Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a plate pack type separator for separating multi-

The present invention relates to a separator of a plate pack type, in which a baffle is formed on a plate to increase the coalescing effect of the fluid droplets, thereby improving the separation efficiency of the liqht liquid and the heavy liquid, To a separator of a plate pack type.

In general, liquid-liquid separation, especially the separation of water and oil, is considered very important in chemical processes. This is because it greatly influences the design and operation of the downstream process of the chemical process. If the unwatered oil is introduced downstream, it can lead to unexpected performance degradation and corrosion of the equipment in the downstream process.

In a conventional separator for oil-water separation, a plate pack in which a plurality of plates are arranged at an angle to be inclined has been proposed. The fluid is moved to the space between the plurality of plates and separated. For example, relatively heavy liquids (including heavy liquid droplets and solid particles) are separated along the upper surface of the plate, and light liquid droplets in the fluid are separated .

However, in the case of the conventional separator, since the fluid is separated only by the specific gravity of the fluid while moving between the platelets, separation between the heavy liquid and the light liquid may not be properly performed, Performance may be degraded.

Accordingly, there is a need for a method for improving the effect of combining droplets of a fluid to improve the water separation performance.

FIG.

1 to 3, a plate pack type separator 10 for separating a multiphase fluid of a vessel according to an embodiment of the present invention includes a support frame 100 for providing a mounting space, 220 may be provided.

Specifically, the support frame 100 can be assembled in the form of a square frame to provide a mounting space for mounting the plurality of plates 210 inward. In the present embodiment, the support frame 100 is provided in the form of a square frame for supporting a plurality of plates 210, but is not limited thereto, and the support frame 100 may stably support the plurality of plates 210 May be provided in various forms. For example, the support frame 100 may be provided in a cylindrical or hemispherical shape.

The support frame 100 may be assembled by inserting a plurality of plates 210 therein. To this end, a mounting groove (not shown) may be formed in the support frame 100 to receive the end of the plate 210. A plurality of plates 210 are vertically spaced from each other in the support frame 100 and another plurality of plates 210 are disposed apart from each other so as to be laterally symmetrical with the plurality of plates 210 . Accordingly, a flow passage for moving the liquid between the plurality of plates 210 can be formed in the inner space of the support frame 100.

The support frame 100 may be disposed continuously in the lateral direction of a vessel described later. Of course, depending on the shape / shape of the vessel, the support frame 100 may be arranged continuously in the vertical direction.

The plurality of plates 210 includes a plurality of first plates 211 spaced vertically so as to be inclined at a predetermined angle (for example, +30 to +60 degrees) in one direction in the mounting space of the support frame 100 A plurality of second plates 212 spaced apart from each other in the vertical direction by a predetermined angle (for example, -30 ° to -60 °) in the other direction in the mounting space so as to be symmetrical with the first plate 211 in the left- Lt; / RTI > For example, the first plate 211 and the second plate 212 may be provided in the mounting space of the support frame 100 in a "V"

The first plate 211 and the second plate 212 are disposed in the mounting space of the support frame 100 in the form of a plate assembly 200 that is alternately (alternately) .

Accordingly, the fluid can be moved upward or downward in the space between the first plate 211 and the second plate 212.

The flow path is constituted by a first flow path W1 formed between a plurality of plates 210 facing each other in the up and down direction and a first flow path W2 between upper and lower ends of adjacent plates 210 (first plate 211 and second plate 212) And a third flow path W3 formed in the vertical direction between the lower end of the adjacent plate 210 (the first plate 211 and the second plate 212) .

At this time, a flow of heavy liquid (including solid particles) such as water in the fluid may be formed on the lower side of the first flow path W1. On the upper side of the first flow path W1, A light liquid flow such as oil can be formed. The heavy liquid is moved downward along the inclined surface of the plate 210 on the lower side of the first flow path W1 or in other words on the upper surface of the plate 210 and flows through the third flow path W3 to the lower side of the support frame 100 Direction. The light liquid is moved upward on the upper side of the first flow path W1 or in other words on the lower surface of the plate 210 in the inclined upward direction of the plate 210 and is guided through the first flow path W1 to the upper surface of the support frame 100 Direction.

FIG. 4 is a side view showing a plate of a plate pack type separator according to an embodiment of the present invention, and FIG. 5 is a rear view of a plate viewed from a portion "B-B" of FIG.

As shown in FIGS. 4 to 5, a plurality of baffles 220 may be spaced apart from the lower surface of the plate 210. The plurality of baffles 220 increases the coalescing effect of the droplets of the fluid F, thereby maximizing the separation efficiency of the droplets. For example, a light liquid (e.g., oil) having a relatively small specific gravity out of a fluid (F: light liquid droplet, heavy liquid droplet, solid particle) flows along the first flow path W1, The light liquid grown in the baffle 220 can be moved upwardly of the plate 210 and separated from the heavy liquid.

When the plurality of baffles 220 are formed on the lower surface of the plate 210 as described above, since the write liquid rises along the lower portion of the plate 210 and grows coalescing around the baffle 220, Compared with the case where a plurality of baffles 220 are not present on the lower surface of the plate 210, the water-oil separation performance can be remarkably improved.

Here, the spacing distance d1 between the plurality of baffles 220 may be designed to be in the range of 2 to 5 times the spacing distance d2 between the plurality of plates 210. [ If the distance d1 between the plurality of baffles 220 is less than twice the distance d2 between the plurality of plates 210, the distance d1 between the plurality of baffles 220 becomes too close to each other, liquid flow can be coalesced and the combined flow of light liquids along the plate 210 can be disturbed by the baffle 220 and the distance between the baffles 220 d1 Is greater than 5 times the distance d2 between the plurality of plates 210, the separation distance d1 between the plurality of baffles 220 becomes too far away from each other, so that the effect of aggregation between droplets can be remarkably deteriorated.

The height h1 of the baffle 220 may be designed to be in the range of 0.2 to 0.3 times the distance d2 between the plurality of plates 210. [ If the height h1 of the baffle 220 is less than 0.2 times the distance d2 between the plates 210, the height h1 of the baffle 220 is too low, And the height h1 of the baffle 220 is too high when the height h1 of the baffle 220 is greater than 0.3 times the distance d2 between the plates 210, Lt; / RTI >

In this embodiment, the length of the baffle 220 can be designed to be 150 to 700 mm, more preferably 200 to 450 mm, and the spacing between the baffles 220 is designed to be 50 to 100 mm, So that they can escape from the baffle and ascend along plate 210. The length and spacing of the baffle 220 may vary according to the length and size of the plate assembly 200, and the like.
