Abstract
Description
Technical Field
[0001] This application relates to the field of water softener equipment technology, and in particular to a water softening system, a water softening system control method, a device, and water softener equipment. Background Technology
[0002] Water contains hardness ions such as calcium and magnesium. These hardness ions negatively impact daily use, including reduced washing performance, decreased thermal efficiency due to scaling on pipe walls, and skin irritation. Water softeners use ion exchange resins to replace these hardness ions, effectively removing them and softening the water. However, the replacement capacity of ion exchange resins is limited; once the resin becomes ineffective, it needs to be regenerated using high-concentration saline solution.
[0003] Conventional water softeners control the salt concentration of the regenerated brine through a siphon method. However, the siphon method (which dilutes saturated brine to a specific concentration) is greatly affected by water pressure fluctuations. Therefore, the regeneration parameters of the entire machine are not fixed during operation, and the softening performance of the entire machine will change accordingly. Summary of the Invention

[0061] In one embodiment, such as Figure 1 As shown, a soft water system is provided, including: a controller, a resin container 120, a constant pressure siphon regeneration device 130, and a water circuit control valve.
[0062] The inlet and outlet of the resin container 120, as well as the inlet of the constant pressure siphon regeneration device 130, are all connected to the inlet of the soft water system. The outlet of the constant pressure siphon regeneration device 130 is connected to the outlet of the resin container 120. The outlet of the resin container 120 is connected to the product water outlet of the soft water system, and the inlet of the resin container 120 is connected to the wastewater outlet of the soft water system. Water circuit control valves are installed at each water circuit connection point of the soft water system, and controllers are connected to the constant pressure siphon regeneration device 130 and the water circuit control valves, respectively.
[0063] The controller is used to start the constant pressure siphon regeneration device 130 in regeneration mode, control the working state of the water circuit control valve, so as to generate brine with a target concentration through the constant pressure siphon regeneration device 130, and drive the brine to flow in reverse in the resin container 120 and then discharge it through the sewage outlet.
[0064] Specifically, the operating states of the water circuit control valve include open and closed states. The operating state of the water circuit control valve is used to determine the specific direction of the water circuit in the soft water system. It should be noted that the specific control method of the water circuit control valve on the direction of the water circuit can be determined according to the type of water circuit control valve and its installation position in the water circuit in the actual application scenario, and is not limited here.
[0065] In a specific embodiment, the constant pressure siphon regeneration device 130 is a regeneration brine generating device with a water pump 137 added as a siphon device 133 to provide the inlet driving force. In this specific embodiment, the constant pressure siphon regeneration device 130 can be used to generate brine with a target concentration and provide a certain water pressure to the brine, causing the brine to flow to the resin container 120.
[0066] In practical applications, this embodiment effectively overcomes the problem of unstable water pressure in the siphon device by adding a constant pressure siphon regeneration device 130 to the soft water system, thereby providing a fixed concentration of regeneration salt solution to the resin container 120 of the soft water system, which greatly improves the regeneration stability and regeneration efficiency of the ion exchange resin in the resin container 120.
[0067] In one embodiment, such as Figure 1 As shown, the soft water system also includes: a pre-filter 110, and water control valves including an inlet valve 140, a product water valve 150, a wastewater valve 160, and a backwash valve 170.
[0068] The inlet of the pre-filter 110 is used to connect to the raw water. The outlet of the pre-filter 110 is connected to the inlet of the resin container 120 through the inlet valve 140. The outlet of the pre-filter 110 is also connected to the outlet of the resin container 120 through the backwash valve 170. The outlet of the pre-filter 110 is also connected to the outlet of the resin container 120 through the constant pressure siphon regeneration device 130. The outlet of the resin container 120 is also connected to the outlet of the soft water system through the product water valve 150. The inlet of the resin container 120 is connected to the outlet of the soft water system through the wastewater valve 160.
[0069] Specifically, in this embodiment, the pre-filter 110 is used to filter large particles in the raw water, such as silt and hair, to preliminarily intercept the water entering the soft water system and ensure the softening efficiency of the soft water system.
[0070] In this embodiment, the resin container 120 is used to load ion exchange resin, and includes an inlet, an outlet, and intercepting nets disposed at the inlet and outlet of the resin container 120. It should be noted that the resin container 120 in this embodiment is placed horizontally, meaning that inside the tank, the water flow direction is parallel to the ground and flows horizontally. Compared to the conventional placement of water softeners where the water flow direction is perpendicular to the ground, the resin container 120 in this embodiment is flatter and does not occupy height space, thereby effectively reducing the size of the water softener equipment.
[0071] In addition, the resin container 120 in this embodiment may include only one layer of resin flow channel, making the tank flow channel a single straight-line flow channel. Alternatively, the resin container 120 in this embodiment may include multiple layers of resin flow channels, with partitions separating the channels. The resin container 120 may also achieve channel separation by bending and splicing the tank body. In a preferred embodiment, the resin container 120 with a multi-layer resin flow channel structure effectively increases the effective contact distance between water and resin, thereby improving the softening performance of the water softening system.
[0072] In this embodiment, the inlet valve 140, product water valve 150, wastewater valve 160, and backwash valve 170 can all be solenoid valves. It should be noted that this embodiment does not limit the specific form of the valves; they can be configured according to the needs of the actual application scenario. For example, the inlet valve 140 and backwash valve 170 can also be a single-position two-way solenoid valve, including one inlet and two outlets, with the two outlets respectively connected to the inlet and outlet of the resin container 120.
[0073] The controller is connected to the constant pressure siphon regeneration device 130, the inlet valve 140, the product water valve 150, the sewage valve 160, and the backwash valve 170, respectively.
[0074] The controller is used to start the constant pressure siphon regeneration device 130 in regeneration mode, and to close the inlet valve 140, the product water valve 150, the backwash valve 170, and the wastewater valve 160, so as to generate brine with a target concentration through the constant pressure siphon regeneration device 130, and drive the brine to flow in reverse in the resin container 120 and then discharge it through the wastewater valve 160.
[0075] In a specific embodiment, the water softening system mainly includes a water production mode and a regeneration mode. In the water production mode, the water softening system is used to soften raw water through the resin container 120 to obtain soft water after removing hardness ions. In the regeneration mode, the water softening system is used to regenerate the ion exchange resin in the resin container 120 using a brine solution of a certain concentration.
[0076] This embodiment adds a constant-pressure siphon regeneration device 130 to the soft water system and a water pump 137 to the inlet of the siphon device 133 to provide water inlet power. This allows water to flow into the siphon device 133 with a certain driving force, enabling the siphon device 133 to stably generate a siphon effect. A certain amount of high-concentration salt solution is drawn from the salt tank 132 to generate brine with the target concentration. This effectively improves the abnormal phenomenon in the prior art where the siphon device is affected by water pressure fluctuations, resulting in unstable brine concentration. Furthermore, the soft water system provided in this embodiment has a simpler structure, efficiently generating brine while effectively improving the utilization efficiency of regenerated salt and the regeneration efficiency of ion exchange resin.
[0077] In one embodiment, such as Figure 2As shown, the constant pressure siphon regeneration device 130 includes a water tank 131, a brine tank 132, a siphon device 133, a first water supply valve 134, a second water supply valve 135, a brine valve 136, and a water pump 137. The outlet of the pre-filter 110 is connected to the water tank 131 via the first water supply valve 134, and the outlet of the pre-filter 110 is connected to the brine tank 132 via the second water supply valve 135. The outlet of the water tank 131 is connected to the first opening of the siphon device 133 via the water pump 137. The second opening of the siphon device 133 is connected to the outlet of the resin container 120, and the third opening of the siphon device 133 is connected to the brine inlet 1322 of the brine tank via the brine valve 136.
[0078] Specifically, the salt tank 132 includes a porous support plate 1321 and a salt intake port 1322. The porous support plate 1321 is positioned at a predetermined distance from the bottom of the salt tank 132, and the porous support plate 1321 and the side of the salt tank 132 form a regenerated salt storage area for storing regenerated salt. Specifically, as... Figure 2 As shown, the regenerated salt storage area is the area above the porous support plate 1321. It should be noted that in this embodiment, the porous support plate 1321 is arranged laterally and sealed to the side of the salt tank 132 to ensure the stability of the porous support plate 1321. It should be noted that the sealing connection in this embodiment can employ methods such as glue sealing, welding sealing, or sealing ring sealing, or it can be integrally formed with the container. This embodiment does not limit the specific arrangement of the porous support plate 1321.
[0079] The porous support plate 1321 and the bottom of the salt tank 132 form a saturated brine region, which is used to store the target brine. Specifically, as shown... Figure 2 As shown, the saturated salt solution region is the area below the porous support plate 1321.
[0080] The brine inlet 1322 is located at the bottom of the saturated brine area, and the brine inlet 1322 is connected to the third opening of the siphon device 133 through the brine valve 136.
[0081] Specifically, in this embodiment, the orifice diameter of the third opening of the siphon device 133 is larger than that of the second opening, and the orifice diameter of the first opening is larger than that of the third opening. The orifice diameter relationship of the openings in the siphon device 133 is designed to achieve the siphon effect. Water enters the siphon device 133 through the first opening under the driving force provided by the water pump 137. The third opening absorbs high-concentration brine from the brine inlet 1322 through the siphon effect, and finally outputs brine with the target concentration through the second opening.
[0082] Specifically, the actual size parameters of the opening diameters of the first opening, the second opening, and the third opening can be determined according to the required water flow rate in the actual application scenario. This embodiment does not limit the size parameters of the opening diameters.
[0083] In actual control, when the controller starts the water pump 137 and opens the brine valve 136, the water in the water tank 131 flows to the first opening according to the preset flow parameters, and the target brine in the brine tank 132 flows to the third opening through the brine suction port 1322. The second opening of the siphon device 133 outputs brine with the target concentration.
[0084] When the controller starts the water pump 137 and closes the brine valve 136, the water in the water tank 131 flows to the first opening according to the preset flow parameters, and the second opening of the siphon device 133 outputs water.
[0085] This embodiment provides a constant pressure siphon regeneration device 130 that can stably generate brine with a target concentration, effectively overcoming water pressure fluctuations in the siphon device. By generating a siphon effect through stable water pressure, it effectively improves the stability and accuracy of brine generation in the soft water system.
[0086] In one embodiment, the regeneration mode includes a backwashing phase, a salt absorption regeneration phase, and a slow wash phase.
[0087] During the backwashing phase, the controller controls the constant pressure siphon regeneration device 130 to close, the inlet valve 140 to close, the product water valve 150 to close, the backwash valve 170 to open, and the sewage valve 160 to open, so that the water filtered by the pre-filter 110 flows in reverse in the resin container 120, and the sewage generated by the backwash resin container 120 is output through the sewage valve 160.
[0088] Specifically, this embodiment controls the soft water system to complete the backwashing stage before the salt absorption and regeneration stage, which can provide a more favorable environment for the ion exchange resin to contact the salt solution during the salt absorption and regeneration stage, allowing the ion exchange resin to fully contact the salt solution.
[0089] During the salt absorption and regeneration stage, the controller starts the constant pressure siphon regeneration device 130, closes the inlet valve 140, closes the product water valve 150, closes the backwash valve 170, and opens the sewage valve 160. This allows the constant pressure siphon regeneration device 130 to generate brine with the target concentration, and drives the brine to flow in reverse in the resin container 120 before being discharged through the sewage valve 160.
[0090] Specifically, during the salt absorption and regeneration stage, the soft water system generates brine with a preset concentration and controls the brine to enter from the outlet of the resin container 120 and flow out from the inlet of the resin container 120. The brine flows through the pipes and surface of the ion exchange resin inside the resin container 120, so that the regenerated salt comes into contact with the ion exchange resin, thereby regenerating the ion exchange resin.
[0091] During the slow wash phase, the controller starts the constant pressure siphon regeneration device 130, closes the inlet valve 140, closes the product water valve 150, closes the backwash valve 170, and opens the sewage valve 160, so that water is output through the constant pressure siphon regeneration device 130 and drives the water to flow in reverse in the resin container 120 before being discharged through the sewage valve 160.
[0092] Specifically, during the slow wash phase, the soft water system controls the water to bypass the brine tank 132 and enter again from the outlet of the resin container 120 and flow out from the inlet of the resin container 120. This utilizes the residual regenerated salt in the dissolved salt regeneration station of the soft water system to fully regenerate the ion exchange resin in the resin container 120 and make full use of the regenerated salt in the water pipes to reduce waste of regenerated salt.
[0093] In one embodiment, in water production mode, the controller controls the constant pressure siphon regeneration device 130 to close, and controls the inlet valve 140 to open, the water production valve 150 to open, the backwash valve 170 to close, and the sewage valve 160 to close, so that the water filtered by the pre-filter 110 flows forward in the resin container 120, and the water softened by the resin container 120 is output through the water production valve 150.
[0094] Specifically, in the water production mode, the raw water first undergoes preliminary purification through the pre-filter 110 to obtain filtered water. At this time, the controller controls the inlet valve 140 and the water production valve 150 to open, while other switches are closed. This allows the pre-purified filtered water to flow into the resin container 120 from the inlet and flow along the resin channels arranged laterally in the resin container 120. The ion exchange resin fully softens the water, and the softened water is discharged from the outlet of the resin container 120 and flows out through the water production valve 150 to the outlet of the softened water system, thus outputting the water softened by the resin container 120.
[0095] This embodiment employs a resin container 120 with horizontally arranged resin channels, which effectively extends the contact area between the ion exchange resin and water in the resin container 120, thereby greatly improving the water softening capacity of the water softening system and providing higher quality soft water.
[0096] In one embodiment, the water tank 131 includes a first liquid level switch 1311, which is located at a preset distance from the top of the water tank 131. The controller is connected to the first liquid level switch 1311 to obtain the first liquid level in the water tank 131.
[0097] When the first liquid level is less than the first liquid level threshold, the controller controls the first water supply valve 134 to open until the first liquid level is greater than or equal to the first liquid level threshold.
[0098] Specifically, in this embodiment, water can be added to the water tank 131 at any stage. When the first liquid level switch 1311 sends a liquid level signal to the controller, it indicates that the first liquid level in the water tank 131 is greater than or equal to the first liquid level threshold. At this time, the first water replenishment valve 134 can be closed to stop the water replenishment to the water tank 131.
[0099] In one embodiment, the salt tank 132 includes a second liquid level switch 1323, which is disposed near the porous support plate 1321 and spaced at a preset distance from the porous support plate 1321. The controller is connected to the second liquid level switch 1323 to obtain the second liquid level in the salt tank 132.
[0100] When the second liquid level is lower than the second liquid level threshold, the controller controls the second water supply valve 135 to open until the second liquid level is greater than or equal to the second liquid level threshold.
[0101] Specifically, in this embodiment, the salt tank 132 can be replenished with water at any stage. Preferably, the control can be performed after the slow wash stage is completed, and then the second water replenishment valve 135 can be opened to replenish the salt tank 132 with water.
[0102] When the second liquid level switch 1323 sends a liquid level signal to the controller, it indicates that the second liquid level in the brine tank 132 is greater than or equal to the second liquid level threshold. At this time, the second water supply valve 135 can be closed to stop the continued replenishment of water to the brine tank 132.
[0103] In one embodiment, the resin container 120 includes a predetermined number of resin channels, and the water flow direction within the resin channels is horizontal.
[0104] In a specific embodiment, the resin container 120 is placed horizontally. The resin container 120 can have a structure including only one layer of resin channels or a structure including multiple layers of resin channels. It should be noted that the length of a single layer of resin channels in the resin container 120 with a multi-layer resin channel structure is shorter than the length of a single layer of resin channels in the resin container 120 with a single-layer resin channel structure.
[0105] This embodiment can divide the resin container 120 flow channels by setting a partition plate, thereby achieving a longer resin flow channel within a fixed tank size, which can further improve the exchange rate between the resin and hardness ions in the water, and effectively improve the softening ability of the needle water softening system.
[0106] In one embodiment, the water softening system further includes a water supply valve 180, wherein the outlet of the pre-filter 110 is connected to the water production outlet of the water softening system via the water supply valve 180.
[0107] In water production mode, the controller closes the water supply valve 180; in regeneration mode, the controller opens the water supply valve 180.
[0108] In a specific embodiment, the controller can also keep the water supply valve 180 open in regeneration mode to ensure that the water softening system can continuously supply water to the outlet, avoiding affecting the normal water supply process of the water softener. It should be noted that the water supplied by the water softening system at this time is water that has undergone preliminary purification by the pre-filter 110.
[0109] In summary, this embodiment provides a water softening system. By providing a constant-pressure siphon regeneration device, it effectively solves the problem of water pressure fluctuation affecting the generation of target brine by the siphon device. It can stably generate brine with the target concentration. Furthermore, by using a horizontally arranged resin container, it effectively increases the contact area between the ion exchange resin and the brine, greatly improving the resin regeneration capacity of the water softening system and effectively improving the utilization rate of regenerated salt, avoiding waste of regenerated salt, and preventing the environmental damage caused by high-concentration brine.
[0110] In one embodiment, a soft water system control method is also provided, which is applied to Figure 1 Taking a soft water system as an example, the following steps are included:
[0111] S501, In regeneration mode, the constant pressure siphon regeneration device is started, and the working state of the water circuit control valve is controlled so as to generate brine with the target concentration through the constant pressure siphon regeneration device;

[0113] Specifically, the specific implementation method of the soft water system control method in this embodiment can be referred to the specific implementation method in the aforementioned system embodiment, which will not be repeated here.
