Title:
THREE-SECTION OIL-WATER SEPARATION TWO-DIMENSIONAL SINUSOIDAL WAVE COALESCING PLATE GROUP DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/008198
Kind Code:
A1
Abstract:
The present invention relates to the relevant technical field of oil-water separation, and in particular to a three-section oil-water separation two-dimensional sinusoidal wave coalescing plate group device, comprising several coalescing plates distributed at intervals. An upper contour line of a cross section and/or a longitudinal section of each coalescing plate is a first sinusoidal curve, and a lower contour line thereof is a second sinusoidal curve, the first sinusoidal curve having a wave height greater than that of the second sinusoidal curve. A flow passage extending from a reference plane to a wave crest comprises a floating section, a coalescing section and an escape section, which are sequentially connected. In the present invention, by using the coalescing plate having an upper and a lower surface with different wave heights and a consistent period, the probability of oil droplets colliding with a plate surface and thus coalescing is increased; in addition, an arc-shaped section is provided in the middle of the lower surface of the coalescing plate, so as to divide the flow passage formed by two adjacent coalescing plates into the floating section, the coalescing section and the escape section, such that the oil droplets accelerate to float at the floating section, the retention time of small oil droplets is increased by means of the coalescing section so as to facilitate the coalescence and enlargement of the small oil droplets, and then the oil droplets stably float at the escape section through an escape hole, thus achieving oil-water separation. The device occupies a small area and has a high separation efficiency.
