TECHNICAL FIELD

[0001] The present application relates to the technical field of softening water treatment device, in particular to a softening water treatment device of induced crystallization granulation fluidized bed. BACKGROUND

[0002] In the scenes of industrial circulating cooling water system, mine wastewater reuse, high salinity groundwater purification, etc., the softening treatment of high hardness water is the key link to ensure the stable operation of the system. The Ca 2+ , Mg 2+ ions rich in high hardness water can cause a series of problems: in the industrial circulating cooling system, calcium and magnesium ions can form hard scale on the surface of the heat exchanger, which can reduce the heat exchange efficiency by more than 30%, and shorten the equipment maintenance period to 1 / 3 of the traditional operation state. If the high hardness water in the mine wastewater scene is directly discharged, it will cause soil hardening, and if it is reused, it will easily block the pipeline and equipment, which seriously restricts the recycling of water resources. The existing high hardness water softening technology has obvious limitations: the chemical precipitation method needs to add a large amount of reagent, and 5-10 kg of sludge will be produced for every cubic meter of high hardness water treated, which has high subsequent sludge disposal cost and is easy to cause secondary pollution. Ion exchange method relies on resin adsorption, and the regeneration frequency of resin increases significantly in high hardness water environment, which not only consumes a large amount of regeneration reagent, but also produces high-salt wastewater, increasing the processing difficulty. The traditional electrochemical softening device is prone to crystallization and deposition on the surface of the cathode, and the hardness removal efficiency will decrease to less than 50% after 100 hours of operation. In addition, the utilization rate of crystal grains in the device is less than 60%, which is difficult to meet the continuous and stable treatment needs of high hardness water.

[0012] Compared with the prior art, the present application has the beneficial effects that: 1. The present invention strengthens the fluidization of grains through synchronous multi-dimensional excitation to solve the problem of local reaction dead corners. Traditional softening water treatment devices often cause reaction dead zones in local areas due to uneven fluidization of grains, insufficient contact between calcium and magnesium ions and grains, and low removal efficiency. The present invention constructs a vertical and horizontal composite excitation mechanism through the linkage and coordination of the excitation system and the synchronization system. In the excitation system, the servo motor drives the half-tooth gear to cooperate with the return spring to realize high-frequency vertical reciprocating motion of the vertical vibration frame. The synchronization system converts the vertical motion into horizontal motion of the translation frame through precise transmission of the synchronous rack, synchronous gear and transmission toothed belt, so that the microfiltration cartridge obtains vertical vibration and horizontal disturbance at the same time. This synchronous multi-dimensional excitation breaks the sedimentation inertia of the grains and expands the movement trajectory of the grains. Compared with traditional static or single-direction vibration structures, the effective contact area between the grains and calcium and magnesium ions in water is increased, the induced crystallization reaction rate is accelerated, the calcium and magnesium ion removal rate is improved, and local reaction dead corners are eliminated; 2. Due to insufficient mass transfer, existing devices are prone to localized excessive supersaturation, resulting in amorphous precipitation and scattered distribution of crystalline particle size. The present invention designs a coaxial counter-rotating structure for the microfiltration cartridge and the insulating shaft. The transmission shaft drives the driven bevel gears on both sides through the transmission bevel gear, causing the microfiltration cartridge and the insulating shaft to rotate in the opposite direction, forming a high-intensity shear flow field in the gap between the two. This flow field, on the one hand, breaks up bubble aggregates and promotes the rapid separation of H2 bubbles in the cathode area, and on the other hand, accelerates the H2 in the anode area. + , ClO - Diffusion to the cathode region, pushing the cathode region OH - The uniform distribution of carbonate ions and the complex turbulent field generated by synchronous excitation reduce the pH distribution deviation in the device and improve the concentration of crystal particle size distribution, effectively solving the problems of low crystallization efficiency and uneven particle size in traditional devices and ensuring the stability of crystal sedimentation separation. 3. The microfiltration holes and diversion holes of traditional devices are easily clogged due to the adhesion of crystal particles, requiring frequent shutdowns for cleaning and high maintenance costs. The present invention constructs a dual anti-clogging mechanism through multi-system linkage. The high-frequency mechanical vibration generated by synchronous multi-dimensional excitation continuously acts on the surface of the microfiltration cartridge, causing tiny crystal particles attached to the surface of the microfiltration pores to fall off. The counter-rotation of the microfiltration cartridge and the insulating shaft generates water shear force, further stripping impurities from the filter pores. At the same time, the periodic pressure changes caused by the synchronous movement can dredge residual impurities in the diversion holes and microfiltration pores. Combined with the precise pore size design of the microfiltration pores of 10-100μm, the coordinated anti-clogging effect of vibration, shear stripping, and pressure dredging is achieved. 4、The prior art is easy to lose with the water flow, and the regeneration treatment efficiency is low, which leads to high cost of crystal seed supplement, the closed loop regeneration system of crystal separation, cleaning, activation and reflux is constructed through the linkage of the cleaning conveying system and the separation filter core, the large particle crystal grains enter the material lifting pipe through the recovery pipe, the spiral lifting blade realizes the separation of the crystal grains and the liquid through the liquid leakage hole, the 90 DEG C high temperature cleaning liquid in the regeneration pipe cooperates with the spiral conveying blade to stir, efficiently removes the impurities on the surface of the crystal grains, the 400 DEG C heating jacket activates the crystal lattice activity, the arc-shaped ring-shaped separation filter core accurately intercepts the small crystal grains, and returns to the reaction zone through the crystal reflux pipe, the system significantly improves the recycling rate of the crystal grains, greatly reduces the crystal seed supplement amount, and effectively reduces the operation cost; 5、The traditional device is fixed in position, the excitation strength is not adjustable, the water hardness fluctuation adaptability is poor, and the treatment effect is unstable, the dynamic adaptation is realized through the cooperation of the adjusting system and the excitation system, the adjusting push rod can accurately control the axial position of the anode rod through the adjusting frame, the exposed area of the anode is changed to adjust the electrolysis reaction strength, the servo motor of the excitation system can adjust the excitation amplitude and frequency in real time, within the specified fluctuation range of the water hardness, the crystallization reaction stability is maintained by strengthening the fluidization and mass transfer efficiency of the crystal grains.

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0016] like Figures 1-10 As shown, an induced crystallization granulation fluidized bed softening water treatment device includes a cylinder 1, an excitation system is installed on the cylinder 1, the excitation system is connected to a vertical vibration frame 2 that can vertically reciprocate, a translation frame 3 is slidably connected to the vertical vibration frame 2, a synchronization system is provided on the vertical vibration frame 2 for driving the vertical vibration frame 2 and the translation frame 3 to synchronously move, and a transmission shaft 4 that can alternately rotate forward and reverse is connected to the synchronization system; The excitation system includes a back frame 21 mounted on the cylinder 1, a servo motor 22 mounted on the back frame 21, a half-tooth gear 23 mounted on the output shaft end of the servo motor 22, a reciprocating toothed plate 45 drivingly connected to the half-tooth gear 23 mounted on the vertical vibration frame 2, the vertical vibration frame 2 and the back frame 21 being slidably connected, and two return springs 24 mounted on the bottom surface of the vertical vibration frame 2, the other ends of the two return springs 24 being fixedly connected to the back frame 21; The synchronization system includes a synchronization rack 25 mounted on the vertical vibration frame 2, a synchronization shaft 26 rotatably connected to the back frame 21, and a tensioning block 27 slidably connected to the back frame 21. The synchronization shaft 26 is mounted with a synchronization gear 28 that meshes with the synchronization rack 25. The side of the tensioning block 27 is mounted with a tensioning spring 29 limited by the back frame 21. A tensioning pulley 30 is rotatably mounted on the tensioning block 27. Two reciprocating screws 31 are rotatably mounted on the vertical vibration frame 2. A first transmission toothed belt is installed on the synchronization shaft 26. A reciprocating screw 31 and the tensioning pulley 30 are both transmission-connected to the first transmission toothed belt. The first transmission tooth belt is sequentially wound around the pulley on the synchronous shaft 26, the tension pulley 30 and the pulley of the reciprocating screw rod 31; Due to the up-down reciprocating mode of the synchronous rack 25, the synchronous shaft 26 and the transmission shaft 4 are alternately reversed; The hollow sleeve shaft 32 is rotatably installed on the vertical vibration frame 2, the two reciprocating screw rods 31 are connected through the second transmission tooth belt, the hollow sleeve shaft 32 is in transmission connection with the second transmission tooth belt, and the transmission shaft 4 is rotatably installed on the translation frame 3 and connected with the hollow sleeve shaft 32.

[0017] The inside of the hollow sleeve shaft 32 is fixedly provided with a through groove with two open ends and in sliding connection with the transmission shaft 4, the cross sections of the through groove and the transmission shaft 4 are regular polygons, the inside of the insulating shaft 6 is provided with two symmetrically arranged transmission guide grooves, and the anode rod 8 is provided with a guide strip in sliding connection with the transmission guide grooves at positions corresponding to the two transmission guide grooves; When the servo motor 22 drives the half-tooth gear 23 to rotate, intermittent meshing transmission is formed between the half-tooth gear 23 and the vertical vibration frame 2, and the elastic reset action of the reset spring 24 can drive the vertical vibration frame 2 to realize high-frequency vertical reciprocating motion; Through the meshing transmission between the synchronous rack 25 and the synchronous gear 28, the linear motion of the vertical vibration frame 2 is converted into the rotary motion of the synchronous shaft 26, and then the reciprocating screw rod 31 and the hollow sleeve shaft 32 are connected through the transmission tooth belt, so that the vertical excitation and the horizontal excitation are accurately synchronized; The cooperation between the tension pulley 30 and the tension spring 29 ensures the stable transmission of the transmission tooth belt, and the sliding connection between the regular polygon through groove and the transmission shaft 4 ensures the power transmission while being compatible with the excitation displacement; The synchronous excitation motion of the vertical vibration frame 2 and the translation frame 3 can strengthen the flow state of the crystal grains and improve the reaction efficiency; The synchronous multi-dimensional excitation transmits the multi-dimensional excitation force to the micro filter cartridge 5 and the internal crystal grains, so that the crystal grains form a uniform and high-strength suspended flow state in the cathode reaction zone, the up-down pulsation generated by the vertical excitation can break the crystal grain sedimentation inertia and avoid local accumulation; The horizontal disturbance formed by the horizontal excitation expands the crystal grain motion track and increases the collision contact probability with calcium and magnesium ions in water. Compared with the traditional static or single-direction vibration structure, the synchronous motion increases the effective contact area of the crystal grains with the scale-forming ions, accelerates the crystallization reaction rate, improves the removal rate of calcium and magnesium ions, and solves the problem of local reaction dead zone caused by uneven crystal grain flow in the traditional device; On the other hand, the synchronous reciprocating motion optimizes the mass transfer conditions and promotes the crystallization balance. The synchronous excitation drives the water flow to form a complex turbulent flow field, which on the one hand accelerates the diffusion of H + , ClO - , etc. generated in the anode area to the cathode area, and on the other hand promotes the diffusion of OH -The dynamic mass transfer environment reduces the pH value distribution deviation in the device, the crystal particle size distribution is more concentrated, the low crystallization efficiency and uneven particle size caused by insufficient mass transfer in the traditional device are solved, and the stability of crystal grain sedimentation and separation is improved; At the same time, the synchronous reciprocating motion can enhance the self-cleaning ability and reduce the risk of fouling. The vertical and horizontal combined excitation force continuously acts on the surface of the micro filter cartridge 5. Through high-frequency mechanical vibration, the small crystal particles attached to the surface of the micro filter hole are detached. Combined with the water flow shear force generated by the rotation of the micro filter cartridge 5, a double anti-blocking mechanism is formed. The periodic pressure change generated by the synchronous motion can also dredge the residual impurities in the guide hole 43 and the micro filter hole, avoiding the blockage of the hole. The synchronous reciprocating motion is suitable for water quality fluctuations and improves the operation stability. The strength of the synchronous excitation can be adjusted by the servo motor 22. When the water hardness fluctuates, the excitation amplitude can be increased to strengthen the crystal grain fluidization and mass transfer efficiency, ensuring that the crystallization reaction efficiency is not affected by water quality changes. The micro filter cartridge 5 is rotatably installed on the translation frame 3. The micro filter cartridge 5 is rotatably installed in the micro filter cartridge 5. The micro filter cartridge 5 and the micro filter cartridge 5 are both driven by the transmission shaft 4 and coaxially rotate in opposite directions. The micro filter cartridge 5 and the micro filter cartridge 6 are both installed with driven bevel gears. The transmission shaft 4 is installed with a transmission bevel gear. The two driven bevel gears are both in transmission connection with the transmission bevel gear. The two driven bevel gears are respectively arranged on both sides of the transmission bevel gear. The transmission shaft 4 drives the two driven bevel gears on both sides through the transmission bevel gear, realizing the coaxial opposite rotation of the micro filter cartridge 5 and the micro filter cartridge 6. The coaxial opposite rotation of the micro filter cartridge 5 and the micro filter cartridge 6 can strengthen the interface shear and mass transfer efficiency. The opposite rotation of the micro filter cartridge 5 and the micro filter cartridge 6 forms a high-strength shear flow field in the gap between them. The water flow shear force is significantly improved compared to the one-way rotation structure. This shear effect can break up gas bubble aggregates in the water body, promote the rapid detachment of H2 gas bubbles generated in the cathode reaction zone from the liquid surface, and avoid the blocking of gas bubbles from contacting the crystal grains and ions. On the other hand, it accelerates the diffusion of H + , ClO - to the cathode area, and pushes OH - and carbonate ions to the cathode area, making the distribution of carbonate ions uniform, improving the ion diffusion coefficient in the device compared to the traditional device, and solving the problem of local reaction lag caused by uneven mass transfer in the traditional one-way rotation structure. At the same time, the opposite rotation of the micro filter cartridge 5 and the micro filter cartridge 6 can improve the self-cleaning ability of the micro filter structure. The bidirectional water flow generated by the opposite rotation can effectively strip the small crystal particles attached to the surface of the filter hole. And the reverse rotation of the micro filter cartridge 5 and the insulating shaft 6 can optimize the crystal grain fluidization and crystallization environment. The rotation of the micro filter cartridge 5 drives the water flow in the outer cathode area to form a circulating flow, and the rotation of the insulating shaft 6 generates an inner water flow, which forms a reverse disturbance, so that the crystal grains are in a three-dimensional suspended state in the composite flow field, and the fluidization uniformity is improved; This dynamic environment avoids the accumulation of crystal grains on the cylinder wall, while promoting moderate collisions between crystal grains, accelerating the growth and agglomeration of crystalline particles; Further, the reverse rotation of the micro filter cartridge 5 and the insulating shaft 6 can enhance the electrolysis reaction synergy. The reverse rotation makes the water flow in the anode and cathode reaction areas form a closed loop circulation. The HClO and other oxidizing substances generated in the anode area can oxidize and decompose organic impurities in the water when entering the cathode area, reducing the coverage of organic matter on the active sites of the crystal grains, and improving the retention rate of the crystal grain induction activity. At the same time, the bidirectional rotation enhances the water electrolysis efficiency; The micro filter cartridge 5 is uniformly distributed with micro filter holes, and the micro filter cartridge 5 is installed with a plurality of flow guide rings 7 arranged in a linear array; The flow guide ring 7 is uniformly distributed with flow guide holes 43, and the cross section of the flow guide ring 7 is isosceles trapezoidal.
