WESSEL-UMWELTTECHNIK GMBH

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.

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.

Adsorption plants are an efficient way of filtering VOC (volatile organic compounds) or other pollutants from exhaust air, flue and exhaust gases in industrial and municipal applications. In comparison to absorption processes, in which harmful substances are bound by the use of liquids, an adsorption plant concentrates the pollutants These are physically attached to an adsorbent such as zeolite or activated carbon. The adsorption process is efficient and costeffective, especially for low to medium pollutant concentrations in large volume flows. If necessary, concentrated solvents, for example, can be recovered and reused with the help of other technologies. Especially for exhaust air streams with low or medium concentrations of VOC and other harmful exhaust gases, the use of socalled VOC concentrators is of great advantage.

With heat recovery systems in industrial environments, the heat contained in the exhaust air is efficiently used to heat air or water. A very efficient use of this energy is the preheating of dryer supply air. The heat can be used continuously here. This warm exhaust air is also suitable for heating buildings. Depending on the local conditions, both airtoair heat exchangers and airtowater heat exchangers can be used for this purpose. The heated air, in turn, is fed into production and factory halls or other areas of the building. This type of supply air heating is particularly costefficient. Such recovery systems also have a positive effect in terms of environmental compatibility. Waste heat from industry that is harmful to the climate is no longer released into the environment but remains in the cycle of the production process or building heating. The systems are also suitable for cooling rooms when outside temperatures are hot, for example.

Exhaust air purification and heat recovery systems are generally not standard applications, even if individual assemblies are now modular. We have made it our goal to offer our customers the best solution for their task. To do this, we take a step back with our customers in order to gain an overview of the whole. Together we look at how the exhaust air is generated and try to start our concepts right at the point of origin. Only then can we decide which exhaust air system is the most economical when considering the total cost of ownership and compliance with the limit values. Should an extended consideration be necessary, we can accompany you from basic to authority to detail engineering. In addition, it is not uncommon for pilot tests to be offered, which lead to the later real scale of the systems by means of scaleup. With these consulting and engineering services, we offer you a manufacturerindependent package with which you can make the right decision for your company.
