Definitions

  • the present invention relates to the problems of pulp filtration at paper and more particularly pulp from pulping old papers.
  • filters comprising a rotor and a stator, one of two, hereinafter referred to as sieves fulfilling the function of filtering with holes such as slots or holes, the other below called decolator, fulfilling the declogging function with means for generating pressure pulsations to prevent clogging holes.
  • the sieve can therefore be fixed or rotating and, conversely, the decolator is rotating with a fixed sieve and fixed with a rotating sieve. Of the more the liquid can either flow through the sieve from the outside to the inside (towards the axis), so-called centripetal operation, either from the inside to the outside, said centrifugal operation.
  • the dough arrives at one end of the cylindrical sieve, flows in the space between the cylindrical sieve and the decolator, and spring at the other end.
  • the decolator turns, it tends to drive the dough with him in rotation. If the decolator is fixed, it is the filter that tends to cause the dough in rotation. In both cases, as the effect of declogging by the pulsations of pressure caused by the decolator is directly related to the speed difference between the decolator and the dough, the dough progresses towards the end of the sieve, less unclogging is effective and this while the sieve is more likely to seal.
  • the present invention relates to a filtration apparatus of the type comprising a cylindrical sieve and a decolator equipped with blades that produce pressure fluctuations to fight against the clogging of said sieve, the latter being in at least two parts of substantially equal diameter from each other by means intended to break the component of the velocity of the liquid, which is parallel to the surface of the sieve and to create turbulence, characterized in that said means are baffles formed on the one hand by cavities formed in an annular ring of the sieve disposed between said sieve parts and secondly by a deflector annular carried by the decolator in front of each crown of the sieve bearing the cavities, so that the majority of the liquid flow is forced to cross the cavities.
  • the present invention also provides a method of using this apparatus for the treatment of paper pulp according to which each part of the apparatus of filtration includes an output of accepted products and each annular ring of the sieve optionally has a dilution inlet the filtration apparatus further comprising an input and an output of the rejects, and according to which by playing on the settings of the accepted product exits, the release of the rejects and the arrivals dilution of the pipes reduces the rotation speed of the decolator so that it is as low as possible in order to save energy, while maintaining a low discharge rate.
  • the present invention also aims at the implementation of the above means described for filtering pulp.
  • the sieve is constituted, as has been described in patent EP 0 707 109 by a stack of circles 1 with U section, pressed against each other by means of two end crowns 2 and 3 assembled to each other by tie rods 4 which make it possible to establish a prestressing.
  • the bases of the U are provided with holes (whether they are slots or holes).
  • the dough arrives in the filter by its end to the left of the figure (on the side of the crown 2) and emerges by its opposite end (on the side of the 3) circulating in the space 6 located between the decolator 5 and the sieve as indicated by the arrow f1.
  • a slowdown zone is created for the speed at which the dough is driven.
  • an annular partition 21 perpendicular to the filter axis and carried by the rotor 5.
  • Fluidization is understood to mean a stirred and floc-free state of the dough which favors the flow in the openings, holes or slots of the sieve.
  • the sieve is divided into two parts; a first part in upstream of the crown of cavities C and a second part downstream, these two parts being separated from each other by the crown of cavities C.
  • the baffle 20/21 is disposed in the middle of the sieve; in Figure 3 it is arranged near the end, that is to say where the effects of clogging are the most important because of the thickening of the dough.
  • Figure 4 combines the provisions of Figures 1 and 3.
  • turbulence is also created by fins 10 fixed to the decolator and fins 11 fixed on the screen.
  • These fins 10 and 11 may be radial or inclined and may have inclinations in the opposite direction.
  • fins 10/11 are such that they fit into each other.
  • FIG. 6 represents a centripetal filter that uses the means of FIG. 1. The same elements bear the same references.
  • the sieve 1 is inside the decolator 5.
  • the dough arrives at the end of the sieve and circulates in the space 6 located between the sieve 1 and the decolator 5.
  • the U-section circles are replaced by partitions 20, parallel to the axis of the cylinder, and the decolator 5 comprises a annular partition 21.
  • the paste is deflected by the annular partition 21 and hits the partitions 20.
  • Figures 7 to 17 show an alternative embodiment of the apparatus implementing the method according to the present invention.
  • FIG. 7 represents a cylindrical sieve 30 which consists of bars 31 arranged vertically next to each other with a slight clearance (included between 0.05 mm and 1 mm) and fixed on horizontal rings 32, 33, 34, 35, 36 and 37.
  • FIG. 8 shows the rotor 40 which is placed inside the sieve of the FIG. 7.
  • This rotor is a cylinder which comprises three annular rings 41, 42, and 43. In the areas between the ring rings are arranged blades 45, commonly referred to as "foils" in the pulp industry.
  • the function of the foils 45 is to cause pulsations of pressure / depression which tend to prevent clogging of the sieve.
  • the rings 41 to 43 are arranged on the rotor so as to be opposite crowns 33, 34 and 35.
  • the annular rings 41, 42 and 43 define four zones of the rotor 40.
  • the shape, number and inclination of the blades or foils 45 may vary from one area to another.
  • Figure 9 shows the screen of Figure 7 seen from the inside.
  • crowns 33, 34 and 35 are hollow so as to define cavities C.
  • the cavities C are not made as in the case of Figures 1 to 6 where the sieve was constituted by U.
  • the rings 33, 34, 35 are constituted by a ring comprising a multitude of parallelepiped cavities having practically the same shape as the cavities C of Figures 1 to 6.
  • Some cavities C crowns 33 and / or 34 further comprise orifices which are connected to dilution inlet pipes 50.
  • Figures 10 and 11 are detail views, on a larger scale of the figure 9.
  • Figure 12 illustrates a variant according to which, instead of having parallelepiped cavities C cylindrical cavities or blind holes are available Some may be connected to conduits 50.
  • the annular ring of the rotor 41 (42,43) which cooperates with the ring 33 (34, 35) is arranged to be substantially at the middle of the cavities C or cylindrical holes D.
  • Arrow F illustrates how dough from the area below crowns 33, 41 is forced into a cavity C or D, this cavity and the crown 41 forming a baffle that significantly slows the speed of the dough.
  • FIG. 14 illustrates another variant embodiment in which the same elements bear the same references.
  • the screen 30 is fixed and placed outside the rotor 40 which 45.
  • the ring 41 of the rotor 40 is in front of the ring 33 of the sieve 30 so that the cavities C of said ring 33 form with the annular ring 41 a series of baffles.
  • a pipe 50 which is a water pipe.
  • the filter element constituted by the screen 30 and the rotor 40 is thus divided in three areas X, Y and Z from the bottom.
  • the pulp to be purified arrives at Q at the base of the device.
  • Zone X has an output 60 for the so-called "accepted” products, that is to say who passed through the sieve 30; zone Y has an output 61 for Accepted products and Zone Z an exit 62 for accepted products.
  • thickening causes a decrease in the efficiency of the declogging which must be compensated for example by a higher speed and therefore a higher energy consumption.
  • the introduction of water into ducts 50 which open into certain cavities C or D of the crown 34 and the ring 33 makes it possible to counter this thickening and thus makes it possible to reduce the rotor speed and thus save energy.
  • the apparatus comprises a cover 63, an output R for the rejects.
  • the speed of the rotor 40 can be adjusted according to the pressure differential between the entry Q in the apparatus and at least one of the pressures prevailing in the outlet ducts of accepted products 60, 61, 62.
  • the sieve can be made in many ways either by stacking rings to U-section of Figures 1 to 6, either by stacking grids obtained by juxtaposition of bars of Figures 12 and 13, or by stacking the sheets perforated cylindrical holes or slits of Figure 15.
  • they may be constituted by plates 70, in the mass of which were hollowed with circular milling grooves 71, the slots are then machined with circular saws.
  • the rotor 40 being divided into as many portions as the sieve 30 can at each portion of the rotor have different blades 45 as to their number, their form, and their inclination.
  • edges of the cavities C or D are exactly at the same level as that of the inner wall of the sieve 30.
