Maintenance process of coke oven ascension pipes

Abstract

The invention provides a maintenance process of coke oven ascension pipes. The maintenance process specifically comprises the following steps: performing preparation; opening a water seal cover of anascension pipe, opening a coal loading hole cover far away from the ascension pipe, installing an fire guiding tool on a coal loading hole, installing heat insulation blankets on two sides of the ascension pipe, introducing compressed air through a fire observation hole for pressing the fire, disassembling base bricks of the base of the ascension pipe, disassembling a bridge pipe filler, disassembling an ammonia water pipe on the bridge pipe; disassembling an ascension pipe top platform, an ascension pipe support and other related components, hoisting the whole ascension pipe to the ground, installing a fire blocking tool of the ascension pipe at the position where the ascension pipe is located before the hoisting, repairing the ascending pipe, the bridge pipe, a water seal, repairing thebridge pipe, the water seal and the like by using spare parts on the ground, assembling the ascension pipe, enabling the furnace repairing workers to clean up the rubbish in the base of the ascensionpipe, preparing pouring materials and bridge pipe filler, and performing reassembling.

Description

technical field [0001] The invention belongs to the field of heating, and relates to a coke oven, in particular to a maintenance process for a riser pipe of the coke oven. Background technique [0002] The rising pipe is installed on the top of the coke oven, and is used to lead out the coke oven process equipment for carbonizing the raw gas in the chamber. Taking Baosteel as an example, 200 sets of rising pipes are arranged side by side on the top of each coke oven next to the coke pusher, including a base, three risers, and the top is connected to the water seal, and the side is connected to the bridge pipe and gas collecting pipe. Due to the normal production in the construction area, frequent movement of coal loading trucks and coke pushing trucks, high temperature, heavy dust, and lack of gas, smoke, dust, and exhaust gas leak when the riser pipe is damaged, causing serious environmental pollution. riser tube. Since the online replacement of riser pipes involves produ...
