Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a multi-effect treatment system for ammonia-containing wastewater. Background Technology

[0002] The process of producing creatine monohydrate from hydroxyacetonitrile generates a large amount of ammonia-containing wastewater. Direct discharge of this wastewater will cause environmental pollution and waste of ammonia resources. Therefore, it is necessary to treat the ammonia-containing wastewater and recover the ammonia.

[0003] Chinese patent discloses an ammonia recovery and treatment device for ammonia-containing industrial wastewater, publication number CN222118967U. The paper states that "this utility model includes an ammonia removal tower, with an inlet pipe at the top, an outlet pipe on the outer surface of the bottom, an outlet pipe on the outer surface of the top, and an outlet pipe on the outer surface of the bottom. The top and outer surfaces of the ammonia removal tower are each equipped with a replacement device. This replacement device includes a locking rod, a threaded rod, two threaded blocks, a sealing block, an elastic locking block, and two pads. One end of the locking rod is connected to the outer surface of the ammonia removal tower via a detachable device. By providing this replacement device, when the sealing block needs to be replaced, it is not necessary to remove the conveying pipe from the inlet pipe, thus improving replacement efficiency and ammonia removal efficiency."

[0004] However, in the above scheme, some impurities will settle on the bottom wall of the tower, which will increase the difficulty of subsequent cleaning. Excessive impurities will affect the subsequent treatment effect. At the same time, the wall flow effect is likely to occur, which will reduce the effect of subsequent treatment. Therefore, it is necessary to design a multi-effect treatment system for ammonia-containing wastewater. Utility Model Content

[0021] Example 1 A preferred embodiment of the multi-effect treatment system for ammonia-containing wastewater provided by this utility model is, for example... Figures 1 to 5 The diagram shows a multi-effect treatment system for ammonia-containing wastewater, comprising: a tower body 2; a drain pipe 8 fixedly connected to one side of the bottom of the tower body 2; an aeration disc 11 fixedly connected to the lower end of the inner wall of the tower body 2; an air inlet pipe 7 fixedly connected to one side of the aeration disc 11 extending to the outside of the tower body 2; a drain pipe 10 fixedly connected to one side of the tower body 2 below the aeration disc 11; a cleaning assembly 9 assembled at the bottom of the inner wall of the tower body 2, used to scrape and clean the sediment on the bottom wall of the inner wall of the tower body 2; a packing seat 6 fixedly connected to the lower end of the inner wall of the tower body 2, with connecting holes 12 at equal angles on the packing seat 6; a water distribution disc 13 fixedly connected to the inner wall of the tower body 2 above the packing seat 6; an air inlet pipe 3 fixedly connected to the top of the water distribution disc 13 extending to the outside of the tower body 2; an adsorption box 14 fixedly connected to the top of the tower body 2; an exhaust pipe 15 fixedly connected to the top of the adsorption box 14; and an adsorption assembly 1 assembled inside the adsorption box 14, used to re-adsorb and treat the discharged gas.

[0022] It should be noted that some existing multi-effect treatment systems for ammonia-containing wastewater still have certain shortcomings in actual use. Some impurities will settle on the bottom wall of the inner tower 2, which will increase the difficulty of subsequent cleaning. Excessive impurities will affect the subsequent treatment effect. At the same time, the wall flow effect is prone to occur, which will reduce the effect of subsequent treatment.

[0023] In a further preferred embodiment of this utility model, the cleaning component 9 includes: a servo motor 901 fixedly connected to the middle position of the bottom end of the tower body 2, a rotating rod 903 that penetrates the interior of the tower body 2 fixedly connected to the output end of the servo motor 901, and a second bolt hole 902 opened at the top end of the rotating rod 903; a fixing sleeve 906 movably connected to the top end of the rotating rod 903, a cleaning scraper 904 fixedly connected to one side of the fixing sleeve 906, and a second fixing bolt 907 that is threadedly engaged with the interior of the second bolt hole 902 movably connected to the top end of the fixing sleeve 906.

[0024] In this embodiment, the servo motor 901 is started to drive the rotating rod 903 to rotate, which in turn causes the fixed sleeve 906 to rotate and drive the cleaning scraper 904 to rotate, so as to scrape the impurities deposited on the inner wall of the tower body 2 and make them easy to be discharged through the drain pipe 8.

[0025] In a further preferred embodiment of this utility model, one side of the cleaning scraper 904 is arc-shaped, and the bottom end of the cleaning scraper 904 is in contact with the inner bottom wall of the tower body 2.

[0026] In a further preferred embodiment of the present invention, a slot 908 is provided on one side of the top end of the rotating rod 903, and a locking block 905 that engages with the inside of the slot 908 is fixedly connected to the inner wall of the fixing sleeve 906.

[0027] In this embodiment, the engagement between the locking block 905 and the slot 908 improves the stability of the engagement installation of the fixing sleeve 906 and the cleaning scraper 904 with the top of the rotating rod 903.

[0028] In a further preferred embodiment of this utility model, the top of the packing seat 6 is bowl-shaped, and a spiral groove 4 is provided on the inner wall of the tower body 2 above the packing seat 6.

[0029] In this embodiment, the spiral groove 4 is used to guide the water flowing along the wall towards the center of the tower body 2, instead of letting it fall in a straight line. Furthermore, the top of the packing seat 6 is truncated cone-shaped, which further disperses the accumulated water and prevents the wall flow effect.

[0030] In a further preferred embodiment of this utility model, the inner wall of the packing seat 6 is fixedly connected with fixing blocks 5 at equal intervals and crosses, and the angle of inclination of the fixing blocks 5 with the horizontal direction is forty degrees.

[0031] In this embodiment, the inclined fixing block 5 can effectively prolong the contact time between the gas and the wastewater, thereby increasing the reaction time.

[0032] Example 2 Based on Example 1, a preferred embodiment of the multi-effect treatment system for ammonia-containing wastewater provided by this utility model is as follows: Figures 1 to 5As shown in the figure: The adsorption component 1 includes: an installation groove 107 opened on the front surface of the adsorption box 14, and first bolt holes 102 are opened on the front surface of the adsorption box 14 above and below the installation groove 107; a sealing plate 101 movably connected to the front surface of the adsorption box 14, and first fixing bolts 105 that are threadedly engaged with the inside of the first bolt holes 102 are movably connected to both sides of the front surface of the sealing plate 101, and an activated carbon adsorption plate 106 extending into the adsorption box 14 is fixedly connected to the back surface of the sealing plate 101.

[0033] In this embodiment, by using the activated carbon adsorption plate 106, the upwardly conveyed gas can be further adsorbed and treated, improving the treatment effect of the ammonia-containing wastewater. At the same time, the activated carbon adsorption plate 106 with saturated adsorption can be slid out through the sealing plate 101, facilitating the removal and replacement of the saturated activated carbon adsorption plate 106.

[0034] In a further preferred embodiment of the present invention, a sealing ring 103 is fixedly connected to one end of the surface of the sealing plate 101, and the shape of the sealing ring 103 is a square frame.

[0035] In this embodiment, by using the square frame-shaped sealing ring 103, the sealing performance of the sealing plate 101 engaged and installed inside the installation groove 107 is improved.

[0036] In a further preferred embodiment of the present invention, anti-slip lines 104 are equally angled on the surface of the nut of the first fixing bolt 105, and the shape of the anti-slip lines 104 is an arc.

[0037] In this embodiment, by using the arc-shaped anti-slip lines 104, the anti-slip friction force between the user's finger and the nut of the first fixing bolt 105 during rotation is improved.

[0038] In summary, first, the water inlet pipe 3, the air inlet pipe 7, the sewage discharge pipe 8, the drain pipe 10, and the exhaust pipe 15 are respectively connected to external pipes. Then, the external ammonia-containing wastewater is conveyed to the inside of the water distribution tray 13 through the water inlet pipe 3 and evenly distributed by the water distribution tray 13. At the same time, external gas is conveyed by the air inlet pipe 7 and evenly distributed by the aeration tray 11, so as to react with the falling wastewater. At the same time, by using the inclined fixing block 5, the contact time between the gas and the wastewater can be effectively extended, improving the reaction time; The gas is then conveyed upwards into the adsorption box 14. At this point, the activated carbon adsorption plate 106 further adsorbs and treats the upward-conveyed gas, improving the treatment effect on ammonia-containing wastewater. Simultaneously, the first fixing bolt 105 can be rotated until it is completely disengaged from the first bolt hole 102. Then, the activated carbon adsorption plate 106 can be slid out through the sealing plate 101, making it easy to remove and replace the saturated activated carbon adsorption plate 106. During installation, the activated carbon adsorption plate 106 is placed inside the adsorption box 14, and the sealing plate 101 is locked into the mounting groove 107. The sealing ring 103 is used to improve the sealing performance of the sealing plate 101 and the mounting groove 107. Finally, the first fixing bolt 105 is tightened into the first bolt hole 102. Furthermore, as the reaction proceeds, some wastewater will accumulate on the inner wall of the tower body 2 and flow downwards. At this time, the spiral groove 4 is used to guide the water flowing on the wall towards the center of the tower body 2, instead of letting it fall in a straight line. In addition, the top of the packing seat 6 is truncated cone-shaped, which further disperses the accumulated water and prevents the wall flow effect. Then, open the valve on the drain pipe 8 to discharge the wastewater. At the same time, start the servo motor 901 to drive the rotating rod 903 to rotate, which in turn causes the fixed sleeve 906 to rotate and drive the cleaning scraper 904 to rotate, so as to scrape the impurities deposited on the inner wall of the tower body 2 and make them easy to be discharged through the drain pipe 8.
