Apparatus and method for the disposal of health-endangering gases, vapours, dusts and fumes by adsorption to surfactant substances

摘要

Said gases etcetera occur in earthworks in contaminated soils and when transporting removed soil, also in the case of tips which are created during earthworks and in the case of welding work on rails. A building site can be covered by means of a hall (3) or by a roof (11). A pipe (17) leads from the covered space to an extraction unit (19) which conveys the air into the open air through an exhaust air purifier (21) in order to adsorb the noxious substances on surface-active substances. A two-part mat with an upper mat (42) which is impermeable to gas is used to cover mines, tips and/or vehicle loads. The upper mat has in its central area a connecting element for a hose which leads to the extraction unit (19). Processing tools of earth moving units such as excavator shovels (68) and boring machines (74) can be covered by a transparent bell (60) out of which the air is also sucked, etcetera. In order to remove noxious fumes during welding operations on rails, the workplace can also be covered and the air sucked out and purified. IMAGE
