Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an adsorption tower for wastewater treatment. Background Technology

[0002] Wastewater adsorption towers are environmental protection devices that remove pollutants from water using the principle of adsorption. They are mainly used for the deep purification treatment of industrial wastewater, domestic sewage, and in specific scenarios (such as laboratories). Existing wastewater adsorption tower technologies have the following problems:

[0003] With only horizontally installed multi-layer adsorption, large particles of organic matter can easily clog the top layer of wastewater during vertical transport, eventually causing blockage and hindering wastewater flow. This may require frequent replacement of the top layer.

[0004] Therefore, it is necessary to develop an adsorption tower for wastewater treatment to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to design an adsorption tower for wastewater treatment in order to solve the above problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] Adsorption towers for wastewater treatment include:

[0008] The outer casing has a water inlet at its upper end.

[0009] Motor; the motor is mounted upside down on top of the housing;

[0010] Shaft; The motor's shaft passes through the top of the housing and connects to the upper end of the connecting shaft;

[0011] Paddle plate; the paddle plate is mounted on the connecting shaft;

[0012] Multiple large particle adsorption screens; multiple mounting slots are provided on the side wall of the outer shell, and multiple large particle adsorption screens are respectively inserted into multiple mounting slots, and multiple mounting slots are all vertically arranged.

[0013] The first adsorption layer, the second adsorption layer, and the third adsorption layer are arranged sequentially from top to bottom; the first adsorption layer is a pretreatment layer; the second adsorption layer is a main treatment layer; and the third adsorption layer is a deep treatment layer; an outlet is provided on the side wall of the outer shell located below the third adsorption layer.

[0014] The beneficial effects of this utility model are as follows:

[0015] In use, this application sets multiple large particle adsorption screens on the inner wall of the shell, and then drives the rotating shaft and slurry plate to rotate by the motor. The rotation of the slurry plate agitates the sewage, and large particle impurities containing organic matter are filtered by the large particle adsorption screens, preventing large particle impurities from entering the uppermost adsorption layer and causing blockage. Moreover, the large particle adsorption screens in this application are more convenient to replace than the uppermost adsorption layer inside the shell. Attached Figure Description

[0027] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figure 1 As shown, the adsorption tower for wastewater treatment includes:

[0029] Outer casing 1; an inlet 2 is provided at the upper end of outer casing 1;

[0030] Motor 4; Motor 4 is mounted upside down on top of housing 1;

[0031] Shaft; The shaft of motor 4 passes through the top of housing 1 and is connected to the upper end of connecting shaft 5;

[0032] Paddle plate 6; Paddle plate 6 is mounted on connecting shaft 5;

[0033] Four large particle adsorption screens 7; four mounting slots are provided on the side wall of the outer shell 1, and the four large particle adsorption screens 7 are respectively inserted into the four mounting slots. All four mounting slots are vertically arranged; the four large particle adsorption screens 7 are evenly distributed around the axis of the outer shell 1; the slurry plate 6 is arranged between the multiple large particle adsorption screens 7.

[0034] The first adsorption layer 8, the second adsorption layer 9, and the third adsorption layer 10 are arranged sequentially from top to bottom; the first adsorption layer 8 is a pretreatment layer; the second adsorption layer 9 is a main treatment layer; the third adsorption layer 10 is a deep treatment layer; and the outer shell 1 has an outlet 3 on the side wall below the third adsorption layer 10.

[0035] In some embodiments, the upper end of the large particle adsorption screen 7 is higher than the highest water level, so that when the slurry plate 6 agitates the sewage, the large particle adsorption screen 7 can still adsorb most of the floating objects.

[0036] like Figure 4 As shown, the large particle adsorption screen 7 includes a connecting plate 18, a mounting frame 22, an adsorption screen 23, a sealing ring 20, four first bolts 19, and two second bolts 24. The mounting frame 22 is a rectangular frame structure with vertical mounting holes inside. The adsorption screen 23 is inserted into the mounting frame 22 for installation. The mounting frame 22 is inserted into the mounting slot. The first side of the mounting frame 22 is connected to the connecting plate 18. A mounting groove is provided on the first side of the connecting plate 18, and the sealing ring 20 is placed in the mounting groove. When the large particle adsorption screen 7 is installed, the first side of the connecting plate 18 is in close contact with the outer wall of the outer shell 1. The four first bolts 19 are screwed into the four corners of the connecting plate 18 and then threadedly connected to the outer shell 1. The two second bolts 24 are screwed into the mounting frame 22 from the top and bottom of the second side and then press against the top and bottom of the adsorption screen 23. The first side and the second side of the mounting frame 22 are two opposite sides. In this embodiment, when the connecting plate 18 and the outer shell 1 are tightened by the first bolt 19, the sealing ring 20 is compressed. The function of the sealing ring 20 is to prevent sewage leakage. By loosening the first bolt 19 and disconnecting the connection between the first bolt 19 and the outer shell 1, the large particle adsorption screen 7 can be removed. By loosening the second bolt 24 and disconnecting the end of the second bolt 24 from the side of the adsorption screen 23, the adsorption screen 23 can be pulled out for replacement.

[0037] like Figure 4 As shown, a handle 21 is installed on the second side of the connecting plate 18, and the first and second sides of the connecting plate 18 are opposite to each other. The handle 21 makes it easier to pull out and put in the large particle adsorption screen 7.

[0038] like Figure 4 As shown, the inner wall of the connecting plate 18 has an arc-shaped structure that mates with the outer wall. This structural design is to ensure a closer fit between the connecting plate 18 and the side wall of the outer shell 1.

[0039] In some embodiments, the first adsorption layer 8 is provided with quartz sand, which is mainly used to intercept suspended solids, particulate matter and macromolecular organic matter; the second adsorption layer 9 is provided with granular activated carbon, which undertakes the core adsorption function and can efficiently remove dissolved organic matter, color and some heavy metal ions; the third adsorption layer 10 is provided with modified activated carbon, which specifically adsorbs recalcitrant substances (such as benzene series compounds, halogenated hydrocarbons, etc.) and reduces the residual concentration of effluent.

[0040] like Figure 1 As shown, the adsorption tower also includes a first detector 11, a second detector 12, and a third detector 13. A first gap is provided between the first adsorption layer 8 and the second adsorption layer 9, and a second gap is provided between the second adsorption layer 9 and the third adsorption layer 10. The sampling end of the first detector 11 is connected to the first gap, the sampling end of the second detector 12 is connected to the second gap, and the sampling end of the third detector 13 is connected to the interior of the outer shell 1 below the third adsorption layer 10. The first detector 11 is used to detect whether the water quality after treatment by the first adsorption layer 8 meets the standard, and to determine whether the first adsorption layer 8 needs to be replaced; the second detector 12 is used to detect whether the water quality after treatment by the second adsorption layer 9 meets the standard, and to determine whether the second adsorption layer 9 needs to be replaced; the third detector 13 is used to detect whether the water quality after treatment by the third adsorption layer 10 meets the standard, and to determine whether the third adsorption layer 10 needs to be replaced. The first detector 11, the second detector 12, and the third detector 13 are all water quality testing instruments, which are existing technologies and will not be described in detail here.

[0041] like Figure 2 As shown, the first adsorption layer 8, the second adsorption layer 9, and the third adsorption layer 10 each include a first mounting grid plate 14, a second mounting grid plate 15, and a third mounting grid plate 16 arranged sequentially from top to bottom, with the pore size of the first mounting grid plate 14, the second mounting grid plate 15, and the third mounting grid plate 16 decreasing sequentially. Through the tree-like fractal water distribution structure of this application, the fractal distribution of plant roots is simulated, optimizing the water flow path, allowing untreated wastewater to enter easily, and reducing the possibility of blockage.

[0042] like Figure 3 As shown, the holes 17 on the first mounting grid plate 14, the second mounting grid plate 15, and the third mounting grid plate 16 are all honeycomb holes. This structural design mimics the hexagonal structure of a honeycomb, increasing the specific surface area and mechanical strength.

[0043] Working principle: During operation, wastewater enters through inlet 2, then motor 4 starts, driving connecting shaft 5 to rotate. Connecting shaft 5 then drives slurry plate 6 to rotate, agitating the water flow. The agitated water flows through large particle adsorption screen 7, filtering out large particles containing organic matter. Under gravity, the wastewater continues downwards, sequentially passing through the first adsorption layer 8, the second adsorption layer 9, and the third adsorption layer 10 before being discharged through outlet 3. When the first detector 11, the second detector 12, or the third detector 13 detects an abnormality, the corresponding adsorption layer is replaced according to the corresponding relationship.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
