摘要:
A system and method for processing a fluid, including decontaminating water and generating water vapor includes introducing the fluid into a vessel. The fluid is moved through a series of rotating trays alternately separated by stationary baffles so as to swirl and heat the fluid to effect the vaporization thereof to produce a vapor having at least some of the contaminants separated therefrom. The vapor is removed from the vessel for condensing apart from the separated contaminants and the remaining water. The vapor may be passed through a turbine connected to an electric generator. Sensors in a controller may be employed to adjust the speed of rotation of the trays or fluid input into the vessel in response to the sensed conditions. The treated fluid may be recirculated and reprocessed through the vessel to increase the purification thereof.

The invention relates to a method for carrying out a mass transfer process in a column (1) which comprises at least two separation trays (5), each separation tray (5) having an upper plate (7) and a lower plate (9), with a sluice (13) being formed between the plates (7, 9), and valves (11) that are designed such as to allow gas to flow through the separation tray (5), liquid from the upper plate (7) flowing into the sluice (13) when the gas flow is disrupted, and the liquid running off from the sluice (13) once the gas supply is re-established. The method comprises the following steps: (a) allowing gas issued through the valves (11) in the separation tray (5) to flow through a liquid that is present on the upper plate (7), the amount of gas being sufficiently large to prevent liquid from flowing back through the valve (11); (b) disrupting the gas supply such that the liquid flows into the sluice (13) through the valves (11); (c) continuing the gas supply, the valves (11) in the lower plate (9) being opened such that the liquid runs off from the sluice (13). The sluice (13) is dimensioned such that once the liquid has run off from the top plate (7) into the sluice (13) not more than 70% of the sluice (13) is filled with liquid. The invention also relates to a valve for carrying out said method.

The invention relates to a valve for carrying out a mass transfer process, gas (13) flowing through a liquid (31) that is present on an upper plate (21), the liquid (31) flowing into a sluice (17) below the plate (21) when the gas supply is disrupted and the liquid (31) flowing off from the sluice (17) through a lower plate (19) delimiting the sluice (17) in a downward direction once the gas supply is re-established. The valve (1) comprises a closing element (5) which has a piston rod (5), an upper valve disk (9) and a lower valve disk (7) and is guided in a sleeve (3), the lower valve disk (7), in a first valve position, closing an opening (43) on the lower end of the sleeve (3). The upper valve disk (9) and the lower valve disk (7) are each movably connected to the piston rod (11).

This invention is directed to a cyclonic vapor/liquid contacting device, and distillation or related mass transfer or heat transfer processes employing its use, such as fluid catalytic cracking. Liquid feed is introduced near the floor of the cyclone via the downcomer or plenum. Vapor enters through sieve holes in the bottom of the cyclonic device. Near the floor are angled tabs or vanes that impart a spin to the vapor rising up through the floor. The tabs or vanes mix the liquid and vapor. The liquid is then thrown toward the cyclone wall where it exits through slots in the wall. A second set of tabs or vanes, located about in the middle of the cyclone, imparts additional spin to the vapor and entrained liquid rising through the cyclone. This improves liquid collection by the cyclone, especially in cases where a heavy liquid load dampens the spin action of the vapor in the base of the cyclone. In another embodiment, there is a non-spinning zone at the floor of the cyclone barrel which permits improved heat transfer between the liquid and vapor. If a non-spinning zone is used, the two sets of vanes or tabs are located at higher elevations within the barrel.

Es ist außerdem mindestens eine Zwischenrippe (7) vorhanden, die zwischen jedem Paar der geradlinigen Rippen (6) angeordnet ist. Die Reihe von Umfangslöchem (2) Ist im Anordnungsbereich der geradlinigen und der Zwischenrippen (6,7) ausgeführt.
摘要:
In a centrifugal device for contacting a liquid with a gas or with a second liquid, high rates of mass transfer are achieved by carrying out the contacting on a rotating plate whose surface is capable of creating perturbations in liquid flowing across it.
