Scrubber for an oil-only recovery apparatus

摘要

An improved scrubber that uses a stream of air to blast the oil off the oil-laden conveyer chains of oil-only recovery apparatus is disclosed. The improved scrubber eliminates the need for conventional scouring components that physically contact the conveyer chain. The scrubber includes a blower, a series of air ducts, and an elongated nozzle. The air flow generated by the blower is communicated through the air ducts and directed onto a length of the oil-laden conveyer chain within the reservoir chamber of the recovery apparatus by the nozzle to blast the crude oil off the conveyer chain. The scrubber also includes a collection baffle positioned directly behind the length of the conveyer chain, which provides a surface area upon which the liquid oil collects and upon which the gaseous oil particulate may agglomerate and condense, before collecting at the bottom of the reservoir chamber. The scrubber of this invention can be used as part of an open or closed air circulation system on an oil-only recovery apparatus.
