Description

Technical Field

[0001] The present application relates to the technical field of sulfuric acid production, and in particular to a recovery device. Background Art

[0002] The current method of recovering sublimated sulfur is to first cool the gas phase to condense the sublimated sulfur in the gas phase into sulfur dust, then use a metal mesh to capture the sulfur dust, and then heat the collected sulfur dust to make it melt and drip for recovery.

[0003] Since sulfur dust easily blocks the pores of the metal mesh and affects the gas flow, the metal mesh needs to be suspended for cleaning after a period of use before it can be recycled. In addition, some small-particle sulfur dust easily escapes from the pores of the metal mesh. If more sulfur dust needs to be captured, the mesh size of the metal mesh needs to be increased. The larger the mesh size, the finer the wire diameter, and the easier it is for the metal mesh to corrode and fail. Therefore, it needs to be replaced frequently, which also affects the recycling progress. Therefore, the recycling efficiency of the above-mentioned sublimated sulfur recovery method is low.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] The sulfuric acid production process requires solid sulfur to be melted and then put into diatomaceous earth for filtering in a filter. After filtering, the diatomaceous earth, solid impurities and part of the sulfur are discharged as sulfur slag. The sulfur slag is then put into a heating kettle for heating and stirring to allow the sulfur in the sulfur slag to sublime and be extracted with the gas phase. The collected sublimated sulfur is then cooled and recovered.

[0037] The current method of recovering sublimated sulfur is to first cool the gas phase to condense the sublimated sulfur in the gas phase into sulfur dust, then use a metal mesh to capture the sulfur dust, and then heat the collected sulfur dust to melt and drip for recovery.

[0038] Since sulfur dust easily blocks the pores of the metal mesh and affects the gas flow, the metal mesh needs to be suspended for cleaning after a period of use before it can be recycled. In addition, some small-particle sulfur dust easily escapes from the pores of the metal mesh. If more sulfur dust needs to be captured, the mesh size of the metal mesh needs to be increased. The larger the mesh size, the finer the wire diameter, and the easier it is for the metal mesh to corrode and fail. Therefore, it needs to be replaced frequently, which also affects the recycling progress. Therefore, the recycling efficiency of the above-mentioned sublimated sulfur recovery method is low.

[0039] like Figure 1 As shown, in order to solve the above technical problems, an embodiment of the present application provides a recovery device 100, which relates to the technical field of sulfuric acid production and is mainly used for recovering sublimated sulfur (ie, gaseous sulfur).

[0040] like Figures 1 to 3As shown, the recovery device 100 provided in this embodiment includes: a cooling component 110, a flow rotating disk 120, a sulfur separation plate 130, a scraper 140 and a driving component 150.

[0041] Among them, the sulfur analysis plate 130 is rotatably arranged between the cooling component 110 and the flow rotating disk 120, and the cooling component 110 is used to cool the sulfur analysis plate 130. The sulfur analysis plate 130 and the flow rotating disk 120 jointly define a sealed sulfur analysis chamber 1211. The flow rotating disk 120 is respectively provided with an air inlet 1212, an air outlet 1213 and a feed port 1214, and the air inlet 1212, the air outlet 1213 and the feed port 1214 are respectively connected to the sulfur analysis chamber 1211, and the air inlet 1212 is used to input sublimated sulfur into the sulfur analysis chamber 1211. The scraper 140 is located at the feed port 1214 and is connected to the flow rotating disk 120. The scraper 140 abuts against the side of the sulfur analysis plate 130 away from the cooling component 110. The driving component 150 is connected to the sulfur analysis plate 130, and is used to drive the sulfur analysis plate 130 to rotate between the cooling component 110 and the flow rotating disk 120.

[0042] It should be noted that the gas outlet 1213 is used to discharge the remaining sublimated sulfur to maintain a balanced air pressure in the sulfur separation chamber 1211. The cooling assembly 110 can cool the sulfur separation plate 130 to reduce the temperature of the sulfur separation plate 130 to below 70°, so that the sublimated sulfur can easily precipitate sulfur powder attached to the sulfur separation plate 130.

[0043] It is understandable that when the recovery device 100 provided in this embodiment is used, the air inlet 1212 inputs sublimated sulfur into the sulfur analysis chamber 1211, and the sulfur analysis plate 130 is in a low temperature state under the cooling of the cooling component 110, and the sublimated sulfur input into the sulfur analysis chamber 1211 can be cooled, so that the sublimated sulfur precipitates sulfur powder and adheres to the sulfur analysis plate 130. As the driving component 150 drives the sulfur analysis plate 130 to rotate, the precipitated sulfur touches the scraper 140 and falls into the feed port 1214, realizing the recovery of the sublimated sulfur. Compared with the method of using a metal mesh to capture and heat the sublimated sulfur for recovery, sulfur can be precipitated over a large area through the sulfur analysis plate 130, which has stronger corrosion resistance, and the recovery process can be carried out continuously, so it has a higher recovery efficiency.

[0044] like Figure 2 and Figure 3As shown, in one embodiment, the flow rotating disk 120 includes a disk body 121, a first upper extension portion 122 and a second upper extension portion 123, the disk body 121 is respectively provided with an air inlet 1212, an air outlet 1213 and a feed port 1214, the first upper extension portion 122 and the second upper extension portion 123 are respectively arranged on the side of the disk body 121 facing the cooling assembly 110, the disk body 121, the first upper extension portion 122 and the second upper extension portion 123 jointly define a liquid sealing groove 1215, and the liquid sealing groove 1215 is filled with a sealing medium. The sulfur separation plate 130 includes a sulfur separation portion 131 and a lower extension portion 132. The sulfur separation portion 131 is rotatably arranged between the cooling assembly 110 and the second upper extension portion 123, and the sulfur separation portion 131, the second upper extension portion 123 and the disk body portion 121 jointly define a sulfur separation cavity 1211. The lower extension portion 132 is annularly arranged on the side of the sulfur separation portion 131 away from the cooling assembly 110, and at least a portion of the lower extension portion 132 is located in the liquid sealing groove 1215.

[0045] For example, the sealing medium may be selected from water, oil, or other flowing substances that can block gas.

[0046] In this embodiment, a sulfur separation chamber 1211 is defined by the sulfur separation portion 131, the second upper extension portion 123 and the disk body portion 121, and a liquid sealing groove 1215 is defined by the disk body portion 121, the first upper extension portion 122 and the second upper extension portion 123. At least part of the lower extension portion 132 is located in the liquid sealing groove 1215, and the liquid sealing groove 1215 is filled with a sealing medium, which can achieve a relative sliding sealing connection between the bottom of the sulfur separation plate 130 and the top of the flow rotating disk 120, thereby reducing the possibility of leakage of sublimated sulfur in the sulfur separation chamber 1211, thereby improving the recovery efficiency of the sublimated sulfur.

[0047] Of course, for the above embodiment, a sealing ring can be provided between the edge of the sulfur separation plate 130 and the edge of the flow disk 120 to achieve a relative sealed sliding connection between the two, and the sealing of the sulfur separation chamber 1211 can also be achieved. No specific restrictions are made on the relative sealing method between the sulfur separation plate 130 and the flow disk 120.

[0048] like Figure 4 As shown, in one embodiment, the scraper 140 includes a plate body 141 and a heating element 142. The plate body 141 is located at the discharge port 1214 and is connected to the flow turntable 120. The plate body 141 abuts against the side of the sulfur separation plate 130 away from the cooling assembly 110. The heating element 142 is arranged inside the plate body 141 for heating the plate body 141.

[0049] Exemplarily, the heating element 142 may be a component that can convert electrical energy into thermal energy, such as an electric heating wire, a ceramic heating plate, or an electric heating film.

[0050] In this embodiment, the temperature of the plate body 141 can be maintained between 119° and 121° by heating the heating element 142, so that the sulfur powder on the sulfur separation plate 130 can be heated into liquid sulfur, but the sulfur powder will not be converted back into gaseous sulfur. This makes it easier to scrape the sulfur powder to the discharge port 1214, thereby improving the recovery efficiency of the sublimated sulfur.

[0051] Illustratively, under the heating of the heating element 142, the temperature of the plate body 141 can be maintained at any value among 119°, 119.5°, 120°, 120.3°, 121° or any value in a range consisting of any two of them. No specific limitation is made to the temperature of the plate body 141 herein.

[0052] Of course, for the above embodiment, the heating element 142 may be eliminated, that is, the scraper 140 does not have a heating effect, and the sulfur powder precipitated on the sulfur separation plate 130 can also be scraped off by relying only on the plate body 141 .

[0053] like Figure 1 and Figure 2 As shown, in one embodiment, the cooling assembly 110 includes a liquid inlet pipe 111, a liquid outlet pipe 112 and a cooling box 113. The cooling box 113 has a cooling cavity 11311. The liquid inlet pipe 111 and the liquid outlet pipe 112 are respectively arranged in the cooling box 113. The liquid inlet pipe 111 is used to input cooling medium into the cooling cavity 11311, and the liquid outlet pipe 112 is used to output cooling medium. The bottom of the cooling box 113 is attached to the sulfur separation plate 130.

[0054] Exemplarily, the cooling medium may be a liquid substance capable of cooling the temperature, such as cooling water or cooling oil. The temperature of the cooling medium may be 35° to 40°, for example, any value among 35°, 36°, 37°, 37.5°, 38°, 40°, or any value in a range consisting of any two of them, and no specific limitation is imposed on the temperature of the cooling medium.

[0055] In this embodiment, the cooling medium is input into the cooling chamber 11311 through the liquid inlet pipe 111, so that the temperature of the cooling box 113 can be reduced, and the bottom of the cooling box 113 is attached to the sulfur separation plate 130, so that the cold energy can be transferred to the sulfur separation plate 130, thereby cooling the sulfur separation plate 130. In this way, the sublimated sulfur can precipitate sulfur powder on the sulfur separation plate 130, which is convenient for the scraper 140 to scrape the sulfur powder to the discharge port 1214.

[0056] like Figure 2As shown, further, the driving assembly 150 includes a driving member 151 and a rotating shaft 152. The driving member 151 is arranged above the cooling box 113. One end of the rotating shaft 152 is connected to the output end of the driving member 151. The rotating shaft 152 is rotatably arranged in the cooling box 113 away from the driving member 151 and is connected to the sulfur separation plate 130. The driving member 151 is used to drive the rotating shaft 152 to rotate relative to the cooling box 113 to drive the sulfur separation plate 130 to rotate between the cooling assembly 110 and the flow disk 120.

[0057] like Figure 2 As shown, for example, the driving member 151 can be set on the bracket 174, and the bracket 174 is connected to the top of the cooling box 113 through the fixing member 175, so as to realize that the driving member 151 is set above the cooling box 113. In addition, the driving member 151 can select a rotating motor, a driving motor or other components capable of outputting torque.

[0058] In this embodiment, the rotating shaft 152 is rotatably provided in the cooling box 113 and connected to the sulfur separation plate 130. Under the drive of the driving member 151, the rotating shaft 152 can drive the sulfur separation plate 130 to rotate between the cooling assembly 110 and the flow disk 120, that is, rotate relative to the cooling assembly 110 and the flow disk 120, so that as the sulfur separation plate 130 rotates, the scraper 140 can scrape the sulfur powder precipitated on the sulfur separation plate 130 into the discharge port 1214. At the same time, the rotating shaft 152 is provided in the cooling box 113, and the driving member 151 is provided above the cooling box 113, which can reduce the occupied space of the driving assembly 150, which is conducive to the compact design of the recovery device 100.

[0059] like Figure 2 As shown, further, the cooling box 113 includes a box body 1131 and a sleeve 1132, the box body 1131 has a cooling cavity 11311, the sleeve 1132 is penetrated in the cooling cavity 11311 and is integrally connected with the box body 1131, and the rotating shaft 152 is rotatably penetrated in the sleeve 1132.

[0060] In this embodiment, since the sleeve 1132 is inserted into the cooling chamber 11311 and is integrally connected to the box body 1131, effective sealing can be achieved between the sleeve 1132 and the box body 1131 to prevent the rotating shaft 152 from contacting the cooling medium in the box body 1131 and causing damage, thereby reducing the failure rate of the recovery device 100.

[0061] In another embodiment, the cooling assembly 110 includes a liquid inlet joint, a liquid outlet joint and a liquid cooling plate, the liquid cooling plate defines a cooling cavity 11311, the liquid inlet joint is arranged at one end of the liquid cooling plate, and is used to input a cooling medium into the cooling cavity 11311, the liquid outlet joint is arranged at one end of the liquid cooling plate away from the liquid inlet joint, and is used to output the cooling medium, and the liquid inlet joint and the liquid outlet joint are respectively connected to a cooling medium supply device, so as to realize the circulation of the cooling medium in the cooling cavity 11311. In this embodiment, the sulfur separation plate 130 can also be cooled by the liquid cooling plate, so that sulfur powder is precipitated after the sublimated sulfur contacts the sulfur separation plate 130, and no specific limitation is made to the structure of the cooling assembly 110.

[0062] like Figure 3 As shown, in one embodiment, the feed opening 1214 and the scraper 140 are sequentially distributed along the rotation direction of the sulfur separation plate 130 , and the scraper 140 is located at the edge of the feed opening 1214 .

[0063] In this embodiment, since the feed port 1214 and the scraper 140 are distributed in sequence along the rotation direction of the sulfur separation plate 130, and the scraper 140 is located at the edge of the feed port 1214, it is convenient for the scraper 140 to scrape off the sulfur powder over a large area, and the scraped sulfur powder is gathered above the feed port 1214 for easy recovery.

[0064] like Figure 3 As shown, further, the air inlet 1212 is located on the side of the scraper 140 away from the discharge port 1214, and the air outlet 1213 is located on the side of the scraper 140 away from the air inlet 1212, that is, the air inlet 1212 and the air outlet 1213 are respectively located on two opposite sides of the scraper 140, so that the scraper 140 can not only scrape off the sulfur powder, but also prevent the sublimated sulfur that enters the sulfur separation chamber 1211 from the air inlet 1212 from taking a shortcut and being discharged from the air outlet 1213, so that the sublimated sulfur must bypass the scraper 140 to reach the air outlet 1213, thereby extending the flow path of the sublimated sulfur. In this way, the precipitation rate of the sublimated sulfur after contacting the sulfur separation plate 130 can be improved, and the loss caused by the large amount of sublimated sulfur discharged from the air outlet 1213 can be reduced.

[0065] In another embodiment, the scraper 140 is arranged at the middle position of the discharge port 1214, that is, there is an overlapping part between the scraper 140 and the discharge port 1214, so that the scraper 140 can also scrape the sulfur powder to the discharge port 1214, and no specific limitation is made on the relative position relationship between the discharge port 1214 and the scraper 140.

[0066] like Figure 1 and Figure 2As shown, in one embodiment, the recovery device 100 further includes a sulfur storage box 160 having a sulfur storage cavity 161 . The sulfur storage box 160 is disposed below the flow turntable 120 , and the discharge port 1214 is connected to the sulfur storage cavity 161 .

[0067] In this embodiment, the sulfur powder scraped off by the scraper 140 falls into the sulfur storage chamber 161 through the discharge port 1214 , so that the sulfur powder is collected by the sulfur storage box 160 .

[0068] like Figure 2 As shown, further, the sulfur storage box 160 is provided with an opening 162 communicating with the sulfur storage cavity 161 , and a door panel 163 detachably connected to the sulfur storage box 160 is provided at the opening 162 .

[0069] In this embodiment, when a certain amount of sulfur powder is collected in the sulfur storage box 160 , the door panel 163 can be removed, and the collected sulfur powder can be taken out through the opening 162 and transported to the next use location.

[0070] like Figure 1 and Figure 3 As shown, in one embodiment, the recovery device 100 also includes an air inlet pipe 171, an air outlet pipe 172 and a collecting bag 173. The air inlet pipe 171 is located below the flow disk 120 and is arranged at the air inlet 1212. The air outlet pipe 172 is located below the flow disk 120 and is arranged at the air outlet 1213. The collecting bag 173 is connected to one end of the air outlet pipe 172 away from the air outlet 1213.

[0071] In this embodiment, the air inlet pipe 171 is provided to facilitate the input of sublimated sulfur, that is, gaseous sulfur, into the sulfur separation chamber 1211, and the collecting bag 173 is provided at one end of the air outlet pipe 172 away from the air outlet 1213 to collect the sublimated sulfur remaining after being precipitated by the sulfur separation plate 130. In addition, the remaining sublimated sulfur can be re-input into the sulfur separation chamber 1211 through the air inlet pipe 171 for precipitation.

[0072] In summary, the working principle of the recovery device 100 provided in the embodiment of the present application is as follows: the liquid inlet pipe 111 inputs a cooling medium into the cooling box 113, the cooling box 113 transfers the cold of the cooling medium to the sulfur separation plate 130, the air inlet pipe 171 inputs sublimated sulfur into the sulfur separation chamber 1211, the sublimated sulfur flows in the sulfur separation chamber and contacts the sulfur separation plate 130, and then cools down and precipitates sulfur powder attached to the bottom of the sulfur separation plate 130, the driving member 151 drives the rotating shaft 152 to rotate relative to the cooling box 113, so as to drive the sulfur separation plate 130 to rotate relative to the cooling box 113 and the flow turntable 120, and as the sulfur separation plate 130 rotates, the scraper 140 scrapes the precipitated sulfur powder to the discharge port 1214, thereby entering the sulfur storage chamber 161 and being collected by the sulfur storage box 160, thereby completing the recovery process of the sublimated sulfur.
