[0002] Coke oven coke interception equipment is usually used in smelting or steelmaking industries, mainly for collecting and processing coke from blast furnaces or other smelting furnaces. Coke interception refers to the process of collecting coke from blast furnaces. Coke is an important smelting raw material in the blast furnace production process, used to reduce iron oxide in iron ore. Coke interception is usually carried out by coke interception vehicles. The furnace door needs to be opened during the coke interception process. The flue gas generated by the open furnace door will pollute the environment. Therefore, a smoke exhaust pipe is installed above the furnace door, which can be connected to the dust removal equipment installed on the coke interception vehicle to facilitate the purification of the flue gas and complete the purpose of dust removal during the coke interception process.
