[0002] With the rapid development of my country's economy, a large amount of sewage is generated both in daily life and in industrial parks around cities. Currently, a large amount of activated coke is used in the treatment of sewage, especially industrial sewage. However, the activated coke becomes saturated during the adsorption process. At this time, the activated coke needs to be regenerated or replaced to ensure the filtering effect of the sewage.
[0003] However, existing technologies often remove saturated activated coke and then transport it to a coke washer for regeneration, which significantly reduces the regeneration rate of the activated coke. Furthermore, removing the activated coke also affects wastewater treatment efficiency. Automatic coke washing is particularly important for adsorption filters with large areas.

[0029] The present invention is further described in detail below in conjunction with preferred embodiments. More details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.
[0030] The accompanying drawings are schematic diagrams of embodiments of the present invention. It should be noted that the drawings are merely examples and are not drawn to scale, and should not be used to limit the actual scope of protection claimed in the present invention.
[0031] A movable coke washing system is used for automatic cleaning of activated coke in adsorption filtration tanks for large-area water purification, thereby improving water purification efficiency and ensuring water quality.
[0032] As shown in FIG1 , a movable coke washing system includes a saturated activated coke discharge mechanism, a regenerated activated coke feeding mechanism, a coke washing mechanism, a water body monitoring mechanism 300, and a control mechanism. The control mechanism is respectively connected to the saturated activated coke discharge mechanism, the regenerated activated coke feeding mechanism, the coke washing mechanism, and the water body monitoring mechanism 300 to realize automatic cleaning and regeneration of the activated coke in the adsorption filtration tank.
[0033] The activated coke discharge mechanism is used to discharge saturated activated coke from the adsorption filter tank and transfer it to the coke washing mechanism, which cleans and regenerates the saturated activated coke to produce regenerated activated coke. The regenerated activated coke addition mechanism adds the regenerated activated coke to the adsorption filter tank that discharges saturated activated coke, causing the adsorption filter tank to perform adsorption filtration on wastewater entering the adsorption filter tank. The water monitoring mechanism 300, located at the outlet of the adsorption filter tank, monitors the regenerated water obtained after treatment in the adsorption filter tank, obtains regenerated water data, and transmits the real-time monitoring data to the control mechanism. Based on the regenerated water data, the control mechanism predicts the cleaning of the activated coke and / or plans a route, thereby achieving automatic cleaning and regeneration of the activated coke.
[0034] The activated coke in the adsorption filtration tank can be positioned on either a cross-section or a longitudinal section within the adsorption filtration tank, without specific limitation. It should be noted that it is necessary to ensure that all wastewater passes through the activated coke in the adsorption filtration tank to achieve adsorption purification of the wastewater by the activated coke.
[0035] The activated coke is preferably activated coke particles.
[0036] The activated coke discharge mechanism includes a frame removal device, an activated coke protection frame 101, and an output pipe. The frame removal device assists in removing the activated coke protection frame 101 from the adsorption filtration tank. The activated coke protection frame 101 is used to hold the activated coke. The output pipe is used to direct the activated coke within the protection frame to the coke washing mechanism. The activated coke protection frame 101 is placed in the adsorption filtration tank. When the activated coke is placed in the activated coke protection frame 101, it prevents the activated coke from floating during the water purification process, which could affect the water purification effect.
[0037] The frame removal device is connected to the active coke protection frame 101 and may be a lifting device. When the control device issues an active coke cleaning command, the frame removal device removes the active coke protection frame 101 from the adsorption filtration pool.
[0038] The size of the activated coke protection frame 101 is consistent with the size of the water flow direction of the adsorption filtration pool in the flow direction of water filtration, thereby ensuring that all sewage flows out after being adsorbed and filtered by the activated coke.
[0039] Specifically, the length and width of the end of the activated coke protection frame 101 near the bottom of the filter tank are equal to the length and width of the bottom of the filter tank to ensure that all sewage passes through the activated coke. In this case, the sewage enters the adsorption filter tank from the bottom and overflows the adsorption filter tank after passing through the activated coke. Alternatively, the activated coke protection frame 101 vertically divides the adsorption filter tank into two spaces, that is, the length and width of the side of the activated coke protection frame 101 that is perpendicular to the bottom and side of the adsorption filter tank contacts the inner wall of the adsorption filter tank. In this case, the sewage enters the adsorption filter tank from one side of the activated coke protection frame 101 and overflows from the adsorption filter tank on the other side of the activated coke protection frame 101 after passing through the activated coke.
[0040] Here, the active coke protection frame 101 is laid in the adsorption filtration tank as an example for detailed description:
[0041] As shown in Figure 2, the adsorption filtration tank is provided with an inlet area 10 and a drain area 20, with the inlet area 10 positioned lower than the drain area 20. Each adsorption filtration tank can be provided with multiple inlet areas 10 and multiple drain areas 20, with each inlet area 10 corresponding to a drain area 20. Recycled water from the multiple drain areas 20 is collected in a water storage area 30, which is then recycled based on water demand. The water storage area 30 is located at the end of the drain area 20 away from the inlet area 10, and the side surface of the drain area 20 at this end of the water storage area 30 is positioned lower than the side surface of the drain area 20 away from the end of the water storage area 30, thereby allowing purified water from the drain area 20 to overflow into the water storage area 30.
[0042] The water inlet area 10 is arranged below the level of the corresponding drainage area 20, and each water inlet area 10 is provided with an active coke protection frame 101. Each drainage area 20 is provided with a water monitoring mechanism 300 and a pumping device at one end close to the water storage area 30. The water monitoring mechanism 300 is arranged on the outer wall edge of the drainage area 20 close to the water storage area 30 and away from the bearing surface, that is, the water monitoring mechanism 300 is arranged at the overflow outlet of the drainage area 20. The pumping device is arranged on the inner wall of the bottom surface of the drainage area 20 close to the water storage area 30 and close to the bearing surface, that is, to ensure the discharge of recycled water in the drainage area 20.
[0043] The pumping device may be a pump or other device that can discharge the recycled water in the drainage area 20, and no specific limitation is made here.
[0044] The active coke protection frame 101 is disposed at one end of the water inlet area 10 adjacent to the drainage area 20. The maximum cross-section of the active coke protection frame 101 is the same as the cross-section of the water inlet area 10. The water inlet area 10 is provided with a sewage inlet 10-1, which can be disposed at any position below the horizontal position of the drainage area 20.
[0045] As shown in Figure 3, the activated coke protection frame 101 includes a first loading area 104 and a second loading area 105. The first loading area 104 is positioned above the second loading area 105. When the activated coke protection frame 101 is placed in the adsorption filtration tank, the first loading area 104 is located away from the sewage inlet 10-1, that is, the first loading area 104 is adjacent to the drainage area 20. A feed port 102 is provided at one end of the first loading area 104 away from the second loading area 105. After the activated coke is cleaned, it enters the activated coke protection frame 101 through the feed port 102. A discharge port 103 is provided at one end of the second loading area 105 away from the first loading area 104. When the activated coke in the activated coke protection frame 101 needs to be cleaned, it is discharged from the activated coke protection frame 101 through the discharge port 103 and enters the coke washing mechanism.
[0046] The shape and size of the first loading area 104 in a horizontal plane are equal to the shape and size of the inner wall of the active coke protection frame 101 in the water inlet area 10, so that the active coke protection frame 101 covers the entire cross-section of the water inlet area 10 through which water passes. The second loading area 105 is preferably funnel-shaped. The shape and size of the end of the second loading area 105 connected to the first loading area 104 match the shape and size of the first loading area 104. The shape of the end of the second loading area 105 away from the first loading area 104 matches the shape of the first loading area 104 and is smaller in size than the first loading area 104. The end of the discharge port 103 connected to the second load-bearing area 105 is on the same horizontal line as the end of the second load-bearing area 105 away from the first load-bearing area 104, and the discharge port 103 is inclined toward the end away from the first load-bearing area 104 to ensure the discharge of the active coke in the active coke protection frame 101, that is, in the vertical direction, the lowest position of the discharge port 103 is on the same horizontal plane as the position connected to the second load-bearing area 105, and there is a downward angle between the discharge port 103 and the horizontal plane.
[0047] The feed port 102 and the discharge port 103 are respectively provided with opening and closing doors, and when the opening and closing doors are opened, the activated coke is added or discharged. The feed port 102 is connected to one end of the output pipe.
[0048] A mobile coke-washing system may include one or more coke-washing mechanisms. A control mechanism controls the coke-washing mechanisms to reach designated positions based on cleaning commands, thereby cleaning the active coke in different water inlet areas 10. The coke-washing mechanisms include a travel unit and a cleaning unit, which is mounted on the travel unit. The travel unit enables movement of the coke-washing mechanisms, while the cleaning unit cleans the active coke.
[0049] The walking unit includes a supporting platform, walking wheels, a driving device, and a braking device. The walking wheels are mounted on the side of the supporting platform; the driving device is connected to the walking wheels to provide walking power for the walking wheels; the braking device is adjacent to the walking wheels and is used to fix the walking unit in a specified position, thereby fixing the cleaning unit.
[0050] The cleaning unit includes a cleaning barrel, which is provided with a cleaning feed port and a cleaning discharge port. The cleaning feed port is connected to an end of the output pipe away from the feed port 102 of the activated coke protection frame 101.
[0051] The number of the regenerated active coke feeding mechanisms is the same as the number of the coke washing mechanisms, and each coke washing mechanism corresponds to one regenerated active coke feeding mechanism.
[0052] The regenerated activated coke feeding mechanism includes an activated coke storage unit and a traveling unit. The activated coke storage unit is used to store cleaned regenerated activated coke, and the traveling unit places the activated coke storage unit in a designated position to feed activated coke or receive regenerated activated coke. The activated coke storage unit is fixed to the traveling unit.
[0053] The activated coke storage unit includes a regenerated coke feed inlet and a regenerated coke discharge outlet, both of which are controllably openable and closable. When the activated coke storage unit receives regenerated activated coke, the regenerated coke feed inlet is connected to the cleaning discharge outlet via an output pipe. When the activated coke storage unit adds regenerated activated coke to the activated coke protection frame 101, the regenerated coke discharge outlet is connected to the feed inlet 102 of the activated coke protection frame 101 via an output pipe.
[0054] The control mechanism includes a communication unit, an analysis unit, a storage unit, an input unit, and a display unit. The communication unit is used to receive monitoring data from the water monitoring mechanism 300 and send control commands to the activated coke discharge mechanism, the regenerated activated coke feeding mechanism, and the coke washing mechanism. The analysis unit is used to pre-judge the cleaning of the activated coke in the water inlet area 10, achieve timely cleaning of the activated coke in the target water inlet area 10, and plan the coke washing route and the coke replacement time of the activated coke protection frame 101 in the target water inlet area 10 based on the location of the coke washing mechanism. The storage unit is used to store preset data and store the work logs of the activated coke discharge mechanism, the regenerated activated coke feeding mechanism, the coke washing mechanism, and the water monitoring mechanism 300. The input unit can input different control commands and input / modify preset data. The display unit is used to display the activated coke cleaning status predicted by the analysis unit.
[0055] When activated coke cleaning is required, the control mechanism controls the sewage inlet 10-1 to stop water intake and starts the pumping device 20-1 to discharge the purified water in the drainage area 20 into the water storage area 30 to prevent the purified water from mixing with the sewage that has not passed through the activated coke, thereby affecting the water quality of the purified water.
[0056] When all the purified water in the drainage area 20 is discharged into the water storage area 30 , the control mechanism reads the coordinates of the target active coke protection frame 101 and obtains the coordinates of the first preset position, the second preset position and the third preset position connected to the coordinates.
[0057] The control mechanism controls the frame removal device to remove the target active coke protection frame 101 to the corresponding first preset position based on the coordinates of the target active coke protection frame 101. Simultaneously, the control mechanism controls the target coke washing mechanism to move to the second preset position corresponding to the first preset position of the target active coke protection frame 101. The control mechanism then connects the discharge port 103 of the active coke protection frame 101 to the feed port of the washing bucket via an output pipe. The discharge port 103 is then opened, and the activated coke in the active coke protection frame 101 is added to the washing bucket, which then washes the activated coke.
[0058] The control mechanism determines whether all the purified water in the drainage area 20 is discharged into the water storage area 30 based on the working time of the pumping device 20-1. Specifically, when the working time of the pumping device 20-1 reaches the first time threshold, the control mechanism determines that all the purified water in the drainage area 20 is discharged into the water storage area 30.
[0059] Each drainage area 20 of the adsorption filtration tank corresponds to a first preset position, which is the position where the active coke protection frame 101 in each drainage area 20 is suspended after being taken out during the coke washing and discharge operation.
[0060] The second preset position refers to the optimal position for the coke washing mechanism to discharge the active coke in the active coke protection frame 101 in each drainage area 20 of the adsorption filtration pool when the active coke protection frame 101 performs the coke washing and coke discharge operation.
[0061] The third preset position refers to the position of the regenerated activated coke feeding mechanism corresponding to the water inlet area 10 where the target activated coke protection frame 101 is located when the activated coke protection frame 101 in each drainage area 20 in the adsorption filtration pool performs the regenerated coke feeding operation.
[0062] The control mechanism has a preset coke cleaning map in its storage unit. The map includes the first, second, and third preset positions corresponding to the active coke protection frame 101 in each drainage area 20. The map can be input or modified via the input device.
[0063] The first time threshold is the quotient of the capacity of the drainage area 20 and the working efficiency of the pumping device 20-1. The first time threshold can be input or modified through the input unit, or it can be calculated by the control mechanism based on the capacity of the drainage area 20 and the working efficiency of the pumping device 20-1 and stored in the storage unit. No specific restrictions are made here.
[0064] The coke drainage map is a three-dimensional map with coordinates including the x-axis, y-axis, and z-axis. The plane formed by the x-axis and y-axis represents the horizontal plane, and the z-axis represents the vertical height relative to the horizontal plane. The coke drainage map displays the coordinates (x1, y1, z1), (x2, y2, z2), ... (xn, yn, zn) of the active coke protection frames 101 in each drainage area 20, where n is the number of active coke protection frames 101, i.e., the number of inlet areas 10 included in the adsorption filtration tank.
[0065] The coke washing map includes a first layer and a second layer. The first layer is a three-dimensional realistic or proportional image of the adsorption filtration pool, and the second layer is a coordinate map, which is overlaid on the first layer. In the second layer, the coordinates of the location of the active coke protection frame 101 in each drainage area 20 of the adsorption filtration pool are marked corresponding to the location of the active coke protection frame 101 in the drainage area 20 in the first layer. The coordinates of the location of the active coke protection frame 101 in each drainage area 20 are connected to the coordinates of the first preset position, second preset position, and third preset position corresponding to the active coke protection frame 101. The coordinates of the first preset position, second preset position, and third preset position corresponding to the active coke protection frame 101 are marked on the second layer corresponding to the corresponding position in the first layer.
[0066] The defocus map sets the map into two independent and related layers, which not only ensures the intuitive viewing effect of each position, but also enables the target preset position to be quickly obtained in the defocus map.
[0067] When the activated coke within the activated coke protection frame 101 is completely discharged, the control mechanism controls the frame removal device to return the target activated coke protection frame 101 to the original water inlet area 10 (original coordinates). The frame removal device may include a quality monitoring device. The control mechanism receives quality data acquired by the quality monitoring device in real time. When the difference between the quality of the activated coke protection frame 101 before and after discharge is greater than or equal to a first quality threshold, the control mechanism determines that the activated coke within the activated coke protection frame 101 is completely discharged. The first quality threshold is a preset value that can be entered or modified via the input device.
[0068] After the frame removal device returns the target activated coke protection frame 101 to the original water inlet area 10 (original coordinates), the control mechanism controls the travel unit of the regenerated activated coke feeding mechanism to place the activated coke storage unit at a third preset position corresponding to the water inlet area 10 where the target activated coke protection frame 101 is located. The regenerated coke discharge port of the activated coke storage unit is connected to the feed port 102 of the target activated coke protection frame 101 via an output pipe. The regenerated coke discharge port is then opened to allow the regenerated activated coke from the activated coke storage unit to be added to the target activated coke protection frame 101, thereby cleaning and regenerating the activated coke within the target activated coke protection frame 101. The activated coke stored in the activated coke storage unit constitutes a portion of the activated coke required for the activated coke protection frame 101.
[0069] In the entire movable coke washing system, the amount of activated coke required for one activated coke protection frame 101 is one portion. The entire movable coke washing system includes at least portions of activated coke equal to the sum of the number of activated coke protection frames 101 and the number of cleaning mechanisms. Therefore, after the activated coke that needs to be cleaned and regenerated in the activated coke protection frame 101 is discharged, the regenerated activated coke that has been cleaned can be added, thereby improving the water purification efficiency of the adsorption filter tank.
[0070] A movable coke washing system is described below with reference to a preferred embodiment.
[0071] The coke washing mechanism is provided with one, and at this time, the active coke in different water inlet areas 10 of the adsorption filter tank are all cleaned by the coke washing mechanism, thereby ensuring the purification effect of the adsorption filter tank.
[0072] However, when the activated coke in different water inlet areas 10 all need to be cleaned, the activated coke in the water inlet area 10 that needs to be cleaned later needs to wait until the activated coke in the water inlet area 10 that needs to be cleaned earlier is cleaned before the activated coke can be cleaned. During this waiting time, in order to ensure the water quality of the recycled water, it is necessary to close the sewage inlet 10-1 of the water inlet area 10 that needs to be cleaned later, and stop the water purification operation of the water inlet area 10 that needs to be cleaned later, thereby reducing the water purification efficiency.
[0073] In order to solve the above problems, the analysis unit of the control mechanism performs activated coke cleaning planning based on the recycled water data detected by the water body detection mechanism installed in the drainage area 20 corresponding to each water inlet area 10 of the current adsorption filter tank, thereby ensuring that at least n-1 water inlet areas 10 are carrying out sewage purification, thereby making the sewage purification efficiency of the adsorption filter tank the highest.
[0074] The storage unit of the control mechanism stores an active coke cleaning remaining time estimation table. The information in the active coke cleaning remaining time estimation table can be input or modified through the input unit, or can be updated based on the maximum active coke cleaning waiting time corresponding to the recycled water data detected by the water body detection mechanism.
[0075] The activated coke cleaning remaining time estimation table includes different recycled water data and the maximum activated coke cleaning waiting time corresponding to the different recycled water data.
[0076] Here, the water body monitoring mechanism 300 is taken as a water flow velocity monitoring device as an example for explanation.
[0077] The water flow rate monitoring device monitors the flow rate of regenerated water flowing from the drainage area 20 to the water storage area 30 to obtain water flow data, which is the regenerated water data. The activated coke cleaning remaining time estimation table includes different regenerated water flow rate segments and the maximum activated coke cleaning waiting times corresponding to each regenerated water flow rate segment.
[0078] The calculation unit of the control mechanism predicts the cleaning time required for the activated coke in each water inlet area 10 of the adsorption filter tank based on the regenerated water flow rate in the water flow data detected by the water flow rate monitoring device installed in each water inlet area 10 corresponding to the drainage area 20 of the current adsorption filter tank, and plans the cleaning of the activated coke in each water inlet area 10 of the adsorption filter tank, so as to ensure that the adsorption filter tank maintains the maximum purification efficiency.
[0079] The communication unit of the control mechanism receives in real time the water flow data detected by the water flow rate monitoring device installed in the drainage area 20 corresponding to each water inlet area 10, and the analysis unit determines the specific regenerated water flow rate segment in the activated coke cleaning remaining time estimation table to which the regenerated water flow rate in the current water flow data belongs, and determines / adjusts the maximum waiting time for activated coke cleaning in each water inlet area 10 based on the regenerated water flow rate segment and the maximum waiting time for activated coke cleaning corresponding to the current water flow data.
[0080] The calculation unit sorts the maximum waiting time for cleaning the 10 active coke units in each water inlet area, calculates the maximum waiting time for cleaning the 10 active coke units in two adjacent water inlet areas, and obtains the maximum waiting time difference for cleaning the 10 active coke units in each of the two adjacent water inlet areas. The maximum waiting time difference for cleaning the 10 active coke units in each of the two adjacent water inlet areas is referred to as the waiting time difference. The calculation unit then subtracts the obtained waiting time difference from the second time duration to obtain the cleaning interval duration. The calculation unit then determines / adjusts the maximum waiting time for cleaning the 10 active coke units in each water inlet area based on the relationship between the cleaning interval duration and the second time duration threshold.
[0081] The storage unit stores the time required for the coke washing operation, that is, the second time. The second time is the sum of the drainage time, the lifting time, the coke discharge time, the reset time and the coke feeding time. The drainage time is the time required for the recycled water in the drainage area 20 to be discharged into the water storage area 30, which is equal to the first time threshold. The lifting time is the time required for the active coke protection frame 101 to reach the first preset position and complete the coke discharge preparation. The coke discharge time is the time required for the active coke in the active coke protection frame 101 to be discharged. The reset time refers to the time required for the active coke protection frame 101 to return from the first preset position to the corresponding water inlet area 10 after completing the coke discharge and complete the coke feeding preparation. The coke feeding time is the time required for the active coke protection frame 101 to complete the coke feeding and reach the sewage inlet 10-1 to be able to take in water.
[0082] The second time threshold is a preset value, stored in the storage unit, and can be input or modified through the input unit. The second time threshold is a time period greater than or equal to zero, preferably a value greater than or equal to zero and less than or equal to 10 minutes.
[0083] The analysis unit may determine / adjust the maximum waiting time for cleaning of activated coke in each water inlet zone 10 in the following manner:
[0084] After obtaining a generated tree diagram based on the regenerated water data and the tree diagram model, the control mechanism predicts the cleaning time of the activated coke in the adsorption filter tank, generates a corresponding cleaning plan, and controls the saturated activated coke discharge mechanism, the regenerated activated coke addition mechanism, and the coke washing mechanism to clean the activated coke in the adsorption filter tank according to the cleaning plan.
[0085] The storage unit includes a tree graph model of the adsorption filtration tank, which includes a first node, a second node, and a third node, as shown in Figure 4. The number of the first nodes is the same as the number of water inlet zones 10 in the adsorption filtration tank, and is used to store the maximum waiting time for cleaning the activated coke in each water inlet zone 10. The second node is used to store the maximum waiting time difference between the maximum waiting times for cleaning the activated coke in two adjacent water inlet zones 10: the waiting time difference. The third node is used to store the cleaning interval between the cleaning of the activated coke in two adjacent water inlet zones 10.
[0086] The analysis unit sequentially places the maximum waiting time of each water inlet area 10 obtained in the activated coke cleaning remaining time estimation table into the first node of the tree graph model in order from large to small or from small to large.
[0087] The analysis unit calculates the difference between every two adjacent first nodes to obtain the maximum waiting time difference for cleaning the activated coke in every two adjacent water inlet areas 10, that is, the waiting time difference, and puts the waiting time difference into the corresponding second node.
[0088] The analysis unit subtracts the waiting time difference of each second node from the second duration to obtain the cleaning interval duration, and puts the cleaning interval duration into the corresponding third node. At this time, the analysis unit generates a first tree graph.
[0089] The analysis unit compares the cleaning interval duration of each third node with the second duration threshold,
[0090] When the cleaning intervals of the third nodes are all greater than or equal to the second duration threshold, the current first tree diagram is the optimal tree diagram, and the analysis unit generates a cleaning plan based on the current first tree diagram and the current time. The control mechanism cleans the activated coke in the adsorption filtration tank according to the cleaning plan.
[0091] When the cleaning interval duration of a third node includes a third node whose cleaning interval duration is less than the second duration threshold, the calculation unit modifies the third node whose cleaning interval duration is less than the second duration threshold. Specifically, the third node may be modified to have a cleaning interval duration equal to the second duration threshold. Simultaneously, the calculation unit modifies the second and first nodes connected to the third node to generate a second tree diagram. At this point, the second tree diagram is the optimal tree diagram. The calculation unit generates a cleaning plan based on the current second tree diagram and the current time. The control mechanism cleans the activated coke in the adsorption filtration tank according to the cleaning plan.
[0092] It should be noted that when the analysis unit modifies the third node, the second node and / or the first node in the first tree diagram, the modification is performed in the direction of the first node from large to small, that is, the third node close to the largest first node is modified first, and after the second node and the first node corresponding to the third node are modified, the next third node is modified in the direction of the first node from large to small.
[0093] A mobile coke-washing system utilizes a movable coke-washing mechanism and a control mechanism to predict the cleaning of activated coke. This system automatically cleans large quantities of activated coke in an adsorption filter tank, ensuring both the quality and speed of the recycled water after purification. Furthermore, a tree graph model is used to generate an activated coke cleaning plan, ensuring both automated cleaning and the efficiency of the adsorption filter tank.

However, these embodiments are merely illustrative, and it cannot be determined that the specific implementation methods of the present invention are limited to the description of these embodiments.
