A tamping coke oven riser layout structure

Abstract

The invention relates to an arrangement structure of rising pipes of a tamping coke oven. A high-pressure ammonia injection device is installed on the pipe; a tamping coal charging machine is installed on the side of the coke oven machine. The beneficial effects of the present invention are: the structure can smoothly introduce the raw coal gas generated when the tamping coke oven is charged into the gas collecting pipe and can effectively control the oxygen content of the imported raw coal gas, and has the advantages of flexible operation, convenient maintenance, reasonable structural layout, and low investment. The advantages of saving, energy saving and environmental protection are remarkable, and it can effectively guarantee the smooth progress of production. The negative pressure generated by the high-pressure ammonia water injection device on the coke side bridge pipe on the top of the coke oven quickly guides the raw gas generated when the tamping coke oven is charged into the gas collection pipe through the rising pipe and can effectively control the oxygen content of the imported raw gas. It is the best way to tamp the coke oven charging smoke and dust to escape; and to complete the normal export of the raw gas generated in the production and enter the next process.

Description

technical field [0001] The invention relates to an arrangement structure of rising pipes of a tamping coke oven, which can smoothly guide coal charging flue gas into a gas collecting pipe during coal charging, control the oxygen content of the flue gas, and complete the normal export of raw coal gas generated during production into the next process. Background technique [0002] When charging coal in tamping coke ovens at home and abroad, the riser pipes are arranged on the machine side. Since the riser pipes are arranged on the machine side, the side riser pipes are close to the completely open machine side furnace mouth during coal charging, and a large amount of complex components The smoke and dust cannot be introduced into the gas collecting pipe through the rising pipe. A large amount of air will be brought in, resulting in a high oxygen content in the gas, which will bring safety hazards to the subsequent sections. Therefore, it can only be processed by the furnace top...
