[0002] Activated carbon is a specially treated carbon. The organic raw material is heated under air-tight conditions to reduce non-carbon components (this process is called carbonization). Then it reacts with gas, the surface is eroded, and a microporous structure is produced (this process is called activation). Since the activation process is a microscopic process, that is, a large amount of molecular carbide surface erosion is point erosion, resulting in countless tiny pores on the surface of the activated carbon.

[0003] According to the appearance of activated carbon, it is usually divided into two categories: powdered and granular. With the development of modern industry and science and technology, many new varieties of activated carbon have emerged, such as carbon molecular sieve, microsphere carbon, activated carbon nanotubes, activated carbon fiber, etc.

[0004] Activated carbon is an effective adsorbent commonly used in wastewater treatment. However, if saturated activated carbon is discarded, it will not only cause a great waste, but also cause secondary pollution to the environment. Therefore, the regeneration technology of activated carbon should attract the attention of the engineering community. Therefore, it is necessary to design an activated carbon recovery device.

The activated carbon is placed in the cleaning box 3, which will produce bubbles in the water. The detection system divides the number of bubbles into two levels, T1 and T2. T1 means that the activated carbon produces fewer bubbles when it comes into contact with water, and T2 means that the activated carbon produces more bubbles when it comes into contact with water. If the camera component detects that the activated carbon is at level T1, it means that the usage saturation of this batch of activated carbon is high. If the camera component detects that the activated carbon is at level T2, it means that the usage saturation of this batch of activated carbon is low. This detection step is to classify the activated carbon according to the usage saturation, and to predetermine the steps for the subsequent activated carbon regeneration process. The different usage saturations of activated carbon have different regeneration processing steps. The processing steps of activated carbon with low saturation are fewer, and the processing steps of activated carbon with high saturation are more.

[0025] The transport mechanism 1 and the cleaning box 3 are connected together, and the activated carbon particles are placed on the transport mechanism 1 and transported to the cleaning box 3 through the transport mechanism 1.

[0026] An electric-controlled valve 27 is provided at the bottom of the cleaning box 3, and a water filter box 6 is provided on the support frame 2. The top of the water filter box 6 is open and aligned with the electric-controlled valve 27. The electric-controlled valve 27 is controlled by a detection system, which controls the motor 26 to clean the activated carbon. The cleaning time is set to K. When the cleaning time of the cleaning cylinder 5 reaches the value K, the motor 26 pauses and the electric-controlled valve 27 opens. The activated carbon and water in the cleaning box 3 flow into the water filter box 6 along the electric-controlled valve 1. An electric-controlled valve 27 is provided on the side wall of the water filter box 6. A filter 29 is installed on the electric-controlled valve 27. A detachable hose is installed on the electric-controlled valve 27, and the hose is connected to the wastewater tank. The detection system opens the electric-controlled valve 27. Due to the presence of the filter 29, wastewater flows into the wastewater tank along the electric-controlled valve 27 and the hose, while the activated carbon remains in the water filter box 6.

[0027] The interior of the water filter box 6 is low in the middle and high on both sides. A filter screen 29 is set in the low area 28, and the electric control valve 27 is connected to the filter screen 29. The design of the water filter box 6 can speed up the drainage speed and the activated carbon discharge speed, and at the same time, it is more convenient to clean it later.

[0028] A regeneration tank 1 8 and a regeneration tank 2 9 are provided in the support frame 2. The regeneration tank 1 8 is used for a low-temperature heating regeneration process, and the regeneration tank 2 9 is used for a high-temperature heating regeneration process. A discharge valve 1 23 is provided at the outer bottom of the regeneration tank 1 8, and a discharge valve 2 22 is provided at the outer bottom of the regeneration tank 2 9. The detection system controls the regeneration tank 1 8 and the regeneration tank 2 9 to regenerate the activated carbon. When the processing time reaches the discharge valve 1 23 and the discharge valve 2 22, the activated carbon in the regeneration tank is discharged to obtain reusable activated carbon. The regeneration tank 1 8 and the regeneration tank 2 9 are both fixed on the base 24. An electric-controlled valve 3 17 is provided on the top of the regeneration tank 1 8, an extension pipe 1 is provided on the electric-controlled valve 3 17, and an electric-controlled valve 8 19 is provided on the extension pipe 1. An electric-controlled valve 4 16 is provided on the top of the regeneration tank 2 9, and an extension pipe 2 is provided on the electric-controlled valve 4 16, and an electric-controlled valve 5 18 is provided on the extension pipe 2.

[0029] A distribution tank 10 fixed on the support frame 2 is provided above the regeneration tank, and a main discharge pipe 12 and an auxiliary discharge pipe 11 are provided on the top of the distribution tank 10. The diameter of the main discharge pipe 12 is larger than that of the auxiliary discharge pipe 11. The main discharge pipe 12 and the auxiliary discharge pipe 11 are both connected to the water filter box 6 above, and an electric control valve 6 31 is provided at the connection between the main discharge pipe 12 and the water filter box 6, and an electric control valve 7 30 is provided at the connection between the auxiliary discharge pipe 11 and the water filter box 6. The detection system sets the drainage time of the water filter box 6 to L. When the drainage time is reached, the detection system opens the electric control valve 6 31 and the electric control valve 7 30, and the activated carbon is discharged by the electric control valve 6 31 and the electric control valve 7 30. After entering the distribution tank 10, heating wires are evenly laid on the inner wall of the distribution tank 10. The purpose of setting the main discharge pipe 12 and the auxiliary discharge pipe 11 is that the heating wires have been preheated before the main discharge pipe 12 and the auxiliary discharge pipe 11 are opened. At this time, the temperature in the distribution tank 10 is high, and the main discharge pipe 12 and the auxiliary discharge pipe 11 are opened, so that the hot air inside them rises through the main discharge pipe 12 and the auxiliary discharge pipe 11 to preliminarily dry the activated carbon in the water filter box 6, and at the same time dry the area near the main discharge pipe 12 and the auxiliary discharge pipe 11, so that the activated carbon can enter the distribution tank 10 more smoothly. During the heating and drying of the activated carbon, the valves of the main discharge pipe 12 and the auxiliary discharge pipe 11 are often open;

[0030] A pressure-dividing valve 25 is provided on the side wall of the distribution tank 10. The functions of the pressure-dividing valve 25 are to discharge moisture and divide pressure. An air pressure monitor is provided in the distribution tank 10. The air pressure monitor transmits data to the detection system in real time. If the detection system collects air pressure data exceeding the standard, the pressure-dividing valve 25 is opened to release pressure to protect the equipment safety. At the same time, when the distribution tank 10 is not in operation, the pressure-dividing valve 25 can be opened for dehumidification and cleaning.

[0031] A conduit 13 is provided on the side wall of the distribution tank 10, and a conduit 2 14 and a conduit 3 15 are provided on both sides of the conduit 13. The conduit 2 14 is connected to the electric control valve 4 16, and the conduit 3 15 is connected to the electric control valve 3 17. A conduit 4 21 is provided between the distribution tank 10 and the regeneration tank 1 8, and a conduit 5 20 is provided between the distribution tank 10 and the regeneration tank 2 9. A double valve 1 32 is provided on the conduit 5 20, and a double valve 2 33 is provided on the conduit 4 21;

[0032] The detection system sets the heating time to P1 and P2, P1 means short heating time, P2 means long heating time, the heating time for T1 layer activated carbon is P2, and the heating time for T2 layer activated carbon is P1. T1 layer activated carbon has high saturation and many attachments in the activated carbon, so the heating time needs to be more sufficient. T2 layer activated carbon has low saturation and few attachments in the activated carbon, so the heating time of P1 is sufficient. Differentiating the specifications of batch activated carbon and using different heating times can reduce some energy consumption and achieve energy saving and emission reduction effects. According to the detection system, different specifications of batch activated carbon are selected. For the same regeneration tank, if the batch of activated carbon is at the T1 level, the detection system opens the double valve 1 32, and the activated carbon in the distribution tank 10 enters the regeneration tank 2 9 through the conduit 5 20, and the activated carbon is regenerated by high-temperature heating. If the batch of activated carbon is at the T2 level, the detection system opens the double valve 2 33, and the activated carbon in the distribution tank 10 enters the regeneration tank 1 8 through the conduit 4 21, and the activated carbon is regenerated by low-temperature heating. By judging the saturation of the activated carbon and adopting different regeneration processing technologies, it is possible to avoid the situation where all the activated carbon regeneration processes use high-temperature processing, thereby saving the processing cost of the activated carbon.

[0033] When all the activated carbon in the water filter box 6 enters the distribution tank 10, the detection system opens the electric control valve three 17 or the electric control valve four 16, so that the regeneration tank one 8 and the conduit three 15 are connected or the regeneration tank two 9 and the conduit two 14 are connected, and the air flow generated by the high temperature is discharged into the distribution tank 10 through the conduit three 15 or the conduit two 14. Since the temperature in the regeneration tank one 8 and the regeneration tank two 9 is higher than the temperature of the distribution tank 10, the exhaust process is also an insulation process for the distribution tank 10, which is preheated for the next batch of activated carbon drying. At the same time, after the processing of the regeneration tank one 8 and the regeneration tank two 9 is completed, it is necessary to first open the electric control valve five 18 and the electric control valve eight 19 to release the pressure, and then open the discharge valve two 22 and the discharge valve one 23 to ensure the safety of personnel and equipment during equipment operation.
