In the rotation of the support 11, the support 11 drives the curved rod 12 to sweep circumferentially, the catalyst in the storage cavity 14 can be discharged out of the catalyst through the discharge hole 13 under the action of centrifugal force, and the catalyst can purify harmful substances in the inner part of the flue gas and prevent the flue gas from causing serious pollution to the air;
Furthermore, when the catalyst reacts with the flue gas, a lot of heat is generated in the flue gas outlet of the furnace body 1, for example, when the fuel used by the burner 2 is natural gas, the waste gas generated by the combustion of the natural gas needs to be purified by a three-way catalyst, and in the three-way catalyst, the active sites on the surface of the catalyst promote oxidation and reduction reactions of pollutants in the waste gas, and the reactions involve the formation and fracture of chemical bonds, so that certain energy is released, so that the flue gas outlet of the furnace body 1 generates a more obvious chimney effect, the negative pressure pipe 20 is subjected to a larger negative pressure, the ash suction pipe 17 has a better adsorption force, the heat in the furnace body 1 is closer to the direction of the rotary pipe 5, the heating and reaction effects of the medium in the rotary pipe 5 are further improved, and the effect of the ash suction pipe 17 sucking away the smoke dust is improved.
Furthermore, the ring gear 10 drives the roller 19 to move up and down through the plurality of cambered surface protrusions 25 at the lower end, the roller 19 knocks against the lower end surface of the ring gear 10, the ring gear 10 vibrates and transmits the vibration to the curved rod 12 and the supporting column 11, and the granular catalyst in the storage cavity 14 can be discharged from the discharge hole 13 at high temperature, so that the discharge hole 13 can be prevented from being blocked by the catalyst.
Further, the discharging directions of the plurality of discharging holes 13 are perpendicular to the axis of the furnace body 1, and since the discharging directions of the discharging holes 13 are opposite to the axis of the furnace body 1, when the discharging holes 13 discharge the catalyst and react with the flue gas, the generated energy can push the curved rod 12 to sweep circumferentially, so that the curved rod 12 more efficiently drives the ring gear 10 to rotate, and the ring gear 10 more efficiently drives the rotary pipe 5 to rotate.
This adjustable heat distribution ratio's tubular furnace, when using, through a plurality of flaming nozzles 3 on the combustor 2 to the heating of flaming in the furnace body 1, upward the flame that scurrys the top can reduce the speed of slowing down under the effect of flight 8, thereby increase the time that flame stays in furnace body 1, indirectly promote the homogeneity and the efficiency of heating pipe 4 heating, thereby make heating pipe 4 obtain more even heat distribution, and spiral flight 8 can also make the flame form the heliciform, the heliciform flame can form higher humidity and temperature gradient in furnace body 1, in this way, the combustion rate can accelerate, the fuel mixes with oxygen more fully, thereby improve combustion efficiency and heat release volume, and the area of contact between flame and the surrounding material can be increased to the rotary motion of heliciform flame, this can strengthen the heat transfer effect, improve the heat transfer rate, make the heat distribution to heating pipe 4 more even.
When the flame passes through the spiral sheet 8, the upward thrust of the flame can enable the spiral sheet 8 to drive the middle column 7 to generate autorotation, the middle column 7 can drive the support column 11 to rotate, the support column 11 can drive the ring gear 10 to rotate in the furnace body 1 through the curved rod 12, the ring gear 10 can drive the plurality of rotating pipes 5 to rotate through the plurality of driven gears 9, the rotating pipes 5 can be heated more comprehensively and uniformly by the flame, the rotating pipes 5 can heat the internal medium more uniformly, thereby the heating effect and the reaction effect of the internal medium are improved, the rotating pipes 5 can enable the internal medium to flow in the circumferential direction, the medium can be contacted with the inner wall of the rotating pipes 5 more uniformly, and the heating effect of the medium is more uniform.
In the heating process of the rotary pipe 5, part of chimney generated during flame combustion is accumulated on the outer wall of the rotary pipe 5, thereby influencing the heat conduction performance of the rotary pipe 5, indirectly influencing the heating effect of internal media, when the rotary pipe 5 rotates, the brush 18 clung to the outer wall of the rotary pipe 5 sweeps off the smoke dust of the outer wall of the rotary pipe, the heat conduction performance of the rotary pipe 5 is ensured, and when the furnace body 1 discharges smoke through the smoke outlet at the upper end, the chimney effect of the smoke outlet can suck the negative pressure pipe 20, the negative pressure pipe 20 sucks the standpipe 16 through the hose 26, the standpipe 16 sucks the smoke dust through the plurality of ash suction pipes 17, the ash suction pipes 17 can suck the smoke dust swept by the brush 18 on one hand, the outer wall of the rotary pipe 5 is prevented from being polluted again under the lifting effect of flame, the brush 18 is cleaned, the effect of continuously cleaning the smoke dust is ensured, and the other face is ensured, the sucked ash suction pipe 17 can enable the hot air in the middle of the furnace body 1 to approach the direction of the inner wall of the furnace body 1, thereby the heat quantity of the flame is more efficiently contacted with the rotary pipe 5, and the heating efficiency of the medium in the rotary pipe 5 is greatly improved.
When the ring gear 10 rotates, the ring gear 10 can drive a plurality of cambered surface convex blocks 25 to sweep circumferentially, when the cambered surface convex blocks 25 are propped against the roller 19, the roller 19 can drive the vertical pipes 16 to slide towards the supporting plate 21, when the cambered surface convex blocks 25 are over the roller 19, the reset springs 22 can drive the vertical pipes 16 and the roller 19 to move upwards for reset, the roller 19 can be propped against the lower end surface of the ring gear 10 again, then when the cambered surface convex blocks 25 sequentially pass through the roller 19, the roller 19 can drive the vertical pipes 16 to reciprocate up and down, the vertical pipes 16 can drive the ash suction pipes 17 and the brushes 18 to reciprocate up and down, so that the outer walls of the rotating pipes 5 are cleaned more comprehensively by the brushes 18, the ash suction pipes 17 can suck the cleaned dust more comprehensively, and the hot air in the middle of the furnace body 1 can be diffused more uniformly towards the periphery of the furnace body.
