Coal-charging and coke-discharging two-in-one flue dust collecting and purifying method and device of coke oven

Abstract

The invention relates to coal-charging and coke-discharging flue dust collecting and purifying device of a coke oven. A coal-charging flue dust collecting device at the machine side is used for collecting and delivering flue gas dissipated at an oven door when coal is charged, and a flue dust collecting and processing vehicle arranged on the oven top is in butt joint with a special coal-charging flue gas transmitting belt trolley to deliver flue dust dissipated at air discharging holes on the oven top; flue dust dissipated during discharging coke is collected and delivered through a coke side belt sealing air pipe arranged at the outer side of a track of a coke quenching car at the coke-discharging side of the coke oven; the flue gas dissipated at the oven door is delivered to the coke side belt sealing air pipe through a pipeline, the flue dust dissipated at the air discharging holes on the oven top is delivered into the coke side belt sealing air pipe through a gas guiding pipe, and the flue gas and the flue dust are together delivered into a ground dust removing station through a pipeline of an output port of the coke side belt sealing air pipe for purification. The device has the advantages of favorable flue dust gathering effect, high degree of the automation and convenient operation and can continuously, safely and stably run.

Description

technical field [0001] The invention relates to a two-in-one purification device for coking oven coal charging and coke discharge double air collection ground station, which is suitable for collecting and transporting smoke and dust of top-mounted and side-mounted coke ovens with different heights. Background technique [0002] For the current three-wind collection system, it is mainly used in mechanical coke ovens with a height of 4.3 meters and above. How to further expand the scope of application of the belt-type sealed air duct according to market conditions to adapt to the dust removal of coke ovens with different carbonization chamber heights. How to further reduce the cost of the project, this system is a double-air collection system developed on the basis of the improved design of the three-air system, which is more suitable for the use of mechanical coke ovens with less than 2×56 holes.

Problems solved by technology

[0003] The purpose of the technology of the present invention is to provide a two-in-one purification device for coke oven charging and coke discharge double-air collection ground station that is suitable for different heights of carbonization chambers, so as to solve the problems of complicated operation, high failure rate, inconvenient maintenance and flapping of the existing traditional technology. The cost of valves and dust collection air ducts is high, and the steel structure support of the coke delivery duct consumes a lot of steel. This system shares a set of belt ducts for coal charging and coke output, which saves cost and can also improve the furnace roof. Operator's working environment and reduce labor intensity of workers
