The guide plate may be slanted so as to correspond to the oil transfer hole.

The water transfer holes may be alternately arranged at a height corresponding to the water accumulation layer and at a relatively upper position and a relatively lower position relative to the sequentially arranged droplet separation plate so that water is repeatedly moved up and down . Here, the water transfer hole may be provided with a grid plate having a gap.

The separator may further include a plurality of grid plates having different gaps formed in the water transfer holes. In order to induce water to be repeatedly moved upward and downward, the water transfer holes are formed in a grid having a relatively large total area of voids per unit area at a height corresponding to the water accumulation layer, The plates may be arranged alternately so as to be located at a relatively lower position or at a relatively upper position.

Other aspects, features, and advantages will become apparent from the following drawings, claims, and detailed description of the invention.

According to the embodiment of the present invention, since the flow direction of the fluid in each of the water accumulation layer and the oil accumulation layer is distorted, water droplets and oil droplets of small droplet sizes existing in each of the water accumulation layer and the oil accumulation layer are aggregated, So that they can be moved to the accumulation layer.

FIG. 2 is a view showing the structure of a separator provided with a plate for separating droplets according to an embodiment of the present invention, FIG. 3 is a view showing a shape of a plate for separating a droplet according to an embodiment of the present invention, FIG. 5 is a view showing a shape of a plate for separating droplets according to another embodiment of the present invention. FIG.

2 and 3, the separator 100 includes a crude oil inflow pipe 105, a weir panel 110, a drain pipe 115, a deformer pack 120, an oil discharge pipe 125, An extractor 130, a gas discharge pipe 135, and a plate for separating droplets.

The crude oil introduced through the crude oil inlet pipe 105 is stored in the separator 100 and the water, oil, and the like contained in the crude oil are separated into respective components by the specific gravity difference over time, And accumulates in the inner space.

In the separator 100, a defoamer pack 120 is installed to prevent bubbles on the surface of the crude oil, and oil separated and accumulated on the upper portion of the water accumulation layer overflows the weir panel 110, And is discharged to the outside through the rear oil drain pipe 125.

The gas components having a low volatile point pass through the mist extractor 130 and are discharged through the gas discharge pipe 135 after the water component is removed.

In the separator 100, a plurality of the droplet separation plates are spaced apart in the vertical direction so as to intersect the moving direction of the crude oil introduced through the crude oil inflow pipe 105 (that is, the direction approaching the weir panel 110) .

The plate for separating droplets has a plurality of plates 210 vertically spaced apart from each other so as to intersect with the moving direction of the introduced oil, an oil transfer guide 220 formed on the plate 210 at a position corresponding to the oil accumulation layer, And a water transfer hole 230 formed in the plate 210 at a position corresponding to the height of the water accumulation layer.

The oil transfer guide 220 may include an oil transfer hole 310 formed in the plate 210 and a guide plate 320 slantingly attached to the oil transfer hole 310.

The oil transfer hole 310 may be a long hole formed in the body of the plate 210 in the longitudinal direction or a plurality of holes spaced apart therefrom.

2 to 4 illustrate the case where the guide plate 320 is attached in a diagonal direction. However, the guide plate 320 may have various shapes, for example, in a shape of a rectangle, a letter V, a letter W, or an letter M It is natural that it can be combined.

The water transfer hole 230 is formed in each of the sequentially arranged plates 210 so as to allow the water to move downward and upward and move to the side of the weir panel 110 at a position corresponding to the height of the water accumulation layer Are arranged alternately on the lower or upper side.

The water transfer hole 230 may not be maintained in the through hole state, but a grid plate 330 may be disposed in which one or more voids are formed as illustrated in FIG.

The crude oil introduced through the crude oil inflow pipe 105 is separated into the oil accumulation layer and the water accumulation layer by the density difference in the process of moving toward the weir panel 110. The oil present in the oil accumulation layer is separated from the oil transfer guide 220 As shown in FIG.

At this time, the oil collides with each other due to the oil conveyance path being distorted in the course of passing through the oil transfer hole 310, collided with the guide plate 320, and the like, Water droplets of small droplet size become coalescing. The water droplets larger than the predetermined size will move (descend) to the water accumulation layer due to the specific gravity difference.

The water present in the water accumulation layer rises or falls through the water transfer holes 230 arranged alternately above or below the sequentially arranged plates 210 and moves toward the weir panel 110. In this process, Oil droplets of a small droplet size existing in the layer collide with each other while passing through the grip plate 330 to form oil droplets of a large droplet size and oil droplets of a large droplet size are caused to rise to the oil accumulation layer .

As described above, in the process that water and oil respectively present in the water accumulation layer and the oil accumulation layer are moved along the path formed by the water transfer hole 230 and the oil transfer guide 220, Causing a collision to form a large droplet sized water or oil droplet, and the formed water or oil droplet is moved to the corresponding accumulation layer by a specific gravity difference.

FIG. 4 shows a plate for separating droplets, in which the total area of the voids per unit area formed in the grid plate 330 provided in the water transfer hole 230 is different for each position.

For example, as a method of constructing the total area of the pores differently according to the position, there may be employed a method of making the sizes of the pores formed by the same number for each unit area to be different or a method of changing the quantity of the pores of the same size formed for each unit area There will be.

3 shows the structure of the plate 210 in which the positions of the water transfer holes 230 are alternately arranged on the upper side or the lower side. In FIG. 4, the water transfer holes 230 are different in size and position, A relatively large amount of water will be transported through a region having a large total area of pores.

Therefore, in order to allow the water to be transported while repeatedly raising and lowering, the first droplet-separating plate for each of the droplet-separating plates that are sequentially spaced apart has a lower area And the second droplet separating plate is disposed so that the total area of the pores is located at a higher position as the unit area is relatively large.

At this time, even if the porosity is different, oil droplets of a small droplet size included in the water accumulation layer can be grown into large oil droplets by the grid plate 330 installed in the water transfer hole 230, will be.

The separator 100 is provided with a plurality of spaced apart partition walls for crossing the direction of transfer of the fluid in the separator 100, thereby functioning as a kind of partition wall. As a result, It is natural that slushing in the substrate 100 may be suppressed.

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.
