Description

Technical Field

[0001] The invention relates to the technical field of wastewater ion exchange equipment, and in particular to an industrial wastewater discharge treatment device and method. Background Art

[0002] In the treatment of industrial wastewater discharge, the basic principle of the wastewater ion exchange treatment method is to exchange the exchange ions in the ion exchanger with the ions in the wastewater, use resin particles as carriers, and regularly replenish the resin particles with ion exchange liquid to remove harmful ions in the wastewater. The power of the exchange process mainly comes from the concentration difference between ions and the affinity of the functional groups on the exchanger to ions. There are many types of wastewater discharge treatment devices. Among them, the hybrid ion exchanger is characterized by its positive and negative ion exchange resins can simultaneously perform positive and negative ion exchange work in the tank body, and has the advantages of high efficiency. However, when the positive and negative ions of the current industrial wastewater discharge treatment device are replenished, they are mainly separated by the density difference between the positive and negative ion resin particles by standing still. The subsequent replenishment work has poor accuracy, and it is difficult to ensure that the positive and negative resin particles are accurately distinguished. It is not convenient to perform layered sealed replenishment, and it is also not convenient to automatically switch the resin ions that have reached their service life. It relies on manual observation, which affects the wastewater treatment effect. At the same time, manual backflow flushing and other operations are cumbersome and inefficient, and it is not convenient to replenish ion exchange liquid without stopping the machine.

[0041] In the embodiment of the present disclosure, the water collecting part 1 also includes: a liquid inlet cover plate 102 and a liquid discharge isolation cylinder 103, the liquid inlet cover plate 102 is installed on the top of the water collecting tank 101 by bolts; the liquid inlet cover plate 102 is provided with an inlet pipe for introducing waste water; the liquid discharge isolation cylinder 103 is fixedly installed inside the water collecting tank 101; the liquid discharge isolation cylinder 103 is externally connected to a drainage hose; the switching part 2 includes: a switching motor 201, a switching block 202 and a rotating liquid replenishing hole 2021, the switching motor 201 is fixedly installed on the water collecting tank 101; the output shaft of the switching motor 201 passes through the water collecting tank 101; the switching block 202 is fixedly installed on the output shaft of the switching motor 201; the switching block 202 is provided with three threaded holes; the switching block 202 is rotatably sleeved inside the water collecting tank 101; the switching block 202 is provided with three rows of rotating liquid replenishing holes 2 021; three rows of rotating fluid replenishment holes 2021 are respectively aligned with a row of fixed fluid replenishment holes 1012; the top of the switching block 202 is attached to the drainage isolation cylinder 103; the switching part 2 can be used to cooperate with the water collecting part 1 to realize the rotation and replacement of the ion exchange part 3, which can increase the water treatment flexibility of the present structure, and avoid the single ion exchange part 3 being unable to continue to treat wastewater after the capacity is reduced, resulting in the suspension of wastewater treatment. The present structure is simple to control. After the liquid inlet cover plate 102 is filled with water, the liquid is discharged from the drainage isolation cylinder 103. The wastewater after ion exchange can be fully utilized to clean the ion exchange part 3 with reduced capacity, which is convenient for subsequent fluid replenishment. The present structure can use the three ion exchange parts 3 for recycling to ensure the use cycle of the present structure, and can be electrically controlled to switch to ensure the continuity of wastewater treatment and reduce industrial wastewater pollution.

[0042] In the disclosed embodiment, the ion exchange section 3 includes: an exchange mounting cylinder 301, a liquid through port 3011 and a fixed isolation net 302, the exchange mounting cylinder 301 is sleeved inside the switching block 202; the bottom of the exchange mounting cylinder 301 is threadedly connected to the threaded hole on the switching block 202; ten rows of liquid through ports 3011 are provided on the exchange mounting cylinder 301, and the heights of the ten rows of liquid through ports 3011 correspond to the rotating liquid replenishing holes 2021 respectively; a row of fixed isolation nets 302 are fixedly installed inside the exchange mounting cylinder 301, and a row of fixed isolation nets 302 are respectively located at the intervals of a row of fixed liquid replenishing holes 1012; positive and negative ion exchange resins are filled at intervals between a row of fixed isolation nets 302, and the ion exchange section 3 used can utilize the intervals formed between a row of fixed isolation nets 302 to isolate positive and negative ion exchange resins and avoid mixing of ion exchange resins.

At the same time, the exchange mounting cylinder 301 used is flexible to disassemble, which ensures practicality. After the bolts between the liquid inlet cover plate 102 and the water collecting tank 101 are removed, the exchange mounting cylinder 301 at the drainage isolation cylinder 103 can be rotated and disassembled, and the water inlet pipe on the liquid inlet cover plate 102 is connected to the wastewater pump for water inlet. After the wastewater is exchanged with the positive and negative ion exchange resins in the two exchange mounting cylinders 301 below, the treated industrial wastewater is discharged from the exchange mounting cylinder 301 located at the drainage isolation cylinder 103 under the action of water pressure, and can be discharged through the drainage hose on the side of the drainage isolation cylinder 103. In the process, the positive and negative ion exchange resins inside the exchange mounting cylinder 301 located at the drainage isolation cylinder 103 will be washed with water, which is convenient for the subsequent replenishment of ion exchange liquid.

[0043] In the disclosed embodiment, the positive and negative ion rehydration component 4 includes: a rehydration cover 401 and a rehydration tube 402. The rehydration cover 401 is provided with two rows, and the two rehydration covers 401 are respectively fixedly installed on the side of the water collecting tank 101; the two rows of rehydration covers 401 are respectively covered and buckled on the outside of a row of fixed rehydration holes 1012; the two rows of rehydration covers 401 are arranged crosswise at intervals; the two rows of rehydration covers 401 are respectively fixedly installed with rehydration tubes 402, and the two rows of rehydration tubes 402 are respectively provided with valves; the two rehydration tubes 402 are respectively connected to positive and negative ion rehydration pumps; the rehydration isolation component 5 includes: a shunt tube 501, a sealing plate 502, a sliding block 5021, a tension spring 503, a shunt chamber 504 and a magnetic iron ring 505, the shunt The pipe 501 is slidably sleeved on a row of fixed isolation nets 302; a row of sealing plates 502 are fixedly installed on the shunt pipe 501, and the row of sealing plates 502 are respectively mesh structures; the mesh holes on the row of sealing plates 502 are respectively staggered with the mesh holes on the row of fixed isolation nets 302; a circle of sliding blocks 5021 are respectively fixedly installed on the row of sealing plates 502, and the circle of sliding blocks 5021 are respectively slidably installed on the inner side of the exchange installation cylinder 301; a tension spring 503 is sleeved on the shunt pipe 501; the end of the tension spring 503 is connected to the bottom of the fixed isolation net 302 at the bottom; the other end of the tension spring 503 is connected to the shunt pipe 501; a shunt cavity 504 is provided at the bottom of the shunt pipe 501, and the shunt cavity 504 is provided at the bottom of the shunt pipe 501. The inner diameter of the flow cavity 504 is larger than the inner diameter of the shunt tube 501; the magnetic iron ring 505 is fixedly installed at the bottom of the shunt tube 501; the positive and negative ion exchange resins are located between the bottom of the fixed isolation net 302 and the top of the sealing plate 502. The use of the positive and negative ion refilling parts 4 can facilitate the staff to refill the positive ion exchange resin and the negative ion exchange resin respectively, ensuring the sustainable use of the ion exchange resin. The cavity formed by the fixed refilling hole 1012, the rotating refilling hole 2021 and the liquid port 3011 can quickly perform the refilling work. At the same time, the structure can realize the lifting and closing of the fixed isolation net 302 by using the lifting and lowering sealing plate 502, which can prevent the fixed isolation net 302 from causing The mixing of positive and negative ion exchange liquids affects the water treatment effect of the ion exchange resin. Keeping the exchange liquid inside the positive ion exchange resin and the negative ion exchange resin working independently ensures that the positive ion exchange resin and the negative ion exchange resin always absorb only positive ion exchange liquid and negative ion exchange liquid. The control is simple and avoids the situation that when the positive and negative ion exchange liquid of the traditional mixed ion exchanger is replenished, the replenishment nozzle is mostly set between the positive and negative ion exchange resins. During actual replenishment, the stratification between the positive and negative ion exchange resins is not absolutely horizontal, and the positive and negative ion exchange resins located at the stratification are easy to mix, causing the positive ion exchange resin to absorb the negative ion exchange liquid or the negative ion exchange resin to absorb the positive ion exchange liquid.

[0044] In the disclosed embodiment, the magnetic control component 6 includes: a magnetic seat 601, a liquid-passing column 602, an electromagnet 603 and a sealing head 604.

At the same time, the shunt chamber 504 can be driven to move downward to align with the plugging head 604, so as to control the conduction of the shunt pipe 501 and perform temporary drainage, thereby ensuring that after the fixed isolation net 302 is closed and isolated, the wastewater after ion exchange can be discharged through the shunt pipe 501, thereby ensuring the continuity of wastewater treatment and avoiding the problem of normal drainage when replenishing the positive and negative ion exchange resins. This ensures that the present structure can replenish the positive and negative ion exchange resins without stopping the machine, and the structure is more reasonable. The present structure is simple to control, and when the electromagnet 603 magnetically attracts the magnetic iron ring 505 above, the shunt pipe 501 moves downward, driving the shunt chamber 504 to move downward. The inner diameter of the shunt chamber 504 is larger than the inner diameter of the shunt pipe 501. At this time, the diameter of the plugging head 604 cannot close the shunt chamber 504, and the treated wastewater can be discharged from the top of the shunt pipe 501.

[0045] Embodiment 2, on the basis of embodiment 1, the resin life test piece 7 comprises: a fixed cartridge frame 701, a lifting column 702 and a filter block 703, the filter block 703 is provided with a mesh; the fixed cartridge frame 701 is fixedly installed inside the shunt pipe 501; a circle of through holes is provided on the fixed cartridge frame 701; a lifting column 702 is slidably installed on the fixed cartridge frame 701; the plugging head 604 corresponds to the lifting column 702; the filter block 703 is fixedly installed on the lifting column 702; the filter block 703 is sleeved inside the fixed cartridge frame 701; the filter block 703 is used to filter impurities; the resin life The life test piece 7 also includes: a pressure sensor 704, an adapter spring 705 and a sliding plate 706. The HZC-H1 type pressure sensor 704 can be used, and a matching display is used. The pressure sensor 704 is fixedly installed inside the fixed cylinder frame 701; the pressure sensor 704 is externally connected to a display; the adapter spring 705 is located inside the fixed cylinder frame 701; the sliding plate 706 is slidably installed inside the fixed cylinder frame 701; the sliding plate 706 is attached to the end of the pressure sensor 704; the adapter spring 705 is connected between the sliding plate 706 and the lifting column 7 02, the resin life test piece 7 can be used to detect the service life of the positive and negative ion exchange resins, so as to avoid the positive and negative ion exchange resins from being undetected when they are broken, thereby ensuring the wastewater treatment quality of this structure. At the same time, this structure can perform comprehensive impurity detection on the three ion exchange parts 3 to ensure the comprehensiveness of the resin life detection of this structure. The wastewater quality can be detected by the filter block 703 to prevent excessive impurities in the wastewater from being undetected. During the actual detection, when the shunt pipe 501 moves downward, it can drive the lifting column 702 to move downward. If the positive and negative ion exchange resins are broken, the positive and negative ion exchange resins can be used to detect the impurities in the wastewater. If the resin is broken during replacement, the broken positive and negative ion exchange resins will leak through the mesh holes on the sealing plate 502. The sealing plate 502 will move down and will be blocked by the broken resin impurities and will not be completely in contact with the fixed isolation net 302. The corresponding elastic force value of the adapter spring 705 will change, which can be detected by the pressure sensor 704. If the impurity content of the wastewater is too high, the filter block 703 will be blocked. Then, under the action of the water pressure, the adapter spring 705 will be squeezed and compressed by the water pressure, and the elastic force will increase, which can be detected by the pressure sensor 704.

[0046] A method for treating industrial wastewater discharge:

[0047] 1) The water inlet pipe on the liquid inlet cover plate 102 is connected to the wastewater pump for water inlet. After the wastewater is exchanged with the positive and negative ion exchange resins in the two exchange installation cylinders 301 below, the treated industrial wastewater is discharged from the hose on the side of the exchange installation cylinder 301 below the drainage isolation cylinder 103 under the action of water pressure;

[0048] 2) Start the switching motor 201, drive the switching block 202 to drive the exchange installation cylinder 301 to rotate, switch the exchange installation cylinder 301 to align with the positive and negative ion replenishing component 4, and replenish the positive and negative ion replenishing liquid to the positive and negative ion exchange resin in the exchange installation cylinder 301 through the positive and negative ion replenishing component 4.

[0049] The working principle of this embodiment is as follows: first, the water inlet pipe on the liquid inlet cover plate 102 is connected to the wastewater pump for water inlet. After the wastewater passes through the positive and negative ion exchange resins in the two exchange mounting cylinders 301 below for ion exchange, the treated industrial wastewater is discharged from the exchange mounting cylinder 301 located below the drainage isolation cylinder 103 under the action of water pressure, and is discharged through the drainage hose on the side of the drainage isolation cylinder 103. During the process, the positive and negative ion exchange resins inside the exchange mounting cylinder 301 located at the drainage isolation cylinder 103 will be washed with water, which is convenient for subsequent replenishment of ion exchange liquid. After the capacity of the positive and negative ion exchange resins in the two exchange mounting cylinders 301 located at the water inlet end is reduced, the switching motor 201 can be started to drive the switching block 202 to drive the exchange mounting cylinder 301 to rotate and switch to the bottom of the drainage isolation cylinder 103, which is convenient for replenishing the liquid after cleaning. In this way, the waste liquid treatment and the replenishing of the positive and negative ion exchange resins after washing are continuously carried out; the magnetic iron ring 505 above is magnetically attracted by the electromagnet 603 to control the lower part of the shunt pipe 501 The sealing plate 502 is moved to close the fixed isolation net 302 with misaligned meshes to avoid mixing of positive and negative supplementary liquids. The positive and negative ion supplementary liquid pumps connected to the two supplementary liquid tubes 402 are respectively started to pump an appropriate amount of supplementary liquid between a row of fixed isolation nets 302; when the magnetic iron ring 505 is obtained by the magnetic attraction of the electromagnet 603, the shunt tube 501 moves downward, driving the shunt chamber 504 to move downward. At this time, the shunt chamber 504 is inserted into the plugging head 604, and the plugging head 604 is no longer sealed and fitted. The magnetic iron ring 505 is closed because the inner diameter of the shunt chamber 504 is larger than the inner diameter of the shunt tube 501. At this time, the diameter of the plugging head 604 cannot close the shunt chamber 504. At this time, the treated wastewater can flow into the shunt chamber 504 from a circle of through holes on the liquid column 602, and then be discharged from the top of the shunt tube 501 and then through the drainage hose on the side of the drainage isolation cylinder 103. The two shielding plates 1011 used can block the top of the shunt tube 501 below in real time to seal and prevent leakage.

[0050] If the positive and negative ion exchange resins are broken, the broken positive and negative ion exchange resins will leak from the mesh holes on the sealing plate 502. At this time, resin impurities will remain between the upper part of the fixed isolation net 302 and the sealing plate 502. At this time, the sealing plate 502 will not be completely in contact with the fixed isolation net 302 when it moves downward, and the corresponding downward movement distance of the lifting column 702 will be shortened. The lifting column 702 moves downward and touches the plugging head 604, but the downward pressure stroke of the lifting column 702 is short, and the compression amount of the adapter spring 705 is reduced, and the corresponding elastic force value of the adapter spring 705 will change, which can be detected by the pressure sensor 704. The reading of the pressure sensor 704 is better than the normal value. If the value decreases, it means that resin impurities are retained between the top of the fixed isolation net 302 and the sealing plate 502. At the same time, the filter block 703 can be used to filter the impurities. If the impurity content of the wastewater is too high, the filter block 703 is provided with a mesh. At this time, the mesh of the filter block 703 will be partially blocked. Then, under the action of water pressure, the filter block 703 will drive the lifting column 702 to rise and compress the adapter spring 705. The adapter spring 705 is squeezed and compressed by the water pressure, and the elastic force is increased. It can be detected by the pressure sensor 704, and the value can be displayed in real time by the display external to the pressure sensor 704, so as to control the water quality of the incoming water in time and clean the filter block 703.
