Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sulfur production equipment, in particular to a sulfur vapor condensing device. BACKGROUND

[0002] In the gasification and condensation stage of crude sulfur purification, liquid sulfur is heated to 445℃, and then gasified into sulfur vapor, and then condensed into 140-160℃ liquid sulfur through a condenser, and then granulated or flaked sulfur products are produced through a granulator.

[0003] Generally, water or air is used for condensing sulfur vapor, and the condensation heat of sulfur vapor is transferred to cooling water or air to be taken away. The water condensing method has the problems of uneven cooling, unstable temperature of liquid sulfur, resulting in too low temperature of sulfur (sulfur melting point 114.5-119℃), easy to block the condenser, too high temperature (self-ignition temperature 248-266℃), and easy to cause self-ignition of liquid sulfur. The water cooling method increases the consumption of cooling water, and the condensation heat of sulfur is also wasted.

[0004] For example, the Chinese patent document with publication number CN106698363B discloses a method for preparing an insoluble sulfur evaporation device, which comprises the following steps: first, using inert gas nitrogen to purge the saturated vapor heating kettle assembly, the superheater, the superheated sulfur vapor intermediate tank and the sulfur powder storage tank for 5-8 minutes; then injecting sulfur powder into the storage tank, and at the same time, injecting saturated steam into the saturated steam heating coil, heating the saturated steam heating kettle to keep the temperature at 180-190℃, and injecting high-temperature flue gas into the hot air heating jacket to heat the hot air heating furnace to a temperature of 460-480℃.

[0005] Step two, start the gas powder control system, use inert gas nitrogen as the protective gas, set the nitrogen output pressure to 0.4MPa, adjust the nitrogen flow, and according to the design production efficiency requirement, inject the sulfur powder into the saturated steam heating kettle body through the saturated steam heating kettle assembly inlet at a uniform speed, rotate the distributor and stirring paddle of the stirring assembly to make the sulfur powder uniformly fall into the saturated steam heating coil contact surface and be heated, the sulfur powder is converted into molten state, the liquid sulfur is heated by the transpiration effect and enters the distribution ring pipe along the transpiration convection pipe, guides the liquid sulfur to be sprayed to the hot air heating furnace body inner wall circumferential tangent direction, and is heated at 460-480℃ high temperature to rapidly gasify to form a gas-liquid mixture, the gas-liquid mixture flows along the hot air heating furnace body inner wall spiral downward, the liquid phase part is thrown to the hot air heating furnace body wall to continue evaporation under the action of cyclone separation, the gas phase part is enriched to the top of the hot air heating furnace body, and the liquid phase part which is not completely evaporated is enriched at the bottom of the hot air heating furnace body and returns to the saturated steam heating kettle body through the circulating convection pipe, and the gas phase part (superheated sulfur vapor) enters the superheated sulfur vapor conveying pipe through the gas-liquid separator, and the superheated sulfur vapor enters the superheated sulfur vapor intermediate tank for storage through the hot sulfur vapor pipe, and the storage pressure of the superheated sulfur vapor intermediate tank is set to 0.4MPa.

[0006] Step three, the sulfur fluid returned to the saturated steam heating kettle body through the circulating convection pipe is a gas-liquid mixture of enriched liquid phase, which sweeps the injected sulfur powder from bottom to top in the saturated steam heating kettle body to form a mixed fluid in convection, and fully contacts with the saturated steam heating coil heated surface under the help of the distributor and stirring paddle of the stirring assembly, so that the sulfur fluid obtains sufficient mass transfer and heat transfer, and then enters the hot air heating furnace body through the transpiration convection pipe and the distributor assembly to form a closed fluid circulation loop, thereby realizing the preparation of sulfur vapor into sulfur liquid.

[0007] In the above related technology, although the sulfur vapor can be prepared into sulfur liquid, the cooling medium is introduced from the bottom of the vapor kettle body, the cooling medium moves upward, the gaseous sulfur flows downward, and heat exchange is carried out in the vapor kettle body at this time, in the process of heat exchange, the temperature of the cooling medium flowing upward gradually increases, the temperature of the cooling medium flowing to the uppermost part is the highest, but due to the unstable temperature of the liquid sulfur, the temperature of the sulfur is too low (sulfur melting point 114.5-119℃), the heat exchange pipe in the reaction kettle is easy to be blocked, and the staff needs to clean the heat exchange pipe in the vapor kettle body regularly at this time, which causes the production efficiency of the sulfur liquid to decrease. SUMMARY

[0008] The present application provides a sulfur vapor condensing device, which aims to solve the problem of reducing the blockage of the heat exchange pipe in the vapor kettle body in the related technology.

[0009] The sulfur vapor condensing device provided by the present application adopts the following technical scheme:

[0010] The sulfur vapor condensing device comprises a vapor kettle body, a first heat exchange pipe arranged on the vapor kettle body, and a second heat exchange pipe sleeved on the first heat exchange pipe. The vapor kettle body is internally provided with a first mounting plate, a second mounting plate, a third mounting plate, a fourth mounting plate and a fifth mounting plate. The first mounting plate is arranged at the uppermost position of the vapor kettle body, and the first heat exchange pipe is fixed on the first mounting plate. The second mounting plate is arranged below the first mounting plate. The second heat exchange pipe is slidably connected to the second mounting plate. The second heat exchange pipe is provided with a first liquid inlet and a second liquid inlet. The third mounting plate and the fourth mounting plate form a liquid inlet chamber. The first liquid inlet is between the third mounting plate and the fourth mounting plate. The fifth mounting plate is used for plugging the second liquid inlet. When the second heat exchange pipe moves towards the first mounting plate, the second liquid inlet is between the fourth mounting plate and the fifth mounting plate, and the first liquid inlet is plugged by the third mounting plate.

[0011] By adopting the above technical scheme, the cooling liquid enters the liquid inlet chamber, the cooling liquid in the liquid inlet chamber enters the second heat exchange pipe through the first liquid inlet, and the sulfur vapor enters the first heat exchange pipe. Since the second heat exchange pipe is sleeved on the first heat exchange pipe, the flowing cooling liquid can exchange heat with the sulfur vapor in the first heat exchange pipe. The sulfur vapor after heat exchange becomes liquid, and the liquid sulfur is discharged from the vapor kettle body. The cooling liquid with high temperature is also discharged from the vapor kettle body. When one of the first heat exchange pipes is blocked, the second heat exchange pipe moves upwards. During the upward movement, the first liquid inlet is plugged by the third mounting plate, the second liquid inlet is opened, and the second heat exchange pipe with the plugged first liquid inlet cannot enter the cooling liquid. However, the cooling liquid with high temperature between the first mounting plate and the second mounting plate flows reversely, and the reversely flowing cooling liquid is discharged from the second liquid inlet. Since the reversely flowing cooling liquid has high temperature, the solid sulfur in the first heat exchange pipe can be further heated at this time. The heated sulfur becomes liquid and flows downward, thereby achieving the purpose of cleaning the solid sulfur in the first heat exchange pipe, reducing the shutdown frequency of the vapor kettle body, and improving the production efficiency of the sulfur vapor.

[0013] By adopting the above technical scheme, the mounting bracket is provided with the plugging assembly. The flow of the sulfur liquid in the first heat exchange pipe is detected by the plugging assembly. When the first heat exchange pipe is blocked, the flow of the sulfur liquid in the first heat exchange pipe decreases, and the opening of the lower end of the first heat exchange pipe also decreases.

[0015] By adopting the above technical scheme, in the process of normal falling of the sulfur liquid in the first heat exchange pipe, the falling thrust pushes the plugging plate to move downwards, and then the plugging spring is in a compressed state; when the sulfur liquid flow in the first heat exchange pipe becomes small, the flow pressure is smaller than the elastic force of the plugging spring, at this time, the plugging plate plugs the opening of the first heat exchange pipe, the mounting frame drives the second heat exchange pipe to move upwards, the second liquid inlet is opened in the process of moving upwards, the first liquid inlet is plugged, and the cooling liquid with a higher temperature at the upper portion moves downwards to heat the plugged first heat exchange pipe, at this time, the solid sulfur plugged in the first heat exchange pipe can be melted into liquid, so that the first heat exchange pipe is conveniently cleaned.

[0016] Optionally, the control assembly comprises a control rod slidingly connected to the mounting frame and a control spring fixed to the control rod, one end of the control spring away from the control rod is fixed to the mounting frame, and the control spring pushes the control rod to extend out of the mounting frame, and the plugging plate is fixedly provided with a pressing rod, the pressing rod moves downwards to push the control rod to move towards the direction close to the shaft center of the fifth mounting plate.

[0017] By adopting the above technical scheme, when the sulfur liquid flow in the first heat exchange pipe becomes slow, the pressure of the falling sulfur liquid is smaller than the elastic force of the plugging spring, the pressing rod does not push the control rod to move, the control rod extends out of the mounting frame, and then the control rod can be directly pushed to move, in the process of moving of the control rod, the mounting frame and the second heat exchange pipe provided on the mounting frame are driven to move upwards, so that the positions of the first liquid inlet and the second liquid inlet are conveniently adjusted.

[0018] Optionally, an inclined surface is arranged on the surface of the control rod close to the first mounting plate, and the height edge of the inclined surface close to the shaft center position of the second heat exchange pipe gradually decreases. By adopting the above technical scheme,

[0019] By adopting the above technical scheme, since the surface of the control rod close to the first mounting plate is arranged as an inclined surface, the plugging plate and the pressing rod abut against the inclined surface in the process of moving downwards, and then the control rod can be pushed to move towards the shaft center of the fifth mounting plate, at this time, the control rod does not extend out of the mounting frame.

[0020] Optionally, a driving assembly is arranged on the steam kettle body, the driving assembly is used to push the control rod to move upwards, and the control rod pushes the mounting frame to move upwards in the process of moving upwards.

[0021] By adopting the technical scheme, when the second heat exchange pipe needs to move upward, the control rod is pushed upward by the driving assembly, the control rod cannot slide on the mounting frame, and the control rod drives the mounting frame to move upward, the second heat exchange pipe is pushed to move upward in the process of moving upward of the mounting frame, and thus the second heat exchange pipe is conveniently adjusted.

[0022] Optionally, the driving assembly comprises a driving ring slidingly connected in the steam kettle body, a driving rod fixed on the driving ring, and a driving cylinder fixed on the steam kettle body, and a piston rod of the driving cylinder is fixed on the driving ring.

[0023] By adopting the technical scheme, when the sulfur steam is condensed, the driving cylinder drives the driving ring to move upward periodically, the driving ring drives the driving rod to move upward, the control rod extending from the mounting frame is pushed to move upward in the process of moving upward, the control rod drives the mounting frame and the second heat exchange pipe arranged on the mounting frame to move, and thus the purpose of driving the second heat exchange pipe to move is achieved.

[0024] Optionally, a plurality of driving rods are arranged, and the plurality of driving rods and the plurality of control rods are one-to-one corresponding.

[0025] By adopting the technical scheme, under the action of the plurality of control rods and the plurality of driving rods, the mounting frame and the second heat exchange pipe are more stably pushed to move.

[0026] Optionally, an upper end of the mounting frame is fixedly installed with a limiting ring, and the limiting ring abuts against an upper surface of the fifth mounting plate.

[0027] By adopting the technical scheme, the mounting frame is limited by the limiting ring, and thus the stability of the second heat exchange pipe is improved.

[0028] Optionally, a plurality of control assemblies are arranged, and a plurality of lower pressing rods are arranged, and the plurality of lower pressing rods and the plurality of control assemblies are one-to-one corresponding.

[0029] In summary, the present application has at least one of the following beneficial technical effects:

[0030] 1. When one of the first heat exchange pipes is blocked, the second heat exchange pipe is moved upward, the first liquid inlet is blocked by the third mounting plate in the process of moving upward, the second liquid inlet is opened, the second heat exchange pipe blocked by the first liquid inlet cannot enter the cooling liquid, and the cooling liquid with a higher temperature between the first mounting plate and the second mounting plate flows reversely, the reversely flowing cooling liquid is discharged from the second liquid inlet, the solid sulfur in the first heat exchange pipe is further heated at this time because the reversely flowing cooling liquid has a higher temperature, the heated sulfur flows downward in a liquid state, and thus the purpose of cleaning the solid sulfur in the first heat exchange pipe is achieved, the number of shutdowns of the steam kettle body is reduced, and the production efficiency of the sulfur steam is improved.

[0031] 2. When the flow rate of the sulfur liquid in the first heat exchange tube slows down, the downward pressure of the sulfur liquid is less than the elastic force of the sealing spring. The downward pressure rod will not push the control rod to move. The control rod will extend out of the mounting bracket and can then be directly pushed to move. During the movement of the control rod, the mounting bracket and the second heat exchange tube set on the mounting bracket will move upward, which facilitates the adjustment of the position of the first liquid inlet and the second liquid inlet.

Detailed Implementation

[0039] The following combination Figures 1-6 This application will be described in further detail.

[0040] During normal use, the steam vessel body 01 needs to be placed horizontally. However, in this application, in order to better describe the steam vessel body 01 and the various parts installed in the steam vessel body 01, the steam vessel body 01 is set vertically.

[0041] This application discloses a sulfur vapor condensation device. (Refer to...)Figures 1 to 6 The sulfur vapor condensing device comprises a vapor kettle body 01, a first heat exchange pipe 02 arranged on the vapor kettle body 01, and a second heat exchange pipe 03 sleeved on the first heat exchange pipe 02. The first heat exchange pipe 02 is arranged in plurality, and the second heat exchange pipe 03 is also arranged in plurality. The plurality of first heat exchange pipes 02 and the plurality of second heat exchange pipes 03 correspond one by one. An air inlet pipe 1 and a first liquid outlet pipe 11 are arranged on the vapor kettle body 01. The sulfur vapor can be introduced into the vapor kettle body 01 through the air inlet pipe 1 above. The sulfur vapor entering the vapor kettle body 01 will enter the first heat exchange pipe 02, and then the liquefied sulfur is discharged through the first liquid outlet pipe 11 below. A liquid inlet pipe 12 and a second liquid outlet pipe 13 are arranged on the vapor kettle body 01. The cooling liquid enters the second heat exchange pipe 03 through the liquid inlet pipe 12 below and is discharged through the second liquid outlet pipe 13 above. Through the arrangement of the first heat exchange pipe 02 and the second heat exchange pipe 03, the sulfur vapor can be heat exchanged. After the heat exchange is completed, the sulfur vapor becomes liquid and is discharged from the first liquid outlet pipe 11.

[0042] A first mounting plate 2 and a second mounting plate 21 are arranged in the vapor kettle body 01. The first mounting plate 2 is arranged at the uppermost of the vapor kettle body 01, and the first heat exchange pipe 02 is fixed on the first mounting plate 2. The second mounting plate 21 is arranged below the first mounting plate 2, and the second heat exchange pipe 03 is slidably connected to the second mounting plate 21. A first liquid inlet 3 is arranged on the second heat exchange pipe 03. In this embodiment, the air inlet pipe 1 is arranged above the first mounting plate 2, and the second liquid outlet pipe 13 is arranged between the first mounting plate 2 and the second mounting plate 21.

[0043] A third mounting plate 22, a fourth mounting plate 23 and a fifth mounting plate 24 are arranged in the vapor kettle body 01. The second heat exchange pipe 03 is also slidably connected to the third mounting plate 22, the fourth mounting plate 23 and the fifth mounting plate 24. The first mounting plate 2, the second mounting plate 21, the third mounting plate 22, the fourth mounting plate 23 and the fifth mounting plate 24 are arranged in sequence along the height of the vapor kettle body 01. The fifth mounting plate 24 is arranged at the lowermost. The third mounting plate 22 and the fourth mounting plate 23 are arranged in interval, and a liquid inlet chamber 14 is formed between the third mounting plate 22 and the fourth mounting plate 23. The cooling liquid entering through the liquid inlet pipe 12 will first enter the liquid inlet chamber 14, and then enter the second heat exchange pipe 03 from the first liquid inlet 3 through the liquid inlet chamber 14. In this embodiment, the second heat exchange pipe 03 is arranged in a hollow structure, and the upper end of the second heat exchange pipe 03 is provided with an opening, and the lower end is in a blocked state.

[0044] In the embodiment, the first liquid inlet 3 is arranged above the second liquid inlet 31, when the first liquid inlet 3 is between the third mounting plate 22 and the fourth mounting plate 23, the second liquid inlet 31 is blocked by the fifth mounting plate 24, at this time, the liquid in the liquid chamber 14 will flow into the second heat exchange pipe 03 from the first liquid outlet pipe 11, because the second liquid inlet 31 is blocked by the fifth mounting plate 24, the cooling liquid in the second heat exchange pipe 03 cannot flow out from the second liquid inlet 31, the liquid in the second heat exchange pipe 03 can only flow upwards, and then flow out from the opening at the upper end of the second heat exchange pipe 03, and finally flow out from the second liquid outlet pipe 13 between the first mounting plate 2 and the second mounting plate 21.

[0045] The upper end of the first heat exchange pipe 02 is arranged as an opening, and the lower end is also arranged as an opening structure, the fifth mounting plate 24 is provided with a mounting bracket 32, the mounting bracket 32 is slidably connected to the fifth mounting plate 24, and the mounting bracket 32 is fixed to the second heat exchange pipe 03, the upper end of the mounting bracket 32 is fixedly installed with a limiting ring, the limiting ring abuts against the upper surface of the fifth mounting plate 24, so that the mounting bracket 32 and the second heat exchange pipe 03 can only move upwards. In the embodiment, during the sliding of the mounting bracket 32 on the fifth mounting plate 24, the cooling liquid above the fifth mounting plate 24 will not flow downward, at this time, the vapor kettle body 01 can be discharged through the flow guide pipe.

[0046] When the first heat exchange pipe 02 is blocked by solid sulfur, at this time, the corresponding second heat exchange pipe 03 corresponding to the corresponding first heat exchange pipe 02 is pushed upwards, and the mounting bracket 32 is moved upwards during the upward movement, and then the first liquid inlet 3 is moved upwards between the third mounting plate 22 and the fourth mounting plate 23, and finally the third mounting plate 22 blocks the first liquid inlet 3, the second liquid inlet 31 moves between the fourth mounting plate 23 and the fifth mounting plate 24, and the cooling liquid between the third mounting plate 22 and the fourth mounting plate 23 can enter the second heat exchange pipe 03 which does not move upwards, and cannot enter the second heat exchange pipe 03 which moves upwards, at this time, the cooling liquid with high temperature between the first mounting plate 2 and the second mounting plate 21 can flow downwards through the opening of the second heat exchange pipe 03 which moves upwards, because the cooling liquid flowing from the upper end has high temperature, at this time, the cooling liquid with high temperature can heat the first heat exchange pipe 02 which is blocked, so that the solid sulfur in the first heat exchange pipe 02 is melted, and the purpose of cleaning the first heat exchange pipe 02 which is blocked is achieved. After the first heat exchange pipe 02 which is blocked is cleaned, the second heat exchange pipe 03 is pushed downwards, so that the second heat exchange pipe 03 which moves downwards is reset, and finally the second heat exchange pipe 03 can continue to exchange heat with the sulfur vapor in the first heat exchange pipe 02, so that the entire vapor kettle body 01 does not need to be closed during the cleaning process, at this time, the production efficiency of sulfur can be improved.

[0047] The mounting frame 32 is provided with a blocking assembly 4, which can block the lower end opening of the first heat exchange pipe 02 when there is no liquid flowing down in the first heat exchange pipe 02. The blocking assembly 4 comprises a blocking plate 41 slidably connected to the mounting frame 32 and a blocking spring 42 fixed to the blocking plate 41. The end of the blocking spring 42 away from the mounting frame 32 is fixed to the mounting frame 32. The blocking spring 42 pushes the blocking plate 41 to block the opening of the first heat exchange pipe 02. After the sulfur vapor is liquefied, the sulfur liquid flowing downward will push the blocking plate 41 to move downward. At this time, the blocking spring 42 is compressed. During the downward movement of the blocking plate 41, the opening of the first heat exchange pipe 02 is opened. The sulfur liquid in the first heat exchange pipe 02 will flow into the lower part of the fifth mounting plate 24 through the lower end opening and then be discharged from the first liquid outlet pipe 11, thereby realizing the preparation of the sulfur liquid.

[0048] The mounting frame 32 is provided with a control assembly 5 for driving the second liquid outlet pipe 13 to move upward. The control assembly 5 comprises a control rod 51 slidably connected to the mounting frame 32 and a control spring 52 fixed to the control rod 51. The end of the control spring 52 away from the control rod 51 is fixed to the mounting frame 32. The control spring 52 pushes the control rod 51 to extend out of the mounting frame 32. In this embodiment, the control rod 51 slides along the axis direction of the second heat exchange pipe 03. The lower end surface of the blocking plate 41 is fixedly provided with a pressing rod 04 which is used to abut against the control rod 51.

[0049] In this embodiment, the upper surface of the control rod 51 is provided with an inclined surface 53 which gradually decreases in height near the edge of the second heat exchange pipe 03. When the liquid in the first heat exchange pipe 02 falls, it will push the blocking plate 41 to move downward. During the downward movement, the pressing rod 04 will abut against the inclined surface 53. When the liquid flow rate in the first heat exchange pipe 02 is the same, the pressing rod 04 will abut against the same position of the inclined surface 53. At this time, the pressing rod 04 will be pushed to move towards the axis of the second heat exchange pipe 03. At this time, the end surface of the control rod 51 will not extend out of the mounting frame 32. When the first heat exchange pipe 02 is blocked, the liquid flow rate in the first heat exchange pipe 02 will decrease. At this time, the force pushing the pushing rod will decrease. The pushing rod will extend out of the mounting frame 32 under the action of the pushing spring. Then the control rod 51 extending out of the mounting frame 32 can be directly moved upward. The upward moving control rod 51 will push the mounting frame 32 and the second heat exchange pipe 03 mounted thereon to move upward, thereby adjusting the positions of the first liquid inlet 3 and the second liquid inlet 31 on the second heat exchange pipe 03.

[0050] When the first heat exchange pipe 02 is blocked, the flow rate in the first heat exchange pipe 02 slows down, at which time the force pushing the blocking plate 41 to move downward also becomes smaller, and the force of the downward pressing rod 04 on the blocking plate 41 pushing the control rod 51 also becomes smaller, at which time the control spring 52 pushes the control rod 51 to extend out of the side of the mounting frame 32, which can push multiple control rods 51 to move upward at the same time, and the control rod 51 drives the mounting frame 32 and the second heat exchange pipe 03 arranged on the mounting frame 32 to move upward, the first liquid inlet 3 on the second heat exchange pipe 03 is blocked by the third mounting plate 22, and the second liquid inlet 31 is no longer in contact with the fifth mounting plate 24, at which time the second liquid inlet 31 leaks out, and the cooling liquid with a higher temperature between the first mounting plate 2 and the second mounting plate 21 will flow downward from the upper end opening of the second heat exchange pipe 03, and since the cooling liquid flowing downward has a higher temperature, it can heat the blocked first heat exchange pipe 02, and in the process of heating, the solid sulfur can be melted into a liquid, thereby achieving the purpose of facilitating the cleaning of the first heat exchange pipe 02.

[0051] When the first heat exchange pipe 02 is cleaned, the liquid in the second heat exchange pipe 03 will reset under the action of gravity, at which time the first liquid inlet 3 will move between the third mounting plate 22 and the fourth mounting plate 23, and the second liquid inlet 31 is blocked by the fifth mounting plate 24, at which time the cooling liquid between the third mounting plate 22 and the fourth mounting plate 23 will enter the second heat exchange pipe 03 through the first liquid inlet 3, and the cooling liquid in the second heat exchange pipe 03 moves from bottom to top, thereby continuing to react with the sulfur vapor in the first heat exchange pipe 02.

[0052] The control assembly 5 is provided with multiple, and the downward pressing rod 04 is also provided with multiple, and the multiple downward pressing rods 04 and the multiple control assemblies 5 are one-to-one corresponding, since the first heat exchange pipe 02 and the second heat exchange pipe 03 in the vapor kettle body 01 are both provided with multiple, each second heat exchange pipe 03 is fixed with a mounting frame 32, and the control assembly 5 on each mounting frame 32 is provided with multiple, which makes it more convenient to push the second heat exchange pipe 03 to move upward.

[0053] The driving assembly 6 is arranged on the steam kettle body 01, and is used to push the control rod 51 upwards. In the process of the upward movement of the control rod 51, the mounting frame 32 is pushed upwards, so that the position of the second heat exchange pipe 03 on the mounting frame 32 can be adjusted. The driving assembly 6 comprises a driving ring 61 which is slidably connected in the steam kettle body 01, a driving rod 62 which is fixed on the driving ring 61, and a driving cylinder 63 which is fixed on the steam kettle body 01. The piston rod of the driving cylinder 63 is fixed on the driving ring 61. When the control rod 51 needs to be pushed upwards, the driving cylinder 63 drives the driving ring 61 to move upwards, and the driving ring 61 drives the driving rod 62 to move upwards. The end surface of the driving rod 62 abuts against the surface of the control rod 51 which extends from the mounting frame 32, so that the blocked first heat exchange pipe 02 and the corresponding second heat exchange pipe 03 can be driven to move upwards. The first liquid inlet 3 of the second heat exchange pipe 03 moves upwards, and then the third mounting plate 22 is blocked by the first liquid inlet 3. The cooling liquid between the third mounting plate 22 and the fourth mounting plate 23 cannot enter the second heat exchange pipe 03, and the second liquid inlet 31 is not blocked by the fifth mounting plate 24. The cooling liquid with a higher temperature between the first mounting plate 2 and the second mounting plate 21 enters the second heat exchange pipe 03 from the upper end opening of the second heat exchange pipe 03 which moves upwards, so as to flow from top to bottom in the second heat exchange pipe 03 which moves upwards. In the process of the downward movement of the cooling liquid, the blocked first heat exchange pipe 02 is heated, and finally the first heat exchange pipe 02 is cleaned.

[0054] The filter screen is arranged above the first mounting plate 2. The sulfur steam entering from the air inlet pipe 1 first passes through the filter screen, and then is filtered by the filter screen, so as to reduce the impurities entering the first heat exchange pipe 02.

[0055] The implementation principle of the sulfur steam condensing device in the embodiment of the present application is as follows. When the sulfur is produced, the sulfur steam is introduced from the air inlet pipe 1, and enters the first heat exchange pipe 02. At the same time, the cooling liquid is introduced from the liquid inlet pipe 12, and enters the second heat exchange pipe 03 from the first liquid inlet 3. The cooling liquid flows from bottom to top, and the sulfur steam flows from top to bottom. Then, the sulfur steam is condensed, and the condensed sulfur is discharged through the first liquid outlet pipe 11.

[0056] In use, when the temperature of the cooling liquid changes, the liquid sulfur will solidify on the inner wall of the first heat exchange pipe 02, the downward flow rate of the liquid sulfur in the first heat exchange pipe 02 will slow down, then the force pushing the blocking plate 41 to move downward will also decrease, the downward pressing rod 04 no longer abuts against the inclined surface 53, the control spring 52 pushes the control rod 51 to extend out of the mounting frame 32, then the driving cylinder 63 drives the driving ring 61 and the driving rod 62 to move upward, which pushes the control rod 51 to move upward, the control rod 51 drives the second heat exchange pipe 03 to move upward in the process of moving upward, then the first liquid inlet 3 is blocked by the third mounting plate 22, the second liquid inlet 31 is opened, the cooling liquid with a higher temperature at the first mounting plate 2 and the second mounting plate 21 flows downward, thereby heating the blocked first heat exchange pipe 02, so that the sulfur solidified on the inner wall of the first heat exchange pipe 02 melts into liquid and flows out, thereby achieving the purpose of facilitating the cleaning of the first heat exchange pipe 02.

[0057] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
