Separation device for multiphase mixtures, preferably for suspensions containing sugar

The invention relates to a separating device for mixtures, in particular in the sugar industry.

Known separation devices for separating preferably sugary suspensions (DE-PS 12 53 674) consist of a vessel with a rectangular or ring-shaped Cross-section which is connected at its lower end to a tube with a smaller cross-section than the vessel. The tube forms vessels communicating with the vessel and forms an acute angle with its longer axis. In the vessel a bundle of plates is attached, which in its whole circumference in the suspension to be separated, which is separated is immersed.

The suspension first flows downwards through the pipe with a smaller cross-section and then in the opposite direction Direction through the bundle of plates upwards where the main separation takes place. The separated solid phase flows against the inflowing suspension along the Plates, and meets with this again. This results in a renewed mixing and thus an imperfect one Trennuna. The suppression of this undesirable phenomenon You can reduce it by increasing the size of the device, but a slight cloudiness cannot be entirely be eliminated.

The object of the invention is to provide a separating device for multiphase media, in particular for suspensions containing sugar, to create, which has a high degree of selectivity with a simple structure and operation and avoids cloudiness.

This object is achieved according to the invention in that a conical vessel with a system of plane-parallel inclined plates, a mixture distributor, has a collector and at the lower narrowed end of the vessel a blowdown device, the plane-parallel Plates two to fifty guide vanes are adjacent.

The subject of the invention is thus a device for mixture separation, which consists of a conical vessel, the at its upper extended and possibly cylindrical end part a system of plane-parallel inclined plates, a mixture distributor and a collector for e.g. the purified liquid phase. Narrowed at the bottom A solids or sludge drain is provided at the end of the vessel. Inside the vessel below or above the plane-parallel Plates are orientation blades in the form of flat or straight

arranged curved surfaces. The device serves to separate two phases in different combinations. To separate the liquid and solid phase, the orientation blades are under the separation zone and for separation of two liquids arranged above the separation zone. A combination of both arrangements is used for three-component separation.

The arrangement of the plane-parallel plates at the upper end of the vessel creates a cross flow of the entering Suspension compared to the already separated solid phase, resulting in a sharp separation of the solid phase and results in a clouding of a facility that is 300% smaller than that of comparable facilities.

The main effect is that the resistance value in the mixture flow at the orientation blades Resistance size on the separating plates exceeds, as a result of which the supplied mixture is forced to predominantly through to flow the space under the partition plates and thereby fully utilize their surfaces. This will have a higher separation effect Achieved by at least 10%, with otherwise the same extent of the facility.

In the following, exemplary embodiments of the invention are explained in more detail with reference to the drawing. Show it:

The illustrated separating device according to the invention consists of a conical vessel 1, which at its upper extended end a system of plane-parallel inclined plates 2, a suspension distributor 3, a collector 4 and a drain device at its lower narrowed end

5 has. On both sides, i.e. above and below the Plates 2 is a system of seven flat orientation blades

6 arranged.

The supplied mixture flows through the mixture distributor 3 into the system of planparallelaiPlatten 2, whereby it is continuously oriented by the blades 6 in the separation space 2, where the separation of two different liquid phases and solid phases occur. The liquid phases overflow separately into two channels in the collector 4 and the solid phase collects in the conical part 1 of the vessel, from which it is drained through the sludge drain 5 will.
