Description

Technical Field

[0001] This invention relates to the field of nickel-containing wastewater treatment technology, and in particular to wastewater treatment equipment based on the recycling and cleaning of old nickel mesh. Background Technology

[0002] During pickling or electrolytic cleaning, dirt and loose nickel layers on the surface of old nickel mesh are stripped away, causing nickel to leak into the cleaning solution in ionic or particulate form, resulting in significant nickel metal loss. Therefore, nickel recovery is necessary to reduce resource waste and environmental pollution. Current technology uses ion exchange resin: wastewater is injected from the top of the resin column, and the upper layer of resin preferentially adsorbs high concentrations of nickel ions, with a higher adsorption capacity than the lower layer. When the upper layer is saturated, the entire column needs to be regenerated. However, the uniform regeneration process leads to the waste of unsaturated resin in the lower layer and accelerates its lifespan decline. Because the number of regeneration cycles is limited, this method results in the waste of some ion exchange resin. Summary of the Invention

[0035] The controller 13 is electrically connected with the motor 415, the electromagnetic valves one, two, three, four, five and six.

[0036] Working principle: The sewage pump injects sewage into the interiors of the annular water troughs one 32 through the plurality of sewage feeding pipes one 34, the sewage then enters the plurality of communicated shunt tanks one 31 through the sewage feeding pipes two 37, and is then delivered into the uppermost circular tank 21 through the dispersion pipe set one 36. The sewage penetrates the ion exchange resin layer filled between the plurality of partitions 23, the resin exchanges and adsorbs the nickel ions in the sewage. The butt joint frame 25 closes one of the regeneration spaces. After the sewage penetrates the resin layer of the circular tank 21, it enters the annular water trough three 46 through the sewage feeding pipe three 44, and then flows into the shunt tank two 47 through the sewage feeding pipe four 49, and then enters the middle circular tank 21 through the dispersion pipe set two 411. The sewage penetrates the plurality of spaces of the middle circular tank 21, and further exchanges ions with the corresponding resin, and then enters the lower circular tank 21 through the bottom feeding butt joint mechanism 3 for the final exchange. The exchanged sewage is collected into the annular water trough five 56 through the sewage discharging pipe one 54, and is finally discharged out of the barrel 11 through the sewage discharging pipe two 57. When the system runs for a certain period of time, the adsorption saturation of the resin in the three circular boxes 21 presents a gradient difference: the uppermost circular box 21 has the highest saturation because it is the first to contact the sewage, the middle circular box 21 is the second, and the lower circular box 21 has the lowest saturation. In order to ensure the service life of the resin (limited number of regeneration times), the regeneration frequency needs to be strictly controlled. When the uppermost layer of resin reaches the specified service life, the motor 415 is started to drive the rotating shaft two 412 and the plurality of gears two 413 to rotate. The gears two 413 drive the gears one 414, the circular boxes 21, the partitions 23, the rotating shaft one 22 and the internal resin to rotate synchronously by a specified angle, so that the resin between the two partitions 23 adjacent to the docking frame 25 is moved to the position directly below the docking frame 25. The space originally serves as an exchange station, and the electromagnetic valve one in the sewage feed pipe three 44 is in an open state. After rotating to the regeneration station, the controller 13 closes the electromagnetic valve one of the sewage feed pipe three 44 corresponding to the space to prevent the regeneration liquid from flowing into the annular tank three 46 to interfere with the exchange in other areas; at the same time, the electromagnetic valve two of the regeneration liquid feed pipe two 41 and the electromagnetic valve three of the regeneration liquid discharge pipe one 48 are opened to make the regeneration liquid flow into the annular tank two 43. At this time, the saturation of the resin in the middle circular box 21 is insufficient, so the electromagnetic valve four of the regeneration liquid inlet pipe three 410 remains closed. The regeneration liquid carrying nickel ions is discharged through the annular tank two 43 and the regeneration liquid discharge pipe one 48. After cleaning, wait for a specified time, and then start the motor 415 again to rotate the regenerated resin out of the station and put it into operation, while rotating the next space to the regeneration station. Because the rotating speed ratio of the three circular boxes 21 decreases from top to bottom along the axial direction as 4:2:1, when the first space of the uppermost circular box 21 is completed, the corresponding space of the middle circular box 21 only rotates half, and the corresponding space of the lower circular box 21 only rotates one fourth. When the second space of the uppermost circular box 21 rotates to the regeneration station, the corresponding space of the middle circular box 21 is synchronously fully positioned, while the lower circular box 21 only rotates to the half station. At this time, the electromagnetic valve four of the regeneration liquid inlet pipe three 410 at the top of the middle circular box 21 is opened, and the electromagnetic valve three of the regeneration liquid discharge pipe one 48 is closed, so that the upper regeneration liquid flows into the middle cleaning resin, and then is discharged through the regeneration liquid feed pipe two 41 at the bottom of the middle layer, the annular tank two 43 and the regeneration liquid discharge pipe one 48. When the upper circular box 21 rotates four spaces and the middle layer rotates two spaces, the lower circular box 21 rotates exactly one space to the regeneration station. At this time, the electromagnetic valve four is started to connect the middle layer and the lower layer regeneration station, the electromagnetic valve five is opened and the electromagnetic valve six is closed to regenerate the lower resin. The regeneration liquid is finally discharged through the regeneration liquid discharge pipe two 51, the annular tank four 53 and the regeneration liquid discharge pipe three 58. Subsequently, the motor 415 is started again to drive the three circular boxes 21 to rotate synchronously to dock other regeneration spaces. It needs to be particularly pointed out that when the space is not fully rotated to the regeneration station, the electromagnetic valve four of the regeneration liquid inlet pipe three 410 is in a closed state, so it does not affect the process of exchanging nickel ions in the sewage. The present application realizes high-efficiency separation of nickel ions in sewage and automatic regeneration process of ion exchange resin by installing a sub-area processing mechanism 2 which divides the sewage treatment area into multiple independent units; when a part of the units perform nickel separation of sewage, another part of the units performs resin regeneration operation, thereby ensuring that the system does not need to be shut down for maintenance during the regeneration process, significantly reducing the processing interruption time, and greatly improving the overall efficiency and continuous operation capacity of the sewage treatment. The present application sets a regeneration frequency control mechanism 4 which, based on the characteristics of different layer concentration differences, uses the speed ratio to make the multi-layer ion exchange resin produce differential rotation, thereby regulating the frequency of each layer of resin entering the regeneration station, effectively preventing over-regeneration, and significantly prolonging the service life of the ion exchange resin.

[0037] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change within the technical range disclosed by the present application according to the technical solution and inventive concept of the present application, which should be covered within the protection scope of the present application.
