Definitions

  • the invention concerns an apparatus for introducing a first fluid into a second fluid which is flowing in a pipe, which apparatus consists of a pipe-shaped body with a through-flow channel for the said second fluid of essentially constant cross-sectional area, one or more chambers which extend round at least the majority of the circumference of the through-flow channel along at least a part of its longitudinal extent, a connection for supplying the first fluid to the said chambers from a pressure source, in which a series of through-holes is arranged in the said pipe-shaped body in the region of the said one or more chambers, through which holes the first fluid can be directed into the second fluid which is flowing through the said through-flow channel under the influence of the difference in pressure between the said chambers and the said through-flow channel.
  • the invention is advantageously applied to the admixing of steam into a flow of cellulose pulp.
  • SE 502 393 The apparatus described in SE 502 393 is used primarily as a mixer in the bleaching departments in the cellulose factories for the admixing of steam into a pulp suspension in order to raise its temperature to a level which is required to ensure that a specific reaction takes place with the desired speed in a subsequent bleaching step.
  • the apparatus can give good admixing of steam into the suspension, but it is difficult to control the quantity of steam needed for temperature control without reducing the effectiveness of the admixing at the same time.
  • the steam admixing is regulated conventionally by means of a valve in the steam pipe to the said chamber.
  • a characterizing feature of SE 468 341 is that the through-flow pipe is made as a narrow, ring-shaped passage for the second fluid, which is considered to promote a good admixing effect.
  • the construction entails certain problems. This is probably due to the fact that the first fluid, when it is injected at high speed into the second fluid flowing through the narrow space, interacts with the constricting body installed in the through-flow channel and that, probably due to resonance phenomena, serious vibration can occur in the apparatus.
  • the purpose of the invention is to provide Apparatus which is not burdened with the limitations or disadvantages mentioned above: more precisely, the invention aims to provide Apparatus which gives good admixing of the first medium into the second medium and to ensure that good heat distribution is obtained in the downstream pipe, i.e. that very small temperature differences are obtained in an arbitrarily chosen cross section of the downstream pipe.
  • Another positive effect of the apparatus is the generation of relatively little vibrations and provision of a good facility for adjustable and controllable admixing of a first medium into a second medium.
  • the apparatus which shall be described in the following, is developed and designed to be used for the admixing of steam into a suspension of cellulose fibres (pulp) in a pipe conveying the pulp into a cellulose factory bleaching department in order to preheat the pulp to a specified temperature suitable for a subsequent bleaching stage.
  • the principle of the invention can be used also for equipment for the admixing of fluids other than steam into a second fluid, e.g. admixing of gases, such as oxygen, chlorine gas and possibly also ozone, or for admixing of a liquid, such as e.g. a pH adjusting liquid, chlorine dioxide or other treatment liquid or diluting liquid into the said second fluid, which need not necessarily be a pulp suspension.
  • an apparatus according to the invention is labelled generally with the number 1.
  • This is arranged in a pipe 2 for a pulp suspension, which, in the example as shall be described here, has a fibre content of medium consistency, MC i.e. a dry substance content of 5-20%, preferably 8-16%.
  • the conveying pipe 2 extends from an MC pump (not shown) to a treatment vessel (not shown) in a bleaching department.
  • the example shows a peroxide step.
  • the task to be carried out by means of the apparatus 1 is to preheat the pulp suspension by means of steam in the conveying pipe 2 to a temperature suitable for the bleaching process, for example about 100°C.
  • the flow rate of the pulp in the pipe 2 is about 5-15 m/s.
  • a steam injection pipe labelled 4 brings steam under pressure from a pressure source (not shown) into the apparatus 1.
  • a central, first element in the apparatus is labelled 10.
  • This first element 10 consists of a circular cylindrical, pipe-shaped part referred to as pipe body in the following.
  • the pipe body has the same internal diameter as the upstream pipe 2A to which the pipe body is joined.
  • the inside of the pipe body defined by the inner walls, forms a through-flow channel for the pulp which is being conveyed in the pipe 2.
  • a first flange 11, and a second flange 12 are provided respectively.
  • the first flange butts against a downstream wall 13 of a chamber 14 for the steam, which chamber is described in more detail in the following.
  • the other flange 12 butts against flange 16 which is located in the upstream end of the pipe body 10.
  • Flange 11 and wall 13, as well as flange 12 and flange 16 respectively are joined to each other with bolts in the conventional way.
  • Figure 2 shows that the chamber 14 extends round the rear and central parts of the pipe body 10. It is formed by the rear back end wall 13, a front, ring-shaped end wall 17 and a cylindrical casing 18.
  • the front end wall 17 is joined to both the cylindrical casing 18 and the pipe body 10 by welding. Together the back wall 13, the front wall 17 and the cylindrical casing 18 form a housing, which encloses the surrounded chamber 14.
  • a connection stud to the chamber 14 is labelled 19.
  • the steam pipe 4 is connected to the stud 19, and hence to the chamber 14, via a flanged joint, generally labelled 21.
  • the pipe body 10 has an inner diameter of, for example, 100 mm.
  • the pipe body 10 has slits 28 which extend through the wall of the pipe body 10 and which are evenly distributed round the circumference of pipe body 10.
  • each slit has a length of about 10-50 mm and a whidth of about 4-12 mm. The distance between each slit is about 5mm. Further, the slits are formed obliquely so that they form an acute angle of about 30° with the direction of the pulp flow.
  • a sleeve-shaped screen 32 bears against the pipe body 10 with a good fit.
  • the screen 32 can be displaced from a forward position, where the whole area of each slit is exposed, and forms an open passage between the chamber 14 and the inside of the pipe body 10, to a backward position, as shown in Figure 2, in which position the slits 28 are covered by screen 32.
  • the screen 32 can be moved also to a position between the completely forward position and the completely backward position to expose a desired area of each slit 28.
  • a movement member preferably a pneumatic cylinder 34 outside the apparatus 1.
  • the cylinder has a piston rod 35. This is connected via a yoke 36 to two rods 37, which extend through the end wall 17 into the chamber 14 where they are joined to the screen 32 as indicated in Figure 2.
  • Sealing rings 38 are located in grooves in the bores through the end wall 17 and are made to have a tight fit around the rods 37.
  • the movements of the piston in the pneumatic cylinder 34 and its positioning in the cylinder are suitably regulated in the manner described in our application 9703732-9, i.e. depending on the temperature which is measured in the pipe 2 downstream of apparatus 1, the measured value is sent to an IP transducer in order to adjust, in a known way, the positioning of the piston and piston rod 35 for regulation of the quantity of steam admixed, so that the temperature is maintained at a set desired value.
  • Normally medium pressure steam is used which is available at about 12 bar. Nevertheless, the use of high-pressure steam at 17-18 bar, and, in certain cases, also low-pressure steam can be envisaged.
  • the steam is injected into the pulp with a speed which is optimally high considering the pressure difference avaliable between the available steam pressure and the pressure in the through-flow channel 9.
  • downstream pipe 2B has a significantly larger diameter than the upstream pipe 2A.
  • the increase in area relative to the through-flow channel 9 should be at least about 50%. As seen in Figure 2, the increase in area can advantageously be about 400%.
  • Figure 2 shows the apparatus seen in a view from the side but from another direction than in Figure 1 i.e. from behind.
  • the downstream pipe 2B has a diameter which is approximately twice as large as the inside diameter of the through-flow channel 9. This implies, in the example given, that the diameter of the through-flow channel is 100 mm and that the downstream pipe has a diameter of 200 mm.
  • the holes/slits 28 are positioned near the rear end of the through-flow channel 9.
  • a ring-shaped connection piece 7 is located at the rear end of the pipe body and is arranged to fit closely to both the pipe body 10 and the flange 13, suitably by means of welding.
  • the distance from the front edge of the slits 28 to the rear edge of the through-flow channel 9 is less than the diameter, i.e. less than 100 mm. Due to the sudden increase in area immediately after the through-flow channel 9, turbulence is created which leads to additional admixing of the added steam, thereby ensuring that an even distribution of the heat supplied to the pulp is obtained in the downstream pipe 2B.
  • the sudden increase in area is effected preferably in a single stage, as shown in Figure 2. If desired, the increase in area can be effected in successive stages, but it is essential that the increase in area takes place within a length which is well below the diameter of the pipe 10.
  • the sudden increase in area acts as a retardation zone for the pulp flow, in which zone there is time for the distribution of the steam into the pulp to take place, and the turbulence created ensures good admixing.
  • the steam which is introduced to the pulp, penetrates into the pulp in the form of narrow, high-speed jets, which jets are diverted by the pulp flow.
  • the probability of the steam reaching the wall of the channel 2B is reduced, which would otherwise result in rapid cooling and impingement, which impingement would create noise.
  • the downstream pipe 2B is a separate unit in relation to the apparatus 1 and thus forms the pipe to the next apparatus in the process sequence.
  • this turbulence zone it is feasible for this turbulence zone to consist of a separate, delimited pipe section, or a unit integrated with the apparatus, which unit can advantageously be adapted so that it can be connected to any desired downstream pipe, which pipe generally has the same diameter as the inlet pipe 2A.
  • the fluids which are to be admixed can be fluids other than steam and a pulp suspension, whereby, in general, properties other than temperature are to be controlled by means of regulating the admixing conditions of the first fluid into the second fluid.
  • An example could be the admixing of chemicals into the pulp flow.
  • devices other than a pneumatic piston cylinder can be used for displacing the screen 32, such as, for example, an hydraulic piston cylinder or an electrical motor cooperating with a control device etc.
  • other forms of motion for the movement of the screen other than purely axial, e.g. helical, can be envisaged.
  • the apparatus 1 can be used in the opposite direction, so that the screen 32 in its completely open position is located upstream of the holes 31 and 28.
  • the screen 32 is displaced from its completely open position to a position where one series of holes is only partly covered, so that the stream of the first fluid through the holes in this series of holes is throttled, this could result in the fluid flowing through these holes giving a reduced penetration depth into the second fluid, the effect of the flow in the following downstream orientated holes is eliminated.
  • pipe-shaped body and pipes can have other cross sections than the purely circular cylindrical shown above, for example rectangular. Further, it is understood that there is the possibility of using more than one connection for introduction of the fluid. In addition, it is understood that, instead of slits as shown above, circular holes can be used. Similarly, it is understood that the orientation of the slits can be altered to positions other than what is shown in Figure 2. Moreover, it is understood that more than one row of slits can be arranged.
