Background

Generally speaking, the smoke guide vehicle is one of the most important dust removing devices in the production process of the coke oven. The smoke guide car is provided with a guide sleeve which is used for communicating with adjacent carbonization chambers of the coke oven so as to guide the raw gas and the smoke gas containing coal dust generated in the carbonization chamber into other carbonization chambers which are adjacent to the carbonization chambers and are in the later coking stage when coal is charged, thereby playing the role of smoke guide.

Generally, after the smoke guide vehicle finishes smoke guide, the smoke guide hole of the coke oven and the furnace cover of the smoke guide hole can be sealed, then the guide sleeve is completely lifted, and then the smoke guide vehicle starts. However, the existing smoke guiding vehicle has a common defect that after the furnace cover is covered, the whole tube of yellow smoke still exists in the guide sleeve, and after the guide sleeve is lifted, the yellow smoke overflows along with the yellow smoke, so that the surrounding environment is polluted.

Therefore, there is a need in the art for a dust collection system for removing smoke dust in a guide sleeve of a smoke guide vehicle and a smoke guide vehicle comprising the dust collection system, which can collect smoke dust such as yellow smoke remaining in the guide sleeve after each smoke guide, and then specially process and discharge the smoke dust to prevent the smoke dust from polluting the surrounding environment, thereby reducing the pollution of the smoke guide vehicle link to the surrounding environment in the production process of a coke-oven plant.

5. The system of claim 4, wherein the stationary duct system further comprises a control valve mounted at a suitable location on the manifold for controllably shutting off and opening the manifold so that the system is controllably shut off and opened.

6. The system of claim 5, wherein the control valve is a pneumatic butterfly valve.

7. The system of claim 5, wherein the stationary duct system further comprises a burst disk disposed at the top of the manifold and upstream of the control valve, and a pressure relief hole disposed on the wall of the manifold and covered by the burst disk, wherein the burst disk auto-detonates upon the entry of air into the system, such that smoke and air in the system are exhausted from the pressure relief hole.

8. The dusting system for removing smoke from the guide sleeve of a smoke guide vehicle of claim 7 where the burst disk and the pressure relief vent are each positioned adjacent the junction between the upstream and downstream portions of the stationary duct body.

9. The system of claim 7, wherein the telescoping end of the telescoping tube is removably connected to the interface end of the interface section.

10. The system of claim 9, wherein the telescoping end of the telescoping tube is connected to the interface end of the interface portion by a flange.

11. The suction system for removing smoke from a guide sleeve of a smoke guide car as set forth in claim 9, wherein the negative pressure receiving means comprises a dust trunk for receiving smoke discharged from the mouth end of the butt joint portion and treating the smoke, and a negative pressure source connected to the dust trunk, the dust trunk being provided at a position opposite to the mouth end of the butt joint portion with a receiving hole, and a hinge cover for opening and closing the receiving hole, the hinge cover being hingedly mounted to a side of the receiving hole remote from the movable butt joint portion.

12. The system of claim 11, wherein the mobile docking station further comprises:

the cover opening mechanism comprises a push rod extending towards the dust removing main pipe along the horizontal direction and a cover opening driving device used for horizontally moving the push rod, wherein the push rod is provided with a hook-shaped part at the tail end close to the dust removing main pipe, the push rod is driven by the cover opening driving device to horizontally move towards the dust removing main pipe so that the hook-shaped part contacts and opens the hinged cover of the dust removing main pipe before the discharge port end of the butt joint part is in butt joint with the receiving hole of the dust removing main pipe in a sealing mode, and the push rod is driven by the cover opening driving device to be away from the dust removing main pipe so that the hook-shaped part is separated from the hinged cover of the dust removing main pipe after the discharge port end of the butt joint part is separated from the receiving hole of the dust removing main pipe, so that the hinged cover;

the translation trolley comprises a trolley main body which is detachably mounted on the smoke guide trolley and a translation driving device for driving the trolley main body to translate, the telescopic pipe barrel is rigidly connected to the trolley main body, and the butt joint part is also rigidly connected to the trolley main body, so that when the trolley main body translates through the driving of the translation driving device, the butt joint part and the telescopic pipe barrel are driven to translate together, and the opening end of the butt joint part is in butt joint with or separated from the receiving hole of the dust removing main pipe in a sealing mode.
