Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment, specifically to a boiler soft water device. Background Technology

[0002] Hard water refers to water containing a high amount of soluble calcium and magnesium compounds. Soft water refers to water with a hardness of less than 8 degrees, containing fewer soluble calcium and magnesium compounds. In modern industrial production, hard water easily causes boiler scaling, and in severe cases, can even lead to boiler explosions. Therefore, in existing boiler feedwater processes, water softening devices are needed to soften the water and reduce the content of calcium and magnesium compounds.

[0003] Existing boiler water softening systems have the following drawbacks:

[0004] 1. Existing boiler water softening devices do not have the function of filtering hard water during use, which can easily lead to internal contamination and blockage, reducing the practicality of the water softening device.

[0005] 2. Existing boiler water softening devices do not have the function of uniform spraying when hard water is injected, which reduces the quality of hard water conversion and reduces the practicality of the water softening device.

[0006] 3. Existing boiler water softening systems are not convenient for replacing resins that have lost their ion exchange capacity after long-term use. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a boiler water softening device with a split structure and a detachable softening component, which facilitates the replacement of ion exchange resin that has been worn out after long-term use.

[0031] The present invention will now be described in detail with reference to the accompanying drawings:

[0032] Example: As attached Figures 1-3 As shown, this boiler water softening device includes a housing 1, a first chamber 2, a second chamber 3, a filter box 4, a Y-type filter 5, a first valve 6, a water distribution pipe 7, a water distributor 8, a chute 9, a water pump 10, a brine tank 11, a brine pipe 12, a first float switch 13, a filter head 14, a brine bypass pipe 15, a second valve 16, a chamber connecting pipe 17, a third valve 18, a salt filling window 19, a water supply pipe 20, a second float switch 21, a blowdown detection pipe 22, a fourth valve 23, a fifth valve 24, a second chamber outlet pipe 25, an inspection door 26, a water distribution hole 27, and a partition 28.

[0033] Reference Appendix Figure 1A partition 28 is installed inside the housing 1 (preferably in the lower middle part) to form a first chamber 2 above the partition 28 and a second chamber 3 below the partition 28. The first chamber 2 and the second chamber 3 are not directly connected, but are connected through a chamber connecting pipe 17 installed on the outside of the housing 1. Preferably, a third valve 18 is installed on the chamber connecting pipe 17 (to control the opening and closing of the chamber connecting pipe 17). The upper end of the chamber connecting pipe 17 is connected to the bottom of the first chamber 2 and is located between the filter box 4 and the partition 28, while the lower end of the chamber connecting pipe 17 is connected to the bottom of the partition 28.

[0034] Furthermore, grooves 9 are provided on the inner walls of both sides of the first chamber 2, and a filter box 4 is slidably installed in the grooves 9. The filter box 4 and the grooves 9 form a softening assembly. Preferably, the shape of the grooves 9 matches the outer contour of the filter box 4 to achieve drawer-type installation. The filter box 4 includes a box body and a cover plate, both of which are made of activated carbon filter plates. The box body is filled with ion exchange resin to absorb calcium and magnesium ions in the water.

[0035] like Figure 1 , 3 As shown, one end of the water distribution pipe 7 is connected to the boiler water (hard water), and the other end of the water distribution pipe 7 passes through the first chamber 2 and is connected to the water distributor 8 located above the filter box 4. Preferably, a plurality of water distribution holes 27 are evenly opened on the water distributor 8 to distribute water evenly to the filter box 4. A Y-type filter 5 and a first valve 6 (which control the opening and closing of the water distribution pipe 7) are also installed on the water distribution pipe 7. The Y-type filter 5 is located on the inlet side of the boiler water to perform a first filtration, avoiding internal contamination and clogging of the water softening device and extending the service life of the water softening device.

[0036] In addition, a second chamber outlet pipe 25 is connected to the bottom of the second chamber 3, and the other end of the second chamber outlet pipe 25 is connected to the boiler to discharge the water in the second chamber 3 into the boiler. A sewage discharge detection pipe 22 is also connected to the bottom of the first chamber 2, and the sewage discharge detection pipe 22 is located between the filter box 4 and the partition 28. A fourth valve 23 is installed on the sewage discharge detection pipe 22 (to control the opening and closing of the sewage discharge detection pipe 22). The second chamber outlet pipe 25 is connected to the bottom of the second chamber 3, and a fifth valve 24 is installed on the second chamber outlet pipe 25 (to control the opening and closing of the second chamber outlet pipe 25).

[0037] Reference Appendix Figure 2 An inspection door 26 is provided on the back of the housing 1 at a position corresponding to the first chamber 2. The width of the inspection door 26 is greater than the width of the filter box 4 and less than the width of the housing 1. The height of the inspection door 26 is greater than the sum of the heights of the softening component and the water distributor 8. When the inspection door 26 is opened, the filter box 4 and the water distributor 8 are exposed, making it easy to pull out the filter box 4 for replacement.

[0038] Furthermore, such as Figure 1 As shown, a brine tank 11 is installed on the outside of the housing 1. The brine tank 11 is connected to the first chamber 2 via a brine pipe 12. A water pump 10 is installed on the brine tank 11, and the water pump 10 is connected to the brine pipe 12 to add brine to the first chamber 2. Preferably, a first float switch 13 is installed at one end of the brine pipe 12 that extends into the first chamber 2, and the first float switch 13 is located above the filter box 4; a filter head 14 is installed at one end of the brine pipe 12 that extends into the brine tank 11. A brine bypass pipe 15 is installed in the middle of the brine pipe 12, and the other end of the brine bypass pipe 15 is connected to the brine tank 11. A second valve 16 is installed on the brine bypass pipe 15 (to control the opening and closing of the brine bypass pipe 15). A salt filling window 19 is opened at the top of the brine tank 11, and a water supply pipe 20 is installed on the brine tank 11 below the salt filling window 19. A second float switch 21 is installed at one end of the water supply pipe 20 that extends into the brine tank 11.

[0039] The working process of this utility model:

[0040] In use, the first valve 6 is opened, and the hard water to be softened is initially filtered through the Y-type filter 5 from the inlet of the water distribution pipe 7, and then evenly sprayed by the water distributor 8 onto the softening component (above the filter box 4). The filter box 4 performs secondary adsorption of impurities in the hard water through the top plate and the box body. The ion exchange resin in the filter box 4 exchanges with the calcium and magnesium ions in the hard water, so that the hard water flowing through the ion exchange resin is softened. The softened water first enters the second chamber 3 through the chamber connecting pipe 17, and then flows into the boiler through the outlet pipe 25 of the second chamber.

[0041] Salt water is added to the first chamber 2 via the salt water tank 11. When the required water level is reached and the softening components are submerged, the first float switch 13 closes, and excess salt water flows back to the salt water tank 11 through the salt water bypass pipe 15 in the middle of the salt water pipe 12. When the water level in the salt water tank 11 is low, the second float switch 21 opens, automatically replenishing the salt water tank 11. When the water level rises to a certain level, the second float switch 21 closes, stopping the replenishment.

[0042] In addition, water is periodically drawn from the sewage detection pipe 22 and the water quality is tested using a hardness indicator. When the hardness of the filtered water is not up to standard, the third valve 18 at the chamber connection pipe 17 is closed, and the water pump 10 at the brine tank 11 is started to add brine to the first chamber 2 until it covers the softening component. The brine is used to reduce the ion exchange resin, so that the ion exchange resin can restore its ion exchange capacity, that is, restore its softening function. The treated waste liquid is discharged from the sewage detection pipe 22.

[0043] After prolonged use, the inspection door 26 can be opened to remove the filter box 4 from the softening assembly, and the ion exchange resin inside can be inspected and replaced.

[0044] In addition, when the amount of soft water salt blocks in the brine tank 11 is low, soft water salt can be added through the salt addition window 19 at the top of the brine tank 11.

[0045] It is understood that, for those skilled in the art, any equivalent substitutions or modifications to the technical solutions and inventive concepts of this utility model should fall within the protection scope of the appended claims.
