Description

Technical Field

[0001] This invention belongs to the technical field of stainless steel reaction vessels, specifically, it relates to a chemical steam-heated stainless steel reaction vessel. Background Technology

[0002] Stainless steel reactors are currently used in the chemical, food, coating, hot melt adhesive, silicone, paint, pharmaceutical, and petrochemical industries to handle the reaction, evaporation, synthesis, polymerization, saponification, sulfonation, chlorination, and nitration of compounds in production. The stainless steel reactor mainly consists of four major components: inner tank, jacket, agitator, and support base.

[0003] During the use of stainless steel reactors, a heating medium is needed to control the internal temperature of the reactor. In one type of stainless steel reactor in the existing technology, steam is used to heat the inside of the reactor. The steam flows from bottom to top in the jacket, gradually raising the temperature inside the reactor and causing the chemical materials inside the reactor to react.

[0004] In existing technologies, during the upward flow of steam from the jacket, when the steam comes into contact with the pipes inside the jacket and the temperature of the pipes inside the jacket is low, steam condensation is easily caused, and the condensate flows downward. When this happens, because the temperature of the pipes inside the jacket is low, a large amount of steam is needed to raise the temperature inside the jacket before the steam can flow upward and raise the temperature inside the reactor. This process consumes a lot of steam and is not conducive to quickly getting the reactor into working condition. Summary of the Invention

[0005] The purpose of this invention is to provide a chemical steam-heated stainless steel reactor, which solves the technical problem in the related art that the large temperature difference between the reactor and the steam during the initial operation of the reactor leads to low efficiency of the steam in the initial heating of the reactor.

A permeable separation bar is provided inside the spiral conveying pipeline. The permeable separation bar divides the spiral conveying pipeline into a steam flow channel and a cooling water flow channel. Steam and cooling water flow in the steam flow channel and the cooling water flow channel, respectively. Both the steam flow channel and the cooling water flow channel are in contact with the inner arc surface of the jacket. After the steam condenses, the liquid flows downward into the cooling water flow channel through the permeable separation bar. A hot gas injection assembly is connected to the cooling water flow channel, which has multiple hot gas discharge ports. The hot gas injection assembly blows condensate downwards in the cooling water flow channel and maintains the temperature inside the steam flow channel.

[0007] According to an exemplary embodiment of this disclosure, the hot gas injection assembly includes a gas injection tube and an integrated pipeline. The number of gas injection tubes is set to multiple, and all of the multiple gas injection tubes pass through the jacket and are connected to the cooling water flow channel. A hot gas discharge port is provided on one side of the gas injection tube, and the integrated pipeline is connected between one end of the multiple gas injection tubes for centralized delivery of hot gas into the multiple gas injection tubes.

[0008] According to an exemplary embodiment of this disclosure, a bottom mounting ring is provided on the inner bottom wall of the jacket, the bottom of the spiral conveying pipeline passes through the bottom mounting ring, a partition ring plate is fixedly connected to the middle of the inner side of the bottom mounting ring, a collection chamber and a partition chamber are formed on the upper and lower sides of the partition ring plate respectively, condensate and cooling water flow into the collection chamber through the cooling water flow channel, and a drain valve pipe is connected to one side of the collection chamber.

[0009] According to an exemplary embodiment of this disclosure, a steam conveying device is provided on one side of the reactor body, and a steam inlet pipe is connected to the bottom of the steam flow channel. The steam inlet pipe passes through the collection chamber and the partition chamber, and one end of the steam inlet pipe is connected to the steam conveying device.

[0010] According to an exemplary embodiment of this disclosure, the condensate collected in the collection chamber is heated by the hot air, so that the steam flowing into the pipe remains in a vaporized state.

[0011] According to an exemplary embodiment of this disclosure, a heat exchange chamber is provided on one side of the top of the reactor body. A partition vertical plate is provided inside the heat exchange chamber, which divides the heat exchange chamber into a steam discharge chamber and a cooling water injection chamber. An exhaust valve pipe is provided at the top of the steam discharge chamber, and a water injection valve pipe is connected to the top of the cooling water injection chamber.

[0012] According to an exemplary embodiment of this disclosure, both the top of the steam flow channel and the cooling water flow channel are connected to inlet and outlet pipes, and the two inlet and outlet pipes respectively discharge steam or input cooling water.

[0013] According to an exemplary embodiment of this disclosure, a plurality of triangular guide grooves are longitudinally fixedly connected to the top of the steam discharge chamber. An inclined flow channel is provided inside the triangular guide grooves. A plurality of through grooves are provided on both sides of the triangular guide grooves. Steam condenses between the plurality of triangular guide grooves and collects the condensate through the inclined flow channel.

[0014] According to an exemplary embodiment of this disclosure, a water injection tank and a water supply tank are respectively provided on the upper and lower sides of the cooling water injection chamber. The bottom side of the water supply tank is connected to one of the inlet and outlet pipes. A sloping flow channel is provided inside the water supply tank. Multiple vertical channels are connected to the bottom of the water injection tank.

[0015] According to an exemplary embodiment of this disclosure, the dividing vertical plate has multiple water inlets corresponding to the multiple inclined flow channels, wherein a condensate flow area is formed between two corresponding vertical channels, so that condensate is injected into the water supply tank.

[0016] The present invention provides a chemical steam-heated stainless steel reactor. By using a hot gas injection component, steam can condense in the steam flow channel and permeate into the cooling water flow channel, thereby accelerating the downward flow of condensate in the cooling water flow channel. Furthermore, during the flow of hot gas in the cooling water flow channel, the internal temperature of the spiral conveying pipeline can be increased as quickly as possible, allowing the spiral conveying pipeline to preheat quickly, accelerating the temperature rise inside the reactor body, reducing steam condensation, and speeding up the commissioning of the reactor body.

[0017] This invention provides a chemical steam-heated stainless steel reactor. By installing a bottom-mounted ring cylinder at the bottom of the jacket, the condensate and cooling water after being heated by hot gas are temporarily stored. This allows the collection chamber to serve as the intermediate area between the steam and the spiral conveying pipeline, reducing the temperature difference between the steam and the not-yet-fully-preheated spiral conveying pipeline. This prevents the steam from condensing before entering the spiral conveying pipeline and increases the gradual conveying distance of the steam within the spiral conveying pipeline.

[0018] The present invention provides a chemical steam-heated stainless steel reactor. When the reactor body is heated to a sufficient temperature and cooling water is needed to condense the interior of the reactor body, a heat exchange box is provided. The steam discharged from the spiral conveying pipeline exchanges heat with the cooling water in the heat exchange box to form condensate. The condensate is then discharged into the cooling water flow channel in the spiral conveying pipeline, utilizing the remaining steam and preventing the steam from condensing and stagnating in the steam flow channel.

[0029] like Figures 1 to 8 As shown, a chemical steam-heated stainless steel reactor according to an embodiment of the present invention is illustrated, including a reactor body 1, a jacket 2 provided between the inner and outer walls of the reactor body 1, and a stirrer 3 provided inside the reactor body 1. The reactor body 1 is a common pressure vessel made of stainless steel in the prior art, and is often used in the chemical field to carry out reaction operations on various chemical materials. The stirrer 3 is generally provided inside the reactor body 1 to fully mix various chemical materials during the reaction.

[0030] refer to Figure 3 and Figure 6In one possible implementation, a spiral conveying pipeline 4 is also included. The spiral conveying pipeline 4 is disposed within the jacket 2 and can convey steam from bottom to top and cooling water from top to bottom. A permeable separating bar 5 is installed within the spiral conveying pipeline 4, dividing it into a steam flow channel 6 and a cooling water flow channel 7. Steam and cooling water flow through the steam flow channel 6 and cooling water flow channel 7 respectively, and both the steam flow channel 6 and cooling water flow channel 7 are in contact with the inner arc surface of the jacket 2. After the steam condenses, the liquid passes through the permeable separating bar 5 and enters the cooling water flow channel. The steam flows downward in the channel 7. When it is necessary to raise the internal temperature of the reactor body 1, the steam is transported upward through the steam flow channel 6 to heat the inside of the reactor body 1. Due to the temperature difference between the steam and the reactor body 1, some steam will condense. The condensate will remain in the permeation separation bar 5. The permeation separation bar 5 can support liquid infiltration. Since the shape of the permeation separation bar 5 is the same as that of the spiral conveying pipe 4, the liquid can slowly flow downward on the upper surface of the permeation separation bar 5, allowing the condensate to seep into the cooling water flow channel 7. After the chemical reaction is completed in the reactor body 1, when it is necessary to cool down the inside of the reactor body 1, cooling water is transported downwards in the jacket 2 through the cooling water flow channel 7 to cool down the inside of the reactor body 1.

[0031] As a specific embodiment, refer to Figure 5 A hot air injection component with multiple hot air discharge ports 8 is connected to the cooling water flow channel 7. This component blows condensate downwards within the cooling water flow channel 7 and maintains the temperature inside the steam flow channel 6. The hot air injection component includes injection tubes 9 and an integrated pipeline 10. Multiple injection tubes 9 are provided, and all of them pass through the jacket 2 and are connected to the cooling water flow channel 7. A hot air discharge port 8 is provided on one side of each injection tube 9. An integrated pipeline 10 is connected between one end of each injection tube 9 to centrally deliver hot air into the injection tubes 9. An external hot air source is connected to the integrated pipeline 10, and the hot air is first delivered to the integrated pipeline 10. Then, the hot air enters the injection tubes 9 separately and is finally discharged into the cooling water flow channel 7 through the multiple hot air discharge ports 8. Using hot air can accelerate the flow of condensate into the collection chamber 13 and can also quickly raise the temperature inside the spiral conveying pipeline 4, reducing the generation of condensate in the steam flow channel 6.

[0032] A bottom mounting ring 11 is provided on the inner bottom wall of the jacket 2, for reference. Figure 3The bottom of the spiral conveying pipeline 4 passes through a bottom-mounted ring cylinder 11. A partition ring plate 12 is fixedly connected to the middle of the inner side of the bottom-mounted ring cylinder 11. The upper and lower sides of the partition ring plate 12 form a collection chamber 13 and a partition chamber 14, respectively. Condensate and cooling water flow into the collection chamber 13 through the cooling water flow channel 7. A drain valve pipe 15 is connected to one side of the collection chamber 13. The heated condensate flows into the collection chamber 13 through the cooling water flow channel 7. The collection chamber 13 can also pre-store some warm water to prevent the cooling water from becoming too hot. After being heated by combining with hot air, the steam is stored in the collection chamber 13. This not only preheats the spiral conveying pipeline 4 and the interior of the reactor body 1, but also allows the collection chamber 13 to serve as the intermediate area between the spiral conveying pipeline 4 and the steam, reducing the temperature difference between the steam and the not-yet-fully-preheated spiral conveying pipeline 4. This prevents the steam from condensing before entering the spiral conveying pipeline 4. Meanwhile, the isolation chamber 14 is used to allow the steam to enter the pipeline 17 to extend fully, preventing the temperature difference from affecting the steam's movement out of the steam conveying equipment 16.

[0033] A steam conveying device 16 is provided on one side of the reactor body 1. The bottom of the steam flow channel 6 is connected to a steam inlet pipe 17. The steam inlet pipe 17 passes through the collection chamber 13 and the isolation chamber 14. One end of the steam inlet pipe 17 is connected to the steam conveying device 16. The steam conveying device 16 is a prior art device that produces and conveys steam. The steam is conveyed through the steam inlet pipe 17 using the steam conveying device 16. The arrangement path of the steam inlet pipe 17 is arranged along the circumference of the bottom-mounted ring cylinder 11, so that the steam inlet pipe 17 is fully arranged between the collection chamber 13 and the isolation chamber 14. The condensate collected in the collection chamber 13 is heated by the hot air, so that the steam flowing in the steam inlet pipe 17 is kept in a vaporized state, which facilitates the temperature maintenance in the collection chamber 13 and the isolation chamber 14 during the steam flow process.

[0034] A heat exchange box 18 is provided on one side of the top of the reactor body 1, for reference. Figure 7The heat exchange chamber 18 is equipped with a partition vertical plate 19, which divides the heat exchange chamber 18 into a steam discharge chamber 20 and a cooling water injection chamber 21. An exhaust valve pipe 22 is installed at the top of the steam discharge chamber 20, and a water injection valve pipe 23 is connected to the top of the cooling water injection chamber 21. After excess steam is delivered to the steam discharge chamber 20, in order to utilize the moisture in the steam, the steam in the steam discharge chamber 20 can be cooled by the temperature difference between itself and the cooling water injection chamber 21. After use, the steam in the reactor body 1 is condensed into condensate and discharged into the cooling water injection chamber 21. The gas in the steam discharge chamber 20 can be discharged through the exhaust valve pipe 22. When it is necessary to inject cooling water into the spiral conveying pipeline 4, the external water source is connected to the water injection valve pipe 23, and water is injected into the cooling water injection chamber 21 through the water injection valve pipe 23, and then the cooling water enters the cooling water flow channel 7. The exhaust valve pipe 22 and the water injection valve pipe 23 are both equipped with corresponding valves.

[0035] Both the top of the steam flow channel 6 and the cooling water flow channel 7 are connected to inlet and outlet pipes 24. The two inlet and outlet pipes 24 respectively discharge steam or input cooling water. The top of both inlet and outlet pipes 24 are equipped with control valves to control the flow of steam or cooling water.

[0036] Multiple triangular guide grooves 25 are longitudinally fixedly connected to the top of the steam discharge chamber 20. An inclined flow channel 26 is provided inside the triangular guide groove 25. Multiple through grooves 27 are opened on both sides of the triangular guide groove 25. Steam condenses between the multiple triangular guide grooves 25 and collects the condensate through the inclined flow channel 26. After the steam is discharged into the steam discharge chamber 20, the steam flows upward in the multiple through grooves 27. After the steam comes into contact with the bottom of the triangular guide groove 25, the steam will condense at the bottom of the triangular guide groove 25. Then the condensate falls from the bottom of the triangular guide groove 25 into the inclined flow channel 26, and then the condensate enters the cooling water injection chamber 21 along the inclined flow channel 26.

[0037] Cooling water injection chamber 21 has a water injection tank 28 and a water supply tank 29 on its upper and lower sides, respectively. The bottom of the water supply tank 29 is connected to one of the inlet / outlet pipes 24. A sloping flow channel 30 is provided inside the water supply tank 29. Multiple vertical channels 31 are connected to the bottom of the water injection tank 28, through which cooling water is injected into the water supply tank 29. Cooling water is also injected into the water injection tank 28 via the water injection valve pipe 23. Cooling water flows downward through multiple vertical channels 31, injecting cooling water into the water supply tank 29. Then, the cooling water flows along the sloping flow channel 30 in the water supply tank 29 into the corresponding inlet and outlet pipes 24. After the control valve at the top of the inlet and outlet pipes 24 is closed, the cooling water can maintain a certain water level in the cooling water injection chamber 21 (the water level is located at the bottom of the lowest water outlet 32), thereby affecting the internal temperature of the steam discharge chamber 20 and causing excess steam to condense.

[0038] Multiple water inlets 32 are provided on the partition vertical plate 19 corresponding to multiple inclined flow channels 26. A condensate flow area 33 is formed between two corresponding vertical channels 31, so that condensate is injected into the water supply tank 29. The condensate flowing along the inclined flow channels 26 into the cooling water injection chamber 21 is allowed to enter the cooling water injection chamber 21 through the multiple water inlets 32. The condensate then flows downward along the partition vertical plate 19 from the condensate flow area 33 formed between the two corresponding vertical channels 31.

[0039] The working principle of this chemical steam-heated stainless steel reactor: When it is necessary to use the reactor body 1 to heat and react various chemical materials, firstly, while keeping hot air added to the cooling water flow channel 7, cooling water is injected into the cooling water flow channel 7. After the cooling water comes into contact with the hot air, it heats up and begins to preheat the spiral conveying pipeline 4 and the inside of the reactor body 1. After heating up, the cooling water accumulates in the collection chamber 13. At this time, steam is transported to the steam flow channel 6 through the steam inlet pipeline. The steam is used to heat the inside of the reactor body 1. The condensate generated by the steam condensation in the steam flow pipeline enters the cooling water flow channel 7 and also enters the collection chamber 13. When there is a lot of water retained in the collection chamber 13, it is discharged from the collection chamber 13 through the drain valve pipe 15. After the steam is discharged from the steam flow channel 6, in order to utilize the remaining moisture in the steam, the moisture in the steam is condensed and enters the cooling water injection chamber 21 by using the temperature difference between the steam discharge chamber 20 and the cooling water injection chamber 21 in the heat exchange box 18. After the reactor body 1 is used up, it is necessary to cool down the inside of the reactor body 1. Cooling water is injected into the cooling water flow channel 7 through the cooling water injection chamber 21. The cooling water flows spirally downward in the jacket 2 to fully cool down the reactor body 1. Finally, the cooling water enters the collection chamber 13 and is discharged through the drain valve pipe 15.
