Description

Technical Field

[0001] The present invention relates to the field of process equipment for coke dry quenching projects in coking enterprises, and more particularly to a driving device and control method for a coke guide rod. Background Art

[0002] In the coke dry quenching project of the coking industry, as a key equipment, the operation efficiency and stability of the coke dry quenching furnace are directly related to the quality and production efficiency of coke. At present, with the upgrading of coking environmental protection requirements, coke produced by coke ovens must be dry quenched, and the stable operation of coke dry quenching is directly related to the normal production of coking plants. The coke guide rod of the coke dry quenching furnace is a coke guide rod arranged at the bottom cone section of the coke dry quenching furnace, and the coke guide rods are evenly distributed at the bottom cone section of the coke dry quenching furnace. When the material level in the coke dry quenching furnace shows segregation, by inserting the coke guide rod into the coke dry quenching furnace, the coke at the position with a lower material level is blocked, the downward movement of the coke is slowed down, and the coke at the position where the coke guide rod is not inserted in the coke dry quenching furnace moves downward at a normal speed, so as to make the coke material levels around the furnace gradually level. In the initial stage of coke dry quenching start-up or after major repairs, problems such as coke powder caking and hanging materials at the bottom of the coke dry quenching furnace are common problems that cause the coke dry quenching furnace to be unable to reach its production capacity. This not only affects the normal operation of the coke dry quenching furnace, but also may lead to a decline in coke quality and an increase in production costs. Traditional treatment methods often rely on manual operation of the coke guide rod for intervention, but this method has problems such as high operation difficulty and low efficiency, and due to the lack of an effective driving device for the coke guide rod, it is often difficult to handle the hanging material problem in a timely and accurate manner, which may further lead to the deterioration of the hanging material problem and cause more serious production failures.

[0003] In view of the above problems, there is an urgent need for a driving device for the coke guide rod of the coke dry quenching furnace, which can conveniently and effectively adjust the coke guide rod, timely handle problems such as hanging materials and segregation in the coke dry quenching furnace, so as to improve production efficiency, reduce production costs, and bring significant economic and social benefits to enterprises and society. Summary of the Invention

[0004] In view of this, the present application provides a driving device and control method for a coke guide rod. The main purpose is to solve the technical problem of conveniently and effectively adjusting the insertion and extraction of the coke guide rod into the coke dry quenching furnace, and timely handling problems such as hanging materials and segregation in the coke dry quenching furnace, so as to improve production efficiency.

[0005] According to the first aspect of the present invention, there is provided a driving device for a coke guide rod, which is used for a coke dry quenching furnace and includes: a plurality of coke guide rods symmetrically arranged circumferentially along the bottom of the coke dry quenching furnace;

[0006] A fixed seat provided on the outer peripheral wall of the bottom of the coke dry quenching furnace for installing and supporting the coke guide rod;

[0007] A guiding device provided at one end of the coke guide rod close to the coke dry quenching furnace;

[0008] The driving device at least includes a driving part, and the driving part is electrically connected to each of the coke guide rods;

[0009] A support seat is provided on the coke guide rod and is located between the guiding device and the driving part, and the support seat is movably connected to the fixed seat.

[0010] Further, the driving device of the coke guide rod further includes: a sealing device, which is provided at the contact position between the coke guide rod and the dry quenching furnace, or is provided at the through hole where the coke guide rod passes through the fixed seat, the support seat and the guiding device.

[0011] Further, the driving device can adopt an electric or hydraulic driving method to provide driving force.

[0012] Further, the fixed seat is provided on the outer peripheral wall of the bottom of the dry quenching furnace, and each fixed seat is sleeved outside the coke guide rod.

[0013] Further, a second support seat is further included on the outer peripheral wall of the upper part of the bottom cone section of the dry quenching furnace;

[0014] The second support seat is provided on the upper part of the coke guide rod of the dry quenching furnace and is movably connected to the driving part.

[0015] Further, the bottom cone section of the dry quenching furnace is a conical structure with a gradually decreasing diameter from top to bottom.

[0016] According to the second aspect of the present invention, a control method for the driving device of the coke guide rod is provided, and the control method is realized based on the driving device of the coke guide rod as described in the above specification.

[0017] Further, the method includes: S1. Start the driving device, and obtain the temperature difference R = T2 - T1 in the dry quenching furnace at the first moment T1 and the second moment T2;

[0018] S2. Judge whether the temperature difference R in the dry quenching furnace at the first moment T1 and the second moment T2 is less than the first set value. If so, execute the program of extracting the coke guide rod from the dry quenching furnace.

[0019] Further, in S2, executing the program of extracting the coke guide rod from the dry quenching furnace includes: determining the number of coke guide rods to be extracted according to the temperature difference R in the dry quenching furnace at the first moment T1 and the second moment T2.

[0020] Further, before starting the driving device, it further includes: S01. After the coke guide rod on the first side is inserted into the dry quenching furnace, ensure that the descending height of the coke surface on the symmetrical side is the same.

At the same time, the electric or hydraulic driving method of the driving device provides a flexible driving force selection, adapting to different production requirements. In addition, in this application, the driving device is electrically connected to each coke guide rod, and remote operation can be achieved through the control system, greatly reducing the difficulty and risk of manual operation. The design of the movable connection between the support seat and the fixed seat makes the insertion and extraction of the coke guide rod into and out of the coke dry quenching furnace more stable and smooth, improving the convenience and accuracy of operation.

[0022] On the other hand, through the temperature monitoring and judgment mechanism in the control method in this application, the temperature change inside the coke dry quenching furnace can be obtained in real time, and whether to execute the extraction program of the coke guide rod is determined according to the temperature difference. This intelligent control method helps to optimize the temperature distribution inside the coke dry quenching furnace, reduce heat loss, and improve the cooling efficiency and quality of coke. Determining the number of coke guide rods to be extracted according to the temperature difference realizes precise adjustment of the insertion depth of the coke guide rod. This adjustment method not only helps to solve problems such as material hanging and segregation inside the coke dry quenching furnace, but also can achieve energy conservation and consumption reduction while ensuring production efficiency, reducing production costs.

[0023] The coke guide rod driving device and its control method of the present invention not only improve the production efficiency and coke quality of the coke dry quenching furnace, but also reduce production costs and energy consumption. The application of this innovative technology helps to promote the green development of the coking industry, improve the competitiveness of enterprises, and also brings significant economic and social benefits to society.

[0037] As Figures 1-4As shown in the figure, a driving device for a coke guide bar, which is used for a dry quenching furnace, includes: multiple coke guide bars 1, which are evenly and symmetrically arranged along the circumferential direction of the bottom of the dry quenching furnace, forming a solid barrier to effectively adjust the falling speed and direction of coke, and prevent local coking of coke in the dry quenching furnace; a fixed seat 2, which is arranged on the outer peripheral wall of the bottom of the dry quenching furnace and is used to install and support the coke guide bar 1; a guiding device 5, which is arranged at one end of the coke guide bar 1 close to the dry quenching furnace; the driving device at least includes a driving part 3, the driving part 3 is electrically connected to each coke guide bar 1, and as the core of the driving device, the driving part 3 provides a powerful driving force through electrical or hydraulic means to ensure that the coke guide bar can quickly and smoothly respond to control instructions. Each coke guide bar 1 is electrically connected or hydraulically connected to the driving part 3 through wires or hydraulic pipelines, ensuring stable signal transmission and efficient power transmission. A support seat 4 is arranged on the coke guide bar 1 and is located between the guiding device 5 and the driving part 3, and the support seat 4 is movably connected to the fixed seat 2.

[0038] In a feasible implementation manner, in order to improve the sealing performance of the device and prevent leakage of high-temperature gas or coke dust, the driving device of the coke guide bar further includes: a sealing device 6, which is arranged at the contact position between the coke guide bar 1 and the dry quenching furnace, or at the through hole where the coke guide bar 1 passes through the fixed seat 2, the support seat 4 and the guiding device 5. These sealing devices use high-temperature resistant and corrosion-resistant materials to ensure the sealing effect under long-term operation.

[0039] In another feasible implementation manner, the fixed seat 2 is arranged on the outer peripheral wall of the bottom of the dry quenching furnace, and each fixed seat 2 is sleeved outside the coke guide bar 1.

[0040] In a feasible implementation manner, a second support seat 7 is further included on the outer peripheral wall of the upper part of the bottom cone section 8 of the dry quenching furnace, providing additional support for the upper part of the coke guide bar. The second support seat 7 is arranged on the upper part of the coke guide bar 1 of the dry quenching furnace and is movably connected to the driving part 3. A second support seat is added on the outer peripheral wall of the upper part of the bottom cone section 8 of the dry quenching furnace, and the second support seat is connected to the driving part through a movable connection method.

[0041] In this embodiment, the bottom cone section of the dry quenching furnace described in the present application is a conical structure with a gradually decreasing diameter from top to bottom. This structure not only optimizes the flow path of coke but also improves the thermal efficiency of the dry quenching furnace and the cooling effect of coke.

[0042] Embodiment 2

[0043] A control method for a driving device of a coke guide bar, which is realized based on the driving device of the coke guide bar described in the above Embodiment 1.

[0044] In a feasible implementation, the method includes: S1. Start the driving device to obtain the temperature difference R = T2 - T1 in the coke dry quenching furnace at the first moment T1 and the second moment T2;

[0045] S2. Determine whether the temperature difference R in the coke dry quenching furnace at the first moment T1 and the second moment T2 is less than a first set value. If so, execute the program of withdrawing the coke guide bar from the coke dry quenching furnace.

[0046] In this implementation, the execution of the program of withdrawing the coke guide bar 1 from the coke dry quenching furnace in S2 includes: when executing the program of withdrawing the coke guide bar, further refine the adjustment strategy according to the specific value of the temperature difference R in the coke dry quenching furnace at the first moment T1 and the second moment T2. Specifically, compare R with a series of preset first set ranges (these ranges are obtained based on experimental data and experience summary, aiming to cover different coke cooling requirements and the operating state of the coke dry quenching furnace). Once R falls into a certain specific set range, the control system will automatically calculate the number of coke guide bars to be withdrawn. This calculation process comprehensively considers factors such as the size of the coke dry quenching furnace, the flow rate and type of coke, and the desired cooling effect, ensuring the accuracy and effectiveness of the adjustment.

[0047] For example, if R falls within the set range of "slightly low", the system may decide to withdraw only a small number of coke guide bars to fine-tune the coke falling speed; while if R is significantly lower than the first set value, indicating that the coke is cooled too quickly, the system may instruct to withdraw more coke guide bars to significantly slow down the coke flow, thereby optimizing the cooling effect.

[0048] In a feasible implementation, before starting the driving device, it further includes: S01. After the coke guide bar 1 on the first side is inserted into the coke dry quenching furnace, ensure that the descending height of the coke surface on the symmetric side is the same.

[0049] Embodiment 3

[0050] A driving system for a coke guide bar, which is implemented based on the driving device of the coke guide bar described in Embodiment 1 above.

[0051] In a feasible implementation, the system includes a control unit and a temperature measuring unit;

[0052] In a feasible implementation, after the control unit obtains the information that the coke guide bar 1 on the first side is inserted into the coke dry quenching furnace and obtains the information that the descending height of the coke surface on the symmetric side is the same, S1. The control unit starts the driving device, and the temperature measuring unit obtains the temperature difference R = T2 - T1 in the coke dry quenching furnace at the first moment T1 and the second moment T2 and sends the temperature difference R to the control unit;

[0053] S2. The control unit determines whether the temperature difference R in the coke dry quenching furnace between the first moment T1 and the second moment T2 is less than a first set value. If so, the program of withdrawing the coke guide bar from the coke dry quenching furnace is executed.

[0054] In this embodiment, the execution of the program of withdrawing the coke guide bar 1 from the coke dry quenching furnace in S2 includes: when executing the program of withdrawing the coke guide bar, the control system will further refine the adjustment strategy according to the specific value of the temperature difference R. Specifically, the system will compare R with a series of preset first set ranges (these ranges are obtained based on experimental data and experience summary, aiming to cover different coke cooling requirements and the operating status of the coke dry quenching furnace). Once R falls within a certain specific set range, the control system will automatically calculate the number of coke guide bars to be withdrawn. This calculation process comprehensively considers factors such as the size of the coke dry quenching furnace, the flow rate and type of coke, and the desired cooling effect, ensuring the accuracy and effectiveness of the adjustment. For example, if R falls within the "slightly low" set range, the system may decide to withdraw only a small number of coke guide bars to fine-tune the coke falling speed; while if R is significantly lower than the first set value, indicating that the coke is cooled too quickly, the system may instruct to withdraw more coke guide bars to significantly slow down the coke flow, thereby optimizing the cooling effect.
