    Separator and separator use {SEPARATING DEVICE AND USE THEREOF}
    [2] The most important of the mechanical separation methods is the gravity method and the resulting precipitation. The device for the segregation of solid particles from a liquid consists, for example, of a sandbox or sedimentation tank as used in conventional purification plants. There are three main types of structures for different settling tanks:
    [3] Rectangular tank with horizontal throughflow and a nearly horizontal tank base,
    [4] Round tanks with horizontal flow through from center to edge and almost horizontal tank base and
    [5] There is a funnel tank with vertical flow through which sludge is removed from the tip of the funnel.
    [6] One particular type of separator is a layered separator in which the purification zone in the settling tank or container is increased by the installation of an intermediate base (layered) arranged at an angle. This type of layered separator is used for the purification of industrial or industrial sewage, especially when the bottom space for sedimentation tanks is small.
    [7] It is uncertain whether the solid particles to be separated will precipitate, for example, on the funnel tank and the tank base or layer or wall attached thereto. Therefore, an adhesion is formed between the solid particles and the precipitater wall or base and also between the solid particles which are continuously and simultaneously precipitated.
    [8] For this reason, the surface of the settler must be completely clean.
    [9] According to aspects of the art, a suction clearer, a sludge scraper or a flat strip clearer was used as the purifier. Because of the oblique position of the funnel wall, the funnel tank generally does not have a purifier, as it can be assumed that the sediment slides into the sludge outlet centered at the bottom. Nevertheless, however, practically also in a funnel tank, a problem arises in which solid particles settle on obliquely positioned walls to form a sludge layer.
    [1] The present invention provides solid particles from a liquid having a first wall, a precipitator having a liquid inlet for supplying liquid to the precipitator and an outlet disposed at the lower end of the precipitator for the solid particles separated by sludge according to claim 1. A separator for separating. Separators of this type, such as, for example, layered separators, have been used for the physical separation or segregation of liquid or solid particles from gas or liquid streams.
    [20] 1 is a separator according to the present invention;
    [21] 2 is another separator according to the present invention; And
    [22] 3 is another separator according to the invention.
    [10] It is therefore an object of the present invention to produce a device for separating solid particles from a liquid, in which deposits on the walls of the device can be removed or prevented in a simple and economic way.
    [11] This object can be achieved by an apparatus according to the embodiment of claim 1 which combines the above features. In addition, the use of the device is given according to claim 19. Advantageous refinements of the device according to the invention and the use according to the invention are described in the dependent claims.
    [12] The separator according to the invention has a precipitator having a first outer wall, a liquid inlet for the supply of liquid to the precipitator and an outlet arranged at the lower end of the precipitator for solid particles separated into sediment. In the case of a settler, for example, a funnel tank known in the art, solid particles settle on the wall surface of the settler and ideally slide down from the wall towards the outlet for the sediment. According to the invention, a second movable wall is located in the first wall. The second wall replaces the function of the first wall with respect to the precipitation of the precipitate, so that the precipitate is essentially deposited on the second movable wall. As a result of the fact that the wall is movable, when the wall is moving due to, for example, vibration, shaking motion, etc., the bond between the respective solid particles in the precipitate or the bond between the solid particles of the precipitate and the wall is temporary. Can be removed. As a result, the sediment sludge attached to the wall slides down towards the outlet for the sediment by gravity. Due to only slight movement of the second movable wall, the sediment is not mixed, ie the interface between the sediment and the liquid is not substantially disturbed so that the sedimentation effect of the sediment is not reduced.
    [13] The settler is a funnel tank which has a trapezoidal cross section extending advantageously towards the outlet and which can also extend in the longitudinal direction (ie perpendicular to the trapezoidal cross section). However, the precipitator is preferably conical and the opening angle of the first wall and the opening angle of the second wall are adapted to correspond to each other such that the two walls are directly adjacent to each other. The two walls can be arranged loosely with respect to each other and the second wall on the upper circumferential edge also has a stabilizing ring attachment, in the case of a conical cross section. The second wall can for example be suspended in this circumferential attachment and can also be connected to a device for moving the wall through the circumferential attachment. In a particularly simple way, if the circumferential attachment is frictionally connected to the two push / pull rods, since the parts of the push / pull rods are set in opposite motion by the eccentric shafts at the points facing each other, the second wall Can vibrate or shake. Sludge deposited on the second wall slipping down towards the sediment outlet can be achieved by this simple mechanical arrangement. The shaking or vibration of the second wall can be brought about continuously or periodically at the same or irregular time intervals.
    [14] A suction pump can be arranged at the outlet for the sediment, for example a volume suction pump to accelerate the discharge of the sediment sludge.
    [15] The separator according to the invention can also be formed as a layer separator, where also, likewise, the layered structure on which the solid particles have been precipitated can be formed in a manner corresponding to the second wall in a movable fashion.
    [16] Both the second movable wall and the stratified structure are subjected to movements (shakes, vibrations, etc.) to be overcome between solid particles of the precipitate, for example, by controlling the oscillation frequency or oscillation amplitude or between the precipitate and the wall or the stratified structure. Etc.) to a controllable drive against vibration of the second wall or layered structure.
    [17] If the liquid inlet is arranged in such a way that the liquid is introduced tangentially with respect to the circumferential line of the second wall, the slow rotational motion required for the solid particles to settle can occur in the settling tank.
    [18] Precipitators according to the invention can in particular be used for the purification of any type of wastewater. In particular, in the case of quenching the waste gas by water spray cooling, carbon particle suspensions are produced and can be purified particularly effectively by the separator according to the invention. This type of wastewater from the quenching of the waste gas arises from the gasification of waste materials of household and / or industrial, for example according to the heat selection method.
    [19] Some examples of separators according to the invention are described next.
    [23] 1 shows a settler 1 having a suction port 3 for supplying wastewater to be purified. In addition, the settler has a funnel-shaped cross section (outer cone 6) in the lower region of the wall 2, which is tapered into the outlet 4. The outlet 4 serves for the discharge of the settled sludge. According to the invention, the second wall 7 is arranged along the inner side of the outer cone 6 in the settler, which wall has the same conical cross section with the same opening angle as that of the outer cone 6. have. At the upper end of the inner cone 7, a stable attachment ring 8 is fixed to which the inner cone 7 is fixed. Since the part of the inner cone is not fixed to the outer wall 2 or the outer cone 6 of the settler 1, the inner cone 7 therefore lies loosely on the outer cone 6.
    [24] The inner cone 7 can be shaken and the device for shaking the inner cone 7 which engages the stabilization ring 8 is not shown. The device can be, for example, two push / pull rods that are replaced via eccentrics in opposite directions in opposite directions of vibration / shake. By shaking the inner cone 7, the solid sludge deposited in the inner cone 7 slides into the outlet 4, so that the inner surface of the settler can be purified.
    [25] As can be seen in FIG. 1, the intermediate space between the inner cone 7 and the outer cone 6 is also filled with the liquid to be purified. Here, also, the shaking motion of the inner cone 7 can be transmitted to the sludge particles deposited in the outer cone 6, so that the outer cone 6 can also be purified by the shaking motion of the inner cone 7.
    [26] Of the inner cone 7 in such a way that the adhesion between the respective solid particles or between the precipitated solid particles and the wall of the inner cone 7 can be temporarily removed so that the precipitate can slide down into the outlet 4. The shaking motion is formed. However, it should be noted that the swinging motion should not be strong enough to remix the sludge and invalidate the purification effect of the settler.
    [27] The suction port 3 in the upper region of the settler 1 is arranged in such a way that the liquid is introduced into the settler tangentially with respect to the circumferential line of the outer wall 2 of the settler 1. Thus, a slow rotational movement of the liquid in the settler occurs to improve the settling effect.
    [28] It is not shown here because the outlet for the clarified liquid can be arranged in a conventional manner in the settler 1.
    [29] Figure 2 shows another precipitator 1 according to the invention, and the same elements have the same reference numerals as in Figure 1 and will not be described here any further. In contrast to FIG. 1, the precipitator of FIG. 2 has a layered structure 5 which further increases the precipitation surface of the precipitator. This layered structure can be oscillated with respect to this part in the same manner as the second wall 7 so that the surface of the layered structure is cleaned.
    [30] FIG. 3 shows yet another settler according to the invention, here also their arrangement or function has not been described further since the same elements bear the same reference numerals as in FIG. 1. In contrast to FIG. 1, the inner wall extends over the inner cone 7 along the first outer wall 2 of the settler, and the stable attachment ring 8 is arranged at the upper end of the vertically standing portion of the inner wall 7. have. Moreover, the layered structure 5 is arranged in the upper non-trapezoidal part of the settler as shown in FIG. This layered structure 5 can also be shaken again to purify the layered structure 5 to which the sediment sludge adheres.
    [31] The separator according to the invention has a precipitator having a first outer wall, a liquid inlet for the supply of liquid to the precipitator and an outlet arranged at the lower end of the precipitator for solid particles separated into sediment. In the case of a settler, for example, a funnel tank known in the art, solid particles settle on the wall surface of the settler and ideally slide down from the wall towards the outlet for the sediment. According to the invention, a second movable wall is located in the first wall. The second wall replaces the function of the first wall with respect to the precipitation of the precipitate, so that the precipitate is essentially deposited on the second movable wall. As a result of the fact that the wall is movable, when the wall is moving due to, for example, vibration, shaking motion, etc., the bond between the respective solid particles in the precipitate or the bond between the solid particles of the precipitate and the wall is temporary. Can be removed. As a result, the sediment sludge attached to the wall slides down towards the outlet for the sediment by gravity. Due to only slight movement of the second movable wall, the sediment is not mixed, ie the interface between the sediment and the liquid is not substantially disturbed so that the sedimentation effect of the sediment is not reduced.
