Description
SPECIFICATION
Moving bed filter for the purification of gaseous and/or vaporous media
The invention is based on a moving bed filter for the purification of flowing media of the type with a layer of contact agent through which the medium to be purified flows vertically upwards and with at least one porous flow-guide member device controlling the mass flow, arranged in the region of the layer over the entire cross-section and one shut-off device.
In known moving bed filters, a layer of contact agent which is constructed as a fluid loose material is located between an inlet and outlet opening for the medium to be purified. The saturated contact agent flows downwards and fresh adsorbent is accordingly added from above. The flow medium flows from below through the layer of granular contact agent, in which case the active adsorbent constantly accumulates the substances to be retained from the flowing gas or liquid medium, in an upwards direction.
In order to be able to control the necessary discharge quantity of contact agent, it is known to provide roof-shaped concealed, open flow-guide members over the entire cross-section, in or below the layer of contact agent, which members can be opened and closed as desired on the underside.
However, with these known flow-guide members, an irregular exchange of the layer of loose material occurs when filling and discharging in an upwards direction,which occurs due to slipping and sticking areas forming automatically and displacement forces with nuclear flow effects occurring in the pouring, which may also be initiated by outstripping processes between the saturated and unsaturated contact agent. Due to this irregular exchange of layer, the contact agent is not fully utilized, which has economic drawbacks. It is also a disadvantage that the flow-guide members arranged in one direction are very complicated and expensive to manufacture and assemble. The discharge of small quantities of contact agent is not possible on account of the coarse flow-guide member structure without disturbing the structure of the layer.
Therefore, it is the object of the invention to provide simple and economical flow-guide member devices which can be shut off, which allow a uniform and above all thin-layered exchange of layer of the contact agent and in which in the open condition, a removal of the layers of less than +5% occurs, in order to ensure total utilisation of the adsorbent.
According to the present invention there is provided moving bed filterforthe purification of gaseous and/or vaporous media with a layer of contact agent through which the medium to be purified flows vertically upwards and with at least one porous flow-guide member device controlling the mass flow, arranged in the region of the layer over the entire cross-section and one shut-off device, wherein the flow-guide member device and the shut-off device are constructed as at least one flow-guide member apertured plate and at least one shut-off apertured plate which are arranged at right angles to the flow direction and which comprise hole punched in a downwards direction and whereof the raised, closed parts taper to a point in an upwards direction.
The manufacture of the flow-guide members in the form of apertured plates punched in a downwards direction is very simple, it takes place in known manner for example by means of a simple punching and deep-drawing process. The particular construction of the apertured plates with holes punched in a downwards direction and with the bending lines of the edges of the holes in contact with each other, as a variation of the commercially available type of so called washing machine drum plates with raised, closed parts tapering to a point in an upwards direction and the plurality of the punched holes located close beside each other, prevent the formation of slipping and sticking areas with nuclear flow disturbances, when the contact agent is discharged. When the layers of contact agent are discharged, no outstripping processes of saturated and unsaturated adsorbent occur.The uniform lowering and thus the removal of the layers of less than + 5% is ensured by the relatively great number of funnel-shaped holes and their favourable arrangement one with respect to the other.
One embodiment of the moving bed filter according to the invention is illustrated in the drawings and is described in detail in the following description, in which:
Figure 1 is a section through one embodiment of the moving bed filter according to the invention with stationary and horizontally movable apertured plate arrangements;
Figure 2 is a plan view of a flow-guide member apertured plate and a shut-off apertured plate in the closed and open condition and
Figure 3 is a section through the superimposed arrangement of flow-guide member apertured plate and shut-off apertured plate in the closed and open condition.
In Figure 1,the reference numeral 1 designates the container of the moving bed filter. Attached to the container 1 are a supply pipe 2 and a discharge pipe 3, through which the flowing medium, for example gas or liquid, is supplied or discharged. The direction of flow is indicated by the arrows 4. Arranged in the container 1 are several apertured plate grate surfaces 5,6,7,8, which control the uniform discharge of contact agent in a downwards direction. The upper apertured plate grate surface 5 consists of a fixed or stationary flow-guide member apertured plate 9 and of a horizontally movable shut-off apertured plate 10 located therebelow. The displacement of the shut-off apertured plate 10 takes place by way of a rotary drive 11. An individual stationary apertured plate 6 is provided below this apertured plate grate surface 5 at some distance therefrom.Located in turn below the stationary apertured plate 6, at some distance therefrom, is the apertured plate grate surface 7, which corresponds to the apertured plate grate surface 5. Attached below a stationary flow-guide member apertured plate 12 is a similar dispiaceable shut-off apertured plate 13, which is moved by the rotary drive 11 by way of a lever and connecting rod.
A further stationary apertured plate 8 is provided below the apertured plate grate surface 7, at some distance therefrom.
The fresh contact agent 14 is introduced in a manner which is not shown from above into the container 1 and settles as a loose layer on the apertured plate grate surface 5 and in the shut-off condition forms the supply of contact agent. A cavity 15 forms between the apertured plate grate surface 5 and apertured plate 6, which cavity is connected to the discharge pipe 3 for the flowing medium to be processed. The space between the apertured plate 6 and apertured plate grate surface 7 is filled with contact agent, which forms a layer 16, which is referred to as the working layer. A further cavity 17 forms between the apertured plate grate surface 7 and stationary apertured plate 8, which cavity is connected to the supply pipe 2 for the flowing medium.
Located below the apertured plate 8 is a discharge funnel 18, which serves to receive and collect and remove the saturated contact agent 19. Due to the horizontal displacement of the shut-off apertured plate 13 by means of the rotary drive 11, the apertured plate grate surface 7 is briefly opened and saturated adsorbent from the contact agent working layer 16 flows through the openings by way of the stationary apertured plate 8 into the discharge funnel 18. By way of primary measuring sensors for the filling level or throughflow (not shown), which may be provided in the region of the apertured plate grate surface 5,7 and/or the stationary apertured plate 6,8, it is possible to measure the respective intake and discharge quahtity, by means of which the open and closed times of the apertured plate grate surface 7, respectively the rotary drive 11, can be controlled.The rotary drive 11 of the upper apertured plate grate surface 5 is controlled accordingly, in order that the contact agent supply 14 is able to deliver to the working layer 16 the quantity of contact agent which was discharged downwards as saturated contact agent 19. In order to be able to measure the differential quantity of the contact agent, two primary measuring elements for measuring the throughflow quantity (not shown) may be provided in the region of the apertured plate 6 forming the upper limit of the working layer 16.
In Figure 2, which is a plan view of the flow-guide member apertured plate 9,12 and the shut-off apertured plate 10,13 in the closed position on the left and the open position on the right and in Figure 3, which is a partial section through the corresponding apertured plate grate surface 5,7 in the open and closed positions, the shape of the corresponding apertured plates is shown in detail. Also, the shape of the individual stationary apertured plates 6,8 corresponds to that of the flowguide member or shut-off apertured plates 9,10,12,13. The punched holes 20 should lie as close as possible to each other.
In the present case, the punched holes 20 are distributed in such a way that the bending lines 21 of the edges of the holes are in contact with each other.
According to Figure 3, the non-apertured, raised parts 22 taper to a point and are rounded somewhat at the top. Due to this construction and due to the plurality of punched holes 20 lying close beside each other, there are no surfaces on which the granular contact agent is able to settle, thus promoting the uniform discharge of contact agent over large surface in the plane of the layer. The punched holes 20 are arranged staggered with respect to each other. In
Figures 2 and 3, the two different end positions of the apertured plate grate surfaces 5,7 are illustrated.
The respective flow-guide member apertured plates and shut-off apertured plates 9, 12 and 10,13 are located one above the other, in which case in the left-hand illustration, the closed parts 22 are located opposite the punched holes 20, this means that the two apertured plates 9,12 and 10,13 are offset with respect to each other by the distance between holes in the horizontal direction, (by the so called spacing dimension). This position is the shut-off position, this means that the closed, raised parts 22 of the shut-off apertured plates 10,13 close off the punched holes 20 of the flow-guide member apertured plates 9,12 in such a way that the granular contact agent from the contact agent supply 14 or the working layer 16 cannot flow through the apertured plate grate surfaces 5,7, whereas the flow medium can flow vertically upwards in the direction of the arrows 23.In the shut-off position, in which the closed parts 22, which form an approximate triangular profile 24, are located opposite the respective punched holes 20, three semi-circular slots remain in each individual hole. For complete blocking, these slots are preferably smaller than the smallest granular and fluid particles of contact agent. However, it is sufficient if the slots are somewhat larger than the smallest granular particles of contact agent, since the latter become hooked together, so that a throughflow is not possible even with relatively large slots. Complete blocking is always ensured if adjacent bending lines 21 of the punched holes 20 of the apertured plates are in mutual contact.In the illustrations on the right of Figures 2 and 3, the apertured plate grate surfaces 5,7 are shown in their open positions, in which case the perforations 20 and the closed, raised parts 22 of the corresponding flow-guide member apertured plates 9,12 and of the shut-off apertured plates 10,13 lie respectively opposite each other.
The contact agent from the contact agent supply 14 or the working layer 16 flows undisturbed in a downwards direction, whereas the flowing medium flows in an upwards direction according to the arrow 23 even during the discharge process, so that the operation of the filter is not impaired or interrupted under any conditions.
The following dimensions for the apertured plates are given by way of example. The apertured plates should have an approximate material thickness of 2 to 3 mm and the punched round holes 20 a diameter of approximately 10 to 15 mm or greater. A height of approximately 3 to 4 mm is provided for the closed, raised parts 22, forming an approximate triangular profile 24. The shortest centre to centre distance, which corresponds to the spacing dimension and which determines the displacement between the open and closed position of the apertured plate grate surfaces 5,7, should amount to approximately 18 mm. However, this may also be greater. As a whole, these dimensions are given solely by way of example, naturally other smaller or larger, appropriate dimensions could also be chosen.
Apart from the close distribution of holes which is otherwise not normal and the deep punching, the apertured plates are in principle commercially available plates, which are known on the market as washing machine drum plates. However, if the desired dimensions with the close distribution are not available, they can also be produced in a simple manner for example by means of a simple punching and deep-drawing method according to the normal principle. Aluminium, high-grade steel, galvanized steel plate or plastics material can be provided as the materials.
In the example according to Figures 2 and 3, round holes are provided for the holes 20 of the apertured plates, but polygonal holes could also be provided, for example square holes with cross-pieces having a thickness of approximately 1.5 to 2 mm, in which case the side edges should preferably have a length of 8 to 10 mm or more and be arranged selectively in a row or staggered with respect to each other. In general it should be stated that in the case of flat plates provided with square holes or generally flat apertured plates, the web width between the holes should be approximately S the average diameter of the granular material. The diameter of the holes or the edge length of square or rectangular holes should be approximately > five times the average diameter of the granular material.With these dimensions, the formation of a bridge between several grains over one or more holes is largely impossible, so that uniform discharge of the granular material is achieved. In the moving bed filter according to the invention, a flow speed of approximately 0.4 metre/ sec is achieved. Due to this there is no danger of a transition from solid bed to fluidized bed, since there are no considerable contractions of cross-section due to the above mentioned dimensions.
The so called "jumping speed", at which there is a danger of a transition from solid bed to fluidized bed, occurs at approximately 0.8 metres/sec with granularA - carbon, according to citations.
In the embodiment according to Figure 1, several apertured plate grate surfaces 5,7 and stationary apertured plates 6,8 are arranged one above the other. This arrangement is chosen solely by way of example, it is sufficient if a horizontal apertured plate grate surface 7 with a flow-guide member apertured plate 12 and with a movable shut-off apertured plate 13 is provided, above which the resting working layer or the respective supply of contact agent is located. In this case, a stationary apertured plate corresponding to the apertured plate 6 may be provided by way of addition located thereabove, which serves as a distributor apertured plate.In order to improve the uniform discharge of granular material, the surface of the layer of contact agent or of the working layer, through which the throughflow medium flows in an upwards direction, should be plane parallel at its horizontal lower face. In order to achieve this plane parallel surface, means may be provided for flattening heaped cones of adsorption agents or a metered, free-falling mass of contact agent on stratified moving bed filling material. This device for flattening or achieving a plane parallel surface may consist either of a motor spindle able to rotate coaxially, which is equipped with blades in the manner of a propeller and smooths the face of the material horizontally on the surface or semi-circular slides are drawn over the surface of the material or at right angles over a distribution apertured plate corresponding to the stationary apertured plate 6, which slides replace the discharge portions of the contact agent by measuring the filling level by way of a delivery of fluid material and spread it out or smooth it on the surface. The quantity of used adsorbent discharged is replaced by the slide automatically at the same time from a fresh adsorbent reservoir, in which case the slide may be controlled by a pulse control device.
