Scrubbers
Since 1950 ranking among the most outstanding high-efficiency scrubbers. Flexible and capable of mastering manifold industrial off-gas problems.
In the iron & steel industry the Annular Gap Scrubber - invented by Bischoff - is used as gas cleaning equipment and simultaneously as flow or pressure control unit for complete processes.
Typical applications are blast furnaces and steelmaking plants.
In general the annular gap scrubber consists of two stages. First the gases enter into the pre-scrubber stage which is passed with low velocity for efficient cooling and separation of coarse dust.
Several spray nozzles are installed inside the pre-scrubber and continuously spray water into the gas. The temperature of the gas decreases rapidly down to the saturation temperature.
The dirty waste water which is flowing down the scrubber shell is discharged ahead of the second scrub¬bing stage. The connection pipe to the RS-element is located in the lower part of the pre-scrubber.
In the second stage, the fine de-dusting takes places via the GEA BISCHOFF RS-elements with variable annular gap. The most important part of the RS-scrubber is a conical element, which is axially adjustable – driven by a hydraulic cylinder - and forms an annular gap together with the conical shell. One GEA BISCHOFF spray nozzle, arranged centrally and spraying unilaterally, is installed upstream of the RS-element.
This arrangement of the spray nozzle guarantees a regular water distribution over the annular gap cross section which is an important precondition for efficient gas cleaning.
Gas and water are forced through a zone of high turbulence having a corresponding intensive interaction leading to excellent dedusting efficiencies. Dirty waste water is discharged in the bottom section and the gas flows to the downstream demister where most of the remaining droplets are separated.
High performance separators for fine dusts and aerosols, available in different scales. Also with with customized solutions.
Versatile as fast absorber, de-duster or gas cooler. Operate according to injection principle: no pressure loss, but a pressure increase in the gas flow.
Next generation scrubber for more than the non-ferrous metallurgical industry. Used for dust and particulate removal in saturated waste gases, Linear Flow Scrubbers offer increased energy savings and efficiency thanks to their high adaptability, adjustability capacity to steadily scrub at fluctuating gas flow rates.
Adjustable flow scrubbers with high collecting efficiencies achievement even when working with critical substances. Mainly used for either gas cooling (to reduce the temperature by water evaporation) or gas cleaning (to condense aerosols and remove solid impurities).

Das Leben von Michele Schneider nahm eine unerwartete Wendung, als sie ihren Ehemann Virlei heiratete, einen jungen, ambitionierten Milchviehhalter, und gemeinsam mit ihm den Milchviehbetrieb „Fazenda Inovação Schneider Milk“ in Brasilien gründete. Als Quereinsteigerin in der Milchviehhaltung entdeckte Michele rasch ihre Leidenschaft für die Tiere und die tägliche Arbeit auf dem Hof. Mit dieser Begeisterung wuchs jedoch auch ihr Arbeitspensum.
