Definitions

  • Adsorption cabin filters are known for use in motor vehicles for cleaning the supply air. Currently, they are already being used as standard in some vehicles. Common cabin filters consist of a particle filter, often in combination with an activated carbon filter, which is used to remove gaseous air contaminants (e.g. hydrocarbons, odors, nitrogen oxides, etc.). These adsorption cabin filters are used to remove high-boiling hydrocarbon compounds and odors from the ventilation air.
  • gaseous air contaminants e.g. hydrocarbons, odors, nitrogen oxides, etc.
  • These filters are usually installed in the supply air duct of the ventilation system.
  • the adsorber filters are usually replaced at regular intervals (e.g. at the inspection intervals).
  • Activated carbon filters are known to adsorb a number of gaseous air pollutants.
  • the molecules are attached to the surface of the activated carbon.
  • the absorption capacity of the filter therefore results from the available free inner surface of the adsorbent. The more mass of adsorbent available, the greater the amount of air pollution that can be absorbed.
  • the adsorption of air pollution is determined by the sorption equilibrium between the concentration in the air on the one hand and the loading of the adsorbent (i.e. the concentration of pollutants on the activated carbon) on the other hand.
  • a certain loading X of the adsorbent is in equilibrium with a certain concentration c of the air pollution the air.
  • the sorption equilibrium is largely influenced by temperature. Low temperatures favor the adsorption, higher temperatures disadvantage the adsorption and favor the reverse process, the desorption, in which the already adsorbed air contaminants are released again from the surface of the adsorbent and can thus get back into the air.
  • the operating conditions of the activated carbon filter are subject to very strong fluctuations, the effects of which on adsorption have so far been insufficiently considered in this application.
  • the temperatures in the vehicle are subject to very strong weather-related fluctuations. This affects both seasonal fluctuations and fluctuations depending on the time of day. Daytime fluctuations are particularly pronounced in the warm season. While the temperature can drop to low values at night, temperatures of up to 80 ° C can be reached in the stationary vehicle during the day in strong sunlight.
  • a further limitation of the adsorber filters results from their limited loading capacity. This is limited for the following reasons: • The use of adsorbent in the form of a bed would offer a high adsorption capacity, but such a bed shows a large pressure loss in the flow. In the present application, the use of a bed is ruled out because of the too high required power of the ventilation blower
  • Fiber material coated with activated carbon is therefore often used. However, the amount of adsorbent that can be applied is low. As a result, the loading capacity of these activated carbon filters is also low
  • the filters are replaced at certain intervals (e.g. during vehicle inspections)
  • the usual long replacement intervals result in progressive loading of the activated carbon filter.
  • the loading capacity of the adsorber filter can be exceeded for certain substances. As a result, these substances are no longer or at least not completely absorbed by the adsorber filter high boiling point and in the case of odorous substances, the adsorption causes at least some cleaning at the usual exchange intervals
  • the loading of the activated carbon filter also depends on the concentration of air pollution in the inlet air. For frequent journeys in heavily used environments (eg tunnels or city centers), it may therefore be necessary to change the adsorber filter more often
  • the activated carbon filters may only be loaded up to a low load. A further, higher load is possible under certain conditions, but desorption can then take place under certain conditions (eg at higher temperatures in the vehicle)
  • the activated carbon filter will be partially loaded. After a longer operating time, due to the sorption balance and whose temperature dependence the effect depends on the ambient conditions
  • Air pollutants that have been adsorbed at low temperatures can, for example (due to the temperature-dependent sorption equilibrium) desorb at higher temperatures and thus get back into the indoor air
  • the following example may explain this in the morning at low temperatures when driving in city traffic (higher concentration of air pollutants) the air pollutants are adsorbed on the activated carbon filter.
  • the activated carbon filter can clean the air pollutants down to low concentrations
  • the interior of the vehicle can reach temperatures of up to 80 ° C.
  • similar temperatures can also occur in the activated carbon filter.At these temperatures, the sorption equilibrium is much less favorable, and desorption is favored (especially when the activated carbon filter is loaded)
  • Already adsorbed air contaminants are released again from the surface of the activated carbon filter and thus get into the indoor air.
  • the concentrate Under unfavorable conditions, the concentrate can The air pollution in the snow room is significantly higher than if there were no activated carbon filter at all. With increasing operating time and increasing loading of the activated carbon filter, this process will occur more frequently
  • a further disadvantageous process can occur in the case of particularly high atmospheric humidity.
  • the fine pores of the activated carbon filter required for the adsorption can be completely occupied by water molecules (so-called capillary condensation).
  • the fine pores are no longer available for the adsorption of the air contaminants Grouting
  • previous versions show that previous adsorption filters - especially with advanced loading - can rather be regarded as smoothing filters. At high concentration peaks the pollutants are absorbed by the filter, at low concentrations and especially at high temperatures the already adsorbed pollutants can be released into the air again become
  • the object of the invention is to develop an arrangement with which the activated carbon filter can also operate reliably over a long period of time. According to the invention, this object is achieved as follows

  • the desorption can then proceed as follows after parking the vehicle After parking the vehicle, a small air flow is sucked in from the interior by the existing blower (which, however, changes the direction of rotation for desorption). This air flow is then heated in the heat exchanger by the cooling water and then passed through the adsorber
  • the temperature of the cooling water of max. Approx. 110 ° C (with a slight overpressure in the cooling system) is sufficient for desorption.In many cases, the cooling water reaches its highest temperature immediately after the engine is switched off due to the lack of travel cooling, which in practical operation is caused by switching on the Radiator fan becomes clear
  • a further advantage is that - especially in warm, humid weather - some of the air moisture condenses in the air cooler. Air with a lower water content is therefore passed through the adsorber, thereby reducing the accumulation of water in the pores of the adsorber

  • a heat exchanger is arranged after the air cooler, but before the adsorber, the air can be partially heated again after the moisture has condensed out, which reduces the relative humidity of the air.

  • heat is also transferred directly to the adsorbent.
  • not all of the heat has to be transferred through the desorption air Design of a smaller desorption air flow This means that an even smaller blower output is sufficient (see Fig. 17 20)

  • desorption according to the above Executions can also be carried out while driving. In this case, however, the vehicle ventilation and the vehicle heating are not available during this desorption time.
  • Another variant is the use of two separate adsorbents. This corresponds to the use of clocked adsorbers or of rotor adsorbers in process engineering applications. The desorption of one adsorber can take place while the other adsorber is in operation.
  • the disadvantage is the considerably greater equipment outlay

If an adsorber is integrated in each of the two ventilation ducts, separate adsorption and desorption can be implemented in a relatively simple manner Although there is limited functionality of the respective ventilation duct during the desorption of one of the adsorbers, the additional outlay in terms of equipment is very low.

  • Another advantage of the solution according to the invention is the lower required mass of adsorbent due to the desorption at shorter intervals.
