Definitions
- the present invention relates to a device for wetting fiber material, in particular wood, wood chips and waste paper.
- TMP thermo-mechanical pulp
- the fiber's strength increases with increasing fiber length and such fibers are suitable for producing high-grade papers, the greatest possible moisture and elasticity of the fibers is desired during refining.
- the invention has for its object to provide devices with the help of the wetting of wood chips or waste paper in bale shape is simple and effective.
- a device for humidifying fiber material in the alternating pressure process with an air and vapor-tight housing and a vacuum line, wherein in the vacuum line, a first directional control valve is provided, achieved in that the housing at least one closable opening for loading and unloading of the housing and a vent line, and that in the vent line, a third directional control valve is provided.
- the principle is: the moister the woodchips blown into the pulp digester, the higher the bulk density and thus the throughput of the pulp digester.
- the device according to the invention can be started significantly earlier with the filling of the digester with cooking liquor, since the wood chips do not float when pumping the cooking liquor when its moisture is sufficiently large.
- roundwood lumber
- the highest possible moisture content of the wood is crucial in order to keep the proportion of splinters and fines low.
- the pieces of wood of up to 2 meters in length are pressed against a large, rough grinding stone with high pressure and thereby defibered and crushed. The more moist the roundwood is in this processing, the more elastic, softer and smoother the fiber composite in the entire piece of wood and each of its individual fibers and the smaller the proportion of splinters and fines. Even with such pieces of wood can be saved by the use of a device according to the invention considerable amounts of energy and time.
- the ventilation line according to the invention makes it possible to carry out the change between negative pressure and ambient pressure or an overpressure more quickly and thereby further increase the effectiveness of humidification.
- the device can be operated continuously in batch mode or in two or more openings, so that the efficiency and the throughput rate of the device according to the invention are also markedly increased by this improved method sequence.
- the wetting liquid in the liquid (liquid) or gaseous (vapor) form, or in a combination of both are used.
- the wetting liquid may be water, solvent, a single chemical or a chemical mixture.
- the wetting liquids may also be in vapor form.
- wetting liquids when used and used in the present invention may have a temperature from very cold to the boiling point.
- the wetting agents used may be coloring, hydrophobic, hydrophilic, bleaching, resin and lignin decomposing, impregnating, preserving and / or surface tension lowering or enhancing, inorganic or organic in nature.
- the housing has a closable first opening for loading and a closable second opening for discharging the housing, because this can further increase the effectiveness and the throughput of fiber material to be moistened.
- the at least one opening can be closed with a door, a flap, a slide, a valve, a screw plug of a lock and / or a SiphonverSliver.
- Doors and flaps are particularly suitable for introducing large pieces of fibrous material to be moistened, such as a bale of pressed waste paper, while a slider or a valve is particularly suitable when the fibrous material is in small pieces and is to be supplied continuously.
- An advantage of the door, flap, slide and valve is that the opening can be closed defined and thereby always controlled and reproducible pressure conditions prevail in the interior of the housing. Due to the pressure-tight or gas-tight Closing the opening, the pressure change rate or the pressure change rate is increased, which has a positive effect on the effectiveness of humidification.
- the advantage of a plug screw is that it can continuously or clocked fiber material, which is already mixed with the liquid, such as water or cooking liquor, can promote into the housing and at the same time causes an airtight and vapor-tight closure of the housing opening.
- the plug screw is therefore particularly suitable for continuous or quasi-continuous operation of the system and can be coupled for example with a valve or a slider.
- a supply line for the medium with which the fiber material is moistened is provided in a further advantageous embodiment of the invention.
- a control valve is further provided, so that the amount of medium in the housing can be controlled according to a predetermined setpoint.
- a pressure line may be provided with a second directional control valve. This makes it possible not only to make a pressure reduction, but also make an increase in pressure within the housing in alternation with this pressure reduction. By increasing the amplitude between the maximum pressure and the minimum pressure, the moistening and penetration of the liquid into the fiber material to be moistened is further intensified.
- the pressure line is advantageously in communication with a compressed air generator and / or a pressure vessel. This makes it possible to build the pressure quickly and at the same time, when a pressure vessel is used, the compressed air generator can be made smaller and run continuously.
- a conveying device which is preferably designed as a screw conveyor, conveyor belt and / or as a chain conveyor.
- the conveyor can also be omitted if the device is made sufficiently inclined.
- FIG. 1 shows a circuit diagram of a first exemplary embodiment of a device according to the invention
- FIG. 2 shows circuit diagrams of further exemplary embodiments of the device according to the invention with two screw worms and a screw conveyor,
- Figure 4 shows an embodiment of a device according to the invention, which combines the functions of a pulper and a device according to the invention for the moistening of fiber material.
- a housing is provided with the reference numeral 1.
- the illustrated housing 1 has a cuboid geometry.
- a side wall of the housing 1 is formed as a door 2 and can be closed by means of a closure 3 air and vapor-tight.
- the door 2 is opened and it can, for example, wood chips or a bale, not shown, are transported with waste paper in the housing 1. Subsequently, the door 2 is closed and locked, so that the interior of the housing is sealed air and vapor-tight from the environment.
- the housing interior can be traveled with a pallet truck or other transport device, so that one or more bales of waste paper, which are located for example on a Euro pallet, can be easily and quickly brought into the housing interior with the aid of a lift truck.
- the reference numeral 4 denotes a supply line.
- a control valve In the supply line is a control valve. 5
- the liquid with which the fiber material is intended to be moistened can be introduced into the interior of the housing 1 in liquid and / or vaporous form in accordance with the requirements.
- water is used for humidification.
- upstream of the control valve, a conveyor, not shown, such as a pump, and / or a storage tank is located.
- the reference numeral 6 denotes a vacuum line.
- This vacuum line 6 has a first directional control valve 7, which is usually designed as a switchable 2/2-way valve, a vacuum tank 19 and a vacuum generator 20.
- the vacuum tank 19 is only optional. If such a vacuum tank 19 is present, the vacuum generator 20 can be relatively small in size and continuously suck air or steam from the container 19. If then the directional control valve 7 is opened, a pressure reduction can be made very quickly and effectively in the interior of the housing 1, although the vacuum generator 20 is dimensioned relatively small. It goes without saying that the volume of the vacuum container 19 and the volume of the housing 1 as well as the power of the vacuum generator 20 must be coordinated.
- the reference numeral 8 denotes a pressure line, in which a second 2/2-way valve 9 is integrated.
- This pressure line 8 is connected to a compressor 15 and a pressure vessel 16. Again, the pressure vessel 16 is used to increase the life of the compressor 15 and at the same time to reduce the required power of the compressor 15.
- the pressure line 8 is only required if after the lowering of the pressure in the interior of the housing 1, an overpressure to be generated.
- air, steam or a liquid can be conducted into the housing 1 via the pressure line 8.
- the reference numeral 11 denotes a ventilation line.
- a third directional control valve 12 is provided in this ventilation line 11.
- the device according to the invention works as follows:
- the fiber material to be moistened is conveyed into the housing 1. Subsequently, the door 2 is closed air-tight and vapor-tight.
- the first directional control valve 7, the second directional control valve 9 and the third directional control valve 12 are initially closed.
- Through the supply line 4 is at least partially open control valve 5 for moistening the paper of the paper located in the housing 1 (not shown) required medium in the vapor and / or liquid state transported into the interior of the housing 1.
- control valve 5 is closed and the first directional control valve 7 is opened quickly.
- the interior of the housing 1 is connected to the vacuum tank 19 and there is a pressure equalization between the two containers.
- the pressure inside the housing 1 abruptly drops to values between 0.9 bar and 0.1 bar, preferably to values between 0.7 bar and 0.3 bar.
- the first directional control valve 7 is closed and immediately thereafter, the third directional control valve 12 is opened, so that a pressure equalization between the environment and the interior of the housing can take place.
- the "sudden" compensation is of particular importance in this case, it must be as fast as the vacuum collapsed Fibers and cavities want to revert back to their original form.
- the third directional control valve 12 can be closed again after a few seconds and the second directional control valve 9 can be opened. Between the closing of the third directional valve 12 and the opening of the second directional control valve 9 can take a few seconds or even less than a second time. Since the pressure line 8 is connected to the pressure vessel 16, immediately after the opening of the second directional control valve 9, a pressure equalization between the pressure vessel 16 and the interior of the housing 1 takes place. As a result, the pressure inside the enclosure rises to levels above ambient. Preference is given to overpressures between 0.1 bar and 1 bar.
- the second directional control valve 9 When the desired overpressure inside the housing 1 has been reached, the second directional control valve 9 is closed and this overpressure is maintained for several seconds, for example 5 seconds, but preferably less than two seconds. Now the cycle begins again. So that the overpressure does not have to be reduced by the vacuum generator 20, the third directional control valve 12 can be briefly opened beforehand, so that the overpressure via the ventilation pressure equalization line 11 is reduced.
- FIG. 2.1 shows a second exemplary embodiment of a device according to the invention, which is preferably operated continuously but can also be used in batches.
- the housing 1 is formed as a cylindrical tube.
- a first opening 21 is provided at the left in Figure 2.1 end of the housing 1.

- a valve 27 is arranged, which can be actuated via an actuator 29, for example in the form of a pneumatic cylinder.
- the first closing valve 27 is shown in the closed position. Dashed the position of the open valve 27 is shown.
- the feed line 4 is branched such that a branch of the feed line 4 opens directly into the housing 1 via the control valve 5.1, while further branches 4.1 and 4.2 open into the feed hopper 25 or the plug screw 23.
- a second control valve 5.2 is provided, which also serves to control the amount of liquid flowing into the device according to the invention.
- the screw plug 23 is similar in construction to a conventional screw conveyor. The main difference is that the pitch of the screw conveyor decreases in the conveying direction, so that in addition to the conveying movement still a compression of the conveyed material is made.
- the plug screw can also be tapered in addition, however.
- the moisturizing fiber material preferably in the form of wood chips, together with, for example, given water and then promoted by the first plug screw 23 in the direction of the housing 1.
- a compression of the conveyed wood chips takes place, so that a pressure-tight plug forms in the first plug screw 23.
- a seal of the housing interior is achieved by the environment.
- the sealing of the opening 21 by the propene screw 23 and the of her compacted wood chips enough.
- the closing valve 27 may be provided.
- the closing valve 27 is opened at the end of the second plug screw 35, or if the pressure of the plug screw 35 is greater than the pressure of the actuator 29, the moistened wood chips and any existing excess water can fall down from the device according to the invention.
- the exemplary embodiment of a device according to the invention described with reference to FIG. 2 can optionally be operated continuously or batchwise, since woodchips are conveyed by the first plug screw 23 into the housing 1 at any time and the moistened wood chips with the aid of the second Grafting screw 35 can be conveyed out of the housing 1.
- the first opening 21 and the second opening 33 of the housing 1 are closed by a siphon 36.
- the siphon closures 36 is water or other suitable barrier liquid.
- the level of the barrier liquid is adjusted via the supply lines 37 and the control valve 38 so that no direct connection between the atmosphere in the interior of the housing 1 and the ambient air is present.
- a conveyor belt 40 is guided, which leads (not shown) to be humidified fiber material into the interior of the housing 1.
- the pulleys belonging to the conveyor belt 40 have been provided with the reference numeral 34.
- tines 42 are arranged, which allow the transport of the fiber material in the vertical direction and against gravity.
- the housing 1 open the supply line 4, the vacuum line 6 and the pressure line 8. The inflow or outflow is controlled by these lines by means of the valves 5, 7 and 9 in the manner already described above.
- Fig. 3.2 shows another embodiment of a device according to the invention with siphon closure and a conveyor belt, here a tube-chain conveyor.
- Fig. 4 illustrates another embodiment of a fibrous material wetting apparatus according to the present invention particularly suitable for wetting single or multiple waste paper or pulp bales, paper in sheets, and split paper rolls.
- This device can be made by modifying a conventional pulper and is also suitable for retrofitting such pulpers.
- the pulper, as well as the hood mounted on top must be adapted to the pressure conditions present invention.
- the fiber material is introduced by means of a conveyor 42 through the open opening 21 into the housing 1. Thereafter, a slider 48 is shut down and thereby the opening 21 is closed.
- the control valve 5 of the supply line 4 is opened and wetting liquid, in particular water, added to the desired level. When the level is reached, the control valve 5 is closed again.
- a motor 46 is turned on thereby causing a rotor 44 to rotate.
- a thorough mixing of the waste paper or pulp bales located in the housing 1 and the wetting liquid takes place.
- Non-fibrous material eg foils, wires
- a large discharge opening not shown
- a gripping crane device through openings in the pulper hood, not shown.
- the paper fibers Due to the very short wetting times and thus very short dissolution and residence time of the waste paper in the pulper according to this device, the paper fibers can be very quickly dissolved by plastic films or other coatings and pumped through the perforated plate 50. This non-fiber materials can be removed from the pulper housing 1 in significantly larger pieces. In addition, the today usual Nachsortier effort of the fiber material that has been pumped through the perforated plate 50 can thereby be greatly reduced.
