Bulk materials heat exchanger integrated with pneumatic conveying

摘要

The BULK-X-CHANGE~R bulk materials heat exchanger from Coperion Waeschle GmbH & Co. KG, Weingarten, Germany, can now be integrated into pneumatic conveying systems. The company says that the direct installation now considerably improves heat transfer, permitting the combination of the two processes - conveying and temperature control - within one single system. This makes the handling of bulk materials even easier than before. Through changes in design, Coperion Waeschle has now extended the scope of application of the previously gravimetrically fed BULK-X-CHANGE far beyond the handling of free-flowing powders and granules. This new integrated version is also suitable, for example, for fine particle powders that have a fluidizing or cohering tendency during discharge from the silo. Pneumatic conveying systems are frequendy used for the handling of such powders. The basic principle of the new process (patents pending) is the direct installation of the BULK-X-CHANGE bulk materials heat exchanger into a pneumatic conveying line. The pneumatically conveyed powder, together with the conveying gas, enters the vertically arranged heat exchanger from below.
