Definitions
- the invention relates to a device for air and exhaust gas routing and Use of a gas guiding device according to the preamble of patent claims 1 or 9 and 10.
- a gas guiding device or an air and exhaust gas guide, is used in particular for fuel-heated heat generator needed to ensure that the for Combustion supply air as well as that required for combustion resulting exhaust gas without impairing the effectiveness of the combustion or the environment can be supplied or removed.
- roof guides are made with a relatively thick-walled exhaust pipe made of an aluminum alloy, such as AlMgSi, the dimensions for one effective operation of a heat generator that meets a heating requirement of is designed for a maximum of 30 kW, with an exhaust pipe diameter of 80 mm and a supply air pipe diameter of 130 mm with wall thicknesses of up to 2.5 mm are common.
- AlMgSi aluminum alloy
- the relatively large wall thickness of the exhaust pipe is due to a surface erosion due to corrosive components in the combustion air and exhaust gas. On this way, based on normal through the combustion air and the exhaust gas corrosion ensures an acceptable service life so that additional corrosion protection is not necessary.
- this concentric air / exhaust system acts like a heat exchanger where part of the thermal energy of the exhaust gas is released into the combustion air, the exhaust gas is continuously cooled down to the mouth.
- this system is a problem Circumstances below the dew point temperature, so that it is in the range of Mouth of the exhaust pipe to form condensation. With a cold one Outside temperature, the formation of condensation occurs increasingly. Since the Mouth area, so the end of the exhaust pipe the lowest Surface temperature, the damp exhaust gas is most likely to condense here and there is a discharge of the wet precipitation. This sits up the surrounding roof surface and leads when using conventional Roof ducts in double pipe construction made of aluminum pipes to a relative high aluminum discharge, which is optically very annoying on the roof surfaces deposits.
- This aluminum discharge consists among other things of ceramic Alumina components and is from the roof surfaces with which it is easy connects, or penetrates into them, only very lengthy or practically only mechanically to remove.
- the object of the present invention is accordingly a device for air and Develop exhaust gas routing according to DE 298 23 836, or a To provide gas guiding device, which the formation of, in particular optically disturbing, deposits on the roof duct surrounding Roof surfaces prevented, which is also inexpensive and durable as well as if necessary can be retrofitted.
- An essential basic idea of the invention is the knowledge that with Internals or surface coatings made of special materials an active Cleaning effect of the roof surface can be achieved.
- the object of the invention is therefore achieved by a device for Air and exhaust gas routing, especially for a gas-heated heat generator, with at least one exhaust gas and at least one, preferably concentrically the exhaust air pipe arranged solved, wherein at least exhaust gas and / or Surfaces of the device exposed to the weather are at least partially opposite Combustion air and / or exhaust gas are essentially inert or weak reactive, in particular ceramic and / or copper-containing material coated or are made from it.
- the task is achieved by using a ceramic and / or copper-containing material coated or produced from it, in particular an exhaust pipe, for use in an air and exhaust gas routing device and a device for air and exhaust gas routing solved.
- An important point of the invention is that the erosion effect of the exhaust gases leads to the fact that the smallest particles are released from a surface, which are then deposited together with dirt particles on the roof surface.
- the surface (s) of the gas guiding device or the device for air and exhaust gas guidance which are exposed to corrosive gases, in particular exhaust gases or oxygen-containing combustion air, are made of copper, copper particles are accordingly deposited on the roof surface.
- the copper particles do not bond to the surrounding roof surface, but are rinsed off together with the dirt for which they serve as a sink, and a further approach is prevented.
- the device for air and Exhaust gas routing continues to provide wind and weather protection in the form of at least one Gas guiding device on the spatial separation of air flows from supply air and ensures exhaust gas, at least parts of which with ceramic and / or copper-containing material coated or made from it.
- wind and Weather protection for those components of the device for air and Exhaust gas routing is one where the highest formation of condensation takes place, and which also includes atmospheric weather influences, such as Rain and snow are exposed, which on the one hand have a corrosive effect and on the other are suitable for transporting dirt onto the surrounding roof surfaces.
- At least parts of the Device in particular the wind and weather protection and the Gas guiding device (s) made from copper sheet.
- these parts also painted, sprayed or otherwise coated with copper colors be, including a copper-containing film coating within the scope of the invention falls.
- the device for air and exhaust gas routing including complete wind and weather protection for example in the form of Molded sheets can be made of copper, but also for reasons of cost can be dispensed with, which are located within a building and therefore Components of air and air largely insulated from cold temperatures Exhaust duct made from copper while outside a building existing parts of the device are preferably coated at least with copper. Depending on the requirement, it may even be sufficient if the exhaust pipe in itself, i.e. at least its inner surface and the wind and weather protection, shortly weather protection, coated with copper-containing material or from it is made, although both the durability and the aesthetic effect is improved in a full copper version.
- the copper sheet has one Wall thickness in the range of 0.1 mm to 3.0 mm, preferably in the range of 0.5 mm to 2.5 mm and particularly preferably in the range from 1.0 mm to 2.0 mm.
- Wall thicknesses of 0.1 mm are possible, for example, where copper sheet is used as a foil, which can be applied, for example, while in the area particularly aggressive exhaust gases, for example through sulfur dioxide or Chloride admixtures in the exhaust gas wall thicknesses of up to 3.0 mm are possible, albeit in the usual environment, wall thicknesses of the copper sheet in the range of 1.0 mm to 2.0 mm.
- the lower necessary wall thickness of copper pipes is advantageously in it justifies that copper is a semi-precious metal with a pronounced Passivation tendency trades while aluminum under exhaust gas conditions too a high surface removal tends.
- a surface is made of copper and / or ceramic material to enlarge the surface profiled.
- An increase in the surface can also be done by several individual pipes, a network or a honeycomb gas guiding device from one copper and / or ceramic material can be realized, such Profileing or surface enlarging agent preferably only in the Exhaust pipe, preferably at its outer end or on the weather protection are provided. This avoids that the flow resistance is unnecessary is increased.
- the advantage of a larger surface of the copper-containing parts lies in that the active cleaning effect of the copper with an increasing Surface of the same increases.
- a ceramic material that has titanium dioxide in particular.
- Such a ceramic is extremely resistant and already shows in small Layer thicknesses have a very good resistance to corrosive influences. Titanium dioxide, as a thermodynamically very stable connection, acts at this point, when it is carried out, similar to copper as an absorption germ, caused by rain can be washed off well from a roof surface.
- the Use the ceramic material to remove the surface from the exhaust pipe minimize and thus already prevents contamination of roof surfaces largely before.
- the principle active cleaning effect of titanium compounds and in particular of titanium dioxide is based on different modes of action. So in addition to the photocatalytic property of titanium dioxide the effects of hydrophilization and exploited the hydrophobization of surfaces. With a view to Dirt deposit and - according to the invention - especially with regard to a These effects have an effect on dirt removal, namely depending on the condition of the titanium dioxide a hydrophilization or a hydrophobization, together with the Photo catalysis at the same time and can support each other. The decision as to which of these effects is preferred can be made using the respective cleaning problem. This is discussed in more detail below received.
- the main influencing variable which is in a hydrophilization or in a Hydrophobization is used to create a surface with a certain defined contact angle with water.
- the cleaning effect is crucially important here whether it is hydrophobic or hydrophilic surfaces.
- At least the inside of the exhaust pipe is one Provided coating that a hydrophobization of the inner surface of the Exhaust pipe causes.
- a ceramic is provided for this purpose has amorphous titanium dioxide.
- Amorphous titanium dioxide can be provided.
- the amorphous is also preferred here Titanium dioxide integrated in a ceramic matrix.
- Coated according to the invention Surfaces which have titanium dioxide in the anatase crystal form are preferred. This are self-cleaning due to a small contact angle.
- the photoactivity is a semiconductor effect, which is preferred on anatase crystals occurs.
- the level of photoactivity can be determined by the size, the type of Formation and doping of the crystals can be influenced.
- photoactivity is photocatalysis and in the broadest sense an oxidation, in which, in particular organic substances, catalytically decomposes and becomes End products carbon dioxide and water are broken down.
- UV radiation especially long-wave UV radiation
- Titanium dioxide acts, generates OH radicals, which in turn are reactive and with, especially organic, water impurities react and oxidize them. Since this is a catalytic process, there is no consumption of Titanium dioxide instead.
- Titanium dioxide which is preferably present on the surface of the ceramic layer, is thus increased and degradation accelerated.
- An essential synergy effect between a hydrophilized surface on which water contaminants are good can roll off and the photocatalytic effect of titanium dioxide on the Surface is that a shielding effect caused by a high Dirt concentration can be caused, and the accessibility of the would prevent titanium dioxide for UV radiation, preferably from daylight is avoided.
- an additional Irradiation with ultraviolet light may be provided, however, depending on the can only take place temporarily in the respective circumstances.
- Titanium dioxide for example, be loaded with metal complexes. For example, this is then advantageous when it comes to the preferred degradation of a specific pollutant goes.
- hydrophobized with titanium dioxide or hydrophilized surfaces great advantages in the self-cleaning of Offer surfaces.
- the interaction of hydrophilized or hydrophobized and at the same time photocatalytically active surfaces can have a wide variety Eliminate cleaning problems, but at least significantly mitigate them.
- Surfaces coated according to the invention thus have clear advantages over conventional surfaces.
- a aforementioned device is suitable for self-cleaning Roof surfaces.
- Such a device is advantageous in the field of wind and Weather protection, the surface of these components, if they already exist exist or do not have to be replaced, but additionally with these Materials can be loaded. If necessary, also a replacement to think of the existing components as another advantage of The device according to the invention is that already installed air and Exhaust gas ducts with the corresponding additional inventive Components can be equipped. So can be tubular Copper pipe straps, which are with screw connections or with a quick fastener, for example, by clamping or plugging, can be easily provided Mount the area of the air pipe. Existing systems can quickly and easily can be retrofitted inexpensively without influencing the system function. Readjustments to the system are therefore unnecessary.
