Abstract: The adsorption device (1) for warfare agents from the exhaust air of ammunition disposal plants, comprises a housing (2) having an inlet for the exhaust air, an outlet for cleaned air, a supply chamber in which a supply line flows for fresh adsorbent material, an upper- (6) and a lower filter system (7), in which a first and a second filter bed from the adsorbent material are arranged and an outlet chamber (8) that has an opening for the used adsorbent material, and a control device, with which the concentration of the toxic substances in the exhaust gas is determined. The adsorption device (1) for warfare agents from the exhaust air of ammunition disposal plants, comprises a housing (2) having an inlet for the exhaust air, an outlet for cleaned air, a supply chamber in which a supply line flows for fresh adsorbent material, an upper- (6) and a lower filter system (7), in which a first and a second filter bed from the adsorbent material are arranged and an outlet chamber (8) that has an opening for the used adsorbent material, and a control device, with which the concentration of the toxic substances in the exhaust gas is determined during the transition of the lower filter system to the upper filter system. The adsorbent material is present in free-flowing form and is flow-throughable from the exhaust gas between the inlet and the outlet of the housing. The exhaust gas flows to the lower filter system and then to the upper filters system. The supply chamber from the filter bed of the upper filter system, the filter bed of the upper filter system from the filter bed of the lower filter system and the filter bed of the lower filter system from the outlet chamber are separated by a slide system (12), which is brought in a closed position in which the passage of adsorbent material is not possible, and in a open position in which the passage of adsorbent material is possible. The control device is an ion mobility spectrometer. Each filter system has a middle lower chamber, over which the gas is supplied or exhausted, an outer lower chamber, over which the gas is supplied or exhausted, and a lower chamber forming a filter bed filled with the adsorbent material lying between the middle lower chamber and the outer lower chamber. The outer lower chamber and the lower chamber filled with the adsorbent material circularly surround the middle lower chamber. All lower chambers have rectangular cross section. The side walls of the lower chamber filled with the adsorbent material are partially formed by a sieve-like or lattice-like structure. The volume of the supply chamber is equally larger than the total volume of all the filter beds. The supply line horizontally runs in the supply chamber and has several openings present in distance from each other. The slide system has a stationary sub-plate with several openings present in distance from each other and an adjustable slide opposite to the sub-plate. The slide system is V-shapedly or U-shapedly curved in the cross-section. The outlet chamber downwardly tapers itself to the opening in the funnel-shaped manner. An independent claim is included for a plant for highly toxic substances of warfare agents from exhaust air of ammunition disposal plants.
