Abstract
The utility model discloses a thermal deformation compensation device for sintering equipment, which is made of rolling plates. The device comprises two identical frame structures; one side of an inner frame of one frame structure is connected with an outlet gas flue, and the other side is connected with a mutitube dedusting device; and one side of an inner frame of the other frame structure is connected with an inlet gas flue, and the other side is connected with the mutitube dedusting device. The thermal deformation compensation device disclosed by the utility model can compensate thermal deformation of a pipeline, avoid air leakage, and prolong the service life.
Description
Technical field
The utility model relates to agglomerating plant, specifically is a kind of thermal distortion compensation device for agglomerating plant (or claiming the metal compensator).
Background technique
Generally about 100-200 ℃, pressure 8-20KPa is easy to generate deposition and etching apparatus to the sintering heatrejection under the corrosive gass such as interior sulfur-containing oxide, nitrogen oxide, low temperature.When preventing in the production process that pipeline heats up, because thermal stretching or temperature stress cause pipe deforming or destruction, need compensator be set at pipeline, with the thermal stretching of compensation pipeline, thereby reduce the stress of tube wall and act on active force on the supporting structure.
In sintering machine head end dedusting both sides, generally adopt non-metallic fabrics compensator or metal bellows compensator as the compensation device of thermal distortion, be mainly used in the radial and axial distortion of exhaust column.The fabric compensator is no matter radial and axial can bigger compensation rate, but its main material is silastic fabric, under the situation of High Temperature High Pressure power, very easily produces and tears, and the compensator life-span is lower.Metal corrugation compensator adopts corrugated stainless steel tubing material by way of compensation, the thickness of stainless steel material generally only can be accomplished 0.5-1mm, at 1-2 only in sinter fume condition following working life, and the compensator of moulding is for easy for installation, often adopt flange to be connected with body, leaking out between connecting bolt and flange mouth is inevitably basically, will cause the increase of the harmful air quantity of sintering like this, thereby reduced sintering output, increased energy consumption.
Summary of the invention
The purpose of this utility model is to provide a kind of thermal distortion compensation device for agglomerating plant, makes it to compensate the thermal distortion of pipeline, can avoid again leaking out, and also can increase the service life simultaneously.
The technical solution of the utility model is: be made into (can satisfy compensation rate) thermal distortion compensation device with roll bending, this device is two identical shaped as frame structures, one side of the inside casing of one shaped as frame structure is connected with exhaust pass, another side is connected with multi-tube dusting, one side of the inside casing of another shaped as frame structure is connected with inlet flue duct, and another side is connected with multi-tube dusting.
Thermal distortion compensation device of the present utility model has following advantage:
1, can adopt the common low carbon alloyed steel as material, cheap, draw materials easily, make simply, particularly particularly like this to iron and steel enterprise.
2, can adopt the higher steel plate of thickness, generally can select δ for use is that the above steel plate of 4mm is until the steel plate of thickness a little less than person in charge's material, the working life that can greatly improve compensator like this.
3, this structure can field fabrication, fully phases out flange, directly with the two ends of roll bending be responsible for welding, in life cycle, avoid the generation of air leakage phenomena fully.Also can adopt flange to connect, it is convenient to change.
The utility model can compensate the thermal distortion of pipeline, can avoid again leaking out, and also can increase the service life simultaneously.
