Abstract
Description
Technical Field
[0001] The invention relates to the technical field of reactors, in particular to an anti-adhesion chemical safety reactor. Background Art
[0002] A reactor is a container for chemical reactions. It can provide a closed and controllable environment for chemical reactions, allowing the raw materials to react under specific conditions of temperature, pressure, stirring, etc., thereby converting the desired products. Therefore, it is widely used in the fields of chemical industry, pharmaceuticals, etc. Reactors can be divided into intermittent reactors, continuous reactors, and semi-continuous reactors according to different operating methods.
[0003] During the production process of medium nickel matte obtained by wet leaching process of low-grade nickel matte, a large amount of waste gas mainly composed of hydrogen sulfide gas will be generated. In order to avoid direct discharge of waste gas containing hydrogen sulfide gas and cause environmental pollution and waste of resources, chemical reactors are needed for high-concentration hydrogen sulfide gas to convert it into elemental sulfur, so as to achieve the treatment of hydrogen sulfide gas and effective utilization of resources. Since the volume of the reactor is limited and the volume of hydrogen sulfide gas to be treated far exceeds the volume of the reactor, it is necessary to select a continuous reactor to treat the hydrogen sulfide gas.
[0004] The process of preparing sulfur by reacting hydrogen sulfide and sulfur dioxide in salt water is as follows: hydrogen sulfide and sulfur dioxide gases in a volume ratio of 2 and 1 respectively enter a reaction zone containing a reaction solution through an air inlet at the top of a reactor; when hydrogen sulfide and sulfur dioxide gases enter the salt water solution in the reaction zone, they are vigorously stirred by a stirring paddle at the bottom of the reactor, the two phases are in close contact, and react fully; after the reaction is completed, the sulfur solution generated is separated by sedimentation to obtain sulfur and a salt water solution.
[0005] In the actual production process, after the hydrogen sulfide gas and the sulfur dioxide gas fully react in the solution, the generated sulfur will adhere to the inner wall of the reactor. After the sulfur particles are scraped off by a scraper ring, the sulfur particles will adhere to the bottom of the scraper ring, resulting in the need to clean the scraper ring regularly. In addition, the continuous reaction causes an increase in sulfate ions in the reaction solution, and then the concentration of the reaction solution decreases, causing the hydrogen sulfide gas and sulfur dioxide gas introduced at a certain rate to be unable to react in the reaction solution and be directly discharged. In order to avoid a large amount of reaction gas being discharged, the prior art often sets a gas sensor in the gas outlet to stop the gas input when the discharge of hydrogen sulfide gas or sulfur dioxide gas is detected, and replace the reaction solution in time. However, hydrogen sulfide and sulfur dioxide are acidic gases, which greatly shortens the life of the gas sensor. When the gas sensor fails, a large amount of hydrogen sulfide gas and sulfur dioxide gas will be discharged, causing a safety accident.
[0006] Therefore, an anti-adhesion chemical safety reactor is proposed. Summary of the invention
[0007] The object of the present invention is to provide an anti-adhesion chemical safety reactor. When the gas cannot react with the solution and escapes, the gas passes through the rotary blade to drive the rotary blade to rotate, and then drives the limiting ring to drive the suction cup to move upward to block the gas outlet. When the limiting ring moves downward to scrape off the sulfur particles adhered to the reactor body, the driving ring keeps rotating to throw off the scraped sulfur particles. This solves the problem that when the gas sensor fails due to corrosion by acidic gas, the hydrogen sulfide gas and sulfur dioxide gas that are not fully reacted are directly discharged, which is easy to cause safety accidents, and the scraping surface of the scraping ring needs to be cleaned regularly after the scraping ring scrapes off the sulfur particles. The safety of the reactor body is greatly improved, and a large amount of unreacted hydrogen sulfide gas and sulfur dioxide gas are prevented from escaping. When the sulfur particles are scraped off, the adhesion of sulfur particles can be avoided, and there is no need to clean the limiting ring and the rotating ring regularly.
[0008] To achieve the above object, the present invention provides the following technical solutions:
[0009] The invention discloses an anti-adhesion chemical safety reactor, comprising a reactor body, a sealing cover, an exhaust pipe, a heater, a discharge pipe, a stirring assembly, a reduction motor, an air inlet pipe, a sulfur removal assembly and a transmission assembly. The stirring assembly is sealed and installed on the top of the sealing cover, and the stirring assembly extends into the reactor body. The reduction motor is installed on the top of the stirring assembly, the air inlet pipe is connected with the stirring assembly, the sulfur removal assembly is installed in the reactor body, and the transmission assembly is installed on the top of the sulfur removal assembly. Gas enters the reactor body through the stirring assembly, and the unreacted gas drives the transmission assembly to rotate. The rotating transmission assembly drives the sulfur removal assembly to move upward in line with the inner wall of the reactor body, and the transmission assembly moves upward together with the sulfur removal assembly to block the exhaust pipe. When no gas is introduced, the sulfur removal assembly moves downward in line with the inner wall of the reactor body until the sulfur removal assembly contacts the stirring assembly. The stirring assembly drives the sulfur removal assembly to continue to move downward in line with the inner wall of the reactor body, and the sulfur removal assembly scrapes sulfur particles and rotates to throw away the sulfur particles.
[0010] As described above, before the reaction solution is injected into the reactor body, the sulfur removal component is lifted to a position above the liquid level. When the sulfur removal component is driven by the stirring component to move downward to scrape off the sulfur particles adhering to the inner wall of the reactor body, the bottom of the component rotates continuously, and the sulfur particles adhering to the sulfur removal component are separated from the sulfur removal component under the action of centrifugal force, thereby ensuring the cleanliness of the sulfur removal component and avoiding the need to clean the sulfur removal component regularly. At the same time, when the sulfur removal component moves downward, the transmission component is driven, which is conducive to the rapid drying of the sulfur removal component by driving the rotary blade to rotate, and further prevents the wet sulfur particles from adhering to the sulfur removal component.
[0011] In addition, when the concentration of the reaction solution decreases and the hydrogen sulfide gas and sulfur dioxide gas cannot fully react and escape, the gas passes through the transmission assembly and drives the transmission assembly to rotate. At this time, the transmission assembly drives the sulfur removal assembly to move upward and close the exhaust port, thereby preventing the large-scale discharge of hydrogen sulfide gas and sulfur dioxide gas, and conveniently stopping the gas input in time to ensure the safety of the reactor body.
[0012] Preferably, a one-way valve is installed on the air inlet pipe, and a gas sensor is installed in the exhaust pipe. The gas sensor is connected to the one-way valve through a controller and a circuit board.
[0013] As mentioned above, when the gas sensor is in normal use, it will detect the gas discharged from the inside of the reactor body. When the hydrogen sulfide gas and the sulfur dioxide gas fully react, no gas is discharged from the reactor body. Therefore, when the gas sensor detects the gas discharge, it means that the hydrogen sulfide gas or the sulfur dioxide gas is not completely reacted and is directly discharged. At this time, the gas sensor first closes the one-way valve through the controller and the circuit board to stop the introduction of hydrogen sulfide gas and sulfur dioxide gas to avoid large-scale leakage of hydrogen sulfide gas and sulfur dioxide gas to cause safety accidents; however, the gas sensor can only detect when hydrogen sulfide gas and sulfur dioxide gas are discharged, and hydrogen sulfide gas and sulfur dioxide gas are acidic gases. Therefore, the life of the gas sensor in this working environment is limited. When the gas sensor fails, the transmission component blocks the exhaust port to avoid large-scale discharge of hydrogen sulfide gas and sulfur dioxide gas, thereby fully ensuring the safety of the reactor body in the working state.
[0014] Preferably, the stirring assembly includes a sealing cylinder, a transmission shaft, a screw and a stirring plate, the sealing cylinder is installed on the top of the sealing cover, the top of the transmission shaft is rotatably connected to the inner circumference of the sealing cylinder, and the bottom of the transmission shaft passes through the sealing cover and extends to the inside of the reactor body, the screw is installed at the bottom end of the transmission shaft, and the stirring plate is installed at the bottom end of the screw, the transmission shaft, screw and stirring plate are all arranged as hollow structures, and the outer periphery of the transmission shaft located on the inner side of the sealing cylinder and the surface of the stirring plate are constructed with air holes, and the diameter of the screw is greater than the diameter of the transmission shaft.
[0015] As described above, since the gas enters the stirring plate through the hollow structure of the transmission shaft and the screw, when the gas flows out of the stirring plate, the contact time with the reaction solution is extended. Combined with the rotation of the stirring plate, the gas is evenly distributed in the reaction solution, thereby optimizing the reaction process of hydrogen sulfide gas and sulfur dioxide gas with the reaction solution, thereby improving the efficiency of hydrogen sulfide gas treatment to produce sulfur.
[0016] Preferably, the sulfur removal component includes a limiting ring, a rotating ring, a bar frame, a limiting block, a protective cover and a wall-adhering mechanism. The limiting ring is provided with symmetrical limiting grooves on its outer circumference. The limiting ring is slidably fitted with the vertical bars through the limiting grooves. The vertical bars are fitted and installed on the inner circumference of the reactor body. The rotating ring is rotatably fitted on the bottom of the limiting ring. The outer circumference of the limiting ring and the outer circumference of the rotating ring are constructed with inclined surfaces with consistent curvature. The bar frame is installed on the inner circumference of the limiting ring, and a threaded hole adapted to the screw rod is provided at the center of the bar frame. The limiting block is installed on the inner circumference of the limiting ring, and the end of the limiting block is limitedly and slidably fitted with the rotating ring. The protective cover is fitted and installed on the surface of the limiting ring. The wall-adhering mechanism is installed on the surface of the limiting ring, and the wall-adhering mechanism is connected to the rotating ring.
[0017] As mentioned above, when the limiting ring is driven by the stirring assembly to move the rotating ring downward, the sulfur particles adhering to the inner wall of the reactor body are scraped off by the limiting ring and are located at the periphery of the limiting ring and the rotating ring. At this time, the rotating ring will continue to rotate when moving downward, and then the sulfur particles on the rotating ring and the periphery of the rotating ring will be thrown away under the action of centrifugal force. At the same time, under the action of the rotating blades, the drying of the rotating ring and the limiting ring is accelerated, which fully avoids the sulfur particles from adhering to the bottom surface of the rotating ring and the limiting ring.
[0018] Preferably, an annular strip is installed on the top of the rotating ring, and an annular groove adapted to the end of the limit block is opened on the inner circumference of the annular strip.
[0019] As described above, under the action of the annular strip, the annular groove and the limiting block, the stability between the limiting ring and the rotating ring can be fully maintained by increasing the contact area between the limiting ring and the rotating ring.
[0020] Preferably, the wall-adhering mechanism includes a first fixed block, a first bevel gear, a rubber wheel, a second bevel gear, a spur gear, a second fixed block and a separation shaft, the first fixed block and the second fixed block are both installed on the top of the limit ring, the separation shaft is rotatably connected to the first fixed block, the first bevel gear and the rubber wheel are both sleeved on the separation shaft, and the rubber wheel is rollingly fitted with the inner wall of the reactor body, the second bevel gear is coaxially arranged with the spur gear, and the spur gear is rotatably fitted with the second fixed block, the second bevel gear is meshed with the first bevel gear, and the spur gear is meshed with the annular bar.
[0021] As described above, through the fit between the rubber wheel and the inner wall of the reactor body, when the limit ring produces a vertical displacement, the rubber wheel will rotate, and the rubber wheel drives the first bevel gear to rotate, and then the first bevel gear drives the rotating ring to rotate in the corresponding direction through the second bevel gear and the spur gear, so that the sulfur particles in contact with the outer periphery of the rotating ring are separated from the rotating ring and the limit ring under the action of centrifugal force, so as to fully maintain the cleanliness of the rotating ring and effectively prevent the sulfur particles from moving to the surface of the limit ring.
[0022] Preferably, a thread groove is formed on the outer circumference of the separation shaft, the rubber wheel is fitted with the thread groove, a spring is sleeved on the outer circumference of the separation shaft, and the spring abuts between the first fixing block and the rubber wheel.
[0023] As described above, under the action of the thread groove and the spring, when the limit ring reaches the highest point, the limit ring cannot move further upward, and the rubber wheel moves toward the spring side under the action of the thread groove and separates from the first bevel gear, thereby reducing the collision effect when the transmission assembly contacts the reactor body.
[0024] Preferably, the transmission assembly includes a fixed sleeve, a rotary blade, a long shaft, a third bevel gear, a fourth bevel gear and a safety closing mechanism, the fixed sleeve is installed on the side wall of the protective cover, the rotary blade is rotatably installed on the top of the bar frame, the long shaft is rotatably installed on the inner periphery of the fixed sleeve, and the end of the long shaft is connected to the spur gear shaft, the third bevel gear is installed at the end of the long shaft, the fourth bevel gear is installed on the top of the rotary blade, and the fourth bevel gear is meshed with the third bevel gear.
[0025] As mentioned above, when the gas after the reaction rises and passes through the rotor blades, it can drive the rotor blades and the fourth bevel gear to rotate, and the fourth bevel gear drives the long shaft to rotate through the third bevel gear, and then the long shaft drives the spur gear to rotate, thereby providing power input for the sulfur removal component through the transmission component. When the sulfur removal component moves up, it drives the safety closing mechanism to move up synchronously. When the top of the safety closing mechanism fits with the end of the exhaust pipe, the exhaust port of the reactor body is blocked, thereby avoiding the leakage of hydrogen sulfide gas and sulfur dioxide gas, thereby fully improving the safety of the reactor body.
[0026] Preferably, the outer circumference of the top of the rotating ring is flush with the outer circumference of the bottom of the limiting ring, and the diameter value of the inner circumference of the rotating ring is equal to the diameter value of the inner circumference of the limiting ring.
[0027] As mentioned above, the outer circumferential inclined surfaces of the rotating ring and the limiting ring are flush, thereby forming a complete inclined surface on the outer circumference of the rotating ring and the limiting ring.
[0028] Preferably, the safety closing mechanism includes a safety rod, a slide groove, a sliding rod and a suction cup. The safety rod is installed on the top of the fixed sleeve, and the safety rod is located directly below the connection between the exhaust pipe and the reactor body. The slide groove is constructed inside the safety rod, the sliding rod slides through the safety rod, and the suction cup is installed on the top of the sliding rod.
[0029] As mentioned above, after the suction cup moves up to the highest point with the sulfur removal component and closes the exhaust port, since the introduction of hydrogen sulfide gas and sulfur dioxide gas has been stopped at this time, and the reaction solution is gradually discharged, the rotary blade stops rotating after losing the action of hydrogen sulfide gas and sulfur dioxide gas, and the safety rod moves down to the connection between the frame and the screw rod with the limit ring under the action of its own gravity. At this time, the sliding rod maintains an unchanged height, thereby maintaining the sealing effect of the suction cup on the exhaust port, preventing hydrogen sulfide gas and sulfur dioxide gas from being discharged in large quantities from the reactor body; and as the solution is gradually discharged, the pressure in the space above the solution decreases, thereby separating the suction cup from the reactor body, and there is no need to manually separate the suction cup from the reactor body.
[0030] Compared with the prior art, the present invention has the following beneficial effects:
[0031] 1. In the present invention, when the concentration of the reaction solution decreases and the hydrogen sulfide gas and the sulfur dioxide gas cannot fully react and escape, the gas passing through the rotary blade will drive the limit ring and the suction cup to move upward together to close the exhaust port, thereby preventing the hydrogen sulfide gas and the sulfur dioxide gas from being discharged in large quantities, thereby ensuring the safety of the reactor body; in the process where the limit ring of the sulfur removal component is driven by the stirring component to move downward to scrape off the sulfur particles adhering to the inner wall of the reactor body, the rotating ring at the bottom thereof rotates continuously, and the sulfur particles adhering to the bottom surfaces of the rotating ring and the limit ring are scraped off and separated from the bottom surfaces of the rotating ring and the limit ring under the action of centrifugal force, thereby ensuring the cleanliness of the bottom surfaces of the rotating ring and the limit ring, and there is no need to clean them regularly. At the same time, the limit ring reversely drives the rotary blade to rotate, and by driving the rotary blade to rotate, the limit ring and the rotating ring are quickly dried, further preventing the wet sulfur particles from adhering to the sulfur removal component, thereby avoiding the need to clean the sulfur removal component regularly.
[0032] 2. By means of the safety closing mechanism and the rotary vanes, when hydrogen sulfide gas and sulfur dioxide gas escape due to incomplete reaction, the gas escapes through the rotary vanes and drives the rotary vanes to rotate, which can provide power for the safety closing mechanism to move upward, thereby closing the discharge port of the reactor body. In addition, when the sulfur removal component moves downward, the rotary vanes rotate driven by the sulfur removal component, thereby accelerating the air flow rate at the limit ring and the rotating ring, which is beneficial for drying the sulfur particles adhering to the rotating ring and the limit ring, thereby avoiding the sulfur particles adhering to the rotating ring and the limit ring, thereby fully ensuring the cleanliness of the rotating ring and the limit ring.
[0033] 3. Through the safety closing mechanism, when the suction cup contacts the reactor body and closes the exhaust port, the introduction of hydrogen sulfide gas and sulfur dioxide gas is stopped. Then, in the process of gradually discharging the reaction solution, as the solution is gradually discharged, the pressure in the space above the solution decreases, thereby separating the suction cup from the reactor body. There is no need to manually separate the suction cup from the reactor body, and subsequent use is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0044] See also Figures 1 to 8 The present invention provides an anti-adhesion chemical safety reactor, and the technical solution is as follows:
[0045] A chemical safety reactor with anti-adhesion comprises a reactor body 1, a sealing cover 2, an exhaust pipe 6, a heater 7, and a discharge pipe 8. The sealing cover 2 is installed and connected with the reactor body 1 through a sealing member, the exhaust pipe 6 is installed on the top of the reactor body 1, the heater 7 is installed in a close fit on the outer periphery of the reactor body 1, the discharge pipe 8 is installed at the bottom of the reactor body 1, and the precipitate generated by the reaction and the solution after the reaction are discharged through the discharge pipe 8. The reactor also comprises a stirring component 3, a reduction motor 4, an air intake pipe 5, a sulfur removal component 9 and a transmission component 10. The stirring component 3 is sealed and installed on the top of the sealing cover 2. The connection position between the stirring component 3 and the sealing cover 2 is sealed, and the stirring component 3 extends to the inside of the reactor body 1. The reduction motor 4 is installed on the top of the stirring component 3. The reduction motor 4 provides power input for the stirring component 3. The air intake pipe 5 is connected with the stirring component 3. The gas introduced into the air intake pipe 5 enters the reactor body 1 through the stirring component 3 and then flows out from the deep of the reaction solution, which effectively prolongs the contact time between the gas and the reaction solution, is beneficial to improving the production efficiency of sulfur, and improves the sulfur removal efficiency. The sulfur removal component 9 is installed inside the reactor body 1, and the transmission component 10 is installed on the top of the sulfur removal component 9. The gas enters the reactor body 1 through the stirring component 3. The unreacted gas drives the transmission component 10 to rotate. The rotating transmission component 10 drives the sulfur removal component 9 to move up against the inner wall of the reactor body 1. At the same time, the transmission component 10 moves up with the sulfur removal component 9 to block the exhaust pipe 6. When no gas is introduced, the sulfur removal component 9 moves down against the inner wall of the reactor body 1 until the sulfur removal component 9 contacts the stirring component 3. The stirring component 3 drives the sulfur removal component 9 to continue to move down against the inner wall of the reactor body 1. Before injecting the reaction solution into the reactor body 1, the stirring component 3 is started in advance to move the sulfur removal component 9 to a position above the liquid level. At this time, the sulfur removal component 9 is separated from the stirring component 3 and maintained at a constant height. The sulfur removal component 9 scrapes off the sulfur particles and rotates to throw off the sulfur particles at the same time, thereby ensuring the cleanliness of the sulfur removal component 9 when removing the sulfur particles, avoiding the need to regularly clean or replace the sulfur removal component 9.

The gas sensor 61 is connected to the one-way valve 51 through a controller and a circuit board. When the gas sensor 61 is used normally, it will detect the gas discharged from the inside of the reactor body 1. When the hydrogen sulfide gas and the sulfur dioxide gas fully react, no gas is discharged from the reactor body 1. At this time, no gas escapes from the exhaust pipe 6. When the gas sensor 61 detects that the gas is discharged, it means that the hydrogen sulfide gas or the sulfur dioxide gas is not completely reacted and is directly discharged. At this time, the gas sensor 61 first closes the one-way valve 51 through the controller and the circuit board to stop the introduction of hydrogen sulfide gas and sulfur dioxide gas.

Combined with the rotation of the stirring plate 34, the gas is evenly distributed in the reaction solution, thereby improving the efficiency of hydrogen sulfide gas treatment to produce sulfur; considering that sulfur production requires the introduction of hydrogen sulfide gas and sulfur dioxide gas at the same time, in order to avoid the two gases being introduced through a single pipeline and reacting inside the transmission shaft 32 and the screw rod 33, another air inlet pipe 5 is connected to the bottom of the screw rod 33, and an isolation plate is provided in the cavity of the stirring plate 34, and the two gases flow out from the upper surface and bottom surface of the stirring plate 34 respectively, thereby preventing the sulfur element produced by the direct reaction of the gases from causing pore blockage.

Therefore, when used in the reactor body 1, it can not only resist the corrosion of sulfuric acid, but also maintain a close fit with the inner wall of the reactor body 1.

[0052] Reference Figure 8As an embodiment of the present invention, specifically, the transmission assembly 10 includes a fixed sleeve 101, a rotary vane 102, a long shaft 103, a third bevel gear 104, a fourth bevel gear 105 and a safety closing mechanism 106, the fixed sleeve 101 is mounted on the side wall of the protective cover 95, the rotary vane 102 is rotatably mounted on the top of the bar frame 93, the long shaft 103 is rotatably mounted on the inner periphery of the fixed sleeve 101, and the end of the long shaft 103 is connected to the rotating shaft of the spur gear 965, the third bevel gear 104 is mounted on the end of the long shaft 103, the fourth bevel gear 105 is mounted on the top of the rotary vane 102, and the fourth bevel gear 105 is meshed with the third bevel gear 104, and the safety closing mechanism 106 is mounted on the top of the fixed sleeve 101; incomplete reaction When the gas rises and passes through the rotor blade 102, it drives the rotor blade 102 and the fourth bevel gear 105 to rotate. The fourth bevel gear 105 drives the long shaft 103 to rotate through the third bevel gear 104 meshing therewith. The long shaft 103 drives the spur gear 965 to rotate. On the one hand, the spur gear 965 directly drives the rotating ring 92 to rotate through the annular strip 921, and on the other hand, it drives the second bevel gear 964 to rotate. The second bevel gear 964 drives the rubber wheel 963 to rotate through the first bevel gear 962 meshing therewith, so that the limit ring 91 moves up along the inner wall of the reactor body 1 with the rubber wheel 963, and then the safety closing mechanism 106 closes the end of the exhaust pipe 6 to prevent the unreacted hydrogen sulfide gas and sulfur dioxide gas from being discharged in large quantities.
[0053] Reference Figure 8 As an embodiment of the present invention, specifically, the safety closing mechanism 106 includes a safety rod 1061, a slide groove 1062, a slide rod 1063 and a suction cup 1064. The safety rod 1061 is installed on the top of the fixed sleeve 101, and the safety rod 1061 is located directly below the connection between the exhaust pipe 6 and the reactor body 1. The slide groove 1062 is constructed inside the safety rod 1061, the slide rod 1063 slides through the safety rod 1061, and the suction cup 1064 is installed on the top of the slide rod 1063.
[0054] Working principle: before injecting the reaction solution into the reactor body 1, start the reduction motor 4 to drive the transmission shaft 32 and the screw rod 33 to rotate clockwise, and through the cooperation of the screw rod 33 and the bar frame 93, the sulfur removal component 9 is moved up to a position above the liquid level. At this time, the bar frame 93 is separated from the screw rod 33, and then the reaction solution not higher than the bottom surface of the rotating ring 92 is injected into the reactor body 1, and the reaction solution is raised to a suitable temperature by the heater 7. When the hydrogen sulfide gas and sulfur dioxide gas at a certain rate are introduced into the reactor body 1 to react with the solution; if the gas sensor 61 detects When it is detected that gas is discharged from the exhaust pipe 6, it means that the solution concentration is reduced at this time, and the hydrogen sulfide gas and the sulfur dioxide gas have not reacted completely. The gas sensor 61 first closes the one-way valve 51 through the controller and the circuit board to stop the introduction of the hydrogen sulfide gas and the sulfur dioxide gas. In this process, when the unreacted gas passes through the transmission component 10, the gas drives the rotary blade 102 to rotate and provide power for the sulfur removal component 9, so that the limit ring 91 and the rotating ring 92 drive the safety closing mechanism 106 to move up together until the suction cup 1064 blocks the end of the exhaust pipe 6;
[0055] Specifically, when hydrogen sulfide gas and sulfur dioxide gas flow out from the corresponding surfaces of the stirring plate 34, the output shaft of the reduction motor 4 drives the stirring plate 34 to rotate continuously through the transmission shaft 32 and the screw 33. After the hydrogen sulfide gas and sulfur dioxide gas flow out from the air holes of the stirring plate 34, they are evenly contacted with the reaction solution. After the gas fully reacts with the reaction solution, it flows to the top of the solution. When the unreacted gas flows to the exhaust pipe 6, it passes through the rotary blade 102 and drives the rotary blade 102 to rotate. The rotary blade 102 also drives the fourth bevel gear 105 to rotate. The fourth bevel gear 105 drives the long shaft 103 to rotate through the third bevel gear 104 meshing therewith, and the long shaft 103 drives the spur gear 965 Rotate, the spur gear 965 directly drives the rotating ring 92 to rotate through the annular strip 921 on the one hand, and drives the second bevel gear 964 to rotate on the other hand. The second bevel gear 964 drives the rubber wheel 963 to rotate through the first bevel gear 962 meshing therewith, and the limit ring 91 moves up to the highest point along the inner wall of the reactor body 1 with the rubber wheel 963. During this process, the safety rod 1061 and the suction cup 1064 move up together until the suction cup 1064 fits with the end of the exhaust pipe 6, thereby closing the exhaust pipe 6 to prevent a large amount of hydrogen sulfide gas and sulfur dioxide gas from being discharged. At the same time, after the rotary blade 102 loses drive, it moves down to the initial height together with the limit ring 91 and the rotating ring 92 under the action of gravity;
[0056] When the gas is stopped, the solution in the reactor body 1 is discharged at the same time, and the reaction solution and the precipitate are discharged through the discharge pipe 8. As the solution is discharged, the pressure in the space above the solution decreases, and the suction cup 1064 is separated from the exhaust pipe 6 due to the pressure change. The reduction motor 4 is started counterclockwise, and the threaded connection with the bar frame 93 through the screw rod 33 makes the limit ring 91 fit the vertical bar 912 and the inner wall of the reactor body 1 and move downward at a uniform speed. Because the rubber wheel 963 fits the inner wall of the reactor body 1, the rubber wheel 963 rotates when the limit ring 91 moves downward, and the rubber wheel 963 drives the first bevel gear The wheel 962 rotates, and the first bevel gear 962 drives the rotating ring 92 to rotate in the corresponding direction through the second bevel gear 964 and the spur gear 965. When the limiting ring 91 moves downward, the sulfur particles adhered to the inner wall of the reactor body 1 are scraped off, and the sulfur particles in contact with the outer periphery of the rotating ring 92 are separated from the rotating ring 92 and the limiting ring 91 under the action of centrifugal force, thereby maintaining the cleanliness of the rotating ring 92, and then the scraped sulfur particles are discharged through the discharge pipe 8, and the limiting ring 91 and the rotating ring 92 are restored to a high position so that the next reactor can continue the production of sulfur.
