Abstract
Description
Technical Field
[0001] The invention belongs to the field of low-pollution and low-concentration water clarification treatment, and particularly relates to a universal water rapid clarification and anti-scaling system and an application method thereof. Background Art
[0002] In industrial production, such as petrochemical enterprises, steel enterprises, thermal power industry, pesticide and pharmaceutical enterprises, etc., circulating water systems are needed to exchange heat and cool equipment. During the operation of circulating water systems, there are common problems such as heat exchanger scaling, microbial growth, impurity deposition, and water body deterioration. In order to effectively prevent the above problems, the circulating water system generally requires the installation of a bypass filter device in the early stage of construction. In the application of this device, there are problems such as difficulty in backwashing the filter material, compaction of the filter material, large sewage discharge, and high maintenance, which makes the device unable to operate stably for a long time.
[0003] At present, enterprises generally adopt the method of dosing drugs in circulating water to solve the above problems, which also brings about problems such as large discharge volume, adding new pollutants to the water body to form secondary pollution, and continuously increasing treatment costs. In addition, due to the extensive method of adding drugs to the water body, the function of the drugs cannot be fully exerted, resulting in drug waste and excessive pollution. In terms of wastewater dosing treatment, the method of adding drugs and stirring in the dosing barrel is basically adopted. In this way, the drugs and water bodies cannot be fully mixed in the shortest time, which affects the optimal function of the drugs, causing drug loss and excessive addition of drugs, which not only causes economic losses to the company but also causes secondary environmental pollution problems.

[0016] The present invention also provides an application method of a universal rapid clarification and anti-scaling system, the steps of which are as follows:
[0017] S1: The water to be treated first passes through the iron remover through the inlet of the water inlet pipe, and then is input into the pipeline electric flocculation through the input pump; the iron remover uses online cleaning to intercept and remove magnetic substances in the water;
[0018] S2: During operation, the negative electrode of the pipeline housing always maintains high-frequency and low-amplitude fluctuations under the ultrasonic wave of the first transducer, which can prevent the problem of dirt sticking to the wall and positive electrode passivation, and effectively polymerize impurities in the water and promote the mixing of flocculants with the water;
[0019] S3: The electroflocculated material preliminarily mixed with the water body enters the pipeline mixer. An ultrasonic second transducer is set outside the pipeline mixer to perform high-frequency microscopic disturbance on the water body in the pipeline mixer; a static mixing sheet is set inside the pipeline mixer to perform macroscopic disturbance on the water body in the pipeline, and the mass transfer, mixing and polymerization of flocculants and impurities in the water body are further promoted under macroscopic and microscopic disturbances;
[0020] S4: The mixed electro-flocculated substances enter the permanent magnetic cyclone. When the adjustable speed top operation is carried out, the fluid can circulate from the center of the magnetic yoke ring structure under the action of centrifugal force, and enter the U-shaped magnetic yoke along the small holes opened radially around the magnetic yoke, and contact with the NdFeB permanent magnet material embedded in the U-shaped magnetic yoke, so that the fluid passes through the magnetic field, preparing for the subsequent solid-liquid separation;
[0021] S5: The clear liquid and flocculated mixture treated by the permanent magnet cyclone are discharged from the cyclone outlet pipe and enter the water pipe of the pipeline quasi-static separation device, and the treated turbid liquid is discharged from the bottom outlet pipe of the permanent magnet cyclone and enters the sediment separation box; during the flow in the water pipe, the gravity sediment and concentrate generated by flocculation gradually enter the sediment pipe through the sediment inclined pipe connected below the water pipe, and the suspended matter generated in the flocculation enters the suspended matter pipe through the suspended matter inclined pipe connected above; the sediment and suspended matter are in a dynamic separation process through the inclined pipe during the separation process; the clear liquid in the water pipe flows forward steadily to the end, and most of the sediment and suspended matter are separated, and enter the inlet of the pipeline cyclone separator after passing through the water pipe valve on the water pipe; the other two sediment pipes and the suspended matter pipe outlets are collected and transported to the bottom of the sediment separation box after passing through the sediment pipe valve and the suspended matter pipe valve, and discharged outward;
[0022] S6: After the clear liquid passes through the water pipe valve and enters the inlet of the pipe cyclone separator, the fluid generates a rotating flow under the action of two sets of guide vanes. Since the flocculated sediment has a higher specific gravity than the water body, it tends to the outer circle under the action of the cyclone and reaches the tangent fine hole. The pipe diameter becomes smaller and the flocculated sediment is discharged from the tangent fine hole. The clear liquid is discharged from the clear water outlet of the center hole, and the turbid liquid is discharged from the sediment outlet and refluxes to the inlet end of the input pump;
[0023] At the same time, the sedimentation fluid discharged from the bottom flow outlet of the permanent magnet cyclone and the sediment pipe and suspended matter pipe of the pipeline quasi-static separation device enters the sedimentation separation box, and the sediment containing water is quickly separated by the inclined tube settler or the horizontal tube settler. The clear liquid floating on the sedimentation separation box is combined with the clear liquid discharged from the pipeline cyclone separator through the upper clear water outlet pipe, and is transported to the inlet of the input pump as reflux liquid for circulation treatment.
[0024] Compared with the prior art, the present invention has the following beneficial effects:
[0025] 1. The present invention adopts ultrasonic pipeline dosing flocculation technology or electric flocculation technology to avoid electrode polarization and passivation problems, which can not only maintain electrolysis efficiency, but also accelerate the mixing and mass transfer of flocculants and water bodies, thereby improving the flocculation treatment effect.
[0026] 2. The present invention adopts external force driven cyclone magnetization technology to further enhance the flocculation treatment effect.
[0027] 3. The present invention adopts three-layer horizontal tube separation technology to quickly separate flocculated sediments and flocculated suspended matter.
[0028] 4. The present invention adopts pipeline cyclone separation device technology to further separate flocculated sediments to ensure that the output clear liquid quality meets the standards.
[0029] 5. The present invention adopts ultrasonic inclined plate or horizontal plate solid-liquid rapid separation technology to further separate the separated flocculated sediment to minimize the water content of the effluent. If it is used in conjunction with a spiral sludge dewatering machine, the liquid is refluxed and the extrudate is treated as dry garbage or solid waste, closed-loop solid-liquid separation can be achieved.
[0030] 6. The device system of the present invention not only has good water purification and clarification functions, but more importantly has anti-scaling and descaling functions. It can ensure that the clear liquid will not scale in subsequent pipelines and heat exchangers; for equipment that has already scaled, the old scale will gradually fall off.
[0031] 7. The device system of the present invention is mainly composed of pipelines, which occupies a small area and has a large processing capacity per unit volume; each component can be used independently or in combination, and it is easy to implement standardized and modular production and application, and is suitable for various application environments.
[0032] 8. The system of the device of the present invention is easy to expand. Small capacity expansion can be effectively solved by lengthening the length of the pipeline mixer and the horizontal pipe separator pipeline; medium capacity expansion can be effectively solved by increasing the diameter of the pipeline mixer and the horizontal pipe separator pipeline; large capacity expansion can be effectively solved by paralleling the device system.
[0033] 9. The device system of the present invention adopts a four-stage enhanced solid-liquid separation technology, which has fast separation efficiency, good separation effect, small sewage discharge, no secondary pollution problem, strong load impact resistance, and no clogging problem of filtering technology.
[0034] 10. The device system of the present invention can effectively avoid common industrial problems such as scaling, wall sticking, scarring, and blockage during long-term operation, and can completely reach a maintenance-free state. Combined with full-automatic control technology, it can realize a truly unattended processing system.
[0035] 11. The device system of the present invention is a universal purification and separation system, which can be used not only in the field of circulating water purification, but also in the field of wastewater treatment and industrial process. In short, the device system is an efficient pipeline reactor that can effectively replace the traditional dosing box and reactor system.
[0036] In summary, the device system of the present invention improves the flocculation treatment effect by adopting the electric flocculation technology, improves the flocculation treatment effect by combining the mixer, and utilizes the four-stage enhanced solid-liquid separation technology, with fast separation efficiency, good separation effect, small discharge volume, no secondary pollution problem, strong load impact resistance, and no clogging problem of filtering technology. In the long-term operation process, it can effectively avoid common industrial problems such as scaling, wall adhesion, scarring, and clogging. Moreover, each component can be used independently or in combination, and it is easy to implement standardized and modular production and application, which is suitable for various application environments.

DETAILED DESCRIPTION
[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0044] like Figure 1 As shown, a universal rapid clarification and anti-scaling system provided by the present invention, the device system includes a flocculant generating part, a mixing part, an enhanced polymerization part, a solid-liquid separation part, a sediment concentration part and a seed reflux part, namely, a pipeline electroflocculation 1, a pipeline mixer 5, a permanent magnet cyclone 8, a pipeline quasi-static separation device and a pipeline cyclone separation device 18, a sediment separation box 22 and a seed reflux part.
[0045] The flocculant generation part used in the present invention is composed of a pipeline reactor, which can be used to generate flocculants by electric flocculation or by adding drugs.
[0046] The electro-flocculation method produces floccules: the positive electrode of the electro-flocculation is set in a metal pipe, and the material of iron or aluminum is selected according to the characteristics of the treated water body. The negative electrode of the electro-flocculation is common to the pipe, and an ultrasonic transducer is set outside the pipe. The ultrasonic control power supply and the electro-flocculation power supply are set nearby. The characteristics of this device are: first, it can effectively avoid the problems of electrode polarization and electrode passivation and electrolysis efficiency generated during the operation of the electro-flocculation device; second, it can make the flocculent material produced by electrolysis and the impurities in the water body quickly mix, and its mass transfer efficiency is more than 20 times higher than that of ordinary electro-flocculation devices, thereby achieving a better treatment effect. (The pipeline electro-flocculation 1 adopted by the present invention is the electro-flocculation method to produce floccules)
[0047] The method of producing floccules by adding medicine: a dosing port is set at the front end of the metal pipe, a static mixing spoiler is set inside the pipe, an ultrasonic transducer is set outside the pipe, and an ultrasonic control power supply and a dosing device are set nearby. After the liquid medicine enters the pipe, it is quickly mixed within 1 second under the action of ultrasound and spoilers, avoiding the problem of waste caused by hydrolysis of medicines that cannot be mixed quickly. Compared with ordinary dosing devices, the same effect can be achieved by reducing the amount of medicine added by more than 15% when treating the same water body.
[0048] Whether it is the floccules produced by electro-flocculation or by adding drugs, the floccules can be quickly mixed with the water body, and the concentration difference diffusion further promotes the mass transfer effect, which is a microscopic effect; in addition, the water body in the pipeline reactor flows in a piston-like water column, and the water body is updated quickly. From a macroscopic perspective, the mixing of floccules and water is more uniform, and there is no problem of mixing dead corners and repeated mixing due to drug addition. The above two technical results fully ensure the application effect of the device of the present invention.
[0049] The mixing part is set after the flocculant generation part. Its purpose is to further mix the flocculants generated in the front with the water body through mass transfer, and to make preliminary preparations for giving full play to the functions of compression double electric layer, adsorption electric neutralization, adsorption bridge, and precipitation net capture between flocculants and impurities in the water body. This part is composed of a static mixing sheet built into the metal pipe and an ultrasonic transducer set outside the pipe. The mixing effect is more than 15 times higher than that of ordinary cylinder stirring pipe mixers.
[0050] The enhanced polymerization part is arranged after the mixing part. The present invention adopts a permanent magnetic cyclone device. The shell of the device is a cyclone structure, and a rotor permanent magnetic pole that can be driven by an external force is arranged inside.
[0051] The pipeline quasi-static separation device is composed of three layers of horizontal pipes and several inclined pipes, and the angle between the inclined pipes and the horizontal is between 30 degrees and 85 degrees. The water body and the flocculation mixture coming out of the enhanced polymerization device enter the middle horizontal pipe. During the flow process, the gravity sediment and concentrate produced by flocculation gradually enter the lowest horizontal pipe through the lower inclined pipe, and the suspended matter produced in the flocculation enters the uppermost horizontal pipe through the upper inclined pipe. Sediment and suspended matter are in a dynamic separation process through the inclined pipe during the separation process. In order to further improve the separation effect, horizontal inclined plates can be set in the horizontal pipes and the inclined pipes. Ultrasonic transducers are set on the middle horizontal pipe, so that the horizontal and inclined pipes can generate high-frequency compression functions during operation, which can further aggregate impurities in the water body and avoid scaling problems in the pipes.
[0052] The pipeline cyclone separation device is set at the outlet of the middle horizontal pipe. It consists of two parts: one is the cyclone device inside the pipe, which is used to convert the incoming liquid into a cyclone state; the other is the tangent hole on the pipe wall, where the pipe wall is conical, and a sealing barrel is set outside it. The fourth ultrasonic transducer is also set on the sealing barrel to prevent the hole from being blocked and accelerate separation. The clear liquid flows out from the tangent hole and is finally discharged through the clean water outlet pipe on the shell. The turbid liquid flows out from the lower end of the pipe and enters the inlet of the input pump.
[0053] The sediment concentration and seed reflux device, the sediment fluid discharged by the enhanced polymerization and solid-liquid separation device enters the sediment concentration part, and the sediment containing water is quickly separated through the inclined tube or horizontal tube. The floating clear liquid can directly merge with the clear liquid discharged by the pipeline cyclone separation device, or it can be transported to the inlet of the input pump as a reflux liquid for reprocessing. The reflux liquid contains a large amount of seed crystals, which has a good effect on the subsequent purification and scale prevention of water bodies. The seed crystals are the products of flocculation crystallization polymerization, ultrasonic polymerization and magnetization polymerization in the device system. In order to achieve the initial solid-liquid separation, ultrasonic energy is added to the inclined plate or horizontal plate, which can quickly aggregate the particles near the plate wall and accelerate sedimentation; in order to smoothly discharge the sediment on the wall of the hopper at the bottom of the sediment separation box, an ultrasonic transducer is set on the outer wall to prevent the occurrence of wall adhesion when discharging sediment. In addition, in order to further accelerate the sedimentation rate of the sediment, a positively charged electrode plate can be set inside the hopper to adsorb negatively charged flocculated sediment.

[0055] Furthermore, aluminum or iron can be used according to the characteristics of the treated water. The power supply 1.3 must be a safe voltage below 36V, the current is determined by the electrode area, the voltage and current are controllable, and can be either direct current or square wave. The positive electrode 1.1 can be a single-stage, only set inside the negative electrode 1.2, or it can be a multiple-stage, that is, another circle is set outside the negative electrode 1.2, and another layer of negative electrode is added. This can effectively increase the area of the electrode and improve the electro-flocculation treatment capacity.

The water in the pipeline is subjected to high-frequency microscopic disturbance through the second transducer 7, and the water in the pipeline is subjected to macroscopic disturbance through the mixing sheet 6, so that mass transfer, mixing and aggregation of flocculants and impurities in the water are further promoted under macroscopic and microscopic disturbances.
[0058] like Figure 2As shown, the permanent magnet cyclone 8 provided by the present invention includes a cyclone housing 8.1, and a yoke 8.2 is provided in the middle and upper part of the cyclone housing 8.1. The yoke 8.2 includes two upper and lower circular ring structures, and the upper and lower circular ring structures are connected by an inner ring.

From a top view, the yoke 8.2 is a circular ring structure as a whole, and from a horizontal view, the side of the yoke 8.2 is a U-shaped inner concave structure; small holes 8.4 are opened around the radial sides of the yoke 8.2, and the yoke 8.2 can be single-layer or multi-layer, which is determined by the size and processing capacity of the cyclone housing 8.1. The inner ring centers of the upper and lower circular ring structures of the yoke 8.2 are connected to a hollow shaft 8.6 through a bracket, and the hollow shaft 8.6 is connected to an adjustable speed motor 8.5; when the adjustable speed top 8.5 is in operation, the fluid can pass through the magnetic field in the U-shaped yoke 8.2 from the center of the yoke 8.2 under the action of centrifugal force. The device can effectively control the magnetization intensity of water. The following effects can be obtained when the water and flocculants are treated by the device:
[0059] First, it will have a certain impact on the physical and chemical properties of water. After magnetization, the physical and chemical properties of water, such as activity, surface tension, hydrogen bond angle, and solubility, will undergo significant changes.
[0060] Secondly, it is beneficial to weaken the double electric layer of charged particles, reduce the repulsive force of colloidal particles, increase the Zeta potential of particles, promote the rate of floc collision and aggregation to form larger and more stable flocs, and further promote the coagulation and flocculation effects;
[0061] Third, the particle size distribution range of the magnetized flocs becomes narrower, the particle size distribution tends to be more concentrated, and the floc structure becomes more regular.
[0062] Prepare for the subsequent solid-liquid separation.
[0063] The pipeline type quasi-static separation device comprises three layers of horizontal pipes and a plurality of inclined pipes, wherein the three layers of horizontal pipes comprise a water pipe 9 and a sediment pipe 10 and a suspended matter pipe 11 arranged above and below the water pipe 9 and parallel to each other; the water pipe 9 is connected to the inlet of the pipeline cyclone separator 18 through a water pipe valve 17; the plurality of inclined pipes comprise a plurality of sediment inclined pipes 14 and a plurality of suspended matter inclined pipes 12; the sediment pipe 10 and the suspended matter pipe 11 are connected to the water pipe 9 through a plurality of sediment inclined pipes 14 and a plurality of suspended matter inclined pipes 12 respectively, the outlet of the suspended matter pipe 11 is connected to the sediment separation box 22 through a sediment outlet pipe 20 with a sediment pipe valve 21; the outlet of the sediment pipe 10 is connected to the sediment outlet pipe 20 through a suspended matter outlet pipe 16 with a suspended matter induction valve 15. By controlling the opening of the suspended matter pipe valve 15, the water pipe valve 17 and the sediment pipe valve 21, the flow of the clear liquid and the turbid liquid can be reasonably controlled to achieve the best separation effect.
[0064] Further, the distance between adjacent inclined tubes in the plurality of sediment inclined tubes 14 and the plurality of suspended material inclined tubes 12 is defined to be between 200 mm and 500 mm.

The specific values are determined by the processing volume and processing standards, and the pipes are all made of metal.
[0065] In order to further improve the separation effect, a third transducer 13 is arranged on the water pipe 9, so that the three-layer horizontal pipe and inclined pipe can generate a high-frequency compression function during operation, which can further aggregate impurities in the water body and avoid scaling problems in the pipe.

[0068] Furthermore, the sediment separation box 22 is connected to the inlet of the input pump 4 on the water inlet pipe through the upper clear water outlet pipe 22.3 for reflux. The reflux liquid contains a large amount of crystal seeds, which have a good effect on the subsequent purification and scale prevention of the water body.

[0069] Furthermore, an iron remover 3 is provided at the front end of the input pump 4 on the water inlet pipe. The iron remover 3 adopts online cleaning to intercept and remove magnetic substances in the water body.
[0070] The present invention also provides an application method of a universal rapid clarification and anti-scaling system, the steps of which are as follows:
[0071] S1: The water to be treated first passes through the iron remover 3 through the inlet of the water inlet pipe, and then is input into the pipeline electro-flocculation 1 through the input pump 4; wherein, the iron remover 3 uses online cleaning to intercept and remove magnetic substances in the water.

[0073] S3: The electro-flocculated material preliminarily mixed with the water body enters the pipeline mixer 5. Since the ultrasonic second transducer 7 is arranged outside the pipeline mixer 5, the water body in the pipeline mixer 5 is subjected to high-frequency microscopic disturbance. The static mixing sheet 6 is arranged inside the pipeline mixer 5 to perform macroscopic disturbance on the water body in the pipeline, and the mass transfer, mixing and polymerization of flocculants and impurities in the water body are further promoted under the macroscopic and microscopic disturbances.
[0074] S4: The mixed electro-flocculated material enters the permanent magnetic cyclone 8. When the adjustable speed top 8.5 is in operation, the fluid can circulate from the center of the circular structure of the yoke 8.2 under the action of centrifugal force, and enter the U-shaped yoke 8.2 along the small holes 8.4 radially opened on the yoke 8.2, and contact with the NdFeB permanent magnet material 8.3 embedded in the U-shaped yoke 8.2, so that the fluid passes through the magnetic field, preparing for the subsequent solid-liquid separation.
[0075] S5: The clear liquid and flocculated mixture treated by the permanent magnet cyclone 8 are discharged from the cyclone outlet pipe into the water pipe 9 of the pipeline quasi-static separation device, and the treated turbid liquid is discharged from the bottom outlet pipe of the permanent magnet cyclone 8 into the sediment separation box 22; during the flow in the water pipe 9, the gravity sediment and concentrate produced by flocculation gradually enter the sediment pipe 10 through the sediment inclined pipe 14 connected below the water pipe 9, and the suspended matter produced in the flocculation enters the suspended matter pipe 11 through the suspended matter inclined pipe 12 connected above. Sediments and suspended matter are in a dynamic separation process through the inclined pipe during the separation process. The clear liquid in the water pipe 9 flows forward steadily to the end, and most of the sediments and suspended matter are separated, and enter the inlet of the pipeline cyclone separator 18 after passing through the water pipe valve 17 on the water pipe 9. The other two sediment pipes 10 and the suspended matter pipe 11 outlets are collected and transported to the bottom of the sediment separation box 22 after passing through the sediment pipe valve 21 and the suspended matter pipe valve 15.
[0076] S6: After the clear liquid passes through the water pipe valve 17 and enters the inlet of the pipe cyclone separator 18, the fluid generates a rotating flow under the action of the two sets of guide plates 18.1. Since the flocculated sediment has a greater specific gravity than the water body, it tends to the outer circle under the action of the cyclone and reaches the tangent fine hole 18.3. The pipe diameter becomes smaller, and the flocculated sediment is discharged from the tangent fine hole 18.3. The clear liquid is discharged from the clear water outlet 18.4 of the central hole, and the turbid liquid is discharged from the sediment outlet 18.5 and refluxes to the inlet end of the input pump 4.
[0077] At the same time, the sediment fluid discharged from the bottom flow outlet of the permanent magnet cyclone 8 and the sediment pipeline 10 and the suspended matter pipeline 11 of the pipeline quasi-static separation device enters the sediment separation box 22, and the sediment containing water is quickly separated by the inclined tube settler or the horizontal tube settler. The clear liquid floating in the sediment separation box 22 can be directly merged with the clear liquid discharged from the pipeline cyclone separator 18 through the upper clear water outlet pipe 22.3, and can also be transported to the inlet of the input pump 4 as reflux liquid for reprocessing.
[0078] The device system of the present invention adopts the electric flocculation technology to improve the flocculation treatment effect, combines the mixer to improve the flocculation treatment effect, and utilizes the four-stage enhanced solid-liquid separation technology. The separation efficiency is fast, the separation effect is good, the discharge volume is small, there is no secondary pollution problem, the load impact resistance is strong, and there is no clogging problem of the filtering technology. In the long-term operation process, it can effectively avoid common industrial problems such as scaling, wall adhesion, scarring, and clogging. Moreover, each component can be used independently or in combination, and it is easy to implement standardized and modular production and application, which is suitable for various application environments.
