Description

Technical Field

[0001] The invention relates to the technical field of sulfur production, and in particular to an insoluble sulfur liquid-solid conversion system and a use method thereof. Background Art

[0002] Insoluble sulfur is a linear polymer generated by the ring-opening polymerization of ordinary sulfur above the critical temperature (159°C), also known as μ-shaped sulfur. In a natural gas purification plant, hydrogen sulfide is converted into sulfur by treating natural gas containing hydrogen sulfide. This method is an important source of sulfur. In the subsequent treatment of sulfur, it is polymerized by heating to turn it into a liquid state, which is insoluble sulfur. After that, it is rapidly cooled to form suitable granules, which is convenient for transportation and storage. When it is needed, the granular sulfur is heated to return to liquid and can be used.

[0003] The Chinese invention patent with announcement number: CN114436219B discloses a system and method for continuous quenching and crushing of insoluble sulfur.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] like Figures 1 to 3 As shown, an insoluble sulfur liquid-to-solid conversion system includes a stockpile 105, a parking lot 101, and an overflow trough 104. The parking lot 101 is at least ten meters higher than the stockpile 105. The parking lot 101 is used for parking transfer vehicles. The plane on the parking lot 101 for parking the transfer vehicles needs to be provided with a slope. The inclination angle of the slope needs to be 2 to 3 degrees. The lowest end of the slope faces the stockpile 105 to collect liquid materials in the transfer vehicles. A coolant water tank 102 is also provided on the stockpile 105. Coolant is provided in the coolant water tank 102. A cooling device is also provided in the coolant water tank 102 to cool the cooling liquid.

[0029] like Figures 1 to 3 As shown, a collecting trough 103 is also provided on the stockpile 105, and the collecting trough 103 is fixedly connected to the water inlet of the coolant tank 102. A collecting slope is provided on the collecting trough 103, and the highest end of the collecting slope is the side close to the stockpile 105, and the lowest end is the side of the water inlet on the coolant tank 102. A plurality of sedimentation ladders are provided in the collecting trough 103 for simple filtering of the coolant.

[0030] like Figures 1 to 3 As shown, a granulation tower 200 is arranged on the overflow trough 104, and an inclined slope is arranged on the overflow trough 104 to collect the coolant overflowing from the granulation tower 200, and the lowest end of the inclined slope on the overflow trough 104 is close to the collecting trough 103, so that the coolant overflowing from the granulation tower 200 can be collected in the collecting trough 103, and a collecting slope is arranged on the stockpile 105, and the lowest end of the collecting slope on the stockpile 105 is close to the collecting trough 103, so that the coolant on the stockpile 105 can be collected in the collecting trough 103.

[0031] like Figures 3 to 6As shown, the granulation tower 200 includes a support frame 201, and the support frame 201 is fixedly connected to the overflow trough 104. A lower tank body 202 is fixedly installed on the inner side of the support frame 201, and an upper tank body 203 is fixedly installed on the lower tank body 202. The lower tank body 202 and the upper tank body 203 form a cooling chamber, and a plurality of feed pipes 209 for feeding are fixedly installed on the upper tank body 203. The feed pipes 209 are fixedly connected to the parking lot 101, and a bellows 210 is fixedly installed at one end of the feed pipe 209 away from the upper tank body 203. The bellows 210 is a flexible pipe, and the other end of the bellows 210 can be connected to the unloading port of the transfer vehicle, so that the liquid sulfur will enter the cooling chamber through the bellows 210 and the annular pipe 207.

[0032] like Figures 2 to 5 As shown, an overflow water pipe 212 is also fixedly installed on one side of the lower tank body 202. The connection position between the overflow water pipe 212 and the lower tank body 202 is set at one end close to the upper tank body 203. The overflow water pipe 212 is used to prevent water in the cooling chamber from overflowing. The pipe outlet of the overflow water pipe 212 is set in the overflow trough 104. When the liquid in the cooling chamber overflows, the liquid will fall into the overflow trough 104 from the overflow water pipe 212, and then flow into the coolant tank 102 through the overflow trough 104 and the collecting trough 103.

[0033] like Figures 4 to 6 As shown, a plurality of cooling water pipes 211 are fixedly mounted on the lower tank body 202, and the lower tank body 202 is mounted in the middle of the lower tank body 202. The other end of the cooling water pipe 211 is connected to the water supply port of the coolant tank 102, so that the cooled coolant enters the cooling chamber to cool the liquid sulfur.

[0034] like Figures 4 to 6 As shown, a discharge pipe 214 is fixedly installed at one end of the lower tank body 202 away from the upper tank body 203, and the outlet end of the discharge pipe 214 is aligned with the stockpile yard 105. The liquid sulfur cooled by the lower tank body 202 will become solid sulfur, and the solid sulfur mixed with the coolant will flow out from the discharge pipe 214. The discharge pipe 214 is also provided with a discharge valve 213 to control the discharge time of the discharge pipe 214.

[0035] like Figure 6 to Figure 7 and Fig.12 As shown, a leakage barrel 216 is fixedly installed on the inner wall of the upper tank body 203, and a plurality of forming holes are arranged in the leakage barrel 216. The diameters of the plurality of forming holes are different. When the liquid sulfur passes through the forming holes of different diameters and then falls into the coolant in the cooling chamber, it is convenient for the liquid sulfur to form sulfur particles of different sizes. Here, the forming holes on the leakage barrel 216 can also be replaced with holes of different diameters according to actual use requirements.

[0036] like Figures 6 to 10 As shown, an intermediate ring 217 is rotatably mounted on one end of the leakage barrel 216 away from the lower tank body 202, and an upper fixed ring 215 is also rotatably mounted on the intermediate ring 217. The upper fixed ring 215 is fixedly connected to the inner wall of the upper tank body 203, and a bundle barrel 218 is also fixedly mounted in the upper fixed ring 215. The bundle barrel 218 is used to limit the flow of liquid sulfur. One end of the feed pipe 209 is arranged in the bundle barrel 218, so that the liquid sulfur will directly flow into the bottom of the leakage barrel 216 after flowing into the bundle barrel 218, and the bundle barrel 218 will not contact the leakage barrel 216.

[0037] like Figures 7 to 11 As shown, a main scraper 221 is fixedly mounted on the intermediate ring 217, a main motor 219 is fixedly mounted on the outer wall of the main scraper 221, a motor gear 220 is fixedly mounted on the output shaft of the main motor 219, an annular rack is arranged at one end of the leakage barrel 216 close to the upper fixed ring 215, the motor gear 220 is meshed with the annular rack on the leakage barrel 216, the main scraper 221 is also in close contact with the inner wall of the leakage barrel 216, an upper scraper 225 is also fixedly mounted on the main scraper 221, the upper scraper 225 is in close contact with the inner wall of the upper fixed ring 215, and an outer scraper 220 is also fixedly mounted on the main scraper 221 24. The outer scraper 224 is in close contact with the outer wall of the bundle barrel 218. When the main motor 219 is started, the motor gear 220 is meshed with the annular rack to allow the main scraper 221 to rotate on the leakage barrel 216. When the main scraper 221 is driven to rotate between the leakage barrel 216 and the upper fixed ring 215, the main scraper 221 will scrape off the solid sulfur on the inner walls of the leakage barrel 216 and the upper fixed ring 215 and the outer wall of the bundle barrel 218 to prevent sulfur from adhering to the work. The inner wall of the bundle barrel 218 is always in a high temperature state because liquid sulfur is continuously poured into it. Therefore, not too much sulfur will be adsorbed on the inner wall of the bundle barrel 218.

[0038] like Figures 6 to 10 As shown, an inner belt 222 is also provided on the output shaft of the main motor 219, and a discharge valve 213 is also rotatably installed on the main scraper 221. A stainless steel brush is provided on the outer wall of the discharge valve 213. The other end of the inner belt 222 is provided on the cleaning rod 223 to drive the cleaning rod 223 to rotate. The rotation ratio of the output shaft of the main motor 219 and the cleaning rod 223 is three to one. This is to allow the cleaning rod 223 to rotate faster while following the main scraper 221 around the axis of the leakage barrel 216, thereby cleaning the forming holes on the leakage barrel 216.

[0039] like Figures 6 to 8 and Fig.12As shown, an intermediate shaft 226 is rotatably mounted on the leakage barrel 216, and the intermediate shaft 226 is arranged in the cooling chamber. A large scraper 227 is fixedly mounted on the intermediate shaft 226, and the large scraper 227 is in close contact with the inner wall of the lower tank body 202. The intermediate shaft 226 is also rotatably connected to the cleaning rod 223. When the cleaning rod 223 rotates around the axis of the leakage barrel 216, it will also rotate with the intermediate shaft 226, so that the intermediate shaft 226 can clean the inner wall of the lower tank body 202 and the bottom of the lower tank body 202 through the large scraper 227 to prevent excessive sulfur from solidifying on the inner wall of the lower tank body 202.

[0040] like Figures 5 to 8 As shown, a shunt pipe 206 is fixedly installed on the inner wall of one end of the upper tank body 203 away from the lower tank body 202, and a plurality of dust suppression water pipes 208 are fixedly installed on the shunt pipe 206. A plurality of purification nozzles are arranged on the dust suppression water pipe 208. The dust suppression water pipe 208 is fixedly connected to the inner wall of the upper tank body 203. An annular pipe 207 is fixedly installed on one end of the shunt pipe 206 arranged outside the upper tank body 203. The other end of the annular pipe 207 is connected to the cooling The water supply port of the liquid water tank 102 is connected to allow the cooled coolant to pass through the purification nozzle on the dust reduction water pipe 208 to reduce dust and cool the cooling chamber, so that particulate matter or heat in the cooling chamber cannot leave. A ventilation pipe 204 is fixedly installed at one end of the upper tank body 203 away from the lower tank body 202. The ventilation pipe 204 is used to allow air flow. A ventilation fan 205 is provided on the ventilation pipe 204 to discharge the air flow in the cooling chamber from the inside to the outside.

[0041] The present invention also provides a method for using the insoluble sulfur liquid-solid conversion system, comprising the following steps: S10: Connecting the support frame 201 on the granulation tower 200 to the discharge port on the transfer vehicle; S20: Start the coolant tank 102, and allow the coolant in the coolant tank 102 to enter the granulation tower 200 through the cooling water pipe 211; S30: When the liquid in the granulation tower 200 begins to overflow from the overflow pipe 212, the discharge valve 213 on the granulation tower 200 is rotated to open the discharge pipe 214; S40: opening the discharge port valve on the transfer vehicle to allow the liquid sulfur to enter the granulation tower 200 for cooling and granulation; S50: The sulfur particles flow out of the granulation tower 200 from the discharge pipe 214 and fall onto the stockpile 105 after being mixed with the coolant. The coolant will be collected in the collection tank 103 and then flow into the coolant water tank 102 for circulation. S60: The main motor 219 is started at a fixed time to rotate the main scraper 221, and the cooling water pipe 211 rotates to clean the forming holes on the leakage barrel 216 through the cleaning rod 223 to prevent the forming holes from being blocked.

[0042] Working principle: When using this device, it is necessary to first confirm whether there is enough coolant in the coolant tank 102, and then drive the transfer vehicle to the parking lot 101. At this time, through the slope set on the parking lot 101, the front of the transfer vehicle is in a high position, and the unloading port of the transfer vehicle is in a low position. Then, one end of the bellows 210 is connected to the unloading port of the transfer vehicle. After connection, do not open the unloading valve. It is necessary to confirm whether the coolant in the lower tank 202 is stored at a predetermined height.

[0043] The coolant in the lower tank body 202 passes through the coolant water tank 102 and then enters the coolant water tank 102 and the annular tube 207. At this time, it is necessary to first close the channel at the discharge pipe 214 by rotating the discharge valve 213, so that the coolant can accumulate in the cooling chamber. It is worth noting here that the height of the coolant must reach the overflow water pipe 212 to be appropriate. When the coolant is continuously injected into the overflow water pipe 212, when the overflow water pipe 212 overflows the coolant, the discharge valve 213 can be opened to release the coolant, and then the discharge valve on the transfer vehicle can be opened to allow liquid sulfur to enter the cooling chamber through the bellows 210 and the feed pipe 209. At this time, the liquid sulfur in the transfer vehicle is 130-155 degrees Celsius, so after the sulfur liquid enters the cooling chamber, the liquid sulfur will fall into the leakage barrel 216, and then fall into the coolant after passing through the forming hole in the leakage barrel 216 In the process, liquid sulfur will turn into solid due to the drop in temperature, and the solid sulfur is heavier than the coolant, so the sulfur liquid will gather at the discharge pipe 214. When the sulfur particles enter the discharge pipe 214, they will be tilted into the stockpile 105 together with the coolant. Due to the collection slope set on the stockpile 105, the coolant will flow to the lowest point of the stockpile 105 at this time, and the sulfur particles will remain in place waiting for processing. In the process of work, it is only necessary to use machinery to continuously remove the sulfur particles at the discharge port of the discharge pipe 214, and the coolant gathered in the stockpile 105 will flow into the collection tank 103, and the coolant will be filtered through the sedimentation ladder on the collection tank 103 to prevent too many sulfur particles from entering the coolant water tank 102. The coolant entering the coolant water tank 102 will be cooled by the cooling equipment for subsequent recycling.

[0044] When liquid sulfur enters the granulation tower 200, the coolant in the coolant water tank 102 will also enter the dust suppression water pipe 208 through the annular pipe 207, and then the coolant will be sprayed into the upper tank body 203 through the purification nozzle on the dust suppression water pipe 208, so that the high temperature brought by the liquid sulfur in the leakage barrel 216 can be reduced. This is to prevent the steam generated by the liquid sulfur from escaping from the granulation tower 200 with some sulfur. When the high-temperature gas of liquid sulfur rises in the leakage barrel 216, the sprayed coolant will cool down these gases and the sulfur carried in the cooling gas at the same time, so that these sulfur vapors will form sulfur particles after cooling and fall back into the cooling chamber, and the gas that has passed through the coolant will overflow from the granulation tower 200 through the ventilation pipe 204.

[0045] In the process of liquid sulfur entering the granulation tower 200, the main motor 219 can be started regularly to drive the main scraper 221 and the intermediate ring 217 to rotate through the motor gear 220. The main scraper 221 will allow the cleaning rod 223 to rotate during the rotation process, so that the stainless steel brush on the cleaning rod 223 can clean the forming holes of different sizes on the leakage barrel 216, thereby preventing the forming holes from being blocked and causing the liquid sulfur to accumulate in the leakage barrel 216. When the main scraper 221 rotates, the cleaning rod 223 can rotate on its own. The inner wall of the leaking barrel 216 will be cleaned at the same time. At the same time, the outer scraper 224 will clean the outer wall of the bundle barrel 218 when the leaking barrel 216 rotates. At the same time, the upper scraper 225 will clean the inner wall of the upper fixed ring 215. Most of the sulfur on the inner wall of the upper fixed ring 215 is formed when the steam generated by liquid sulfur passes through. When the intermediate shaft 226 rotates, the large scraper 227 will continuously contact the inner wall of the tank body 202, thereby cleaning the sulfur on the inner wall of the large scraper 227. The above description is only a preferred embodiment of the present invention, and is not intended to limit the protection scope of the present invention.
