Definitions
- the present invention relates to a filter material with adsorbing properties, consisting of a carrier layer and an adsorbing layer connected to the carrier layer.
- EP-A-0 340 542 adsorption filter which consists of a support frame with a coating of adsorber particles.
- the adsorber particles fixed to the support frame clean undesirable substances through gases or liquids that pass through the filter.
- Such cleaning processes always represent a balance between the stationary and the moving phase.
- the known adsorption filters represent a sufficient means to effect cleaning.
- High-boiling substances such as water and phenol can be easily and effectively removed from gas mixtures using conventional adsorption filters.
- Such conventional adsorption filters have adsorption particles made of activated carbon, for example.
- DE-A-195 13 658 describes an odor filter for vacuum cleaners which consists of an air-permeable carrier which contains synthetically produced spherical activated carbon.
- DE-A-196 7 755 A method for producing a filter material is known, in which thermally granular adsorbents are fixed on a metal foil coated with polyolefin, the preferred adsorbent being activated carbon.
- the volatile substances such as SO 2 and NH 3
- SO 2 and NH 3 behave completely differently from the abovementioned high-boiling substances. They are only incompletely removed by the conventional adsorption filters, and the equilibrium with the adsorption particles is such that the volatile substances are later released after initial binding. A permanent bond is therefore not guaranteed.
- One way to improve this insufficient adsorption is to impregnate the activated carbon with acidic or basic additives. For example, if you want to remove NH 3 from a gaseous mixture, such an impregnation with phosphoric acid can be carried out; on the other hand, if SO 2 is to be removed, prior impregnation with K 2 CO 3 is advisable.
- the undesirable substances enter into a chemical reaction with the impregnating agent and are permanently and irreversibly removed from the gas mixture in this way.
- the impregnation means that you are able to provide filters with an improved cleaning effect. However, the impregnating agent is consumed, with the result that after a certain time the cleaning capacity is exhausted.
- the impregnation of the adsorber particles affects the original adsorption capacity of these particles in terms of both the total capacity and the adsorption kinetics.
- the adsorber particles will remove undesirable substances from gas mixtures more slowly and in a smaller amount compared to their original performance.
- the adsorber particles establish a new balance between the originally existing adsorption performance and the chemical adsorption of the impregnating substance. With a large amount of impregnation substance, a considerable deterioration of the original adsorption performance is found, especially if there is an unfavorable distribution of the impregnation substance.
- DE-A-197 27 295 therefore proposes to provide a filter with high air permeability to which ion exchange beads are fixed.
- ion exchange beads can be strongly basic anion exchangers or strongly acidic cation exchangers. If strongly basic anion exchangers are used to load the filters, air streams in particular can be cleaned of gaseous acidic substances, especially sulfur dioxide. The use of strongly acidic cation exchangers enables the effective removal of gaseous basic substances, such as ammonia.
- the invention is therefore based on the object of providing a filter material which, with good adsorption kinetics and high capacity, can remove even the smallest traces of acidic and basic gases and other contaminants from the air stream.
- Another object of the invention is to adsorb the residual monomers remaining in the ion exchange materials and the reaction products of the ion exchange materials.
- the first adsorbent layer consists of impregnated activated carbon material and the second adsorbent layer consists of ion exchange materials.
- Another preferred embodiment of the invention contains ion exchange materials as the first adsorbing layer and impregnated activated carbon material as the second adsorbing layer.
- Another preferred embodiment of the invention contains three adsorbent layers.
- these three layers can optionally be configured from different materials, preferably ion exchange materials and impregnated as well as unimpregnated activated carbons, and sequences: Examples of these are:
- the filter material according to the invention consists of a carrier layer and a first adsorbing layer of impregnated activated carbon connected to this carrier layer. There is a second adsorbent layer on top, which consists of ion exchange materials.
- first adsorbing layer consist of ion exchange materials and the second adsorbing layer to consist of impregnated activated carbon material.
- the filter material according to the invention consists of a carrier layer and three adsorbent layers which, depending on the application, consist of two layers of ion exchange material and a layer of impregnated activated carbon or one layer of ion exchange material and two layers of impregnated activated carbon. These layers are applied in different orders, adapted to the requirements.
- the total adsorbent layer has a surface density of 200 to 1200 g / m 2 , preferably 300 to 1000 g / m 2 .
- the carrier layer and the total adsorbent pad are covered with a cover layer which is firmly connected thereto.
- All adsorbent layers can be applied either in layers or as a uniform layer of different adsorbents with suitable mixing ratios.
- suitable mixing ratios especially in the case of mixtures of ion exchange materials, are between 5: 1 and 1: 5, preferably between 3: 1 and 1: 3.
- cation exchangers Weakly or strongly acidic ion exchangers (cation exchangers) with e.g. Carboxyl groups or sulfonic acid groups and on the other hand weak or strongly basic ion exchanger (anion exchanger) with e.g. Amine function used. Mixtures of cation exchangers and anion exchangers can also be used advantageously for the purposes of the invention.
- alkali-impregnated activated carbon materials are used for ion exchangers containing sulfonic acid or carboxyl in order to collect the slightest release of acid-forming agents from the polymer structure.
- acid or metal salt impregnated e.g. Activated carbon materials impregnated with copper salt are used to collect the least amount of ammonia or amines released from the polymer structure.
- the polymeric adsorbents ie the ion exchange materials
- gases relevant to clean rooms such as ammonia, amines, nitrogen-containing heterocycles, silazanes, hydrogen chloride, hydrogen fluoride, sulfur dioxide, NO, and acetic acid.
- gases relevant to clean rooms such as ammonia, amines, nitrogen-containing heterocycles, silazanes, hydrogen chloride, hydrogen fluoride, sulfur dioxide, NO, and acetic acid.
- activated carbon materials suppresses the undesirable trace emission of agents and also absorbs the inevitable outgassing of residual monomers from the polymer structure.
