The present invention relates to a contaminant purification apparatus, and more particularly, is installed on a path through which contaminated water moves, so that a large density of particulate contaminants can be separated by centrifugal force and gravity, and suspended solids can be separated through a shielding membrane. Related to.

In general, if the pollutants are classified according to the cause of occurrence, they can be classified into point pollutants and nonpoint pollutants. Among them, non-point sources are vehicle exhaust gases, tires, etc. which are wrapped on the surface of roads and bridges. It is a pollutant that does not have a discharge port as it causes water pollution when it enters a river through rainwater during rainy weather, such as fine dust or pollutants accumulated on the surface of a golf course, parking lot, farmland, and construction site. Since these non-point pollutants are swept away by rain, there are various kinds of pollutants with different physical and chemical properties. In order to effectively purify the polluted water, the physical chemicals of each pollutant mixed in the polluted water are mixed. Step by step separation using properties is necessary. At this time, each step is equipped with a pollutant purification apparatus for the type of pollutant to be separated.

Among such contaminant purification devices are oil / water separators that can separate suspended solids (oil, styrofoam, etc.) with less density than water. An example of such an oil / water separator is an apparatus for separating pollutants that can measure a flow rate of a treatment liquid registered by the inventor of the present invention prior to the present invention on August 16, 2004 (Application No. 10-2004-0064383). (Hereinafter referred to as 'advanced technology').

According to the contaminant separating apparatus according to the prior art (hereinafter referred to as 'oil water separator') to measure the amount of the processing liquid passing through the flow measuring port to control the inlet. Because, in the early rainwater, a lot of contaminants are mixed, but in the latter rainwater, the contaminant level of contaminants is inevitably reduced. When the amount of contaminated water flowing into the oil / water separator exceeds the treatment capacity, Even contaminants that have already been separated are swept away by later storms. In particular, in case of heavy local showers or heavy rains, such as Korea, it is inevitable that it is necessary to control the inflow of contaminated water because it has a high probability of introducing contaminated water beyond the treatment capacity.

However, according to the prior art (see Patent Publication No. 464640), the hydrocyclone and the oil / water separator are connected to each other through a pipe, so that the installation is not good, and the inlet is measured by measuring the amount of the processing liquid passing through the flow measuring port. In this case, there is a problem that the contaminants that have been separated in advance have to be swept to some extent because the amount of the treated solution that has already been introduced passes through the hydrocyclone separator and the shielding membrane.

In addition, the reason why the hydrocyclone is configured in the discharge pipe is to separate the suspended solids in the hydrocyclone separator, which causes a problem in that the product manufacturability and production cost are increased.

The present invention is to solve the above problems, by placing the hydrocyclone separator and oil and water separator inside a container of a constant volume, to simplify the structure, and also to smoothly drain the polluted water according to the amount of contaminated water introduced The aim is to provide a pollutant purification system that can be used.

Contaminated water purification apparatus according to the present invention for achieving the above object, the receiving inlet is formed on one side is the inlet for contaminated water and the outlet is formed on the other side; A hydrocyclone separator provided at the inlet side of the container to rotate the introduced contaminated water to centrifuge the particulate contaminants mixed in the contaminated water and then discharge the contaminated water from which the particulate contaminants have been separated; And an oil / water separator for separating the suspended solids from the contaminated water discharged from the hydrocyclone separator to discharge the contaminated water from which the suspended solids are separated.

Here, the detector for detecting the amount of contaminated water filled in the receiving container; And a valve device for closing the inlet when the amount of the contaminated water detected by the detector is greater than or equal to a predetermined amount. It is preferable to further include.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view of a pollution correction apparatus according to an embodiment of the present invention.

Referring to FIG. 1, the pollutant purification apparatus according to the present embodiment includes a receiving container 110, a hydrocyclone separator 120, an oil / water separator 130, and the like.

The receiving cylinder 110 is formed with an inlet 111 for introducing contaminated water to one side (the left side in the drawing) and the hydrocyclone separator 120 and the oil / water separator 130 on the other side (the right side in the drawing). A discharge port 112 through which coarse polluted water is discharged is formed.

The hydrocyclone separator 120 has an inlet hole 121 for introducing contaminated water in a tangential direction to the wall surface of the cylindrical chamber 125 and a discharge hole 122 discharged after the particulate contaminants are centrifuged. In the hydrocyclone separator according to the technology disclosed in the registration number 10-0479717, the inventors of the present invention selected and registered the application, the discharge pipe (not shown) for discharging the contaminated water collected through the central hole of the chamber through the discharge hole 122 In addition, in the hydrocyclone separator 120 of the pollutant purification apparatus according to the present invention, since the oil / water separator 130 is installed at the next stage, the discharge pipe may be removed. Therefore, the structure of the hydrocyclone separator can be simpler. In addition, the upper portion of the hydrocyclone separator 120 is formed with a removal port 123 for removing the contaminants settled on the bottom of the chamber 125 by a pump or the like.

The oil / water separator 130 is a separator 133 in which the contaminated water passage 131 is formed, and is coupled to the separator 133 in a direction facing the hydrocyclone separator 120 to contaminate the water passage of the separator 133. Shield 131, but the lower end includes a shield 132 and the like to maintain a predetermined distance from the bottom of the container 110. Therefore, the suspended solids of small density is caught by the shield 132, the remaining contaminated water passes between the bottom of the shield 132 and the bottom of the receiving container 110, the contaminated water passage 131 and the outlet 112 It can be discharged past.

The operation of the pollutant purification apparatus configured as described above will be described with reference to the operation state diagram of FIG.

After the contaminated water flows into the inlet 111 and enters the hydrocyclone separator 120, the contaminated water rotates in the hydrocyclone separator 120, whereby the particulate contaminants mixed in the contaminated water (higher density than water). This centrifugation causes it to sink downward by gravity. The contaminated water from which such particulate contaminants are separated is discharged to the outside of the hydrocyclone separator 120 (to the inside of the container and to the front end of the oil / water separator) through the discharge hole 122, wherein the hydrocyclone separator 120 ) Between the oil and water separator 130 and the surface of the contaminated water floats liquid or particulate contaminants having a smaller density than water. Therefore, contaminants having a smaller density than water are blocked by the shield 132 so that the flow path is no longer separated, and the contaminated water from which the contaminants are separated is separated between the bottom of the shield 132 and the bottom of the container 110. It is discharged through the contaminated water passage 131 and the outlet 112. However, since the hydrocyclone separator 120 according to the present invention does not constitute a separate discharge pipe and constitutes only the discharge hole 122, a part of the contaminated water that was rotated in the hydrocyclone separator 120 is sufficiently filled with particulate contaminants. Although it may be discharged to the discharge hole 122 in a non-separated state, even in such a case, since the particulate contaminants are precipitated between the hydrocyclone separator 120 and the oil / water separator 130, the polluted water may be discharged without forming a discharge pipe. It is possible to sufficiently separate particulate contaminants.

As described above, in the hydrocyclone separator 120, the particulate matter may be separated by centrifugal force, and in the oil / water separator 130, the polluted water may be separated more effectively by separating the suspended matter having a small density. Of course, the particulate matter precipitated at the bottom of the hydrocyclone separator 120 may be removed later by a pump or the like, and the suspended solids blocked by the oil / water separator 130 may be removed afterwards.

On the other hand, Figures 3 and 4 is a view for explaining a pollution correction apparatus according to two other embodiments of the present invention. 3 and 4, the contaminant purification apparatus shown in FIG. 3 is capable of effectively draining or blocking the contaminated water more than the proper capacity.

First, the pollutant purification apparatus illustrated in FIG. 3 has an excess water discharge hole 224 formed at a position higher than the discharge hole 222 formed in the hydrocyclone separator 220. Excess water discharge hole 224 is to prepare the contaminated water more than the proper treatment capacity into the inside of the hydrocyclone separator 220, when the excessive amount of contaminated water comes in due to heavy rain or heavy rain, that is, the discharge hole (222) When the contaminated water is introduced through the inlet hole 121 at a speed higher than the rate at which the contaminated water is discharged through), the water level inside the hydrocyclone separator 220 is rapidly increased. At this time, when the inner space of the hydrocyclone separator 220 is full, there is a risk that the contaminated water flows back, the excess water discharge hole 224 serves to prevent the water level to be so high. That is, in the contaminant purification apparatus according to another embodiment of the present invention shown in FIG. 3, by further forming the excess water discharge hole 224 in the hydrocyclone separator 220, it is possible to prevent the reverse flow of excess water.

On the other hand, reference numeral 223 is a removal port for removing the contaminants deposited on the bottom of the hydrocyclone separator 120.

Another embodiment for preparing the inflow of contaminated water over the treatment capacity may be the contaminant purification apparatus shown in FIG. 4. As shown in FIG. 4, the contaminant purification apparatus according to another embodiment of the present invention includes a hydrocyclone separator 120, an oil / water separator 130, a detector 340, and a valve device 350.

Since the hydrocyclone separator 120 and the oil / water separator 130 have been described in detail above, redundant descriptions are to be avoided.

The detector 340 detects the amount of contaminated water filled in the container 110 (which may be implemented by detecting the level of the contaminated water). The detector 340 may be installed anywhere inside the receiving container 110, but is installed between the hydrocyclone separator 120 and the oil / water separator 130 to pass through the oil / water separator 130 from the hydrocyclone separator 120. This is more desirable because it can accurately detect the amount of contaminated water in the process.

The valve device 350 is installed at the front end of the inlet 311 and in front of the hydrocyclone separator 120 (that is, installed inside the container), so that the amount of contaminated water detected by the detector 340 is greater than or equal to a predetermined amount. The inlet 311 is closed. Of course, depending on the application, a partial closure of the oil inlet 311 may also be considered, and if the amount of contaminated water detected by the detector 340 is again below a certain amount, the inlet 311 may be opened (of course). In addition, the valve device may include a control means for controlling the inlet by determining the amount of contaminated water detected by the detector). Of course, it may also be considered that the valve device is installed outside the receiving container.

Referring to the operation of the pollutant purification apparatus according to another embodiment of the present invention as follows.

If the contaminated water flows into the inlet 311 in the state in which the valve device 350 opens the inlet 311, and enters the hydrocyclone separator 120 through the inlet hole 321, the contaminated water is the hydrocyclone separator 120. It is rotated at, whereby the particulate contaminants (which are denser than water) mixed in the contaminated water are centrifuged and sink downward by gravity. The contaminated water from which such particulate contaminants are separated is discharged to the outside of the hydrocyclone separator 120 (to the inside of the container and to the front end of the oil / water separator) through the discharge hole 122, wherein the hydrocyclone separator 120 ) Between the oil and water separator 130 and the surface of the contaminated water floats liquid or particulate contaminants having a smaller density than water. Therefore, contaminants having a smaller density than water are blocked by the shield 132 so that the flow path is no longer separated, and the contaminated water from which the contaminants are separated is separated between the bottom of the shield 132 and the bottom of the container 110. It is discharged through the contaminated water passage 131 and the outlet 112.

On the other hand, the detector 340 continuously detects the amount of contaminated water contained in the receiving container 110, the inflow of the contaminated water increases, the amount of contaminated water contained in the receiving container 110 increases at any point in time When the predetermined amount or more, the valve device 350 is operated to block the inlet 311 to prevent the contaminated water from entering the pollutant purification apparatus. Therefore, the inlet 311 may be blocked before the pollutant previously separated by the contaminated water is swept away. At this time, the contaminated water is preferably bypassed at the front end of the contaminant purification apparatus to select a path to the rear end of the contaminant purification apparatus.

Of course, the particulate matter precipitated at the bottom of the hydrocyclone separator 120 may be removed later by a pump or the like, and the suspended solids blocked by the oil / water separator 130 may be removed afterwards.

As described above, the detailed description of the present invention has been made by the embodiments with reference to the accompanying drawings, but the above-described embodiments are only described with reference to the preferred examples of the present invention, and thus the present invention is limited to the above embodiments. It should not be understood as. Therefore, in addition to the above description, a person having ordinary knowledge in the technical field to which the present invention pertains may easily implement the present invention in another form within the same scope as the above embodiments, or by simply describing the embodiments of the present invention. It will be possible to practice the invention in the same and equal area.

As described in detail above, according to the present invention, by integrally installing the hydrocyclone separator and the oil / water separator, the structure can be simplified, resulting in improved installability and reduced production cost. In addition, it is possible to prevent the contaminated water from being swept together by the excessive inflow of contaminants because the contaminated water can be intercepted by detecting the capacity of the contaminated water before the contaminated water exceeds the treatment capacity. It has an effect.
