Definitions

the invention relates to a process for the production of cellulose.
the invention further relates to the cellulose industry, and more particularly to the recovery of cellulose from vegetable collus containing raw materials.
the invention may be used for the recovery of cellulose intended for petroleum processing, cotton wool production and the paper industry.
the Alkaliuf gleich is carried out at 120 - 130 ° C within 1 hour.
the liquor contains a surfactant.
the mass is then washed with a 1.5-fold amount of the clarified water, crushed and finely cleaned in a hydrocyclone with clarified water.
the twice bleaching with NaOCl solution is performed.
the temperature is 90 ° C
the pH is 9 - 11.5, the duration is 1 hour.
the following steps are carried out: washing with softened water, acidification with H 2 SO 4 solution at 15-40 ° C within 1 hour, repeated washing with softened water, spin-drying and air drying.
the temperature is 130 - 140 ° C
the pressure is 3-4 atm
the duration is 180 - 210 min.
the following steps are carried out: washing, bleaching with sodium hypochlorite in an acidic solution, spin-drying, loosening and drying ( RU 2078163 ).
a prototype is the process for obtaining cellulose from cellulosic raw materials by simultaneous loosening and purification steps and further successive steps; Washing and comminution of raw materials, soaking, thermomechanical-chemical processing, washing, bleaching, washing, ejection and drying.
the raw materials are allowed to mature in an alkaline solution ( RU 2007115321 ).
the WO 2005/045126 describes a process for treating pulp fluids by heating in the presence of an alkaline earth metal oxide in a reactor at a temperature above 650 ° C.
the invention is based on the object to provide an efficient and cost-effective method for the production of cellulose from cellulose-containing raw materials available.
the raw materials used are herbaceous plants, in particular with a high content of shives, the woody inner part and lignin, with a high deposit duration on the fields and in storage rooms.
Two parallel coupled shafts are installed in a heated chamber. Alternate auger and crushing cam segments are mounted on the shafts.
thermo-mechanical-chemical processing is carried out before washing in a twin-screw apparatus, on the shafts of which alternating conveyor and brake screw segments are mounted.
alternating auger, crushing cam and brake screw segments are mounted on the shafts.
cellulose-containing raw materials are herbaceous plants, such as fiber flax, L. subsp. intermedium, oil flax, green flax, oilseed rape, miscanthus, clover, alfalfa, caster, Jerusalem artichoke, galega, Heracleum sosnowskyi, corn, etc., in various degrees of maturity, with high content of woody interior and lignin and with a large deposit duration, for example, in the fields and used in storage rooms.
herbaceous plants such as fiber flax, L. subsp. intermedium, oil flax, green flax, oilseed rape, miscanthus, clover, alfalfa, caster, Jerusalem artichoke, galega, Heracleum sosnowskyi, corn, etc.
the twin screw apparatus comprises a working chamber with a dense wall, feed and drainage nozzles. Within the working chamber two parallel coupled shafts are installed. Attachments of various purpose are mounted on the shafts: screw conveyor, crushing cam and brake screw segments. The worm segments are mounted alternately on the shafts. (Proof of the USSR no. 884715, 1981 ).
the working chamber is favorably equipped with resistance heating elements.
the heating elements can be laid around the outside of the wall. All heating elements can be connected to a controlled external power source.
a thermosensor can be connected to the control input of this power source.
cellulose-containing raw materials from herbaceous plants are pre-soaked in an alkali solution.
the solution can be prepared with circulating water having a NaOH content of 10 to 60 g / l and a surfactant content of 0.2 to 0.8 g / l.
the soaking can take place for 15-60 minutes at 90-100 ° C.
the hydraulic modulus (the ratio of the solid / liquid phases) can be 1: (1 0 + 20).
the heated pulp with 5 - 10% of the cellulosic raw materials is then conveniently in the on z. B. 80 - heated to 100 ° C twin screw apparatus.
alternating auger, crushing cam and possibly Bremsschneokensegmente are mounted on the shafts of the twin screw apparatus alternating auger, crushing cam and possibly Bremsschneokensegmente are mounted.
the screw segments can be displaced relative to one another such that a screw channel is formed.
the turns of the screw segments can have the same diameter, the same direction and a fixed gear per screw segment.
the winding path of each next screw segment may be smaller than the winding path of the previous screw segment.
the distance between the turns of the screw segments and the inner wall of the working chamber may be 0.5 - 10 mm.
the direction of the screw channel of the shredding cam segments and the direction of the screw flights may coincide.
Preferably 10-16 screw conveyor segments and 5-20 crushing cam segments are used.
the processed pulp is in the z. B. 85 - 105 ° C heated twin screw apparatus transported.
Alternating conveyor and brake screw segments are mounted on the shafts of the apparatus.
the screw conveyor segments may have 2 (or more) turns more than brake screw segments.
thermomechanical-chamical processing is performed before washing.
the processed pulp is conveyed to the twin screw apparatus heated to, for example, 90-110 ° C.
crushing cam and possibly brake screw segments are mounted on the shafts of the apparatus.
10 to 16 screw conveyor segments preferably 7 to 20 crushing cam segments and preferably 4 to 10 brake screw segments are used.
the pulp may be washed in softened water to remove the alkali radicals from the cellulosic mass.
the washing is conveniently carried out in two stages.
the mass is allowed in containers filled with water within z. B. 20 - 30 minutes at z. B. 80 - 90 ° C and within z. B. 20 - 30 minutes at z. B. 40 - 50 ° C lie.
the hydraulic module can be 1: (10 + 20) at each stage.
the bleaching of the flat cellulose may be carried out in a hydrogen peroxide solution having a concentration of e.g. B. 5 - 10 g / l at conveniently 85 - 95 ° C within z. B. 90 minutes.
the hydraulic module can be 1: (10 + 20).
the cellulose can be further washed with softened water, for example, as well as after Alkaliuf gleich.
the centrifuging can be carried out in centrifuges of type AG or AOG up to z. B. 40 - 50% moisture.
the cellulose can be dried, for example, with combustion gases at 140-160 ° C in a Vibrotrockner.
the dried cellulose can be carried in a cyclone for air separation and on to the packaging.
Two parallel coupled shafts are installed in a heated chamber. On the shafts are mounted alternating feed cutting and crushing cam segments.
thermo-mechanical-chemical processing is carried out before washing in a twin-screw apparatus, on the shafts of which alternating conveyor and brake screw segments are mounted.
