Definitions
- the invention relates to a cyclone for the separation of solid particles and/or at least one liquid from a fluid.
- the cyclone comprises a housing, an inlet opening for introducing the fluid together with the solid particles and/or the at least one liquid into the housing, a discharge port for the solid particles and/or the at least one liquid, a housing cap which is arranged opposite to the discharge port, a dip tube (immersion tube) being provided in the housing cap (cover) for discharging fluid from the housing and a feed channel which opens out into the inlet opening in the housing for introducing the fluid together with the solid particles and/or the at least one liquid into the housing.
- the fluid is a gas stream or, in the case of hydrocyclones, a liquid stream.
- CFB combustion circular fluid bed combustion
- ESP electrical precipi- tator
- gas cyclones are used for filtering out particulate solids from the hot flue gas or from the product gas mixture.
- cyclones are also used in steam power plants for separating water from live steam be- tween the steam generator and the turbine or for condensate separation in gas coolers.
- hydrocyclones solid particles which are contained in suspensions can be separated or classified.
- emulsions such as for example oil-water mixtures are resolved.
- the mode of operation of these centrifugal separators is the same.
- the fluid together with the solids or liquids contained therein is fed from the fluid source via the feed channel into the housing of the cyclone.
- the main portion of the volume stream of the fluid (about 90 %) is forced as a main stream onto a helical path, so that due to the centrifugal force the particles to be separated are thrown towards the wall of the housing. This results in the fact that the particles are separated from the stream and fall or flow downwards into the direction of the discharge port.
- the fluid being purified by removal of the particles exits the cyclone, for example, through a vortex finder in the form of a dip tube.
- a low energy zone is formed in which no efficient separation of the particles takes place. Therefore, the particles are accumulated in this region and, in addition, due to the low pressure in the region of the inner vortex they can be drawn into the direction of the dip tube. Therefore, these particles exit the cyclone through the gas outlet and not, as desired, through the discharge port. Thus, the separation efficiency of the cyclone is considerably compromised.
- the feed channel is characterized by a relatively high length. While the fluid flows through such a long feed channel, through the influence of gravitation the particles travel into the direction of the lower wall of the feed channel. So the accumulation of particles in the low energy zone near the housing cap is reduced. But due to their size (length) such feed channels have a very high weight, take up much space and are extremely expensive.
- the design of the feed channel is shorter and smaller for saving space and costs. But, since the residence time of the fluid in the feed channel is considerably shorter, the particles are not allowed to sufficiently move into the direction of the lower wall of the feed channel. Therefore, the particles are also introduced into the housing of the cyclone directly at the housing cap, and so it is possible that they are accumulated in the low ener- gy zone and compromise the separation efficiency.
- a modification of the feed channel is known from US 6,322,601 B1 .
- An inclined protrusion is provided at the upper wall of the feed channel and extends along the whole length (5 m) and the whole width of the feed channel.
- the slope of the protrusion is ⁇ 20 %, wherein its height from the inner wall to the outer wall of the feed channel decreases.
- Document DE 26 47 486 A1 discloses a hydrocyclones in which the feed channel starts external from the sorting tube and continues in spiral form into the interior of the hydrocyclone.
- the gas stream introduced through the feed channel is thus guided in the upper annular space tangentially towards the dip tube. This, however, creates the problem that the particles/liquid are guided to the dip tube, accumulate in the boundary layer and may leave the cyclone without separation from the gas stream following the wall of the immersion tube.
- the cyclone is equipped with a feed channel which opens out into the inlet opening in the housing and which may connect the inlet opening with the source of the fluid, such as for example with a blast furnace, fluidized-bed furnace or the like.
- the cyclone comprises at least one ramp which is arranged at the housing cap and/or at an upper wall of the feed channel, wherein the slope of the at least one ramp is in a range of 15° to 60°, preferably between 25° and 45°, particularly preferably between 20° and 40° and in particularly about 30°.
- the relative directions 'upper' and 'lower' are defined by the orientation of the cyclone housing.
- "Upper” is the side of the cyclone at which the housing cap can be found, while Jower” is defined by the position of the discharge port.
- Jower is defined by the position of the discharge port. In the case of a typical orientation of the cyclone, thus, the downward direction (top down) is identical with the direction of gravitation, because so the particles fall into the direction of the discharge port.
- the shape of the at least one ramp is not restricted, and therefore it may comprise for example steps, rims and/or corrugations.
- the ramp may be characterized by a continuously rising height, with or without regions of constant height.
- the slope of the ramp results from the quotient of the maximum height and the length of the ramp. Due to the slope of the ramp according to the present invention the fluid together with the particles is deflected in an efficient manner.
- the ramp in particular, directs the particles into a zone of the cyclone in which the distance from the ceiling is higher than the half of the height of the inlet opening. In this zone the particles can efficiently be separated from the fluid.
- the particles With the ramp according to the present invention at the upper wall of the feed channel the particles are deflected in downward direction, that is into the direction of a lower wall of the feed channel. Therefore, they reach the housing of the cyclone already with a higher distance from the housing cap and with a velocity vector having a component in downward direction. So, in particular, in the sec- ondary stream the contained particles are depleted so that they in great part do not reach the low energy zone near the housing cap.
- the ramp ends before reaching the immersion tube. This ensures that the loaded gas stream separates from the wall and is fully exposed to the separation effect of the cyclone.
- the separation efficiency of the cyclone can be improved significantly. As no turbulences are created, the pressure loss in the cyclone is not influenced.
- the feed channel is tangentially arranged at the housing and the ramp at the upper wall of the feed channel rests against the inner wall of the feed channel. By the tangential arrangement of the feed channel an inner wall and an outer wall of the feed channel are defined.
- the inner wall is that side which has a smaller tangential distance to the center of the cyclone housing.
- the right wall (with respect to the direction of the fluid stream in the feed channel) is the inner wall of the feed channel.
- the left wall of the feed channel is the inner wall.
- the wall which is arranged opposite each is the outer wall of the feed channel.
- the length of the at least one ramp at the upper wall of the feed channel is shorter than the length of the feed channel, preferably between 5 and 80 % of the length of the feed channel, particularly preferably between 20 and 50 % of the length of the feed channel, and in particular the ramp extends along about 20 %, 30 %, 40 % or 50 % of the length of the feed channel.
- the uniform cross-section of the feed channel before the start of the ramp results in synchronizing of the fluid flow in the feed channel and reducing of turbulences so that the flow guidance can be controlled by the ramp and can be achieved with better efficiency and less particles reach the low energy zone.
- the ramp at the upper wall of the feed channel extends up to the inlet opening of the housing. According to that the ramp starts in the feed channel and ends for example at the posi- tion of the inlet opening. Accordingly, the ramp is not positioned in the center, but at the end of the feed channel. So the particles are deflected downwards directly before the inlet opening of the housing, which results in a particularly effective prevention of an accumulation of particles in the low energy zone.
- the at least one ramp may have a design of a wedge. The arrangement of the ramp is chosen such that the ramp in the direction of the inlet opening of the housing becomes higher. A ramp having the shape of a wedge has a particularly simple design and, therefore, can be produced very cost-effective.
- the at least one ramp may have a concave design, wherein the slope of the ramp in the direction of the inlet opening of the housing increases.
- the radius of curvature of the ramp can be varied. With this additional parameter the flow of the fluid can be optimized in a particularly effective manner.
- the at least one ramp has a maximum height which corresponds to 10 to 60 %, preferably 25 to 50 % of the height of the feed channel. In particular, it is smaller than 50 %, preferably smaller than 40 %, particularly preferably smaller than 30 % of the height of the feed channel. So the cross-section through which the fluid flows is not narrowed too much, and it is prevented that in the fluid too high velocities are achieved which would result in a higher pressure loss across the cyclone.
- the at least one ramp at the upper wall of the feed channel does not extend along the whole, but preferably only along 20 to 60 %, particularly preferably 25 to 50 % of the width of the feed channel.
- the feed channel has a width which is smaller than 50 %, preferably smaller than 40 %, particularly preferably smaller than 30 % of the width of the feed channel.
- a ramp with this width can already be sufficient for diverting the fluid such that no particles can be accumulated in the low energy zone.
- the cross-section of the feed channel through which the fluid flows is not narrowed too much.
- the ramp may be allowed to extend across the whole width of the feed channel. Such a ramp arrangement can be manufactured in a particularly simple manner.
- the ramp at the housing cap may rest against an outer wall of the housing.
- the deflection of the circulating fluid in the region near the outer wall of the housing results particularly effectively in the fact that the particles are removed from the low energy zone.
- the ramp at the housing cap may have a curved design.
- the curvature of the ramp may be adjusted to the curvature of the outer wall of the housing.
- the ramp at the housing cap may have a width which corresponds to 20 to 80 %, preferably 40 to 60 % of the distance between the outer wall of the housing and the dip tube. In particular, it is smaller than 60 %, preferably smaller than 50 %, particularly preferably smaller than 40 % of the distance between the outer wall and the dip tube.
- a ramp having this width is sufficient for removing the particles from the low energy zone without reducing the cross-section through which the fluid flows too strong which would negatively affect the circulation movement.
- a ramp is arranged each, wherein it is possible that these ramps are connected via a, preferably cuboidal, connecting element.
- the ramp adjoining the inner wall of the feed channel effects the particles traveling at the inner path while the ramp at the housing cap adjoining the outer wall of the housing effects the particles traveling at the outer path.
- the complete boundary layer is separated from the housing cap so that no undesired particle extraction from the cyclone is effected via the boundary layer and the dip tube.
- the feed channel and the housing cap are characterized by a geometric, in particularly vertical displacement, so that also the respective ramps may be characterized by a geometric, in particularly vertical displacement.
- the design according to the present invention provides for improving the separation efficiency of the cyclone by 10 to 20%.

- the cyclone 1 is arranged such that the conical housing part 3 is oriented downwards into the direction of the gravitational field.
- the discharge port 4 is provided through which the particles and/or the liquid which has been extracted from the fluid stream can be discharged.
- the fluid stream together with the particles is fed through the feed channel 7 and the inlet opening 6 into the housing part 2. This, typically, is effected in a tangential manner (cf. Fig. 1 b) so that a circular movement of the fluid stream is induced.
- the fluid stream moves on a helical path from the inlet opening 6 into the direction of the conical region 3. Due to the centrifugal force the particles are transported to the outer wall of the cyclone 1 and there, by the effect of gravitation, they move into the direction of the discharge port 4.
- the purified gas or, in the case of a hydrocyclone, the purified liquid exits the cy- clone 1 upwards through the dip tube 12.
- first ramp 10a and in the interior of the cyclone housing 2, 3 a second ramp 1 1 a through which the fluid stream is diverted are provided.

- a gas stream for example from a blast furnace, together with solid particles contained therein is fed into the feed channel 7.
- the gas stream flows along the feed channel 7 into the direction of the cyclone housing 2, 3 (in the view of Fig. 1 a from the left side to the right side), and in the upper region of the feed channel 7 it is deflected downwards at the first ramp 10a so that it enters the cylindrical housing part 2 in a distance to the housing cap 5 which at least corresponds to the height of the first ramp 10a.
- a part of the gas and some particles are provided with a velocity component in downward direction which supports the transport of the particles into the direction of the discharge port and prevents that the particles enter the low energy zone 15 in the upper region of the cyclone 1 near the housing cap 5.
- a circular movement is initiated which through the centrifu- gal forces results in the separation of the particles from the gas stream. Particles which nevertheless have entered the low energy zone 15 near the housing cap 5 circulate around the dip tube 12.

- the same reference signs (optionally with indices a-f for the first to sixth embodiments) are used and reference is made to their preceding description.
- the embodiment of the Fig. 2a to 2c is characterized by an alternative arrange- ment of the ramp.
- the first ramp 10b in the feed channel 7 already reaches its maximum height before the inlet opening 6 of the cyclone housing 2, 3.
- the ramp 10b extends in a, preferably cuboidal, section 16 with constant height up to the inlet opening 6.
