Description
Technical field
This utility model belongs to field of iron and steel smelting, especially relates to a kind of smoke evacuation heat ray filter of desulfurizing iron.
Background technology
Sulfur is one of impurity element in iron and steel, is the quality ensureing steel grade in steel smelting procedure, must be right before smelting
Molten iron carries out desulfurization process.The desulfurizing iron mode commonly used at present rotates stirring desulphurization method and blowing desulfurization method for agitator, front
Desulfurizing agent is incorporated in molten iron by way of stirring by person, and desulfurizing agent is then incorporated molten iron by way of air conveying by the latter
In.No matter using which kind of mode, all producing the heat loss of substantial amounts of ash-laden gas and molten iron.
The desulfurization of molten iron is carried out mostly in ladle.During desulfurizing iron, the ferrum that up to more than 1300 DEG C of upper surface
Water produces strong heat exchange with outside air and produces a large amount of ash-laden gas, and this flue gas has swept along partial desulfurization agent to dedusting system
In system；Meanwhile, in molten iron, amount of heat loses to the facility of ash-laden gas and surrounding.It follows that existing molten iron takes off
There are three aspects in sulfur mode：Firstth, a large amount of ash-laden gas increased capital expenditure and the operating cost of dust pelletizing system；
Secondth, a large amount of loss of the heat in molten iron increased smelting cost；When the 3rd, adopting agitator to rotate stirring desulphurization method, part
Desulfurizing agent is swept along to dust pelletizing system, had not only increased the burden of dust pelletizing system but also increased the use cost of desulfurizing agent.
Chinese patent ZL201520527423.9 discloses a kind of Desulfuring Device of Hot Metal saving desulfurizing agent, and this device is directed to
Agitator rotates stirring desulphurization device and is efficiently modified, and it includes being arranged on the ajutage of desulfurizing agent elephant trunk fixing pipe afterbody
Swirl-flow devices arranging with pressure fan and in desulfurizing agent elephant trunk moving tube etc., cleaned air or other non-oxygen that pressure fan is sent into
The property changed gas and the desulphurizer mixing entering elephant trunk from feed bin, mixed Dual-Phrase Distribution of Gas olid fluid, after swirl-flow devices, takes off
Sulfur agent is effectively disperseed, and is filled with the molten iron face being in rotation status with eddy flow state after overcoming the hot pressing of thermal current of rising
Tap is touched, so that desulfurizing agent is more effectively absorbed by molten iron.But the dust constaining tolerance in this patent unresolved sweetening process
The excessive heat loss problem with molten iron, is not fully solved the losing issue of desulfurizing agent yet.
For blowing desulfurization method, the excessive heat waste with molten iron of the dust constaining tolerance in also not disclosed process sweetening process
The data of mistake problem.
Utility model content
The purpose of this utility model is exactly to overcome the defect of above-mentioned prior art presence to provide one kind can reduce
Heat loss amount, minimizing desulfurizing agent use, thus the smoke evacuation heat ray filter of the desulfurizing iron of reduces cost.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of smoke evacuation heat ray filter of desulfurizing iron, is arranged in ladle, and this device includes smoke evacuation heat shield, injection takes off
Sulfur rifle or agitator rifle, lifting assembly and dedusting enclosure,
Described smoke evacuation heat shield is located at the top of ladle, and boosted assembly controls lifting, described blowing desulfurization rifle
Or agitator rifle passes through smoke evacuation heat shield to extend in ladle, described dedusting smoke evacuation is located at the top of smoke evacuation heat shield,
The flue gas of effusion from smoke evacuation heat shield can be drained.
Described smoke evacuation heat shield is truncated cone-shaped structure, and lower mouth external diameter is slightly larger than the internal diameter of ladle mouth, and upper internal diameter is big
External diameter in blowing desulfurization rifle or agitator rifle.
It is further opened with thief hole and/or the manhole appendix of desulfurizing agent elephant trunk on described smoke evacuation heat shield.
The upper end of described lifting assembly is fixedly mounted on desulfurization platform.
Described lifting assembly is by the hoist engine being sequentially connected from top to bottom, steel wire rope, suspension hook, and limit switch and electricity
Control system etc. forms, and described hoist engine is arranged on desulfurization platform.
Described hoist engine is also interlocked with blowing desulfurization rifle or agitator rifle.
Compared with prior art, this utility model has advantages below：
(1) it is provided with smoke evacuation heat ray filter on ladle top, make the heat exchange of the molten iron in ladle and outside air
Intensity substantially reduces, so that the heat loss amount of the generating capacity of ash-laden gas and molten iron is greatly reduced；Agitator is rotated and stirs
For mixing doctor treatment, the loss of desulfurizing agent also synchronously reduces.Thereby saving the capital expenditure of dust pelletizing system and operating cost and
The heat loss cost of molten iron and the use cost of desulfurizing agent.
(2) setting of smoke evacuation heat ray filter no negatively affects substantially to existing sulfur removal technology.
