Abstract
The utility model discloses a comprehensive smoke-discharging dedusting system of LF fining furnace, which is provided with the following structures that a smoke discharging hole is arranged on a furnace cover of the LF fining furnace, the furnace top is provided with a dust collecting device, the smoke discharging hole and the dust collecting device are connected to a purifying device through a pipeline, the purifying device is connected with a power device, and the power device is connected with an exhaust barrel. The comprehensive smoke-discharging dedusting system of LF fining furnace improves the dust collecting rate of a dedusting system of the LF fining furnace, can lower the installed power of the dedusting system, and reduces the influence of the dedusting system to the smelting device technology when operating.
Description
Technical field
The utility model relates to the steel-making environmental protection equipment, and specifically, the utility model is the comprehensive smoke discharging dust removing system of a kind of LF refining furnace.
Background technology
At present, LF purifying method in steelmaking process, its main characteristics is to adopt the method for ladle bottom blowing argon gas to make molten steel obtain to stir kinetic energy, and have and the same good desulfating and deoxidation effect of induction stirring, be more conducive to inclusion floating in the molten steel, because the simple and easy operation than electromagnetic mixing apparatus of ladle argon-blown technology has promoted the rapid popularization of LF technology.The used refining unit of this LF purifying method is called " LF refining furnace ".
LF refining furnace (LADLE FURNACE) is a ladle refining furnace, is external refining equipment main in the Iron and Steel Production.Its main effect is: 1. desulfurization; 2. temperature regulation; 3. accurate trimming; 4. improve the molten steel purity; 5. slag making.
The high temperature dust gas that the LF refining furnace produces in the course of the work, in order to satisfy national project construction " three simultaneously " principle, after guaranteeing that completion of project is gone into operation, the labour safety and hygiene standard that meets national regulation, ensure that laborer's safety in process of production is with healthy, necessary auxiliary construction smoke discharging dust removing system is to reduce the influence to the equipment surrounding enviroment.At present at LF refining furnace smoke discharging dust removing system, smoke catching equipment adopts single treatment facility usually, finish the capture function of the high temperature dust gas that the LF refining furnace is produced in the course of the work, but, along with the continuous increase of LF refining furnace processing power, single smoke catching treatment facility often can not satisfy the needs of collecting dusty gas.
The utility model content
The purpose of this utility model provides the comprehensive smoke discharging dust removing system of a kind of LF refining furnace.
In order to realize above-mentioned utility model purpose, the utility model by the following technical solutions:
The comprehensive smoke discharging dust removing system of a kind of LF refining furnace, has following structure: cover at the LF refining furnace and be provided with smoke outlet, furnace roof is provided with smoke catching equipment, this smoke outlet and smoke catching equipment arrive treating plant by pipe connection, treating plant is connected with power-equipment, and power-equipment is connected with aiutage.
Described treating plant is long bag pulsed jet cloth filter.This fly-ash separator can effectively filter the dust in the dusty gas.
Described treating plant can also be connected with defeated dust unloadnig apparatus structure, is used to collect and concentrates the grey shape thing that transports after the purifying treatment.
Described power-equipment is preferably placed between treating plant and the aiutage.
During this dust-removal system work, the high temperature dust gas that produces during the work of LF refining furnace enters treating plant through smoke catching equipment, pipe conveying equipment and carries out the separation of dirt gas under the effect of power-equipment, isolated dust is by the defeated dust unloadnig apparatus structure centralized collection and the discharging for the treatment of plant, and clean air enters atmosphere by aiutage.
The utility model is the dust arrestment rate that the comprehensive smoke discharging dust removing system of LF refining furnace has improved LF refining furnace dust-removal system, can reduce the installed power of dust-removal system, when reducing the dust-removal system operation to the influence of smelting equipment technology.In actual motion, have the following advantages:
In the LF refining furnace smoke discharging dust removing system described in the utility model, smoke catching equipment has made full use of the advantage of interior fume collection equipment of stove and the outer fume collection equipment of stove, and in conjunction with LF refining furnace smelting technology require and flue dust a situation arises, appropriate design is arranged the capture function of finishing the high temperature dust gas that the LF refining furnace is produced in the course of the work jointly, institute of system required airflow is between above-mentioned two kinds of designs, at LF refining furnace smoke outlet everywhere in micro-vacuum state, avoided the interior fume exhaust system of stove that the influence in the requirement of LF refining furnace smelting technology has been reduced the required exhausting amount of system simultaneously, effectively reduce the initial outlay cost and the equipment operation maintenance handling cost of LF refining furnace smoke discharging dust removing system, economical and energy saving is specially adapted to the smoke evacuation dedusting of LF refining furnace more than 50 tons.
