Title: Walter Spahn: Innovator in Exhaust Gas Purification and Bulk Material Cooling
Introduction
Walter Spahn is a notable inventor based in Frankfurt-am-Main, Germany. He has made significant contributions to the fields of exhaust gas purification and bulk material cooling. With a total of 3 patents to his name, Spahn's work reflects a commitment to innovation and environmental sustainability.
Latest Patents
One of Spahn's latest patents is a process for the removal of impurities from exhaust gases. This innovative method involves cooling the exhaust gas using a circulation gas and condensing impurities through two groups of reversible heat exchangers. Each group consists of two precoolers and one low-temperature cooler. While impurities condense in one group, they are thawed in the other, simplifying the control process with only one precooler used in each group. This design requires just two simple control systems, which can be easily programmed for the purification process. Additionally, the temperature increase of the circulation gas can be utilized for heating purposes in the thawing group.
Another significant patent by Spahn is a device for cooling bulk material using low-boiling liquefied gas. This device features a precooling zone and a spraying zone, with the precooling zone inclined downward toward its discharge end. Attached to this end is a rotatable drum-shaped chamber, designed as a worm conveyor for spraying and draining. When used for scrap tires, a spray pipe is included at the discharge end, featuring a ring mounted on the internal wall that corresponds to the average tire thickness.
