Description
Technical Field
The utility model relates to the technical field of blast furnace dust removal equipment, in particular to a dust removal system above a blast furnace tuyere.
Background
The blast furnace tuyere is used in blast furnace in iron mill, and high temperature hot blast blown in from the blast furnace tuyere and coke at the bottom of the furnace are oxidized and burnt to produce CO, which is used for reducing iron originally existing in oxide form during high temperature rise. The tuyere sleeve is arranged in the tuyere of the blast furnace, and influences the air inlet quantity of the blast furnace, so that the tuyere sleeve needs to be periodically overhauled, cleaned and replaced. When the tuyere sleeve is overhauled and replaced to clean slag iron in the tuyere, smoke dust generated by slag iron in the blast furnace can overflow through the tuyere, and generated flying dust drifts on site to pollute the site. Meanwhile, dust is harmful to respiratory organs of overhaulers, and great potential safety hazards exist. Therefore, there is an urgent need to design a dust removal system above the blast furnace tuyere to solve the problems that dust is easy to pollute the environment and potential safety hazards are easy to occur when the existing blast furnace tuyere is overhauled.
Disclosure of Invention
Aiming at the problems in the prior art, the utility model aims to provide a dust removal system above a blast furnace tuyere.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a dust pelletizing system of blast furnace tuyere top, includes dust removing mechanism and blast furnace, dust removing mechanism includes dust removal pipeline, dust removal branch pipe and dust excluding hood, and dust removal branch pipe intercommunication dust removal pipeline and dust excluding hood, the pipeline of blast furnace dust remover is connected to the dust removal pipeline, and the dust excluding hood sets up in the wind gap top of blast furnace.
Specifically, a tuyere sleeve is arranged at a tuyere of the blast furnace and is connected with a hot air surrounding pipe through a pipeline, an air supply pump is arranged on the pipeline, and the air supply pump conveys hot air of the hot air surrounding pipe into the blast furnace.
Specifically, a dust removal pneumatic valve is arranged on the dust removal branch pipe, and the blast furnace dust remover provides dust collection power of the dust removal hood.
Specifically, the dust removing pipeline is fixed on a blast furnace support through a support.
The utility model has the following beneficial effects:
the dust removing system above the blast furnace tuyere, which is designed by the utility model, provides power through the dust remover of the blast furnace, absorbs dust through the dust hood, recovers raised dust, improves the site environment, creates a good working place, reduces the potential safety hazard of overhaulers, and improves the overhauling working efficiency.
