Method and Apparatus for Evaporating Waste Fluids

摘要

A self-contained, portable, waste water evaporating apparatus is shown. A solar-operated submersible pump pumps waste water from just under the surface of a waste water pit, through a pair of automatic backflushing filters and out misters located around the bank of the waste water pit. At a predetermined pressure across the automatic backflushing filters, the automatic backflushing filters are reverse cycled, one at a time, to backflushing particles back into the waste water pit. Periodically, the misters are purged and/or cleaned to remove particles therefrom. In response to sunlight, solar panels provide DC voltage directly to the submersible pump. If pressure from the submersible pump gets excessive, a pressure relief valve removes the excess pressure.

主权项

1. A self-contained, portable, waste water evaporating apparatus for evaporating waste water from a remote waste water pit having banks there around, said apparatus comprising:
a floatation device in said waste water pit; a submersible pump suspended below said floatation device near a surface of said waste water pit; a pair of automatic backflushing filters on a cart on said bank; pump line connecting said submersible pump to said pair of said automatic backflushing filters; a plurality of misters located on said bank of said waste water pit; evaporation line connecting filter outlets of said pair of said automatic backflushing filters to said plurality of said misters; solar panels on said cart for providing electrical power directly to said submersible pump so that during sunlight said submersible pump pumps said waste water from said waste water pit through said pair of said automatic backflushing filters and out said evaporation line to said plurality of misters; pressure gauge across said pair of said automatic backflushing filters; filter controller connected to said pressure gauge so that if pressure of said pressure gauge exceeds a predetermined amount said filter controller operates backflushing valves on an inlet side of said pair of said automatic backflushing filters while maintaining flow of said waste water from said submersible pump so that each filter of said pair of said automatic backflushing filters is separately backflushed.
