Description

Technical Field

[0001] The utility model belongs to the technical field of coke oven production, and particularly relates to a smoke guiding structure on the top of a smoke guiding vehicle for a coke oven. Background Art

[0002] In the coking field, the overflow of coke oven gas and soot during the coal charging process, as well as the emission of soot during the coke discharging process, are the main pollution sources in coke oven production. Most current coke oven top smoke guiding systems use a smoke guiding vehicle on the top of the oven. The smoke guiding vehicle is connected to the smoke guiding holes at the top of the carbonization chamber through a smoke guiding sleeve arranged at the bottom of the smoke guiding vehicle on the top of the oven. A smoke guiding hole seat is provided at the smoke guiding hole, and it is closed by a smoke guiding hole cover when not guiding smoke. After retrieval, for a smoke guiding sleeve on the top of a coke oven with the patent number "201921254956.9", the beneficial effect is that a liquid seal structure is arranged on the smoke guiding sleeve connected to the coke oven machinery on the top of the oven, which can not only effectively avoid the leakage of flue gas during the smoke guiding alignment operation, but also prevent the steam generated after the liquid medium in the liquid seal structure is heated from entering the carbonization chamber and causing adverse effects on the normal production of the coke oven:

[0003] However, the temperature during the operation of the coke oven is very high, which causes the liquid seal structure (usually water) between the upper sleeve and the lower sleeve to quickly evaporate. As a result, when the water level of the liquid seal structure decreases, it cannot achieve an effective sealing effect. At the same time, after the water level of the liquid seal structure decreases, it is impossible to effectively add water. Although this patent improves the sealing performance, the inability to add water later will seriously affect the water tightness and lead to poor practicability. Summary of the Utility Model

[0020] Please refer to Figures 1-3 , the docking sleeve 3 is connected to the lifting system at the bottom end of the smoke guiding vehicle through a flange. Three main smoke guiding sleeves 1 and docking sleeves 3 are provided and correspond to the top and bottom ends of the connecting sleeve 2 one by one. Through the setting of the three main smoke guiding sleeves 1 and docking sleeves 3, the docking of the smoke guiding structure with the lifting system at the bottom end of the smoke guiding vehicle is more stable, and at the same time, the three main smoke guiding sleeves 1 improve the smoke guiding efficiency.

[0021] Please refer to Figures 1-3 , the sealing block 7 is of a hollow structure. The main smoke guiding sleeve 1 forms a sealed connection with the smoke guiding hole 11 through the wedge-shaped block 6. Through the use of the sealing block 7, a watertight connection is formed between the sealing block 7 and the smoke guiding hole 11 through a water pipe 9 to reduce the dispersion of smoke.

[0022] Please refer to Figures 1-3 , the electromagnetic valves 4 are all assembled inside the main smoke guiding sleeve 1. The controller 5 is electrically connected to the electromagnetic valves 4, and the controller 5 is connected to the control system of the smoke guiding vehicle. By connecting the controller 5 to the control system of the smoke guiding vehicle, it is convenient for the staff to control the opening of the electromagnetic valves 4, thereby improving the operation convenience of the smoke guiding structure.

[0023] Please refer to Figures 1-3 , the watertight assembly includes a water tank 8, a water pipe 9, and a water pump 10. The water tank 8 is installed on the front surface of the connecting sleeve 2, the water pump 10 is installed inside the water tank 8, a water injection port is provided on the surface of the water tank 8, the water pipe 9 is connected to the water outlet end of the water pump 10 and is connected to the sealing block 7 respectively through a three-way connecting pipe. Through the use of the watertight assembly, the watertight assembly improves the sealing performance of the smoke guiding structure during smoke guiding to prevent the dispersion of smoke.

[0024] Please refer to Figures 1-3, a watertight connection is formed between the sealing block 7 and the smoke guide hole 11 through the water pipe 9. By forming a watertight connection between the sealing block 7, the water pipe 9 and the smoke guide hole 11, the clear water in the water pipe 9 can flow into the opening at the top of the smoke guide hole 11 through the sealing block 7, thereby preventing the emission of smoke by the clear water.

[0025] Please refer to Figures 1-3 , the water pump 10 is connected to the control system of the smoke guide vehicle. By connecting the water pump 10 to the control system of the smoke guide vehicle, it is convenient for the staff to start the water pump 10 through the control system of the smoke guide vehicle for operation.

[0026] Specific working principle: As Figures 1-3 shown, when using the smoke guide structure on the top of the oven of the smoke guide vehicle, first, the smoke guide structure is docked with the lifting system at the bottom of the smoke guide vehicle. Then, when it is necessary to guide the smoke from the coke oven, the staff controls the lifting system of the smoke guide vehicle to descend, so that the main smoke guide sleeve 1 is docked with the smoke guide hole 11. At this time, the wedge block 6 is clamped with the inner wall of the smoke guide hole 11. Then, the sealing block 7 is placed into the opening at the top of the smoke guide hole 11. Next, the water pump 10 is started through the control system of the smoke guide vehicle, so that the clear water in the water tank 8 flows into the water pipe 9 through the water pump 10. Then, the clear water flows along the water pipe 9 to the sealing block 7. Then, the clear water flows along the cavity of the sealing block 7 to the opening at the top of the smoke guide hole 11 for watertightness. At the same time, the controller 5 is controlled by the control system of the smoke guide vehicle to open the solenoid valve 4, so that the smoke is poured into the smoke guide vehicle for filtration. After the water level in the water tank 8 drops, the inside of the water tank 8 is filled with water through the water injection port, so that the watertightness is not weakened due to the influence of the hot gas of the coke oven, and at the same time, the practicability of the smoke guide structure is improved. Then, the cooperation between the solenoid valve 4, the controller 5 and the control system of the smoke guide vehicle facilitates the opening of the main smoke guide sleeve 1 for guiding the smoke. Then, the wedge block 6 further improves the sealing performance with the smoke guide hole 11. This is the characteristic of the smoke guide structure on the top of the oven of the smoke guide vehicle.
