Definitions

  • the invention relates to a filter device which is arranged or can be arranged in a channel of an at least one gaseous medium generating and / or leading unit and is adapted to at least partially filter residues conducted in the gaseous medium out of the gaseous medium flowing through the channel.
  • Such filter devices are basically known from the prior art. These are intended to filter out residues, for example combustion residues or other particles carried in the gaseous medium, from the gaseous medium which are generated, for example, by the gaseous medium generating and / or leading aggregate during its operation.
  • the units described above find numerous applications, for example as internal combustion engines in vehicles, ships and aircraft, wherein the filter device is used to filter from the gaseous medium, in particular a generated exhaust stream or in a supply air, residues, in particular combustion residues.
  • gaseous medium is not restrictive to understand, but it can ultimately be considered as gaseous medium, each gas or fluid which has been generated by a corresponding aggregate.
  • hot gas refers to gas that is heated or heated relative to the environment.
  • Such filter devices are also known for heaters, especially with a solid fuel operable small fire systems, known, for example in the form of pellet stoves.
  • a filter material in the channel, so that the above-described particles can be separated or filtered from the exhaust stream.
  • filter devices absorb residues, for example combustion residues, over their lifetimes, so that the filter devices, in particular their filter material, saturate or become clogged with the filtrate used during the use.
  • residues for example combustion residues
  • filter devices in particular their filter material
  • the filter devices saturate or become clogged with the filtrate used during the use.
  • the flow of the gaseous medium through the filter device is reduced, and on the other hand the ability of the filter material to absorb further residues or to filter out of the (gaseous) medium flow decreases.
  • the service life of a known filter device exceeded, in particular a defined capacity of residues no longer (sufficiently) given the filter material must be cleaned or replaced to restore the effect of the filter device.
  • the disposal or reprocessing of the filter material is complex and expensive and thus presents a certain challenge.
  • the temperature of the gaseous medium in front of the filter device or the area of the gaseous medium-carrying device (aggregate) in front of the filter device also increases. This can thus be damaging to various components upstream of the filter device, for example sensors or measuring probes of the unit, or even destroy the components.
  • the invention is therefore based on the object to provide an improved filter device, in particular a filter device in which the disposal of the filtrate or the filter material or the maintenance of the filter properties and the safe operation of the unit is improved over the life.
  • the invention is based on the finding that the filter device is flammable above a defined temperature assumed by the gaseous medium, wherein the filter device has at least one ignition means whose ignition temperature is greater than or equal to the defined temperature, wherein the ignition means is formed when the ignition temperature is exceeded to inflame the filter device. Accordingly, it is provided that when the ignition temperature is exceeded, that is to say when the ignition means is heated to or above the ignition temperature, the filter device is ignited by the ignition means.
  • the filter device is thus designed to burn independently above the defined temperature.
  • the filter device thus ensures that an independent burning of the filter device takes place at a temperature rise at the filter device over the defined temperature or over the ignition temperature.
  • the gaseous medium thus assumes the defined temperature or exceeds it due to the operation of the unit and / or due to a reduced flow through the filter device.
  • the operation of the unit is thus not limited to normal operation. In case of failure, if, as described above, a temperature increase of or occurs on the filter device, the defined temperature is also assumed by the gaseous medium.
  • Such a temperature increase can thus be generated by the fact that due to a filter device added or saturated to a defined degree, the flow of the gaseous medium through the filter device is reduced. Due to the slower flow through the, in particular hot, gaseous medium, the medium can heat the filter device stronger. By burning the filter device when the defined temperature is exceeded, it is ensured that the gaseous medium does not accumulate on the filter device, so that the formation of dangerous, in particular toxic and / or explosive gas mixtures can be prevented.
  • the filter device After the filter device has been burned, the gaseous medium is no longer accumulated, so that it does not reach other areas on other flow paths, in which the gaseous medium can damage material or personnel. Furthermore, it prevents the filter device upstream components, such as probes or sensors are damaged by a temperature increase due to the reduced flow.
  • the filter device is thus "sacrificed" to prevent the previously described negative effects.
  • the defined temperature is selected such that the filter device burns before the effects of significant use, ie in particular before damage to a component occurs and / or the gaseous medium is no longer defined by the channel.
  • the defined temperature is thus preferably chosen such that it lies below a critical temperature for at least one component.
  • a monitoring of the pressure is possible, so that the filter device burns before a defined pressure in the channel is exceeded.
  • the defined temperature is thus determined as a function of a pressure prevailing or to be expected in the duct.
  • any channel of an aggregate through which the gaseous medium can be passed can be understood as the channel.
  • the filter device can also be arranged at an opening, so that the gaseous medium is passed through the filter device when it flows through the opening.
  • Such an opening is also understood in the context of this application as a channel.
  • it is not necessary that the channel is closed.
  • a gas flow conducting surface also meets the requirements for a "channel".
  • the channel is closed, for example in the form of a flue, chimney or the like.
  • Gaseous medium does not necessarily mean that gas is generated.
  • the gaseous medium may be generated, for example, by a combustion process or a chemical process. It is also possible that the aggregate promotes the gaseous medium, for example by overpressure or negative pressure.
  • the filter device is designed as a filter device for a heater, in particular a small fire system, wherein the filter device is arranged or arranged in a combustion chamber or a channel of the heater and is adapted to at least one phase of a Burning of burning in the combustion chamber fuel combustion residues at least partially from the flowing through the combustion chamber and / or the channel gaseous medium (supply air or exhaust air, especially secondary air or tertiary air) to filter.

  • the term "inflame” or “flash point” is thus understood that above a defined, in particular material-dependent, temperature burning of the relevant material is basically possible, below the temperature, a burning is not possible.
  • a further heat source is required, which is in thermal contact with the material and at least initiates the combustion process above the defined temperature.

  • the ignition means in this case has an ignition temperature which is greater than or equal to the defined temperature.
  • ignition temperature is understood to mean a temperature above which the material having the corresponding ignition temperature is ignited, that is to say it begins to burn.
  • no direct action by a heat source (such as contact with a flame) is required for such ignition, so the material on the associated ignition temperature, as is the case with flames, but it is sufficient, the corresponding material on the ignition temperature to heat, so that a combustion process of the ignition means is initialized.
  • a combustion process is also understood to mean the destruction of the filter device without the formation of flames.
  • the filter device can therefore for example also be decomposed or burned or smolder or melt. Accordingly, the filter device is destroyed upon reaching or exceeding the defined temperature or upon reaching the ignition temperature, the ignition device is thus designed to destroy the filter device upon reaching the ignition temperature.
  • the filter device accordingly has an ignition means which is ignited during the combustion process when the ignition temperature of the ignition means is exceeded, that is to say it begins to burn.
  • the ignited ignition means is then adapted to ignite the filter device, since the ignition temperature is greater than or equal to the defined temperature above which the filter device is flammable. In other words, in a combustion process, the temperature in the heater will rise steadily and thereby exceed the defined temperature and the ignition temperature, so that the flammable filter device is burned by the ignited ignition or the combustion process is initiated by the ignition.
  • phase In a combustion process, various phases are passed through, which can be classified, for example, into five phases, as explained below.
  • the classification of the individual phases is merely an example.
  • a first phase of the combustion process the fuel is dried.
  • hydrocarbons are expelled from the fuel, followed by a first incomplete combustion in a third phase, since no optimal oxygen to carbon ratio has yet been established.
  • a complete combustion of the fuel takes place, so that air supplied via the air can react completely with the released fuel gases.
  • the combustion of the fuel takes place without the formation of flames (embers). Based on the above-described classification of the combustion process in the individual phases, takes place in phases 4 and 5, the largest release of heat energy through the heater. Since combustion of the fuel takes place largely in these phases, the combustion residues emitted in these phases are at a significantly lower level than in phases 1 to 3.
  • phase 3 in phases 1 to 3, especially during the phase of incomplete combustion (phase 3) there is an increased emission of combustion residues, so that there combustion residues must be filtered from the exhaust stream to environmental influences, especially emissions, for example by soot particles.
  • phases 4 and 5 in which either complete combustion or residual fuming of the fuel takes place, the filtering of the gaseous media stream can largely be dispensed with, since unburnt hydrocarbons are no longer formed, but only carbon dioxide is produced .

Until the phases described are reached, the temperature in the heater, in particular in an area in which the filter device is arranged, is still below the defined temperature, so that the filter device is not inflammable. Thus, it is ensured that the filter device is flammable only when the defined temperature is exceeded, so that they are not burned before the corresponding phases of the combustion process, in which no or significantly less combustion residues are generated, and thus removed from the media stream. It is also ensured that the ignition means is ignited only when reaching or above the defined temperature, since the ignition temperature of the ignition means is greater than or equal to the defined temperature.
  • the temperature in a combustion process (at the beginning of a combustion process) is steadily increased until the defined temperature has been exceeded and the ignition temperature of the ignition means has been reached or exceeded. Accordingly, the ignition means is ignited and thus sets the filter device on fire so that the ignition means and the filter device burn, in particular fall into the combustion chamber and are thus burned together with the fuel. Disposal of the filter material and the pollutant filtrate is thus unnecessary, since it burns together with the fuel in the combustion chamber.
