The present invention relates to a smart filtering system for apartments (apartment buildings) that can block the supply of contaminated tap water, and more specifically, to prevent the supply of contaminated tap water to water tanks in apartments, villas, and buildings. This relates to a smart filtering system for apartments (public buildings) that can detect the quality of tap water supplied, purify contaminants when contamination occurs, and block the supply of contaminated tap water.

In general, tap water is supplied from a local water purification plant to a reservoir, then through water pipes to a reservoir in a building, etc., and then supplied to each household as needed. In this process, secondary contamination occurs due to various factors. This can occur, and for this reason, there is an increasing trend in the number of households installing purified water instead of drinking tap water, or purchasing and drinking bottled water separately.

Therefore, various technologies are being developed to prevent secondary contamination of tap water supplied inside buildings, purify contaminated tap water, and supply clean tap water to each household. Conventional technologies for this purpose include Registered Patent Publication No. 2289164. A smart tap water filtering system for apartment water storage tanks (hereinafter referred to as 'patent document') is disclosed.

The patent document includes an apartment water storage tank that stores tap water flowing in from a local drainage reservoir through a raw water supply pipe to supply it to the apartment complex; First to third tap water quality meters installed at the front and rear ends of the water storage tank of the apartment complex and at the front end of the inflow of each household of the apartment complex; A drain pump that drains tap water remaining in the raw water supply pipe when replacing or inspecting a filter; a first valve disposed between the raw water supply pipe and the drain pump and controlling the supply of tap water flowing in through the raw water supply pipe to the drain pump; a second valve disposed between the raw water supply pipe and the apartment water storage tank, and controlling the supply of tap water from the raw water supply pipe to the apartment water storage tank; a third valve disposed on a drain side of the apartment house water tank and controlling the discharge of tap water from the apartment house water tank; a filter-type water purification device that primarily purifies and outputs tap water discharged from the water storage tank of the apartment complex through the third valve; An ultraviolet (UV) sterilization water purification device that irradiates ultraviolet rays on tap water that has been purified primarily through the filter-type water purification device to purify the water and output the water secondarily; a fourth valve and a sixth valve that control tap water discharged from the water tank of the apartment complex and passing through the third valve to bypass the filter-type water purification device and the ultraviolet (UV) sterilization water purification device; a fifth valve that regulates the supply of tap water discharged from the water storage tank of the apartment complex and passing through the third valve to the filter-type water purification device; a seventh valve controlling the supply of tap water output from the ultraviolet (UV) sterilization and water purification device to each household of the apartment complex; a water pump that pumps tap water passing through the sixth valve and the seventh valve and supplies it to each household of the apartment complex; And a valve control device that controls each opening and closing operation of the first to seventh valves by an artificial intelligence (AI) analysis algorithm according to the water quality status of tap water from the first to third tap water quality meters, The first to third tap water quality meters include: a first tap water quality meter installed at the front of the apartment water storage tank; A second tap water quality meter installed at the rear end of the apartment water storage tank; And a third tap water quality meter installed in front of the inflow of each household of the apartment complex, and measuring tap water flowing into the apartment water storage tank, tap water discharged from the apartment water storage tank, and tap water flowing into each household of the apartment building. detects the water quality status and outputs it as sensing data, detects harmful substances in the tap water and outputs them as hazardous substance data, and the valve control device detects the water quality level of the raw water is poor and the amount of tap water in the water storage tank of the apartment complex is poor. If it is sufficient above a certain standard and the water quality grade is normal, the detection result of the first tap water quality meter is unsuitable, and the detection results of the second tap water quality meter and the third tap water quality meter are suitable, the second valve , closing the fifth valve and the seventh valve, and controlling the first valve, the third valve, the fourth valve, and the sixth valve to open.

However, the above patent document measures the quality of tap water supplied to the building's water tank to determine whether to supply it to the water tank, and additionally tests the water quality before supplying it from the water tank to each household, removing contaminants if necessary before supplying it. However, in this case, when the raw water supplied to the water tank is contaminated, if the cause of the raw water contamination is not resolved, the raw water cannot be supplied to the water tank and it remains continuously blocked, so there is a problem that the tap water supply to each household may be interrupted. .

Therefore, when contamination occurs in the raw water supplied to the water tank, the contaminated raw water is purified and clean tap water is supplied to the water tank, preventing secondary contamination of tap water stored in the water tank, and the structure has been improved so that each household can continuously use tap water. Development of a tap water supply system is required.

Hereinafter, the present invention will be described in detail according to the accompanying drawings showing preferred embodiments.

The present invention provides a supply of contaminated tap water that, when the raw water supplied to the water tank of an apartment or apartment building is contaminated, can purify the raw water and supply it to the water tank, and can optimally remove contaminants by changing the type of filter depending on the factors of raw water contamination. The purpose of the present invention is to provide a smart filtering system for apartments (apartment buildings) that can block, and as shown in FIG. 1, the present invention includes a water storage tank (10), a water pump (20), a raw water filtering device (30), and an on-site It includes a control device 40, a remote control device 50, and a cloud server 60.

Hereinafter, for convenience of explanation, the upward direction will be referred to as 'upstream' and the downward direction will be referred to as 'downstream' based on the direction in which tap water flows.

The water storage tank 10 is installed in buildings such as apartments, apartments, and buildings, and tap water is supplied from the outside along the water supply system. It stores a certain amount of tap water to be supplied to each household as needed.

A raw water supply line (L1) through which raw water is supplied is installed on one side of this water storage tank (10), and a water level sensor (not shown) that detects the water level of tap water stored inside the water storage tank (10), which detects the temperature of tap water. A temperature sensor (not shown) that detects contamination of tap water and a water quality sensor (not shown) may be installed.

In addition, a first control valve (V1) is installed on the raw water supply line (L1) to open and close the flow path, and this first control valve (V1) is automatically opened and closed under the control of the field control device 40, which will be described later. It is composed.

In addition, a first water quality measurement device (S1) is installed on the raw water supply line (L1) to measure the water quality of the raw water. This first water quality measurement device (S1) is installed relatively upstream of the first control valve (V1). When the raw water is determined to be contaminated through the first water quality measuring device (S1), the first control valve (V1) located downstream is immediately blocked to prevent the contaminated raw water from being supplied to the water storage tank (10). do.

At this time, the first water quality measurement device (S1) includes a turbidity measurement sensor that measures the turbidity of the raw water and an electrical conductivity measurement sensor that measures the electrical conductivity of the raw water. Since tap water becomes turbid to that extent, the presence of particulate contaminants can be confirmed by detecting turbidity. If ionic contaminants are present, the electrical conductivity of the raw water increases, so measuring the electrical conductivity can determine the presence of ionic contaminants. This is because the presence or absence of contaminants can be confirmed.

The water pump 20 is configured to pump tap water stored in the water storage tank 10 and supply it to the user. Since the water pump 20 is appropriately selected from among various known water pump configurations, detailed description will be omitted. .

On the upstream side of this water pump 20, a water tank drain line (L2) connected to the water tank 10 is installed so that tap water discharged from the water tank 10 is supplied to the water pump 20, and the water pump 20 ), a user-side supply line (L3) is installed on the downstream side to supply tap water to the user.

And a second control valve (V2) and a third control valve (V3) are installed on the water tank drain line (L2) and the user side supply line (L3), and these second and third control valves (V2, V3) are used as field control devices. It is configured to automatically open and close under the control of (40).

In addition, a third water quality measurement sensor (S3) is installed on the water storage tank drain line (L2) or the user side supply line (L3) to measure the water quality of tap water discharged from the water storage tank (10). This third water quality measurement sensor (S3) is located upstream of the second control valve (V2) or the third control valve (V3), so that if the discharged tap water is contaminated, the second control valve (V2) or the third control valve (V3) is immediately blocked to the user. It is controlled so that tap water is not supplied.

The raw water filtering device 30 is located upstream from the water storage tank 10 where raw water is supplied and is configured to selectively purify tap water depending on whether the raw water supplied to the water storage tank 10 is contaminated.

As shown in FIG. 1, this raw water filtering device 30 has one end connected between the first water quality measurement sensor (S1) and the first valve (V1) of the raw water supply line (L1) to allow contaminated raw water to flow in. It includes a contaminated water inlet line (L4) of a predetermined length, an ionic material filter line (L5) and a particulate material filter line (L6) branching from the contaminated water inlet line (L4).

In addition, the 4th, 5th, and 6th control valves (V4, V5, and V6) that open and close the flow path are installed on the contaminated water inflow line (L4), ionic material filter line (L5), and particulate material filter line (L6), respectively. The fourth, fifth, and sixth control valves (V4, V5, and V6) are configured to automatically open and close under the control of the field control device 40 to change the flow path.

Additionally, an ionic substance filter (31) is installed in the ionic substance filter line (L5) to remove ionic contaminants contained in raw water, and the particulate substance filter line (L6) is installed to remove particulate contaminants contained in raw water. A filter to remove particulate matter is installed.

In addition, a connection line (L7) of a predetermined length connected to the particulate material filter line (L6) is installed on the downstream side of the ionic material filter 31, and the ionic material filter 31 is connected through this connection line (L7). ) may be configured to allow tap water that has passed through a particulate matter filter to remove particulate contaminants together, and a seventh control valve (V7) may be installed on the connection line (L7), and this seventh control By adjusting the opening amount of the valve V7, the flow rate of the tap water that has passed through the ionic material filter 31 into the particulate material filter is adjusted.

Meanwhile, as shown in FIG. 1, the particulate matter filter includes a primary particulate matter filter 32 that removes contaminants with a particle size of 1 μm or more, and a particulate matter filter located downstream of the primary particulate matter filter 32. It may be installed and consist of a secondary particulate filter 33 that removes contaminants with a particle size of less than 1㎛ in the water that has passed through the primary particulate filter 32, and in this case, the primary particle A connection line (L8) having a predetermined length is installed on the downstream side of the particle filter 32 and the upstream side of the secondary particulate matter filter 33, thereby allowing the tap water that has passed through the primary particulate matter filter 32 By continuously passing through the secondary particulate matter filter 33, particulate contaminants are removed twice depending on the particle size.

In this way, when the first and second particulate matter filters 32 and 33 are configured to filter the particulate matter in two stages according to particle size, the secondary particulate matter filter is filtered by contaminants with a particle size of 1㎛ or more. (33) can be prevented from being easily blocked, and as a result, a fine filter is applied to extend the service life of the secondary particulate material filter (33), which has a relatively high unit price compared to the first particulate material filter (32). Since this can be done, the operating cost of the raw water filtering device 30 is reduced.

And on the downstream side of the secondary particulate matter filter 33, a water return line (L9) of a predetermined length connected to the raw water supply line (L1) is installed, and on this return line (L9), water is supplied to the raw water supply line (L1). Before this, a second water quality measurement sensor (S2) is installed to re-measure the quality of the purified tap water to check whether contaminants have been removed.

At this time, the second water quality measurement sensor (S2) includes a turbidity measurement sensor and an electrical conductivity measurement sensor like the first water quality measurement sensor (S1), through which the turbidity and electrical conductivity of the purified tap water are measured.

In addition, an eighth control valve (V8) is installed on the water return line (L9) between the second water quality measurement sensor (S2) and the raw water supply line (L1), and the secondary particulate matter filter (33) and the third water quality measurement A return line (L10) connecting the contaminated water inflow line (L4) and the return line (L9) is installed between the sensors (S3), and a ninth control valve (V9) is installed on the return line (L10). If the water quality measured through the second water quality measurement sensor (S2) does not meet the preset standard value, instead of closing the eighth control valve (V8), the ninth control valve (V9) is opened to flow toward the raw water supply line (L1). As the purified tap water is supplied to the contaminated water inlet line (L4), the contaminants are controlled to be filtered again through the ionic material filter 31 and the first and second particulate material filters 32 and 33.

Meanwhile, a pressure sensor (not shown) is installed in the ionic material filter 31 and the particulate material filter to detect internal pressure, and the ionic material filter 31 and the particulate material filter are installed through this pressure sensor. Changes in the internal pressure of the filter may be detected in real time and transmitted to the field control device 40, which will be described later.

At this time, the field control device 40 compares the internal pressure values of the ionic material filter 31 and the particulate material filter detected in real time through the pressure sensor with a preset reference value. At this time, the measured internal pressure value is the set reference value. If it is higher, it is determined that replacement or inspection of the filter is required, and an inspection signal is transmitted to the remote control device 50.

If the raw water supplied through the raw water supply line (L1) through the raw water filtering device 30 configured as above is contaminated, the cause of contamination is classified into particulate contaminants and ionic contaminants, and then adjusted to the cause of contamination. The flow path passing through the filter is changed, thereby extending the service life of the filter and reliably removing the cause of contamination.

The field control device 40 is installed at a site near the water storage tank 10 and controls the operation of the water pump 20 and the raw water filtering device 30.

As shown in FIG. 2, this field control device 40 receives information measured from the PLC control unit 41, which controls the operation of the internal structure, and the first, second, and third water quality measurement sensors (S1, S2, and S3). The sensor communication unit 42 receives the information, the valve communication unit 43 controls the opening and closing operations of the first to ninth control valves (V1 to V9), and outputs the information of the sensor communication unit 42 and the valve communication unit 43. The sensor communication unit 42 and the valve communication unit 43 include a display unit 44, a memory unit 45 that stores information of the sensor communication unit 42 and the valve communication unit 43, and a remote control device 50 to be described later. It includes a communication unit 46 that receives the user's control information while transmitting information.

At this time, the PCL control unit 41 may be configured to include an operation panel and a switch so that the user can control the operation of the first to ninth control valves (V1 to V9) in the field.

Raw water is supplied to the raw water filtering device 30 or to the water storage tank based on the water quality information measured by the first, second, and third water quality measurement sensors (S1, S2, and S3) by the field control device (40) configured as above. Raw water is controlled to be supplied to (10), and tap water stored in the water storage tank (10) is controlled to be supplied to the user.

The remote control device 50 receives information from the field control device 40 through wired or wireless communication and selectively remotely controls the operation of the field control device 40. This remote control device 50 It may be located in a location relatively far from the water tank 10, such as a management office in a building, and may be composed of a computer with a dedicated program installed so that the user can easily monitor and control it.

The cloud server 60 receives and stores the information of the field control device 40 transmitted from the remote control device 50 through the Internet network and, if necessary, transmits the information to the portable terminal 70 owned by the manager, etc. It is a composition that does.

At this time, the cloud server 60 may be configured to transmit filter replacement information of the raw water filtering device 30, contamination information of raw water, etc. to the portable terminal 70.

Hereinafter, with reference to FIGS. 3 to 7, an example in which the water quality of raw water is measured and filtered through a smart filtering system for preventing tap water contamination in apartment complexes according to the present invention will be described.

(1) When the quality of raw water is normal

If the water quality (turbidity, electrical conductivity) of the raw water measured through the first water quality measurement sensor (S1) is within the normal range, the first control valve (V1) is opened as shown in FIG. 3 and the raw water supply line (L1) is opened. ) is controlled so that raw water is stored in the water storage tank (10).

At this time, the fourth control valve (V4) to the ninth control valve (V9) are maintained in a closed state, and the second and third control valves (V2, V3) are selectively opened and closed to supply tap water to the user.

(2) When raw water is contaminated by particulate contaminants

If the water quality measured through the first water quality measurement sensor (S1) has normal electrical conductivity and turbidity is higher than the standard value, it is determined that the particulate contaminants in the raw water are above the standard value, and in this case, as shown in FIG. 1 Close the control valve (V1) and open the 4th, 6th, and 8th control valves (V4, V6, and V8) to allow raw water to pass through the first and second particulate matter filters (32, 33) of the raw water filtering device (30). It is controlled to pass through and be supplied to the water storage tank (10).

At this time, the water quality of the purified tap water passing through the water return line (L9) is measured through the second water quality measurement sensor (S2). Only when the turbidity is lower than the standard value as a result of the measurement, the eighth control valve (V8) is opened and the water tank (10) is opened. ) is supplied with purified tap water.

On the other hand, if the turbidity of the purified tap water measured through the second water quality measurement sensor (S2) is still higher than the reference value, the eighth control valve (V8) is closed as shown in FIG. 5, and the ninth control valve (V9) is closed instead. ) is opened and the purified tap water flows along the contaminated water inlet line (L4), the particulate matter filter line (L6), and the connection line (L8) and passes through the first and second particulate matter filters (32, 33) again. It is controlled to be purified, and then the water quality of the purified tap water is remeasured through the second water quality measurement sensor (S2) and the above process is repeated.

(2) When raw water is contaminated with ionic contaminants

If the water quality measured through the first water quality measurement sensor (S1) has an electrical conductivity higher than the normal value, it is determined that the ionic contaminants and particulate contaminants in the raw water are above the standard value regardless of turbidity, and in this case, Figure 6 As shown, the first control valve (V1) is closed, and the fourth, fifth, seventh, and eighth control valves (V4, V5, V7, and V8) are opened instead, so that the contaminated raw water flows into the contaminated water inlet line (L4), It flows sequentially through the ionic material filter line (L5), connection line (L7), particulate material filter line (L6), connection line (L8), and water return line (L9) to the ion transport material filter (31), primary The contaminants are controlled to be filtered by sequentially passing through the particulate matter filter 32 and the secondary particulate matter filter 33.

And the water quality of the purified tap water passing through the water return line (L9) is measured through the second water quality measurement sensor (S2). Only when the electrical conductivity is lower than the normal value as a result of the measurement, the eighth control valve (V8) is opened and the water reservoir is opened. Purified tap water is supplied to (10).

On the other hand, if the electrical conductivity of the purified tap water measured through the second water quality measurement sensor (S2) is still higher than the normal value, the eighth control valve (V8) is closed as shown in FIG. 7, and the ninth control valve is opened instead. By opening (V9), the purified tap water flows along the contaminated water inflow line (L4), ionic material filter line (L5), connection line (L7), particulate material filter line (L6), and connection line (L8). It is controlled to be purified by passing through the ionic material filter (31) and the first and second particulate material filters (32, 33) again, and then the water quality of the purified tap water is remeasured through the second water quality measurement sensor (S2). The above process is repeated.

If the electrical conductivity is higher than normal as shown, this is due to the fact that the electrical conductivity cannot be increased without particulate contaminants when purifying tap water through a particulate matter filter regardless of turbidity.

As described above, the present invention measures in advance whether the raw water supplied to the water tank of an apartment or apartment building is contaminated, removes contaminants in the raw water when necessary, and then supplies it to the water tank, so that the tap water stored in the water tank due to contamination of the raw water This can prevent contamination.

In addition, the raw water filtering device is divided into filters that filter out ionic contaminants and particulate contaminants, and the flow path is switched to supply raw water selectively according to the turbidity and electrical conductivity measured through the first water quality measurement sensor, so it is not necessary. In addition, since the particulate matter filter is installed separately into primary and secondary particulate filters depending on the particle size, the service life of the fine particulate matter filter, which has a relatively high replacement cost, can be reduced. can be increased.
