Description

Technical Field

[0001] The invention relates to the technical field of dry coke quenching technology, and in particular to coke discharge cooling equipment suitable for a dry coke quenching furnace. Background Art

[0002] Coke quenching is an important step in the coke production process. There are two types of coke quenching: wet quenching and dry quenching. Currently, most of them use dry quenching to achieve environmental protection and energy saving requirements. A set of dry quenching system engineering consists of coke quenching furnace, primary dust removal, preheating boiler, secondary dust removal and circulating fan.

[0003] The CDQ furnace consists of an upper cone, a pre-storage chamber (annular air duct), an inclined air duct and a cooling chamber. The CDQ process is relative to the traditional wet process for treating red coke. It uses inert gas to cool the red-hot coke in the CDQ furnace and discharge the coke. After the heat exchange, the inert gas is subjected to the initial dust removal and then exchanges heat with desalted water in the boiler to generate steam that is recycled under the suction of the circulating fan after the secondary dust removal.

[0004] In conjunction with the above, it is necessary to explain that the working principle of the cooling section is as follows: in the cooling section, the coke flows from top to bottom, while the inert circulating gas flows from bottom to top, and the two exchange heat in the cooling section. The coke is gradually cooled to below 200°C by contact with the circulating gas, and then discharged from the bottom of the CDQ furnace;

[0005] This countercurrent heat exchange method makes the temperature difference between coke and gas smaller, and improves the heat exchange efficiency. For the coke discharge process, the prior art uses a multi-format rotary discharger with sealing performance, which can discharge continuously and has good sealing and wear resistance. In the coke discharge process, in order to adapt to different material flow rates, the speed can be adjusted and the size of the silo can be manually adjusted. However, in the dry quenching process, the material flow rate is not always constant under the influence of various parameters such as circulating air volume, coke particle size, loading distribution and equipment status. Therefore, under the premise that the other parameters are fixed values, the constant setting of the material flow rate cannot be achieved by frequently manually adjusting the size of the silo and the speed, and the process progress of the dry quenching is affected by the lack of intelligent dynamic adjustment function;

[0006] To this end, this application proposes a solution. Summary of the invention

DETAILED DESCRIPTION

[0035] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1: In view of the technical problem that the constant setting of the material flow cannot be achieved by frequently manually adjusting the size of the silo and the speed under the premise that the other parameters are fixed values, and there is no intelligent dynamic adjustment function, the following technical solution is proposed:

[0037] Reference Figure 1 - Figure 2 , Figure 4 , Figure 7 - Fig.15 As shown, the coke discharge cooling device suitable for the dry quenching coke oven in this embodiment comprises a cooling chamber 1 connected to the dry quenching coke oven body and a coke discharge box 5 connected to the bottom of the cooling chamber 1, a blast device 4 is transversely arranged at the bottom of the cooling chamber 1, an inner furnace lining 7 connected to the inner wall of the cooling chamber 1 is arranged at the outer peripheral side of the cooling chamber 1 corresponding to the blast device 4, a coke discharge assembly 8 for uniformly discharging the coke after cooling is arranged through the bottom of the inner furnace lining 7 in the cooling chamber 1, a coke inlet connected to the inside of the cooling chamber 1 is opened at the upper end of the outer ring side of the coke discharge box 5, and a coke outlet is opened at the lower end of the outer ring side of the coke discharge box 5 corresponding to the coke inlet, and the coke outlet corresponds to the coke conveying belt;

[0038] The coke discharge assembly 8 includes a rotating ring seat 15 which is rotatably arranged in the coke discharge box 5 and is sequentially distributed along the axial direction. Each rotating ring seat 15 is rotatably mounted with a material-dispensing structure through an arc groove 25 on the outer ring side. The material-dispensing structure includes a transmission rod 10 and a grid plate 9 connected to each other. The end surface lines of the grid plates 9 on each group of material-dispensing structures sequentially distributed along the axial direction are distributed in a spiral line. The transmission rod 10 penetrates the rotating ring seat 15 and protrudes to the inner ring side.

[0039] The outer driving ring 11 and the inner driving ring 17 contacting the protruding part of the transmission rod 10 are respectively installed on the front and rear sides of the inner ring side of the rotating ring seat 15, and the inner ring sides of the outer driving ring 11 and the inner driving ring 17 are both installed with a driving motor 2 for driving rotation. The transmission rod 10 and the dividing plate 9 in the coke discharge assembly 8 are rotatably arranged outside the rotating ring seat 15, and the end of the dividing plate 9 is in contact with the inner wall of the coke discharge box 5.

[0040] Reference Figure 3 and Figure 4 and Figure 8 As shown, the gap between the grid plates 9 is used as a silo, and the driving motor 2 is used as the driving component of the coke discharge assembly 8 to discharge the coke falling into the coke discharge box 5 through the silo, and the end surface line of the grid plate 9 is distributed in a spiral line, so that the coke can be discharged evenly and has a good air locking function, avoiding the formation of a gap between the coke discharge box 5 and the cooling chamber 1, and preventing dust from entering and affecting the smooth cooling of the coke;

[0041] It is important to note that: Fig.13 As shown, the installation method of the material-shifting structure is as follows: the transmission rods 10 are all rotatably connected to the rotating ring seat 15, and the adjacent transmission rods 10 and the dividing plates 9 are staggeredly distributed and respectively contact and frictionally connected with the outer drive ring 11 and the inner drive ring 17. Specifically, when the outer drive ring 11 rotates, it drives one group of the material-shifting structures to rotate, and the adjacent group of material-shifting structures drives the opposite side to rotate under the rotation of the inner drive ring 17, that is, the outer drive ring 11 can drive several groups of material-shifting structures distributed at intervals to rotate, and the inner drive ring 17 drives the material-shifting structures located between the above-mentioned material-shifting structures to rotate, so as to avoid interference motion;

[0042] The inner ring sides of the outer driving ring 11 and the inner driving ring 17 are both equipped with driving components for driving rotation, and the driving components include a chassis 6 and a driving motor 1 arranged outside the focus removal box 5, the driving motor 1 is embedded in the chassis 6 and the output ends are respectively equipped with a rotating rod 1 21 and a rotating rod 22, the driving rotation direction of the driving motors respectively connected to the rotating rod 1 21 and the rotating rod 22 is opposite, and the driving motor is a forward and reverse motor, and the driving motor drives the rotating rod 1 21 and the rotating rod 22 to rotate to realize the clockwise and counterclockwise rotation of the outer driving ring 11 and the inner driving ring 17.

[0043] The cooling chamber 1 is provided with material level meters which are vertically and equidistantly distributed. An angle sensor is embedded in the inner side of the corresponding grid plate 9 of the coke discharge box 5. An integrated module is communicatively connected with the material level meter, the angle sensor, the drive motor 1 and the drive motor 2. The integrated module includes a processor, a material level detection unit, a feedback analysis unit and an opening and closing control unit which are communicatively connected.

[0044] The material level detection unit is used to obtain the material level value LWz and the expansion angle value ZKz during the operation of the dry quenching coke oven, and send the material level value LWz and the expansion angle value ZKz to the feedback analysis unit through the processor, wherein the material level value includes the coke accumulation height in the dry quenching coke oven, and the expansion angle value includes the gap angle between the sides of two adjacent groups of material shifting structures, which is specifically manifested as the angle between the adjacent sides of a pair of grid plates 9;

[0045] The feedback analysis unit receives the material level value LWz and the opening angle value ZKz, and constructs the calculation formula of the material opening coefficient LK , where a>b>0, and k>0, a and b are preset proportional coefficients, k is a preset fault tolerance factor coefficient, and the material opening coefficient is compared and analyzed with the material opening coefficient threshold preset by the processor, wherein the comparison and analysis process is as follows:

[0046] The feedback analysis unit obtains the material level value LWz and the expansion angle value ZKz during the operation of the dry quenching coke oven, and obtains the material opening coefficient after numerical calculation of the material level value LWz and the expansion angle value ZKz. When the material opening coefficient is greater than the material opening coefficient threshold, it indicates that the discharge flow of the coke material in the current dry quenching coke oven operation is reduced and a blockage occurs. At this time, a reduction amplitude variable gap signal is generated and sent to the opening and closing control unit;

[0047] When the material opening coefficient is within the material opening coefficient threshold, it means that the coke discharge flow rate of the current CDQ coke oven operation is within the normal range and no signal is generated;

[0048] When the material opening coefficient is less than the material opening coefficient threshold, it means that the coke discharge flow rate of the current CDQ coke oven is too fast and a semi-no-load operation phenomenon occurs. At this time, an expansion gap signal is generated and sent to the opening and closing control unit.

[0049] The opening and closing control unit is used to adjust the speed of the second driving motor and the expansion size of the silo;

[0050] When the opening and closing control unit receives the amplitude reduction and gap change signal, it will send a control signal to the drive motor 1 and the drive motor 2. The drive motor 1 starts and drives the rotating rod 1 21 and the rotating rod 22 to complete the rotation. The rotating rod 1 21 and the rotating rod 22 drive the outer drive ring 11 and the inner drive ring 17 to rotate respectively. The rotation of the outer drive ring 11 drives the several groups of transmission rods 10 and the grid plates 9 frictionally connected thereto to rotate clockwise. The synchronous rotation of the inner drive ring 17 drives the adjacent groups of transmission rods 10 and grid plates 9 frictionally connected thereto to rotate counterclockwise until the adjacent grid plates 9 are in contact and fit. Under the combined action of the two, the gap between the adjacent grid plates 9 is eliminated, and the "amplitude reduction" action with the grid plates 9 as the "amplitude" is realized, that is, the capacity of a single group of silos is expanded;

[0051] The synchronous drive motor 2 drives the entire coke discharge assembly 8 to increase its rotation speed, and discharges the coke that has been cooled in the cooling box 1 evenly and quickly, avoiding the blockage of the coke discharge from the cooling chamber 1 to the coke discharge box 5, thereby improving the processing efficiency of the dry quenching coke oven;

[0052] When the opening and closing control unit receives the widening gap changing signal, it will send a control signal to the drive motor 1 and the drive motor 2. The drive motor 1 starts and drives the rotating rod 1 21 and the rotating rod 22 to complete the rotation. The rotating rod 1 21 and the rotating rod 22 drive the outer drive ring 11 and the inner drive ring 17 to rotate respectively. The rotation of the outer drive ring 11 drives the several groups of transmission rods 10 and the grid plates 9 frictionally connected thereto to rotate counterclockwise. The synchronous rotation of the inner drive ring 17 drives the adjacent groups of transmission rods 10 and the grid plates 9 frictionally connected thereto to rotate clockwise. Under the combined effect of the two, the gap between the adjacent grid plates 9 is increased, and the "widening" action with the grid plates 9 as the "width" is realized, that is, the capacity of a single group of silos is reduced.

[0053] The synchronous drive motor 2 drives the entire coke discharge assembly 8 to reduce its rotation speed, slowly and evenly discharges the coke that has been cooled in the cooling box 1, avoiding the "blowing out" of the circulating inert gas caused by the semi-unloaded operation phenomenon, and improving the coke cooling efficiency;

[0054] Basic principle: The present invention is basically the same as the conventional coke removal principle of the dry quenching coke oven, and the difference lies in that: through the setting of the variable amplitude coke removal component 8, the coke after cooling can be intelligently determined according to the material level and material flow rate in the cooling furnace body, and the material level value and the expansion angle value are combined to measure the parameters, and the control signal output is realized by the material opening coefficient, and finally the speed adjustment of the driving component and the size of the silo are completed to achieve the purpose of dynamic adjustment of the coke removal speed. At the same time, it can also effectively prevent the low coke processing efficiency caused by semi-empty operation and overload operation, and finally achieve the constant setting of the material flow rate by adopting the speed adjustment and the silo size adjustment mode under the premise that the other parameters are fixed values, and have the intelligent dynamic adjustment function;

[0055] Embodiment 2: This embodiment further optimizes the structure of the driving assembly of the material discharging structure in Embodiment 1, including a rotating rod 1 21 and a rotating rod 22 extending into the coke discharge box 5, and an outer driving gear 13 and an inner driving gear 19 corresponding to the outer driving ring 11 and the inner driving ring 17 are installed in sequence on the outside;

[0056] The inner ring sides of the outer driving ring 11 and the inner driving ring 17 are respectively provided with inner ring teeth 12 and inner ring teeth 2 18, the inner ring teeth 12 mesh with the outer driving gear 13, and the inner ring teeth 2 18 mesh with the inner driving gear 19. The outer driving ring 11 is provided with guide holes 14 distributed at intervals, and the inner driving ring 17 is provided with guide rods 20 matching the guide holes 14 on the outer side close to the outer driving ring 11, and the inner driving ring 17 drives the guide rods 20 to move in the guide holes 14 when the inner driving ring 17 rotates;

[0057] It should be noted that: refer to Figure 3 , Figure 5 , Figure 6 and Fig.10 As shown, after the rotating rod 1 21 and the rotating rod 22 are started and rotated by the driving motor 1, the rotating rod 1 21 drives the outer driving gear 13 to rotate, and the rotating rod 2 22 drives the inner driving gear 19 to rotate, and the outer driving ring 11 and the inner driving ring 17 respectively complete the driving rotation through the inner ring teeth 12 meshing with the outer driving gear 13 and the inner ring teeth 18 meshing with the inner driving gear 19, thereby realizing power supply.

[0058] In addition, refer to Fig.11 - Fig.13 As shown, the stable rotation between the outer drive ring 11 and the inner drive ring 17 is also achieved through the guide structure, which is as follows: when the outer drive ring 11 and the inner drive ring 17 rotate relative to each other, the inner drive ring 17 moves in the guide hole 14 on the outer drive ring 11 through the guide rod 20, and the rotation between the outer drive ring 11 and the inner drive ring 17 is achieved by the limiting effect of the guide hole 14.

[0059] Embodiment 3: This embodiment is combined with Embodiment 1 and Embodiment 2. The use process of the present invention is in the process of discharging the cooled coke from the coke discharge box 5 in "the red coke is loaded from the top of the dry quenching furnace, the low-temperature inert gas is blown into the red coke layer in the cooling section of the dry quenching furnace (referred to as the cooling chamber 1 here) by the circulating fan 4, and the sensible heat of the red coke is absorbed. The cooled coke is discharged from the coke discharge box 5 at the bottom of the dry quenching furnace". The process and principle of the present invention include the following steps:

[0060] Step 1: Coke falls from the upper part of the cooling chamber 1 into the bottom coke discharge assembly 8 and gradually accumulates in the cooling chamber 1. The integrated module obtains the material level value and the expansion angle value parameter values ​​in the cooling chamber 1 in real time through the material level meter and the angle sensor;

[0061] Step 2: Obtain the parameter value in real time according to the above step 1, and substitute it into the material opening coefficient calculation formula to obtain the material opening coefficient, compare the material opening coefficient with the material opening coefficient threshold, output the decreasing gap signal and the expanding gap signal, and simultaneously adjust the speed of the drive motor 2 and the expansion size of the silo;

[0062] Step 3: In step 2, when the amplitude reduction gap changing signal is output, a control signal is sent to the drive motor 1 and the drive motor 2. The drive motor 1 is started to drive the rotating rod 1 21 and the rotating rod 2 22 to complete the rotation. The rotating rod 1 21 and the rotating rod 22 respectively drive the outer drive ring 11 and the inner drive ring 17 to rotate. The rotation of the outer drive ring 11 drives the plurality of groups of transmission rods 10 and the grid plates 9 frictionally connected thereto to rotate clockwise. The synchronous rotation of the inner drive ring 17 drives the adjacent groups of transmission rods 10 and the grid plates 9 frictionally connected thereto to rotate counterclockwise until the adjacent grid plates 9 are in contact and fit. Under the combined action of the two, the gap between the adjacent grid plates 9 is eliminated, and the "amplitude reduction" action with the grid plates 9 as the "amplitude" is realized, that is, the capacity of a single group of silos is expanded.

[0063] The synchronous drive motor 2 drives the entire coke discharge assembly 8 to increase its rotation speed, and discharges the coke that has been cooled in the cooling box 1 evenly and quickly, avoiding the blockage of the coke discharge from the cooling chamber 1 to the coke discharge box 5;

[0064] Step 4: In step 2, when the expansion gap changing signal is output, a control signal is sent to the drive motor 1 and the drive motor 2. The drive motor 1 is started to drive the rotating rod 1 21 and the rotating rod 22 to complete the rotation. The rotating rod 1 21 and the rotating rod 22 respectively drive the outer drive ring 11 and the inner drive ring 17 to rotate. The rotation of the outer drive ring 11 drives the several groups of transmission rods 10 and the grid plates 9 frictionally connected thereto to rotate counterclockwise. The synchronous rotation of the inner drive ring 17 drives the adjacent groups of transmission rods 10 and the grid plates 9 frictionally connected thereto to rotate clockwise. Under the combined effect of the two, the gap between the adjacent grid plates 9 is increased, and the "expansion" action with the grid plates 9 as the "width" is realized, that is, the capacity of a single group of silos is reduced;

[0065] The synchronous drive motor 2 drives the entire coke discharge assembly 8 to reduce its rotation speed, slowly and evenly discharging the coke that has been cooled in the cooling box 1, thereby avoiding "blowing out" of the circulating inert gas caused by semi-idle operation.

[0066] In summary, the present invention is based on the first, second and third embodiments, and is different from the conventional coke removal by cooling in the dry quenching coke oven in that: on the one hand, the coke after cooling can be intelligently determined according to the material level and material flow rate in the cooling furnace body by setting the variable amplitude coke removal assembly, and the material level value and the expansion angle value are combined to measure the parameters, and the control signal output is realized by the material opening coefficient, and finally the speed adjustment of the driving assembly and the size of the silo are completed, so as to achieve the purpose of dynamic adjustment of the coke removal speed;

[0067] At the same time, it can also effectively prevent the problem of low coke processing efficiency caused by semi-empty operation and overload operation, and finally achieve the constant setting of material flow by adjusting the speed and the size of the silo under the premise that the other parameters are fixed values. It has the function of intelligent dynamic adjustment. On the other hand, the coke discharge components that do not interfere with each other are combined with the material shifting structure to achieve uniform discharge of cooled coke, and ensure the airtight protection of the dry quenching coke oven during the discharge process. After the comprehensive coordination of the two, the processing efficiency of the dry quenching coke oven is improved, and the continuous discharge of cooled coke is realized.
