Description

Technical Field

[0001] This utility model belongs to the field of adsorption tower technology, specifically relating to a multifunctional decolorization adsorption tower. Background Technology

[0002] Adsorption towers are important purification equipment in industrial waste gas and wastewater treatment systems. They use activated carbon or resin filled inside the tower to filter and purify incoming wastewater. Decolorizing adsorption towers can not only filter waste materials but also decolorize wastewater, making them a commonly used multi-functional treatment device in current purification systems. Existing decolorizing adsorption towers mainly consist of a tower body, a filter screen, and a packing layer. The top of the tower body has an inlet, and the bottom of the tower body has an outlet. Wastewater enters the tower body through the inlet and undergoes decolorization and purification through the filter screen and packing layer inside the tower body.

[0003] Existing decolorization adsorption towers can stably purify wastewater during use, but there are still some problems in actual use. Specifically, when the wastewater enters the tower, the overall flow direction is vertically downward and the water surface is relatively stable. This causes highly viscous impurities such as tar in the wastewater to accumulate and adhere to each other, clogging the pores of the filter screen and affecting the overall performance of the adsorption tower. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0006] A multifunctional decolorization adsorption tower includes an adsorption tower body, an upper cylinder assembly, and a lower cylinder assembly. The upper cylinder assembly is installed at the top opening of the adsorption tower body, and the lower cylinder assembly is installed at the bottom opening of the adsorption tower body. The upper cylinder assembly serves as a wastewater inlet and a backwash liquid recovery outlet, while the lower cylinder assembly serves as a wastewater outlet and a backwash liquid inlet. Adjustment components for changing the water flow direction are installed at the connection points between the adsorption tower body and the upper and lower cylinder assemblies.

[0007] As a preferred technical solution of this utility model, the adjustment component includes an outer shell, stirring blades and a drive motor. The outer shell is installed at both the top and bottom of the adsorption tower body, and stirring blades are installed inside the outer shell. A drive motor is provided at the middle of the stirring blades to drive the stirring blades to rotate. The rotation of the stirring blades agitates the liquid inside the adsorption tower body and changes the direction of the water flow.

[0008] As a preferred technical solution of this utility model, the adjustment component further includes guide blocks. Guide blocks are installed at equal intervals on the side wall of the stirring blades, and the liquid enters the adsorption tower body along the gaps between the guide blocks and the gaps between each group of stirring blades.

[0009] As a preferred technical solution of this utility model, the upper cylinder assembly includes an upper shell, a top cover, an exhaust pipe and a wastewater inlet pipe. The upper shell is installed at the top opening of the adsorption tower body, and the top cover is installed on the upper shell. An exhaust pipe for discharging air from the adsorption tower body is installed on one side of the upper surface of the top cover, and a wastewater inlet pipe for wastewater inlet is installed on the other side of the upper surface of the top cover. A flushing liquid outlet pipe is connected to the side wall of the wastewater inlet pipe.

[0010] As a preferred embodiment of the present invention, the upper cylinder assembly further includes a filter screen, and multiple sets of filter screens are installed inside the upper shell, with a quartz layer filling between the filter screens.

[0011] As a preferred technical solution of this utility model, the lower cylinder assembly includes a lower cylinder body, a wastewater discharge pipe and a backwash pipe. The lower cylinder body is installed at the bottom opening of the adsorption tower body. A wastewater discharge pipe is installed on one side of the lower surface of the lower cylinder body, and a backwash pipe is installed on the other side of the lower surface of the lower cylinder body. An airflow injection pipe is connected to the side wall of the backwash pipe.

[0012] As a preferred embodiment of this utility model, control valves are installed at the connection points between the backwash pipe and the airflow injection pipe, and between the wastewater inlet pipe and the flushing liquid outlet pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, by setting an adjustment component, the flow direction of wastewater entering the decolorization adsorption tower is changed. This causes the liquid to be agitated inside the adsorption tower while flowing towards the bottom wastewater discharge pipe, thus disrupting the surface tension of the wastewater. This prevents highly viscous impurities in the wastewater from easily adhering to the filter screen surface and clogging the filter screen. Furthermore, the upper and lower cylinder components not only facilitate the introduction of wastewater for purification and decolorization but also provide reverse flushing inside the decolorization adsorption tower, ensuring the overall working quality of the decolorization adsorption tower.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, this is a schematic diagram of the multifunctional decolorizing adsorption tower in this embodiment. The multifunctional decolorizing adsorption tower in this embodiment can change the flow direction and trajectory of wastewater during its flow, driving the wastewater into the adsorption tower in a vortex manner for purification and decolorization treatment. This disrupts the surface tension of the wastewater, preventing the accumulation of large amounts of viscous impurities that could clog the internal components of the adsorption tower. The multifunctional decolorizing adsorption tower includes an adsorption tower body 1, an upper cylinder assembly 2, and a lower cylinder assembly 3. The adsorption tower body 1 is a tubular structure with openings at the top and bottom, and is filled with resin material. The packing material purifies and decolorizes the wastewater entering the adsorption tower body 1. An upper cylinder assembly 2 is installed at the top opening of the adsorption tower body 1, and a lower cylinder assembly 3 is installed at the bottom opening of the adsorption tower body 1. The upper cylinder assembly 2 is the wastewater inlet, and the lower cylinder assembly 3 is the wastewater outlet. An adjustment assembly 4 is provided at the connection between the adsorption tower body 1 and the upper cylinder assembly 2 and the lower cylinder assembly 3. The adjustment assembly 4 agitates the incoming liquid and changes its flow direction, so that the wastewater enters the adsorption tower body 1 in a vortex manner to be purified and decolorized.

[0025] In this embodiment, the upper cylinder assembly 2 serves not only as a wastewater inlet but also as a return water outlet for subsequent rinsing of the adsorption tower body 1. The lower cylinder assembly 3 serves not only as a wastewater outlet but also as an inlet for rinsing return water.

[0026] As attached Figure 4 As shown, this is a schematic diagram of the adjustment component 4 in this embodiment. The adjustment component 4 includes an outer shell 41, stirring blades 42, and a guide block 43. The outer shell 41 is installed at the connection points between the adsorption tower body 1 and the upper cylinder assembly 2 and the lower cylinder assembly 3. The stirring blades 42, which agitate the liquid and change its flow trajectory, are installed inside the outer shell 41. A drive motor 44, which drives the stirring blades 42 to rotate, is installed at the middle of the outer shell 41. When wastewater enters the adsorption tower body 1 through the upper cylinder assembly 2, the operation of the drive motor 44 drives the stirring blades 42 to rotate within the outer shell 41. At this time, the stirring of the stirring blades 42 causes the liquid inside the adsorption tower body 1 to flow along the inner wall of the adsorption tower body 1, changing its flow trajectory. In terms of flow direction, under the action of the pump body connected to the external pipe of the lower cylinder assembly 3, the liquid inside the adsorption tower body 1 is drawn in, and the liquid is extracted from the inside of the adsorption tower body 1 when the surface tension of the liquid is broken. This avoids the accumulation and adhesion of viscous impurities such as tar in the liquid to the inner wall of the adsorption tower body 1 after the liquid has been left to stand, and assists the adsorption tower body 1 in stable operation. In addition, in this embodiment, guide blocks 43 are installed at equal intervals on the side wall of the stirring blades 42. The setting of the guide blocks 43 allows the liquid to flow out along the gap between each set of stirring blades 42 when the stirring blades 42 are not working and not rotating. This changes the traditional situation where the liquid flows vertically downward under the action of gravity, and assists the adsorption tower body 1 in treating wastewater.

[0027] As attached Figure 5 As shown, this is a schematic diagram of the upper cylinder assembly 2 in this embodiment. The upper cylinder assembly 2 includes an upper shell 21, a top cover 22, and an exhaust pipe 23. The upper shell 21 is installed at the top opening of the adsorption tower body 1. The top cover 22 is provided on the upper shell 21. An exhaust pipe 23 is installed on one side of the upper surface of the top cover 22. The exhaust pipe 23 serves as an exhaust hole for air to be discharged from the adsorption tower body 1. A wastewater inlet pipe 24 is installed on the other side of the upper surface of the top cover 22. Wastewater enters the adsorption tower body 1 through the wastewater inlet pipe 24. A rinsing liquid outlet pipe 25 is connected to the side wall of the wastewater inlet pipe 24. The rinsing liquid outlet pipe 25 serves as a return pipe for subsequent rinsing of the adsorption tower body 1. A multi-layer filter screen 26 is installed inside the upper shell 21. The filter screen 26 filters impurities in the wastewater, and a quartz layer is filled between the filter screens 26.

[0028] As attached Figure 6 As shown, it is a structural schematic diagram of the lower cylinder assembly 3 in this embodiment. The lower cylinder assembly 3 includes a lower cylinder body 31 and a wastewater discharge pipe 32. The lower cylinder body 31 is installed at the bottom opening of the adsorption tower body 1. The wastewater discharge pipe 32 is installed on one side of the lower cylinder body 31. The backwash pipe 33 is installed on the other side of the lower cylinder body 31, and an airflow injection pipe 34 is installed on the side wall of the backwash pipe 33.

[0029] In this embodiment, wastewater enters the adsorption tower body 1 through the wastewater inlet pipe 24. At this time, the flushing liquid outlet pipe 25, wastewater outlet pipe 32, backwash pipe 33, and airflow injection pipe 34 are all in a closed state. As the water level in the adsorption tower body 1 rises, excess air in the adsorption tower body 1 is discharged through the exhaust pipe 23 until the liquid in the adsorption tower body 1 reaches the threshold and the exhaust pipe 23 is closed. At this time, the wastewater is purified and decolorized by the packing material in the adsorption tower body 1. The wastewater outlet pipe 32 is used to discharge the wastewater in the adsorption tower body 1, completing the purification and decolorization of the wastewater. Next, when backwashing the adsorption tower body 1, the backwash pipe 33 inputs the flushing liquid into the adsorption tower body 1 to flush away impurities in the adsorption tower body 1. The flushed liquid is directly discharged through the flushing liquid outlet pipe 25, realizing the backwashing operation in the adsorption tower body 1.

It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
