Definitions
- the invention relates to an infrared radiator, in detail according to the independent claim.
- Generic infrared emitters are used in dry arrangements, which are used for heat treatment, such as the drying of a material web, such as paper, tissue or board web. These drying arrangements are part of machines for producing and / or treating such material webs. Also glass fleeces would be conceivable.
- a preferred field of application is the drying of running paper, tissue or board webs in paper mills, for example, seen in the running direction of the web behind coating devices.
- Known infrared radiators have, for example, a plurality of rods, which are preferably arranged in a plane, that is coplanar. However, it is also known to arrange the bars in a plurality of mutually parallel planes which are spaced from a burner plate.
- the rods of generic infrared radiators are made of ceramic.
- Such infrared radiators can be gas-powered. You are then assigned a burner. This is operated with a gas-air mixture. In this case, the burner has a burner plate which is charged with the gas-air mixture. The gas-air mixture is ignited, for example with an electrode. The resulting flame heats the bars.
- the latter serve as incandescent bodies. Because they give off the heat in the form of infrared radiation to the material web.
- rods are as incandescent also highly heat-resistant metals, for example in the form of grids or porous ceramics known.
- infrared radiators are used as surface radiators.
- a plurality of such infrared emitters is arranged side by side along the width and / or longitudinal extent of the material web to be treated.
- the required Number of spotlights selected.
- a disadvantage of the infrared emitters known from the prior art is that their radiation efficiency is not optimal for every application.
- the known gas-powered infrared emitters as a result of the combustion of the gas-air mixture in part produce a very high proportion of nitrogen oxides (NO x ) and carbon monoxide (CO).
- previous incandescent bodies made of ceramic parts, such as rods are susceptible to the fact that, in the event of breakage, the entire rod crashes onto the material web and can cause damage to the machine.
- the present invention relates to such, initially mentioned objects.
- the invention is based on the object to provide an infrared emitter, which is improved over the prior art.
- the radiation efficiency as well as the exhaust gas behavior of the infrared emitter should be improved in terms of nitrogen oxides and carbon monoxide.
- it is intended to prevent parts of it from falling down onto the material web and the resulting damage and stoppages of the machine.
- radiation efficiency is understood to mean the ratio of the power supplied to the infrared radiator and of the radiated power, in this case in the form of infrared radiation.
- An infrared radiator according to the present invention dries, for example, during normal operation (operating state) of the drying arrangement or the Machine a material web. This is the condition in which the gas-air mixture burns within the infrared radiator and simultaneously heats the (at least one) incandescent body. The combustion can take place in the space bounded jointly by the burner plate and by the at least one incandescent body - then called the combustion chamber.
- An incandescent body in the sense of the present invention is thus the article which itself flows through the gas-air mixture or its combustion products and is heated as a result of the combustion of the gas-air mixture. It is that part of the infra-red radiator that glows as a result of its heating. By annealing is meant the emission of radiation visible to the human eye.
- the incandescent body may be that part of the infrared emitter which is arranged behind the burner plate in the flow direction of the gas-air mixture. The former can be far from the burner plate or in contact with it. The incandescent body is thus ignited by the flames, e.g. arise on the side facing the incandescent burner plate as a result of the combustion process, heated.
- the incandescent body comprises all those elements which, together with the burner plate, delimit the combustion chamber of the infrared emitter.
- the at least one incandescent body can represent the outermost surface of the infrared emitter, which directly, ie directly opposite, the material web to be treated. In such a case, the incandescent body is then arranged between the burner plate and the material web.
- Sheets are basically made from a variety of linear shapes such as threads. In the case of such fabrics, the linear formations thus form or limit openings of the fabric. It could also be said that the fabric is made in the manner of a net or grid and the openings are the meshes of the net or grid. These openings can - seen in plan view of such a sheet - different geometric shapes, such as polygons, eg rhombuses, squares or Accept hexagons. The areal extent of such openings is measured in the aforementioned plan view in length and width. The openings taken together represent the cavity of the incandescent body and are flowed or flowed through during operation of the infrared radiator of the gas-air mixture or its combustion products.
- a fabric is understood to be a fabric woven from warp and weft threads. Warp and weft threads cross each other.
- the fabric may comprise a single or a plurality of different, preferably a plurality of different thread systems in their mechanical properties. But it is also conceivable that such fabrics are used, in which the threads of warp and weft are made of the same material. Threads that serve as warp and weft threads touch each other at the crossing points.
- a knit or knit can be knitwear.
- the term knitted fabric is understood to mean those fabrics in which a loop formed by means of a thread is looped into another loop. Knitted fabrics can be obtained, for example, by knitting or crocheting, whereby each course of stitches is formed of a single thread stitch by stitch.
- Knitted fabrics consist of one or more thread systems. A noose engages in the loop of the preceding course. In the case of the knitted fabric, on the other hand, at least two thread systems are used and the stitches of one course are formed simultaneously. The loops define here the crossing points at which the threads touch each other.
- braid is understood to mean entanglement or interlocking between directly adjacent threads.
- the threads can be designed spirally.
- the self-supporting fabric looks as if the individual threads were produced by interlacing the spirals. So, as if a thread were screwed lengthwise into a neighboring thread, so that both spirals snuggle into each other and touch at the crossing points. The Longitudinal axes of the spirals are then parallel to each other in this fabric.
- fabrics according to the present invention have repeating, preferably regular, patterns formed by the yarns.
- nonwovens are a confused, random array of fibers that are tangled together or held together by a binder. Nonwovens are therefore not covered by the term fabrics according to the present invention, so that a nonwoven expressly does not constitute a fabric.
- the advantage of the use of regular pattern-forming fabrics is that over the entire extent of the sheet uniformly the same combustion and thus a consistent exhaust behavior takes place when the sheet is used as an incandescent body.
- the term thread in the context of the invention means a line-shaped, long and thin structure. The thread is much longer than thick, ie the diameter of the thread can be between 1 and 10 mm and thread lengths of up to 300 mm.
- the thread can be made of a rigid material, ie a material of comparatively high bending stiffness, such as a ceramic.
- bending stiffness means the product of the modulus of elasticity with the corresponding area moment of inertia.
- modulus of elasticity is meant a material characteristic value from the material technology which describes the relationship between stress and strain in the deformation of a solid body with linear-elastic behavior.
- An initially described long and thin thread is rigid in the context of the invention, if he does not change his impressed outer contour, as soon as it is taken out of the fabric under at least partial dissolution of the fabric.
- Bend fluff threads can be made by the aforementioned methods such as weaving or knitting, since the thread is yielding and its outer contour is freely malleable during the process.
- bending-resistant threads can not be produced according to such methods without altering or destroying their outer contours. Therefore, such fabrics are made according to the invention by means of prototypes. This means that the entire fabric - and not just the individual threads individually - is made primitive. Preferably, it is therefore monolithic and therefore one-piece.
- An articulated connection according to the invention makes it possible for the individual threads to move relative to one another at the intersection points relative to one another in the produced, self-supporting fabric.
- the joints are therefore formed at the intersection points of the threads with each other of the threads themselves. These are preferably hinges at the joints.
- a fibrous web ie a scrim or Gewirre of fibers such as cellulose fibers, plastic fibers, glass fibers, carbon fibers, additives, additives or the like understood.
- the material web may be formed, for example, as a paper, cardboard or tissue web. It may essentially comprise cellulose fibers, with small amounts of other fibers or else additives and additives being present. Depending on the application, this is left to the skilled person. If according to the invention of the flow direction of the gas-air mixture is mentioned, then this is the main flow direction of the particles of the gas-air mixture meant.
- This direction corresponds for example to a perpendicular to the largest surface of the burner plate of the infrared emitter, which is traversed by the gas-air mixture (inflow surface of the burner plate).
- the inflow surface can thus be at least one boundary side, ie the surface which is spanned by the spatial length and width of the burner plate.
- the boundary side can be spanned by the longitudinal and width edges (the inflow surface) of the burner plate.
- the burner plate at its largest boundary surface, which faces the gas supply or the premixing chamber, be flowed through by the gas-air mixture. If the burner plate is designed in the manner of a cuboid, the inflow surface is at least one side surface of the cuboid.
- the inflow surface of the incandescent body is also a side surface (boundary surface) of the cuboid, which represents a flat surface. Therefore, the above definition for the incandescent body and its Anström requirements applies analogously.
- the incandescent body is also flown along this inflow surface with the gas-air mixture or its combustion products.
- the flow direction of the gas-air mixture may also be perpendicular to the largest boundary surface or inflow surface.
- the direction of flow of the gas-air mixture through the incandescent body may be the same as that through the burner plate.
- the inflow surface of the incandescent body may be identical to the inflow surface of the burner plate, so that both are coextensive. So it can be that common area that mantle and burnplate share when they are directly adjacent to each other. If, in accordance with the present invention, it is mentioned that one element directly adjoins the other, then it is meant that both elements have no other Means - and preferably also free from a distance - in direct contact with each other.
- ceramic it is understood to mean a technical ceramic. Examples of this are e.g. Silicon carbide, molybdenum silicide. In principle, high-temperature-resistant metals such as FeCrAI compounds or heat conductor alloys would also be suitable as material for incandescent bodies.
- the incandescent body is produced from a plurality of layers arranged one above the other, it is understood that several layers of flat structures arranged one behind the other in the flow direction of the gas-air mixture can also be provided. This means that the layers are stacked in the flow direction of the gas-air mixture seen one above the other. This brings the advantage according to the invention that the exhaust gas values can be further improved.
- At least in sections means at least a part of the mantle. When it is said that one element at least partially surrounds another, it is meant to partially or completely surround or encase the corresponding element.
- pre-formed is meant that the element in question was produced by a manufacturing process in which a solid body is produced from an informal material. Examples include casting, sintering, 3D printing.
- the invention relates to a drying arrangement for heat treatment of a material web comprising an infrared dryer, which has a plurality of preferably arranged in the width and / or longitudinal direction of the material web to be treated infrared emitter according to the invention.
- a drying arrangement may comprise at least one air dryer to hot air and / or a To direct combustion product of the gas-air mixture of the plurality of infrared emitters on the material web to be treated.
- the at least one air dryer and the at least one infrared dryer seen in the direction of the material web to be treated can be arranged one behind the other, wherein preferably the at least one infrared dryer can be seen upstream of the at least one air dryer in the direction of the material web to be treated.
- the invention also relates to the incandescent body of claim 1 per se and such with the features of the subclaims.
- the invention relates to a machine for producing and / or treating a material web, preferably a paper machine, comprising at least one infrared radiator according to the invention or such a dry arrangement.
- a material web preferably a paper machine
- the invention will be described in more detail below with reference to the drawings without limiting the generality.
- FIG. 1 show a schematic, partially cut and not to scale representation of an embodiment of an infrared emitter; a possible embodiments of an inventive mantle in a spatial representation;
- FIG. 3 is a highly schematic representation of a drying arrangement in a three-dimensional view according to an embodiment.
- Fig. 1 shows an exemplary embodiment of the invention in a schematic, partially sectional view through a plane which is perpendicular to the web and parallel to the direction (indicated by the arrow) this runs.
- an infrared radiator 1 which may be part of a drying arrangement 9, is shown.
- the infrared radiator 1 is in normal operation at a distance from the web 8, for example, arranged above this.
- the latter has, for example, a rear wall and a plurality of side walls.
- the rear wall is located on the side facing away from the material web 8 (rear side) of the infrared radiator.
- a fuel such as gas and air (flammable combustible gas-air mixture) can get into a mixing chamber 3, provided.
- the corresponding supply lines outside the infrared radiator 1 are not shown in detail.
- the mixing chamber 3 is presently limited on the one hand by a gas-permeable burner plate 4 and on the other hand by the housing 1 1 .1, here the rear wall.
- the gas-air mixture flows to the burner plate 4 at an inflow surface which corresponds to the back of the infrared radiator 1 and passes through the gas-permeable burner plate 4 for its combustion. From there it flows into a combustion chamber 5.
- the latter is presently limited or formed together by the burner plate 4 and an incandescent body 6.
- the gas-permeable burner plate 4 separates, as it were, the mixing chamber 3 from the combustion chamber 5. In the latter ignites the gas-air mixture. The released heat heats the incandescent body 6 until it begins to glow. As a result, this emits infrared rays in the direction of the web 8 to be dried.
- Both the burner plate 4 and the incandescent body 6 here have a plate or cuboid outer contour. In principle, a different outer contour would be conceivable.
- the inflow surface of the incandescent body 6 corresponds to the inflow surface of the burner plate 4. In other words, the two inflow surfaces are identical in area. They correspond here to the clear width of the housing 1 1 .1, in which both the burner plate 4 and the incandescent body 6 are housed.
- the infrared radiator 1 faces with its incandescent body 6 of the material web 8, in the illustrated case so that the incandescent body 6 extends parallel to this. However, this does not necessarily have to be the case.
- the infrared radiator 1 can also extend at an angle to this.
- the burner plate 4 and the incandescent body 6 are connected in series.
- the incandescent body 6 is arranged downstream of the burner plate 4.
- the incandescent body 6 is designed in the manner of a regular, gas-permeable grid. This grid can be formed by at least one sheet. This is made of a variety of threads that limit openings of the grid. This means that the gas-air mixture passing through the burner plate 4 can also flow through all the openings of the incandescent body 6 (simultaneously).
- the incandescent body 6 is arranged in the flow direction of the gas-air mixture or its combustion products seen at a distance from the burner plate 4. That is, the combustion chamber 5 is formed by the space bounded together by the burner plate 4 and the incandescent body 6. Burner plate 4 and incandescent body 6 are arranged with respect to their inflow surfaces or boundary sides parallel to each other.
- the incandescent body 6 directly adjoins the burner plate 4. This means that both are arranged without spacing and preferably parallel to one another. Regardless of the illustrated embodiment, it would be conceivable in principle, e.g. several layers of an incandescent body 6, more precisely to provide a plurality of layers of fabrics, which could be arranged spaced from the burner plate 4 in the flow direction of the gas-air mixture or the resulting combustion products.
- FIG. 2 shows a possible embodiment of the incandescent body 6 according to the invention as a planar structure in a spatial representation.
- the latter is made of a variety of threads 15.
- the fabric is exemplified as a spiral braid.
- the threads 15 are entwined in the manner of spirals.
- the longitudinal center axes of the threads 15 extend over the entire spatial extension of the self-adjusting sheet parallel to each other.
- Directly adjacent threads 15 are connected to each other, that their spirals are screwed together.
- the threads 15 are each articulated to each other at the common crossing points.
- a part of a thread 15 should break, so it is held by the adjacent threads 15 at the crossing points. The probability that parts of the broken thread fall on the web 8 is thereby significantly minimized. Breakage can occur when the thread 15 is made of a ceramic.
- the incandescent body 16 could also be made in the manner of a fabric.
- two threads directly adjacent to one another which are in the form of weft threads, weave the same weaving path through the warp threads perpendicular to threads acting as warp threads.
- the radiation efficiency can be increased considerably. This is achieved in that increases due to the selected outer contour, the surface for the combustion of the gas-air mixture, which manifests itself in a higher energy consumption of the combustion products of the gas-air mixture. The proportion of nitrogen oxides and carbon monoxide in the combustion products can be reduced thereby.
- FIG. 3 shows a possible embodiment of a dry arrangement 11 according to the invention.
- This can be part of a machine for producing or treating a material web.
- the drying arrangement 1 1 is presently arranged in the running direction of the material web 8 behind a coating or binder part of the machine, not shown. Within this lot, a coating color or a binder is applied to the web 8. As a result of the order takes The Matenalbahn 8 moisture and must therefore be dried or the binder must be cured. This takes place in the drying arrangement 1 1.
- the drying arrangement 1 1 comprises one or, as shown here, a plurality of infrared driers 12, each of which has a plurality of infrared radiators 1, which are preferably arranged parallel to the material web 8 and serve as area radiators.
- the drying arrangement 1 1 also has a plurality of air dryers 13.
- Each such an infrared dryer 12 and an air dryer 13 are referred to as a combination dryer 14.
- combination dryer 14 In the present case four in the direction of the web to be dried web 8 successively arranged combination dryer 14 are provided. The latter are arranged directly adjacent to each other here.
- the drying arrangement 1 1 in each case seen in the running direction of the material web 8 through the drying arrangement 1 1 between an infrared dryer 12 of a first combination dryer 14 in the running direction and between an infrared dryer 12 of a further combination dryer 14 immediately following in the running direction Combination dryer 14 associated air dryer 13 arranged.
- the material web 8 is dried alternately along the drying arrangement 11 by means of heat radiation, then by means of convection, again by means of thermal radiation and so on.
- the infrared dryer 12 of a respective combination dryer 14 can be designed as a gas-heated infrared dryer according to the invention.
- the infrared dryer 12 may comprise one or more infrared emitters 1 according to the invention (see FIGS. 1 a and 1 b).
