Problems solved by technology

These devices have their own advantages and disadvantages. Generally speaking, the oil removal effect is not ideal. The residence time is too long, small-sized oil droplets (such as emulsified oil, dissolved oil) cannot be removed deeply, the filler is easy to block, and sludge is generated to cause secondary pollution. And other issues

Embodiment Construction

[0020] The present invention will be described in further detail below according to accompanying drawing:

[0021] The oil-water separation device includes a cyclone 1 with a U-shaped underflow pipe and a horizontal coalescing oil-water separator 2 with the function of uniform liquid distribution, see attached figure 1 . Among them, the cyclone 1 is used as the pre-separation zone, the horizontal coalescing oil-water separator 2 is used as the main separation zone, and the liquid outlet of the U-shaped bottom flow pipe of the cyclone is connected with the inlet of the horizontal coalescing oil-water separator. The horizontal coalescing oil-water separator is provided with an inlet liquid distributor 8, a rectifying sieve plate 9, a stainless steel plate corrugated packing coalescing area 10, a polypropylene wire mesh corrugated packing coalescing area 16, and an outlet liquid collector 20 in sequence. The stainless steel plate corrugated packing coalescing area 10 and the pol...

Abstract

The invention discloses oil-water separating device and method. The oil-water separating device comprises a swirler and a horizontal type agglutinating oil-water separator, wherein a bottom flow pipe of the swirler is in a U shape; the horizontal type agglutinating oil-water separator has the liquid uniform distributing function; an inlet liquid distributor, a rectifying sieve plate, a stainless steel plate ripple filler, a polypropylene gauze ripple filler, an outlet liquid collector, and the like are sequentially arranged in the horizontal type agglutinating oil-water separator, and the stainless steel plate ripple filler and the polypropylene gauze ripple filler are fixed by a limit grid plate; the U-shaped bottom flow pipe of the swirler and a filter screen arranged in the swirler can filter a small number of solid impurities contained in liquid so as to prevent the blockage of agglutinated fillers; the inlet liquid distributor and the outlet liquid collector ensure that the liquid is uniformly distributed; the rectifying sieve plate reduces the flow rate of the liquid to form lamellar flow; the stainless steel plate ripple filler provides a place for agglutinating and separating oil drops; and the polypropylene gauze ripple filler with an air floating device can further agglutinate and separate residual fine oil drops. The combination simultaneously has the effects of whirl, agglutination and air floatation and can realize the deep separation of oil and water.

Description

technical field [0001] The invention relates to the technical field of liquid separation, and provides an oil-water separation device and an oil-water separation method, in particular to an oil-water separator for processing oilfield production fluid. Background technique [0002] The existing oil-water separation technologies mainly include sedimentation method, centrifugal separation method, coalescence method, air flotation method, flocculation method, etc. The oil-water separation equipment commonly used in industry designed under the guidance of this method includes inclined plate degreaser, cyclone degreaser, etc. Oiler, coarse-grained degreaser, air flotation degreaser, etc. These devices have their own advantages and disadvantages. Generally speaking, the oil removal effect is not ideal. The residence time is too long, small-sized oil droplets (such as emulsified oil, dissolved oil) cannot be removed deeply, the filler is easy to block, and sludge is generated to cau...
