LOW ENERGY CONSUMING GARBAGE PATCH GATHERING AND CLASSIFYING EQUIPMENT AND METHOD USING CATAMARAN

摘要

PURPOSE: An energy-saving apparatus and method for collecting and sorting large marine waste using a catamaran are provided to efficiently collect and sort marine waste using a small amount of energy. CONSTITUTION: An energy-saving apparatus for collecting and sorting large marine waste using a catamaran (30) comprises a bow pulverizing part (40), a density-based sorting part (50), a collecting part, and a triboelectrostatic sorting part (70). The bow pulverizing part collects waste approaching to the bow of the catamaran and pulverizes the collected waste. The density-based sorting part is formed in a tunnel structure and sorts the pulverized waste pieces depending on the density of the waste pieces. The collecting part is installed in the density-based sorting part in a mesh structure and collects the sorted waste pieces. The collected waste pieces move on a vibrating belt (71) and are charged with different electrodes. The triboelectrostatic sorting part sorts the waste pieces moving on the belt depending on the charged electrode difference of the waste pieces.
