Pollutant/exhaust gas purification apparatus with water treatment cartridge for heating boilers

摘要

Air pollution by motor vehicles, aircraft and not least by oil, gas and coal heating systems has become unacceptably high. If countermeasures are not taken as soon as possible it can be predicted that difficult times lie ahead for humanity due to the pollution we have produced ourselves. In Patent Application P 3840437.0, a cavity catalyst is provided for purifying exhaust gases of heating boilers. This is currently under test so that measured values are still not available. The invention described here has a completely different exhaust gas purification method, that is to say the heating boiler exhaust gases, before entry into the stack, are purified of the toxic carbon monoxide and sulphur dioxide in a stainless steel cylinder by a steam jet, the conical wire filters which are integrated in great number in the manner of a column in the stainless steel cylinder perform the filtering out of the toxic gases and conduct these downwards dropwise at the outer rim of the filters. Only small amounts of waste water are formed by this method. A water treatment cartridge which is installed upstream of the electric steam generator prevents scale formation in the latter, an upstream fine water filter preventing blockage of the nozzle. Scale formation in the continuous flow heater built into the heating boiler is also avoided by this measure. The cleaning effect of the water freed from calcite is greatly enhanced by this apparatus.
