Description
Technical Field
The invention relates to the field of fluid purification, in particular to a fluid purification device and a fluid purification method.
Background
In the prior art, after the aluminum alloy is smelted in a smelting furnace, a refining step is needed, and the refining is realized by adding a refining agent or gas into the aluminum alloy liquid, wherein the refining agent (or gas) reacts with the liquid. The traditional feeding mode of the refining agent (or gas) is that after the aluminum alloy is smelted in a smelting furnace, the refining agent or gas is added into the smelting furnace, so that the refining agent (or gas) is mixed with liquid, and the aluminum alloy liquid is discharged into a heat preservation furnace after mixing. In this way, the refining agent (or gas) gradually reacts to generate slag after contacting with the aluminum alloy, so that slag beating operation is required in the smelting furnace and the holding furnace, and liquid purification is realized.
In order to make the aluminum alloy liquid and the refining agent (or gas) in the smelting furnace fully contact and react, after the refining agent or gas is added into the smelting furnace, mechanical stirring is performed, and stirring is performed by mechanical equipment, so that the aluminum alloy melt and the refining agent (or gas) are fully contacted and mixed as much as possible.
The purification mode has the following defects: 1. the smelting furnace or the heat preservation furnace is large in internal volume, slag is distributed on the surface of liquid and is dispersed, the volume of the slag-beating tool is much smaller than that of the smelting furnace, the slag-beating tool is not easy to salvage slag in the slag salvaging process, and meanwhile the problem that slag at four corners of the furnace is not salvaged cleanly exists is solved, so that the slag-removing quality and efficiency are affected. Meanwhile, when the refining agent or gas is added into the smelting furnace, the mechanical stirring range is limited, and dead angles exist for stirring, so that the added refining agent or gas is unevenly distributed and is not fully reacted with the liquid, and the quality and efficiency of liquid purification are affected.
2. In order to enable the mechanical stirring equipment to have a larger stirring range as far as possible, the furnace door of the smelting furnace is opened to a larger extent or the furnace door opening of the smelting furnace is arranged to be larger, so that the mechanical stirring equipment can move transversely or vertically, the stirring range is improved, but the problems of larger heat loss and energy waste are caused due to the fact that the furnace door is arranged to be larger or the furnace door is opened to a larger extent.
3. At present, the current industry can only wait for the charging in the smelting furnace to be completed, and after the aluminum alloy melt in the smelting furnace is fully mixed with the refining agent (or gas), the aluminum alloy melt is transferred into the heat preservation furnace, so that the whole process takes more time, and the processing production efficiency is required to be improved.
In summary, the existing aluminum alloy melt purification has the problems of uneven mixing and stirring of refining agent and/or gas and liquid in a smelting furnace, heat loss, energy waste, long purification time, low efficiency and the like.
Disclosure of Invention
The present invention is directed to a fluid purification apparatus and method to improve the efficiency and quality of fluid purification.
In order to achieve the above purpose, the invention adopts the following technical scheme: the fluid purification device comprises a runner well, a liquid inlet channel and a liquid outlet channel connected to the side wall of the runner well, wherein a vertical separation part is fixedly arranged in the runner well, the separation part transversely divides the inside of the runner well into a vortex area and a stable area which are mutually communicated, and a slag notch communicated with the stable area is arranged on the runner well; the liquid inlet channel is connected to the side wall of the vortex area, and the liquid inlet direction of the liquid inlet channel points to the inner wall of the vortex area.
The principle and the advantages of the scheme are as follows: according to the scheme, fluid enters the runner well from the liquid inlet channel, flows out of the runner well through the liquid outlet channel, initially, the liquid level in the runner well is gradually increased, when the liquid level reaches a certain height, the liquid level is located between the top and the bottom of the separation part, and then the liquid level in the runner well is kept stable by controlling the speed of the fluid entering the runner well and the speed of the fluid flowing out of the runner well.
After the liquid level of the fluid is stable in the runner well, the fluid enters the runner well from the liquid inlet channel, the surface of the fluid forms a vortex in the vortex area under the action of fluid flow impact, and at the moment, after the agent and/or gas capable of reacting with the fluid are added into the vortex area of the runner well, the agent and/or gas are stirred in the horizontal direction under the action of the vortex, and meanwhile, the agent and/or gas can move downwards under the action of the vortex, so that the agent and/or gas can be fully mixed and reacted with the fluid.
Because swirl district and steady district are intercommunication each other, consequently the little sediment that the reaction produced after adding agent and/or gas and the impurity in the fluid contact also can diffuse and float and enter into the steady district, the steady district separates with the swirl district under the effect of division, the steady district can not directly receive the impact of the fluid that gets into from the inlet channel like this, the liquid in the steady district compares the liquid in swirling district comparatively stably, the sediment in the runner well gathers in the steady district easily, then carry out the sediment processing of beating through the sediment mouth direct or indirect with the sediment on the liquid surface in the steady district to the clearance of sediment has been realized. Meanwhile, the separation part also has a certain blocking effect on slag in the stable region, and the slag in the stable region is prevented from diffusing to the vortex region.
The technical scheme has the following beneficial effects:
1. according to the scheme, online feeding is performed in the runner well in the liquid flowing process, feeding in a previous container is not needed, in the feeding process, the vortex area utilizes vortex generated by fluid flowing, so that the agent and/or gas added into the vortex area is dispersed under the action of the vortex, the added agent and/or gas can be fully stirred, mixed and reacted with the liquid, and compared with the mode of mechanical stirring in the prior art, the problem of stirring and mixing dead angles is avoided, and the efficiency and quality of fluid purification are improved.
2. After feeding, a small amount of slag can be generated in the liquid, the liquid level in the stable region is more stable than the liquid level in the swirling region, and the slag is easy to gather and float in the stable region, so that the gathering degree of the slag is improved, the slag in a runner well is convenient to salvage, the slag is not required to be formed after the liquid is completely discharged into a next device, the slag forming efficiency and quality are improved, and the fluid purifying efficiency and quality are improved.
3. According to the scheme, fluid continuously enters the runner well from the liquid inlet channel, and the fluid is discharged from the runner well through the liquid outlet channel, so that liquid is fed in the flowing process, the liquid does not need to be discharged after feeding and mixing in the last container before entering the runner well, the feeding and mixing are carried out in the last container, the feeding and mixing of the fluid while discharging from the last container are realized, namely, the online feeding of the liquid is realized, the whole feeding process does not occupy the liquid transferring time, and meanwhile, the feeding time in the last container is not occupied, so that the liquid purifying time is greatly saved, and the overall efficiency of liquid treatment is improved.
4. The slag beating process is to beat slag from the liquid in the runner well, compared with the slag beating process performed in the previous container before the fluid enters the runner well, the volume of the runner well is far smaller than that of the previous container, compared with the stirring and slag beating process performed in the previous container with larger volume, the stirring and slag beating range is reduced, stirring and slag beating efficiency is higher, and the slag beating effect is better.
5. If the fluid needs high-temperature heat preservation, the scheme does not need to carry out feeding and slag beating operations in the previous container, so that a larger opening is not needed to be arranged in the previous container, and heat loss and energy waste in the previous container can be reduced.
In summary, the scheme solves the problems of uneven mixing and stirring of refining agent and/or gas and the liquid in the previous container, heat loss, energy waste, long purification time, low efficiency and the like, and simultaneously has a plurality of technical effects and remarkable effect. Even if a scheme for solving the problems exists in the prior art, a plurality of problems cannot be solved at the same time, and a plurality of effects cannot be achieved.
Preferably, as an improvement, the connection part of the liquid inlet channel and the runner well is positioned at the end part of the side wall of the vortex area, the connection part of the liquid outlet channel and the runner well is positioned at the other end part of the side wall of the vortex area, and the separation part comprises a slag blocking part and a flow guiding part;

Therefore, through the scheme, when the liquid inlet channel is close to the side wall of the stable region and the flow guide part are connected, and liquid flows from the liquid inlet channel into the runner well, the liquid flows towards the direction of the vortex region under the action of the flow guide part, the flow guide part plays a role in guiding the flow direction of the liquid, the liquid is reduced to flow towards the direction of the stable region, the impact on the liquid in the stable region is reduced, and meanwhile, the liquid flowing into the vortex region forms vortex more easily under the guiding action of the flow guide part. The slag blocking part is used for blocking slag on the surface of the liquid in the stable region, controlling the floating slag on the surface of the liquid in the range of the stable region and reducing the flow of the slag to the direction of the vortex region.

The direction of agitation of the rotor may be opposite to the direction of rotation of the fluid vortex, thereby increasing the cutting of the fluid, facilitating turbulence of the liquid and further enabling more thorough mixing of the agent and/or gas with the fluid.
Preferably, as a modification, an electromagnetic sensor for generating a magnetic field is arranged on the outer side of the runner well, and the magnetic field acts on the fluid.
By electrifying the electromagnetic inductor, the electromagnetic inductor can generate a magnetic field, and the liquid in the runner well can continuously roll up and down in the runner well under the action of the magnetic field, so that the phenomenon of turbulent flow is enhanced, and the liquid and the agent and/or gas added into the runner well are fully mixed.

Example 1
As shown in fig. 1-2, the present embodiment relates to a fluid purifying apparatus for purifying a fluid, and of course, the kind of the fluid is not limited, for example, purification of waste water and purification of metal liquid, and the apparatus of the present embodiment specifically describes an aluminum alloy melt as a purifying object.
The utility model provides a fluid purification device, combines the fig. 1 and the fig. 2 to show, includes runner well 1, is connected with inlet channel 3 and drain 4 on runner well 1 lateral wall, and inlet channel 3 and drain 4 all transversely set up, and runner well 1 vertical setting, the top of inlet channel 3 and the top of drain 4 all are in open state, and of course the top of inlet channel 3 and the top of drain 4 also can be in confined state. In this embodiment, the liquid inlet channel 3 and the liquid outlet channel 4 are both close to the top of the runner well 1, and the liquid inlet channel 3 and the liquid outlet channel 4 may be at the same height, or the liquid inlet channel 3 may be between 5 mm and 1 cm higher than the liquid outlet channel 4.
The inside of runner well 1 is fixed and is equipped with vertical partition portion, and the partition portion is the platelike structure specifically, and the top of feed liquor way 3 and the top of drain way 4 are all less than the top of partition portion, and the bottom of feed liquor way 3 and the bottom of drain way 4 are all higher than the bottom of partition portion. The partition portion in this embodiment includes a first partition portion 6 and a second partition portion 7, the first partition portion 6 and the second partition portion 7 are welded or bolted to the inner wall of the flow path well 1, the first partition portion 6 and the second partition portion 7 are symmetrically disposed in this embodiment, and the connection line of the first partition portion 6 and the second partition portion 7 laterally divides the interior of the flow path well 1 into mutually communicating swirling areas 2 and leveling areas 5, because the bottom of the partition portion does not abut against the bottom of the flow path well 1, the swirling areas 2 and leveling areas 5 are in a communicating state.
A slag hole which is opposite to and communicated with the stable region 5 is arranged on the runner well 1, and the slag hole can be arranged at the top of the runner well 1 or the position of the side wall of the runner well 1 close to the top end; the liquid inlet channel 3 is connected to the side wall of the vortex area 2, and the liquid inlet direction of the liquid inlet channel 3 points to the inner wall of the vortex area 2. Thus, through this embodiment, the aluminum alloy liquid melted in the melting furnace (the previous container) enters the runner well 1 from the liquid inlet channel 3, the runner well 1 is empty initially, the liquid enters the runner well 1 downward under the action of gravity after entering from the liquid inlet channel 3, the liquid is not discharged at this time, the liquid level gradually rises, and after the liquid level of the liquid reaches the height of the liquid outlet channel 4, the liquid in the runner well 1 flows out from the runner well 1 through the liquid outlet channel 4. Then the flow rate of the liquid entering the runner well 1 from the liquid inlet channel 3 and the flow rate of the liquid exiting the runner well 1 are controlled (flow rate control method, for example, the positions of the smelting furnace, the runner well 1 and the liquid outlet channel 4 are respectively provided with a gate, and the opening degree of the gate is controlled to control the flow rate), so that the flow rates of the two are equal, and the liquid level in the runner well 1 is kept stable. At this time, the smooth liquid surface of the runner well 1 is located between the top and bottom of the partition, and the liquid surface does not go over the top of the liquid inlet channel 3 and the top of the liquid outlet channel 4.
After the liquid level of the fluid is stable in the runner well 1, the fluid continuously enters the runner well 1 from the liquid inlet channel 3, and the surface of the fluid forms a vortex in the vortex area 2 under the action of fluid flow impact, and the vortex has certain circumferential stirring on the fluid and stirring for enabling the fluid to move downwards. At this time, after the granular refining agent and/or gas (argon or chlorine) is added into the vortex area 2 of the runner well 1, the refining agent and/or gas is stirred in the horizontal direction under the action of the vortex, and meanwhile, the refining agent and/or gas can move downwards under the action of the vortex, so that the refining agent and/or gas can be fully mixed and reacted with fluid.
Of course, the refining agent and/or gas can be added to the swirl zone 2 of the runner well 1 manually, or by arranging a graphite rotor shaft 9, the interior of the rotor shaft 9 is hollow, the bottom of the rotor shaft 9 is provided with a rotor turntable 8, the part of the rotor shaft 9, which is positioned outside the runner well 1, is provided with an inlet, the part of the rotor shaft 9, which is positioned inside the runner well 1, is provided with an outlet, so that the refining agent and/or gas is added into the rotor shaft 9 through the inlet, and flows out through the outlet of the rotor shaft 9, thereby realizing the addition of the refining agent and/or gas into the runner well 1. Then the rotor shaft 9 is driven to rotate by the motor outside the device, and the rotor shaft 9 drives the rotor turntable 8 to stir the liquid, so that the refining agent and/or gas are mixed with the fluid and react more fully. Of course, the stirring direction of the rotor shaft 9 may be set according to the actual situation, for example, the same or opposite to the rotation direction of the fluid vortex, and when opposite, the cutting of the fluid by the rotor disc 8 can be increased, which is beneficial to the turbulence of the liquid and further to the more sufficient mixing of the refining agent and/or gas with the fluid.
In this embodiment, the gas added to the rotor shaft 9 is a gas with a certain pressure (for example, the gas is pressed into the rotor shaft 9 by a pump), so that the gas can better enter the liquid, and the gas and the refining agent powder can drive the refining agent powder to be ejected from the outlet of the rotor shaft 9 when the gas and the refining agent powder are added together.
The added refining agent can react with impurities in the liquid to form slag, and the chlorine can react with alkali metals such as sodium, potassium, calcium and the like in the aluminum alloy melt. By introducing argon gas into the runner well 1, hydrogen gas in the aluminum alloy melt in the runner well 1 can be extruded.
Because the swirling zone 2 and the stabilizing zone 5 are mutually communicated, a part of slag generated in the runner well 1 can be diffused and float into the stabilizing zone 5, the stabilizing zone 5 is separated from the swirling zone 2 under the action of the first separating part 6 and the second separating part 7, so that liquid in the stabilizing zone 5 can not be directly impacted by fluid entering from the liquid inlet channel 3, the slag is more stable than the liquid in the swirling zone 2, the slag is easy to gather in the stabilizing zone 5, then the slag floating on the surface of the liquid is directly subjected to slag tapping treatment through a slag hole (slag tapping tool is manually controlled or a slag tapping machine is used for driving a slag tapping plate to enter the stabilizing zone 5 through a slag hole to tap slag), or the slag on the surface of the liquid in the stabilizing zone 5 is indirectly subjected to slag tapping treatment (the slag in the stabilizing zone 5 is introduced into the slag tapping pool 10 through the slag hole, and then the slag tapping tool is manually controlled or the slag tapping plate is used for tapping the slag in the slag tapping pool 10).
In this embodiment, the liquid flows out from the liquid outlet 4 and then flows to the holding furnace (next device), and after the liquid is kept still in the holding furnace, the slag is further removed from most of the slag in the liquid. Therefore, the feeding and slag-beating operation in the smelting furnace is not needed, the traditional purification mode in the smelting furnace is changed, the feeding and certain slag-beating operation can be realized in the process of transferring the liquid in the smelting aluminum to the heat preservation furnace, the liquid in the smelting furnace is not needed to be transferred after being fully mixed with the refining agent or the gas, the transfer time of the fluid cannot be occupied in the feeding process, the fluid purification and transfer time is greatly saved, and the overall production and manufacturing efficiency is improved.
In the present embodiment, the shape of the flow path well 1 in the plan view is circular, but in other embodiments, the shape of the flow path well 1 in the plan view may be square, polygonal, or the like. The top view shape of the runner well 1 is any shape, and the side wall of the vortex area 2 protrudes towards the outer side direction of the runner well 1, so that the liquid is favorable to forming a vortex after flowing out from the liquid inlet channel 3, and in the embodiment, the side wall of the vortex area 2 is in an arc shape, so that the formation of a fluid vortex is more favorable. In connection with fig. 2, for better swirl formation, when the swirl zone of the runner well is arc-shaped, it is preferable that the liquid inlet channel 3 is directed obliquely in the horizontal direction to the runner well 1, i.e. the liquid inlet direction of the liquid inlet channel 3 cannot be perpendicular to the tangent line of the runner well 1, because after the liquid inlet direction of the liquid inlet channel 3 is perpendicular to the tangent line of the runner well 1, the liquid may not flow along the inner wall of the swirl zone 2 of the runner well 1 (for example, when the liquid inlet direction of the liquid inlet channel 3 is opposite to the plateau 5). The liquid inlet channel 3 is obliquely directed to the runner well 1 in the horizontal direction, and after the liquid enters the runner well 1, the liquid flows along the inner wall of the swirling area 2 of the runner well 1, and the inner wall of the runner well 1 plays an early role in guiding the flow of the liquid, so that the formation of vortexes is facilitated. It is further preferred that the acute angle between the liquid inlet channel 3 and the tangent of the runner well 1 in the horizontal direction is 0-45 degrees.
The space of the stable region 5 is smaller than that of the vortex region 2 in the embodiment, so that the space of the stable region 5 is smaller, the slag aggregation degree is larger, and the quality and efficiency of slag beating are improved conveniently. Meanwhile, the space of the stable region 5 is small, the slag notch is not too large, and heat loss and energy waste can be reduced.
In addition, in other embodiments, as shown in fig. 6, the first partition portion 6 is bent, the first partition portion 6 includes a guide portion 62 and a slag blocking portion 61, the slag blocking portion 61 and the guide portion 62 are integrally or welded and fixed, as shown in fig. 2, a portion where the liquid inlet channel 3 and the runner well 1 are connected is located at a side wall end portion of the swirling zone 2, a side wall end portion of the liquid inlet channel 3 close to the plateau 5 is welded to an end portion of the guide portion 62 of the first partition portion 6, and the slag blocking portion 61 of the first partition portion 6 is located at a side of the guide portion 62 close to the plateau 5, that is, the slag blocking portion 61 is bent in a direction away from the swirling zone 2. Thus, when the liquid flows into the runner well 1 from the liquid inlet channel 3, the liquid flows towards the vortex region 2 under the action of the flow guide part 62 of the first separation part 6, the flow guide part 62 plays a role in guiding the flow direction of the liquid, the liquid is prevented from flowing towards the stable region 5, the impact on the liquid in the stable region 5 is reduced, and meanwhile, the liquid flowing into the vortex region 2 is easier to form vortex under the guiding action of the flow guide part 62. The slag blocking part 61 of the first separation part 6 is used for blocking slag on the liquid surface of the stable region 5, controlling the floating slag on the liquid surface within the range of the stable region 5 and reducing the floating slag from flowing towards the vortex region 2.
As shown in fig. 2, the connection portion of the liquid outlet channel 4 and the flow channel well 1 is located at the other end portion of the side wall of the swirling zone 2, and the second partition portion 7 and the first partition portion 6 are identical in structure and symmetrical with respect to a vertical center line (not shown) in fig. 2. Similarly, the end of the side wall of the liquid outlet channel 4 close to the stable region 5 is welded with the end of the flow guiding part 62 of the second partition part 7, and the slag blocking part 61 of the second partition part 7 is positioned on one side of the flow guiding part 62 of the second partition part 7 close to the stable region 5. Thus, the first and second partition portions 6 and 7 have a gap therebetween, so that the rotation of the rotor is not affected, and the slag can be blocked by the first and second partition portions 6 and 61 and the slag blocking portion 61 of the second partition portion 7. In addition, the diversion part 62 of the first separation part 6 is connected to the end part of the liquid inlet channel 3 near the side wall of the stable region 5, the diversion part 62 of the second separation part 7 is connected to the end part of the liquid outlet channel 4 near the side wall of the stable region 5, both the end part of the diversion part 62 of the first separation part 6 and the end part of the diversion part 62 of the second separation part 7 are welded with the slag forming pond 10 positioned outside the runner well 1, so that the first separation part 6 and the second separation part 7 can be considered as part of the slag forming pond 10, slag positioned in the stable region 5 can enter the slag forming pond 10 through a slag hole, and the slag forming can be performed on the liquid surface of the slag forming pond 10 at the moment, and the structural design is ingenious.
Of course, in other embodiments, the partition portion may be in the shape of fig. 7, and the partition portion is an integral body, that is, includes the slag blocking portion 61 and the flow guiding portions 62 located at two ends of the slag blocking portion 61, the flow guiding portion 62 on the right side is welded or bolted to the end portion of the liquid inlet channel 3 near the side wall of the stable region 5, and the flow guiding portion 62 on the left side is welded or bolted to the end portion of the liquid outlet channel 4 near the side wall of the stable region 5, so that the functions of blocking slag in the stable region 5 and guiding liquid can be achieved. Of course, the rotor shaft 9 should be avoided when the partition is provided. The partition may also be provided in different shapes depending on the actual situation.
Of course, the bottom of the runner well 1 can be provided with a drain pipe, and a valve is arranged on the drain pipe, so that the valve is in a closed state when the runner well 1 is used normally, and the liquid can maintain the normal liquid level in the runner well 1. When the runner well 1 needs to be overhauled to thoroughly empty the liquid in the runner well 1, the liquid can be discharged from the liquid discharge pipe by opening the valve.
As shown in fig. 3 and 4, in other embodiments, the runner well 1 includes an inner ring 17, a heat insulating layer 14, and an outer ring 13, the outer ring 13 being sleeved outside the inner ring 17, the heat insulating layer 14 being located between the inner ring 17 and the outer ring 13. The outer ring 13 in this embodiment is a stainless steel outer ring 13, the inner ring 17 is formed by pouring stainless steel or casting materials, the heat insulation layer 14 between the outer ring 13 and the side wall of the runner well 1 is made of heat insulation materials (such as aluminum silicate or nano heat insulation materials), and the heat insulation layer 14 is arranged to insulate the aluminum alloy melt in the runner well 1, so that the temperature of the aluminum alloy melt is not lower than the melting point. Of course, a heating rod may be provided in the runner well 1 to heat the aluminum alloy melt so that the temperature of the aluminum alloy melt is not lower than the melting point.
The thickness of the inner ring 17, the outer ring 13 and the heat insulation layer 14 in this embodiment may be set according to practical situations, for example, when the inner ring 17 is made of castable, the thickness of the outer ring 13 may be 5-8mm, the thickness of the heat insulation layer 14 may be 20-30mm, and the thickness of the inner ring 17 may be 70-90mm; when the inner ring 17 is made of stainless steel, the thickness of the inner ring 17 can be reduced and the thickness of the heat insulating layer 14 can be increased as compared with when the inner ring 17 is made of casting material.

By energizing the electromagnetic inductor, the electromagnetic inductor can generate a plurality of magnetic fields (traveling wave magnetic fields) in orange shapes (similar to the shape of the earth magnetic field), and the magnetic fields have certain deslagging effect: the great difference of conductivity and magnetic permeability between the metal and nonmetal particles in the liquid can separate them under a strong magnetic field, so that nonmetallic fine inclusions in the liquid can be removed rapidly.
Meanwhile, the liquid in the runner well 1 can continuously roll up and down in the runner well 1 under the action of a magnetic field, and the vertical stirring of the liquid is realized under the action of original liquid stirring, so that the phenomenon of turbulent flow of the liquid is enhanced, and the liquid is favorable for fully reacting with the refining agent and/or gas added into the runner well 1.
The electromagnetic inductor in the embodiment consists of a layered iron core and a coil winding, wherein the coil is in dry insulation and fixed around the iron core, the coil is fed with three-phase low-frequency alternating current (0.5-5 HZ), the electromagnetic inductor is controlled by a frequency converter, and the magnitude and the direction of magnetic field force can be changed by changing the current, the frequency and the phase sequence of a frequency conversion power supply, so that the magnitude and the direction of liquid stirring force are changed.
Whether the electromagnetic inductors are one group or two groups, the sum of the vertical heights of the electromagnetic inductors is not lower than 800mm, for example, when one group of electromagnetic inductors is used, the height of a single electromagnetic inductor is not lower than 800mm, and when two groups of electromagnetic inductors are used, the sum of the heights of the two electromagnetic inductors is not lower than 800mm. During electromagnetic stirring, the current is in the range of 1-1000A, preferably 300-800A in this embodiment. Since the flow passage well 1 is circular, the electromagnetic sensor in this embodiment is arc-shaped, and the inner diameter of the electromagnetic sensor may be set to 0.5-2m and the outer diameter of the electromagnetic sensor may be set to 0.7-2.2m according to the diameter of the flow passage well 1. The coil is formed by winding a copper wire or a hollow copper tube, if the hollow copper tube is adopted, cooling water can be introduced into the copper tube, the number of turns of each group of coils is 20-200, preferably 100, and the number of turns of the coils can be set in other ways according to practical situations. The number of the coil windings can be 4-8, and the number of the coil windings can be set in other ways according to actual conditions.
The electromagnetic inductor in this embodiment includes a first electromagnetic inductor 11 and a second electromagnetic inductor 12, where the first electromagnetic inductor 11 and the second electromagnetic inductor 12 are both arc-shaped, the volume of the first electromagnetic inductor 11 is larger than that of the second electromagnetic inductor 12, the first electromagnetic inductor 11 is located on the outer side of the side where the swirl zone 2 is provided in the runner well 1, specifically located on the outer side of the outer ring 13, and the second electromagnetic inductor 12 is located on the outer side of the side where the plateau zone 5 is provided in the runner well 1, specifically located on the outer side of the outer ring 13. Since the volume of the first electromagnetic inductor 11 is larger than that of the second electromagnetic inductor 12, the first electromagnetic inductor 11 is arranged below the second electromagnetic inductor 12, so that the whole device is stable.
Therefore, the first electromagnetic inductor 11 and the second electromagnetic inductor 12 are respectively connected with a frequency converter, and the magnitude and direction of the magnetic field force of the first electromagnetic inductor 11 and the second electromagnetic inductor 12 can be changed by changing the current, the frequency and the phase sequence of the frequency conversion power supply, so that the magnitude and the direction of the liquid stirring force (in terms of the direction, the force directions of the two groups of electromagnetic inductors for stirring the liquid are set according to the actual conditions, such as the vertical same direction or vertical opposite direction, so as to control the turbulence. The first electromagnetic sensor 11 in this embodiment is far from the plateau 5, the second electromagnetic sensor 12 is small in volume, and the generated magnetic field acting force is small, so that the second electromagnetic sensor 12 near to the plateau 5 has small electromagnetic action on the liquid in the plateau 5, and the liquid in the plateau 5 can be kept relatively stable. The first electromagnetic inductor 11 has larger volume and larger magnetic field acting force, so that the first electromagnetic inductor 11 has large electromagnetic action on the liquid in the vortex area 2, the liquid in the vortex area 2 can be fully stirred, and the first electromagnetic inductor 11 is far away from the stable area 5 and cannot have large electromagnetic action on the stable area 5.
The magnetic field that this embodiment mainly utilized electromagnetic induction ware to the effort of liquid, realized stirring of liquid, compare mechanical stirring, can not appear stirring the problem at dead angle, improved the efficiency and the effect of purifying. The above embodiment discloses two sets of electromagnetic inductors, and the number and arrangement of the electromagnetic inductors can be set according to actual situations.
