DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. Even if the terms are the same, it is to be noted that when the portions to be displayed differ, the reference signs do not coincide.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

1 is an overall schematic diagram of a rainwater-heavy water treatment system according to an embodiment of the present invention.

In this case, a storage tank 100 storing heavy water such as rainwater or domestic sewage is disposed. The heavy water stored in the storage tank may be used to remove odors or pathogens by using a separate acid decomposition apparatus 150 provided outside the storage tank.

The heavy water stored in the storage tank 100 can be recycled through a separate multi-step process if necessary. That is, heavy water discharged from the storage tank is removed through a high-boiling foreign material removing device 200 (or simply referred to as a foreign material removing device) that removes a relatively large foreign material having a specific gravity of about 1 or more. In the present specification, the term "high aspect ratio" means a foreign matter having a specific gravity greater than one.

Thereafter, the heavy water is removed again from the screen device 300 by removing light foreign matter having a specific gravity of 1 or less from the filter 400, removing minute foreign matters of 1 μm or less from the filter 400, and sterilizing and disinfecting the sterilizing and disinfecting device 500 And then recycled.

The present invention relates to a foreign matter removing apparatus (200) for removing a relatively large foreign matter having a specific gravity of about 1 or more in the constitution of such a heavy water recycling system.

2 is a perspective view of a foreign matter processing apparatus for removing foreign matter, which is a constitution of a heavy water treatment system according to the present invention.

Referring to FIG. 2, the foreign object processing apparatus 200 has a cylindrical body 210 capable of receiving heavy water therein and an inclined portion 215 formed in a conical shape at a lower end of the body. An inlet pipe 220 for introducing heavy water from the outside is disposed on the upper side of the body 210 and a discharge pipe 230 for discharging heavy water from which the foreign substance is removed to the outside is disposed in the center portion of the body 210. . And one end of the discharge tube is positioned approximately at the center of the body 210. The heavy water flowing into the body portion from the inflow pipe 220 is formed to flow obliquely to the inner side surface of the body portion. That is, in order that the direction of the heavy water discharged from the inflow pipe 220 is not directed toward the center of the cylindrical body, the flow direction of the water discharged from the inflow pipe is spaced by a predetermined distance d from the center of the body (C in FIG. 2) (See FIG. 3).

This is to allow the heavy water flowing into the body part to swirl in a spiral flow along the inner side wall of the body part. This can be effectively accomplished by centrifugal force and centripetal force generated in the course of flowing in a helical shape as shown by an arrow in FIG. 2, will be.

In the present invention, the swirler 240 is disposed inside the body 210 to further accelerate swirling of the flowing heavy water. The swirler 240 is in the shape of a disk having a certain thickness up and down, and its side face is disposed in contact with the inner wall of the body portion, and the body portion is vertically divided by the swirler. However, the side surface of the swash plate may be configured such that the side surface of the swash plate does not abut the inner wall of the body as a whole but only a certain portion thereof.

A center hole 241 through which the discharge pipe 230 is inserted is formed at the center of the swash plate 240 and a slope is formed at the substantially outer side of the swash plate to guide the heavy water on the swash plate A plurality of holes 243 are formed.

The inclined holes 243 penetrate the upper and lower surfaces of the swash plate 240 and are formed so as to be inclined to conform to the flow of the spiral flowing water. That is, the inclined holes are inclined obliquely (i.e., downwardly inclined) in the circumferential direction of the swash plate (see FIG. 5). The water flowing into the body 210 from the inlet pipe 220 moves downward while flowing in a helical flow and the water flowing in a helical manner flows into the inclined holes 243 of the swash plate 240 The spiral flow of the heavy water is further strengthened due to the inclination of the inclined hole in the course of entering the swath plate and flowing down the body portion.

The water is swirled by the centrifugal force generated from the water pressure in the process of flowing the heavy water inputted through the inlet pipe at a certain water pressure or higher through the inlet pipe and flows toward the side wall of the cylindrical body part while flowing toward the outside, Foreign matter foreign matter having a specific gravity of 1 or more due to the centrifugal force acts more toward the outside. That is, the foreign matter moves from the near side to the downside inside the side wall of the body part by the centrifugal force.

The apparatus for removing foreign materials according to the present invention includes an inclined portion 250 below the body 210. The inclined portion 250 has a conical shape with a narrow width at the bottom and an inclined surface inclined downwardly at its inner side. Foreign matter having a large specific gravity which makes a helical inclined flow through the swash plate moves downward along the inclined surface of the inclined portion and collects at the lowermost end.

The backflow prevention cap 250 is disposed on the inclined portion 250 of the body 210. The backflow prevention cap 250 serves to prevent the foreign substances collected at the lower end of the inclined portion from moving upward, and has a hollow cylindrical lower cylindrical portion 251 and a disk- And an upper plate 255. A plurality of first through holes 253 are formed in the bottom cylindrical portion 251 of the backflow prevention cap so that water can be introduced into the side walls of the bottomed cylindrical portion 251. A second through hole 257 is formed in the upper plate 255 in a vertical direction so that water in the lower cylindrical portion 251 flows above the upper plate.

The water passes through the first through hole 253 and the second through hole 257 and flows into the center portion of the body 210 through the first through hole 253 and the second through hole 257. [ The foreign matter having a specific gravity of 1 or more is discharged to the outside through the discharge duct formed at the lowermost end of the inclined portion. A valve 280 for opening and closing the exhaust duct is provided, and the valve can be automatically opened when a predetermined time elapses, or manually opened by an operator.

According to the above-described principle, a foreign matter processing apparatus (or a high-boiling foreign matter processing apparatus) for heavy water recycling according to the present invention is capable of selectively discharging foreign matter having a large specific gravity out of heavy water, The removed water is discharged to the outside through one end of the discharge pipe 230 which is approximately in the center. Accordingly, foreign matter having a relatively large specific gravity is removed from the heavy water discharged to the discharge pipe 230.

Thereafter, the water discharged from the discharge pipe is removed again from the screen device 300, and then the filter 400 removes minute foreign substances, and the sterilizing and disinfecting device 500 disinfects And then recycled.
