DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily carry out the present invention.

1 is a schematic diagram of a rainwater reuse apparatus according to an embodiment of the present invention. 2 is a conceptual diagram of a rainwater reuse apparatus according to an embodiment of the present invention. 3 is an enlarged view of a portion A in Fig. 4 is an enlarged view of a portion B in Fig.

1 to 4, a rainwater reuse apparatus 100 according to an embodiment of the present invention includes an inclined screen 110, a primary treatment water tank 120, a pressure pipe 130, a wind turbine 140, A car treatment bath 150, a membrane 160, and a treatment bath 170. [

The inclined screen 110 may be formed at a relatively high position. The inclined screen 110 is installed on the roof of the building or the like, and rainwater can be temporarily stored temporarily when the rainfall 10 falls.

The inclined screen 110 may include a first region 111 for storing rainwater, and a second region 112 connected to the first region 111 to receive rainwater.

The first region 111 moves the rainwater along the inclined surface 111a formed therein. Accordingly, the rainwater can be moved to one side of the first region. The rainwater is moved to the second area 112 and the first treatment water tank 120 through the drain pipes 111d and 111e connected to the drain holes 111b and 111c formed at one side of the first area 111, .

The second region 112 may receive rainwater from the drain hole 111b of the first region 111 through the pipe 111d. The second region 112 may also have an inclined surface 112a and may be moved to one side of the second region 112 along the rainwater. The second region 112 may transmit rainwater to the primary treatment water tank 120 through a drain pipe 112c connected to the drain hole 112c formed at the one side.

In this case, the first region 111 and the second region 112 can drain the initial rainfall component in the rainwater through the opening and closing operation of the valve coupled to the drain holes 111b, 111c and 112b. In the early days of rainwater collection, various pollutants may be contained in rainwater.

For example, when the rain 10 starts to fall, the initial rainfall is transmitted only to the second region 112 through the opening and closing operations of the drain holes 111d and 111e of the first region 111, It may not be delivered to the treatment water tank 120. In addition, the second region 112 can perform an operation of discharging the initial rainfall to the outside through the drainage system provided therein, and after the initial rainfall, rainwater is discharged to the primary treatment water tank 120 . Therefore, the initial rainfall containing the pollutant can be drained to the outside, and only the subsequent rainwater can be delivered to the primary treatment water tank 120.

The primary treatment water tank 120 receives the rainwater from the inclined screen 110, and stores the rainwater. The primary treatment water tank 120 may be positioned at the same or relatively lower height than the inclined screen 110. When the primary treatment water tank 120 is at the same height as the inclined screen 110, the rainwater moved along the inclined surfaces 111a and 112a formed on the inclined screen 110 is supplied to the primary treatment water tank 120 Lt; / RTI > In addition, when the primary treatment water tank 120 is lower than the inclined screen 110, rainwater can be received by gravity. In addition, the primary treatment water tank 120 has drainage holes 120a on one side. The rainwater stored in the primary treatment water tank 120 can be moved through the drain hole 120a.

The pressure pipe 130 is connected to a drain hole 120a formed in the primary treatment water tank 120. [ The pressure pipe 130 may be connected to the secondary treatment water tank 150 located below the primary treatment water tank 120. The pressure pipe 130 may include a first pipe 131 through which rainwater can be moved along the direction of gravity and a second pipe 132 connected to the first pipe 131.

The first pipe 131 is formed with a first hole 131a therein so that the rainwater can be moved downward according to gravity. The end 131b of the first hole 131a gradually becomes smaller in diameter. Accordingly, the pressure of the rainwater passing through the end portion 131b along the path A shown in Fig. 3 increases. On the other hand, the first pipe 131 has a region where the diameter increases again after the end portion 131b, so that rainwater drops at a high speed. Accordingly, the pressure of the end portion 131b is locally reduced. 3, air is introduced into the first pipe 131 from the second pipe 132 by a pressure difference (negative pressure) formed through the second pipe 132 coupled to the area, .

Meanwhile, the first pipe 131 includes a second hole 131c whose diameter is reduced again. Rainwater and air can be easily mixed by the second hole 131c and moved toward the secondary treatment water tank 150. [

The second pipe 132 is coupled to the first pipe 131 in a substantially horizontal direction. The second pipe 132 is connected to allow air to pass therethrough and the second pipe 132 is connected to the second pipe 132 by a pressure difference corresponding to a difference in flow velocity of rainwater formed in the first pipe 131, So that the air moves to the first pipe 131. Therefore, power generation through the wind power generator 140 installed in the second pipe 132 can be performed.

At least one wind turbine generator 140 is installed in the second pipe 132. The turbine is driven by the air flowing along the second pipe 132 to perform power generation. Here, the configuration and operation of the wind turbine generator 140 are the same as those of a conventional wind turbine generator, and a detailed description of the operation will be omitted.

The secondary treatment water tank 150 receives a mixture of the rainwater of the primary treatment water tank 120 and the air introduced through the pressure pipe 130 through the pressure pipe 130. At this time, the rainwater or the like is supplied from the primary treatment water tank 120 to the secondary treatment water tank 150 by gravity, but the height of the secondary treatment water pool 150 is higher than that of the primary treatment water tank 120 It may be supplied by using a separate pump if necessary.

Further, the mixture passes through the membrane 160 installed in the secondary treatment water tank 150, and is then stored in the secondary treatment water tank 150. The secondary treatment water tank 50 stores the rainwater and transfers the rainwater to the ultimate treatment water tank 170 when necessary, so that the rainwater can be reused.

The rainwater stored in the secondary treatment water tank 150 may be circulated again through a pump or the like and moved to the primary treatment water tank 120 if necessary. In this case, the power produced through the wind turbine generator 140 can be used. In the process of moving the rainwater from the secondary treatment water tank 120 to the secondary treatment water tank 150, filtration and purification are repeated, It may be possible to store rainwater continuously.

The membrane 160 is installed inside the secondary treatment water tank 150. The membrane 160 may include a filtration filter made of MF / UF / NF. The membrane 160 may be a filtration membrane formed by bundling a straw-shaped hollow fiber having a hole in the fiber bundle. In addition, the mixture of the rainwater and the air is discharged to the lower portion of the filtration membrane to generate turbulence, thereby increasing the efficiency of the membrane 160.

The treatment water tank 170 is connected to the secondary treatment water tank, and can receive rainwater passing through the membrane 160 through a separate pipe. The treatment water tank 170 can be reused as drinking water or domestic water if necessary.

Hereinafter, a driving method of a rainwater reuse apparatus according to an embodiment of the present invention will be described in detail.

5 is a flowchart illustrating a method of driving a rainwater reuse apparatus according to an embodiment of the present invention.

5, a method of driving a rainwater reuse apparatus 100 according to an embodiment of the present invention includes a rainwater inflow step S1, an initial rainwater exclusion step S2, a primary treatment water tank storage step S3, (S4), a secondary treatment water storage step (S5), a filtration step (S6), a treated water storage step (S7), and a reuse step (S8). Hereinafter, each step of FIG. 5 will be described with reference to the configurations of FIG. 1 to FIG.

The rainwater inflow step S1 is a step in which rainwater is introduced into the inclined screen 110 of the rainwater reuse apparatus 100 installed on the building roof on the rain.

The initial rainfall exclusion step S2 is a step in which the initial rainwater in the rainwater is drained through the first area 111 and the second area 112 of the inclined screen 110. [ Accordingly, the pollutants contained in the initial rainfall can be discharged to the outside.

The primary treatment water tank storing step S3 is a step in which rainwater is introduced into the primary treatment water tank 120 from the inclined screen 110 and stored. In this case, the rainwater may be introduced into the primary treatment water tank 120 by gravity or an inclined surface of the inclined screen 110.

In the power generation step S4, the rainwater in the primary treatment water tank 120 is lowered to the secondary treatment water tank 150 through the pressure pipe 130, and the power generated by the wind power generator 140 in the pressure pipe 130 Is performed. A negative pressure is formed in the second pipe 132 according to the pressure difference of the rainwater passing through the first pipe 131 of the pressure pipe 130 so that the air is introduced from the outside, And transferred to the second treatment water tank 150.

In the secondary treatment water tank storing step S5, a mixture of rainwater and air is introduced into the secondary treatment water tank 150 and stored.

In the filtration step S6, a mixture of the rainwater and air is supplied to the membrane 160 of the secondary treatment water tank 150 and filtered through the filter formed on the membrane 160. [ Accordingly, the contaminants or impurities of the rainwater are filtered, and the rainwater is purified to a state suitable for reuse.

The treated water tank storing step S7 is a step in which the rainwater in the secondary treatment water tank 150 is moved to the final treated water tank and reused. In addition, the remaining rainwater that does not need to be reused may be introduced into the primary treatment water tank 120 again to produce power and to be filtered.

The reuse step S8 is a step of reusing the rainwater stored in the treatment water tank 170 by the end user, and the reuse can be used for drinking or living water according to the purpose.

As described above, the present invention is not limited to the above-described embodiments, and can be applied to the rainwater reuse apparatus according to the present invention It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
