[0024] Please refer to Figure 1 , and now a sulfur-burning furnace provided by the present utility model will be described. A sulfur-burning furnace includes a furnace body 1 and a flow guiding mechanism.

[0025] The furnace body 1 is horizontally arranged. An air inlet end 2 and an exhaust end 3 are respectively arranged at both ends of the furnace body 1. A conical cloth disk 4 is arranged at the air inlet end 2 of the furnace body 1. An outer end of the conical cloth disk 4 is connected to a feed pipe 5. An inner end of the conical cloth disk 4 is located in the inner cavity of the furnace body 1. The cross-section of the inner cavity of the conical cloth disk 4 increases sequentially from the outside to the inside. A plurality of nozzles 6 are circumferentially and evenly arranged at the inner end of the conical cloth disk 4. The flow guiding mechanism includes a plurality of flow guiding components arranged alternately and at intervals along the axis of the furnace body 1. The flow guiding components include a plurality of baffle plates 7 arranged sequentially along the inner peripheral wall of the furnace body 1. A guiding gap 8 is formed between two adjacent baffle plates 7 in the same flow guiding component. The guiding gap 8 forms a guiding air flow for guiding the transmission of sulfur components. The directions of the guiding air flows of two adjacent flow guiding components are opposite or arranged at an angle.

[0026] A sulfur-burning furnace provided by the utility model, compared with the prior art, after the inner cavity of the furnace body 1 is heated to a predetermined temperature, sulfur powder enters the conical cloth disk 4 through the feed pipe 5 and is then sprayed into the inner cavity of the furnace body 1 through a plurality of nozzles 6. At the same time, compressed gas is blown into the furnace body 1 through the air inlet end 2 of the furnace body 1. The compressed gas drives the sulfur powder to sequentially pass through a plurality of flow guiding components. When passing through the flow guiding components, the sulfur powder forms a guiding air flow under the guidance of adjacent baffle plates 7. The guiding air flow directions of adjacent flow guiding components are opposite or form an included angle device, so that the sulfur powder forms a continuously reversing transmission path in the inner cavity of the furnace body 1, and the overall transmission path of the sulfur powder in the inner cavity of the furnace body 1 is extended. A sulfur-burning furnace provided by the utility model can extend the overall transmission path of the sulfur powder in the inner cavity of the furnace body 1, increase the reaction time of the sulfur powder in the inner cavity of the furnace body 1, improve the burning effect of the sulfur powder, reduce residues, and ensure the preparation efficiency of sulfur dioxide.

[0027] Please refer to Figure 1 , the baffle plates 7 in adjacent two flow guiding components are symmetric up and down, which can change the direction of the guiding gap 8 formed by the baffle plates 7 in adjacent flow guiding components. At the same time, the same kind of baffle plate 7 can also be used to complete the installation of all flow guiding components.

[0028] Please refer to Figure 2 , both sides of the baffle plate 7 are provided with an arc-shaped working surface 9 and an arc-shaped non-working surface 10. Both ends of the baffle plate 7 are respectively provided with an arc-shaped end 11 and a conical end 12. The radian of the arc-shaped working surface 9 is smaller than the radian of the arc-shaped non-working surface 10. The arc-shaped working surfaces 9 and arc-shaped non-working surfaces 10 of two adjacent baffle plates 7 in the same flow guiding component form a guiding gap 8. Since the radian of the arc-shaped working surface 9 is different from the radian of the arc-shaped non-working surface 10, the directions of the guiding gaps formed by two baffle plates 7 in adjacent flow guiding components will be different, so as to achieve the purpose of forming guiding air flows in different directions when the sulfur powder passes through adjacent wire components.

[0029] Please refer to Figure 1 , the exhaust direction of the exhaust end 3 of the furnace body 1 is the same as the axial direction of the furnace body 1, which is more conducive to the discharge of sulfur dioxide gas. A filter layer is provided at the exhaust end 3 of the furnace body 1, which can prevent the uncompletely treated sulfur powder from being discharged together with the sulfur dioxide gas, and can also block impurity particles.

[0030] Please refer to Figure 1, the intake direction of the intake end 2 of the furnace body 1 is perpendicular to the axial direction of the furnace body 1. A baffle 13 is arranged on one side of the inner cavity of the furnace body 1 close to the intake end 2. An intake gap 14 is formed between the baffle 13 and the intake end 2 of the furnace body 1. A vent hole 15 corresponding to the conical cloth disc 4 is opened in the middle of the baffle 13, and the vent hole 15 communicates with the intake gap 14. Compressed gas enters the intake gap 14 through the intake end 2, and then is blown into the inner cavity of the furnace body 1 through the vent hole 15. At the same time, compressed air enters the inner cavity of the furnace body 1 together with the sulfur powder ejected by a plurality of nozzles 6, which can improve the spraying efficiency of the sulfur powder, increase the initial velocity of the sulfur powder, and better complete the transmission in the inner cavity of the furnace body 1.

[0031] Please refer to Figure 3 , the nozzle 6 includes a nozzle tube 16 and a distribution head. A spray hole is opened at the end of the nozzle tube 16. The distribution head penetrates through the spray hole and is connected to the inner wall of the nozzle tube 16. An injection gap 17 is formed between the distribution head and the spray hole. The part of the distribution head located outside the spray hole forms a conical distribution head 18, and the outer diameter of the conical distribution head 18 increases from inside to outside. The part of the distribution head located inside the spray hole forms a conical guide head 19, and the outer diameter of the conical guide head 19 increases from inside to outside. The sulfur powder is sprayed into the inner cavity of the furnace body 1 through the spray hole of the nozzle tube 16. The sulfur powder first forms a first diffusion to the periphery under the guidance of the conical guide head 19, and then is ejected from the injection gap 17. After that, it forms a second diffusion to the periphery under the guidance of the conical distribution head 18. Finally, the sulfur powder ejected by the nozzle 6 enters the inner cavity of the furnace body 1 in a dispersed state, which can make the sulfur powder react more fully.

[0032] Among them, the width of the injection gap 17 decreases sequentially from inside to outside. Specifically, the inner diameter of the spray hole decreases from inside to outside. The position of the distribution head corresponding to the spray hole is a straight section. The sulfur powder passing through the conical guide head 19 will impact the inclined inner peripheral wall of the spray hole and rebound, and then diffuse to the periphery through the conical distribution head 18. The inner peripheral wall of the sulfur powder device spray hole can further disperse the sulfur powder and improve the reaction efficiency of the sulfur powder in the inner cavity of the furnace body 1.

[0033] In addition, a foundation 20 is arranged below the furnace body 1. A guide rail 21 arranged along the axis of the furnace body 1 is arranged on the foundation 20. A plurality of pulleys 22 are arranged along the axial direction below the furnace body 1. The plurality of pulleys 22 are slidably arranged on the guide rail 21. One end of the furnace body 1 is fixed to the guide rail 21 or the foundation 20. When the temperature of the furnace body 1 changes, a large deformation will occur in the axial direction of the furnace body 1. A fixing block 23 is arranged at one end of the furnace body 1, and the fixing block 23 is fixed to the guide rail 21 or the foundation 20. When a large deformation occurs in the axial direction of the furnace body 1, one end of the furnace body 1 does not move under the action of the fixing block 23, and the non-fixed part will axially move through the cooperation of the pulley 22 and the slide rail to adapt to the axial change of the furnace body 1 itself, and the stress generated by the heating deformation of the furnace body 1 can be released, effectively protecting the furnace body 1.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
