Definitions
- the invention relates to a tubular arrangement for passing a Paper pulp suspension, into which a second by a mixing device Liquid can be supplied.
- the second liquid is, for example, a suspension Liquid mixture and the like, which consist essentially of water, the In principle, however, the invention also applies to liquids and liquid mixtures can be used that are not based on an aqueous base.
- a second liquid is the first via nozzle pipes Liquid added.
- the first liquid flows through in relation to the Nozzle tubes with a large diameter tube.
- the nozzle pipes extend itself at a right angle to the longitudinal axis of the of the first liquid flowed through pipe.
- Hydraulic mixing devices are also known, but they are very expensive Control units and a variety of valves require. With these mixing devices the water accumulating in the sieving area of the paper machine, so-called White water, with a retention agent also dissolved in water Pipelines merged. You can then add this mixture again White water are added. This mixture is then placed in a tube for one Highly concentrated fiber suspension introduced, which is then the headbox is fed. Due to the tightness necessary with hydraulic mixing devices Pipe cross sections are very susceptible to faults.
- the additive In the first known solutions, the additive must be diluted with fresh water only with the third known solution is the contact time with the Dilution water short enough to be able to use it again from the sieve zone process water obtained.
- this object is achieved with an arrangement of the type mentioned at the beginning solved in that the mixing device has a plurality of openings and that the larger the openings around it, the larger the openings Partial volume flows of the pulp suspension are.
- the invention thus takes into account how the flow velocity of a liquid and the per unit time by a certain volume of a tubular body flowing amount of this liquid in relation to the entire flow cross-section of the body. Also one possibly through the Friction with the inside of the outer wall of the tubular body caused reduction in flow velocity in the outer edge area the size of the openings in the mixing device take into account that these are made smaller again.
- the invention results in a lower level than in the prior art Effort when realizing the addition of an additive or generally when adding a second liquid to another liquid because fewer valves and fewer flow meters are needed.
- this object is achieved with an arrangement of the type mentioned at the beginning also solved in that the mixing device has a plurality of openings for Mixing in the second liquid and that the distances between the openings all the more are smaller, the larger the partial volume flows flowing around the openings Paper pulp suspension are.
- This measure also ensures uniform mixing of the two media across the entire diameter of the tubular body through which it flow through, guaranteed.
- Realizable embodiment of the invention is that the Mixing device a plurality of openings for mixing the second Has liquid and that the angle of inflow from the openings out flowing second liquid according to the flowing around it Partial volume flows of the pulp suspension are arranged to each other.
- angles at which the second liquid enters the Paper pulp suspension flows out be chosen so that a stronger Mixing takes place in the area in which a larger part of the volume Paper pulp suspension is present, and that there is a weaker mixing there is realized where a smaller sub-volume of the pulp suspension is available.
- the mixing device as at least one metering lance is formed with at least one row of bores.
- the mixing device as at least one metering lance is formed with at least one row of bores.
- the jacket or tube wall introduces at least one metering lance, which a variety of Has holes, especially of bores. It is crucial, however, that the Dosing lance larger and / or more closely spaced holes near the Has outer circumference of the tubular arrangement than in the middle.
- the holes in the dosing lance can either be in one or more rows arrange; the openings in the rows can also extend over the circumference of the metering lance each be staggered; for example, the openings neighboring rows can be arranged at an angle of 60 ° to each other.
- Dosing lances are available that are at an acute or obtuse angle, in particular at a 90 ° angle to one another.
- Metering lances are also used with advantage, providing a connection for the feed of dilution water. This allows the concentration of one of the Control the additives to be added to pulp suspension even better.
- a water jet pump or according to Art a water jet pump trained connection.
- a static mixer can advantageously also be used immediately before at least one of the metering lances must be attached.
- the at least one metering lance is rotatably mounted in the arrangement. So that Dosing lance with that for the second liquid, i.e. especially for the additive, maximum permissible shear rate both in and against the flow direction in Main stream of the pulp suspension are rotated. It is understood that the Dosing lances can also be adjusted by motor. This measure also leaves the mixing of the two liquids influence each other.
- the invention also relates to a method for passing a Paper pulp suspension through a tubular arrangement, with a Mixing device is supplied with a second liquid.
- this method is designed so that the second liquid by adapted to the respective partial volume flow of the paper pulp suspension Sizes of openings in the mixer into the tubular assembly is introduced.
- the mixing of the Realize both liquids so that the second liquid passes through to the Adjusted distances of the respective partial volume flow of the paper pulp suspension Openings in the mixing device is introduced into the tubular arrangement.
- the second liquid immediately before it is placed in a pipeline or metering lance from which it is injected the pulp suspension is mixed in via the kinetics of an additive and of a diluent, from which the second liquid is composed, on the for mixing between the pulp suspension and the second Liquid required mixing energy is set.
- the diluent as the in particular water or process water is used, with a Speed of 1 to 4 m / s flows that the additive at a speed of 2 to 10 m / s flows and that the second liquid composed of it with a Velocity of 0.2 to 5 m / s flows into the pulp suspension.
- a pulp suspension is promoted.
- Dosing lances 2, 3 mixed a second liquid.
- the metering lances 2, 3 are each connected to supply lines 6 via connecting pieces 4, 5, via which the second Liquid is supplied.
- Each of the metering lances 2, 3 has at least one row of openings 7 equipped, a large distance to the center of the tube arrangement 1 and outer wall 10 of the tube assembly 1 towards a smaller distance. there the distances of the openings 7 to one another are chosen such that over all partial volumes the pulp suspension in the tube arrangement 1 a uniform interference the second liquid takes place. If one divides the cross-sectional area of the Pipe arrangement 1 in concentric rings around the center of the pipe arrangement 1 which also cross the metering lances 2, 3, you can see that the outside of the rings each occupies a larger area than the ring that is adjacent to the inside. Accordingly, more openings 7 in the metering lance must also be provided for the outer ring 2, 3 may be provided.
- the metering lances 2, 3 can also be designed such that they have only one row of openings 7 towards the center of the tube arrangement 1, while they have two, three or more rows of openings 7 towards the outside, so that the number the rows of openings 7 increases towards the outside. In this case, does not have to necessarily also the distance of the openings 7 in one row to the outside decrease.
- the metering lance 2 (Fig. 2) is closed at one end via a stopper 8 while it is connected at its other end to a line 11 via a connection 9, which can be opened or closed and is used to control the metering lance 2 rinse to remove debris from it. During operation, the Line 11 kept closed.
- dilution water is supplied via the feed line 6, while via a further feed line 12 is fed an additive, which in a connection or Mixer 13 is mixed with the dilution water to the second liquid form, which are then introduced via the connecting piece 4 into the metering lance 2 and out this is introduced into the tube arrangement 1 via the openings 7.
- the dosing lance 3 is constructed like the dosing lance 2.
- FIG. 3 there are two in the tube arrangement 1 Dispensing lances 14, 15 are arranged, each of which has openings 16.
- the openings 16 are small in the area of the central axis of the tube arrangement 1 and are in the direction to the outer wall 10 always larger. This measure also achieves that in the outer area more of the second liquid in the Paper pulp suspension is mixed in as in the inner area because in the outer Area a larger volume flow of the second liquid flows.
- the metering lances 14, 15 are equipped with several rows of openings 16 can be, the rows not extending over the entire length of the metering lances 14, 15 must extend, but for example only in the wall 10 facing Area can be arranged to supply more of the second liquid there than in the middle of the pipe arrangement 1.
- the tube arrangement 1 (FIG. 4) has 10 flange covers on the outside of its wall 17, 18, 19, 20, by means of which the metering lances 2, 3 and 14, 15 crossed are held to each other. There can be any number of dosing lances in the Pipe arrangement 1 may be present, which is then preferably symmetrical about the Cross section are distributed.
