Description

Water treatment device {WATER TREATMENT APPARATUS}

The present invention is a technique for a water treatment apparatus for filtering various foreign substances contained in raw water.

In general, water treatment refers to a treatment for removing various foreign substances, microorganisms, and the like contained in raw water by physical, chemical, and electrical methods in raw water taken for use as drinking water, industrial water, ballast water, and the like.

Chemical treatment is a method of adding a flocculant so that particulate matter contained in raw water is precipitated by flocculant. The chemical treatment method has the advantage of being able to separate and separate the very fine particles contained in the raw water by using the flocculant, but the disadvantage is that the treatment cost increases, the treatment time is long, and a large treatment space is required to settle the sludge. .

Water treatment method using membrane also has a problem of expensive treatment, and it is necessary to backwash when contaminating the membrane. It is usually time-consuming and expensive because it washes the contaminated membrane with a cleaning agent such as caustic soda. Has

On the other hand, the water treatment needs to be purified to an appropriate degree depending on the use of the treated water. In other words, if the treated water is used as drinking water, a high degree of purified water is required to be harmless to the human body. However, when the treated water is used as industrial water or used for intermediate treatment prior to final treatment, it is reasonable to treat the water only to the extent that it is met.

Excessive water treatment will cause unnecessary cost increases and reduce the efficiency of the device.

As a related art of the present invention, there is a "particle separation apparatus of a water treatment system" of Korean Patent No. 10-0452432 (registered on October 1, 2004).

As the inflow water introduced through the inlet 112a formed in the storage tank 112 of the storage tank 110 continuously passes through the first screen 120 and the second screen 130, the particulate matter contained in the inflow water is firstly formed. Only the treated water filtered through the outer surface of the screen 120 and the inner surface of the second screen 130 is discharged through the outlet 112b of the storage tank 112.

On the other hand, the sludge in the cake state remaining on the inner surface of the second screen is collected through the sludge collecting means flows into the sludge retention tank 114 to form a lower portion of the storage tank 110, accordingly the sludge retention tank 114 When the pressure difference of the) increases and the pressure difference with the upper side of the storage tank 112 is greater than or equal to the set value, the sludge inside the sludge retention tank 114 is discharged through the sludge discharge port 114a by the opening of the rinse valve 170.

When the sludge inside the sludge retention tank 114 is discharged through the sludge outlet 114a by the opening of the rinse valve 170, the back washing occurs in the second screen 130.

However, the prior art has a problem that the backwashing of the first screen located on the upper side of the second screen is not smoothly performed, and thus, there is a problem that the first screen must be disassembled and washed after use to some extent.

The prior art is not suitable for use in water treatment equipment that does not require highly purified water, but the prior art water purification equipment is not suitable for use for large-capacity water treatment. There is a problem.

2 is a block diagram of a water treatment apparatus according to a first embodiment of the present invention.

The water treatment device according to the first embodiment of the present invention may be selectively operated in a water purification process and a washing process. The water purification process is a process of separating and discharging foreign matters into the concentrated water and the treated water by filtering the foreign substances above a certain size contained in the incoming raw water. It is a process to make the water purification process more smoothly. This will be described later in more detail.

As shown, the water treatment apparatus according to the first embodiment includes a treatment chamber 100, a guiding and filtering member 200.

The processing chamber 100 is formed by separating the first space part 110 and the second space part 120.

The first space part 110 of the processing chamber 100 is provided with a raw water inlet 101 through which raw water flows, and a first open / close valve V1 is provided at the raw water inlet 101. Here, raw water corresponds to untreated fresh water, seawater or polluted water containing various foreign substances.

In addition, the other side of the processing chamber 100 is formed with a concentrated water outlet 103 for discharging the concentrated water with concentrated foreign matter. Through the brine outlet 103, the brine containing the foreign matter separated and filtered by the flow guide plate 210 and the screen member 220 is discharged.

Therefore, the raw water introduced into the raw water inlet 101 may form a first flow toward the concentrated water outlet 103 while the foreign matter is concentrated.

The second space part 120 is provided with a treated water outlet 102 through which the foreign matter is filtered. That is, the treated water is discharged through the treated water outlet 102.

Preferably, the treated water outlet 102 is provided with a second open / close valve V2, and the concentrated water outlet 103 is provided with a third open / close valve V3. In addition, it is preferable that the first pressure gauge (P1) is provided in the first space portion 110, and the second pressure gauge (P2) is provided in the second space portion (120).

Also preferably, the second space portion 120 of the treatment chamber 100 may be connected to a washing water supply line 600 for providing washing water for washing. In addition, the washing water supply line 600 is connected to the washing water supply pump 610 to supply the washing water to the second space 120 during the washing process.

The guiding and filtering member 200 is provided to divide the processing chamber 100 into the first space part 110 and the second space part 120. In FIG. 2, the guiding and filtering member 200 partially contributes to the division into the first space 110 and the second space 120, but according to an embodiment, the guiding and filtering member 200 may be used. Only by the first space portion 110 and the second space portion 120 may be distinguished from each other.

That is, in this embodiment, the partition wall 130 is provided together with the guiding and filtering member 200 to divide the internal space of the processing chamber 100 into the first space part 110 and the second space part 120. In some embodiments, the partition wall 130 may not be necessary.

In this embodiment, the guiding and filtering member 200 includes a plurality of flow guide plates 210 and a plurality of screen members 220.

The plurality of flow guide plates 210 are spaced apart in parallel to each other and are fixedly installed inside the processing chamber 100 while maintaining the separation distance from each other.

In the present embodiment, the flow guide plate 210 is illustrated in a plate shape having a predetermined thickness and length, and each flow guide plate 210 is disposed to be oriented in the same direction in parallel to each other.

In addition, in the present embodiment, since the first flow is a flow from the top to the bottom, the overall arrangement of the plurality of flow guide plates 210 is disposed along the first flow, that is, parallel or somewhat inclined with the first flow.

The flow guide plate 210 may be a straight plate, but may be modified in various forms according to the embodiment. For example, in another embodiment to be described later, the flow guide plate 210 may be configured in the form of a pipe having a reduced diameter, such as a funnel.

In particular, the arrangement of each flow guide plate 210 constituting the guiding and filtering member 200 is determined according to the direction of the first flow, and each flow guide plate 210 is reversed relative to the first flow. It is arranged to be inclined.

By the arrangement of the flow guide plate 210 in FIG. 2, the top of the flow guide plate 210 is located in the second space part 120, and the bottom of the flow guide plate 210 is located in the first space part 110. .

That is, each flow guide plate 210 in the drawing is disposed inclined upward from the left to the right.

By such a configuration, a second flow toward the second space portion 120 from the first space portion 110 is formed between the flow guide plates 210. In addition, the second flow has a direction inclined in a reverse direction with respect to the first flow.

In this way, the raw water introduced into the processing chamber 100 is divided into the first flow and the second flow, but the relatively large foreign matter contained in the first flow to the concentrated water outlet 103 along the first flow by the inertia. Tend to be discharged. That is, by inertial separation, relatively large foreign substances are separated from the raw water into concentrated water.

Meanwhile, the second flow may include a foreign material having a relatively small size, which is secondarily filtered by the screen member 220.

The screen member 220 is provided between the neighboring flow guide plate 210, the screen member 220 is provided between the two neighboring flow guide plate 210 to reduce the cross-sectional area of the flow path of the second flow to filter foreign matter Will be That is, the second flow is that foreign matter is filtered between the screen member 220 and the flow guide plate 210 while passing between the screen member 220 and the flow guide plate 210.

The distance between the screen member 220 and the flow guide plate 210 may be adjusted according to the size of the foreign material to be filtered, and an interval sufficient to filter out foreign matter of about 30 μm is sufficient.

The screen member 220 of the present embodiment is such that the thickness of the cross section decreases from one side facing the first space 110 to the other side facing the second space 120. The cross-sectional shape of the preferred screen member 220 is preferably a triangular or trapezoidal shape.

3 is a cross-sectional view showing a cross-sectional shape of the screen member that can be implemented.

That is, in the case of the screen member 220 having a triangular cross section as shown, the bottom side 221 of the triangle faces the first space part 110 and the vertex 222 faces the second space part 120. It's like that.

And more preferably, one side (bottom side) 221 of the screen member 220 facing the first space portion 110 is arranged at an oblique angle to be in a direction orthogonal to the arrangement line (L1) of the flow guide plate 210. It is desirable to.

A screen member 220 having a cross section of the screen member 220 having a trapezoidal shape may be used. The long lower side 223 is disposed toward the first space portion 110, and the shorter upper side 224 is disposed toward the second space portion 120. In addition, the screen member 220 may be used in any form as long as the thickness of the two cross-section is reduced from one side to the other side.

When the cross-sectional shape of the screen member 220 is shaped like a triangle or trapezoid, there are advantages as follows.

In the water purification process, when the small foreign matter passes through the screen member 220, the cross-sectional thickness of the screen member 220 is rapidly reduced, so a lot of space is formed at the rear part so that the small foreign matters more smoothly in the second space portion 120. Will be moved to).

On the other hand, in the case of the washing process, when the fluid moves from the second space part 120 to the first space part 110, the gap between the flow guide plate 210 and the screen member 220 gradually decreases, thereby increasing the speed of the fluid. The action can be made more smoothly.

In addition, the screen member 220 is preferably provided to be biased toward the second space portion 120 to the treatment water is generated on the basis of the center line (L2) of the flow guide plate (210). If the position of the screen member 220 is installed to be biased toward the second space part 120 with respect to the center line L2, the flow guide plate 210 and the flow guide plate 210 positioned in the first space part 110 during the water purification process. Vigorous vortex is generated by the raw water descending between the relatively large foreign matters can be prevented between the screen member 220 and the flow guide plate 210, passing through the screen member 220 to the second space portion ( Foreign material directed to 120 may be immediately mixed with the treated water and discharged.

In this way, by eccentrically positioning the position of the screen member 220 toward the second space portion 120, foreign matter can be smoothly concentrated, foreign matter of a large size between the screen member 220 and the flow guide plate 210 is easily caught. As a result, water purification efficiency can be increased.

Hereinafter, the water purification process and the washing process performed in the water treatment apparatus according to the first embodiment of the present invention will be described in detail.

First, the third open / close valve V3 is closed during the water purification process, and the first open / close valve V1 is opened to allow the raw water to flow into the first space 110. The second open / close valve V2 is also opened.

When the raw water flows into the first space portion 110, a first flow flowing toward the concentrated water outlet 103 is formed, and a second flow is formed toward the second space portion 120 by diverging from the first flow. do. That is, the raw water introduced into the first space 110 flows directly toward the concentrated water outlet 103 to form the first flow, and part of the raw water is separated from the first flow to form the second flow.

That is, the second flow is a flow formed between the plurality of flow guide plates 210, and in order to form the second flow, the plurality of flow guide plates 210 are disposed to be inclined in a reverse direction with respect to the first flow, so as to form the second flow. The second flow is inclined in the reverse direction.

The large foreign matters contained in the raw water are immediately discharged to the concentrated water outlet 103 along the first flow, and the foreign substances swept into the second flow flows toward the screen member 220 even if the specific gravity is small or the specific gravity is large. Done.

That is, by the arrangement of the flow guide plate 210, relatively large foreign matters have a tendency to match the flow of the first flow and are inertia separated firstly, and small foreign matters are secondarily filtered by the screen member 220.

The second flow toward the second space portion 120 flows through the flow guide plate 210 and the screen member 220 while flowing backward while forming an S-shape on the arrangement structure of the flow guide plate 210. Most of the foreign substances included in the second flow is filtered because it does not pass between the flow guide plate 210 and the screen member 220, only the fine foreign matters smaller than the gap between the screen member 220 and the flow guide plate 210. 2 is moved to the space 120.

In other words, the raw water flowing into the first space 110 is first flow and foreign matter having a large specific gravity by the second flow split from the first flow flows along the first flow to the concentrated water outlet 103. Some large foreign matters among the foreign matters included in the second flow which is immediately discharged and flowed back are filtered by the screen member 220 and the flow guide plate 210, so that an effective water purification action may be achieved.

When the raw water smoothly flows from the first space portion 110 to the second space portion 120 during the initial operation, the state of the concentrated water and the treated water discharged through the concentrated water outlet 103 and the treated water outlet 102 is displayed. The pressure generated in the first space 110 and the second space 120 is adjusted appropriately by adjusting the second open / close valve V2 and the third open / close valve V3.

Since the first pressure gauge P1 is connected to the first space part 110 and the second pressure gauge P2 is connected to the second space part 120, the second open / close valve V2 and the second pressure gauge P2 are connected to each other. Adjust the opening degree of the third open / close valve V3.

Since the degree of pressure formed in the first space 110 and the second space 120 also affects the filtration efficiency of the foreign matter at the time of purification, an appropriate pressure is formed in each space.

The raw water introduced into the first space 110 is divided into a first flow and a second flow, and the second flow flows through the flow guide plate 210 and the screen member 220 while being flowed back in an S shape. As some of the raw water flows backward, foreign substances having a predetermined size or more are filtered while passing between the screen member 220 and the flow guide plate 210, and the raw water containing the small foreign substances is moved to the second space part 120 to be treated.

As the water purification process proceeds, the more the foreign matter caught between the screen member 220 and the flow guide plate 210, the amount of raw water moving from the first space portion 110 to the second space portion 120 is reduced. In this case, the pressure of the first space 110 is increased and the pressure of the second space 120 is dropped. That is, the pressure value of the first pressure gauge (P1) is increased and the pressure value of the second pressure gauge (P2) is lowered. If the differential pressure between the two pressure gauges is more than a certain degree, the water purification process is not performed properly, so a washing process is required.

In the cleaning process mode, the first opening / closing valve V1 is closed so that raw water does not flow into the first space 110, and the second opening / closing valve V2 is also closed. Thereafter, the washing water supply pump 610 is operated so that the washing water flows into the second space part 120, and the washing water introduced into the second space part 120 moves toward the first space part 110.

The washing water introduced into the second space part 120 flows to the first space part 110 between the flow guide plate 210 and the screen member 220, and the screen member 220 and the flow guide plate during the water purification process. Foreign matter caught between the 210 is eliminated by the washing water is discharged through the concentrated water outlet 103 is made by washing.

The flow guide plate 200 provided in the treatment chamber 100 may be arranged in various forms according to the inflow direction of the raw water or the intended use of the water treatment apparatus.
