Abstract

The invention relates to the technical field of blast furnace cooling, and particularly discloses a cooling water channel system and a maintenance method thereof. The system is applied to a cooling water channel of a blast furnace tuyere sleeve and comprises a water inlet pipeline, a water outlet pipeline for draining water and a cleaning module comprising a cleaning pipeline, the upstream of the cooling water channel is sequentially communicated with a water inlet control valve and water supply equipment through a water inlet pipeline; the water inlet control valve is used for controlling the flow of the water supply equipment; the downstream of the cooling water channel selectively communicates with the water outlet pipeline or the cleaning pipeline, the cleaning pipeline can selectively drain water, the cleaning pipeline sequentially communicates with a water supply assembly control valve and a high-pressure water supply assembly, and the water supply assembly control valve is used for controlling the flow of the high-pressure water supply assembly. By means of the structure, cleaning operation of the cooling water channel and replacement operation of the water inlet pipeline and the water outlet pipeline can be completed by changing the water flowing path in the cooling water channel under the condition that the cooling water channel runs, maintenance efficiency is improved, and production loss is reduced.

Description

technical field [0001] The invention relates to the technical field of blast furnace cooling, in particular to a cooling water channel system and a maintenance method thereof. Background technique [0002] In the process of blast furnace production, the enhanced cooling of the tuyere area is very important, especially the cooling effect of the middle and small jackets of the blast furnace directly affects the production safety of the blast furnace. [0003] In the daily production process, due to the water quality of the blast furnace, the middle and small sleeves of the blast furnace are often blocked by foreign objects in the cavity, resulting in a smaller amount of water entering and leaving the furnace and a decrease in the cooling intensity of the tuyere area. Once the water inlet and outlet at the middle or small casing is lower than the corresponding safety control standard, the blast furnace will be forced to shut down, which will result in loss of output and increas...
