Mixer installation in air-supported roofs for flexible gas storage
Maximising biogas potential with efficient agitators from Peters Mixer
Eupen, October 2017. Whether you use a paddle-stirrer for demanding substrates or a rod agitator, which can be retroactively installed in the container – powerful mixing performance has a significant impact on efficiency. For over 20 years Peters Maschinenbau, Eupen, Belgium, has been building and developing agitator systems for the biogas industry. One of our most proven systems is the EXCENTRO V paddle stirrer, which was specially developed for difficult substrates.
Based on this sophisticated and highly reliable technology Peters have now developed the EXCENTRO S paddle stirrer. This an oblique version of the renowned EXCENTRO V (vertical) agitator system. Just like its partner system, its special advantage is that all of the maintenance and replacement work on the EXCENTRO S can be carried out without emptying the digester. Now this even applies to digesters with flexible gas storage instead of concrete covers. For operators this means the minimum amount of downtime for the plant.
Just like the EXCENTRO V, the EXCENTRO S also has a gear reducer motor with an output of between 7.5 and 15 kW. High quality and robust materials guarantee smooth low-maintenance operation. The EXCENTRO S paddle stirrer system is available in three versions with 4, 6, or 8 paddles. The full diameter of the system is 3 m and the length is between 5 and 10 m. The EXCENTRO S not only ensures optimum efficiency in new plants, it can also be installed to upgrade existing plants.
The newly developed "Methabox System", a built-in option for flexible gas storage, such as air-supported roofs, was developed especially for flexible gas membranes. Air-supported roofs or foil roofs are often used as flexible biogas storage tanks and gas-tight silo covers for biogas plants. The biogas that is produced is collected above the liquid level of the respective digester and safely stored temporarily in a so-called double-membrane or film storage.
These air-supported roofs mainly consist of a PE film and an outer weather protection film made of PVC. The dome shape provides maximum storage volume. However, for the installation of biogas agitators this construction poses a greater challenge than the installation in concrete or wooden covers. That is why Peters Mixer have developed the new "Methabox System", which is easy to install even in air-supported roofs.
