摘要： An ejector includes a first nozzle, a second nozzle, an atomization mechanism, and a mixer. A working fluid in a liquid phase is supplied to the first nozzle as a drive flow. A working fluid in a gas phase is sucked into the second nozzle. The atomization mechanism is disposed at an end of the first nozzle and atomizes the working fluid in a liquid phase while maintaining the liquid phase. The mixer generates a fluid mixture by mixing the atomized working fluid generated by the atomization mechanism and the working fluid in a gas phase sucked into the second nozzle.

摘要： A fluid mover (1) includes a hollow body (2) provided with a straight-through passage (3) of substantially constant cross section with an inlet end (4) an outlet end (5) for the entry and discharge respectively of a working fluid. A nozzle (16) substantially circumscribes and opens into the passage (3) intermediate the inlet (4) and outlet (5) ends. An inlet (10) communicates with the nozzle (16) for the introduction of a transport fluid and a mixing chamber (3A) is formed within the passage (3) downstream of the nozzle (16). The nozzle internal geometry and the bore profile immediately upstream of the nozzle exit are disposed and configured to optimise the energy transfer between the transport fluid and working fluid. In use, through the introduction of transport fluid, the working fluid or fluids are atomised to form a dispersed vapour/droplet flow regime with locally supersonic flow conditions within a pseudo-vena contracta, resulting in the creation of a supersonic condensation shock wave (17) within the downstream mixing chamber (3A) by the condensation of the transport fluid. Methods of moving and processing fluids using the fluid mover are also disclosed.

摘要： A multi-stage ejector pump has an ejector nozzle system (18) whose nozzles are situated coaxially behind each other and are axially set apart from each other (compressed gaz nozzle (18A) and diffusors (18B, 18C)). Said ejector nozzle system can be axially sealingly pushed into a nozzle-receiving shaft (14) of a housing element (12). The housing wall is interrupted in the area of the suction gas inlet gap (24A, 24B) between adjacent nozzles to provide a fluid connection to suction chambers. The aim of the invention is to provide a multi-stage ejector pump of this type which has a compact construction, interchangeable nozzles and a high degree of efficiency. To this end, the ejector nozzle systems (18) are made up of a set of individual nozzles and nozzle spacers (22A, 22B) and each of the individual nozzles is provided with support elements on its outer periphery. Said support elements are axially set apart and provide tilt-free or low-tilt support in relation to the wall of the nozzle-receiving shaft (14). The nozzles and the nozzle spacers are held in contact with each other.

摘要： An fluid handling device (10) having an elongate tubular body which defines a through bore (20) between an inlet end (13) and an outlet end (14) of the body. The device also includes first and second annular chambers (30,38), each of which extends substantially concentrically around the bore (20), the first chamber (30) being in communication with the bore (20) via a first set of passages (48) spaced circumferentially around the bore (20), and the second chamber (38) being in communication with the bore (20) via a second set of passages (49) spaced circumferentially around the bore (20). The passages (48,49) of each set communicate with the bore (20) at a respective axial location (45,46) intermediate the ends (13,14) of the bore (20), with the location (46) for the second set (49) being between the location (45) for the first set (48) and the outlet end (14) of the housing, and each passage of each set (48,49) having an opening into the bore (20) which faces towards the outlet end (14) of the body. The device (10) also includes a first inlet port (42) by which the first chamber (30) is connectable to a source of pressurised fluid, and a second inlet port (44) by which the second chamber (38) is connectable to a source of pressurised fluid. The passages (48,49) of each set are inclined radially towards the axis A of the bore (20) along respective lines such that the lines for passages of the first set (48) converge along the bore (20) to a first region X towards, at or beyond the outlet end (14), and the lines for passages of the second set (49) converge to a second region Y beyond the first region X.

摘要： This invention relates to an ejector apparatus of a fluidized bed heat-treating furnace for performing heat-treatment of a work A put into a fluidized bed (2) by circulating an exhaust gas at the upper layer portion of a retort (1) driven by a compressed gas and enclosing therein the fluidized bed (2) from the bottom of the retort (1) to its inside so as to cause fluidization of the fluidized bed (2). The main body (5a) of an ejector (5) consists of at least three members (7, 8, 9), and at least two systems of compressed gases are supplied to contracting portions (8d, 9d) from compressed gas inlets (12, 15) defined between the ejector members (7, 8, 9) through gaps formed between the ejector members (7, 8, 9). The gap of each ejector member (7, 8, 9) can be adjusted suitably by adjusting means (F, G). Therefore, the absorption efficiency of the ejector (5) can be freely adjusted over a wide range. Since a center rod of a prior art apparatus does not exist, the ejector (5) has a simple structure as a whole and is moreover compact.
