Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, specifically to an activated carbon regeneration device. Background Technology

[0002] Activated carbon is widely used in water treatment equipment because of its efficient adsorption of pollutants. However, once activated carbon is saturated with pollutants, its adsorption capacity will be greatly reduced, requiring replacement with new activated carbon. To reduce the need for activated carbon replacement in water treatment equipment, physical or chemical methods are used to remove various pollutants adsorbed on the activated carbon from its micropores without damaging its original structure. This allows the activated carbon to regain most of its adsorption capacity and achieve reuse.

[0003] Existing methods for regenerating activated carbon include: heating regeneration, chemical regeneration, biological regeneration, and microwave radiation regeneration. These traditional methods, besides having their own limitations, also share some common drawbacks: 1. Significant loss of activated carbon volume during regeneration; 2. A noticeable decrease in the adsorption capacity of the regenerated activated carbon; 3. The waste gas generated during regeneration causes secondary air pollution. Utility Model Content

[0004] The technical problem to be solved by this utility model is through an activated carbon regeneration device, which has the characteristics of good water purification effect and long service life of activated carbon.

[0005] To solve the above-mentioned technical problems, this utility model provides an activated carbon regeneration device, including a shell with a conical bottom. A filter plate is provided inside the shell, which divides the inner cavity of the shell into an upper chamber and a lower chamber. The filter plate is provided with multiple filter heads. Activated carbon is provided at the bottom of the upper chamber. A positive electrode component and a negative electrode component immersed in the activated carbon are provided at the bottom of the upper chamber. The positive electrode component and the negative electrode component are electrically connected to the positive and negative electrodes of a DC power supply located outside the shell, respectively. A rain shower plate is provided at the top of the upper chamber. An adjustment component for adjusting the horizontal position of the rain shower plate is provided inside the upper chamber. A water inlet is opened at the top of the shell above the rain shower plate, and a water outlet is opened at the bottom of the shell.

[0006] Furthermore, the positive electrode assembly and the negative electrode assembly each include multiple electrodes spaced apart. The multiple electrodes of the positive electrode assembly and the multiple electrodes of the negative electrode assembly are arranged alternately. The electrodes are in the shape of a grid, and the multiple electrodes are connected to each other by a connecting plate. The grid-shaped electrodes have a larger contact area with the activated carbon, resulting in a larger polarization area of ​​the activated carbon.

[0007] Furthermore, the rain shower plate includes an annular sidewall, the bottom end of which is provided with a perforated plate. The top surface of the perforated plate is provided with multiple annular protrusions, each of which is connected to a through hole on the perforated plate. During operation, saline wastewater enters the upper chamber from the inlet and falls into the rain shower plate. The saline wastewater flows into the central through hole of each annular protrusion and then flows through the through hole on the perforated plate to be evenly sprayed down, achieving a rain shower effect. This results in a higher utilization rate of activated carbon and a better water purification effect of the activated carbon regeneration device.

[0008] Furthermore, the adjustment assembly includes four fixed plates distributed at four corners. The fixed plates are located on the inner wall of the housing. Each fixed plate has a threaded hole that runs vertically through it. An adjusting screw is threaded into the threaded hole. A rubber pad is provided on the top of each adjusting screw. The rain shower plate is supported on each rubber pad. Adjusting the adjusting screw can adjust the rain shower plate to a horizontal position, resulting in a better rain shower effect. The rubber pads are used to reduce the vibration noise of the rain shower plate.

[0009] Furthermore, the housing is equipped with a horizontal water inlet pipe located above the rain shower plate. The two ends of the horizontal water inlet pipe are sealed, and the middle part of the horizontal water inlet pipe is connected to the water inlet via a pipeline. Multiple branch pipes are connected to the horizontal water inlet pipe and are spaced apart along the axial direction of the horizontal water inlet pipe. The branch pipes extend away from the water inlet. During operation, saline wastewater first flows into the horizontal water inlet pipe from the water inlet, and then flows out from the multiple branch pipes and falls into the rain shower plate, resulting in a better rain shower effect.

[0010] Furthermore, the outlet is connected to the first port of an electric three-way ball valve via a pipeline, the second port of the electric three-way ball valve is connected to a purified water container via a pipeline (the purified water container is used to store saline purified water), and the third port of the electric three-way ball valve is connected to a backwash water container via a pipeline (the backwash water container is used to store purified water). A water pump is connected in series on the pipeline between the electric three-way ball valve and the backwash water container. A backwash water outlet is provided on the inner side of the top of the upper chamber, and the backwash water outlet is connected to the backwash water container via a pipeline. During backwashing, the saline wastewater is first stopped from entering through the inlet, and the first and third ports of the electric three-way ball valve are connected. The water pump delivers the purified water in the backwash water container to the lower chamber. The purified water in the lower chamber flows through the filter head into the upper chamber. The activated carbon inside the chamber churns under the impact of purified water. The purified water in the upper chamber flows out from the backwash water outlet into the backwash water container. After the activated carbon churns for several minutes, the water pump is turned off. The purified water in the shell flows from the outlet through the electric three-way ball valve and the water pump in sequence, and then enters the backwash water container. After the activated carbon sinks again, those that were originally near the positive electrode component may fall near the negative electrode component, and those that were originally near the negative electrode component may fall near the positive electrode component. This allows the activated carbon to undergo oxidation and reduction reactions in turn, and the sludge it adsorbs is decomposed, precipitated, and desorbed in turn, thereby achieving a better regeneration effect. The cycle of working-backwashing-working is repeated. The activated carbon continuously undergoes oxidation and reduction reactions and is continuously decomposed, reduced, and desorbed. At the same time, saline wastewater is continuously poured in, and saline purified water is continuously discharged.

[0011] The beneficial effects of this invention are as follows: During operation, saline wastewater enters the upper chamber through the inlet and falls into the rain shower plate. The rain shower plate ensures that the saline wastewater is evenly sprayed. Since both the positive and negative electrode components are surrounded by activated carbon, and the saline wastewater has a high conductivity, it becomes the electrolyte after immersing the positive and negative electrode components. When the positive and negative electrode components are energized, the activated carbon around them is polarized due to its excellent conductivity. The activated carbon near the positive electrode component is positive, and the activated carbon near the negative electrode component is negative. An oxidation reaction occurs at the interface between the positive electrode component and the electrolyte. A reduction reaction occurs at the interface between the electrode assembly and the electrolyte. The oxidation reaction dissolves the metals in the electrolyte, while the reduction reaction precipitates the metals. In this process, not only is the saline wastewater electrolyzed, degrading the pollutants it contains, but the polarized activated carbon also participates in the oxidation and reduction reactions. The adsorbed sludge is decomposed, precipitated, and desorbed, and the activated carbon continuously recovers its adsorption capacity. After the electrolyte becomes saline purified water, it flows through the filter head into the lower chamber and then out of the outlet. This novel activated carbon regeneration device features good water purification effect and long service life of activated carbon. Attached Figure Description

The utilization rate of activated carbon is higher, resulting in a better water purification effect of the activated carbon regeneration device.

[0020] Preferably, the adjustment assembly 9 includes four fixed plates 17 arranged at four corners. The fixed plates 17 are disposed on the inner wall of the housing 1. The fixed plates 17 have threaded holes that extend vertically through them. Adjusting screws 18 are threaded into the threaded holes. Rubber pads 19 are provided on the top of the adjusting screws 18. The rain shower plate 8 is supported on each rubber pad 19. Adjusting the adjusting screws 18 can adjust the rain shower plate 8 to a horizontal position, which improves the rain shower effect. The rubber pads 19 are used to reduce the vibration noise of the rain shower plate 8.

[0021] Preferably, the housing 1 is provided with a horizontal inlet pipe 20 located above the rain shower plate 8. The two ends of the horizontal inlet pipe 20 are sealed. The middle part of the horizontal inlet pipe 20 is connected to the water inlet 10 through a pipeline. Multiple water distribution pipes 22 are connected to the horizontal inlet pipe 20 and are spaced apart along the axial direction of the horizontal inlet pipe 20. The water distribution pipes 22 extend in a direction away from the water inlet 10. During operation, saline wastewater first flows into the horizontal inlet pipe 20 from the water inlet 10, and then flows out from the multiple water distribution pipes 22 and falls into the rain shower plate 8, resulting in a better rain shower effect of the rain shower plate 8.

[0022] Preferably, the outlet 11 is connected to the first port 23 of the electric three-way ball valve 12 via a pipeline, the second port 24 of the electric three-way ball valve 12 is connected to the purified water container 25 via a pipeline, the purified water container 25 is used to store saline purified water, the third port 26 of the electric three-way ball valve 12 is connected to the backwash water container 27 via a pipeline, the backwash water container 27 is used to store purified water, a water pump 28 is connected in series on the pipeline between the electric three-way ball valve 12 and the backwash water container 27, and a backwash water outlet 29 is opened on the inner side of the top of the upper chamber 3, the backwash water outlet 29 is connected to the backwash water container 27 via a pipeline; during backwashing, the saline wastewater is first stopped from entering from the inlet 10, the first port 23 and the third port 26 of the electric three-way ball valve 12 are connected, the water pump 28 transports the purified water in the backwash water container 27 to the lower chamber 4, and the purified water in the lower chamber 4 flows through Filter head 5 enters the upper chamber 3. The activated carbon in the upper chamber 3 is agitated by the impact of purified water. The purified water in the upper chamber 3 flows out from the backwash water outlet 29 into the backwash water container 27. After the activated carbon agitates for several minutes, the water pump 28 is turned off. The purified water in the shell 1 flows from the outlet 11 through the electric three-way ball valve 12 and the water pump 28 in sequence, and then enters the backwash water container 27. After the activated carbon sinks again, the activated carbon that was originally near the positive electrode component 6 may fall near the negative electrode component 7, and the activated carbon that was originally near the negative electrode component 7 may fall near the positive electrode component 6.

When the saline wastewater submerges the positive electrode assembly 6 and the negative electrode assembly 7, it becomes the electrolyte. When the positive electrode assembly 6 and the negative electrode assembly 7 are energized, the activated carbon around them is polarized due to its excellent conductivity. The activated carbon near the positive electrode assembly 6 is the positive electrode, and the activated carbon near the negative electrode assembly 7 is the negative electrode.

The oxidation reaction dissolves the metals in the electrolyte, and the reduction reaction precipitates the metals in the electrolyte. In this process, not only is the saline wastewater electrolyzed and the pollutants contained in the saline wastewater degraded, but the polarized activated carbon also participates in the oxidation and reduction reactions. The adsorbed sludge is also decomposed, precipitated, and desorbed. The activated carbon continuously restores its adsorption capacity. After the electrolyte becomes saline purified water, it flows through the filter head 5 into the lower chamber 4 and then flows out from the outlet 11. The activated carbon regeneration device in this embodiment has the characteristics of good water purification effect and long service life of activated carbon.
