicated components to each other in a manner to secure against loss.
Abstract:
The invention relates to a method and device for obtaining micro and nanometric particles in a controlled, reproducible manner. The aforementioned particles have a spherical shape and a very narrow, uniform size distribution. More specifically, the invention relates to a novel method of forming emulsions and to the application thereof in micro and nanoencapsulation techniques involving the extraction/evaporation of the solvent. In particular, the invention relates to the encapsulation of the fluorescent compounds and the subsequent application thereof.
Abstract:
The invention relates to a plasma transfer wire arc thermal spray system, comprising a section for feeding a wire (20) acting as a first electrode, a source of plasma gas providing plasma gas (16), a nozzle (10) directing the plasma gas stream (16) from the source of plasma gas to a free end (21 ) of the wire (20), and a second electrode (30) located in the plasma gas stream (16) towards the nozzle. The inventions is characterized in that the nozzle (10) is made at least partially of electrically insulating material. The thermal spray apparatus with the inventive spray gun is having a simplified and faster starting procedure and is the spray nozzle is more durable.
Abstract:
A blowing device for compressed air or the like comprising at least one supply channel (15) which is connectable to a source of compressed air and the outlet(s) (19) of which is, (are) shaped to impart to the compressed air a jet in the form of a ring or part of a ring, and further comprising at least one communication channel (20) adapted to connect the inside of the jet (C) with the atmosphere. The object of the invention is to provide a blow nozzle with a large contact surface between outflowing pressurized air and the ambient air in order to provide an airflow with a low sound level, a large momentum, high efficiency and reduce striking velocity against the object intended to be cooled, dried or blown clean. This has been attained in that the product of, on the one hand, the ratio between the outer plus the inner circumference (O2 and O1) of the outlet (19) and its area (Aout) and, on the other hand the inner diameter (D) of the outlet and its width (S), is at least 4 mm/mm , preferably considerably larger than 4 mm/mm .
Abstract:
An impingement injector includes an injector core having a plurality of conduits. The conduits include a first conduit and second conduits disposed circumferentially around the first conduit. The second conduits are at an impinging angle with respect to the first conduit. Replaceable, tunable jets are disposed in corresponding ones of the second conduits.
