Description

Technical Field

[0001] The present application relates to the technical field of water softener equipment, and in particular to a regeneration salt solution generating device, a resin softening system and equipment. Background Art

[0002] Water contains hardness ions such as calcium and magnesium. The impact of hardness ions on daily use includes poor washing effect, reduced thermal efficiency after scaling of pipe walls, and skin irritation. Water softeners can use ion exchange resins to replace hardness ions in water, thereby effectively removing hardness ions in water and softening water. The replacement capacity of ion exchange resins is limited. When the resin fails, it needs to be regenerated with the help of high-concentration salt water.

[0003] In the regeneration mode of conventional water softener equipment, the steps for obtaining regeneration salt solution of a specific concentration include a salt dissolving step and a siphon step, wherein the salt dissolving step requires first adding water to the salt box loaded with solid salt particles to dissolve the salt, and the high-concentration salt solution generation process requires a certain amount of salt dissolving time. Therefore, there is a certain time interval between the generation and use of the high-concentration salt solution, which is not timely. At the same time, it is necessary to set up enough storage space in the salt box for the generated salt solution. The increase in the salt solution storage space will simultaneously increase the volume of the salt box, which is not conducive to the miniaturization design of the water softener equipment. The high-concentration salt solution in the storage space is sucked by the siphon device in the siphon step, and the regeneration salt solution is formed in combination with the water flowing in the siphon device. Due to the pressure instability of the siphon device, the regeneration salt solution of a fixed concentration cannot be stably generated. Utility Model Content

[0014] In one embodiment, if the regeneration salt chamber includes at least two dissolved salt flow channels, the flow channel communication opening at the connection between two adjacent dissolved salt flow channels is greater than or equal to the particle diameter of the regeneration salt.

[0015] In one embodiment, the regeneration salt chamber includes a liquid inlet disposed on a side of the dissolved salt flow channel;

[0016] If the regeneration salt chamber includes at least two layers of dissolved salt flow channels, the liquid inlet is arranged on the side of the uppermost layer of dissolved salt flow channels.

[0017] In one embodiment, the pore size of the porous partition is smaller than the maximum particle diameter of the regeneration salt.

[0018] In one of the embodiments, the saline liquid chamber includes a liquid outlet disposed on a side of the saline liquid chamber;

[0019] The position of the liquid outlet on the side of the salt liquid cavity is lower than the lowest plane of the dissolved salt flow channel.

[0020] In one embodiment, the height of the molten salt flow channel is greater than or equal to 3 times the particle diameter of the regeneration salt, and the width of the molten salt flow channel is greater than or equal to 2 times the particle diameter of the regeneration salt.

[0021] In one embodiment, the cross-sectional shape of the molten salt flow channel is any one of square, trapezoidal, triangular or semicircular.

[0022] In a second aspect, this embodiment provides a resin softening system, comprising the regeneration salt solution generating device described in the first aspect.

[0023] In a third aspect, this embodiment provides a water softener device, including the resin softening system described in the second aspect.

At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0043] As mentioned in the background technology section above, most of the existing brine tanks in soft water systems use Figure 1 In the structure shown, the salt box is divided into two layers by a porous partition, a large amount of regeneration salt is placed on the upper layer of the porous partition, and a salt liquid collection chamber is formed below the porous partition. By replenishing the water in the salt liquid collection chamber, the water is in contact with the regeneration salt above, and a salt liquid of a certain concentration is formed after contact, and finally the salt liquid is output through the water outlet.

[0044] The main problem of the existing salt tank is that the contact area between the water and the regeneration salt is small. If a high-concentration salt solution needs to be generated, it takes a long time to wait for the regeneration salt to dissolve. Figure 1 The resin softening system of the salt box shown cannot achieve the regeneration efficiency of the ion exchange resin by controlling the inlet and outlet flow rates of the salt box.

[0045] The present embodiment provides a novel regeneration salt solution generating device, which can effectively extend the length of the dissolved salt flow channel, thereby effectively increasing the contact area between the regeneration salt and the water body, and can generate high-concentration salt water more efficiently and stably. The structure of the regeneration salt solution generating device provided in the present embodiment can cooperate with the resin softening system to achieve instant adjustment of the salt water concentration, thereby further improving the utilization rate of the regeneration salt.

[0046] like Figure 2 As shown, a regeneration salt solution generating device is provided, which is applied to a resin softening system and includes: a regeneration salt chamber 110 and a salt solution chamber 120 .

[0047] The regeneration salt chamber 110 is used to store the regeneration salt. Specifically, the regeneration salt chamber 110 includes at least one salt-dissolving flow channel 111. When the liquid passes through the salt-dissolving flow channel 111, the liquid flows in a horizontal direction and dissolves the solid regeneration salt in the flow direction.

[0048] Specifically, the tank structure of the regeneration salt chamber 110 in this embodiment forms at least one molten salt flow channel 111, and the length of the molten salt flow channel 111 should be at least greater than or equal to the preset length threshold. Among them, the preset length threshold should meet the demand of the resin softening system to generate a target salt solution with a minimum concentration. This embodiment does not limit the preset length threshold, and the length of the molten salt flow channel 111 can be configured according to the needs of the actual application scenario.

[0049] In a specific embodiment, in order to ensure that the regeneration salt in the regeneration salt chamber 110 can fully contact with the water body to form a regeneration salt solution with a certain concentration, the total length of the regeneration salt chamber 110 in the transverse direction is greater than the total length in the longitudinal direction.

[0050] Specifically, as shown in the accompanying drawings, the tank body of the regeneration salt solution generating device in this embodiment can be configured as a single-layer tank body or a multi-layer tank body.

[0051] If the tank body of the regeneration salt solution generating device is set as a horizontal single-layer tank body, since the tank body is placed horizontally, the entire machine corresponding to the tank body does not occupy space in height. At the same time, in terms of length, the molten salt flow channel can extend in both directions. Therefore, the regeneration salt solution generating device in this embodiment is also controllable in the lateral space.

[0052] In some specific embodiments, in order to reduce the length of the lateral space occupied by the whole machine, the tank body of the regeneration salt solution generating device can also be set as a connected double-layer or multi-layer tank body to make the whole machine structure more compact. When the tank body is a connected double-layer or multi-layer tank body, different from a single-layer tank body, the water flow direction at the connection of each layer of the soluble salt flow channel is a local vertical flow, but the water flow direction of the main flow channel is still a lateral flow.

[0053] It should be noted that when the regenerated salt chamber 110 includes multiple molten salt flow channels, the total length in the lateral direction is the sum of the lengths of the lateral spaces formed by the multiple molten salt flow channels arranged laterally, and the total length in the longitudinal direction is the sum of the lengths of the longitudinal spaces formed by the bends between the multiple molten salt flow channels.

[0054] The regenerated salt chamber 110 in this embodiment can form a plurality of dissolved salt flow channels 111 by integrated forming. When the regenerated salt solution generating device includes a plurality of dissolved salt flow channels 111, the amount of regenerated salt stored in the regenerated salt chamber 110 will increase, and the contact area between the regenerated salt and the water body will increase with the increase in the total length of the dissolved salt flow channels 111, thereby effectively expanding the contact area between the regenerated salt and the water body, which is more conducive to the generation of high-concentration salt water.

[0055] Specifically, the regeneration salt chamber 110 in this embodiment is used to access the liquid with a preset liquid flow rate and a preset temperature in the regeneration mode, and instantly generate a saline solution with a preset concentration. The saline solution chamber 120 in this embodiment is used to access the saline solution with a preset concentration instantly generated by the regeneration salt chamber 110 in the regeneration mode, and output the saline solution instantly to the resin container in the resin softening system. It should be noted that if the resin softening system is not in the regeneration mode, the regeneration salt chamber 110 is not connected to the liquid, and the saline solution chamber 120 is not connected to the saline solution.

[0056] Specifically, when the regeneration salt solution generating device in the present embodiment is applied to the resin softening system, when the resin softening system needs to generate a salt solution with a target concentration, the water body will be controlled to enter from the liquid inlet 112 of the regeneration salt chamber 110 according to the preset flow parameters and the preset temperature parameters, and move horizontally along the ground plane of the soluble salt flow channel 111, wherein the water body moves with the driving force of the water. The water body immediately combines the regeneration salt stored inside the soluble salt flow channel 111 after entering the regeneration salt chamber 110 to form salt water. During the movement of the water body, the water body will first merge with the regeneration salt particles located at the bottom of the soluble salt flow channel 111. After the bottom regeneration salt is consumed, the regeneration salt particles located above the soluble salt flow channel 111 will fall to the bottom to fill the regeneration salt particles in contact with the water body, thereby being able to stably generate a high-concentration salt solution.

[0057] It should be noted that the salt concentration is not affected by the change in the number of regeneration salt particles above the dissolved salt flow channel 111. When the target salt solution is generated by the regeneration salt solution generating device provided in this embodiment, the salt concentration of the target salt solution is only related to the total amount of regeneration salt stored in the dissolved salt flow channel 111. The driving force of the water body can be provided by a water pump.

[0058] In actual application, the resin softening system equipped with the regeneration salt solution generating device provided in this embodiment only needs to control the preset liquid flow rate and the water body of preset temperature to enter the regeneration salt solution generating device, so as to be able to instantly generate a regeneration salt solution with a certain concentration, and there is no need to consider the stability influence of the siphon pressure, and the concentration of the regeneration salt solution can be flexibly and accurately controlled. And the regeneration salt cavity of the regeneration salt solution generating device provided in this embodiment includes at least one laterally arranged molten salt flow channel, which can effectively increase the contact area between the regeneration salt and the water body, thereby improving the generation efficiency of the high-concentration salt solution and improving the utilization rate of the regeneration salt.

[0059] In one embodiment, the total length of the regeneration salt chamber 110 in the lateral direction increases with the increase of the preset concentration of the salt solution.

[0060] In the specific implementation process, when the resin softening system requires a higher concentration of regeneration salt solution for ion exchange resin regeneration, the total length of the regeneration salt chamber 110 in the lateral direction can be effectively extended by increasing the dissolved salt flow channel 111 in the regeneration salt chamber 110, thereby effectively increasing the contact area between the water body and the regeneration salt, thereby increasing the concentration of the salt solution output by the regeneration salt solution generating device.

[0061] It should be noted that the total length of the regeneration salt chamber 110 in the transverse direction can also be increased by directly extending the length of the salt dissolving channel 111 of the regeneration salt chamber 110. This embodiment does not limit the specific measures taken to extend the total length of the regeneration salt chamber 110 in the transverse direction, and a reasonable extension method can be adopted according to the needs of the actual application scenario.

[0062] In one embodiment, Figure 2 As shown, the regeneration salt solution generating device further includes: a porous partition 130 , wherein the regeneration salt chamber 110 and the salt solution chamber 120 are separated by the porous partition 130 , and the porous partition 130 is longitudinally arranged between the regeneration salt chamber 110 and the salt solution chamber 120 .

[0063] Specifically, the porous partition 130 in the present embodiment is used to divide the regeneration salt solution generating device into a regeneration salt chamber 110 and a salt solution chamber 120, and the porous partition 130 is longitudinally arranged on the inner bottom tank of the regeneration salt solution generating device. It should be noted that the opening aperture of the porous partition 130 is smaller than the maximum diameter of the particles of the regeneration salt. The porous partition 130 can isolate the regeneration salt particles on one side of the regeneration salt chamber 110, isolate the high-concentration salt solution on one side of the salt solution chamber 120, and the porous partition 130 can effectively filter the salt solution flowing out of the regeneration salt chamber 110, while preventing the regeneration salt from entering the salt solution chamber 120 in large quantities from the regeneration salt chamber 110.

[0064] Specifically, in this embodiment, the horizontal arrangement refers to an arrangement parallel to the ground plane. In this embodiment, the vertical arrangement refers to an arrangement perpendicular to the ground plane.

[0065] In one embodiment, Figure 3 As shown, the regeneration salt chamber 110 further includes n-1 flow channel partitions 140 , wherein n is a positive integer greater than or equal to 2.

[0066] The channel separator 140 is arranged on the side wall of the regeneration salt chamber 110 to separate n dissolved salt channels 111 from the regeneration salt chamber 110, and two adjacent separators are arranged on different sides of the regeneration salt chamber 110 so that the liquid in the two adjacent dissolved salt channels 111 moves in different directions.

[0067] Specifically, the regenerated salt chamber 110 in this embodiment can be a complete chamber space, and the division of the soluble salt flow channel 111 is achieved by the flow channel divider 140. In a specific implementation, when the soluble salt flow channel 111 is divided by the flow channel divider 140, the total flow channel length of the soluble salt flow channel 111 in the soluble salt chamber can be more flexibly controlled. For example, for the same regenerated salt chamber 110, when there is space to configure one flow channel divider 140 and two flow channel dividers 140, the user can determine whether to configure one flow channel divider 140 or two flow channel dividers 140 according to the concentration requirements of the brine in the actual application scenario. If the user needs a higher concentration of brine, you can consider configuring more flow channel dividers 140 to divide more soluble salt flow channels 111, thereby effectively increasing the contact area between the regenerated salt and the water body.

[0068] In a specific implementation, two adjacent flow channel partitions 140 need to be respectively disposed on different sides of the regeneration salt chamber 110 to ensure that water can flow through each dissolved salt flow channel 111 .

[0069] In a feasible embodiment, the flow channel partition 140 in this embodiment can be a retractable partition. When it is necessary to extend the total length of the regenerated salt chamber 110 in the lateral direction, the expansion of the flow channel partition 140 can be controlled to increase the molten salt flow channel 111, so as to increase the concentration of the salt solution output by the regenerated salt solution generating device.

[0070] In one embodiment, if the regeneration salt chamber 110 includes at least two dissolved salt flow channels 111 , the flow channel communication opening 113 at the connection between two adjacent dissolved salt flow channels 111 is greater than or equal to the particle diameter of the regeneration salt.

[0071] Specifically, when the regeneration salt chamber 110 includes multiple dissolved salt flow channels 111, the connection between adjacent dissolved salt flow channels 111 includes a flow channel connecting port 113, and the diameter of the flow channel connecting port 113 should be at least greater than or equal to the particle diameter of one regeneration salt to ensure that the water body can stably flow from the upper dissolved salt flow channel 111 through the connecting port 113 to the lower dissolved salt flow channel 111, and will not cause blockage between the dissolved salt flow channels 111 due to the presence of regeneration salt that has not been completely dissolved in the water body.

[0072] In a feasible embodiment, the flow channel connecting port 113 can be realized by using a flow channel partition 140 whose length is less than the effective length of the dissolved salt flow channel 111 , or by directly opening a hole in the inner integral structure of the regenerated salt chamber 110 .

[0073] In one embodiment, the regeneration salt chamber 110 includes a liquid inlet 112 arranged on the side of the dissolved salt flow channel 111. Specifically, in this embodiment, the liquid inlet 112 of the regeneration salt chamber 110 is arranged on the side of the dissolved salt flow channel 111, so that it is more conducive to the water body to flow directly from the side to the bottom plane of the dissolved salt flow channel 111 inside the regeneration salt chamber 110, and preferentially dissolve with the regeneration salt on the bottom plane.

[0074] If the regeneration salt chamber 110 includes at least two layers of dissolved salt flow channels 111 , the liquid inlet 112 is disposed on the side of the uppermost dissolved salt flow channel 111 .

[0075] In a specific embodiment, when the regeneration salt chamber 110 includes multiple layers of dissolved salt flow channels 111, each dissolved salt flow channel 111 is horizontally distributed in a top-to-bottom order. Therefore, the liquid inlet 112 needs to be arranged on the side of the uppermost dissolved salt flow channel 111 to ensure that the water can flow through all dissolved salt flow channels 111.

[0076] In one embodiment, the saline liquid chamber 120 includes a liquid outlet 121 disposed on a side of the saline liquid chamber 120;

[0077] The position of the liquid outlet 121 on the side of the salt liquid chamber 120 is lower than the lowest plane of the dissolved salt flow channel 111 .

[0078] Specifically, Figure 2 and Figure 3 As shown, the positions of the liquid outlets 121 on the side of the salt liquid chamber 120 are all set lower than the lowest plane of the dissolved salt flow channel 111, wherein the lowest plane of the dissolved salt flow channel 111 corresponds to the lowest plane of the regenerated salt chamber 110.

[0079] In actual application, the salt liquid chamber is mainly used to collect the high-concentration salt liquid generated in real time. The lowest plane of the salt liquid chamber 120 will be lower than the lowest plane of the solid salt chamber to ensure that the overflowing salt liquid will be discharged in time through the liquid outlet 121 and will not accumulate in the dissolved salt flow channel 111 to affect the salt concentration of the generated target salt liquid.

[0080] In one embodiment, the height of the molten salt flow channel 111 is greater than or equal to 3 times the particle diameter of the regeneration salt, and the width of the molten salt flow channel 111 is greater than or equal to 2 times the particle diameter of the regeneration salt.

[0081] In this embodiment, the parameters of the molten salt flow channel 111 should at least meet the requirements that the height is greater than or equal to 3 times the diameter of the regeneration salt particles, that is, at least 3 regeneration salt particles can be stored in the height space. The width is greater than or equal to 2 times the diameter of the regeneration salt particles, that is, at least 2 regeneration salt particles can be stored in the width space.

[0082] It should be noted that the total length of the salt dissolving channel 111 in this embodiment can be configured according to the needs of the actual application scenario. In the specific application process, the change of salt concentration with the increase of the channel length is as follows: Figure 4 As shown, the longer the length of the dissolved salt flow channel 111 is, the higher the salt concentration is.

[0083] Things to know: Figure 4 The relationship between the salt concentration and the flow channel length is obtained by testing at a fixed water temperature and in an instant soluble salt regeneration mode. The instant soluble salt regeneration mode is a resin regeneration treatment mode in which the water flows through the regeneration salt solution generating device provided in this embodiment, and then directly outputs salt water with a target concentration to the resin container through the liquid outlet 121 of the regeneration salt solution generating device.

[0084] In one embodiment, the cross-sectional shape of the molten salt flow channel 111 is any one of square, trapezoid, triangle or semicircle.

[0085] In a specific embodiment, the specific structure of the molten salt flow channel 111 in this embodiment can be determined according to the needs of the actual application scenario, and this embodiment does not limit the structure of the molten salt flow channel 111. Preferably, the cross-sectional shape of the molten salt flow channel 111 can be square to facilitate the storage of more regenerated salt.

[0086] In summary, the present embodiment provides a regeneration salt solution generating device, which effectively extends the length of the dissolved salt flow channel, can achieve the adaptability increase of the dissolved salt flow channel length in the regeneration salt solution generating device, cooperates with the salt solution generation demand of the resin softening system, and stably provides high-concentration salt solution for the ion exchange resin in the resin container, thereby greatly improving the resin regeneration capacity of the resin softening system, and improving the utilization efficiency of the regeneration salt, saving resources.

[0087] In addition, if Figure 5 As shown, this embodiment also provides a resin softening system, including the regeneration salt solution generating device in the aforementioned embodiment.

[0088] Specifically, the resin softening system should at least include a first water pump 512, a regeneration salt solution generating device 503 and a second water pump 513, wherein the first water pump 512 is used to provide an inlet flow rate for the regeneration salt solution generating device 503, and the second water pump 513 is used to provide an outlet flow rate for the regeneration salt solution generating device 503. The first water pump 512 pumps water from the water tank to the liquid inlet 112 of the regeneration salt solution generating device 503, generates salt water with a target concentration based on the specific structure of the regeneration salt solution generating device 503 in the aforementioned embodiment, and the second water pump 513 pumps the salt water with the target concentration into the resin container 502 to complete the regeneration of the ion exchange resin in the resin container 502.

[0089] In a feasible embodiment, the resin softening system may further include a heating module 515, wherein the heating module 515 is used to heat the liquid input to the regeneration salt solution generating device 503 to ensure that the temperature of the regeneration salt solution generated by the regeneration salt solution generating device 503 is always at an optimal temperature that is conducive to the regeneration of the ion exchange resin.

[0090] The resin softening system provided in this embodiment adopts a new type of regeneration salt solution generating device, which can provide a more stable regeneration salt water with a certain concentration, and can complete the instant adjustment of the salt water concentration by changing the length of the dissolved salt flow channel in the regeneration salt solution generating device, thereby greatly improving the flexibility of the resin softening system.

[0091] In addition, if Figure 5 As shown, this embodiment also provides a plug-flow softening water system, including the regeneration salt solution generating device in the aforementioned embodiment.

[0092] The soft water system includes a pre-filter 501, a resin container 502, a regeneration salt solution generating device 503, a water tank 504, a controller, a first switch component 505, a second switch component 506, a third switch component 507, a fourth switch component 508, a fifth switch component 509, a sixth switch component 510, a seventh switch component 511, a first water pump 512, a second water pump 513, an eighth switch component 514 and a heating module 515.

[0093] It should be noted that the plug-flow softening water system in this embodiment is only used as an example. The plug-flow softening water system can also add corresponding equipment according to the needs of actual application scenarios. This embodiment does not specifically limit the actual structure of the plug-flow softening water system.

[0094] like Figure 6 As shown, this embodiment also provides a resin softening system control method, including:
