DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-5 This application is described in further detail.

[0020] The present application embodiment discloses a heating furnace for producing carbon disulfide. Figure 1 and Figure 2 A heating furnace for producing carbon disulfide includes a furnace body 1, a sulfur supply component 2, a methane supply component 3, a mixing component 4 and an exhaust component 5.

[0021] 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 tube 13. The inner furnace box body 12 is located in the outer furnace box body 11. The support tube 13 is penetrated through the outer furnace box body 11 and the inner furnace box body 12. The support tube 13 is rotatably connected to the outer furnace box body 11 and the inner furnace box body 12 respectively.

[0022] Among them, four rotating grooves are opened on the outer wall of the support tube 13, and the top and bottom ends of the outer furnace box 11 are respectively clamped in two of the rotating grooves, thereby forming a rotating connection structure between the support tube 13 and the outer furnace box 11; the top and bottom ends of the inner furnace box 12 are respectively clamped in the other two rotating grooves, thereby forming a rotating connection structure between the support tube 13 and the inner furnace box 12.

[0023] Specifically, refer to Figure 2 The sulfur supply component 2 can supply gaseous sulfur into the inner furnace box 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 box 11 and is used to burn methane gas. The combustion chamber 21 is connected to a first flue pipe 211. The first flue pipe 211 is connected to one end of the support pipe 13. The first flue pipe 211 is rotatably connected to the support pipe 13 at the connection point. The support pipe 13 can rotate relative to the first flue pipe 211. The first flue pipe 211 is used to allow methane combustion flue gas to pass into the support pipe 13 to provide heat to the inside of the inner furnace box 12. Using the waste heat of the methane combustion flue gas as a heat source can reduce the energy consumption of the heating furnace.

[0024] The liquid sulfur pipe 22 is fixedly installed on the combustion chamber 21 and connected to the side wall of the outer furnace box 11. The liquid sulfur pipe 22 is used to pass liquid sulfur. The liquid sulfur vaporizes into gaseous sulfur when passing through the combustion chamber 21. The gaseous sulfur flows between the outer furnace box 11 and the inner furnace box 12 to provide heat to the inner furnace box 12. The waste heat of the gaseous sulfur is used as a heat source to reduce the energy consumption of the heating furnace. There are two groups of nozzles 23, and the number of nozzles 23 in each group is multiple. The two groups of nozzles 23 are connected to the top and bottom of the inner furnace box 12 respectively. The nozzles 23 are used to spray the gaseous sulfur into the inner furnace box 12, and the gaseous sulfur is easier to diffuse, thereby easily improving the mixing degree.

[0025] Specifically, refer to Figure 2 and Figure 3 The methane supply component 3 is used to supply methane gas to the rotatable inner furnace box 12. The methane supply component 3 includes a methane gas pipe 31, a transfer piece 32, a connecting pipe 33 and a mixing plate 34. The methane gas pipe 31 is fixedly penetrated on the outer furnace box 11 and connected to the transfer piece 32. The methane gas pipe 31 is used to introduce methane gas. The transfer piece 32 is arranged on the inner furnace box 12. There are three connecting pipes 33 and three mixing plates 34, and they correspond to each other. One end of the connecting pipe 33 is connected to the transfer piece 32, and the other end is connected to the hollow mixing plate 34 inside. The mixing plate 34 is connected to the support pipe 13. A plurality of spray holes 341 are opened on the mixing plate 34. The spray holes 341 are used to spray methane gas into the inner furnace box 12. The support tube 13 can drive the mixing plate 34 to rotate with it, so that the mixing plate 34 can not only play the role of injecting methane gas, but also play the role of stirring and mixing the methane gas and gaseous sulfur.

[0026] Among them, the transfer piece 32 is used to keep the methane gas pipe 31 still when the inner furnace box 12 rotates. The transfer piece 32 is used to make the connecting pipe 33 and the mixing plate 34 rotate with the support pipe 13, and the methane gas in the methane gas pipe 31 is passed into the connecting pipe 33 through the transfer piece 32.

[0027] Reference Figure 2 The mixing assembly 4 is connected to the inner furnace box 12 and the support tube 13. The mixing assembly 4 is used to drive the inner furnace box 12 to rotate with the help of the impulse formed by the vaporization of liquid sulfur. The mixing assembly 4 is used to drive the support tube 13 to rotate with the help of the impulse of the methane combustion flue gas. The rotation direction of the support tube 13 is opposite to the rotation direction of the inner furnace box 12. The rotation of the inner furnace box 12 can make the gaseous sulfur pass into the inner furnace box 12 more evenly. The rotation of the support tube 13 can make the methane gas pass into the inner furnace box 12 more evenly. At the same time, the support tube 13 drives the mixing plate 34 to mix and stir the methane gas and gaseous sulfur.

[0028] The exhaust assembly 5 is arranged on the support pipe 13, and is used to allow the mixed gas after the reaction in the inner furnace box 12 to be continuously heated by the methane combustion flue gas in the support pipe 13 during the exhaust process, so that the mixed gas continues to react.

[0029] When in use, liquid sulfur is introduced into the liquid sulfur pipe 22. When the liquid sulfur flows into the combustion chamber 21, it is heated and vaporized. The gaseous sulfur flows into between the outer furnace box 11 and the inner furnace box 12, and then is sprayed into the inner furnace box 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 box 12, and on the other hand, it is conducive to mixing in the inner furnace box 12; the mixing component 4 drives the inner furnace box 12 to rotate with the help of the impulse of the liquid sulfur vaporization, so that the gaseous sulfur can be evenly introduced into the inner furnace box 12 during the rotation of the inner furnace box 12; the methane combustion flue gas in the combustion chamber 21 is introduced into the support tube 13 from the first flue gas pipe 211, and the methane combustion flue gas provides heat to the inner furnace box 12 through the support tube 13, and the waste heat of the gaseous sulfur and the methane combustion flue gas is used to reduce the heat of the gaseous sulfur and the methane combustion flue gas. The energy consumption of the heating furnace is reduced; the mixing component 4 drives the support tube 13 to rotate with the help of the momentum of the methane combustion flue gas, so that the support tube 13 can drive the mixing plate 34 to stir the gaseous sulfur and methane gas, and also enables the methane gas to be uniformly introduced into the inner furnace box 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 methane gas continue to heat and react with the help of the waste heat of the methane combustion flue gas, thereby increasing the yield of carbon disulfide; thus, by uniformly introducing the gaseous sulfur and methane gas and stirring the gaseous sulfur and methane gas through the mixing plate 34, the mixing degree of sulfur and methane can be improved, and the exhaust component 5 continues to react the mixed gas, so that the yield of carbon disulfide can be increased, which is conducive to the efficient production of carbon disulfide.

[0030] Specifically, refer to Figure 2 The mixing assembly 4 includes a rotating blade 41, and a plurality of rotating blades 41 are provided and are fixedly connected to the outer wall of the inner furnace box 12. The plurality of rotating blades 41 are arranged around the rotation axis of the inner furnace box 12. The connection point between the liquid sulfur pipe 22 and the outer furnace box 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 box 12 to rotate.

[0031] When the vaporized gaseous sulfur is introduced into the outer furnace box 11 and the inner furnace box 12, the gaseous sulfur can impact on the rotating blades 41, so that the rotating blades 41 drive the inner furnace box 12 to rotate, so that the rotation of the inner furnace box 12 can be achieved with the help of the impact of the gaseous sulfur.

[0032] Further, refer to Figure 2 The mixing assembly 4 also includes a driving blade 42, and a plurality of driving blades 42 are provided and are all fixedly connected to one end of the support tube 13 close to the first flue gas pipe 211. The plurality of driving blades 42 are arranged around the rotation axis of the support tube 13. When the methane combustion flue gas in the first flue gas pipe 211 impacts the driving blades 42, the driving blades 42 drive the support tube 13 to rotate.

[0033] When the methane combustion flue gas enters the support tube 13, the methane combustion flue gas can impact the driving blades 42, and the driving blades 42 can drive the support tube 13 to rotate, so that the rotation of the support tube 13 can be achieved by the impact of the methane combustion flue gas.

[0034] Reference Figure 2 In order to realize the function of the transfer member 32 , the inner furnace box body 12 includes an upper box body 121 and a lower box body 122 , and a distance is left between the upper box body 121 and the lower box body 122 .

[0035] Specifically, refer to Figure 3 The transfer member 32 includes a connecting ring plate 321, a connecting cylinder 322 and a rotating cylinder 323. Two connecting ring plates 321 are arranged opposite each other. 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. There are multiple connecting rods 3211, and the connecting rods 3211 are used to make the upper box body 121 and the lower box body 122 rotate synchronously.

[0036] The connecting cylinder 322 is sleeved on the two connecting ring plates 321 and is rotatably connected to the two connecting ring plates 321. The methane gas pipe 31 is connected to the connecting cylinder 322. The two connecting ring plates 321 are sleeved on the rotating cylinder 323. The rotating cylinder 323 is rotatably connected to 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 together form an annular closed space. The methane gas in the methane gas pipe 31 can flow into the connecting pipe 33 through the annular closed space.

[0037] Under the action of the connecting tube 322, the methane gas pipe 31 can remain stationary when the inner furnace box 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 tube 33 and the mixing plate 34 can rotate along with the support tube 13, so that the mixing plate 34 can stir the gaseous sulfur and methane gas. With the cooperation of the connecting tube 322 and the rotating cylinder 323, the methane gas can be introduced into the inner furnace box 12 when the inner furnace box 12 rotates.

[0038] Reference 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, and the mixing plate 34 is rotatably connected to the support pipe 13. The mixing assembly 4 also includes a bevel gear ring 43 and a bevel gear 44. The bevel gear ring 43 is fixedly connected to the inner furnace box 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.

[0039] When the support tube 13 drives the connecting tube 33 and the mixing plate 34 to rotate, the bevel gear 44 connected to the connecting tube 33 can rotate under the drive of the bevel gear ring 43, the bevel gear 44 drives the connecting tube 33 to rotate, and the connecting tube 33 can drive the mixing plate 34 to flip, so that the mixing plate 34 can flip the gaseous sulfur and methane gas while stirring the gaseous sulfur and methane gas, thereby improving the mixing effect of the mixing plate 34.

[0040] Reference Figure 2 In order to drive the gaseous sulfur to actively flow toward the methane gas, the mixing assembly 4 also includes guide blades 45. Two groups of guide blades 45 are provided and are both located in the inner furnace box 12. The two groups of guide blades 45 are both fixedly connected to the support tube 13 and are respectively located on both sides of the mixing plate 34. The number of each group of guide blades 45 is three. Each group of guide blades 45 is arranged around the rotation axis of the support tube 13. The two groups of guide blades 45 are used to make the gaseous sulfur flow toward the mixing plate 34 when the support tube 13 rotates.

[0041] When the support tube 13 drives the mixing plate 34 to rotate, the support tube 13 can synchronously drive the two groups of guide blades 45 to rotate. The airflow formed by the rotation of the two groups of guide blades 45 can drive the gaseous sulfur sprayed by the nozzle 23 to actively flow toward the mixing plate 34, so that the gaseous sulfur and methane gas can react in time when entering the inner furnace box 12, thereby increasing the output of carbon disulfide.

[0042] Reference Figure 2 In order to improve the heating effect of the support tube 13 on the inner furnace box 12, the guide blade 45 is hollow inside, and the inside of the guide blade 45 is connected to the inside of the support tube 13. The methane combustion flue gas in the support tube 13 can flow into the inside of the guide blade 45, thereby increasing the heating area of ​​the methane combustion flue gas.

[0043] Specifically, refer to Figure 2 The exhaust assembly 5 includes a first exhaust pipe 51 , a second exhaust pipe 52 , a third exhaust pipe 53 and a fourth exhaust pipe 54 .

The second flue gas pipe 131 is rotatably connected to the support pipe 13 at the connection point. The second flue gas pipe 131 is fixedly connected to the outer furnace box 11 .

[0045] The first exhaust pipe 51 is in the shape of a rectangular tube. Two first exhaust pipes 51 are provided and both are fixedly penetrated on the support pipe 13. The two first exhaust pipes 51 are respectively located on both sides of the mixing plate 34 and are both located on the side of the guide blade 45 away from the mixing plate 34. The second exhaust pipe 52 is located in the support pipe 13 and is connected between the two first exhaust pipes 51. The third exhaust pipe 53 is located in the support pipe 13 and is connected to the first exhaust pipe 51 near the second smoke pipe 131.

The fourth exhaust pipe 54 is connected to the third exhaust pipe 53, and the fourth exhaust pipe 54 is rotatably connected to the third exhaust pipe 53 at the connection point.

[0046] The mixed gas after the reaction in the inner furnace box 12 still contains gaseous sulfur and methane gas. The mixed gas can flow into the two first exhaust pipes 51, and then flow from the first exhaust pipe 51 into the second exhaust pipe 52, the third exhaust pipe 53 and the fourth exhaust pipe 54. Since the second exhaust pipe 52, the third exhaust pipe 53 and the fourth exhaust pipe 54 are all wrapped in methane combustion flue gas, the mixed gas will continue to be heated and reacted when flowing in the second exhaust pipe 52, the third exhaust pipe 53 and the fourth exhaust pipe 54, thereby increasing the production of carbon disulfide.

[0047] Reference Figure 2 and Figure 4The 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, the two first discharge pipes 51 are connected to the exhaust assembly 6, and the exhaust assembly 6 includes an exhaust telescopic rod 61, a first one-way air valve 62, a second one-way air valve 63, an exhaust tube 64 and an exhaust spring 65.

[0048] Two exhaust telescopic rods 61 are provided, and the fixed ends of the two exhaust telescopic rods 61 are respectively fixedly penetrated at two positions of the first exhaust pipe 51 outside the support tube 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 connected to the inner furnace box 12.

[0049] There are two first one-way air valves 62 and second one-way air valves 63, and both correspond to the extraction telescopic rod 61 one by one. The first one-way air valve 62 and the second one-way air valve 63 are both arranged on the rodless cavity of the extraction telescopic rod 61. The first one-way air valve 62 is located on the side of the extraction telescopic rod 61 away from the support tube 13. The conduction direction of the first one-way air valve 62 is from the outside of the rodless cavity of the extraction telescopic rod 61 to the inside of the rodless cavity of the extraction telescopic rod 61. The first one-way air valve 62 is used to allow the mixed gas in the inner furnace box 12 to flow into the rodless cavity of the extraction telescopic rod 61.

[0050] The second one-way air valve 63 is located on the side of the extraction telescopic rod 61 close to the support tube 13. The conduction direction of the second one-way air valve 63 is from the inside of the rodless cavity of the extraction telescopic rod 61 to the outside of the rodless cavity of the extraction telescopic rod 61. The second one-way air valve 63 is used to allow the mixed gas in the rodless cavity of the extraction telescopic rod 61 to flow into the position of the first exhaust pipe 51 located in the support tube 13.

[0051] The exhaust tube 64 is fixedly installed on the inner furnace box 12 and sleeved on the support tube 13. The side wall of the exhaust tube 64 is wavy in the circumferential direction. Two exhaust springs 65 are provided, and they correspond to the exhaust telescopic rod 61 one by one. The exhaust springs 65 are 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 tube 64.

[0052] When the movable end of the exhaust telescopic rod 61 abuts against the trough position of the exhaust tube 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 tube 64, the exhaust telescopic rod 61 exhausts air through the second one-way air valve 63.

[0053] 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.

[0054] 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 .

[0055] 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.

[0056] 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.

[0057] 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 .

[0058] When the exhaust tube 64 rotates with the inner furnace box 12, the wavy end of the exhaust tube 64 can drive the slide bar 75 to slide down, and the elastic force of the closing spring 76 can drive the slide bar 75 to slide up, so that the slide bar 75 can slide up and down cyclically; when the slide bar 75 slides down, it will gradually abut against the trough position of the exhaust tube 64, and the slide bar 75 drives the opening and closing rack 74 to move, and the opening and closing rack 74 drives the opening and closing gear 73 to rotate, and 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, so that the mixed gas can remain in the second discharge pipe 52 and the third discharge pipe 53; when the slide bar 75 slides up, the slide bar 75 will gradually abut against the wave crest position of the exhaust tube 64, and the slide bar 75 drives the closing plate 71 to rotate in the opposite 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 exhaust pipe 54, so that the mixed gas can be discharged, thereby cyclically closing and opening the fourth exhaust pipe 54 by the closing plate 71, so that the mixed gas in the second exhaust pipe 52 and the third exhaust pipe 53 can be discharged intermittently, thereby extending the reaction time of the mixed gas in the second exhaust pipe 52 and the third exhaust pipe 53, so that the reaction of the gaseous sulfur and methane gas in the mixed gas is more thorough.

[0059] The implementation principle of a heating furnace for carbon disulfide production in an embodiment of the present application is as follows: when in use, liquid sulfur is vaporized into gaseous sulfur through the combustion chamber 21, and under the action of the rotating blades 41, the gaseous sulfur is evenly introduced into the inner furnace box 12, and at the same time, the gaseous sulfur supplies heat to the inner furnace box 12, and the methane combustion flue gas in the combustion chamber 21 drives the support tube 13 to rotate through the driving blades 42, and supplies heat to the inner furnace box 12, and the methane gas can be evenly introduced into the inner furnace box 12 when the mixing plate 34 rotates with the support tube 13, and the mixing plate 34 can stir and turn over the gaseous sulfur and methane gas, so that the gaseous sulfur and methane gas can be fully mixed, thereby improving the mixing degree of sulfur and methane, which is conducive to the efficient production of carbon disulfide.
