Definitions
- the invention therefore aims to overcome the difficulties described above a powerful, self - priming dispersing device for gases and To provide liquids or two-phase turbines, which has a higher mass transfer with the cheapest possible Performance / entry ratios and speed of the dispersing device allowed.
- Dispersing device are therefore several gas channels with the Hollow shaft connected via gas channel openings allow the gas to be dispersed to be discharged.
- the invention By separately guiding the gas to be dispersed within the self-priming disperser the invention is therefore the dispersing device according to the Invention no restrictions by predetermined phase relationships Subject to gas / liquid. So you get according to the invention an extremely powerful and one high self-priming rotating dispersing device or self-priming Two phase turbine.
- the gas channels run approximately radial to the hollow shaft.
- the gas channels under run at an acute angle to the radial which preferably in a range of greater than 0 and less than 25 ° lies and is in particular about 15 °.
- gas channels can be in the form of impellers be trained to pump the fluid thereby intensify.
- each gas channel opening lies in a plane at an acute angle for gas channel wall, which is preferably in one area are from 30 ° to 60 ° and in particular is approximately 50 °. This allows the mass transfer due to the enlarged Improve contact areas even further.
- rotating dispersing device are the gas channels arranged at regular angular intervals in the circumferential direction, in order to be as uniform as possible in the circumferential direction Ensure mixing of gas and liquid.
- the self-priming, rotating dispersing device is a cover plate on the top and bottom of the gas channels provided which is axially to the rotationally driven Hollow shaft are spaced and between them in cooperation chambers are formed with the gas channels.
- the bottom cover plate can be a closed and form surface connected to the hollow shaft.
- the top Cover plate preferably forms a liquid suction gap in cooperation with the outer surface of the hollow shaft. Liquid enters the chambers via this suction gap between the two axially spaced washers and the outer surfaces of the gas channels, the one intensive agitation movement to strengthen the mass transfer is granted.
- the gas channel openings are preferably opposite the direction of rotation of the hollow shaft, so that the intensive mixing of gas and liquid on the area of the gas channels facing away from the flow.
- the underside cover plate 6 forms a closed surface and is firmly connected to the outer wall of the hollow shaft 2 and the corresponding outer surface of the gas channels 3.
- the top cover plate 5 is designed as an annular body and concentrically surrounds the hollow shaft 2 and forms an annular gap 7 between the outer wall of the hollow shaft 2, which serves for liquid suction into the chambers 8 delimited between the two cover plates 5 and 6 and the gas channels 3.
- the cover plates 5 and 6 can be integrally connected to the gas channels 3 accordingly.
- the largest outer diameter of the dispersing device 1 is denoted by D 2 and is measured between the outer edges of two opposite gas channel mouth openings.
- the dispersing device 1 due to the stall at the gas channel openings 4 generates a negative pressure, through which gas from the gas space and the gas channels 3 against the static liquid level is sucked in above the dispersing device 1.
- This sucked in and to be dispersed gas is inside the dispersing device 1 in a line system without Mixing with liquid through the gas channel openings 4 and there is a mixture of gas and liquid to be dispersed outside the Dispersing device 1 in the area around the gas channel openings 4.
- the gas channels 3 cause rotation the hollow shaft 2 intensive liquid delivery and agitation also in cooperation with the chambers 8.
- the gas channels 3 have a curved course and have an impeller-like shape. As a result, the fluid delivery can be further increased.
- the radius of curvature is in a range E 2/3 to 3D 2, preferably at about D 2/2.
- the Gas channels 3 a cross section, which, starting from the Connection to the hollow shaft 2 in the gas flow direction gets bigger. This allows the mass transfer from gas to liquid. Also receives one also further favorable mass transfer ratios, that the gas channel orifices 4 against the Direction of rotation of the hollow shaft 2 are directed.
- Dispersing device 1 are essentially the basic construction elements consistent with the embodiment designed according to Figure 1. These parts are therefore below not explained again, but only the differences compared to the design according to the figure 1. Essentially only the gas channels 3 'have a figure 1 different design.
- Figure 4 shows another embodiment variant in the form a modification to the embodiment of the dispersing device 1 according to Figure 3.
- the gas channels 3 '' ' In deviation from this which communicating in the hollow interior of the hollow shaft 2 Connected gas channels 3 '' 'essentially one constant cross-section over its entire course starting from the hollow shaft 2 to the gas channel opening 4.Otherwise, the gas channels 3 '' ' also essentially radial to the hollow shaft 2 and each have an opening cross section in the area of Gas channel opening 4 in a plane below one acute angle ⁇ to the gas duct wall.
