Definitions
- the invention relates to a hydrocyclone system with several hydrocyclones according to the Preamble of claim 1.
- hydrocyclones are used to move liquids containing substances from different sinking behavior due to strong centrifugal forces fractionate. So it is e.g. possible in a pulp suspension, as used for Production of paper is used to concentrate and contain contaminants derived from the hydrocyclone by a reject connection. That of contaminants The exempt fraction, namely the accept, is led through the accept connection and further used.
- These processes are known per se, as is the fact that a good effect is only guaranteed if the hydrocyclones are not of a certain size exceed. In the case of a hydrocyclone system designed for larger throughputs is designed, therefore, a plurality - often even a large number - of hydrocyclones needed.
- the liquid to be cleaned then flows through them in parallel, which means that the liquid flow into a variety of smaller sub-flows must be divided. For this, e.g. Distribution devices, as follows still to be used.
- a hydrocyclone system is known from EP-A2-0 563 523.
- the one in it The hydrocyclones used are on a horizontal flow section connected by a partition extending in the direction of flow is divided. An inlet chamber and an accept material chamber are thus formed.
- a suitable distribution device is usually to be created so that the Distribution of liquid flows is even.
- hydraulic Disruptions, eddies or the like can be avoided.
- Hydrocyclone plants of this type is their simplicity to manufacture them at low cost can.
- the hydrocyclones should also be easily accessible and easy to maintain for maintenance purposes to be swapped. The fulfillment of all these requirements is with the existing ones Systems not solved satisfactorily.
- EP 0 658 648 A A system is known from EP 0 658 648 A in which a number of hydrocyclones is arranged approximately in a star shape around a hydraulic vibration damper.
- the Vibration dampers are known to be complex to build and operate. Also one other equipment shown in US 4,267,048 is complicated and requires a high one Manufacturing and assembly costs.
- the invention is therefore based on the object of creating a hydrocyclone system, with the simple distribution of an even distribution of those to be treated Liquid can be applied to the hydrocyclones.
- the distribution device designed according to the invention contains e.g. a relatively large one cylindrical tube or an oval flow part. This is described by the Partition into an inlet and an accept material room or in other cases in one Inlet and divided into a reject space.
- the flow part with the partition can easily created as a fully assembled unit and then with the openings for the Hydrocyclone connections are provided. In practice this is of great advantage because the introduction of two openings for a hydrocyclone in one Operation can take place, i.e. without moving the tool (e.g. the Laser cutter). Dimensional deviations are then much smaller than with tailors on separate pipes.
- the inflowing liquid e.g. a fiber suspension
- the inflowing liquid evenly distributed over the connected hydrocyclones.
- the backflow into the downstream of the partition The space of the distribution device is advantageously provided by the light material connection of the Hydrocyclone. In most cases this is close to the inlet connection.
- connections between the Flow part and the hydrocyclones executed as sealed plug connections his. This allows easy assembly or replacement of hydrocyclones.
- This type of connection is also inexpensive.
- the structure of the system is simple and clear. It is also easily possible to keep the main stream of liquids in maintain its direction; i.e. that the inflow and the accept or reject flow have the same direction.
- the hydrocyclone system shown in FIG. 1 receives the suspension to be cleaned a large feed line, which in the distribution and collection device 5 from below opens.
- This consists essentially of a cylindrical side wall 7 and is divided by a partition 9 across the flow direction. Upstream to this Partition 9, i.e. So on the inlet side, there are a number of openings 11 for Admission of the inlet connections 2 to the side of the distribution and collecting device 5 arranged hydrocyclones 1.
- the hydrocyclone 1 contains a central axis 10 which arranged parallel to the cylindrical side wall 7 and thus to the flow direction 6 is.
- the hydrocyclone 1 is constructed in such a way that the light part fraction is accepted as a good substance the accept connection 3 is discharged.
- the openings 12 in the cylindrical side wall 7 are located downstream of the partition 9. On this The side wall 7 is shown cut.
- the center lines 18 of the Inlet connection 2 and the center line 19 of the accept material connection 3 are in here mutually parallel planes, which in turn are perpendicular to the flow direction 6 in the Distribution and collection device 5 are. This leads to a particularly simple one Structure of the distribution and collection device 5, and the openings 11 and 12 can can be easily attached.
- the planes have a relatively small distance 20, preferably not more than 1.5 m. It can also be seen that the openings 11 and 12 are arranged on the same circumference 13 and 14, respectively.
- the construction of the hydrocyclone system shown in FIG. 1 is particularly simple. But there are deviations from this arrangement are easily conceivable.
- the Distribution device can also be oval or have a polygonal plan.
- the partition 9 obliquely, so that it has an angle ⁇ to Forms flow direction 6, which deviates from 90 °.
- the openings are located 11 or 12 with advantage on imaginary levels that are parallel to the partition 9.
- FIG. 2 schematically shows a hydrocyclone system according to the invention in a view from above.
- the principle of the presented invention enables a very simple even Distribution of the liquids in that the hydrocyclones 1 radiate with equal distance around the cylindrical side wall of the distribution device here are arranged.
- the partition not visible here lies horizontally between the Inlet connections 2 and the accept connections 3.
- Hydrocyclones can also be used so that the heavy fraction as a good substance and the light fraction is used as a reject. With such an application e.g. Specifically light contaminants separated from a paper fiber suspension.
- a system according to the invention can be used in that the accept material connection (3) 1 or 2 serves as reject connection. The accepted material then falls at the outlet for the Heavy fraction.
- Such circuits are known per se and therefore not here specially illustrated.
