Title: Dirk Hankel: Innovator in Environmental Technology
Introduction
Dirk Hankel is a notable inventor based in Mühlheim, Germany. He has made significant contributions to the field of environmental technology, particularly in the thermal separation of organic and inorganic substances. With a total of 4 patents to his name, Hankel's work focuses on innovative processes that address contamination issues in various materials.
Latest Patents
Hankel's latest patents include a process for thermally separating organic and/or inorganic substances. This process involves the thermal separation of these substances from contaminated materials and solid aggregates. The contaminated material is pretreated and heated in a furnace, which may include a rotary kiln or a fluidized bed furnace. During the heating process, the material is treated with recycled hot gases or steam, and oxidizing agents are used to enhance the separation. The processing gases, which contain water vapor, are dedusted, and a significant portion of these gases is recycled back to the furnace. The remaining gases are condensed, allowing for the removal of pollutants through wet chemical or physical processing.
Another significant patent by Hankel is the process of dressing contaminated soils. This method involves grinding contaminated soils in a drum with added loose pieces acting as grinding elements. The process is energy-efficient, requiring between 4 to 16 kWh per 1000 kg of throughput. The ground material is then separated into a purified fraction and a pollutant concentrate through sieving. The resulting sludge is dewatered, and the purified soil is delivered as a final product.
