Abstract

The invention discloses an ash removal device and a steelmaking production line. The ash removal device comprises a shell and a plurality of ash falling plates for collecting dust in high-temperatureflue gas, wherein the shell is provided with a flue gas input port and a flue gas output port; a containing cavity for containing the ash falling plates and a flue gas conveying channel for conveyingthe high-temperature flue gas are formed in the shell; the two ends of the flue gas conveying channel communicate with the end face of one side of the containing cavity and the flue gas input port correspondingly; the flue gas output port is located below the shell and communicates with the bottom of the containing cavity; the ash falling plates are arranged in the containing cavity in a layered manner from top to bottom, a gap is reserved between every two adjacent ash falling plates, and therefore a flat flue gas runner is formed between every two adjacent ash falling plates; and each ash falling plate is provided with a plurality of ash leaking holes. The ash removal device and the steelmaking production line solve the technical problem that the purification effect of converter flue gasin a high-temperature interval is poor.

Description

technical field

[0001] The present invention relates to the field of steelmaking equipment, and further relates to a soot cleaning device and a steelmaking production line, in particular to an intermittent soot cleaning device for cleaning and dedusting a steelmaking flue in an airtight space and steel production lines. Background technique

[0002] Converter oxygen blowing steelmaking is the main form of steelmaking in steel mills at present. Its main feature is intermittent periodic operation. Generally, the production cycle of each furnace of steel is 40 minutes, and the cycle operation is repeated. Among them, a large amount of gas and dust (containing a large amount of FeO, Fe 2 o 3 and CaO and other active and exothermic alkaline dust), slag and heat, etc., the temperature of these high-temperature flue gases containing dust can drop to about 800°C after passing through the movable fume hood, fixed fume hood and vaporization cooling flue. It can be transported to su...
