De-dusting of slight radioactive residues

Special preventive measures are necessary to prevent contamination spread of radioactive materials. This includes also firm housings to protect employees in their job against external and internal radiation exposition. The term „caisson“ is also used for such a housing. The exhaust of the housings is sucked through filter units, which prevent employees and evnironment from radiation exposition by particles in the exhaust air.
At „Nuclear Engineering Seibersdorf“ (NES) in Austria two identical cassette filters of type INFA-MICRON MKR were installed by a German plant contractor for nuclear technology. The filters made of stainless steel are used for the de-dusting of two stainless stell caissons in which radioactive waste is disaggregated, sorted and reconditioned. The dust particles which mainly originate from medical area, e.g. from radiation therapy and nuclear medicine, are led through the pre-filter into a central filter unit.
The cassette filters were plannedwith two filter stages in order to achieve a higher cleaning efficiency of the slightly nuclear dust. The dust-laden air enters the raw gas chamber of the filter housing via the raw gas channel. Afterwards the raw gas flows upwards through the 1st filter stage, separating the fine dust in the foldings of the filter cassette.The air of the 1st filter stage passes the 2nd filter stage (optional), which is used as safety filter, in the same direction.
Another preventive measure against the radioactive dust is the SAFE CHANGE system for a change of the filter cassettes free of contamination. A plastic bag is fixed at the access opening to the filter cassette. This plastic bag is fixed firmly on the so-called change collar with an elastic rubber ring. The filter element is pulled into the plastic bag when changing it. The plastic bag is securely closed and cut off from the change collar. A new filter cassette is connected via a new plastic bag to the change collar and is pushed into the filter housing. Therefore no dust can escape from the open filter during the entire process. The gas tight design of the filter units additionally prevents from possible dust contamination.

Trade Fair Schüttgut 2014
We hereby warmly invite you to participate in the 6th edition of Solids Dortmund (Schüttgut) and the 2nd edition of Recycling-Technik, both taking place on 21 & 22 May 2014 in the Westfalenhallen in Dortmund, Germany. Dortmund and the Ruhr region provide the ideal backdrop for these two shows: Handling bulk solids has long been an important commercial factor for the area, which is not only Germany’s industrial powerhouse but also one of the biggest and most economically dynamic conurbations in Europe. It is at this crossroads of supply and demand that Solids Dortmund (Schüttgut) and Recycling-Technik offer you a platform for making new business contacts and generating sales leads. The Ruhr’s exceptional urban infrastructure makes it easy to get around and, as a show venue, underscores easyFairs’ basic concept: doing business cost- and time-effectively. In just two exhibition days, suppliers, manufacturers and dealers can meet qualified trade visitors, engage with them in dialogue about specific projects and present solutions from a comprehensive spectrum of solids technologies: bulk goods services, material processing and/or handling, storage and warehousing, and (new in 2014) solids transport. By including multimodal transport systems and solids logistics in its exhibitor scope, Solids Dortmund 2014 (Schüttgut) now covers the entire solids handling process from start to finish. But these are not the show’s only new features! In 2014 the emphasis will be on providing more time and space for exchanges with peers and experts, doing business, and knowledge transfer: A comfortable ambience for business transactions: - Attractive new stand concepts, offered in tried-and-tested ‘all-in’ packages New networking areas: - Business-Bar and VIP & Speakers’ Lounge - Country pavilions – exhibitors from neighbouring EU countries present themselves Focus on content: - Expert lectures and discussions on four stages – and free attendance for all visitors - Integrated trade convention – dialogue and exchange of know-how between science, economy and politics In addition to the national reach it provides via its strategic location in the heart of German industry, Solids Dortmund 2014 (Schüttgut) also serves as an ideal springboard for international networking. Solids Dortmund 2014 (Schüttgut) is one of the Solids European Series shows, Europe’s largest series of trade shows for solids technologies. Together, the show’s five stops – Dortmund, Rotterdam, Basel, Antwerp und Krakow – gather over 900 exhibitors and more than 10,000 visitors in highly industrialised metropolitan areas. For further details, please visit www.easyfairs.com/solids. Extensive and up-to-the-minute information about Solids Dortmund 2014 (Schüttgut) and Recycling-Technik 2014 can be found on our website.
