Scrubbers
Linear flow scrubber
Next generation scrubber for non-ferrous metallurgy. Compact, efficient and cost saving.
Linear Flow Scrubbers are adjustable and high-efficiency scrubbers that represent a substantial advancement on the already mature technology of the Radial Flow Scrubbers.
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.
Best applied in copper smelting furnaces or converters, zinc smelters and roasters, lead smelters, molybdenum roasters, nickel-copper / platinum smelters and other pyrometallurgical processes.
However, Linear Flow Scrubbers are not to be exclusively used for the non-ferrous metallurgical industry.
Particular features

- External drives for scrubber adjustment
- CFD optimized nozzle arrangement and flow conditions
- Automatic gas pressure drop control
- Steady scrubbing at fluctuating gas flow rates
- Energy saving
- Wide range of volume flow 1:100 at constant pressure drop
- Allows for the accommodation of several scrubbing stages in a single vessel
- Enlarged scrubbing section/reaction line lead to high efficiencies
- High removal efficiencies with low pressure drop
- Compact design, smaller footprint and reduced height
Working Principle
How do Linear Flow Scrubber work?
The raw gas enters from the top. The scrubbing liquid is injected though peripherally arranged nozzles upstream the scrubbing zone. The gas and the scrubbing liquid enter from above and pass through the scrubbing zone. The scrubbing zone is characterized by an extended reaction line or gap that is formed by a movable displacer, with tapers towards the top, and a diffuser attached to the casing.
The relative velocity between the gas and the scrubbing liquid, which is decisive for scrubbing efficiency, occurs along the reaction line. By lifting or lowering the displacer the cross-section of the scrubbing zone can be varied, which allows, even with changing gas volumes, to maintain the gas velocity constant in the reaction line and to keep a constant pressure drop across the scrubbing zone. In this way, defined collecting efficiency can be ensured. The differential pressure is the control parameter.
In cases where gases are hot and not saturated, linear flow scrubbers can be combined with an upstream quench stage for raw gas saturation and pre-dedusting.

GEA y Pulmuone honran a generaciones de artesanos de la pasta fría
Cuando el productor surcoreano de alimentos de origen vegetal Pulmuone planteó a GEA el reto de desarrollar un giro moderno del tradicional fideo frío masticable (naengmyeon), los expertos en I+D de GEA estuvieron a la altura. Ayudaron a crear lo que ahora es un éxito comercial producido con menos agua y electricidad que los métodos antes existentes. El resultado también es fiel a los orígenes tradicionales del plato, así como a las raíces de salud, bienestar y sostenibilidad de Pulmuone.
