Description

Technical Field

[0002] As an indispensable and important equipment in industrial production, the operating efficiency and safety of the boiler are directly related to the stability and economic benefits of the entire production system. However, during the operation of the boiler, if the water quality is not properly treated, it is very easy to scale on the heating surface, resulting in reduced heat transfer performance of the furnace wall, increased fuel consumption, and even causing safety accidents such as corrosion and explosion. Therefore, softening the boiler water supply to remove hardness ions such as calcium and magnesium in the water has become a key link in ensuring the safe and efficient operation of the boiler.

[0003] At present, there are many boiler water softening equipment on the market, which mainly work based on the principle of ion exchange. These equipments use the cation exchange resin in the resin layer to exchange the calcium and magnesium ions in the water with the sodium ions on the resin, thereby softening the water. However, the existing technology still has some shortcomings in practical applications:

[0006] 3. Insufficient flushing and dissolving capacity: During the flushing process, some equipment has insufficient flushing and dissolving capacity due to uneven flushing liquid concentration or unreasonable flushing method, which cannot effectively remove dirt and residual salt on the resin, affecting the long-term stable operation of the equipment.

[0035] Example

[0036] Please refer to Figure 1-Figure 6 The present embodiment provides a water softening system, comprising: at least two water softening components 1, any one of the water softening components 1 comprises a softening tank 101, a water inlet pipeline 102, a water softening resin 103 and a water outlet pipeline 104, the water inlet pipeline 102 and the water outlet pipeline 104 are both connected to the softening tank 101, the water softening resin 103 is arranged in the softening tank 101, and the water to be softened entering the softening tank 101 flows to the input end of the water outlet pipeline 104 after being adsorbed by the water softening resin 103; a resin regeneration component 2, the resin regeneration component 2 is used to generate a saturated salt solution, any one of the softening tanks 101 is provided with a salt water pipeline 4 for inputting the saturated salt solution, and a plurality of salt water pipelines 4 are connected to the resin regeneration component 2; a control component 3, the control component 3 is used to control the flow of the solution between the water softening component 1 and the resin regeneration component 2.

[0037] In this embodiment, the water softening component 1 is used to adsorb calcium and magnesium ions in the input tap water, so as to soften the water, facilitate transportation into the boiler for direct use, reduce the generation of scale in the boiler, improve the heat transfer performance of the furnace wall, and avoid safety accidents such as corrosion and explosion. The water softening component 1 uses multiple components that can soften at the same time. When the resin is regenerated, another water softening component 1 can be used to ensure that softened water continues to be added to the boiler, which can ensure that the boiler is used without stopping. Specifically, the softening tank 101 is used to load softening resin for softening the water, the water inlet pipeline 102 is used to transport the water to be softened, and the water outlet pipeline 104 is used to output softened water that has been adsorbed by the softening resin for calcium and magnesium ions, so as to facilitate the use of the boiler water.

[0038] In this embodiment, the resin regeneration component 2 is used to generate a regeneration liquid, and the regeneration liquid is used to flush the soft water resin 103 after adsorbing calcium and magnesium ions, and the calcium and magnesium ions undergo a replacement reaction with the saturated salt solution. After the regeneration is completed, the resin can be put back into use for ion exchange, which can effectively reduce costs and improve resource utilization. Specifically, the brine pipeline 4 is used to input the saturated salt solution generated by the resin regeneration component 2, which is convenient for the transportation of the saturated salt solution.

[0039] In this embodiment, the control component 3 is used to set the operating parameters of the entire water softening system to facilitate the coordinated action of various electrical components.

[0040] Please refer to Figure 1-Figure 3 In some implementations of the present embodiment, a filter plate 5 is provided in the softening tank 101, and there are two filter plates 5. A filling gap for accommodating the water softening resin 103 is formed between the two filter plates 5. A clean water cavity 6 and a sewage collecting cavity 7 are formed between the two filter plates 5 and the softening tank 101 respectively. The water inlet pipeline 102 enters from the top of the softening tank 101 and passes through the filter plate 5, the water softening resin 103 and the filter plate 5 at the bottom in sequence to the sewage collecting cavity 7. A sewage discharge pipeline 8 connected to the sewage collecting cavity 7 is provided at the bottom of the softening tank 101. The water outlet pipeline 104 is connected to the clean water cavity 6. The multiple water outlet pipelines 104 are all used to be connected to the water inlet of the boiler.

[0041] In this embodiment, the filter plate 5 is used to form a filling gap for filling the water softening resin 103, which is convenient for the stable adsorption of calcium and magnesium ions in the tap water. In addition, the filter plate 5 can also be used to filter particulate impurities and suspended matter in the tap water to improve the cleanliness of the water. The water purification chamber 6 is used to temporarily store the softened water, and the softened water flows to the boiler body through the outlet pipe 104. The sewage collection chamber 7 is used to receive the filtered particulate impurities and suspended matter, which fall into the sewage collection chamber 7 due to gravity. It should be noted that fine particulate impurities can be blocked on the filter plate 5 at the bottom of the soft water tank. During regeneration, a saturated salt solution is input through the top of the soft water tank, and the filter plate 5 is reversely flushed from top to bottom, and the impurities attached to the filter plate 5 can be flushed into the sewage collection chamber 7, so that the softening tank 101 can be cleaned by a saturated salt solution during resin regeneration, which greatly improves its convenience of use. In addition, there is no need to add a separate filtering device during the water softening process, which greatly reduces the cost of use and improves the convenience of use. The sewage pipe 8 is in an open state when the resin is regenerated and in a closed state when the water is softened, so as to directly discharge the replaced saturated salt solution and impurities during the resin regeneration, facilitate subsequent centralized treatment, and improve the convenience of use.

[0042] Please refer to Figure 1-Figure 6 In some implementations of the present embodiment, the resin regeneration component 2 includes a reaction container 201, a raw material adding mechanism 202 and a stirring member 203. The raw material adding mechanism 202 is arranged on the reaction container 201, and the output end of the raw material adding mechanism 202 is connected to the reaction container 201. The stirring member 203 is arranged on the reaction container 201. A regeneration pipeline 9 connected to the brine pipeline 4 is arranged at the bottom of the reaction container 201, and a first solenoid valve 10 is connected in series on the regeneration pipeline 9.

[0043] In this embodiment, the reaction vessel 201 is used as a reactor for configuring a saturated salt solution. By adding a certain amount of water and solid salt to the reaction vessel 201, a saturated salt solution suitable for a replacement reaction with the water softening resin 103 can be quickly configured through the homogenization effect of the stirring member 203. The raw material adding mechanism 202 is used to quantitatively add granular salt to the reaction vessel 201 according to the volume of the salt particles set by the control component 3, so as to facilitate the configuration of a saturated salt solution of a suitable concentration and facilitate the subsequent replacement reaction with the water softening resin 103. The regeneration pipeline 9 is used to output the salt solution, and the first solenoid valve 10 is used to control the opening and closing of the regeneration pipeline 9, and control the output of the configured saturated salt solution according to the regeneration demand of the water softening resin 103.

[0044] Please refer to Figure 4-Figure 6In some implementations of this embodiment, the raw material adding mechanism 202 includes a grinding piece 2021 and a quantitative feeding piece 2022 . The quantitative feeding piece 2022 is disposed on the reaction container 201 , and the grinding piece 2021 is disposed on the quantitative feeding piece 2022 .

[0045] In this embodiment, the grinding member 2021 is used to grind large particles of industrial salt or agglomerated industrial salt into fine particles, which is convenient for the rapid preparation of saturated salt solution. Large particles or agglomerated industrial salt are difficult to measure accurately, which easily causes the concentration of the prepared saturated salt solution to deviate from the preset value. The quantitative feeding member 2022 is used to deliver the corresponding industrial salt particles according to the preset parameters of the control component 3, so as to quickly obtain the saturated salt solution through the stirring member 203.

[0046] Please refer to Figure 1 and Figure 2 In some implementations of this embodiment, a pressure gauge is provided at the bottom of the softening tank 101 , and the press 11 is used to monitor the pressure in the sewage collecting chamber 7 .

[0047] In this embodiment, the pressure gauge is used to monitor the pressure in the softening tank 101. When the filter plate 5 is clogged with small particles after a long period of use, its filtering effect decreases, so that the pressure in the sewage chamber increases. When the pressure monitored by the pressure gauge coincides with or exceeds the safety value preset by the control component 3, the corresponding water softening component 1 is automatically controlled to input the water solution pipeline to close, thereby regenerating the soft water resin 103 and backwashing the filter plate 5 at the bottom, so as to improve the safety and convenience of the entire water softening system.

[0048] Please refer to Figure 1 and Figure 2 In some implementations of this embodiment, a booster pump 12 for increasing the flow pressure of the saline solution is provided between the first solenoid valve 10 and the saline pipeline 4 .

[0049] In this embodiment, the booster pump 12 is used to increase the pressure of the brine pipe 4. Due to the low position of the water source, the water flow pressure is insufficient, which affects normal use. The booster pump 12 increases the water flow pressure to ensure that the water can be smoothly transported to the top of the soft water tank. At the top of the soft water tank, due to the gravity of the water body and the pressurization of the booster pump 12, the water body is under high pressure and reaches the filter plate 5.

[0050] Please refer to Figure 4 and Figure 5In some implementations of the present embodiment, the above-mentioned quantitative feeding member 2022 includes a conical bucket 20221, a quantitative cylinder 20222 and a conveying auger 20223, the quantitative cylinder 20222 is arranged at the output end of the conical bucket 20221, the conveying auger 20223 is rotatably arranged on the conical bucket 20221, and the conveying auger 20223 is located in the quantitative cylinder 20222, the blades of the conveying auger 20223 are abutted against the inner side wall of the quantitative cylinder 20222, and the conical bucket 20221 is provided with a driving motor 13 for driving the conveying auger 20223 to rotate.

[0051] In this embodiment, the conical bucket 20221 is used to temporarily store industrial salt particles that have been ground into powder. The salt powder is sequentially transported into the metering cylinder 20222 and the reaction container 201 by the rotation of the conveying auger 20223. The control component 3 controls the quantitative entry of the powdered material by controlling the number of rotations of the conveying auger 20223, so as to facilitate the delivery of a quantitative amount of salt powder according to the water intake, so as to ensure that the concentration of the prepared salt solution is suitable for exchanging the calcium and magnesium ions on the softening resin 103.

[0052] Preferably, the drive motor 13 is a servo motor, which is an engine that controls the operation of mechanical components in a servo system and is an auxiliary motor indirect speed change device. The servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal into torque and speed to drive the control object. Its excellent control accuracy is an ideal material for the drive motor 13, but it is not limited to the above-mentioned servo motor material, and can also be other materials with similar performance.

[0053] Please refer to Figure 4-Figure 6 In some implementations of the present embodiment, the grinding member 2021 includes a guide shell 20211, a grinding cylinder 20212 and a grinding roller 20213. The guide shell 20211 is sleeved on the grinding cylinder 20212. A guide gap 16 is provided between the guide shell 20211 and the grinding cylinder 20212. The grinding roller 20213 is rotatably arranged in the grinding cylinder 20212. A temporary storage hopper 14 connected to the grinding cylinder 20212 is arranged on the guide shell 20211. A salt delivery pipeline 15 is arranged on the end of the guide shell 20211 away from the temporary storage hopper 14. The salt delivery pipeline 15 is respectively connected to the guide gap 16 and the conical hopper 20221.

[0054] In this embodiment, the guide shell 20211 is used to guide the ground salt powder, and the grinding cylinder 20212 has a plurality of through holes for passing the ground salt powder through the guide gap 16 between the guide shell 20211 and the grinding cylinder 20212 to the salt delivery pipeline 15, so that the salt powder enters the conical bucket 20221, which is convenient for subsequent accurate metering and output. The temporary storage hopper 14 is used to temporarily store industrial salt raw materials. When the raw materials in the conical bucket 20221 are insufficient, the industrial salt is driven by the grinding element 2021 to be ground into powder and enter the conical bucket 20221. The grinding roller 20213 is used to grind coarse industrial salt particles. The large particles are continuously ground into small particles through the extrusion between the grinding roller 20213 and the grinding cylinder 20212, so as to facilitate the metering and delivery of industrial salt powder and the dissolution of salt powder, and prevent undissolved particles from entering the softening tank 101.

[0055] Please refer to Figure 1 and Figure 2 In some implementations of this embodiment, a tap water input pipeline 17 is provided on the reaction container 201 , and a second solenoid valve 18 is connected in series to the tap water input pipeline 17 .

[0056] In this embodiment, the tap water input pipeline 17 is used to add tap water into the reaction container 201, and the flow of water is controlled by the second solenoid valve 18, so that the volume of tap water entering is controlled by controlling the time of tap water entering, thereby facilitating the metering of water delivery and quantitatively preparing the volume of saturated salt solution according to the required quantity for use.

[0057] Please refer to Figure 1 and Figure 2 In some implementations of this embodiment, the control component 3 includes a control panel, which is electrically connected to the water softening component 1 and the resin regeneration component 2 respectively.

[0058] In this embodiment, the control panel is used to set the working parameters of each electronic component, so as to facilitate the automatic operation of the entire water softening system and enhance the intelligence of the water softening system.

[0059] When in use, the operating parameters of each electronic component are set through the control panel, the industrial salt raw material is poured into the temporary storage hopper 14 of the grinding piece 2021, and the coarse industrial salt particles are ground into industrial salt powder by driving the grinding roller 20213 to rotate and enter the conical bucket 20221, and the conveying auger 20223 in the conical bucket 20221 is driven to rotate so that the salt powder is filled into the metering cylinder. When the ability of the softening resin particles in the water softening tank 101 to absorb calcium and magnesium ions is significantly reduced, the second solenoid valve 18 is controlled to open, and a preset volume of tap water is conveyed. According to the volume of tap water, the conveying auger 20223 is driven to rotate a preset parameter amount of salt powder, and the stirring is driven. After the component 203 mixes the salt powder and the tap water to homogenize, the first solenoid valve 10 and the booster pump 12 are opened, and the saturated salt solution enters the clean water chamber 6, passes through the upper filter plate 5, the softening resin 103 and the lower filter plate 5 from top to bottom in turn, and the sewage of the reverse-washing filter plate 5 enters the sewage collecting chamber 7, and then flows out through the sewage discharge pipe; when softening the water, the tap water is transported through the water inlet pipe, the tap water enters the sewage collecting chamber 7, and the filter plate 5 at the bottom filters the tap water and then enters the softening resin. The softening resin absorbs the calcium and magnesium ions in the water, and the softened water enters the clean water chamber 6 through the upper filter plate 5, and finally enters the boiler through the outlet pipe 104 for use.

[0060] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
