Oil-water separator for separating micro-seston of bilge

Abstract

The invention discloses an oil-water separation device for separating tiny floating substances in the bilge, which is composed of a primary processing device and a secondary processing device; Filtration removes tiny floating substances such as mud and sand; the secondary treatment device relies on gravity separation and a coalescer installed in its lower space to finally separate the residual oil in the emulsion after the previous stage removal treatment, so that the oil concentration reaches the discharge Treated water below the limit value is discharged from the discharge device to the outside of the ship.

Description

technical field [0001] The invention relates to an oil-water separation device, in particular to an oil-water separation device for separating tiny floating substances in the bilge. Background technique [0002] Traditional oil-water separation devices for ships mainly include gravity separation, coalescer and adsorption separation devices. In ships navigating in muddy waters, since the channel contains tiny mud and sand, of course, the bilge in the locomotive room also contains a large amount of solid substances such as such tiny sand and mud. When the bilge is treated with a traditional oil-water separation device, These tiny solid substances will cause poor gravity separation performance, clogging of coalescers or adsorption materials, etc., and the oil-water separation device cannot fully function, and the oil concentration of the treated water is difficult to reach below the discharge standard. Contents of the invention [0003] The object of the present invention is...
