Description

Technical Field

[0001] This utility model relates to the field of heating, and more particularly to a salt dissolving device for a soft water regeneration system. Background Technology

[0002] Water treatment is crucial for the safe and economical operation of boiler equipment. Untreated or improperly treated boiler feedwater will inevitably lead to scale buildup on heating surfaces, reducing the heat transfer performance of the boiler walls, increasing fuel consumption, and causing corrosion, tube rupture, and even explosions, especially in areas with high raw water hardness. Promoting boiler water treatment is of great significance for ensuring the economical and safe operation of boilers, improving boiler efficiency, extending boiler lifespan, and saving energy. Previously, the heating industry commonly used sodium ion exchange resin method because it has advantages over other methods, such as simple system, small equipment, small footprint, and significant softening effect. However, the equipment used in sodium ion exchange resin method has poor filtration efficiency, resulting in poor brine quality and reduced regeneration efficiency. Utility Model Content

[0021] like Figure 1 As shown, the salt dissolving device for a soft water regeneration system includes a dilute salt solution tank 1, a salt dissolving tank 2, a salt distribution plate 5, a filter cap 4, and a filter screen 3. Both the dilute salt solution tank 1 and the salt dissolving tank 2 are hollow shell structures. The dilute salt solution tank 1 is positioned above the salt dissolving tank 2, and the two tanks are connected by a pipeline, allowing circulation between the solutions in the dilute salt solution tank 1 and the salt dissolving tank 2. The top of the salt dissolving tank 2 has an inlet for connecting to an external salt solution pipeline, and the tank is also connected to an external water softener. The salt distribution plate 5 is a rectangular plate structure, positioned inside the salt dissolving tank 2, and salt is placed on the plate. The filter cap 4 is a block structure with filter holes, positioned on top of the salt distribution plate 5. The filter screen 3 is detachably positioned above the filter cap 4, and a predetermined distance is maintained between the filter screen 3 and the filter cap 4. The number of filter caps 4 is multiple, and the multiple filter caps 4 are evenly arranged on the salt distribution plate 5.

[0022] Specifically, the structure of the salt dissolving device used in the soft water regeneration system includes a dilute salt solution tank 1, a salt dissolving tank 2, a salt distribution plate 5, a filter cap 4, and a filter screen 3. To accommodate water and salt, both the dilute salt solution tank 1 and the salt dissolving tank 2 are hollow shell structures. The dilute salt solution tank 1 is positioned above the salt dissolving tank 2. To provide water, a water inlet is provided at the top of the salt dissolving tank 2 and connected to an external water source. Pipelines connect the dilute salt solution tank 1 and the salt dissolving tank 2. To enable circulation between the solution in the dilute salt solution tank 1 and the solution in the salt dissolving tank 2, a salt circulation valve 13 is installed on the pipeline between them. A salt distribution plate 5 is installed inside the salt dissolving tank 2 to hold the salt. Since the salt itself contains a significant amount of impurities, a filter cap 4 is installed for filtration. However, the filter cap 4 is actually a relatively small component, and there are quite a few of them, which makes cleaning them troublesome later. Each filter cap 4 needs to be disassembled and cleaned individually, and they may even be lost. This is because of the filter screen 3, which is located on top of the filter cap 4 and has a preset distance between it and the top of the filter cap 4. The filter screen 3 filters the circulating brine, reduces the filtration pressure on the filter cap 4, and thus reduces the need for cleaning the filter cap 4. The filter screen 3 has a simple structure and is larger than the filter cap 4, making it easier to disassemble and clean.

[0023] In one possible implementation, the area of ​​the filter screen 3 is the same as the area of ​​the bottom of the salt dissolving tank 2, and the diameter of the filter holes on the filter screen 3 is smaller than the diameter of the filter holes on the water filter cap 4.

[0024] Specifically, in order to enable the filter screen 3 to perform secondary filtration and to filter the brine solution comprehensively, the area of ​​the filter screen 3 is set to be the same as the area of ​​the bottom of the salt dissolving tank 2, and the diameter of the filter holes on the filter screen 3 is smaller than the diameter of the filter holes on the water filter cap 4.

[0025] In one possible implementation, a support 6 is further included. The support 6 is a rod-shaped structure with a preset length. The support 6 is disposed inside the salt dissolving tank 2, and two supports 6 are provided. The support 6 passes through the salt distribution plate 5 and the filter screen 3, and the salt distribution plate 5 is located in the upper part of the salt dissolving tank 2.

[0026] Specifically, to better ensure that the salt distribution plate 5 and filter screen 3 can withstand the heavy salt solution while remaining fixed inside the salt dissolving tank 2, a support 6 is provided. The support 5 has a preset length and extends through the salt distribution plate 5 and filter screen 3. The salt distribution plate 5 and filter screen 3 are fixed inside the salt dissolving tank 2 by the support 6, and the connection between the salt distribution plate 5, filter screen 3, and support 6 is detachable. Two supports 6 are provided for better fixation of the salt distribution plate 5 and filter screen 3. Furthermore, to ensure sufficient space for the salt solution formed after dissolving the salt, the salt distribution plate 5 and filter screen 3 are fixed in a relatively high position inside the salt dissolving tank 2. Specifically, as shown... Figure 1 As shown, the salt distribution plate 5 and the filter screen 3 are located at the upper two-thirds position inside the salt dissolving tank 2.

[0027] In one possible implementation, a water level gauge 7 is also included, and two water level gauges 7 are provided, with the two water level gauges 7 respectively located on one side of the dilute brine tank 1 and on one side of the salt dissolving tank 2.

[0028] Specifically, such as Figure 1 As shown, in order to know the position of the salt solution in the dilute salt solution tank 1 and the salt solution in the salt solution tank 2, a water level gauge 7 is installed so that the amount of salt solution in the dilute salt solution tank 1 and the salt solution tank 2 can be observed at any time.

[0029] In one possible implementation, the salt distribution plate 5 has multiple through holes, the positions of which correspond to the positions of the filter cap 4. This makes the overall solution more complete.

[0030] In one possible implementation, the system further includes a brine circulation valve 13, an overflow pipe 9, a dilute brine tank drain valve 12, a dilute brine tank outlet valve 11, a dilute brine tank inlet valve 10, and a magnetically driven pump 8; the top of the salt dissolving tank 2 is connected to the bottom of the dilute brine tank 1 via a first pipeline, and the brine circulation valve 13 is disposed on the first pipeline; the overflow pipe 9 passes through the bottom of the dilute brine tank 1 and the top of the salt dissolving tank 2; the bottom of the dilute brine tank 1 is connected to a second pipeline, the other end of which is connected to the overflow pipe 9, and the dilute brine tank drain valve 12 is disposed on the second pipeline; the other end of the salt dissolving tank 2 is connected to the overflow pipe 9, and the other end of the overflow pipe 9 is connected to the overflow pipe 9, and the dilute brine tank drain valve 12 is disposed on the second pipeline; the other end of the overflow pipe 9 is connected to the bottom of the salt dissolving tank 2. A third pipeline is connected to one side, and an external water softener is connected to the other end of the third pipeline; a fourth pipeline and a fifth pipeline are connected to the other side of the third pipeline and the dilute brine tank 1; the dilute brine tank outlet valve 11 is located on the fourth pipeline and close to the dilute brine tank 1; the dilute brine tank inlet valve 10 is located on the fifth pipeline and close to the dilute brine tank 1, and the dilute brine tank outlet valve 11 is located below the dilute brine tank inlet valve 10; the magnetically driven pump 8 is located on the third pipeline and between the connection point of the third pipeline and the fourth pipeline and the connection point of the third pipeline and the fifth pipeline. It also includes a brine tank outlet valve 15, a rotor flow meter 16, and a water softener brine inlet valve 17. The brine tank outlet valve 15, the rotor flow meter 16, and the water softener brine inlet valve 17 are all located on the third pipeline. The brine tank outlet valve 15 is located between the connection point of the third pipeline and the fourth pipeline and the brine tank 2. The rotor flow meter 16 is located between the connection point of the third pipeline and the fifth pipeline and the external water softener. The water softener brine inlet valve 17 is located between the rotor flow meter 16 and the external water softener. It also includes a brine tank drain valve 18, and a sixth pipeline is connected to the bottom of the brine tank 2. The brine tank drain valve 18 is located on the sixth pipeline.

[0031] Specifically, such as Figure 1 As shown, the brine circulation valve 13, overflow pipe 9, dilute brine tank drain valve 12, dilute brine tank outlet valve 11, dilute brine tank inlet valve 10, magnetic drive pump 8, salt dissolving tank outlet valve 15, rotor flow meter 16, water softener brine inlet valve 17, and salt dissolving tank drain valve 18 are all provided to make the overall structure more complete.

[0032] The sizes of the dilute brine tank 1 and the salt dissolving tank 2 are determined according to actual needs, and the required amount of salt is also adjusted according to actual needs, so that the final brine concentration can be controlled at 8%-10%. Furthermore, the inlet valve 10, outlet valve 11, drain valve 12, brine circulation valve 13, brine mixing valve 14, outlet valve 15, brine inlet valve 17, and drain valve 18 of the brine dissolving tank are all made of ABS material.

[0033] When using this application: Evenly distribute the prescribed amount of coarse-grained salt onto the filter screen 3 above the salt distribution plate 5 inside the salt dissolving tank 2. Open the salt dispensing valve 14 until the liquid level in the salt dissolving tank 2 reaches two-thirds full. Then, open the salt dissolving tank outlet valve 15, the dilute salt solution inlet valve 10, and the salt solution circulation valve 13. Start the magnetic drive pump 8. Observe the water level gauge 7. After both the upper and lower salt tanks are full, close the salt dispensing valve 14. The salt solution circulates in the upper and lower salt tanks until completely dissolved. Stop the pump, close all valves, and allow the solution to settle and clarify in the dilute salt solution tank 1 and the salt dissolving tank 2 for later use. The salt solution concentration can be controlled at 8%-10%. Open the dilute salt solution outlet valve 11, start the external salt pump, and open the water softener inlet valve 17. Pour the salt solution into the water softener according to the water softener regeneration operation procedure. Observe the rotor flow meter 16; the flow rate should be controlled at 2 m / h. Continue until all the salt solution is poured in. Stop the pump, close all valves, and soak the resin for 2-3 hours.

[0034] This application, through the above-described setup, effectively filters out particulate impurities from large salt particles. The salt solution undergoes two-stage precipitation and clarification in the dissolving tank 2 and the dilute salt solution tank 1, resulting in a clear and transparent salt solution, thus greatly improving the regeneration effect. Simultaneously, the dissolving process utilizes a magnetically driven pump 8 for forced circulation, ensuring rapid and efficient dissolving. Furthermore, all piping and valves in this device are made of ABS material, which is corrosion-resistant and has a long service life, solving the technical problem of poor filtration in sodium ion exchange methods, leading to poor salt solution quality and reduced regeneration efficiency.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
