Description
Technical field
The utility model has related to radiant tube field, has related in particular to a kind of W type heat accumulation type radiant tube.
Background technology
Gas fired radiant tubes is a kind of heater of burning gases fuel; gaseous fuel is at the radiation combustion inner pipe of sealing; by the tube-surface being heated, take heat radiation and heat is delivered to heating object as principal mode; combustion atmosphere does not contact with heating object with product; this,, just for to heat-treat the condition created under protective atmosphere, is specially adapted to product quality to require high occasion.Gas fired radiant tubes has that combustion thermal efficiency is high, stable, equipment dependability high, is widely used in various heat-treatment furnaces and continuous annealing furnace etc.
According to the cast of radiant tube, can be divided into straight pipe type, thimble tube, U-shaped, W type, Trident Type, P type, double-P type etc.No matter be the radiant tube of which kind of type, in combustion process, due to higher in flame zone flue-gas temperature, radiant heat flux density is large, and radiant tube wall temperature is higher, forms the high temperature section of radiant tube; And flue gas and radiant tube are along in journey heat transfer process after flame zone, flue-gas temperature reduces gradually, and radiant heat flux reduces, and radiant tube temperature is lower, forms the low-temperature zone of radiant tube, and the temperature distributing rule of this radiant tube has been tested and think tank confirms.Therefore inevitably cause the inhomogeneities of radiant tube surface temperature, thereby affect heating efficiency and the heating quality of radiant tube, the service life of having reduced radiant tube.
Summary of the invention
The deficiency existing for prior art, the purpose of this utility model is just to provide a kind of W type heat accumulation type radiant tube, has solved inhomogeneous, heating efficiency is poor, heating quality is poor and service life the is short problem of radiant tube surface temperature.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of W type heat accumulation type radiant tube, comprise radiant tube lid, W type body and steel pipe, and described radiant tube lid is sheathed on W type body two ends, and is installed with furnace wall inner support seat; Termination, described W type body two ends is provided with threeway flange, W type body two ends near being provided with Taper Pipe and the first short tube between termination, and this Taper Pipe interconnects with one end of the first short tube, the other end of Taper Pipe and the first short tube is connected with W type body two ends respectively; Described the first short tube is outside equipped with the second short tube, and is provided with the expansion joint of having filled heat-preservation cotton between the first short tube and the second short tube; One end of described steel pipe is connected with the side of Taper Pipe, the other end is connected with sampling and chews.
As a kind of preferred version, described W type body comprises elbow and straight tube, and this elbow is installed with connecting line support.
As a kind of preferred version, described radiant tube lid is provided with elastic ring with junction, termination, W type body one end, and this elastic ring thickness is 3mm; Radiant tube lid is connected to bearing with junction, W type body other end termination pressure-tight weld.
As a kind of preferred version, described elastic ring is positioned at one end, the bearing that W type body is provided with Taper Pipe and is positioned at one end that W type body is provided with the first short tube.
As a kind of preferred version, described the first short tube is connected by flange with the second short tube.
Compared with prior art, the beneficial effects of the utility model:
1. long because of flue gas flow path in pipe, rocket motor is many, and heat exchange effect is stronger, and exhaust gas temperature reduces, and has improved the thermal efficiency;
2. surface temperature distribution good uniformity, makes to be heated workpiece and is heated evenly, and has improved productivity ratio and product quality;
3. reduce thermal stress and the Partial ablation of radiant tube, service life of radiant tubes service life, reduced production cost;
4. ignition temperature is all evenly distributed, and there is no localized hyperthermia district; In commutation process, combustion zone suction part is delayed, and reduces combustion zone oxygen concentration, thereby contributes to suppress the generation of oxynitrides, has reduced the discharge of pollutant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Embodiment:
As shown in Figure 1, a kind of W type heat accumulation type radiant tube, comprises radiant tube lid 1, W type body 2 and steel pipe 3, and described radiant tube lid 1 is sheathed on W type body 2 two ends, and is installed with furnace wall inner support seat 4; Described W type body 2 terminations, two ends are provided with threeway flange 5, W type body 2 two ends near being provided with Taper Pipe 6 and the first short tube 7 between termination, and this Taper Pipe 6 interconnects with one end of the first short tube 7, the other end of Taper Pipe 6 and the first short tube 7 is connected with W type body 2 two ends respectively; Described the first short tube 7 is outside equipped with the second short tube 8, and is provided with the expansion joint 9 of having filled heat-preservation cotton between the first short tube 7 and the second short tube 8; One end of described steel pipe 3 is connected with the side of Taper Pipe 6, the other end is connected with sampling and chews 10; Described W type body 2 comprises elbow 11 and straight tube 12, and this elbow 11 is installed with connecting line support 13; Described radiant tube lid 1 is provided with elastic ring 14 with W type body 2 junctions, termination, one end, and these elastic ring 14 thickness are 3mm; Radiant tube lid 1 is connected to bearing 15 with W type body 2 junction, other end termination pressure-tight welds; Described elastic ring 14 is positioned at one end, the bearing 15 that W type body 2 is provided with Taper Pipe 6 and is positioned at one end that W type body 2 is provided with the first short tube 7; Described the first short tube 7 is connected by flange 16 with the second short tube 8.During concrete enforcement, burner is installed in radiant tube of the present utility model two ends, cold air and hot flue gas enter radiant tube by burner, air can be preheated to and approach radiant tube tube wall temperature, thereby the limit that realizes flue gas heat reclaims, because of flue gas flow path in pipe long, rocket motor is many, heat exchange effect is stronger, and exhaust gas temperature reduces, thereby has improved the thermal efficiency.
