Description

Technical Field

[0001] This utility model belongs to the field of ash removal technology for dry quenching coke boilers, and specifically relates to a bottom ash removal device for dry quenching coke boilers. Background Technology

[0002] Patent application number 202222120522.8 proposes a dry quenching system and a dry quenching boiler outlet flue ash discharge device. Dust generated during coking in the dry quenching boiler will accumulate at the bottom of the flue. This application proposes to collect dust by setting up an ash collection section at the bottom of the flue and using a material level monitoring device to monitor the amount of ash accumulation. The material level monitoring device controls the opening of the ash discharge valve, and the dust is discharged from the ash discharge valve to the outside of the flue. This automatic ash discharge method helps to ensure the smooth flow of the flue and improve the production efficiency of dry quenching.

[0003] In the existing technology, the ash discharge valve directly discharges coke powder, which easily pollutes the atmospheric environment, and residual powder is easily left at the bottom of the device. If the coke powder is extracted by an air pump, the coke powder sticks together, which easily leads to greater resistance of the air pump when pumping air, resulting in poor coke powder discharge and low ash discharge efficiency.

Detailed Implementation

[0023] The following are specific implementation cases and appendices. Figure 1-2 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0024] A bottom ash discharge device for a dry quenching coke boiler 10 includes: an electric sump valve 12, a distribution pipe 13, a distribution device, a connecting pipe 14, a telescopic hose 15, a vacuum pump truck connection port 16, and an auxiliary vacuum valve 17. The electric sump valve 12 is located between the dry quenching coke boiler 10 and the secondary dust collector 11, and is positioned at the bottom of the dry quenching coke boiler 10. The distribution pipe 13 is connected to the output end of the electric sump valve 12. The distribution device is located inside the distribution pipe 13. One end of the connecting pipe 14 is connected to the distribution pipe 13. One end of the telescopic hose 15 is connected to one end of the connecting pipe 14. The vacuum pump truck connection port 16 is connected to the other end of the telescopic hose 15. The auxiliary vacuum valve 17 is located at the connecting pipe 14.

[0025] Using the above structure, the coke powder accumulated in the dry quenching boiler 10 is discharged in batches through the electric distribution valve 12, and the falling coke powder is ensured to be loose and evenly distributed through the material distribution device, thereby reducing the adhesion between coke powders and reducing the resistance encountered by the suction pump truck during suction, thus improving the efficiency of ash removal. When the suction volume of the suction pump truck is large, but the air intake volume in the connecting pipe 14 is insufficient to support efficient suction operation, the auxiliary suction valve 17 is opened to allow a small amount of gas to enter the connecting pipe 14, thereby increasing the flow rate in the connecting pipe 14 and accelerating the efficiency of the suction pump truck in extracting coke powder.

[0026] Specifically, by combining the telescopic hose 15 with the air pump truck connection port 16, it is possible to quickly connect to the air pump truck's suction pipe. Furthermore, the telescopic hose 15 can adapt to different installation positions and angles, thus improving the flexibility of the device.

[0027] Specifically, coke powder is extracted by vacuum pump trucks to prevent it from spilling out and polluting the atmosphere.

[0028] Specifically, by timely discharging the coke powder accumulated at the bottom of the dry quenching boiler 10 during its operation, the overall resistance of the dry quenching system is maintained, the motor power of the power source (circulating fan) is reduced, thereby improving the economic efficiency of the dry quenching system and preventing damage to the secondary dust collector 11 and subsequent equipment due to excessive ash accumulation in the system.

[0029] In an embodiment of this utility model, the material dispensing device includes: an installation part 18, a placement groove 19, and a material dispensing plate 20; the installation part 18 is fixed inside the material dispensing pipe 13; the placement groove 19 is a T-shaped groove and is disposed inside the installation part 18; the material dispensing plate 20 is provided with multiple material dispensing ports and is installed inside the placement groove 19; wherein, the output end of the electric dispensing valve 12 is located above the material dispensing plate 20.

[0030] By installing the distribution plate 20 at the placement trough 19, the distribution plate 20 ensures that the falling coke powder is loose and evenly distributed, thereby reducing the adhesion between coke powder particles.

[0031] In an embodiment of this utility model, it further includes: a dispersing hose 21; the dispersing hose 21 is disposed inside the distributing pipe 13 and is located below the distributing disc 20.

[0032] By positioning the dispersion hose 21 below the distribution plate 20, the coke powder is further dispersed so that the vacuum pump truck can extract the coke powder.

[0033] In an embodiment of this utility model, it further includes: an air inlet pipe 22, a shut-off valve 23, and a check valve 24; the air inlet pipe 22 is connected to the distribution pipe 13; the shut-off valve 23 is disposed on the air inlet pipe 22; the check valve 24 is disposed on the air inlet pipe 22, and the check valve 24 is located between the shut-off valve 23 and the distribution pipe 13.

[0034] The air inlet ensures airflow within the connecting pipe 14 and the distribution pipe 13, allowing the air pump to extract the coke powder. The combination of the shut-off valve 23 and the check valve 24 ensures that gas can only enter the distribution pipe 13 through the air inlet, preventing the gas and coke powder in the distribution pipe 13 from flowing back to the air inlet and thus preventing backflow.

[0035] In an embodiment of this utility model, it further includes: a connecting port; the connecting port is located on one side of the distributing pipe 13, the output end of the electric distributing valve 12 passes through the connecting port and is embedded in the distributing pipe 13, and the connection port is opposite to the position of the distributing plate 20.

[0036] The material distribution plate 20 is installed inside the material distribution pipe 13 through the connecting port, and the electric sorting valve 12 is positioned opposite to the material distribution plate 20 through the connection port, so that the electric sorting valve 12 discharges coke powder to the material distribution plate 20, and the material distribution plate 20 disperses it.

[0037] In an embodiment of this utility model, the electric grid valve 12 is provided with four grid compartments.

[0038] By setting four compartments in the electric distribution valve 12, the coke powder is diverted and discharged, avoiding blockage when a large amount of coke powder is discharged at the same time, thus achieving uniform feeding.

[0039] In an embodiment of this utility model, the air pump truck connection port 16 is a quick connector.

[0040] By setting the vacuum pump truck connection port 16 as a quick connector, it can quickly connect to the vacuum pump truck's suction pipe. Furthermore, by combining the vacuum pump truck connection port 16 with the telescopic hose 15, the suction pipe can be adapted to different positions and angles, thereby improving the applicability of the device.

[0041] Implementation Process: The electric distribution valve 12 discharges the accumulated coke powder in batches from the dry quenching boiler 10. A material distribution device ensures the falling coke powder is loose and evenly distributed, reducing adhesion between particles and lowering the resistance encountered by the suction pump during extraction, thus improving ash removal efficiency. When the suction pump's extraction volume is large, but the air intake in the connecting pipe 14 is insufficient to support efficient suction, the auxiliary suction valve 17 is opened to allow a small amount of gas into the connecting pipe 14, increasing the flow rate and accelerating the extraction of coke powder. The flexible hose 15, used in conjunction with the suction pump's connection port 16, facilitates quick and easy connection to the suction pump's extraction pipe. The flexible hose 15 also adapts to different installation positions and angles, improving the flexibility of the device.
