DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

FIG. 3 is a view showing a sand-pan integrated slush reducing plate according to an embodiment of the present invention, FIG. 4 is a view for explaining an oil-water separating function of the sand-pan integrated slush reducing plate shown in FIG. And FIG. 5 is a view for explaining the floating prevention function of the sand / silt of the sand-pan integrated slush reducing plate shown in FIG.

Referring to FIG. 3, the sand-pan integrated slushing reduction plate includes a slush reduction reducing plate 310 installed in the longitudinal direction of the separator 100, two sandwich slashing plates 310 sloping on both sides of the lower portion of the slush reduction reducing plate 310, The fan 210 and the two flow restraining plates 320 slantingly coupled to both sides of the slush reduction reducing plate 310 at the spaced-apart upper positions of the respective sand pumps 210.

The slush reducing plate 310 may be a plate-like member vertically disposed in the longitudinal direction of the separator 100 so that one end thereof contacts the weir panel 110 (see FIG. 1). When a plurality of holes are formed in the body of the slush reducing plate 310 so that a roll or the like is generated in the separator 100, (E.g., oil, water, etc.) may be moved to another region through the holes.

In other words, as shown in FIG. 4, when a rolling motion is generated in the fluid, the fluid stored in the separator 100 is slung in a corresponding direction.

At this time, the fluid is prevented from moving by the slush reducing plate 310 and the slushing phenomenon can be reduced, and only a part of the fluid moves to another region partitioned through the holes formed in the slush reducing reducing plate 310 (See Fig. 4 (a)).

At this time, a collision occurs in the process of passing the fluid through the holes, so that the small water component existing in the oil accumulation layer and the small oil component existing in the water accumulation layer are bundled together to form water droplets and oil droplets. When the water droplets and the oil droplets are formed as described above, the water droplets descend to the water accumulation layer by the difference in specific gravity, and the oil droplets rise to the oil accumulation layer (see FIG.

In other words, the slush reduction reducing plate 310 according to the present embodiment not only reduces the slushing phenomenon caused by the rolling motion, but also effectively separates water and oil by allowing water and oil, which are moved by rolling motion, It is advantageous in that it can accelerate.

Referring again to FIG. 3, two sand fans 210 are slantingly coupled to both sides of the lower portion of the slush reduction reducing plate 310 to form a 'g' 'shape as a whole, The two flow restraining plates 320 may be slantingly coupled to both sides of the slush reduction reducing plate 310 so as to form a curved shape at the upper position.

The sand fan 210 induces the accumulation of heavy components such as sand and silt on the upper part of the sand fan 210. A hole is formed in the body of the sand fan 210 to pressurize the water jet nozzle 220 by the pressure of the water jetted by the water jet nozzle 220 After the sand and silt pass through the holes, they are discharged through the drain pipe 115 formed at the lower portion of the separator 100.

3 shows a case where the sand fan 210 is a plate member that is slantingly connected to the lower portion of the slush reducing plate 310. Each sand pump 210 has one end at a lower portion of the slush reducing plate 310 But may be formed in a U shape along the inner surface of the separator 100.

 Hereinafter, functions of the sand pump 210 and the flow control plate 320 will be described with reference to FIG.

5 (a), when crude oil flows into the separator 100, sand and silt are precipitated in the lower part of the separator 100 in the process of separating into oil, water, and other components, and the precipitated sand And the silt must be discharged to the outside through the drain pipe 115 in order to maintain the separation efficiency of the separator 100.

To this end, the water jet nozzle 220 installed at the bottom of the separator 100 injects water downward at a predetermined pressure.

Some of the sand and silt accumulated on the upper part of the sand fan 210 due to the pressure applied by the water jet nozzle 220 passes through the hole formed in the sand fan 210 and is discharged through the drain pipe 115. At this time, it is natural that the water accumulated in the separator 100 and / or a part of the water injected by the water jet nozzle 220 may be discharged together with the sand and silt.

However, some of the sand and silt accumulated on the upper part of the sand pan 210 move along the path formed by the sand fan 210 by the pressure applied by the water jet nozzle 220, and when the applied water pressure is strong, So that it rises along the vertical path formed by the signal reducing plate 310.

The raised sand and silt are accumulated on the upper side of the sand pan 210 by moving along the lower surface of the flow control plate 320 obliquely attached to the side wall of the slush reduction reducing plate 310 b)).

At this time, the flow control plate 320 may be attached to a height corresponding to the water accumulation layer, for example, to minimize the flow generated in the separator by reducing the moving path of the rising sand and silt. Of course, it is needless to say that the attachment position of the flow control plate 320 is not limited thereto.

As described above, by the pressure applied by the water jet nozzle 220, the sand and silt floating upward can be returned to a position where the sand and silt can be discharged to the outside through the holes formed in the sand pump 210, ) Can maximize the efficiency of sand and silt discharge.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the following claims And changes may be made without departing from the spirit and scope of the invention.
