Definitions

  • the present invention relates to an improved method of making paper on machine, as well as the paper machine adapted to the implementation of such a method.
  • the invention uses the technique of dispersed air flotation, making it possible to rid the water used in the manufacture of paper of surfactants.
  • these substances tend to stabilize any air bubble introduced into the head circuits, especially when the dough is highly sheared as in a binder, a pump, .... This therefore requires the availability of deaerators usually placed just before the headbox.
  • the surfactants remain within the suspension or process water and accumulate in the top circuits.
  • the document DE-A-199 14 779 discloses a method of making paper on a machine comprising, in the wet part, a white water flotation step, as well as a paper machine comprising, in its wet part, a white water flotation cell.
  • the invention therefore relates to a method for producing paper on a machine comprising in the wet part at least one step of separating the surfactant substances present in the white water by dispersed air flotation.
  • surfactant substances means chemical compounds which, introduced into a liquid, lower the surface tension, which has the effect of increasing the wetting properties.
  • fatty acids or nonionic surfactants can for example be fatty acids or nonionic surfactants. These substances are found in large quantities in the process water when the pulp used for the manufacture of the paper is recycled pulp. Indeed, in addition to the substances added voluntarily during deinking, other surfactants are "salted out” by the recovered papers (surfactants put into the formulation of printing inks, in the formulation of the layers applied to the surface of the paper for manufacturing magazine papers) and also released by mechanical pulp fibers when they are obtained (defibration, refining) or bleaching.
  • the surface-active substances have no potential beneficial effect, even if present in a small amount.
  • the object of the invention is therefore the total elimination of the surface-active substances present in the waters used for papermaking, after separation.
  • the step of separating the surfactant substances is carried out using the technique of dispersed air flotation.
  • This technique consists in separating the surfactants from the water containing them, dragging them to the surface by the insufflation, within the liquid mass, of air bubbles having a diameter that may range from a few hundred microns a few millimeters. This results in a flotation foam rich in isolated surfactant substances. This foam is then separated from the treated liquid, for example by suction or overflow.
  • Another contribution of the invention has been to determine the most judicious places of the papermaking process, where the dispersed air flotation treatment has to be carried out.
  • the treatment is carried out on a stream with a low content of suspended solids.
  • the surfactant removal process must concentrate the rich surfactant-rich rejection as much as possible.
  • the dispersed air flotation treatment is carried out on all or part of the white water.
  • the step of separating surfactants by dispersed air flotation is carried out directly on the filtration water, from the web or table forming paper, before their recirculation and recycling.
  • a second possibility, even more efficient, is to implement this air flotation dispersed on the water of the fiber recuperator, at the machine head, at the level of the white water circuit of the paper machine.
  • the recovery of the fibers can be carried out either with the aid of a disk filter or with a dissolved air flotation cell.
  • the water from this fiber recuperator is therefore depleted of suspended solids, which makes it possible to limit the losses in solids.
  • the dispersed air flotation generates a so-called flotation foam in which the surface-active substances are trapped in concentrated form.
  • these foams are intended to be eliminated after recovery, typically by overflow or by suction.
  • a method according to the invention provides for the evacuation of this flotation foam directly in a purification plant.
  • the flotation foam is pretreated with ozone, which facilitates the degradation of the surfactants.
  • Another possibility is to introduce this flow in the middle of the sludge dewatering table, to drain the surfactants into the sludge.
  • the invention relates to a paper machine adapted to the implementation of the method described above.
  • a paper machine according to the invention is therefore characterized by the presence in its wet part of at least one cell adapted to dispersed air flotation allowing the separation of surfactants present in white water.
  • such a cell is designed to have contact time between air bubbles and water to be treated, sufficiently long.
  • all surfactants even with slow adsorption kinetics, have time to migrate to the air / water air bubble interfaces.
  • the rate of air introduced into the cell must be large enough for the adsorption surface of the surfactants to be sufficient. In order to minimize water losses, several stages are necessary. One of the ways of minimizing water losses is also to have a cell with a sufficient foam thickness to dry the concentrated foam in surfactants.
  • the dispersed air flotation cell as described above, is advantageously positioned at the level of the white water circuit, in particular at the level of the filtration water coming from the paper forming fabric, before it is put back into circulation and recycled.
  • the flotation cell is located on the clarified water circuit from the fiber recuperator, so as to minimize material losses.
  • the paper machine according to the invention is advantageously provided with a system for recovering foams generated by the dispersed air flotation cell.
  • a system for recovering foams generated by the dispersed air flotation cell According to a first system, it is a connection between the flotation cell and a purification plant, preferably via an ozone treatment unit.
  • the flotation cell is connected to a sludge dewatering table.
  • the present invention relates to any type of paper machines. More particularly targeted by the present invention, paper machines or processes consuming small amounts of fresh water, or even operating in a closed circuit. It is in these conditions that the waters are the most loaded with surfactants.
  • the invention is also very useful and efficient when the paper is formed from recycled (especially de-inked) or mechanical pasta (wood pulp, ).
  • a third application also seems particularly suitable: during the manufacture of coated papers from virgin pastes, the process can be implemented on the thickening waters, generated during the recycling of the manufacturing breakages to be thickened.
  • the figure 1 illustrates a paper machine according to the invention for the implementation of the advantageous paper manufacturing method as described.
  • the paper machine according to the invention is conventionally equipped with a headbox (1) providing a homogeneous distribution of the paste over the entire width of the paper forming table (2), a press section ( 3) to remove water by pressing and a dryer (4) to remove the residual water by evaporation before winding the roll paper (5).
  • the filtration water beneath the forming fabric is recovered for recycling and to dilute the pulp in the head circuits, before the hydrocyclones (6) and the machine head files (7) for removing contaminants with a higher density. to 1 on the one hand and the contaminants of size greater than 150 - 200 microns on the other hand.
  • the filtration water under the forming fabric is either recycled directly without any treatment, or clarified by the clarifier, in this case a dissolved air flotation cell (8).
  • the flotation treatment of water can then be carried out on all or part of the stream of white water recovered under the formation web (9A ), or all or part of the flow of water free of suspended matter, at the outlet of the clarifier (9B).
