In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0034] In order to solve the problem of ion impurity removal in high-salinity wastewater, the traditional three-tank system mainly relies on the flocculation and sedimentation process, and removes various metal ions by adding corresponding reagents. However, in the operation of the three-tank system, although the rapid mixing in the coagulation stage and the subsequent long-term static sedimentation are helpful for the formation of initial flocs, they are not conducive to the growth of chemical crystals, because the long-term static state leads to the lack of necessary collision opportunities for the crystals, thus affecting their growth and the final sedimentation and separation efficiency.

[0035] In order to solve this problem, the present invention provides a new solution. Figure 1-Figure 9 The structure and working principle of the present invention are described.

[0036] Reference Figure 1The present invention provides a room temperature crystallization reaction device including a shell 100, a turbulent aeration component 200, a water inlet circulation component 300 and a dosing component 500. The shell 100 has a cavity 180 inside, and a reaction barrel 110 is arranged inside the cavity 180; the turbulent aeration component 200 is arranged inside the cavity 180 and communicated with the reaction barrel 110, and is used to form air flow disturbance and water flow turbulence inside the reaction barrel 110, so as to improve the boiling state of the crystal body at the bottom of the reaction barrel 110 without adhesion, and to be easily discharged through the slag discharge pipe, and at the same time, the turbulence can promote the regular growth of the primary crystals and increase the fluidity of the liquid inside the entire reaction barrel 110; the water inlet circulation component 300 is arranged inside the cavity 180, and is communicated with the end of the turbulent aeration component 200 away from the reaction barrel 110, and is used to input the liquid to be crystallized into the reaction barrel 110; the dosing component 500 is communicated with the reaction barrel 110, and is used to input the reaction material into the reaction barrel 110.

[0037] Specifically, in the above structure, the water inlet circulation component 300 ensures the continuous supply of the liquid to be crystallized. As the liquid to be crystallized enters, the turbulent aeration component 200 starts to operate, generating airflow, so that the liquid in the reaction tube 110 is kept in a dynamic flow state. This dynamic condition not only promotes the rapid distribution of the newly input liquid in the entire reaction space, but also provides sufficient kinetic energy, so that the crystal nuclei or micro-crystals in the solution can collide frequently and gradually grow in the flow. At the same time, the dosing component 500 can add reaction materials to the reaction tube 110, and these materials can be quickly diffused and evenly dispersed under turbulent conditions, providing the necessary chemical environment for the crystallization process, which is conducive to the formation of larger crystals, thereby improving the effect of precipitation separation.

[0038] Secondly, the present invention can maintain a high reaction activity even at room temperature due to the presence of the turbulent aeration component 200. The turbulence effectively prevents the occurrence of local supersaturation, reduces the possibility of amorphous precipitation, and also promotes the growth of crystals, avoiding the aggregation or abnormal growth of small crystals caused by excessive local concentration.

[0039] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the turbulent aeration component 200 includes an aeration component 210 and a plurality of turbulent nozzles 220. The aeration component 210 has an air cavity 212 inside and is provided with an air inlet 211. One end of the air inlet 211 is connected to the air cavity 212, and the other end is connected to the air supply system. The top of the aeration component 210 is provided with a plurality of air outlets 213. The plurality of turbulent nozzles 220 are all provided through the aeration component 210 and are spaced apart from the air outlets 213. One end of the turbulent nozzle 220 is connected to the water inlet circulation component 300, and the other end is connected to the inside of the reaction tube 110. The turbulent nozzle 220 is used to form turbulence inside the reaction tube 110.

[0040] In the above structure, when the air supply system supplies air to the air cavity 212 through the air inlet 211, the gas is uniformly released from the air outlet 213 into the reaction tube 110. At the same time, the water inlet circulation component 300 introduces the liquid to be treated into the turbulent nozzle 220. As the liquid is sprayed into the reaction tube 110 at a high speed, it interacts with the gas released from the air outlet 213, thereby forming a strong turbulent effect inside the reaction tube 110. This turbulence not only improves the fluidity of the liquid, increases the contact and mixing between the various parts of the solution, but also provides more collision opportunities for crystals, thereby promoting their growth and precipitation separation. Turbulence can also make large particles of slag particles into a boiling fluidized state to ensure that they can be well recycled.

[0041] Furthermore, in order to ensure the stability of the structure and facilitate maintenance, corresponding limit holes 214 may be provided at the upper and lower ends of the aeration element 210, and the turbulent nozzles 220 are plugged into these limit holes 214 one by one. This design ensures that the turbulent nozzles 220 are fixed in position to prevent them from shifting or falling off during operation. The turbulent nozzles 220 may be fixedly connected to the limit holes 214, or may be detachably connected to the limit holes 214, depending on the specific application requirements and maintenance convenience. Through such a design, a stable connection between the various components during the operation of the device is guaranteed, and later maintenance and replacement work is facilitated, thereby ensuring the long-term reliable operation of the system.

[0042] When the turbulent nozzle 220 and the limiting hole 214 are fixedly connected, the turbulent nozzle 220 can be firmly installed in the limiting hole 214 by permanent fixing methods such as welding or bonding. When the turbulent nozzle 220 and the limiting hole 214 are detachably connected, it can be achieved by threaded connection or quick connector. The threaded connection is achieved by machining corresponding internal and external threads on the turbulent nozzle 220 and the limiting hole 214. This method not only provides a good sealing effect, but also allows disassembly and assembly without damaging the components, which is convenient for regular maintenance or replacement of damaged parts.

[0043] In order to ensure that liquid does not enter the air cavity 212, a series of measures can be taken when designing the aeration element 210 to achieve effective separation of the gas path and the liquid path.

[0044] Specifically, in order to prevent the backflow of liquid, a one-way valve or a similar anti-backflow device should be provided when designing the air inlet 211. For example, a spring-loaded one-way valve can be installed at the air inlet 211, and such a valve can be automatically closed in the absence of gas pressure, thereby effectively preventing liquid from entering the air cavity 212 through the air inlet 211.

[0045] Secondly, in order to further prevent the liquid from directly impacting the gas outlet 213, the gas flow direction should be reasonably guided when designing the gas outlet 213 at the top of the aeration element 210. Specifically, a baffle or a guide structure can be set near the gas outlet 213 to change the flow path of the liquid and reduce the chance of it directly contacting the gas outlet 213. The design of the baffle can make the liquid sprayed from the turbulent nozzle 220 hit the baffle first, disperse the impact force of the liquid, and guide the gas to be more evenly distributed in the reaction cylinder 110, promote a good gas-liquid mixing effect, and then reduce the risk of liquid entering the gas cavity 212.

[0046] In addition, in order to ensure the sealing and stability of the connection, when designing the limiting holes 214 at the upper and lower ends of the aeration element 210, it should be considered that no liquid will penetrate into the air cavity 212 through the interface even under high pressure conditions. Specifically, an O-ring or other form of sealing device can be provided between the turbulent nozzle 220 and the limiting hole 214. The O-ring made of corrosion-resistant material can not only provide a good sealing effect, but also ensure a stable connection, facilitate disassembly and maintenance, and effectively prevent liquid from invading the air cavity 212, ensuring the long-term stable operation of the system and the convenience of later maintenance.

[0047] Reference Figure 4 In some embodiments of the present invention, the turbulent nozzle 220 includes a flow guide section 221, an expansion section 222 and a nozzle 223. The flow guide section 221 has a circular cross section; the nozzle 223 has a polygonal cross section; the expansion section 222 is connected between the flow guide section 221 and the nozzle 223, and the cross section of the expansion section 222 gradually expands from the end connected to the flow guide section 221 to the end connected to the nozzle 223.

[0048] It should be noted that the drainage section 221, the expansion section 222 and the nozzle 223 can be an integrally formed setting. When the number of turbulent aeration components 200 is determined, it is necessary to do so according to the flow rate. Specifically, the flow rate must be 13.5-20m / s. At the same time, it is necessary to make the length of the drainage section 221 twice or more than the length of the expansion section 222. The width of the nozzle 223 is twice the width of the drainage section 221. The turbulent nozzle 220 can be made of materials that are not easy to scale, such as PP or PVDF.

[0049] In this embodiment, by organically combining the functions of the drainage section 221, the expansion section 222 and the nozzle 223, effective regulation of the liquid flow path is achieved. Specifically, the circular cross-section of the drainage section 221 ensures the smooth inflow of the liquid; the design of the expansion section 222 realizes the energy accumulation and acceleration of the liquid, and increases the kinetic energy of the liquid; and the polygonal cross-section of the nozzle 223 enhances the dispersion and turbulence intensity after injection. Through this series of design measures, the turbulent nozzle 220 can effectively produce a strong turbulent effect in the reaction tube 110, improve the mixing efficiency of the liquid, promote the growth of crystals, and ultimately improve the efficiency and quality of the entire crystallization process.

[0050] In order to ensure that the liquid can smoothly pass through each stage after entering the turbulent nozzle 220, when designing the drainage section 221, its cross section should be kept circular to reduce the resistance when the liquid enters and ensure that the liquid can smoothly enter the expansion section 222. When designing the expansion section 222, its cross section should be gradually expanded from the end connected to the drainage section 221 to the end connected to the nozzle 223, so that the kinetic energy of the liquid can be increased during the process of passing through the expansion section 222, so that the liquid has obtained sufficient speed and energy before reaching the nozzle 223. Finally, when designing the nozzle 223, a polygonal cross section, such as a square or a regular pentagon, should be selected, which helps the liquid to disperse quickly when spraying, forming a wider turbulent area, thereby improving the mixing conditions in the reaction cylinder 110.

[0051] Reference Figure 1 In some embodiments of the present invention, a barrier 120 is further provided inside the cavity 180, and the barrier 120 is sleeved on the outside of the reaction tube 110. Specifically, the barrier 120 and the reaction tube 110 may be coaxially arranged, and the two may be fixedly connected by a connector 150; a first flow channel is provided between the reaction tube 110 and the barrier 120, and a second flow channel is provided between the barrier 120 and the inner wall of the housing 100; the top of the first flow channel is connected to the top of the reaction tube 110, and the bottom of the first flow channel is connected to the bottom of the second flow channel. The bottom of the cavity 180 has a sedimentation area 190, and both the first flow channel and the second flow channel are connected to the sedimentation area 190, and the sedimentation area 190 is used to collect sediment.

[0052] Specifically, when the liquid to be crystallized enters the reaction tube 110, it begins to move upward, and in the process, it chemically reacts with the medicine provided by the medicine adding component 500 to form crystals. Larger particles of crystals and waste residues will settle at the bottom of the reaction tube 110 due to gravity, while smaller impurities and medicines will continue to move upward with the water flow to ensure a more adequate reaction. After reaching the top of the reaction tube 110, the mixed liquid flows into the first flow channel, and then flows from the bottom of the first flow channel to the second flow channel, where it restarts to move upward. Since the bottoms of the first flow channel and the second flow channel are both connected to the sedimentation area 190, any sediment can be gathered in the sedimentation area 190 during the entire liquid circulation process and wait for further processing.

[0053] The present invention realizes multiple circulations of liquid in the reaction cylinder 110 by rationally arranging the reaction cylinder 110, the baffle 120 and the flow channels therebetween. First, the liquid to be crystallized rises in the reaction cylinder 110 and reacts with the drug to form crystals, and the larger crystals and waste residues are directly precipitated to the bottom; then, the mixed liquid passes through the circulation path of the first flow channel and the second flow channel, so that small particles of impurities and incompletely reacted drugs can stay and react for a longer time in the system. All precipitates can be concentrated in the precipitation area 190, and are sucked and circulated into the reaction center cylinder by the precipitate reprocessing component 400 to participate in the reaction of the newly entered liquid and the drug, thereby promoting the growth of crystals.

[0054] Reference Figure 1 In some embodiments of the present invention, an inclined tube sedimentation member 130 is provided at the top of the second flow channel. The inclined tube sedimentation member 130 is used to settle the initially grown fine crystals that are difficult to settle. When the fine crystals accumulated on the inclined tube surface reach a certain thickness, they will settle to the sedimentation area 190 due to their own gravity and re-participate in the crystal growth process. A water collection tank 140 is also provided at the top of the housing 100, and the water collection tank 140 is located above the inclined tube sedimentation member 130.

[0055] When the liquid rises to the top of the second flow channel, it will pass through the inclined tube sedimentation piece 130 for the final step of purification. The presence of the inclined tube sedimentation piece 130 effectively intercepts the remaining small particles of impurities, making the treated liquid purer. Finally, the purified liquid flows into the inclined tube sedimentation piece 130 located above the inclined tube sedimentation piece 130, which is convenient for subsequent collection and processing. Such a design not only optimizes the flow path of the liquid and improves the reaction efficiency, but also ensures the effective collection of the precipitate and the further purification of the liquid through reasonable flow channel layout and shallow sedimentation mechanism.

[0056] Reference Figure 5In some embodiments of the present invention, the inclined tube sedimentation member 130 includes a plurality of inclined plates 131 and a plurality of bearing members 160. The plurality of inclined plates 131 are arranged at intervals, and two adjacent inclined plates 131 are fixedly connected to each other; the plurality of bearing members 160 are welded at intervals between the barrier member 120 and the housing 100, and are located at the bottom of the inclined plates 131, and are used to support the inclined plates 131. In order to improve the sedimentation efficiency, the inclined plates 131 can be provided with multiple layers. A base 170 is also provided at the bottom of the housing 100, and the base 170 is used to support the housing 100.

[0057] In the above structure, a plurality of inclined plates 131 are arranged at intervals, and two adjacent inclined plates 131 are connected to each other to form a continuous but segmented inclined surface. A plurality of bearing members 160 can be arranged at intervals between the barrier member 120 and the housing 100 and located at the bottom of the inclined plate 131 to support the inclined plate 131. This design not only provides a stable support, but also optimizes the flow path and precipitation efficiency of the liquid in the reaction cylinder 110.

[0058] Specifically, the inclined plate 131 allows the liquid to be crystallized that enters the reaction tube 110 to flow slowly along the surface of the inclined plate 131. Due to the presence of the inclined plate 131, the flow path of the liquid is extended, increasing the residence time of the liquid in the reaction tube 110, thereby providing more opportunities for chemical reactions. In this process, larger particles of crystals and waste residues will gradually settle on the inclined plate 131 under the action of gravity, and slide along the inclined plate 131 to the sedimentation area 190 at the bottom. Since the inclined plate 131 is provided with multiple layers, some fine primary crystals can also be precipitated. The bearing member 160 is located at the bottom of the inclined plate 131 and is spaced between the barrier member 120 and the housing 100. These bearing members 160 not only provide the necessary support for the inclined plate 131 to ensure its structural stability, but also prevent the inclined plate 131 from directly contacting the barrier member 120 or the housing 100.

[0059] Reference Figure 6 and Figure 7 In some embodiments of the present invention, the water inlet circulation component 300 includes a circulation box 310 and a Rafale tube 330. The circulation box 310 is provided with a circulation pipe 320, one end of the circulation pipe 320 is connected to the circulation box 310, and the other end is connected to the sedimentation area 190; an opening is provided on the top of the circulation box 310, and the opening is connected to the turbulent aeration component 200 through a connecting pipe 360; the Rafale tube 330 is arranged inside the circulation box 310, one end of the Rafale tube 330 is connected to the water inlet pipe 340, and the other end extends toward the opening direction, and a gap is provided between the opening.

[0060] Specifically, the circulation box 310 can be detachably arranged on the bottom wall of the chamber 180 by bolts, or can be welded to the bottom wall of the chamber 180. The shape of the circulation box 310 can be a cylindrical or rectangular structure, and there is a cavity inside it. The circulation pipeline 320 is fixedly installed on the outer periphery of the circulation box 310, and passes through the side wall of the circulation box 310, and is connected to the cavity inside the circulation box 310. The Rafael tube 330 is fixedly installed on the bottom wall of the circulation box 310, and one end extends to the outside of the circulation box 310, and is connected to the water inlet pipe 340. The water inlet pipe 340 is mainly connected to the supply component of the precipitated liquid, and the precipitated liquid enters the device through the water inlet pipe 340. At the same time, the side of the water inlet pipe 340 is also connected to a dosing pipe 350, and drugs can be added to the inside through the dosing pipe 350. When the dosing pipe 350 is used to control the entry of drugs, a corresponding dosing valve is provided on the dosing pipe 350.

[0061] Specifically, when the liquid to be treated enters the Rafale tube 330 from the water inlet pipe 340, it gradually accelerates along the Rafale tube 330 and flows toward the opening, and then enters the turbulent aeration component 200 through the connecting pipe 360. Due to the special structure of the Rafale tube 330, the liquid speed increases when passing through the gap between the Rafale tube 330 and the opening, thereby generating a negative pressure area at the gap.

[0062] Because of the negative pressure area generated in the gap, part of the sediment will be re-suspended with the water flow under the effect of negative pressure, and then flow into the circulation box 310 together with the liquid in the circulation pipe 320. When the liquid enters the Rafale tube 330, due to the negative pressure effect, the re-suspended sediment is transported to the turbulent aeration component 200 together with the sediment-carrying liquid entering through the water inlet pipe 340.

[0063] Reference Figure 8 In some embodiments of the present invention, the room temperature crystallization reaction device further includes a precipitate reprocessing component 400, which includes a jet component 410, a water outlet pipe 420, a cyclone sand separator 450 and a sand storage tank 460. The jet component 410 is connected to the chamber 180 and is used to suck the precipitate mixture inside the chamber 180; the cyclone sand separator 450 is connected to the jet component 410 through a connecting pipe 440 and is used to separate the precipitate mixture into solid and liquid; one end of the water outlet pipe 420 is connected to the cyclone sand separator 450 and the other end is connected to the reaction cylinder 110 and is used to transport the separated liquid to the reaction cylinder 110; the sand storage tank 460 is connected to the bottom of the cyclone sand separator 450 and is used to collect the separated solid. A first sand discharge valve 451 is provided between the cyclone sand separator 450 and the sand storage tank 460 , a second sand discharge valve 462 is provided at the bottom of the sand storage tank 460 , and a level meter 461 is provided at the top of the sand storage tank 460 .

[0064] The jet component 410 includes a jet pump 411, a first suction pipe 412, a jet aspirator 415 and a second suction pipe 416. The jet pump 411 is used to provide fluid power; one end of the first suction pipe 412 is connected to the suction port of the jet pump 411, and the other end is connected to the sedimentation area 190. A valve 413 is also provided on the first suction pipe 412; one end of the jet aspirator 415 is connected to the nozzle of the jet pump 411 through the delivery pipe 414, and the other end is connected to the connecting pipe 440; one end of the second suction pipe 416 is connected to the internal bottom end of the reaction tube 110, and the other end is connected to the interior of the jet aspirator 415.

[0065] In the above structure, the jet pump 411 provides the necessary fluid power to drive the operation of the entire jet component 410. One end of the first suction pipe 412 is connected to the suction port of the jet pump 411, and the other end is connected to the sedimentation area 190, and a valve 413 may be provided on the first suction pipe 412 to control the suction process. One end of the jet aspirator 415 is connected to the nozzle of the jet pump 411 through the delivery pipe 414, and the other end is connected to the connecting pipe 440, ensuring that the sediment mixture can be smoothly transmitted to the cyclone sand separator 450. One end of the second suction pipe 416 is connected to the inner bottom end of the reaction barrel 110, and the other end is connected to the inside of the jet aspirator 415, so that the sediment mixture at the bottom of the reaction barrel 110 can also be effectively sucked.

[0066] The sediment mixture is sucked into the cyclone sand separator 450 through the jet component 410, where solid-liquid separation is performed. The cyclone sand separator 450 uses centrifugal force to separate liquid and solid, and the separated liquid is transported back to the reaction cylinder 110 through the outlet pipe 420 to continue to participate in the reaction process. The separated solid falls into the sand storage tank 460, which is used to collect these separated solid sediments. A level meter 461 is provided on the upper part of the sand storage tank 460 to monitor the amount of sediment in the sand storage tank 460 so as to clean it up in time. A first sand discharge valve 451 is provided between the sand storage tank 460 and the cyclone sand separator 450 to control the speed and flow rate of the sediment flowing into the sand storage tank 460; a second sand discharge valve 462 is provided at the bottom of the sand storage tank 460 to discharge the collected sediment.

[0067] Reference Figure 8 In some embodiments of the present invention, the drug adding component 500 includes a drug delivery tube 510, a drug dispensing tube 520 and a plurality of drug outlets 530, wherein the drug delivery tube 510 is embedded in the housing 100, the first end of which is connected to the drug delivery device, and the second end of which extends to the inside of the reaction cylinder 110; the drug dispensing tube 520 is connected to the second end of the drug delivery tube 510 and is located inside the reaction cylinder 110, and the drug dispensing tube 520 is annular; and the plurality of drug outlets 530 are spaced apart on the drug dispensing tube 520. Specifically, a plurality of drug adding components 500 may also be provided, and the plurality of drug adding components 500 are spaced apart along the height direction of the reaction cylinder 110, so that the dosage and uniformity of drug dispensing can be increased.

[0068] In the above structure, after the drug enters the drug delivery tube 510 from the drug infusion device, it flows along the drug delivery tube 510 and finally reaches the drug distribution tube 520. The annular design of the drug distribution tube 520 enables the drug to form a uniform distribution circle in the reaction cylinder. Subsequently, the drug is uniformly released into the liquid in the reaction cylinder through the multiple drug outlets 530 on the drug distribution tube 520. This uniform distribution not only improves the coverage of the drug, but also enhances the effect of the chemical reaction, ensuring that the substances in the liquid to be treated can more fully contact and react with the drug.
