Definitions
- the invention is directed to a method for optimizing a centrifugal separator, in particular a recycling cyclone in a high-temperature gasifier.
- Centrifugal separators are known in very different designs.
- DE 103 46 692 A1 shows a droplet separator which, in the transition to the hopper area, has swirl vanes on the outside edge of the immersion pipe terminating there in order to achieve a rotation of the incoming gas flow in the hopper.
- DE 102 05 981 A1 shows activation and deactivation of cyclones
- DE 195 16 817 C1 shows a cyclone with additional elements, such as a spray electrode.
- High-temperature gasifiers were developed to improve the use of, for example, lignite by means of a fluidized-bed gasification process using a so-called high-temperature Winkler gasifier HTW as a further development of Winkler coal gasification, which originally operated at ambient pressure.
- the advantages lie mainly in the better utilization of raw materials, the considerably larger carburetor capacity for large-scale plants and in the avoidance of the formation of by-products.
- a disadvantage of this procedure is, inter alia, that the separation efficiency of the recycling cyclone is not particularly pronounced, which has the consequence that you have to switch cost-intensive hot gas filter behind the cyclone and raw gas cooler. To make matters worse, that in the hot gas filter separated dust is still high amounts of carbon. This dust can thus not be landfilled, but must either be returned to the carburetor via lines and screws or burned at great expense in a separate boiler by means of auxiliary fuel.
- this object is achieved according to a variant of the invention in that a local increase in the centrifugal force is made by internals on the dip tube of the centrifugal.
- a variant of the optimization option according to the invention consists in the fact that a mechanical grain enlargement of the particles to be separated is carried out by an upstream connection of an agglomerator in the inlet region of the centrifugal separator.
- An agglomerator influences the particle size by increasing the collision rate between large and small particles in the inlet area of the cyclone, which significantly improves the degree of separation.
- agglomeration devices are known, see for example the DE
- cyclones work optimally only in very limited operating conditions, For example, with dusts an optimal tangential entry velocity into the cyclone is 10 m / s, the performance is subject to fluctuations during load changes.
- the invention intervenes by changing the cross section of the Zentrifugalabscheidereintritt, said cross-sectional change can be done in very different ways, as indicated below.
- variable cross-sectional change is achieved that the design speed of the cyclone can always be kept constant.
- the invention also provides a device or a centrifugal separator, which is characterized in that a flow-guiding element narrowing the flow channel of the centrifugal separator is provided on the dip tube.
- a narrowing flow element may, as the invention provides, be designed as a cup-shaped guide plate.
- the eccentric, shell-shaped baffle is arranged approximately opposite the gas inlet at the outer region of the dip tube, the baffle pulled to below the lower edge of the gas inlet channel and then to the lower dip tube end rejuvenating the pipe shape.
- the position of the baffle may also vary depending on the design of the centrifugal separator.
- an agglomerator is provided at the inlet of the centrifugal separator, which is supported by a plurality of tubular conveyors passing through the flow channel. mige Strömungsstörianan is formed. These tubular Strömungsstörimplantation can be installed horizontally, vertically or at an angle in the flow channel.
- the invention also provides, in a further embodiment, for the inlet flow channel to be equipped with a movable wall surface or a ceramic slide plate which changes the channel cross-section, with embodiments being able to consist therein in that the horizontally or vertically movable wall surface is designed as a slide or as a wall element curved in the transition region to the centrifuge.
- FIG. 2 to 7 simplified representations of a centrifugal separator
- a system of high-temperature Winkler gasification is shown in simplified form with a carburetor 1, the feed material is supplied via feed tank 2.
- the bottom product is discharged at 3, z. B. by means of a screw conveyor 4.
- the gas acts on a centrifugal separator 5, wherein the solid particles are passed via the line 6 back into the carburetor 1, the gas is removed for further processing via a line 7.
- FIGS. 2 to 7 variants of the influence on the flow in the centrifugal separator 5 are shown:
- Fig. 2 shows the supply of the mixture of solids and gases (arrow 8) in the centrifugal separator 5, wherein the mixture flows around the dip tube 9.
- the dip tube 9 has a flow guide 10, which is welded as a curved baffle on the dip tube 9 or otherwise secured there.
- the baffle 10 tapers, designated in its lower part with 10a, such that at the end of the dip tube 9, the original cross-sectional area of the flow channel is reached again.
- the cleaned gas leaves the centrifugal separator 5 via the pipe 7, which is indicated by an arrow 11.
- the solid particles leave the separator down, which is indicated by an arrow 12.
- FIG. 2 reproduced for better representation at the intended location. This does not have to correspond to the actual installation position.
- FIG. 3 In contrast to Fig. 2 are in the embodiment of FIG. 3 for the formation of an agglomerator, indicated generally at 13, incorporated in the inlet nozzle 14 of the centrifugal 5 tubular Strömungsstörimplantation 15, not only, as shown here, horizontal, but also vertically or diagonally in the inlet channel 14 may be positioned.
- a variant is shown in order to change the cross section of the inlet channel 14 of the centrifugal separator 5, namely by a raised and lowered bottom plate, for. B. also formed as a ceramic plate, which is designated 18, the possibility of movement is indicated by a double arrow 19.
- the ceramic plate designated here by 20
- the ceramic plate can be pivoted vertically to change the cross section, which is indicated by a double arrow 21.
- FIG. 7 also shows the possibility of reducing the cross-section in the inlet region to the centrifugal separator 5 by means of a plate 22 adapted to the curved wall of the separator, the movement being indicated by a double arrow 23.
- the individual measures can also be performed in combination, for example at the same time a cross-sectional constriction of the inlet channel 14 by corresponding ceramic plates 18, 20 or 22 in conjunction with an agglomerator 13 and a flow baffle 10, 10a, to indicate only one possible variation ,
