Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection and relates to an adsorption tower, in particular to an activated carbon adsorption tower. Background Art

[0002] The disposal of domestic waste releases a significant amount of odor. This odor cannot be discharged directly; it must undergo a multi-stage combined treatment process and meet acceptable levels before it can be discharged. This multi-stage combined treatment process involves chemical scrubbing and activated carbon adsorption, both of which must be used in combination to purify the odor. Existing chemical scrubbing typically involves adding sodium hypochlorite to the circulating water, using hypochlorous acid to neutralize certain components of the odor. After chemical scrubbing, the odor passes through a demister to remove the atomized hypochlorous acid mist. After demisting, the odor is then passed to the downstream activated carbon adsorption device.

[0003] After long-term use, we discovered that the demister efficiency of the chemical scrubber cannot reach 100%, causing some water mist to enter the activated carbon adsorption tower. The water mist entering the adsorption tower evaporates, but the sodium hypochlorite in the mist is retained. Over time, the concentration of sodium hypochlorite in the unevaporated water in the adsorption device increases. The adsorption device is made of stainless steel, and the increased Cl- concentration will cause corrosion to the stainless steel. In particular, the adsorption device is made of stainless steel wire mesh on both sides of the bed that holds the activated carbon, which is very susceptible to corrosion. The bottom plate and discharge port of the adsorption device are also severely corroded, causing water dripping from the bottom of the adsorption device, the bed to rupture, and the filler to flow out, thus losing its adsorption and deodorization function. Summary of the Invention

[0004] The purpose of this utility model is to solve the above problems existing in the prior art and propose an activated carbon adsorption tower, which solves the technical problem of how to increase the service life of the existing activated carbon adsorption tower.

[0005] The purpose of this utility model can be achieved through the following technical solutions:

[0006] An activated carbon adsorption tower comprises a tower shell with an inlet and an outlet on the side, and is characterized in that a plurality of stainless steel frames arranged in parallel are fixed inside the tower shell, and an adsorption material bed is formed between adjacent stainless steel frames. An adsorption material filler delivery port is provided at the top of the tower shell corresponding to each adsorption material bed, and an adsorption material discharge port is provided at the bottom of the tower shell corresponding to each adsorption material bed, and a detachable corrosion-resistant bottom plate is provided at the adsorption material discharge port.

[0007] The activated carbon adsorption tower of the present application includes a tower shell, and the interior of the tower shell has an adsorption material bed separated by a stainless steel frame. The adsorption material bed can accommodate adsorption material (such as activated carbon and other materials), so that the adsorption material is evenly spaced into layers in the tower shell. An adsorption material filler delivery port corresponding to each layer of the adsorption material bed is provided on the top of the tower shell. The adsorption material can be filled and delivered at the adsorption material filler delivery port, which is very convenient. Moreover, each layer of the adsorption material bed has an adsorption material filler delivery port corresponding to the adsorption material bed. The adsorption material filler delivery port can be more conducive to air circulation inside the tower shell, allowing water vapor to evaporate. To be more precise, it is more conducive to the volatilization of water vapor of the adsorption material in the adsorption material bed, thereby reducing corrosion and increasing the service life of the adsorption tower.

[0008] The bottom of the tower shell of the present application is provided with a corrosion-resistant bottom plate, which is more corrosion-resistant when water accumulates and extends the service life of the tower shell.

[0009] The tower shell of the present application is provided with an adsorption material discharge port at the bottom, and the adsorption material filler is placed in the adsorption material discharge port and arranged up and down, which can be more conducive to the replacement of the adsorption material filler, and the accumulated water accumulated in the tower shell can be well discharged from the bottom of the tower shell during the discharge process, avoiding accumulation, so that the discharge port position and the bottom plate position are greatly reduced. The time of being corroded by acid liquid, thereby increasing the service life of the overall adsorption tower.

[0010] In the above-mentioned activated carbon adsorption tower, a material retaining structure is fixed on one side of the stainless steel frame where the adsorption material bed is located, and the material retaining structure is made of corrosion-resistant material.

[0011] The inner liner of the adsorption tower of the present application is filled with a stainless steel frame, which can have a good anti-corrosion effect. In addition, a material blocking structure is provided between the stainless steel frame and the adsorption material of the present application. The material blocking structure can block the adsorption material to prevent the adsorption material from entering the interior of the stainless steel frame, and can block the adsorption material in the adsorption material bed to form an interval adsorption position. In this way, the stainless steel frame is more transparent and more conducive to air circulation to take away water vapor; secondly, the material blocking structure can isolate the adsorption material from direct contact with the stainless steel frame, avoid corrosion and rust caused by the side of the stainless steel frame contacting the adsorption material, and can better improve the service life of the adsorption tower.

[0012] In the above-mentioned activated carbon adsorption tower, the material retaining structure includes a wire mesh made of PP material, and the wire mesh covers the side of the stainless steel frame.

[0013] This retaining structure is made of PP material, which will not be corroded by acid and has good durability. In addition, this retaining structure is also a wire mesh, which can greatly improve the overall durability without affecting ventilation and air permeability.

[0014] In the above-mentioned activated carbon adsorption tower, the material retaining structure further includes a grid, which is located between the wire mesh and the stainless steel frame for supporting the wire mesh, and the surface of the grid is covered with a coating made of fiberglass reinforced plastic material.

[0015] The material retaining structure of the present application also includes a grille, which is located between the wire mesh and the stainless steel frame and can support the wire mesh. Because the wire mesh is soft and the hollow area of ​​the stainless steel frame is large, the wire mesh is easily deformed and broken when pressed against by the adsorbed material, so a grille is added for support. The surface of the grille itself has a fiberglass coating that can isolate water vapor and can also prevent the stainless steel frame from contacting the adsorbed material, thereby further improving the overall structural strength and service life.

[0016] In the above-mentioned activated carbon adsorption tower, the material retaining structure includes a perforated plate made of plastic material, and the perforated plate is pressed against the side of the stainless steel frame to form a support.

[0017] This is the second embodiment of the material blocking structure of the present application. In this embodiment, the material blocking structure is a perforated plate. The perforated plate can both block the adsorption material and support the adsorption material. The perforated plate itself is made of plastic material with good stability and will not be corroded. This design can achieve the same technical effect as the above-mentioned solution.

[0018] In the above-mentioned activated carbon adsorption tower, the corrosion-resistant bottom plate is laid at the bottom of the inner cavity of the tower shell, and the corrosion-resistant bottom plate forms a corrosion-resistant supporting bottom surface at each adsorption material bed layer. The adsorption material discharge port is located below the corrosion-resistant bottom plate, and the adsorption material discharge port is opened by disassembling the corrosion-resistant bottom plate.

[0019] The corrosion-resistant bottom plate of the present application is directly laid on the bottom of the tower shell, and part of the area of ​​the corrosion-resistant bottom plate forms the corrosion-resistant supporting bottom surface at the bottom of the adsorption material bed. In this way, even if water vapor drips from the adsorption material bed, it can fall on the corrosion-resistant bottom plate and be isolated by the corrosion-resistant bottom plate. This can prevent the bottom of the tower shell from being corroded and further improve the overall service life.

[0020] In the above-mentioned activated carbon adsorption tower, the surface of the corrosion-resistant bottom plate and the surface of the bottom of the tower shell are both covered with a coating made of glass fiber reinforced plastic material.

[0021] The tower shell of the present application is covered with a fiberglass coating at the bottom, and the surface of the corrosion-resistant base plate is also provided with a fiberglass coating. The fiberglass coating can effectively further isolate water vapor and further improve the service life.

[0022] In the above-mentioned activated carbon adsorption tower, the stainless steel skeleton is constructed by using square tubes, and each stainless steel skeleton has a sheet-like structure and has evenly distributed hollow cavities thereon.

[0023] The stainless steel frame of this application is constructed by welding square tubes, which is convenient for production. The overall hollow shape of the frame is characterized by multiple hollow cavities that facilitate air circulation and prevent water accumulation, thereby extending the service life. In addition, the overall stainless steel frame is divided into multiple sheet structures, so that any corrosion can be replaced separately, facilitating maintenance and further extending the service life.

[0024] In the above-mentioned activated carbon adsorption tower, the inlet and the outlet are respectively located on two opposite sides of the tower shell, and all the stainless steel frames are arranged side by side inside the tower shell between the inlet and the outlet.

[0025] The relative design of the inlet and outlet allows smoother air circulation, and the stainless steel frame is located between the outlet and the inlet, allowing sufficient contact between the adsorption material and the air between the stainless steel frames, and also fully utilizing the transparent performance of the hollow stainless steel frame to further improve the overall service life.

[0026] In the above-mentioned activated carbon adsorption tower, there are multiple adsorption material filling inlets and adsorption material unloading ports corresponding to each adsorption material bed layer. The multiple adsorption material filling inlets and adsorption material unloading ports are arranged at intervals along the length direction of the tower shell, and each adsorption material filling inlet has a corresponding adsorption material unloading port.

[0027] The adsorption material filling port and the adsorption material discharge port of the present application are both opened corresponding to the adsorption material bed layer and the two are opened correspondingly. This design can increase the permeability when cleaning the adsorption material, so that there are no dead corners in the entire tower shell, which can be better ventilated and cleaned, and further improve the overall service life.

[0028] Compared with existing technologies, the advantages of this product are:

[0029] 1. The adsorption materials are evenly spaced into layers inside the tower shell. Each layer of the adsorption material bed has an adsorption material filler delivery port. The adsorption material filler delivery port can be more conducive to the air circulation inside the tower shell, allowing water vapor to evaporate. To be more precise, it is more conducive to the volatilization of water vapor in the adsorption material bed, thereby reducing corrosion and increasing the service life of the adsorption tower.

The connection between the cover plate and the tower shell 1 can be a bolt connection. The bolts are unscrewed when it is needed to add material and reinstalled after the addition is completed. Of course, there can also be other more convenient connection methods, such as a hinged, superimposed, locking and snap-fitting structure. Many of these connection methods will not be elaborated on here. The bottom of the tower shell 1 is provided with an adsorption material discharge port 14 corresponding to each adsorption material bed 3, and a detachable corrosion-resistant bottom plate 4 is provided at the adsorption material discharge port 14. The activated carbon adsorption tower of the present application includes a tower shell 1, and the interior of the tower shell 1 has an adsorption material bed 3 separated by a stainless steel frame 2. The adsorption material bed 3 can accommodate adsorption materials such as activated carbon, so that the adsorption materials are evenly spaced into layers in the tower shell 1. The top of the tower shell 1 is provided with an adsorption material filler delivery port 13 corresponding to each layer of the adsorption material bed 3. The adsorption material can be filled and delivered at the adsorption material filler delivery port 13, which is very convenient. In addition, each layer of the adsorption material bed 3 has an adsorption material filler delivery port 13. The adsorption material filler delivery port 13 can be more conducive to the air circulation inside the tower shell 1, allowing water vapor to evaporate. To be more precise, it is more conducive to the volatilization of adsorption material water vapor in the adsorption material bed 3, thereby reducing corrosion and thus increasing the service life of the adsorption tower. The bottom of the tower shell 1 of the present application is provided with a corrosion-resistant bottom plate. Such a design can be more corrosion-resistant when water accumulates, thereby extending the service life of the tower shell 1. The tower shell 1 of the present application is provided with an adsorption material discharge port 14 at the bottom, and the adsorption material filler feeding port 13 and the adsorption material discharge port 14 are arranged up and down, which can be more conducive to the replacement of the adsorption material filler, and the accumulated water accumulated in the tower shell 1 can be well discharged from the bottom of the tower shell 1 during the discharge process, avoiding siltation, so that the discharge port position and the bottom plate position are greatly reduced.

The material blocking structure 5 can block the adsorption material to prevent the adsorption material from entering the interior of the stainless steel frame 2, and can block the adsorption material at the adsorption material bed 3 to form an interval adsorption position, so that the stainless steel frame 2 is more transparent and more conducive to air circulation to take away water vapor; secondly, the material blocking structure 5 can isolate the adsorption material from direct contact with the stainless steel frame 2, avoid corrosion and rust caused by the side of the stainless steel frame 2 contacting the adsorption material, and can better improve the service life of the adsorption tower.

[0039] Furthermore, the retaining structure 5 includes a wire mesh 51 made of PP material, which covers the side of the stainless steel frame 2. The retaining structure 5 is made of PP material, which is not corroded by acid and has good durability. In addition, the retaining structure 5 is made of wire mesh 51, which can greatly improve the overall durability without affecting ventilation.

[0040] Furthermore, the retaining structure 5 also includes a grille 52, which is located between the wire mesh 51 and the stainless steel frame 2 and is used to support the wire mesh 51. The surface of the grille 52 is covered with a coating made of fiberglass. The retaining structure 5 of the present application also includes a grille 52, which is located between the wire mesh 51 and the stainless steel frame 2 and can support the wire mesh 51. Because the wire mesh 51 is soft and the stainless steel frame 2 has a large hollow area, the wire mesh 51 is easily deformed and broken when pressed against by the adsorbent material. Therefore, the grille 52 is added for support. The fiberglass coating on the surface of the grille 52 can isolate water vapor and further prevent the stainless steel frame 2 from contacting the adsorbent material, thereby further improving the overall structural strength and service life.

[0041] Furthermore, the corrosion-resistant bottom plate 4 is laid on the bottom of the inner cavity of the tower shell 1, and the corrosion-resistant bottom plate 4 forms a corrosion-resistant supporting bottom surface 41 at each adsorption material bed 3. The adsorption material discharge port 14 is located below the corrosion-resistant bottom plate 4, and the adsorption material discharge port 14 is opened by removing the corrosion-resistant bottom plate 4. The corrosion-resistant bottom plate 4 of the present application is laid directly on the bottom of the tower shell 1, and a part of the corrosion-resistant bottom plate 4 forms the corrosion-resistant supporting bottom surface 41 at the bottom of the adsorption material bed 3. In this way, even if water vapor drips from the adsorption material bed 3, it can fall on the corrosion-resistant bottom plate 4 and be isolated by the corrosion-resistant bottom plate 4. This can prevent the bottom of the tower shell 1 from being corroded, further improving the overall service life.

[0042] Furthermore, the surface of the corrosion-resistant bottom plate 4 and the bottom surface of the tower shell 1 are both covered with a coating made of fiberglass. The tower shell 1 of the present application is covered with a fiberglass coating at the bottom, and the surface of the corrosion-resistant bottom plate 4 also has a fiberglass coating. The fiberglass coating can effectively further isolate water vapor and further improve the service life.

[0043] Furthermore, the stainless steel skeleton 2 is constructed using square tubes. Each section of the stainless steel skeleton 2 has a sheet-like structure and is provided with evenly distributed hollow cavities 21. The stainless steel skeleton 2 of the present application is constructed using square tubes and welded together, which facilitates production and creates a hollowed-out structure. The multiple hollow cavities 21 facilitate air circulation and prevent water accumulation, thereby extending service life. Furthermore, the overall stainless steel skeleton 2 is divided into multiple sheet-like structures, allowing individual replacements if corrosion occurs, facilitating maintenance and further extending service life.

[0044] Furthermore, the inlet 11 and outlet 12 are located on opposite sides of the tower shell 1, and all the stainless steel frames 2 are arranged side by side inside the tower shell 1 between the inlet 11 and the outlet 12. The relative design of the inlet 11 and the outlet 12 allows for smoother air circulation, and the stainless steel frames 2 are located between the outlet 12 and the inlet 11, allowing sufficient contact between the adsorption material and the air between the stainless steel frames 2, and also fully utilizing the transparent performance of the hollow stainless steel frames 2, further improving the overall service life.
