Steelmaking converter flue with ash deposition prevention structure

Abstract

The invention discloses a steelmaking converter flue with an ash deposition prevention structure, and belongs to the technical field of converter flues, and the steelmaking converter flue is technically characterized by comprising a smoke exhaust pipe and a driving mechanism, spraying assemblies are arranged inside and outside the smoke exhaust pipe, filtering assemblies are arranged inside and outside the smoke exhaust pipe, eight supporting rods are mounted on the driving mechanism, and each supporting rod is provided with a dust deposition prevention structure. Four cleaning brush plates are installed on the eight supporting rods, the outer sides of the four cleaning brush plates make contact with the inner wall of a smoke exhaust pipe, the front section of the smoke exhaust pipe is in a V shape, and a collecting barrel communicating with the smoke exhaust pipe is installed on the outer side of the smoke exhaust pipe. According to the smoke exhaust pipe, dust particles in smoke can be conveniently filtered and discharged out of the smoke exhaust pipe, manual operation of workers is not needed in the whole process, meanwhile, the interior of the smoke exhaust pipe can be actively cleaned, the dust accumulation phenomenon is reduced, the smoke channel blocking phenomenon is not likely to happen, and the using effect of the smoke channel is guaranteed.

Description

technical field [0001] The invention relates to the field of steel-making converter flue, in particular to a steel-making converter flue with an anti-dust structure. Background technique [0002] The steelmaking process needs to be supplied with sufficient energy to complete. These energy sources mainly include coke, electricity, oxygen, inert gas, compressed air, gas, steam, water, etc.; the steelmaking process also releases some energy, including gas, steam, etc. When the consumed energy is less than the recovered energy, it is called negative energy steelmaking. [0003] The steam generated by converter steelmaking accounts for more than 30% of the energy gain, so increasing steam production is an important way to realize negative energy steelmaking. The high-temperature flue gas emitted by the converter is 1900-2100 ℃, and the dust content of the flue gas is about 150g / Nm³. In order to recover the converter gas and avoid the direct discharge of the flue gas from affecti...

Problems solved by technology

[0005] Because a large amount of smoke and dust are discharged through the flue, and after the flue is used for a long time, the ash will remain in the flue to form an ash layer, which will cause the blockage of the flue and affect the use of the converter. At the same time, the existing In the technology, the filter device is usually used to filter the smoke and dust, but in order to ensure the filtering effect, the staff needs to disassemble and clean it regularly, which is inconvenient and the effect of preventing dust accumulation is general. Therefore, we propose a filter with an anti-dust structure. Steelmaking converter flue to solve such problems
