Problems solved by technology

[0005] The invention provides a device and method for tamping the coke oven machine side furnace door and furnace top smoke and dust, which effectively solves the problem that the furnace top smoke and machine side smoke are difficult to be exported at the same time, and the furnace top smoke and dust are connected to the interface and the machine side. The effective flow area of ​​the smoke and dust conduction interface is increased, which reduces the running resistance and reduces the running cost

Embodiment Construction

[0018] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0019] Such as Figure 1-Figure 3 As shown, a tamping coke oven machine side furnace door and furnace top smoke and dust collection device according to the present invention includes a smoke guide car 5, a lifting sleeve 10, a telescopic butt joint guide sleeve 6, a double-interface flap valve, and a connecting pipe 3 and the suction hood 4, the smoke guide car 5 moves along the furnace roof, the smoke guide car 5 is provided with a combustion chamber 11, and the bottom of the combustion chamber 11 is docked with the smoke outlet of the furnace top through a plurality of lifting sleeves 10; the combustion chamber 11 One side is docked with the lateral opening of the dual-interface flap valve through the telescopic docking guide sleeve 6; the bottom opening of the dual-interface flap valve is connected to the suction hood 4 through the connecting p...

Abstract

The invention relates to a device and method for collecting flue dust of an oven side-wall door and an oven top of a stamp charging coke oven. A dual-port flap valve group is formed after a pluralityof dual-port flap valves disposed corresponding to each carbonization chamber are communicated. A bottom opening of each dual-port flap valve is an oven side-wall flue dust connector. First self-weight fallback type flap valves are disposed in connecting pipes. A smoke guide vehicle is provided with a first hydraulic push rod used for opening the first self-weight fallback type flap valves to allow the oven side-wall flue dust connectors to be in a communicating state. A side opening of each dual-port flap valve is an oven-top flue dust connector. The side openings are provided with second self-weight fallback type flap valves. The top of a telescopic butt-joint guide sleeve is provided with a second hydraulic push rod used for opening the second self-weight fallback type flap valves to allow the oven-top flue dust connectors to be in a communicating state. The first hydraulic push rod and the second hydraulic push rod are disposed at two ends of the smoke guide vehicle respectively. The device and the method effectively overcome a problem that simultaneous discharge of oven side-wall door flue dust and oven-top flue dust is difficult. Effective communication areas of the oven side-wall flue dust connectors and the oven-top flue dust connectors are increased, thus reducing running resistance.

Description

technical field [0001] The invention relates to the technical field of coke oven smoke and dust purification, in particular to a device and method for tamping a coke oven machine side door and a furnace top smoke and dust collection. Background technique [0002] When charging coal in a tamping coke oven, there are two main ways to collect and purify the smoke emitted from the top of the furnace. One is to use a top smoke elimination vehicle or a furnace top smoke guiding vehicle to collect it, and then process it locally through a dust collector and a fan; The other is to use the crossing pipe of the smoke guide car to guide the coal charging smoke into the adjacent carbonization chamber, and cooperate with high-pressure ammonia water injection to guide part of the smoke into the coke oven gas collection pipe. These methods can only capture the smoke and dust on the top of the furnace, but there is no corresponding treatment method for the fugitive smoke and dust from the f...
