Description

Oil-water separator The present invention relates to an oil-water separator, and more specifically, to an oil-water separator with an improved structure that can increase the separation efficiency between water and an oil component, including napralene oil, which is a byproduct generated during the coke production process. An oil-water separator is intended to separate oil components from water. Since oil components such as naphthalene oil are obtained as byproducts during the coke production process, it is an essential facility that must be constructed to separate these oil components from water. In such oil-water separators, a separation tank is provided to separate the oil components and water introduced into the interior using an overflow method based on the difference in specific gravity. However, in existing separation tanks, when the pressure of the fluid entering the interior (oil with a boiling point of 0.70 to 0.80 specific gravity + naphthalene oil + water) is high and the inflow speed is fast, there is a problem in that the separation time is insufficient, so the water also overflows along with the oil components with lower specific gravity, rather than just the oil components. FIG. 1 is a cross-sectional view of an oil-water separator according to an embodiment of the present invention. FIG. 2 is a perspective view of a barrier member employed in one embodiment of the present invention. FIG. 3 is a cross-sectional view of an oil-water separator according to another embodiment of the present invention. FIG. 4 is a drawing for explaining the operation of another embodiment of the present invention. FIG. 5 is a block diagram relating to the control flow of an embodiment of the present invention. In order to clarify the understanding of the present invention in the following description, descriptions of known technologies regarding the features of the present invention will be omitted. The following embodiments are detailed descriptions to aid in understanding the present invention and are not intended to limit the scope of the rights of the present invention. Accordingly, equivalent inventions that perform the same function as the present invention will also fall within the scope of the rights of the present invention. Furthermore, in the following description, identical identification symbols denote identical configurations, and unnecessary redundant descriptions and descriptions of known technologies are omitted. Additionally, descriptions of each embodiment of the present invention below that overlap with the description of the technology forming the background of the invention are also omitted. Hereinafter, an oil-water separator according to an embodiment of the present invention will be described in detail with reference to the attached drawings. FIG. 1 is a cross-sectional view of an oil-water separator according to an embodiment of the present invention, and FIG. 2 is a perspective view of a barrier member employed in an embodiment of the present invention. As illustrated in these drawings, an oil-water separator according to one embodiment of the present invention is intended to separate oil and water generated during the product manufacturing process at an industrial site and comprises a separation tank (1) and a barrier member (3). The above separation tank (1) is provided with a receiving space for receiving fluid, and a partitioning unit (2) is installed to partition the receiving space into an interface compartment (A) and an oil compartment (B). Here, the partitioning unit (2) is installed upright along the vertical direction, with the upper surface and the inner surface facing the separation tank (1) being open, so that due to the difference in specific gravity between oil and water, the oil present in the upper layer of the water in the interface compartment (A) flows over into the oil compartment (B) through the open gap. This separation tank (1) includes at least one inlet pipe (C) installed to be connected to an inlet line of water and an oil component including naphthalene oil generated during the coke manufacturing process, so that the oil component and water are introduced into the interface chamber (A) through the inlet pipe (C). If only the partition unit (2) exists within the separation tank (1), as in the prior art, when the pressure of the fluid flowing in through the inlet pipe (C) is high and the inflow speed is fast, the probability of water flowing into the oil compartment (B) along with the oil components increases. To solve this problem, the present invention includes a barrier member (3) that is provided separately from the partition unit (2) and organically combined with the partition unit (2) to suppress the overflow of water. That is, the above-mentioned barrier member (3) is installed in the interface compartment (A) so that the interface compartment (A) is divided vertically and a plurality of oil discharge holes (31) are provided, so that even when a fluid
