摘要:
The specification discloses a gas dispersion pipe in which a gas is introduced via an upper and thereinto, which is ejected via a lower end into a liquid to carry out a gas-liquid contact operation, and gas-liquid contact method and apparatus using this pipe. The gas dispersion pipe is formed so that an upper end portion thereof has a convergent pipe structure having a downwardly decreasing horizontal cross-sectional area, and/or so that a lower end portion has a nozzle structure having a downwardly decreasing horizontal cross-sectional area. This gas dispersion pipe may be provided therein with a gas guide member, the horizontal cross-sectional area of which increases downward, instead of forming the lower end portion thereof to a nozzle structure.

A gas/fluid mass exchange apparatus is disclosed. The apparatus comprises a gas permeable membrane which is arranged to separate a first region for receiving a gas flow, from a second region for receiving a fluid flow. The apparatus further comprises support means which is arranged to maintain the shape and orientation of the membrane.

A sparger 34 includes a body 62 bounding a compartment. A tubular port or tube 66 is coupled with the body. The tubular port or tube bounds a passage 76 that communicates with the compartment of the body. At least a portion of the body includes of a first sparging sheet 64. The first sparing sheet includes a flexible sheet of a gas permeable material such that a gas passing into the compartment of the body through the passage can exit the compartment by permeating through the first sparging sheet.

A gas dispersion pipe into which gas is introduced through its top end portion and blown out from its bottom end portion into liquid for gas-liquid contact, and a method and a device for gas-liquid contact employing the gas dispersion pipe are disclosed. The gas dispersion pipe has its top end portion formed in a contraction pipe with its horizontal cross-sectional area decreasing downward and/or its bottom end portion formed in a nozzle structure with its horizontal cross-sectional area decreasing downward. In stead of making the gas dispersion pipe with its bottom end portion in the nozzle structure, a gas guide member with its horizontal cross-sectional area increasing downward may be disposed within the bottom end portion of the gas dispersion pipe.

A hybrid contact tray for a mass transfer column is provided. The tray has a deck for passage of liquid along a liquid flow path thereon. The deck also has a plurality of orifices for passage of ascending vapor through the tray deck. The contact tray includes a cross-current vapor-liquid mixing section having a first portion of the plurality of orifices and a co-current vapor-liquid mixing section comprising at least one co-current mixing device associated with a second portion of the plurality of orifices. The co-current mixing device includes a conduit having: a vapor inlet in fluid communication with one or more of the second portion of orifices; a froth inlet in fluid communication with the liquid flow path; a fluid outlet; and a packing material within a co-current flow path of vapor and liquid within the conduit disposed after the vapor and froth inlets and before the fluid outlet.

A selective hydrogen adding equipment is provided by which living organism applicable hydrogen-contained fluid is obtained without changing properties of the living organism applicable fluid. Living organism applicable hydrogen-contained fluid is obtained through storing a hydrogen generating system, which contains a hydrogen generating agent as an essential component, in a hydrogen bubble forming implement which has a gas/liquid separating section including a gas-permeable film or an open-close type valve, causing the hydrogen generating system and a generating-purpose water to react in the hydrogen bubble forming implement, and supplying hydrogen gas generated in the hydrogen bubble forming implement into living organism applicable fluid via the gas/liquid separating section.

A gas-liquid mixing vessel (2) utilizes an axial flow, down-pumping impeller (8) in a draft tube (1) to create vortex development so as to draw gas from the overhead in a body of recirculating liquid (3). A surge tank (13) is used to accommodate volume changes in the vessel (2), and a liquid level control feature, in which the gas phase pressures in the mixing vessel (2) and the surge tank (13) are adjusted, is used to maintain the liquid level (4) in the mixing vessel (2) at a desired level for proper vortex development.
