Description

Fluid treatment system

The present invention relates to a fluid processing system, and more specifically, to a fluid processing system capable of filtering fluid supplied to a demand location in various ways.

As the standard of living improves, the number of devices installed to filter and use water in final demand areas such as homes is increasing. The above devices, which can be represented by water purifiers, etc., are configured to filter water delivered to the final destination through various routes such as pipes just before it is discharged.

Water purifiers are often provided for drinking water. In other words, the water discharged from the water purifier is mainly used for drinking by users. At this time, the water delivered to the water purifier may be mixed with various microorganisms or impurities, and the water purifier is equipped with various types of filters to filter out the microorganisms or impurities.

Recently, requirements related to the quality of water used not only for drinking but also for domestic purposes, such as showering, washing dishes, laundry, etc., are increasing. Accordingly, technologies are being developed to filter not only the water immediately before being discharged, but also the supplied water itself and then supply it to the final destination.

Meanwhile, various components provided in the water purifier to filter water, such as filters, require maintenance as the water purifier continues to be used. Generally, maintenance of the filters, etc. is performed by way of replacement.

If a home is equipped with a water purifier, the user can periodically open the water purifier to check the status of the filter. Additionally, recently, water purifiers have been configured to directly output information about the status of the filter, allowing users to easily recognize when it is time to replace the filter.

However, the device for filtering the water supplied to the final demand point described above is installed outside the final demand point, such as a home. Additionally, for reasons such as aesthetics and space utilization, the device is generally installed in a location that is not easily accessible to users.

Moreover, the above device must filter a large amount of water compared to water purifiers provided at home. Therefore, the filter provided in the device may require more frequent maintenance compared to the water purifier provided in the home. As a result, frequent replacement of filters may require a lot of time and money.

However, the bypass line disclosed in the preceding literature does not provide a method for filtering and supplying water in various forms before being supplied into the building. In other words, the bypass line disclosed in the above prior literature only discloses filters provided in a general POE type water sanitation system.

US Patent Publication No. 2013/0277294 discloses a filter system used in a POE type water purifier. Specifically, a filter system capable of supplying and filtering water through one or more filters among a plurality of filters is disclosed.

However, the filter system disclosed in the above prior literature only discloses information about forming flow paths of a plurality of filters for use in a POE type. In other words, the prior literature does not suggest a method for managing the filter system provided in the POE type water purifier.

Furthermore, the above prior literature does not suggest a method for reducing the time and cost required for maintenance by extending the replacement cycle of the filter provided for water filtration.

At this time, one or more of the various types of flow paths may pass through the filtration unit 200, be filtered, and then flow to the demand source (D). The flow path may be defined as a first inflow flow path (IF1).

Among the various types of flow paths, other flow paths may flow to the demand destination (D) without passing through the filtration unit 200. That is, the fluid flowing along the other flow path is not filtered by the filtering unit 200, but is directly supplied to the demand point D. The flow paths may be defined as a second inflow flow path (IF2) or a third inflow flow path (IF3).

The second inlet flow path (IF2) or the third inlet flow path (IF3) may be utilized when the filter unit 200 or the first pipe 410 in communication with the filter unit 200 is damaged, maintained, or replaced. You will understand.

Additionally, as described above, the fluid delivered from the water source S may flow into the first filtering unit 200a through the second communication part 222 and be discharged after cleaning the filter member 240. In addition, the fluid delivered from the water source S and filtered in the first filtration unit 200a flows into the second filtration unit 200b, and is discharged after cleaning the filtration body 210 or the membrane member 250. You can. These flow paths can be defined as cleaning flow paths (CF1, CF2).

At this time, the filtering unit 200 may include a first filtering unit 200a and a second filtering unit 200b. Accordingly, the cleaning channels CF1 and CF2 may be divided into a first cleaning channel CF1 for cleaning the first filtering unit 200a and a second cleaning channel CF2 for cleaning the second filtering unit 200b. .

Hereinafter, with reference to FIGS. 14 to 18, various flow paths formed inside the fluid processing system 10 according to an embodiment of the present invention will be described as examples.

Referring to FIG. 14 , a first inlet flow path IF1 formed inside the fluid processing system 10 is shown. The first inlet flow path IF1 is a flow path through which fluid flows to the demand source D after being filtered by the filtration unit 200, and may be a flow path formed when the fluid processing system 10 operates normally.

First, fluid flows from the water source (S) to the first pipe 410 on the upstream side. The fluid flows to the first filtering part 200a through the first cover neck part 321 of the first cover part 300a in communication with the upstream first pipe 410 and the internal space of the cover body 310 in communication therewith. enters.

At this time, the variable flow path member 330 of the first cover part 300a is maintained in the first state (S1) (see (a) of FIG. 13). Accordingly, the fluid that has reached the inner space of the cover body 310 flows into the filtering space 211 inside the first filtering unit 200a through the first communication part 221.

At this time, the first communication part 221 communicates with the remaining portion of the filtering space 211 excluding the portion occupied by the filter member 240, that is, the radially outer space of the filter member 240. Accordingly, the fluid flows radially outwardly of the filter member 240 through the first communication portion 221.

The fluid flows radially inside the filter member 240 and is filtered while passing through the hollow fiber 241. The filtered fluid flows into the internal space of the cover body 310 through the second communication part 222 and the purified water discharge part 242. At this time, the filtered fluid flows into the internal space of the cover body 310 through the second communication part 222 that communicates with the purified water discharge part 242.

The fluid filtered by the first filtering unit 200a flows through the first cover neck portion 321 of the second cover portion 300b communicating with the first pipe 410 on the midstream side and the inside of the cover body 310 communicating therewith. It enters the second filtering unit 200b through the space.

Likewise, the variable flow path member 330 of the second cover part 300b is also maintained in the first state (S1) (see (a) of FIG. 13). Accordingly, the fluid that has reached the inner space of the cover body 310 flows into the filtering space 211 inside the second filtering part 200b through the first communication part 221. At this time, it will be understood that the fluid flows into the hollow of the membrane member 250 in communication with the first communication part 221 and is filtered.

The filtered fluid flows along the hollow of the membrane member 250 and then flows into the remaining part of the filtration space 211 and then flows into the inner space of the cover body 310 through the second communication part 222.

The fluid flowing into the inner space of the cover body 310 passes through the second cover neck portion 322 and the downstream first pipe 410 connected thereto, and flows to the demand source D.

The state of the valve unit 500 in the embodiment shown in FIG. 14, that is, the embodiment in which the first inlet flow path IF1 is formed, is described as follows.

First, the flow control valve 510 blocks communication between the first pipe 410 and the third pipe 430, and controls the upstream first pipe 410 and the downstream first pipe 410 to communicate. do.

That is, the first flow path control valve 511 blocks communication between the first pipe 410 on the upstream side and the third inflow pipe 431, and the second flow path control valve 512 blocks the first pipe 410 on the downstream side. and the third outlet pipe 432 are controlled to block communication.

Additionally, the flow path opening/closing valve 520 is controlled to close the fourth pipe 440 and block communication between the first pipe 410 and the second pipe 420. That is, the first flow path opening/closing valve 521 closes the fourth inlet pipe 441, and the second flow path opening/closing valve 522 closes the fourth outlet pipe 442.

The filtration valve 540 opens the first pipe 410 on the midstream side to communicate with the first filtration unit 200a and the second filtration unit 200b. At this time, the discharge valve 530 closes the discharge pipe 450 to block communication between the filtering unit 200 through which fluid flows and the water storage tank (R).

Referring to FIG. 15 , a second inlet flow path IF2 formed inside the fluid processing system 10 is shown. The second inlet flow path IF2 is formed to supply fluid by bypassing the filter unit 200 or the cover unit 300 when maintenance or replacement is required or when a part of the first pipe 410 is damaged. .

First, fluid flows from the water source (S) to the first pipe 410 on the upstream side. The fluid passes through the third inflow pipe 431 that communicates with the first pipe 410 on the upstream side and flows into the second pipe 420. That is, in the second inlet flow path IF2, fluid does not flow to the filtering unit 200.

The fluid flows along the second pipe 420, passes through the third outlet pipe 432, and flows into the first pipe 410 on the downstream side that is in communication with it. The fluid passes through the end of the first pipe 410 on the downstream side and is supplied to the demand point (D).

At this time, the variable flow path member 330 may be maintained in the first state (S1) or the second state (S2) (see FIG. 13). That is, since the second inlet flow path IF2 does not pass through the cover part 300 and the filtering part 200, the state of the variable flow path member 330 may be any.

The state of the valve unit 500 in the embodiment shown in FIG. 15, that is, the embodiment in which the second inlet flow path IF2 is formed, is described as follows.

First, the flow control valve 510 is controlled to communicate with the first pipe 410 and the third pipe 430 and to block communication between the first pipe 410 and the cover portion 300.

That is, the first flow control valve 511 communicates with the first pipe 410 on the upstream side and the third inlet pipe 431, but the first pipe 410 on the upstream side and the cover part 300 are blocked from communication. It is controlled. In addition, the second flow control valve 512 communicates with the downstream first pipe 410 and the third outlet pipe 432, but blocks communication between the downstream first pipe 410 and the cover portion 300. It is controlled.

Additionally, the flow path opening/closing valve 520 is controlled to close the fourth pipe 440 and block communication between the first pipe 410 and the second pipe 420.

That is, the first flow path opening/closing valve 521 closes the fourth inlet pipe 441, and the second flow path opening/closing valve 522 closes the fourth outlet pipe 442. Accordingly, it will be understood that communication between the first pipe 410 and the second pipe 420 is formed by the third pipe 430.

At this time, the discharge valve 530 closes the discharge pipe 450 to block communication between the filtering unit 200 through which fluid flows and the water storage tank (R).

Referring to FIG. 16, a third inlet flow path IF3 formed inside the fluid processing system 10 is shown. The third inlet flow path IF3 is formed to supply fluid by bypassing the filter unit 200 or the cover unit 300 when maintenance or replacement is required or when a part of the first pipe 410 is damaged. .

The practical benefit of distinguishing between the third inlet flow path IF3 and the second inflow flow path IF2 is that it can be applied even when maintenance of the third pipe 430 is required in the case of the third inflow flow path IF3.

That is, in the case of the third inlet flow path (IF3), it is formed to pass through the fourth pipe 440 located at the outermost side, and is connected to the filter unit 200, the cover unit 300, the first pipe 410, or the third pipe. Even when maintenance, etc. of 430 is required, fluid can be supplied to the demand point D.

First, fluid flows from the water source (S) to the first pipe 410 on the upstream side. The fluid passes through the fourth inlet pipe 441 that communicates with the first pipe 410 on the upstream side and flows into the second pipe 420. That is, in the third inlet flow path IF3, fluid does not flow to the filtering unit 200 or the third pipe 430.

The fluid flows along the second pipe 420, passes through the fourth outlet pipe 442, and flows into the first pipe 410 on the downstream side that communicates with it. The fluid passes through the end of the first pipe 410 on the downstream side and is supplied to the demand point (D).

At this time, the variable flow path member 330 may be maintained in the first state (S1) or the second state (S2) (see FIG. 13). That is, since the third inlet flow path IF3 also does not pass through the cover part 300 and the filtering part 200, the state of the variable flow path member 330 may be any.

The state of the valve unit 500 in the embodiment shown in FIG. 16, that is, the embodiment in which the third inlet flow passage IF3 is formed, is described as follows.

First, the flow control valve 510 is controlled to block the first pipe 410 and the third pipe 430.

That is, the first flow control valve 511 communicates with the upstream first pipe 410 and the cover part 300, but communication between the upstream first pipe 410 and the third inlet pipe 431 is blocked. It is controlled. In addition, the second flow path control valve 512 communicates with the downstream first pipe 410 and the cover part 300, but blocks communication between the downstream first pipe 410 and the third outlet pipe 432. It is controlled.

Additionally, the flow path opening/closing valve 520 is controlled to open the fourth pipe 440 and communicate with the first pipe 410 and the second pipe 420. That is, the first flow path opening/closing valve 521 opens the fourth inlet pipe 441, and the second flow path opening/closing valve 522 opens the fourth outlet pipe 442. Accordingly, it will be understood that communication between the first pipe 410 and the second pipe 420 is formed by the fourth pipe 440.

At this time, the discharge valve 530 closes the discharge pipe 450 to block communication between the filtering unit 200 through which fluid flows and the water storage tank (R).

According to the first inlet flow path IF1 formed in the fluid processing system 10 described above, the fluid from the water source S can be filtered by the filter 200 and then supplied to the demand source D. Accordingly, the cleanliness of the fluid supplied to the demand D can be improved, and the user's satisfaction can also be increased.

When maintenance of the filter unit 200 or the cover unit 300 is required, fluid cannot be supplied to the demand point D along the first inlet flow path IF1. In this case, even if the fluid is not filtered by the filtering unit 200, it is most important to supply the fluid to the demand location D.

Accordingly, in the above case, a second inlet flow path (IF2) or a third inlet flow path (IF3) is formed inside the fluid processing system 10, so that the fluid can flow to the demand source (D). Accordingly, fluid can be supplied to the demand location D regardless of the maintenance status of the filter unit 200 or the cover unit 300, thereby increasing user convenience.

17 to 18, cleaning flow paths CF1 and CF2 formed inside the fluid processing system 10 are shown. The cleaning flow paths CF1 and CF2 are flow paths through which the filter member 240 or the membrane member 250 can be cleaned by the fluid by changing the path through which the fluid flows into the filtering unit 200.

When the cleaning channels CF1 and CF2 are formed, the fluid flowing into the filter unit 200 cleans the filter member 240 or the membrane member 250 and is in a contaminated state, so it is not supplied to the demand destination D. desirable. Accordingly, the cleaning channels CF1 and CF2 are formed to include a discharge pipe 450, so that the contaminated fluid can be discharged into the water storage tank R.

Referring to FIG. 17 , a first cleaning flow path CF1 formed inside the fluid processing system 10 is shown. The first cleaning flow path CF1 is formed so that the fluid supplied from the water source S is discharged after cleaning the first filtering unit 200a.

First, fluid flows from the water source (S) to the first pipe 410 on the upstream side. Fluid enters the first filtering unit 200a through the internal space of the first cover neck 321 in communication with the upstream first pipe 410 and the cover body 310 in communication therewith.

At this time, the variable flow path member 330 is maintained in the second state (S2) (see (b) of FIG. 13). That is, the first communication part 221 is closed by the wing part 332 of the variable flow path member 330. Accordingly, the fluid that has reached the inner space of the cover body 310 flows into the filtering space 211 inside the filtering unit 200 through the second communication part 222.

At this time, the second communication part 222 communicates with the purified water discharge part 242 of the filter member 240. Accordingly, the fluid flows radially inside the filter member 240 through the second communication portion 222.

The fluid flows radially outward of the filter member 240 and passes through the hollow fiber 241, separating foreign substances accumulated in the hollow fiber 241. The flowing fluid and foreign substances flow toward the first discharge pipe 451 along the extension direction of the filter member 240. Fluid and foreign matter may pass through the discharge pipe 450 and flow into the water storage tank (R).

Additionally, the flow path opening/closing valve 520 is controlled to close the fourth pipe 440 and block communication between the first pipe 410 and the second pipe 420. That is, the first flow path opening/closing valve 521 closes the fourth inlet pipe 441, and the second flow path opening/closing valve 522 closes the fourth outlet pipe 442.

The filtration valve 540 opens the first pipe 410 on the midstream side to communicate with the first filtration unit 200a and the second filtration unit 200b. At this time, the first discharge valve 531 closes the discharge pipe 450 to block communication between the first filter 200a through which the fluid flows and the water storage tank (R), and the second discharge valve 532 closes the discharge pipe 450. 2 Open the discharge pipe 452 to communicate with the second filter unit 200b and the water storage tank R.
