Scrubbers - Import export

In many incineration and industrial plants of various sectors as well as in the municipal sector, dust emissions are produced during production processes. These emissions must be purified before they are released into the atmosphere The resulting dusts can be sticky, wet, dry or combustible and have different particle sizes. Often industrial dusts are between 0.1 and 1000 μm in size and vary greatly in composition. They are also present in various concentrations and combinations with other pollutants. Compared to dry separators, wet scrubbers have the great advantage that fires or explosive mixtures cannot occur. Depending on the industry and area of application, such as in incineration plants, wet separators are indispensable.

The walkbehind scrubberdrier Scrubmaster B12 is ideal for use in small areas and has a particularly distinctive benefit it is very compact and therefore easy to transport. Thanks to its low weight and collapsible steering bar, this machine even fits into the boot of your car. This Scrubmaster provides a cleaning performance of up to 1,500 m²/h.

In environments with normal to high levels of coarse dirt, the Scrubmaster B400 RM plays its trump cards to the full. Coarse dirt is collected during dry sweeping to clear the path for the brushes and enable thorough wet cleaning. After the cleaning job is done, the dirt hopper can be quickly and easily emptied by hand.

The Scrubmaster B400 RH with high dump is the perfect choice for environments where plenty of coarse dirt regularly accumulates, e.g. in production or exhibition halls. Equipped with a 150litre dirt hopper, the vacuum sweeper and scrubberdrier combi machine can cope with large amounts of coarse dirt. Larger pieces of debris can be picked up by hand and thrown into the dirt hopper manually through the integrated coarse dirt flap.  

A bio scrubber combines physical scrubbers with a biological activation unit. In this process, air polluted with a wide variety of pollutants is cleaned with the aid of a washing liquid which is loaded with microorganisms and biocatalysts (various enzymes) taken from nature. The washing water absorbs the exhaust air and pollutants from the air. Subsequently, added microorganisms oxidise them. These microorganisms use the air pollutants as substrate and nutrient medium and convert them into naturally formed decomposition products such as CO2, water, and biomass. Here, the washing water is continuously regenerated and used in a closedcircuit water treatment system. TYPICAL APPLICATION AREAS These plants are primarily used for watersoluble ingredients of the exhaust air. The usual pollutants that are filtered from the exhaust air with the help of bio scrubbers include aldehydes such as formaldehyde, alcohols, ketones and other hydrocarbon compounds.

Operating principle With this type of scrubber, coarser solid particles and fibres are filtered out of the exhaust air. The DLP (Dust Low Pressure) scrubber from WesselUmwelttechnik has a number of advantages. In addition to a long operating period, this wet dust collector system scores with a constant separation performance. Wessel uses only highquality materials to manufacture scrubbers. This results in a high chemical resistance. Thanks to automatic monitoring of the process parameters during operation, the highest possible operational reliability is guaranteed. The system reacts automatically to changes in the inlet conditions. All in all, the DLP wet scrubber is easily operable due to the practiceoptimised control system. The power consumption is comparatively low due to low pressure losses. Typical areas of application The DLP scrubber is used, among other things, in connection with the Wessel BIOCAT scrubber, which is used for biological exhaust air cleaning.

Industrial air scrubbers are used to purify the exhaust air of pollutants, for example in the chemical or pharmaceutical industry. As soon as the exhaust air meets the legal requirements for clean gas values, it can be returned to the environment. Absorptive exhaust air purification by waste gas scrubbers is a frequently used technology. Gas scrubbers are suitable for removing pollutants, aerosols and dust from the exhaust air. Especially watersoluble exhaust air components are separated with high efficiency.

The BIOCATDUOscrubber from WesselUmwelttechnik consists of two units. One unit is the already mentioned BIOCATscrubber. A second unit, the DLP (Dust Low Pressure) scrubber stage, is a cleaning stage for separating dust and fine fibres from the exhaust air. With the BIOCATDUOscrubbers from Wessel, gaseous pollutants as well as dust can be removed from the exhaust air at the same time. The BIOCATDUOscrubbers have two separate washing water circuits for this purpose. It is characterised by a compact design, as both units are housed in one column. COMMON USE CASES The BIOCATDUOscrubbers are used in the woodbased panels industry, for example. More precisely where MDF boards (medium density fibre) and moulded fibre parts are produced. Here the exhaust air contains fine wood fibres which have to be filtered out of the exhaust air. Furthermore, pollutants and odours must also be reduced.

Operating principle The AGGLOControl scrubber does an excellent job separating the smallest particles and aerosols. This dust collector is suitable for removing fine particles down to grain sizes of less than 3 μm. This makes the AGGLO scrubber from WesselUmwelttechnik predestined for use in various industrial contexts. Exhaust gases and exhaust air of various types are filtered efficiently and, above all, costeffectively, and raw gas is freed from dust. Clean gas is released into the atmosphere that has been purified of over 95 % of particles from 1 μm in size. With the AGGLOControl scrubber, the higher the dust density, the more efficient the separation of the contaminants. The AGGLOControl scrubber from WesselUmwelttechnik scores with its compact and spacesaving design, which can be accommodated on any industrial site.

Multiventuri scrubbers are suitable for the separation of adhesive aerosols and for fine dust in humid waste air as these filtrating separations lead to adhesion, clogging and thus to irreversibel high filter resistance. In a wet separating process, the particles are washed out and thus cannot adhere.
