Description

[0002] Heavy metal wastewater treatment refers to the process of removing heavy metals from heavy metal wastewater and recycling or rendering them harmless. Heavy metal wastewater is generated in many production processes in industries such as mining, machinery manufacturing, chemicals, electronics, and instrumentation. For example, metal surface processing, particularly electroplating, produces rinse water and plating tank wastewater containing heavy metals such as chromium, cadmium, copper, zinc, and nickel, as well as cyanide.

[0003] Adsorption tower is a commonly used adsorption resin carrier for adsorption method. Adsorption resin can be directly loaded inside the adsorption tower, and then the heavy metal wastewater is controlled to flow in and out, thereby realizing the treatment of heavy metal wastewater.

At this time, adsorption resin is loaded between the upper water cap and the lower water cap, and the heavy metal wastewater is controlled to flow in and out, and the treatment of heavy metal wastewater is realized by reflux. However, the above-mentioned existing adsorption towers either have a large floor space or a large power consumption, and are unable to meet the development needs of wastewater treatment.

[0036] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0038] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0040] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0041] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0042] See Figure 1 As shown, the present application provides an adsorption tower, which includes an equipment main body 1000 and a separator 1100. A processing chamber 1000a is provided inside the equipment main body 1000. The shape, size and volume of the processing chamber 1000a can be set according to needs and are not limited here. Among them, a water inlet 1000b and a water outlet 1000c connected to the processing chamber 1000a are provided on the equipment main body 1000. The water inlet 1000b is used to introduce the target fluid to be treated into the processing chamber 1000a, and the water outlet 1000c is used to discharge the target fluid treated by the processing chamber 1000a. The target fluid to be treated is wastewater containing heavy metals or other wastewater that needs to be treated. It is not limited here. Unless otherwise specified below, the target fluid referred to as the target fluid is the target fluid being treated in the equipment main body 1000. Therefore, the target fluid to be processed is introduced into the processing chamber 1000a from the water inlet 1000b for processing, and then discharged from the water outlet 1000c after processing, thereby obtaining the processed target fluid.

[0043] The partition 1100 is disposed in the processing chamber 1000a of the device body 1000 and can divide the processing chamber 1000a of the device body 1000 into N interconnected unit chambers, where N>1 and N is an integer. For example, the partition 1100 can divide the processing chamber 1000a of the device body 1000 into two unit chambers, three unit chambers, or a greater number of unit chambers, and all of the unit chambers are interconnected. In this case, the water inlet 1000b and the water outlet 1000c are each connected to one of the N unit chambers, so that the water inlet 1000b and the water outlet 1000c are respectively connected to different unit chambers.

[0044] In addition, a fluid motion trajectory is defined within the processing chamber 1000a of the device body 1000. This fluid motion trajectory is a virtual trajectory used to define the flow direction of the target fluid within the processing chamber 1000a of the device body 1000. It represents the direction of the target fluid's flow within the processing chamber 1000a of the device body 1000 as the target fluid enters the processing chamber 1000a of the device body 1000 from the water inlet 1000b, undergoes treatment, and then flows out of the water outlet 1000c. It should be noted that this fluid motion trajectory reflects the overall flow direction of the target fluid and does not represent any unintended flow trajectory of the target fluid within the processing chamber 1000a due to, for example, collisions with the inner wall.

[0045] For example, the starting point of the fluid motion trajectory is located at the water inlet 1000b of the device body 1000, and the end point of the fluid motion trajectory is located at the water outlet 1000c of the device body 1000. The fluid motion trajectory sequentially passes through n unit chambers within the processing chamber 1000a of the device body 1000. The fluid motion trajectory is used to define the flow direction of the target fluid to be processed through the water inlet, n unit chambers, and the water outlet, where 1 < n ≤ N and n is an integer.

[0046] Based on the above settings, N represents the number of unit chambers separated from the processing chamber 1000a of the device body 1000, and n represents the number of unit chambers actually used when processing the target fluid. Therefore, 1<n≤N. For example, when N=5 and n=3, it means that there are 5 unit chambers separated from the processing chamber 1000a of the device body 1000, but when processing the target fluid, only 3 of the 5 unit chambers are used to meet the processing expectations; when N=5 and n=5, it means that there are 5 unit chambers separated from the processing chamber 1000a of the device body 1000, but when processing the target fluid, all 5 unit chambers need to be used to meet the processing expectations.

[0047] Therefore, the above fluid motion trajectory indicates that the target fluid to be processed enters the processing chamber 1000a connected to the water inlet 1000b from the water inlet 1000b, passes through the n unit chambers that are actually set up and need to be used in turn, and then is discharged from the processing chamber 1000a connected to the water outlet 1000c through the water outlet 1000c. Therefore, the total n unit chambers passed through in this process can be part of the N unit chambers (n<N) or all of the N unit chambers (n=N).

[0048] During the aforementioned flow process, as the target fluid enters the treatment chamber 1000a from the water inlet 1000b and passes through the n unit chambers, it can fully contact the adsorbent in each unit chamber. This increases the contact time between the target fluid and the adsorbent in the treatment chamber 1000a, resulting in sufficient treatment of the target fluid before it is discharged from the water outlet 1000c. This process increases the contact time between the adsorbent and the target fluid (heavy metal-containing wastewater), thereby enhancing the adsorption efficiency of heavy metals. Furthermore, during operation, only the target fluid needs to be controlled to move along the fluid motion trajectory within the treatment chamber 1000a of the device body 1000. Therefore, only the inlet and outlet pumps are required, eliminating the need for reflux pumps, transfer pumps, agitators, and other pumping equipment. This effectively reduces electricity consumption during operation. Because the aforementioned structural design improves the adsorption tower's adsorption efficiency for heavy metals through structural improvements within the adsorption tower, the adsorption tower can treat more wastewater within the same tower volume. Therefore, under the same wastewater treatment conditions, the tower volume can be reduced, thereby reducing the floor space required.

[0049] See Figure 1 As shown, the water inlet 1000b and the water outlet 1000c are both located at the bottom of the apparatus body 1000, and each of the water inlet 1000b and the water outlet 1000c is connected to the bottom of a unit chamber. In this embodiment, the fluid motion trajectory includes at least one upward flow trajectory from the bottom of the apparatus body 1000 to the top of the apparatus body 1000 in the processing chamber 1000a, and at least one downward flow trajectory from the top of the apparatus body 1000 to the bottom of the apparatus body 1000 in the processing chamber 1000a.

[0050] Among them, all of the upward flow trajectories and all of the downward flow trajectories can be cross-connected in series, so that the starting point of the upward flow trajectory at the head end is located at the water inlet, and the end point of the downward flow trajectory at the tail end is located at the water outlet. Between the upward flow trajectory at the head end and the downward flow trajectory at the tail end, the tail end of each upward flow trajectory is connected to the starting end of the next adjacent downward flow trajectory. Therefore, the target fluid to be processed enters the processing chamber 1000a connected to the water inlet 1000b from the water inlet 1000b at the bottom of the equipment body 1000, so that the target fluid passes through n unit chambers in sequence along the upward flow trajectory and the downward flow trajectory, and finally is discharged from the processing chamber 1000a connected to the water outlet 1000c through the water outlet 1000c.

[0051] In one embodiment, a partition 1100 is connected to the inner wall of the processing chamber 1000a, dividing the processing chamber 1000a of the apparatus body 1000 into a first unit chamber 1001a and a second unit chamber 1002a, which are interconnected. The water inlet 1000b is connected to the bottom of the first unit chamber 1001a, and the water outlet 1000c is connected to the bottom of the second unit chamber 1002a. Therefore, the target fluid to be processed enters the first unit chamber 1001a through the water inlet 1000b at the bottom, flows from the first unit chamber 1001a toward the top of the apparatus body 1000, enters the second unit chamber 1002a from the top, and then flows from the top of the apparatus body 1000 toward the bottom of the apparatus body 1000 in the second unit chamber 1002a, and finally flows out through the water outlet 1000c at the bottom of the second unit chamber 1002a.

[0052] In this embodiment, the fluid motion trajectory may include an upward flow trajectory and a downward flow trajectory. The upward flow trajectory starts at the water inlet 1000b, and the upward flow trajectory runs from the bottom of the first unit chamber 1001a to the top of the first unit chamber 1001a within the first unit chamber 1001a. The upward flow trajectory ends at the top of the first unit chamber 1001a. The downward flow trajectory starts at the top of the second unit chamber 1002a, and the starting point of the downward flow trajectory is connected to the end point of the upward flow trajectory. The downward flow trajectory runs from the top of the second unit chamber 1002a to the bottom of the second unit chamber 1002a within the second unit chamber 1002a, and the end point of the downward flow trajectory is located at the water outlet 1000c. Therefore, the target fluid can first flow along the upward flow trajectory and then flow along the downward flow trajectory. Therefore, the target fluid to be treated can fully contact the adsorbent in both the first unit chamber 1001a and the second unit chamber 1002a, increasing the contact time between the target fluid and the adsorbent in the treatment chamber, ensuring full treatment of the target fluid and improving the adsorption effect on heavy metals. Furthermore, during operation, it is only necessary to control the movement of the target fluid along the fluid motion trajectory within the treatment chamber of the device body. Therefore, only the inlet and outlet pumps are involved, and no return pumps, transfer pumps, agitators, or other pumping equipment are involved. This effectively saves electricity consumption during operation.

[0053] Continue reading Figure 1 As shown, in one embodiment, the adsorption tower includes a plurality of first water caps 3001, a plurality of second water caps 3002, a plurality of third water caps 3003, and a plurality of fourth water caps 3004. The plurality of first water caps 3001 are disposed at the bottom of the first unit chamber 1001a, the plurality of second water caps 3002 are disposed at the top of the first unit chamber 1001a, the plurality of third water caps 3003 are disposed at the top of the second unit chamber 1002a, and the plurality of fourth water caps 3004 are disposed at the bottom of the second unit chamber 1002a.

[0054] The working principle of the water cap is to use the surface tension and gravity of water to guide water from a high point to a low point, thereby achieving a waterproof effect. Therefore, the distribution of the first water cap 3001, the second water cap 3002, the third water cap 3003, and the fourth water cap 3004 in the first unit chamber 1001a and the second unit chamber 1002a can be used to guide the target fluid along the fluid motion trajectory in the first unit chamber 1001a and the second unit chamber 1002a. The target fluid is treated as it passes through the first unit chamber 1001a and the second unit chamber 1002a and is ultimately discharged from the adsorption tower after treatment. The water cap can be made of rubber or silicone, etc.

The second pump body is connected to the water outlet 1000c via a second fluid delivery pipe 2002, and is used to discharge the treated target fluid from the processing chamber 1000a of the equipment body 1000 through the second fluid delivery pipe 2002 and the water outlet 1000c.

A maintenance hole is provided on the device body 1000, and the maintenance hole is connected to the processing chamber 1000a.
