- the invention relates to a filter system for the elimination of particles, gases and biological loads, in particular air-polluting particles, gases, toxins, viruses and bacteria.
- Such a broadband filter system is known from DE 10 2004 027 354 Al.
- This modular and multivalent broadband filtration system has both a purely mechanical separation effect and physical, chemical and antimicrobial effects against air pollutants, while at the same time registering and regulating the monitoring of the load level of the system.
- superoxidation plants, fine filters, adsorption filters with heating, ionization grid, catalysts, nonwoven webs of stabilizer fiber and carbon fiber and sensors for control are used.
- DE 103 30 368 A1 describes a method for identifying and / or differentiating substances displayed by sensors in gas mixtures a sensor, at least part of the substances detected in gas mixtures and / or at least part of the data generated by this sensor are automatically evaluated by a computer program and the identification and / or differentiation of substances on the basis of specifiable criteria and / or patterns performs.
- a computer program In the evaluation by the computer program methods of artificial intelligence are used.
- the result thus obtained is displayed, directly or after being transmitted by a communication system.
- the filter elements are arranged at least in pairs, so that when detecting a filter breakthrough can be switched to a corresponding other filter element that takes over the adsorption, while the "spent filter element" is regenerated in the system by desorption and / or taking out and neutralization of the harmful gas components
- the filter stage thus remains in the overall system and is available to the system again after the desorption phase.
- a filter precursor a primarily mechanical filter stage for retaining particles below 1 ⁇ m.
- the particles add the individual filters to this filter precursor and reduce the flow rate of the gases and gas mixtures. Therefore, this stage has in known manner sensors for detecting the pressure difference. Above a certain value, the filters must be replaced
- a filter main stage with a plurality of filter units arranged in parallel in the optionally the gas flow of the filter Pre-stage is initiated by means of switching elements, wherein at least two filter units forming a pair are equipped with the same gas filters for adsorbing Gasverunreini ⁇ tions (x, y, z) from the gas stream and are controlled alternately and
- a subsequent filter stage for the gas stream which is equipped with at least one multi-function sensor which analyzes the gas flow from the main filter stage with respect to the presence of at least gas contaminants (x, y, z),
- the overall system is thus a 3-dimensional filter with parallel, similar regenerable filter stages.

- a main filter stage with a plurality of parallel filter units, in which optionally the gas flow of the filter precursor is introduced by means of switching elements, wherein at least two pairs of filter units are equipped with the same gas filters for adsorption of gas impurities (x, y, z) from the gas stream and are mutually driven and
- a subsequent filter stage for the gas stream which is equipped with at least one multifunction sensor which analyzes the gas flow from the main filter stage at least with respect to the presence of gas contaminants (x, y, z),
- gas contaminants (x, y) detected by the multifunction sensor of the filter precursor are used as a signal for sensitizing the multifunction sensor of the filter output stage to check the presence of the gas impurities x, y and wherein, depending on the size of the measured values of the multifunction sensor of the filter end stage relating to the gas contamination (x, y) switching over to a second filter unit of the filter pair of the main filter stage takes place, so that it takes over the filtering of the gas stream coming from the filter precursor and the first filter unit of the filter pair is available for desorption.
- a further gas contamination (u) is detected by a multi-function sensor, which is not filterable by the gas filter for the impurities (x, y, z)
- a further gas contamination (u) is detected by a multi-function sensor, which is not filterable by the gas filter for the impurities (x, y, z)
- gas filters are controlled, including a filter of a pair for the impurity (u).
- the contamination of the gas or gas mixture is adsorbable through the filter elements of the main filter stage.
- the filter precursor and / or the filter end is equipped with at least one multi-functional sensor, the gas flow over the entire surface analyzed with respect to the presence of gas contaminants (v, x, y, z), wherein when measuring a gas contamination (v) by a multi-functional sensor which is not adsorbable by the gas filters of the main filter stage, a switching of the gas flow takes place in the exhaust duct.
- a gas contamination v
