Definitions
- the invention relates to a device comprising a steam blower box to act on a passing paper, cardboard, tissue or other fibrous web as well as the provision and refinement of steam or a steam / air mixture connected to a steam supply line.
- Such steam boxes combined with a separate steam refinement are known, for example, from DE102018116125 A1 and are used in particular in the press section -DE102018116125 A1- and in the former of paper machines.
- the web temperature can be increased and the viscosity of the water contained therein can be reduced.
- improved drainage or drying can be achieved, and the physical properties of the fibrous web can advantageously be changed.
- the steam To apply steam to the paper web, the steam must have a constant low pressure of typically greater than 4 bar in order to enable optimal condensation and optimal heat transfer on the surface of the fibrous web.
- the steam In the steam distribution line, the steam is transported from the boiler house or power plant to the paper machine, typically greater than 6 bar.
- the expansion and steam conditioning takes place in a separate steam station, in which the steam is cooled by adding water and the pressure is evenly regulated via various longer pipes and valves.
- the steam box itself is currently operated at a pressure of less than 2 bar. Examples of this are the Valmet “IQ Steam Profiler” system and Voith steam processing station for the steam box.
- Such steam conditioning is also shown schematically in FIG.
- the disadvantage of this type of steam conditioning is that the steam station requires its own installation space and is usually supplied with its own condensate system must become. The often limited installation space in existing systems can make it difficult to retrofit a steam blower box economically.
- a device for applying water vapor to a moving paper, cardboard, tissue or other fibrous web comprising a steam blower box with a steam distribution device, several separate zones with valves and nozzles directed towards the fibrous web, which are connected to a steam supply line that delivers steam at a pressure of greater than 4 bar, typically greater than 6 bar, is connected.
- another device for reducing the steam pressure comprising a steam valve in the supply line, a metering device with a nozzle for introducing cooling water and at least one condition measurement of the expanded steam.
- the functions of the steam box and the steam station are implemented in one structural unit.
- devices according to one aspect of the invention are therefore very compact and require little installation space.
- a pressure vessel for storing the conditioned steam can be dispensed with, since the conditioned steam is applied to the fiber web directly after conditioning. Intermediate storage is therefore not necessary.
- the commissioning engineer can commission the steam blower box and the conditioning at the same time. This saves a lot of time compared to the separate commissioning of the two individual units, also because the complete device can be pre-assembled.
- the water dosed for cooling and relaxation should be salt-free and free from insoluble particles in order to reduce wear on the nozzles in the dosing device.
- condensate or boiler feed water can be used here.
- the metering device can contain one or more atomizing nozzles which are arranged in a steam line between the automatic valve and the steam blower box and are suitable for atomizing the metered water in drops with a diameter of less than 0.5 mm.
- the water introduced into the metering device should itself pass into the vapor phase for cooling and relaxation of the steam. It is therefore advantageous to introduce the water in small drops via an atomizing nozzle, because the higher specific surface favors the heat transfer and thus the phase change. Even smaller droplet diameters, for example 0.4 mm, 0.3 mm or 0.2 mm or smaller, can therefore also be advantageous since these further promote the phase change. Depending on the amount of steam used, it can also be advantageous to attach several nozzles to the steam line in order to achieve an even distribution of the water introduced.
- the metering device has one or more atomizing two-phase nozzles, which are arranged in a steam line between the automatic valve and the steam blower box, suitable for atomizing the metered water even more finely by adding steam or air, in particular to a drop size smaller than 0.2 mm.
- the addition of air or steam at the nozzle can bring in additional energy for a finer atomization of the liquid via the expansion of the compressed gas and / or the higher flow rate. If steam is used for this, the thermal energy also enters the water to be atomized, which also supports a rapid phase change of the liquid droplets.
- Such atomizing nozzles are available on the market and are published, for example, in WO201 0 / 054798A1.
- an effective section is advantageous so that the metered water can pass uniformly and completely into the vapor phase; this effective section should be at least 1 m long, preferably at least 2 meters.
- the effective distance is advantageous in order to regulate the pressure in front of the steam blower box evenly to the target value.
- At least one state measurement after the metering device preferably after the effective section, is advantageous.
- the steam temperature, the pressure and / or the volume flow can be used as a status measurement measured in order to regulate the steam valve depending on the amount of steam released by the steam box.
- the steam box is usually built over the entire paper web, so a stable construction is particularly important.
- the effective path described can make a direct contribution to stability. This is preferably done by a design with a round cross-section or a rectangular design, with a cross-sectional ratio of height to width greater than 1, preferably greater than 2, the height being defined as perpendicular to gravity.
- the stability can also be improved if the material is designed according to the effective section, preferably with a wall thickness greater than 1 mm and made of a steel material.
- the object is achieved in that at least one of the devices described is used to condition the steam in such a way that it can advantageously be applied to the paper web with the steam blower box. It is advantageous to operate the steam blower box at an overpressure of less than 2 bar, in particular at an overpressure of 0.5 to 1.5 bar, since otherwise the flow rate and temperatures are in an unfavorable range for ideal condensation of the steam on the material web enable.
- a uniform steam pressure is particularly advantageous; this can be achieved by using the effective section and precise and fast regulation of the steam valve.
- it is advantageous to introduce water for cooling with an excess pressure of 20 to 500 mbar.
- It is also advantageous to atomize the introduced water into small droplets, as this enables a faster phase change / evaporation over the larger specific surface. If steam or air is additionally introduced into the atomizing nozzles, the droplets can be atomized more finely or torn apart via higher flow velocities.
- FIG 1 shows an apparatus according to one aspect of the invention
- Figure 2 shows a device according to a further aspect of the invention
- FIG 3 shows a device according to the prior art
- FIG. 1 shows the device in a schematic longitudinal section, with several independent zones for steaming being shown in the area of the steam blower box 5, each of which includes a zone valve 9 and an application nozzle 8.
- Steam at a high pressure of more than 4 barg, typically 6 barg, is fed to the device through the steam supply line 1; the amount is regulated by the steam valve 2.
- the steam is then cooled and relaxed with a metering device 3 by adding water or a water / gas mixture, the state measurement 4 being used to regulate the metered water and the amount of steam added via the steam valve 2.
- the evenly pressure-regulated and cooled steam is then passed via the distributor device 7 to the zone valves.
- FIG. 2 differs from that in FIG. 1 in that an additional effective path 10 is shown, and the state measurement 4 is arranged accordingly after the effective path.
- the active section can be integrated directly into the steam blower box 5 and form a structural unit with it. This also gives the possibility of structurally supporting the steam blower box 5 with the active section 10 and reducing the heat losses through the structural unit with the steam distribution device 7.
- FIG. 3 shows the steam blower box 5 designed according to the prior art with a separate steam station 11. The steam station is separated from the steam blower box by another Steam line 17 which directs the steam in a cooled and pressure-regulated state to the steam blower box.
- the prior art usually requires a separate condensate system 12 and a plurality of condition measurements 15 in order to condition the steam with the cooling water nozzles 13.
- the steam station 11 separated by the steam line 17 also usually requires further safety valves 14 and a separate active section 16 in order to achieve the steam conditioning evenly and safely.
- the design according to the prior art is also disadvantageous, since large surfaces can also lead to heat losses or at least require more thermal insulation
