[0036] The present invention is further described in detail below in conjunction with preferred embodiments. More details are elaborated 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 protection scope of the present invention should not be limited by the content of this specific embodiment.

[0037] The accompanying drawings are schematic diagrams of embodiments of the present invention. It should be noted that the drawings are only examples and are not drawn to scale, and should not be used to limit the actual protection scope of the present invention.

[0038] An automatic coke washing system and method for a large amount of active coke are used for automatic cleaning of active coke in a filter pool for large-area water purification, thereby improving water purification efficiency and ensuring water purification quality.

[0039] like Figure 1 As shown, an automatic coke washing method for a large amount of active coke is performed by an automatic coke washing system for a large amount of active coke. An automatic coke washing system for a large amount of active coke comprises a saturated active coke discharge mechanism, a regenerated active coke feeding mechanism, a coke washing mechanism, a water body monitoring mechanism 300 and a control mechanism, wherein the control mechanism is respectively connected to the saturated active coke discharge mechanism, the regenerated active coke feeding mechanism, the coke washing mechanism and the water body monitoring mechanism 300.

[0040] The active coke discharge mechanism is used to discharge the adsorption saturated active coke in the adsorption filter tank and transport it to the coke washing mechanism, which washes and regenerates the adsorption saturated active coke to obtain regenerated active coke. The regenerated active coke adding mechanism adds the regenerated active coke to the adsorption filter tank that discharges the adsorption saturated active coke, so that the adsorption filter tank performs adsorption filtration on the sewage entering the adsorption filter tank. The water body monitoring mechanism 300 is arranged at the outlet of the adsorption filter tank, detects the regenerated water obtained after being treated by the adsorption filter tank, obtains the regenerated water data, and sends the real-time monitoring data to the control mechanism. The control mechanism pre-judges and / or plans the route for the cleaning of the active coke based on the regenerated water data, so as to realize the automatic cleaning and regeneration of the active coke.

[0041] The active coke of the adsorption filtration tank can be arranged on the cross section of the adsorption filtration tank or on the longitudinal section of the adsorption filtration tank, and no specific limitation is made here. It should be noted that it is necessary to ensure that all sewage passes through the active coke of the adsorption filtration tank to achieve adsorption and purification of sewage by the active coke.

[0042] The activated coke is preferably activated coke particles.

[0043] The active coke discharge mechanism includes a frame taking-out device, an active coke protection frame 101 and an output pipe. The frame taking-out device is used to assist the active coke protection frame 101 to be separated from the adsorption filtration pool. The active coke protection frame 101 is used to carry the active coke. The output pipe is used to guide the active coke in the protection frame to the coke washing mechanism. The active coke protection frame 101 is set in the adsorption filtration pool. When the active coke is placed in the active coke protection frame 101, the floating of the active coke during the water purification process is avoided, which affects the water purification effect.

[0044] The frame taking-out device is connected to the active coke protection frame 101 , and the frame taking-out device may be a lifting device. When the control device issues an active coke cleaning command, the frame taking-out device takes the active coke protection frame 101 out of the adsorption filtration pool.

[0045] The size of the active coke protection frame 101 is consistent with the size of the water flow direction of the adsorption filtration pool in terms of the flow direction of the water flow during filtration, thereby ensuring that all sewage flows out after being adsorbed and filtered by the active coke.

[0046] Specifically, the length and width of one end of the active coke protection frame 101 close to the bottom of the filter pool are equal to the length and width of the bottom of the filter pool to ensure that all the sewage passes through the active coke. At this time, the sewage enters from the bottom of the adsorption filter pool and overflows from the adsorption filter pool after passing through the active coke. Alternatively, the active coke protection frame 101 divides the adsorption filter pool into two spaces in the vertical direction, that is, the length and width of one side of the active coke protection frame 101 that is perpendicular to the bottom and side of the adsorption filter pool contacts the inner wall of the adsorption filter pool. At this time, the sewage enters from the adsorption filter pool on one side of the active coke protection frame 101 and overflows from the adsorption filter pool on the other side of the active coke protection frame 101 after passing through the active coke.

[0047] Here, the active coke protection frame 101 is laid in the adsorption filtration tank as an example, and a specific description is given:

[0048] like Figure 2 As shown, the adsorption filtration tank is provided with an inlet area 10 and a drainage area 20, and the horizontal position of the inlet area 10 is lower than the drainage area 20. Each adsorption filtration tank can be provided with multiple inlet areas 10 and multiple drainage areas 20, each inlet area 10 corresponds to a drainage area 20, and the regenerated water in the multiple drainage areas 20 is collected in the water storage area 30, and the regenerated water in the water storage area 30 is recycled according to the water demand. The water storage area 30 is provided at one end of the drainage area 20 away from the inlet area 10, and the side of the drainage area 20 at one end of the water storage area 30 is provided, which is lower than the side of the drainage area 20 away from the end of the water storage area 30, so that the purified water in the drainage area 20 overflows to the water storage area 30.

[0049] The water inlet area 10 is arranged below the level of the corresponding drainage area 20, and each water inlet area 10 is respectively provided with an active coke protection frame 101. The water body monitoring mechanism 300 and the pumping device are arranged at one end of each drainage area 20 close to the water storage area 30. The water body monitoring mechanism 300 is arranged at 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 body monitoring mechanism 300 is arranged at the overflow port of the drainage area 20. The pumping device is arranged at one end of the drainage area 20 close to the water storage area 30 and close to the edge of the bearing surface, that is, it is arranged on the inner wall of the bottom surface of the drainage area 20 to ensure the discharge of the recycled water in the drainage area 20.

[0050] The pumping device may be a pump or other device that can discharge the regenerated water in the drainage area 20, and no specific limitation is made here.

[0051] The active coke protection frame 101 is disposed at one end of the water inlet area 10 adjacent to the drainage area 20, and 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, and the sewage inlet 10-1 can be disposed at any position lower than the horizontal position of the drainage area 20.

[0052] like Figure 3 As shown, the active coke protection frame 101 includes a first bearing area 104 and a second bearing area 105. The first bearing area 104 is arranged above the second bearing area 105. When the active coke protection frame 101 is placed in the adsorption filtration tank, the first bearing area 104 is far away from the sewage inlet 10-1, that is, the first bearing area 104 is adjacent to the drainage area 20. A feed port 102 is arranged at one end of the first bearing area 104 far away from the second bearing area 105. When the active coke is cleaned, it enters the active coke protection frame 101 through the feed port 102. A discharge port 103 is arranged at one end of the second bearing area 105 far away from the first bearing area 104. When the active coke in the active coke protection frame 101 needs to be cleaned, it is discharged from the active coke protection frame 101 through the discharge port 103 and enters the coke washing mechanism.

[0053] The shape and size of the first bearing area 104 in the 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 body passing through the water inlet area 10. The second bearing area 105 is preferably funnel-shaped, and the shape and size of the end of the second bearing area 105 connected to the first bearing area 104 match the shape and size of the first bearing area 104, and the shape of the end of the second bearing area 105 away from the first bearing area 104 matches the shape of the first bearing area 104, and the size is smaller than the first bearing area 104. The end of the discharge port 103 away from the first 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 active coke in the active coke protection frame 101, that is, in the vertical direction, the lowest position of the discharge port 103 and the position connected to the second load-bearing area 105 are on the same horizontal plane, and there is a downward inclined angle between the discharge port 103 and the horizontal plane.

[0054] 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 operation of adding or discharging the activated coke is performed. The feed port 102 is connected to one end of the output pipeline.

[0055] An automatic coke washing system for a large amount of active coke may include one or more coke washing mechanisms, wherein the control mechanism controls the coke washing mechanism to reach a specified position according to a cleaning command, thereby cleaning the active coke in different water inlet areas 10. The coke washing mechanism includes a walking unit and a cleaning unit, and the cleaning unit is arranged on the walking unit. The walking unit realizes the movement of the coke washing mechanism, and the cleaning unit cleans the active coke.

[0056] The walking unit includes a carrying platform, a walking wheel, a driving device and a braking device. The walking wheel is installed on the side of the carrying platform; the driving device is connected to the walking wheel to provide walking power for the walking wheel; the braking device is adjacent to the walking wheel and is used to fix the walking unit at a specified position, thereby fixing the cleaning unit.

[0057] The cleaning unit comprises a cleaning bucket, and the cleaning bucket is provided with a cleaning feed inlet and a cleaning discharge inlet. The cleaning feed inlet is connected to an end of the output pipeline away from the feed inlet 102 of the active coke protection frame 101.

[0058] 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.

[0059] The regenerated active coke adding mechanism comprises an active coke storage unit and a traveling unit. The active coke storage unit is used to store the cleaned regenerated active coke, and the traveling unit places the active coke storage unit at a designated position to add active coke or receive regenerated active coke. The active coke storage unit is fixed on the traveling unit.

[0060] The active coke storage unit includes a regenerated coke feed port and a regenerated coke discharge port, and both the regenerated coke feed port and the regenerated coke discharge port are controllable opening and closing ports. When the active coke storage unit receives regenerated active coke, the regenerated coke feed port is connected to the cleaning discharge port through an output pipe. When the active coke storage unit adds regenerated active coke to the active coke protection frame 101, the regenerated coke discharge port is connected to the feed port 102 of the active coke protection frame 101 through an output pipe.

[0061] 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 the monitoring data of the water body monitoring mechanism 300, and send control commands to the active coke discharge mechanism, the regenerated active coke addition mechanism, and the coke washing mechanism. The analysis unit is used to pre-judge the cleaning of the active coke in the water inlet area 10, realize the timely cleaning of the active coke in the target water inlet area 10, and plan the coke washing route according to the position of the coke washing mechanism, as well as the coke replacement time of the active coke protection frame 101 in the target water inlet area 10. The storage unit is used to store preset data and store the work logs of the active coke discharge mechanism, the regenerated active coke addition mechanism, the coke washing mechanism, and the water body monitoring mechanism 300. The input unit can input different control commands and input / modify preset data. The display unit is used to display the active coke cleaning status predicted by the analysis unit.

[0062] When the activated coke needs to be cleaned, the control mechanism controls the sewage inlet 10-1 to stop taking in water, and starts the pumping device 20-1 to discharge the purified water in the drainage area 20 into the water storage area 30, so as to avoid 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.

[0063] 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 focus 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.

[0064] The control mechanism controls the frame taking-out device to take out the target active coke protection frame 101 to the corresponding first preset position according to the coordinates of the target active coke protection frame 101. At the same time, after 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 discharge port 103 of the active coke protection frame 101 is connected to the feed port of the washing bucket through the output pipeline, and the discharge port 103 is opened to add the active coke in the active coke protection frame 101 into the washing bucket, and the washing bucket washes the active coke.

[0065] 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.

[0066] 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.

[0067] 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 when the active coke protection frame 101 in each drainage area 20 in the adsorption filtration pool is performing a coke washing and coke discharge operation.

[0068] The third preset position refers to the position of the regenerated active coke adding mechanism corresponding to the water inlet area 10 where the target active coke protection frame 101 is located when the active coke protection frame 101 in each drainage area 20 in the adsorption filtration pool is performing the regenerated coke feeding operation.

[0069] The storage unit of the control mechanism is preset with a coke-washing map, which includes the first preset position, the second preset position and the third preset position corresponding to the active coke protection frame 101 in each drainage area 20. The coke-washing map can be input or modified through the input device.

[0070] 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.

[0071] The coke washing map is a three-dimensional map, and its coordinates include an x-axis, a y-axis, and a z-axis. The plane formed by the x-axis and the y-axis is a horizontal plane, and the z-axis is a vertical height relative to the horizontal plane. The coke washing map is marked with coordinates (x1, y1, z1), (x2, y2, z2) ... (xn, yn, zn) of the active coke protection frame 101 in each drainage area 20, where n is the number of active coke protection frames 101, that is, the number of water inlet areas 10 included in the adsorption filtration tank.

[0072] The coke washing map includes a first layer and a second layer, wherein the first layer is a three-dimensional real scene map or a three-dimensional proportional map of the adsorption filtration pool, and the second layer is a coordinate map, and the second layer is covered on the first layer. In the second layer, the coordinates of the position of the active coke protection frame 101 in each drainage area 20 of the adsorption filtration pool are marked corresponding to the position of the active coke protection frame 101 in the drainage area 20 in the first layer, respectively, and the coordinates of the position of the active coke protection frame 101 in each drainage area 20 are connected to the coordinates of the first preset position, the second preset position and the third preset position corresponding to the active coke protection frame 101, and the coordinates of the first preset position, the second preset position and the third preset position corresponding to the active coke protection frame 101 are marked on the second layer corresponding to the position of the first layer.

[0073] 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.

[0074] When the active coke in the active coke protection frame 101 is completely discharged, the control mechanism controls the frame taking-out device to put the target active coke protection frame 101 back to the original water inlet area 10 (original coordinates). The frame taking-out device may include a quality monitoring device, and the control mechanism receives the quality data acquired by the quality monitoring device in real time. When the difference between the quality of the active coke protection frame 101 before and after the active coke is discharged is greater than or equal to a first quality threshold, the control mechanism determines that the active coke in the active coke protection frame 101 is completely discharged. The first quality threshold is a preset value, which can be input or modified through the input device.

[0075] After the frame taking-out device puts the target active coke protection frame 101 back to the original water inlet area 10 (original coordinates), the control mechanism controls the traveling unit of the regenerated active coke adding mechanism to place the active coke storage unit at the third preset position corresponding to the water inlet area 10 where the target active coke protection frame 101 is located, and then connects the regenerated coke discharge port of the active coke storage unit to the feed port 102 of the target active coke protection frame 101 through the output pipeline, and opens the regenerated coke discharge port to add the regenerated active coke of the active coke storage unit to the target active coke protection frame 101, so as to realize the cleaning and regeneration of the active coke in the target active coke protection frame 101. The active coke stored in the active coke storage unit is a portion of active coke required for the active coke protection frame 101.

[0076] In the entire automatic coke washing system, the amount of active coke required for one active coke protection frame 101 is one portion, and the entire automatic coke washing system includes at least one portion of active coke equal to the sum of the number of active coke protection frames 101 and the number of cleaning mechanisms. Thus, after the active coke that needs to be cleaned and regenerated in the active coke protection frame 101 is discharged, the regenerated active coke that has been cleaned can be added, thereby improving the water purification efficiency of the adsorption filter tank.

[0077] The automatic coke washing system for a large amount of active coke is described below in conjunction with a preferred embodiment.

[0078] The coke washing mechanism is provided with one, and at this time, the active coke in different water inlet areas 10 of the adsorption filtration tank are all cleaned by the coke washing mechanism, thereby ensuring the purification effect of the adsorption filtration tank.

[0079] However, when the active coke in different water inlet areas 10 all need to be cleaned, the active coke in the water inlet area 10 that needs to be cleaned later needs to wait until the active coke in the water inlet area 10 that needs to be cleaned earlier is cleaned before the active coke can be cleaned. During this waiting time, in order to ensure the water quality of 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.

[0080] In order to solve the above problems, the analysis unit of the control mechanism carries out activated coke cleaning planning according to 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.

[0081] 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, and can also be updated according to the maximum active coke cleaning waiting time corresponding to the recycled water data detected by the water body detection mechanism.

[0082] The active coke cleaning remaining time estimation table includes different recycled water data and the maximum active coke cleaning waiting times corresponding to the different recycled water data.

[0083] Here, the water body monitoring mechanism 300 is taken as a water flow velocity monitoring device as an example for explanation.

[0084] The water flow rate monitoring device monitors the flow rate of the 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 active coke cleaning remaining time estimation table includes different regenerated water flow rate sections and the maximum active coke cleaning waiting time corresponding to different regenerated water flow rate sections.

[0085] The calculation unit of the control mechanism predicts the time required for cleaning the active coke in each water inlet area 10 of the adsorption filter tank according to 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 active 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.

[0086] The communication unit of the control mechanism receives in real time the water flow data detected by the water flow velocity 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 velocity segment in the activated coke cleaning remaining time estimation table to which the regenerated water flow velocity in the current water flow data belongs, and determines / adjusts the maximum waiting time for activated coke cleaning in each water inlet area 10 according to the regenerated water flow velocity segment and the maximum waiting time for activated coke cleaning corresponding to the current water flow data.

[0087] The analysis unit sorts the maximum waiting time for cleaning 10 active cokes in each water inlet area, calculates the maximum waiting time for cleaning 10 active cokes in two adjacent water inlet areas, and obtains the maximum waiting time difference for cleaning 10 active cokes in each two adjacent water inlet areas. The maximum waiting time difference for cleaning 10 active cokes in each two adjacent water inlet areas is the waiting time difference. The analysis unit subtracts the obtained waiting time difference from the second time length to obtain the cleaning interval time length, and then the analysis unit determines / adjusts the maximum waiting time for cleaning 10 active cokes in each water inlet area according to the relationship between the cleaning interval time length and the second time length threshold.

[0088] The storage unit stores the time required for the coke washing operation, i.e., 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 entry 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 entry preparation. The coke entry time is the time required for the active coke protection frame 101 to complete the coke entry and to be able to enter the sewage inlet 10-1.

[0089] The second duration threshold is a preset value, stored in the storage unit, and can be input or modified through the input unit. The second duration 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.

[0090] The analysis unit may determine / adjust the maximum waiting time for cleaning of active coke in each water inlet zone 10 in the following manner:

[0091] 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 active coke in the adsorption filter tank, generates a corresponding cleaning plan, and controls the saturated active coke discharge mechanism, the regenerated active coke addition mechanism, and the coke washing mechanism to clean the active coke in the adsorption filter tank according to the cleaning plan.

[0092] The storage unit includes a tree graph model of the adsorption filtration tank, and the tree graph model includes a first node, a second node and a third node, such as Figure 4 As shown. The number of the first nodes is the same as the number of the water inlet areas 10 in the adsorption filtration tank, and is used to place the maximum waiting time for the active coke cleaning of each water inlet area 10. The second node is used to place the maximum waiting time difference between the maximum waiting times for the active coke cleaning of two adjacent water inlet areas 10: the waiting time difference. The third node is used to place the cleaning interval length of the active coke cleaning of two adjacent water inlet areas 10.

[0093] The analysis unit sequentially places the maximum waiting time of each water inlet area 10 obtained in the active 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.

[0094] The analysis unit makes a difference between every two adjacent first nodes to obtain the maximum waiting time difference for active coke cleaning 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.

[0095] 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.

[0096] The calculation unit compares the cleaning interval duration of each third node with the second duration threshold,

[0097] When the cleaning intervals of the third nodes are all greater than or equal to the second time threshold, the current first tree diagram is the optimal tree diagram, and the analysis unit generates a cleaning plan according to the current first tree diagram and the current time. The control mechanism cleans the active coke in the adsorption filtration tank according to the cleaning plan.

[0098] When the cleaning interval duration of the third node includes a third node that is less than the second duration threshold, the analysis unit modifies the third node whose cleaning interval duration is less than the second duration threshold, and specifically, the third node may be modified to be equal to the cleaning interval duration of the second duration threshold. At the same time, the analysis unit modifies the second node and the first node connected to the third node to obtain a second tree diagram. At this time, the second tree diagram is the optimal tree diagram, and the analysis unit generates a cleaning plan based on the current second tree diagram and the current time. The control mechanism cleans the active coke in the adsorption filtration tank according to the cleaning plan.

[0099] 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.
