Detailed implementation mode

[0040] The following is a further detailed description of the present application in conjunction with the attached Figures 1-5 drawings.

[0041] An embodiment of the present application discloses a heating furnace for carbon disulfide production. Refer to Figure 1 and Figure 2 , a heating furnace for carbon disulfide production includes a furnace body 1, a sulfur supply component 2, a methane supply component 3, a mixing component 4 and an exhaust component 5.

[0042] Specifically, refer to Figure 2 , the furnace body 1 includes an outer furnace box body 11, an inner furnace box body 12 and a support pipe 13. The inner furnace box body 12 is located inside the outer furnace box body 11. The support pipe 13 penetrates through the outer furnace box body 11 and the inner furnace box body 12, and the support pipe 13 is respectively rotatably connected to the outer furnace box body 11 and the inner furnace box body 12.

[0043] Among them, four rotating grooves are opened on the outer wall of the support pipe 13. The top and bottom ends of the outer furnace box body 11 are respectively clamped in two of the rotating grooves, thereby forming a rotating connection structure between the support pipe 13 and the outer furnace box body 11; the top and bottom ends of the inner furnace box body 12 are respectively clamped in the other two rotating grooves, thereby forming a rotating connection structure between the support pipe 13 and the inner furnace box body 12.

[0044] Specifically, refer to Figure 2, The sulfur supply component 2 can supply gaseous sulfur into the inner furnace body 12. The sulfur supply component 2 includes a combustion chamber 21, a liquid sulfur pipe 22, and a nozzle 23. The combustion chamber 21 is arranged on one side of the outer furnace body 11 and is used for burning methane gas. The combustion chamber 21 is communicated with a first flue gas pipe 211. The first flue gas pipe 211 is communicated with one end of the support pipe 13. The connection part of the first flue gas pipe 211 and the support pipe 13 is rotationally connected. The support pipe 13 can rotate relative to the first flue gas pipe 211. The first flue gas pipe 211 is used to let the methane combustion flue gas enter into the support pipe 13 to provide heat inside the inner furnace body 12. Using the waste heat of the methane combustion flue gas as a heat source can reduce the energy consumption of the heating furnace.

[0045] The liquid sulfur pipe 22 is fixedly penetrated through the combustion chamber 21 and is communicated with the side wall of the outer furnace body 11. The liquid sulfur pipe 22 is used to introduce liquid sulfur. The liquid sulfur vaporizes into gaseous sulfur when passing through the combustion chamber 21. The gaseous sulfur flows into the space between the outer furnace body 11 and the inner furnace body 12 to provide heat inside the inner furnace body 12. Using the waste heat of the gaseous sulfur as a heat source can reduce the energy consumption of the heating furnace. There are two groups of nozzles 23, and the number of each group of nozzles 23 is multiple. The two groups of nozzles 23 are respectively communicated with the top and the bottom of the inner furnace body 12. The nozzle 23 is used to spray the gaseous sulfur into the inner furnace body 12. The gaseous sulfur is easier to diffuse, so it is easy to improve the mixing degree.

[0046] Specifically, referring to Figure 2 and Figure 3 , the methane supply component 3 is used to supply methane gas into the rotatable inner furnace body 12. The methane supply component 3 includes a methane gas pipe 31, a transfer part 32, a connecting pipe 33, and a mixing plate 34. The methane gas pipe 31 is fixedly penetrated through the outer furnace body 11 and is connected with the transfer part 32. The methane gas pipe 31 is used to introduce methane gas. The transfer part 32 is arranged on the inner furnace body 12. There are three connecting pipes 33 and three mixing plates 34, and they correspond one by one. One end of the connecting pipe 33 is connected with the transfer part 32, and the other end is communicated with the hollow mixing plate 34 inside. The mixing plate 34 is connected with the support pipe 13. A plurality of spray holes 341 are formed on the mixing plate 34. The spray holes 341 are used to spray the methane gas into the inner furnace body 12. The support pipe 13 can drive the mixing plate 34 to rotate with itself, so that in addition to spraying methane gas, the mixing plate 34 can also stir and mix the methane gas and the gaseous sulfur.

[0047] Among them, the transfer part 32 is used to keep the methane gas pipe 31 stationary when the inner furnace body 12 rotates. The transfer part 32 is used to make the connecting pipe 33 and the mixing plate 34 rotate with the support pipe 13. The methane gas in the methane gas pipe 31 enters into the connecting pipe 33 through the transfer part 32.

[0048] Referring to Figure 2, the mixing component 4 is connected to the inner furnace body 12 and the support pipe 13. The mixing component 4 is used to drive the rotation of the inner furnace body 12 by means of the impulse formed by the vaporization of liquid sulfur, and the mixing component 4 is used to drive the rotation of the support pipe 13 by means of the impulse of the methane combustion flue gas. The rotation direction of the support pipe 13 is opposite to that of the inner furnace body 12. The rotation of the inner furnace body 12 can make the gaseous sulfur flow into the inner furnace body 12 more evenly, and the rotation of the support pipe 13 can make the methane gas flow into the inner furnace body 12 more evenly. At the same time, the support pipe 13 driving the mixing plate 34 can also mix and stir the methane gas and the gaseous sulfur.

[0049] The exhaust component 5 is arranged on the support pipe 13. The exhaust component 5 is used to make the mixed gas after reaction in the inner furnace body 12 be continuously heated by the methane combustion flue gas in the support pipe 13 during the discharging process, so that the mixed gas continues to react.

[0050] During use, liquid sulfur is introduced into the liquid sulfur pipe 22. When the liquid sulfur flows to the combustion chamber 21, it is vaporized by heat. The gaseous sulfur flows into the space between the outer furnace body 11 and the inner furnace body 12, and then is sprayed into the inner furnace body 12 from the nozzle 23. On the one hand, the gaseous sulfur uses the waste heat to provide heat to the inside of the inner furnace body 12, and on the other hand, it is beneficial to mix inside the inner furnace body 12; the mixing component 4 drives the rotation of the inner furnace body 12 by means of the impulse of the liquid sulfur vaporization, so that the gaseous sulfur can be evenly introduced into the inner furnace body 12 during the rotation of the inner furnace body 12; the methane combustion flue gas in the combustion chamber 21 is introduced into the support pipe 13 from the first flue gas pipe 211. The methane combustion flue gas passes through the support pipe 13 to provide heat to the inner furnace body 12. The waste heat of the gaseous sulfur and the methane combustion flue gas reduces the energy consumption of the heating furnace; the mixing component 4 drives the rotation of the support pipe 13 by means of the impulse of the methane combustion flue gas, so that the support pipe 13 can drive the mixing plate 34 to stir the gaseous sulfur and the methane gas, and also makes the methane gas evenly flow into the inner furnace body 12 during the rotation of the mixing plate 34; the exhaust component 5 can make the mixed gas after the reaction of the gaseous sulfur and the methane gas continue to be heated and react by means of the waste heat of the methane combustion flue gas, improving the output of carbon disulfide; thus, by evenly introducing the gaseous sulfur and the methane gas and by stirring the gaseous sulfur and the methane gas by the mixing plate 34, the mixing degree of sulfur and methane can be improved. With the function of the exhaust component 5 to continue to react the mixed gas, the output of carbon disulfide can be increased, which is beneficial to the efficient production of carbon disulfide.

[0051] Specifically, refer to Figure 2, the mixing component 4 includes rotating blades 41. A plurality of rotating blades 41 are provided and are all fixedly connected to the outer wall of the inner furnace body 12. The plurality of rotating blades 41 are arranged around the rotation axis of the inner furnace body 12. The connection between the liquid sulfur pipe 22 and the outer furnace body 11 is directly opposite to at least one rotating blade 41. When the sulfur gas flow in the liquid sulfur pipe 22 blows on the rotating blade 41, the rotating blade 41 drives the inner furnace body 12 to rotate.

[0052] When the vaporized gaseous sulfur is introduced into the outer furnace body 11 and the inner furnace body 12, the gaseous sulfur can impact on the rotating blade 41, so that the rotating blade 41 drives the inner furnace body 12 to rotate, enabling the rotation of the inner furnace body 12 to be realized by means of the impact force of the gaseous sulfur.

[0053] Further, referring to Figure 2 , the mixing component 4 further includes driving fan blades 42. A plurality of driving fan blades 42 are provided and are all fixedly connected to one end of the support pipe 13 close to the first flue gas pipe 211. The plurality of driving fan blades 42 are arranged around the rotation axis of the support pipe 13. When the methane combustion flue gas in the first flue gas pipe 211 impacts on the driving fan blades 42, the driving fan blades 42 drive the support pipe 13 to rotate.

[0054] When the methane combustion flue gas is introduced into the support pipe 13, the methane combustion flue gas can impact on the driving fan blades 42, and the driving fan blades 42 can drive the support pipe 13 to rotate, enabling the rotation of the support pipe 13 to be realized by means of the impact force of the methane combustion flue gas.

[0055] Referring to Figure 2 , in order to realize the function of the transfer part 32, the inner furnace body 12 includes an upper box body 121 and a lower box body 122, and there is a gap between the upper box body 121 and the lower box body 122.

[0056] Specifically, referring to Figure 3 , the transfer part 32 includes connecting ring plates 321, communicating cylinders 322 and rotating cylinders 323. Two connecting ring plates 321 are arranged opposite to each other. Both of the two connecting ring plates 321 are arranged between the upper box body 121 and the lower box body 122. The two connecting ring plates 321 are respectively fixedly connected to the upper box body 121 and the lower box body 122. A connecting rod 3211 is fixedly connected between the two connecting ring plates 321. The number of the connecting rods 3211 is multiple, and the connecting rods 3211 are used to synchronously rotate the upper box body 121 and the lower box body 122.

[0057] The connecting cylinder 322 is sleeved on two connecting ring plates 321 and is rotatably connected to both of the two connecting ring plates 321. The methane gas pipe 31 is connected to the connecting cylinder 322. Both of the two connecting ring plates 321 are sleeved on the rotating cylinder 323, and the rotating cylinder 323 is rotatably connected to both of the two connecting ring plates 321. The connecting pipe 33 is connected to the rotating cylinder 323. The two connecting ring plates 321, the connecting cylinder 322 and the rotating cylinder 323 jointly enclose an annular closed space, and the methane gas in the methane gas pipe 31 can flow into the connecting pipe 33 through the annular closed space.

[0058] Under the action of the connecting cylinder 322, the methane gas pipe 31 can remain stationary when the inner furnace body 12 rotates, so that the methane gas pipe 31 can stably transport methane gas into the annular closed space. Under the action of the rotating cylinder 323, the connecting pipe 33 and the mixing plate 34 can rotate following the support pipe 13, so that the mixing plate 34 can stir the gaseous sulfur and methane gas. Under the cooperation of the connecting cylinder 322 and the rotating cylinder 323, the methane gas can be introduced into the inner furnace body 12 when the inner furnace body 12 rotates.

[0059] Refer to Figure 3 , in order to improve the mixing effect of the mixing plate 34, the connecting pipe 33 is rotatably connected to the rotating cylinder 323, the mixing plate 34 is rotatably connected to the support pipe 13. The mixing assembly 4 further includes a bevel gear ring 43 and bevel gears 44. The bevel gear ring 43 is fixedly connected to the inner furnace body 12. There are three bevel gears 44, which correspond to the connecting pipes 33 one by one. The bevel gears 44 are fixedly connected to the connecting pipes 33, and the bevel gears 44 are meshed with the bevel gear ring 43.

[0060] When the support pipe 13 drives the connecting pipe 33 and the mixing plate 34 to rotate, the bevel gears 44 connected to the connecting pipe 33 can rotate under the drive of the bevel gear ring 43. The bevel gears 44 drive the connecting pipe 33 to rotate, and the connecting pipe 33 can drive the mixing plate 34 to turn over, so that the mixing plate 34 can also turn over the gaseous sulfur and methane gas when stirring the gaseous sulfur and methane gas, improving the mixing effect of the mixing plate 34.

[0061] Refer to Figure 2 , in order to drive the gaseous sulfur to actively flow towards the methane gas, the mixing assembly 4 further includes guide vanes 45. There are two groups of guide vanes 45, and both are located inside the inner furnace body 12. Both groups of guide vanes 45 are fixedly connected to the support pipe 13 and are respectively located on both sides of the mixing plate 34. The number of each group of guide vanes 45 is three, and each group of guide vanes 45 is arranged around the rotation axis of the support pipe 13. Both groups of guide vanes 45 are used to make the gaseous sulfur flow towards the mixing plate 34 when rotating following the support pipe 13.

[0062] When the support pipe 13 drives the mixing plate 34 to rotate, the support pipe 13 can synchronously drive the two groups of guide vanes 45 to rotate. The airflow formed by the rotation of the two groups of guide vanes 45 can drive the gaseous sulfur sprayed by the nozzle 23 to actively flow towards the mixing plate 34, enabling the gaseous sulfur and methane gas to react in a timely manner when entering the inner furnace body 12, thereby increasing the production of carbon disulfide.

[0063] Referring to Figure 2 , in order to improve the heating effect of the support pipe 13 on the inner furnace body 12, the inside of the guide vane 45 is hollow, and the inside of the guide vane 45 is connected to the inside of the support pipe 13.

The two first discharge pipes 51 are respectively located on both sides of the mixing plate 34 and are both located on the side of the guide vane 45 away from the mixing plate 34. The second discharge pipe 52 is located inside the support pipe 13 and is connected between the two first discharge pipes 51.

[0067] The mixed gas after the reaction in the inner furnace body 12 still contains gaseous sulfur and methane gas. The mixed gas can flow into the two first discharge pipes 51, and then flow from the first discharge pipes 51 into the second discharge pipe 52, the third discharge pipe 53, and the fourth discharge pipe 54. Since the second discharge pipe 52, the third discharge pipe 53, and the fourth discharge pipe 54 are all wrapped by the methane combustion flue gas, the mixed gas will continue to be heated and react when flowing in the second discharge pipe 52, the third discharge pipe 53, and the fourth discharge pipe 54, thereby increasing the production of carbon disulfide.

[0068] Referring to Figure 2 and Figure 4, the carbon disulfide generated by the reaction is mixed in the gaseous sulfur and methane gas, which will affect the reaction efficiency of the gaseous sulfur and methane gas. Therefore, in order to enable the mixed gas to be discharged in time, two first discharge pipes 51 are both connected with exhaust components 6. The exhaust component 6 includes an exhaust telescopic rod 61, a first one-way air valve 62, a second one-way air valve 63, an exhaust cylinder 64 and an exhaust spring 65.

[0069] There are two exhaust telescopic rods 61. The fixed ends of the two exhaust telescopic rods 61 are respectively fixedly penetrated through two parts of the first discharge pipe 51 located outside the support pipe 13. The rodless cavity of the exhaust telescopic rod 61 is in a sealed state, and the rod cavity of the exhaust telescopic rod 61 is communicated with the inner furnace body 12.

[0070] There are two first one-way air valves 62 and two second one-way air valves 63, and they are all in one-to-one correspondence with the exhaust telescopic rod 61. The first one-way air valve 62 and the second one-way air valve 63 are both arranged on the rodless cavity of the exhaust telescopic rod 61. The first one-way air valve 62 is located on the side of the exhaust telescopic rod 61 away from the support pipe 13. The conduction direction of the first one-way air valve 62 is from the outside of the rodless cavity of the exhaust telescopic rod 61 into the inside of the rodless cavity of the exhaust telescopic rod 61. The first one-way air valve 62 is used to make the mixed gas in the inner furnace body 12 flow into the rodless cavity of the exhaust telescopic rod 61.

[0071] The second one-way air valve 63 is located on the side of the exhaust telescopic rod 61 close to the support pipe 13. The conduction direction of the second one-way air valve 63 is from the inside of the rodless cavity of the exhaust telescopic rod 61 into the outside of the rodless cavity of the exhaust telescopic rod 61. The second one-way air valve 63 is used to make the mixed gas in the rodless cavity of the exhaust telescopic rod 61 flow into the part of the first discharge pipe 51 located inside the support pipe 13.

[0072] The exhaust cylinder 64 is fixedly penetrated through the inner furnace body 12 and sleeved on the support pipe 13. The side wall of the exhaust cylinder 64 is wavy in the circumferential direction. There are two exhaust springs 65, and they are in one-to-one correspondence with the exhaust telescopic rod 61. The exhaust spring 65 is arranged in the rod cavity of the exhaust telescopic rod 61. One end of the exhaust spring 65 is fixedly connected to the fixed end of the exhaust telescopic rod 61, and the other end is fixedly connected to the movable end of the exhaust telescopic rod 61. The exhaust spring 65 is used to drive the movable end of the exhaust telescopic rod 61 to abut against the wavy end of the exhaust cylinder 64.

[0073] When the movable end of the exhaust telescopic rod 61 abuts against the trough position of the exhaust cylinder 64, the exhaust telescopic rod 61 draws air through the first one-way air valve 62. When the movable end of the exhaust telescopic rod 61 abuts against the peak position of the exhaust cylinder 64, the exhaust telescopic rod 61 discharges air through the second one-way air valve 63.

[0074] When the support tube 13 rotates, the first discharge pipe 51 rotates along with the support tube 13, and the first discharge pipe 51 drives the extraction telescopic rod 61 to rotate. Under the elastic force of the gas extraction spring 65, the movable end of the extraction telescopic rod 61 can always fit on the end of the extraction tube 64, and the wavy end of the extraction tube 64 can make the extraction telescopic rod 61 cyclically extend and retract. When the extraction telescopic rod 61 is extended, the first one-way gas valve 62 is turned on and the second one-way gas valve 63 is closed, so that the mixed gas is drawn into the rodless cavity of the extraction telescopic rod 61. When the extraction telescopic rod 61 contracts, the first one-way gas valve 62 is closed and the second one-way gas valve 63 is turned on, so that the mixed gas is discharged into the position of the first discharge pipe 51 located in the support tube 13, so that the mixed gas can be actively and timely discharged from the inner furnace box 12, so that the carbon disulfide generated by the reaction is not easily mixed in the gaseous sulfur and methane gas.

[0075] Reference Figure 2 and Figure 5 In order to prolong the reaction time of the mixed gas in the second discharge pipe 52 and the third discharge pipe 53 , an opening and closing component 7 is connected to the fourth discharge pipe 54 .

[0076] Reference Figure 5 The opening and closing assembly 7 includes a closing plate 71, which is arranged at one end of the fourth discharge pipe 54 close to the third discharge pipe 53. The closing plate 71 is fixedly connected with a rotating shaft 72, and the rotating shaft 72 is rotatably penetrated through the fourth discharge pipe 54 and the second smoke pipe 131. The rotating shaft 72 enables the closing plate 71 to rotate relative to the fourth discharge pipe 54, so that the closing plate 71 can close the fourth discharge pipe 54 or open the fourth discharge pipe 54.

[0077] Reference Figure 2 and Figure 5 The end of the rotating shaft 72 away from the closing plate 71 is fixedly connected to an opening and closing gear 73, the opening and closing gear 73 is meshed with an opening and closing rack 74, the opening and closing rack 74 is fixedly connected to a slide bar 75, the slide bar 75 is slidably penetrated on the outer furnace box body 11, and a closing spring 76 is fixed between the slide bar 75 and the outer furnace box body 11. The closing spring 76 is used to drive the slide bar 75 to abut against the wavy end of the exhaust tube 64 near the fourth exhaust pipe 54.

[0078] When the slide bar 75 abuts against the trough position of the exhaust tube 64 , the closing plate 71 closes the fourth exhaust pipe 54 . When the slide bar 75 abuts against the peak position of the exhaust tube 64 , the closing plate 71 opens the fourth exhaust pipe 54 .

[0079] When the exhaust pipe 64 rotates with the inner furnace body 12, the wavy end of the exhaust pipe 64 can drive the sliding rod 75 to slide downward, and the elastic force of the closing spring 76 can drive the sliding rod 75 to slide upward, so that the sliding rod 75 can slide up and down cyclically; when the sliding rod 75 slides downward, the sliding rod 75 will gradually abut against the trough position of the exhaust pipe 64, the sliding rod 75 drives the opening and closing rack 74 to move, the opening and closing rack 74 drives the opening and closing gear 73 to rotate, the opening and closing gear 73 drives the rotating shaft 72 to rotate, and the rotating shaft 72 drives the closing plate 71 to rotate, so that the closing plate 71 closes the fourth discharge pipe 54, enabling the mixed gas to remain in the second discharge pipe 52 and the third discharge pipe 53; when the sliding rod 75 slides upward, the sliding rod 75 will gradually abut against the peak position of the exhaust pipe 64, and the sliding rod 75 drives the closing plate 71 to rotate in the reverse direction through the opening and closing rack 74, the opening and closing gear 73 and the rotating shaft 72, so that the closing plate 71 opens the fourth discharge pipe 54, enabling the mixed gas to be discharged. Thus, the fourth discharge pipe 54 is cyclically closed and opened by the closing plate 71, so that the mixed gas in the second discharge pipe 52 and the third discharge pipe 53 can be intermittently discharged, extending the reaction time of the mixed gas in the second discharge pipe 52 and the third discharge pipe 53, and making the reaction between the gaseous sulfur and methane gas in the mixed gas more complete.

[0080] The implementation principle of a heating furnace for carbon disulfide production in an embodiment of the present application is as follows: during use, liquid sulfur is vaporized into gaseous sulfur in the combustion chamber 21. Under the action of the rotating blades 41, the gaseous sulfur is uniformly introduced into the inner furnace body 12. At the same time, the gaseous sulfur supplies heat to the inner furnace body 12. The methane combustion flue gas in the combustion chamber 21 drives the support pipe 13 to rotate through the driving fan blades 42 and supplies heat to the inner furnace body 12. When the mixing plate 34 rotates with the support pipe 13, methane gas can be uniformly introduced into the inner furnace body 12, and the mixing plate 34 can stir and turn the gaseous sulfur and methane gas, enabling the gaseous sulfur and methane gas to be fully mixed, thereby improving the mixing degree of sulfur and methane and facilitating the efficient production of carbon disulfide.

[0081] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
