Suction pipes draw waste oil droplets and chemicals from collection zones

摘要

An assembly collects waste liquids such as oil droplets and chemicals in one or more vessels (2) with perforated covers (3) over a protected area (1) with collection zones for the different wastes. The waste collection zones are linked to a collection vessel (16) by pipes. The novelty is that the pipes (12) are suction pipes, and that each collection zone surrenders waste to an active suction unit (10), its respective branch (12) and main collector pipe (13). Gaps (5, 6, 7) are allowed between the covers (3) to accommodate the pipes (11, 12, 13). The wastes are transferred from the main pipe (13) to the main collection tank (16) by a pump (17) for separation.
