Example Embodiment

[0050] Example 1

[0051] Dissolve or decompose the following components in 900ml of water:

[0052] -80-100, preferably 90g bentonite

[0053] -30-60, preferably 45g activated carbon

[0054] -20-50, preferably 35g methylimidazole ethyl sulfate,

[0055] -2-8, preferably 5g N-(L-α-aspartyl)-L-phenylalanine methyl ester

[0056] - 4-8, preferably 6 g of sodium alginate.

[0057] The solvent or dispersion thus produced is applied to the carrier body 21, preferably by dipping the carrier body into the solvent. The carrier thus pretreated was then introduced into a 2% aqueous calcium chloride solvent. The insoluble alginate is produced by the incorporation of calcium (or another suitable multivalent metal ion), which is used to gel or solidify the filter layer. Next dry in a stream of air. In a next step, an ionic liquid is additionally applied to the fixed filter layer. For this purpose, the carrier is immersed in 1-ethyl-2-methylimidazolium ethyl sulfate or sprayed wi...

Example Embodiment

[0058] Example 2

[0059] As in Example 1, the solvents or mixtures described there were produced and applied to the surface of the carrier. The filter layer is fixed in a second step, however, directly by immersing the support body in 1-ethyl-2-methylimidazolium ethyl sulfate and subsequently drying it in a stream of air. In this variant of the invention, the fixation or gelling of the filter layer and the application of the ionic liquid are thus carried out in a single step.

[0060] figure 2 The air conditioning system of a passenger aircraft is schematically shown. The passenger cabin 4 and cockpit 5 of the aircraft are supplied with air by supply pipes 6 . The air is a mixture of thermostated fresh air and filtered recirculated cabin air.

[0061] Fresh air is provided by a so-called bleed air branch from the compressors of one or more propellers 7 . The main part of the bleed air (temperature typically 215°C - 260°C) which is heated due to compression is sent to ...

Abstract

The invention relates to a filter for binding constituents of a gas stream, comprising a supporting member and a filter layer that is applied to the surfaces of the supporting member. According to the invention, the filter layer comprises the following components: a) a component for physically adsorbing constituents; b) a component for chemically adsorbing constituents; c) a component for dissolving oil constituents, said component containing ionic liquids.

Description

technical field [0001] The invention relates to a filter for a component of a combined gas stream, having a carrier body and a filter layer applied to the surface of the carrier body. The object of the invention is also a method for producing such a filter, the use of such a filter for filtering breathing air in a vehicle, in particular an aircraft, and a device equipped with a filter according to the present invention. Invention of the filter plane. Background technique [0002] Many means of transport, especially airplanes and eg high-speed trains, are usually constructed pressure-tight and artificially ventilated. Airplanes have pressurized cabins in which the cabin pressure above the outside air pressure is regulated at travel flight altitudes. [0003] The air supply of the pressurized cabin is usually achieved not only by circulating and purifying the cabin air but also by mixing with externally supplied fresh air. Since the outside air at travel flight altitudes is...
