Abstract
The invention relates to a flue gas vacuum insulation tube for a submerged arc furnace. The flue gas vacuum insulation tube comprises a steel tube main body, wherein a vacuum cavity is arranged in the tube wall of the steel tube main body; the shape of the vacuum cavity corresponds to that of the steel tube main body; an annular embedding groove is formed in one end of the tube wall of the steel tube main body, and an annular embedding arm is arranged at the other end of the tube wall of the steel tube main body; the outer diameter of the annular embedding arm corresponds to the inner diameter of the annular embedding groove; the thickness of the annular embedding arm corresponds to the width of the annular embedding groove.
Description
Technical field
The present invention relates to pipeline heat-insulating technology field, particularly a kind of mineral heating furnace flue vacuum heat-preserving tube.
Background technique
The simple thermal insulating material of the many employings of existing mineral heating furnace flue insulation pipe carries out pipe insulation, because thermal insulating material does not possess intensity, in long running, can occur that pipeline is inhaled flat; Coming off due to thermal insulating material, reduces flue-gas temperature, fume afterheat generating efficiency is obviously reduced simultaneously.
Summary of the invention
In view of this, be necessary to provide a kind of high insulating effect and the mineral heating furnace flue vacuum heat-preserving tube of long service life.
A kind of mineral heating furnace flue vacuum heat-preserving tube, comprise steel pipe main body, vacuum cavity is provided with in the tube wall of steel pipe main body, the shape of vacuum cavity is corresponding with the shape of steel pipe main body, one end of the tube wall of steel pipe main body is provided with annular embedded groove, the other end of the tube wall of steel pipe main body is provided with annular and embeds arm, and the external diameter that annular embeds arm is corresponding with the internal diameter of annular embedded groove, and the thickness that annular embeds arm is corresponding with the width of annular embedded groove.
Preferably, the outer wall of annular embedding arm is provided with adiabatic gum collecting circular groove, the outer side wall of annular embedded groove is arranged adiabatic gum collecting circular groove, the tube wall of steel pipe main body is provided with adiabatic gum hand-hole, adiabatic gum hand-hole is accommodated circular groove with the adiabatic gum on the outer side wall of annular embedded groove and is communicated with.
Above-mentioned mineral heating furnace flue vacuum heat-preserving tube, vacuum cavity is provided with in the tube wall of steel pipe main body, the shape of vacuum cavity is corresponding with the shape of steel pipe main body, so can ensure that pipeline outer wall temperature (under normal temperature state) is lower than 50 DEG C, effectively can ensure that the flue-gas temperature in mineral heating furnace flue vacuum heat-preserving tube can not reduce, simultaneously, because mineral heating furnace flue vacuum heat-preserving tube is steel design, ensure that the thermal insulation layer people in running after having constructed can enter in pipeline and carry out inspection deashing, and do not trampled on breakage, the working life of thermal insulation layer reaches more than 10 years.
Accompanying drawing explanation
Accompanying drawing 1 is the cross-sectional view of the mineral heating furnace flue vacuum heat-preserving tube of a better embodiment.
Accompanying drawing 2 is the mineral heating furnace flue vacuum heat-preserving tube scheme of installation in Fig. 1.
