Description

Technical Field

[0001] This invention relates to the field of green ammonia preparation, specifically to a heat-conducting oil reaction apparatus for green ammonia preparation. Background Technology

[0002] Green ammonia typically refers to ammonia produced by using renewable energy to electrolyze water to produce hydrogen, and then synthesizing ammonia from hydrogen and nitrogen in the air under specific conditions. Its production process produces almost no carbon emissions and is an important component of the future clean energy system.

[0003] Currently, in the process of preparing green ammonia, in order to ensure that the ammonia synthesis reaction is carried out in a stable and controllable high-temperature environment, the existing technology usually uses heat transfer oil to heat the green ammonia synthesis equipment. Moreover, heat transfer oil has the characteristics of high boiling point and low vapor pressure. Therefore, high-temperature heat transfer can be achieved under almost atmospheric pressure conditions, avoiding the disadvantages of traditional steam heating which requires high-pressure equipment. Its stable thermal stability is suitable for the long-term high-temperature environment of green ammonia synthesis, ensuring uniform reaction temperature and improving synthesis efficiency.

[0004] However, as the usage time increases, the heat transfer oil that is repeatedly heated will produce a certain amount of oxidation products and deposits, which will increase the probability of blockage in the heating-related pipes and greatly shorten its own usage instructions. Although some auxiliary agents that can react with heat transfer oil to extend its service life, such as antioxidants and detergents, are disclosed in the existing technology, there is a lack of effective means of rapid diffusion and application. Secondly, there is a lack of technical means to remove the deposits in the heat transfer oil, and the reaction effect of the agents will still be greatly limited. Summary of the Invention

[0013] Preferably, a tapered rod aligned with one end of the output valve tube is fixedly nested inside the bottom inner side of the internally threaded sleeve.

During the spiral locking process between the internally threaded sleeve and the medicine bottle, the tapered rod can penetrate the sealing diaphragm. A clearance groove is provided on the surface of the tapered rod to allow the internal space of the medicine bottle to communicate with the internal space of the output valve tube. An electronic flow meter is provided at the other end of the output valve tube.

[0014] Preferably, the collecting component includes a transparent collecting box, and the top port of the transparent collecting box can be externally threaded to the port of the feed valve pipe away from the reactor.

[0032] The technical solution of the present invention will be clearly and completely described below with reference to preferred embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1-8 A heat transfer oil reaction device for preparing green ammonia includes a reaction vessel 1, a frame 4 installed at the bottom of the reaction vessel 1, and a heating component 13 fitted on the outside of the reaction vessel 1. The top and bottom of the reaction vessel 1 are respectively provided with an oil filling pipe 2 and an oil drain valve pipe 3. The inside of the reaction vessel 1 is fitted with a conical filter screen 5, a hollow drive shaft 6, and a composite output pipe 7. One end of the hollow drive shaft 6 passes through the inner side of the middle of the conical filter screen 5, and the composite output pipe 7 is installed on one end of the hollow drive shaft 6 and can reciprocate to clean the top surface of the conical filter screen 5 as the hollow drive shaft 6 rotates. The side wall of the reaction vessel 1 is fitted with a feed valve pipe 11 located at the top of the outer ring structure of the conical filter screen 5, and the other end of the feed valve pipe 11 extends to the outside of the reaction vessel 1 and is fitted with a collection component 12.

[0034] The top of the reactor 1 is equipped with a meshing transmission assembly 8 and a reagent output mechanism. The output structure of the meshing transmission assembly 8 is connected to the other end of the hollow transmission shaft 6 extending to the outer side of the top of the reactor 1. The reagent output mechanism includes a reagent output structure 9 and a transition conduit 10. One end of the transition conduit 10 is fitted inside the other end of the hollow transmission shaft 6, and the internal space of the hollow transmission shaft 6 is connected to the output structure of the reagent output structure 9. This allows the reagent output structure 9 to guide the reagent inside it into the reactor 1 through the flow channel space formed by the transition conduit 10, the hollow transmission shaft 6, and the composite output pipe 7. Bearings and sealing rings are nested at the fitting point between the other end of the hollow transmission shaft 6 and the top structure of the reactor 1, and at the fitting point between one end of the transition conduit 10 and the inner side of the other end of the hollow transmission shaft 6. This effectively improves the sealing effect of the connection between the hollow transmission shaft 6 and the reactor 1, and the sealing effect of the connection between the transition conduit 10 and the hollow transmission shaft 6.

[0035] The composite output pipe 7 includes a diversion pipe 71. One end of the diversion pipe 71 is fixedly fitted inside the hollow drive shaft 6 and communicates with the internal space of the hollow drive shaft 6. Several first branch pipes 72 and several second branch pipes 73 are arranged and installed at the top and bottom of the diversion pipe 71, respectively. Thus, multiple first branch pipes 72 and multiple second branch pipes 73 are linked with the diversion pipe 71 to provide multiple channels for the spread of the reagent inside the reactor 1, which meets the requirements for rapid mixing. Several second branch pipes 73 are made of rubber material to meet the requirements for flexible contact. The end of the diversion pipe 71 away from the hollow drive shaft 6 is set as a closed structure to ensure the diversion pressure of its own structure. The diversion pipe 71 is parallel to the surface of the top of the conical filter screen 5. The ends of several second branch pipes 73 away from the diversion pipe 71 can fit in contact with the surface of the top of the conical filter screen 5 to ensure the cleaning effect of the top surface of the conical filter screen 5 during subsequent extended use.

[0036] The meshing transmission assembly 8 includes a first gear 81, a second gear 82, and a brake servo motor 83. The first gear 81 and the second gear 82 are respectively mounted on the other end of the hollow transmission shaft 6 and connected to the output end of the brake servo motor 83, thereby meeting the subsequent automatic rotation operation requirements of the hollow transmission shaft 6 and optimizing the automation operation performance of the overall device. A first support frame is installed between the housing surface of the brake servo motor 83 and the top surface of the reactor 1 to ensure its stability during continuous operation. The reagent output structure 9 includes several internal threaded sleeves 91. An output valve pipe 92 is installed between the bottom of the internal threaded sleeve 91 and the top of the transition conduit 10. A reagent bottle 93 is installed inside the internal threaded sleeve 91. A second support frame is installed between the bottom surface of the internal threaded sleeve 91 and the top surface of the reactor 1 to ensure its stability during continuous operation.

[0037] The collecting component 12 includes a transparent collecting box 121, and the top port of the transparent collecting box 121 can be externally threaded to the port of the feed valve pipe 11 away from the reactor 1. The heating component 13 includes an electric heating plate and a heat insulation cover fitted outside the electric heating plate. The electric heating plate is attached to the surface of the reactor 1. The heat insulation cover is fitted outside the electric heating plate and fixed to the surface of the reactor 1. A slide rail 16 is fixed to the surface of the heat insulation cover. An annular plate 17 that can cover the collecting component 12 and the feed valve pipe 11 is snapped onto the outside of the slide rail 16. An annular baffle fixedly fitted outside the heat insulation cover is snapped onto the bottom of the annular plate 17.

[0038] During use, for heat transfer oil used in reciprocating heating, after a certain period of use, the valve inside the output valve pipe 92 can be opened, allowing the agent poured from the reagent bottle 93 into the internal threaded sleeve 91 to enter the interior of the transition conduit 10 through the output valve pipe 92. Then, the agent enters the heat transfer oil inside the reactor 1 through the guide channel formed by the transition conduit 10, the hollow drive shaft 6, and the composite output pipe 7. At the same time, the brake servo motor 83 is started, and the output end of the brake servo motor 83 drives the second gear 82 to mesh with the first gear 81, causing the first gear 81 to drive the hollow drive shaft 6 and the composite output pipe 7 to rotate automatically. This increases the centrifugal diffusion effect of the agent diffused inside the heat transfer oil, fully accelerates the mixing reaction rate of the agent and the heat transfer oil, maintains the chemical stability and cleanliness of the heat transfer oil, and reduces the probability of blockage in the subsequent related pipelines of the heat transfer oil.

[0039] For the deposits generated by the reciprocating heating of the heat transfer oil, the heat transfer oil will be filtered by the conical filter screen 5 during the circulation process inside the reactor 1. Under the guidance of the conical structure of the conical filter screen 5, the filtered deposits will flow to the top area of ​​the outer ring structure of the conical filter screen 5. When the hollow drive shaft 6 and the composite output pipe 7 rotate under the drive of the meshing drive assembly 8, the deposits flowing to the top area of ​​the outer ring structure of the conical filter screen 5 will enter the transparent collection box 121 in the collection component 12 through the open feed valve pipe 11 under the centrifugal action of the composite output pipe 7 for centralized collection. Subsequently, to check the collection status of the transparent collection box 121, the ring plate 17 can be pushed to make room for the collection component 12, and the amount of deposits collected inside the transparent collection box 121 can be directly observed. If the amount of deposits reaches the level that needs to be cleaned, the valve inside the feed valve pipe 11 is closed, the transparent collection box 121 is turned and separated from the feed valve pipe 11, and then a new and empty collection component 12 is installed.

[0040] like Figures 8-9A tapered rod 95, aligned with one end of the output valve pipe 92, is fixedly nested inside the bottom of the internally threaded sleeve 91. A sealing diaphragm 96 is fixed inside the bottom port of the medicine bottle 93. The inner wall of the internally threaded sleeve 91 and one end of the medicine bottle 93 can be threaded together. During the spiral locking process between the internally threaded sleeve 91 and the medicine bottle 93, the tapered rod 95 can penetrate the sealing diaphragm 96. A clearance groove is provided on the surface of the tapered rod 95 so that the internal space of the medicine bottle 93 communicates with the internal space of the output valve pipe 92. An electronic flow meter 94 is provided at the other end of the output valve pipe 92.

[0041] In use, considering the continuous and periodic delivery of the entire drug output structure 9, a sealed diaphragm 96 is used as a technical means to seal the internal space of the drug bottle 93. During the replacement and installation of the drug bottle 93 and the internal threaded sleeve 91, after the bottom port of the drug bottle 93 is connected to the internal thread of the internal threaded sleeve 91 to a certain depth to ensure a seal, the tapered rod 95 punctures the sealed diaphragm 96 during the further downward movement of the drug bottle 93, so that the drug bottle 93 and the output valve pipe 92 are connected, thereby providing a channel for subsequent drug delivery. Furthermore, during use, the electronic flow meter 94 can measure and record the amount of drug delivered in a single transaction, further optimizing the usage effect.

[0042] like Figure 10 An adjusting shaft 122 is fitted inside the top of the transparent collection box 121. One end of the adjusting shaft 122 is fitted to the corresponding side wall of the transparent collection box 121 through a bearing and a sealing ring and extends to the outside of the transparent collection box 121. Four filter screens 123 are arranged and installed on the surface of the other end of the adjusting shaft 122 along its circumference. Two filter screens 123 that are horizontally opposite can form a filter channel inside the transparent collection box 121. Four positioning cylinders 125 are arranged and installed on the surface of the transparent collection box 121 along the circumference of the adjusting shaft 122. A C-shaped clamping plate 124 is fixedly sleeved on the other end of the adjusting shaft 122. The two ends of the C-shaped clamping plate 124 can be engaged and limited with two opposite positioning cylinders 125.

[0043] In use, considering the possibility that the sediment collected inside the transparent collection box 121 may flow back into the reactor 1 along with the heat transfer oil inside the reactor 1, the four filter plates 123 are arranged in pairs to first filter and temporarily store the sediment collected inside the transparent collection box 121. Then, a time period is set. After the time is up, the ring plate 17 is pushed and the C-shaped clamping plate 124 is turned, so that the C-shaped clamping plate 124 drives the transparent collection box 121 and the four filter plates 123 to rotate 180 degrees. In this way, while maintaining the filtering and temporary storage effect inside the transparent collection box 121, the sediment inside the transparent collection box 121 is limited and blocked at the bottom of the transparent collection box 121 to prevent it from flowing further. Subsequently, the amount of sediment collected inside the transparent collection box 121 is directly observed. If it reaches the level that needs to be cleaned, the valve inside the feed valve pipe 11 is closed, the transparent collection box 121 is turned and separated from the feed valve pipe 11. Then, a new and empty collection component 12 is installed.

[0044] like Figures 1-3 The top of the reactor 1 is fitted with a reflux pipe 15 and a non-contact electronic thermometer 18, and the bottom of the reactor 1 is fixed with a transition pipe and connected to a pump assembly 14. The open port at the top of the oil filling pipe 2 is externally threaded with a sealing cap.

[0045] In use, the heat transfer oil inside the reactor 1 can be circulated and pumped by the pump assembly 14. The heat transfer oil heated to a certain temperature by the heating element 13 can be pumped to the designated coil for heat exchange processing of the green ammonia preparation device. After use, the heat transfer oil is returned to the inside of the reactor 1 through the return pipe 15 from the coil. In further use, the pump assembly 14 can be selected as a high-temperature resistant magnetic drive pump or a special circulation pump, and the non-contact electronic thermometer 18 can be an infrared electronic thermometer to measure the temperature of the heat transfer oil inside the reactor 1.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention. The invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
