Abstract
A secondary dust removal system for converters comprises a dust removal main pipe and two or more sets of converter tail end trapping devices and is characterized by further comprising a furnace rear dust removal pipe A and a dust removal pipe B which are connected through a connecting pipe, wherein the dust removal pipe A is connected with the converter tail end trapping devices; and the dust removal pipe B is connected with the dust removal main pipe in the area of dust removal equipment. According to the utility model, the two sets of dust removal pipes are connected with each other through the connecting pipe, so that dust removal air is uniformly distributed among the converters, the problem of pipe network unbalance caused when the converters share one set of secondary dust removal system is eliminated, the phenomenon that part of the converters have poor dust removal effects due to nonuniform air distribution is avoided, the operation energy consumption of the dust removal system is lowered, the dust removal efficiency is greatly improved, and the work environment of workers is improved.
Description
Technical field
The utility model relates to a kind of secondary BOF dedusting system system.
Background technology
Converter can produce a large amount of secondary smokes in process of production, the flue dust that produces during operations such as comprising hot metal charging, feed in raw material, tap and slag tap, the flue dust that when the oxygen blast smelting operation, produces and the flue dust that when oxygen blast is smelted, distributes owing to the molten steel splash.In order to guarantee ordinary production; Improve the operating environment of factory; Converter steelmaking workshop operated by rotary motion secondary BOF dedusting system system; And the shared cover final dusting system of several block converters, the reasonable Arrangement of dust excluding hood wherein, the dedusting air quantity rationally confirm and dust-removal system pipe network air quantity properly distributed is the key factor that influences the secondary BOF dedusting system effect.The dedusting house steward of existing final dusting system directly is connected with the terminal capturing device of many block converters, because the pipe network gas flow is uneven, causes the phenomenon of smoldering can occurring at the index circuit of system, and dust removing effects is bad.
The utility model content
The purpose of the utility model is to provide a kind of secondary BOF dedusting system system of good dedusting effect.
The purpose of the utility model is to realize like this; A kind of secondary BOF dedusting system system; Comprise dedusting house steward and two covers or the terminal capturing device of the above converter of two covers; It is characterized in that: dust removing tube A is connected with dust removing tube B and through pipe connecting after also comprising stove, and said dust removing tube A is connected with the terminal capturing device of converter, the total pipe coupling of dedusting in said dust removing tube B and dust removal installation zone.
In order further to eliminate the pipe network imbalance problem and to be convenient to control, above-mentioned pipe connecting is 1～4, and is equipped with the dedusting valve separately on each pipe connecting.
For better system, be convenient to operation, bring into play the ability of secondary BOF dedusting system system to greatest extent, above-mentioned dedusting valve is an adjustable gate.
In order making message feedback to be arranged each other between the above-mentioned valve, to be provided with interlocking gear between the said dedusting valve.
Above-mentioned dedusting valve is motorized valve or pneumavalve.
The terminal capturing device of above-mentioned converter comprises final dusting door type cover and the main cover of inhaling.
For easy to process, above-mentioned dust removing tube A and dust removing tube B are equal diameter pipe.
The utlity model has following beneficial effect; The utility model is provided with two cover dust removing tubes and interconnects through pipe connecting, makes the uniformly distributing between many block converters of dedusting air quantity, the pipe network imbalance problem when having eliminated the shared cover final dusting system of many block converters; Avoided because air quantity distributes the uneven bad phenomenon of segment converter dust removing effects that causes; Not only practice thrift the operation energy consumption of dust-removal system, and increased substantially efficiency of dust collection, improved workman's Working environment.
