Abstract

This invention relates to the field of alkane conversion equipment technology, and discloses an alkane conversion equipment for high-purity nitrogen hydrodeoxygenation, including a distribution mechanism installed on the inner wall of a tank, with a distribution disc fixedly connected to the inner wall of the tank; a separation mechanism installed on the inner wall of the distribution mechanism; and a flow guiding mechanism installed on the inner wall of the distribution mechanism.

This method prevents a large number of solid particles from entering the catalyst bed, thereby blocking the pores inside the catalyst and causing the gas to bypass the blocked catalyst area, forming a channel and reducing reaction efficiency.

Description

Technical Field

[0001] This invention relates to the field of alkane conversion equipment technology, specifically to an alkane conversion equipment for the hydrodeoxygenation of high-purity nitrogen. Background Technology

[0002] Pure nitrogen is a widely used protective gas and carrier gas in the electronics industry, chemical synthesis, metal heat treatment, food packaging and other fields. With the rapid development of technologies such as semiconductor manufacturing, photovoltaic industry, and high-end material preparation, the requirements for the impurity content in nitrogen are becoming increasingly stringent. Not only is the oxygen volume fraction required to be less than 1 ppm, but the total hydrocarbon (such as methane, ethane, etc.) volume fraction is also required to be less than 1 ppm, and impurities such as water and carbon dioxide must also be controlled at extremely low levels.

[0003] When the gas enters the device, it is not pure. It carries a lot of impurities. When the gas comes into contact with the catalyst bed, a lot of impurities will get stuck between the catalyst particles and form bridges. This reduces the contact area between the catalyst and the gas, and the gas bypasses the blocked area. Some of the catalyst is completely idle, reducing the catalytic conversion efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an alkane conversion device for the hydrodeoxygenation of high-purity nitrogen, comprising a tank, an inlet pipe fixedly connected to the top of the tank, an outlet pipe fixedly connected to the bottom of the tank, and further comprising:

[0005] The distribution mechanism is installed on the inner wall of the tank. A distribution plate is fixedly connected to the inner wall of the tank, and an expansion ring is fixedly connected to the top of the distribution plate.

[0006] The separation mechanism is installed on the inner wall of the distribution mechanism, and a top plate is fixedly connected to the inner wall of the expansion ring.

[0007] A flow guiding mechanism is installed on the inner wall of the distribution mechanism, and an arc-shaped ring is fixedly connected to the inner wall of the distribution plate.

[0008] The operator introduces gas through the inlet pipe, allowing the gas to come into contact with the separation mechanism. Guided by the flow guiding mechanism and the separation mechanism, the particles inside the gas fall into the distribution mechanism.

[0009] Preferably, the distribution mechanism includes:

[0010] The allocation component is located inside the expansion circle;

[0011] The flow diversion component is fixedly installed on the inner wall of the distribution component;

[0012] When the gas comes into contact with the distribution plate and the distribution components, the gas in a jet state is evenly distributed into the interior of each distribution component.

[0013] Preferably, the separation mechanism includes:

[0014] The connecting component is fixedly installed on the inner wall of the top plate;

[0015] A separation component is fixedly installed on the inner wall of the connecting component;

[0016] When the gas comes into contact with the separation component, the separation component changes the airflow direction and separates the solid particles in the gas.

[0017] Preferably, the flow guiding mechanism includes:

[0018] The guiding component is fixedly installed on the inner wall of the drainage component;

[0019] A flow guiding component is fixedly installed on the inner wall of the flow guiding component;

[0020] When the gas comes into contact with the flow guiding component, the flow guiding component will change the gas from its original jet state to a spiral diffusion state.

[0021] Preferably, the dispensing component includes a storage slot formed in the inner wall of the dispensing tray;

[0022] When the gas enters the separation mechanism, the solid particles are guided into the storage tank by the flow guiding mechanism and the separation mechanism.

[0023] Preferably, the drainage component includes a retaining ring fixedly connected to the inner wall of the storage tank;

[0024] When the gas passes through the separation mechanism, it first passes through the fixed ring and then enters the flow guiding component.

[0025] Preferably, the connecting assembly includes a plurality of connecting posts fixedly connected to the top plate on the side away from the intake pipe;

[0026] As the gas passes through the top plate, it comes into contact with the separation component, which causes the gas to move in the opposite direction, resulting in some solid particles being trapped on the separation component.

[0027] Preferably, the separation assembly includes an arc plate fixedly connected to one end of several connecting posts away from the top plate, a guide ring fixedly connected to the inner wall of the expansion ring, a blocking block slidably connected to the inner wall of the storage tank, and a locking block rotatably connected to the outer wall of the air intake pipe.

[0028] The arc plate consists of two opposing arc plates. When the gas comes into contact with the top arc plate, the gas is guided by the arc plate, causing the airflow to move in the opposite direction, leaving the particulate matter on the top arc plate. A torsion spring is installed at the junction of the locking block and the air inlet pipe. After the reaction is completed, the operator can remove the blockage block by rotating the locking block and clean the inside of the storage tank.

[0029] Preferably, the guiding component includes a shielding ring fixedly connected to one end of the fixed ring near the arc-shaped ring;

[0030] When solid particles on the arc-shaped ring are blown up by gas, they are blocked by the shielding ring and fall into the storage tank.

[0031] Preferably, the flow guiding component includes several connecting rods fixedly connected to the inner wall of the fixed ring, and a horn tube is fixedly connected to the end of the connecting rod away from the storage tank, and a threaded plate is fixedly connected to the inner wall of the horn tube.

[0032] When gas enters the inside of the horn tube, the gas is guided by the threaded plate, causing the gas near the inner wall of the horn tube to rotate and flow out.

[0033] The present invention has the following beneficial effects:

[0034] (1) By setting up an arc plate, when the gas enters the top plate and comes into contact with the arc plate, the gas will change its flow direction. The solid particles in the gas will be left in the arc plate above the arc plate due to the change in gas flow direction. The solid particles in the arc plate will leave the arc plate under the action of the subsequent gas. The solid particles will be guided to the arc ring through the guide ring. Then, they will enter the storage tank through the gas and the blocking ring. In this way, a large number of solid particles are prevented from entering the catalyst bed, thereby blocking the pores inside the catalyst. This will cause the gas to bypass the blocked catalyst area and form a channel, resulting in a decrease in reaction efficiency.

[0035] (2) By setting a threaded plate, when the gas flows out from the fixed ring, some of the gas will diffuse along the outer wall of the horn tube in a direction away from the horn tube, while the gas inside the horn tube will come into contact with the threaded plate. This will cause the gas close to the inner wall of the horn tube to start rotating, while the gas at the center of the horn tube is still in a jet state. In this way, the outer gas diffuses radially to the catalyst bed, so that the gas can be evenly distributed in the catalyst bed, making the gas intake of the catalyst bed more uniform and improving the utilization rate of the catalyst.

[0036] (3) By setting up an arc ring, the gas will change its flow direction once when it hits the arc plate. When the gas hits the top plate, it will change its flow direction again. Finally, when it passes through the arc ring, it will change its direction again. In this way, the initial kinetic energy of the gas is lost, the time the gas stays in the catalyst bed is extended, the reaction can be more complete, and the high-speed flowing gas is prevented from hitting the catalyst bed and causing a lot of wear to the catalyst bed.

[0037] (4) By setting up a storage tank, when solid particles flow into the storage tank along the channel between the arc ring and the shielding ring, some gas will enter the storage tank along with the solid particles. At this time, the gas inside the storage tank will start to move towards the edge of the storage tank and eventually flow out from the edge of the storage tank. In this way, some gas can flow out from the edge of the distribution plate, preventing the gas flow rate from approaching zero due to friction with the wall surface when it is close to the annular area of ​​the inner wall of the tank, resulting in the edge catalyst being idle and reducing the catalyst utilization rate.

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.

[0051] Example 1, please refer to Figures 1-8 This invention relates to an alkane conversion device for the hydrodeoxygenation of high-purity nitrogen, comprising a tank 14, an inlet pipe 12 fixedly connected to the top of the tank 14, an outlet pipe 13 fixedly connected to the bottom of the tank 14, and further comprising:

[0052] Distribution mechanism 2 is installed on the inner wall of tank 14. Distribution plate 211 is fixedly connected to the inner wall of tank 14. Expansion ring 221 is fixedly connected to the top of distribution plate 211.

[0053] Separation mechanism 3 is installed on the inner wall of distribution mechanism 2, and top plate 311 is fixedly connected to the inner wall of expansion ring 221.

[0054] The flow guiding mechanism 4 is installed on the inner wall of the distribution mechanism 2, and an arc ring 411 is fixedly connected to the inner wall of the distribution plate 211.

[0055] The operator introduces gas through the inlet pipe 12, allowing the gas to come into contact with the separation mechanism 3. Guided by the flow guiding mechanism 4 and the separation mechanism 3, the particles inside the gas fall into the distribution mechanism 2.

[0056] Distribution agency 2 includes:

[0057] Distribution component 21 is located inside expansion ring 221;

[0058] Drainage component 22 is fixedly disposed on the inner wall of distribution component 21;

[0059] When the gas comes into contact with the distribution disk 211 and the distribution component 21, the gas in the jet state is evenly distributed into the interior of each distribution component 21.

[0060] Example 2, please refer to Figures 2-9 This invention relates to an alkane conversion device in the hydrodeoxygenation of high-purity nitrogen. Based on Example 1, the separation mechanism 3 includes:

[0061] The connecting component 31 is fixedly installed on the inner wall of the top plate 311;

[0062] Separation component 32 is fixedly disposed on the inner wall of connection component 31;

[0063] When the gas comes into contact with the separation component 32, the separation component 32 changes the airflow direction and separates the solid particles in the gas.

[0064] The flow guiding mechanism 4 includes:

[0065] The guide component 41 is fixedly disposed on the inner wall of the drainage component 22;

[0066] The flow guiding component 42 is fixedly disposed on the inner wall of the flow guiding component 22;

[0067] When the gas comes into contact with the flow guiding component 42, the flow guiding component 42 will change the gas from the original jet state to the spiral diffusion state.

[0068] The dispensing component 21 includes a storage slot 212 formed on the inner wall of the dispensing tray 211;

[0069] When the gas enters the separation mechanism 3, the solid particles will enter the storage tank 212 through the guidance of the flow guiding mechanism 4 and the separation mechanism 3.

[0070] The drainage component 22 includes a retaining ring 222 that is fixedly connected to the inner wall of the storage tank 212;

[0071] When the gas passes through the separation mechanism 3, it first passes through the fixing ring 222 and then enters the flow guiding assembly 42. By setting up the storage tank 212, when solid particles flow into the storage tank 212 along the channel between the arc ring 411 and the shielding ring 412, some gas will follow the solid particles into the storage tank 212. At this time, the gas inside the storage tank 212 will start to move towards the edge of the storage tank 212 and eventually flow out from the edge of the storage tank 212. In this way, some gas can flow out from the edge of the distribution plate 211, preventing the gas flow rate from approaching zero due to friction with the wall in the annular area near the inner wall of the tank 14, which would cause the edge catalyst to be idle and reduce the catalyst utilization rate.

[0072] The connecting assembly 31 includes a plurality of connecting posts 312 fixedly connected to the top plate 311 on the side away from the intake pipe 12;

[0073] When the gas passes through the top plate 311, it comes into contact with the separation component 32, which causes the gas to move in the opposite direction, causing some solid particles to be retained on the separation component 32.

[0074] The separation assembly 32 includes an arc plate 321 fixedly connected to one end of a plurality of connecting posts 312 away from the top plate 311, a guide ring 322 fixedly connected to the inner wall of the expansion ring 221, a blocking block 323 slidably connected to the inner wall of the storage tank 212, and a locking block 324 rotatably connected to the outer wall of the air intake pipe 12.

[0075] The arc plate 321 consists of two opposing arc-shaped plates. When the gas contacts the top arc plate, it is guided by the arc plate 321, causing the airflow to reverse and leaving particles on the top arc plate 321. A torsion spring is installed at the junction of the locking block 324 and the inlet pipe 12. After the reaction, the operator rotates the locking block 324 to remove the blockage block 323 and clean the inside of the storage tank 212. By setting the arc plate 321, when the gas enters the top plate 311 and contacts the arc plate 321, the gas changes its flow direction, and the gas contains particles that are not properly disposed of in the arc plate. Due to the change in gas flow direction, the existing solid particles are retained in the arc plate above the arc plate 321. The solid particles in the arc plate 321 will leave the arc plate 321 under the action of the subsequent gas, and be guided to the arc ring 411 through the guide ring 322. Then, driven by the gas and blocked by the shielding ring 412, they enter the storage tank 212. In this way, a large number of solid particles are prevented from entering the catalyst bed and blocking the pores inside the catalyst. This causes the gas to bypass the blocked catalyst area and form a channel, resulting in a decrease in reaction efficiency.

[0076] The guide component 41 includes a shielding ring 412 that is fixedly connected to one end of the fixed ring 222 near the arc ring 411;

[0077] When solid particles on the arc ring 411 are blown up by the gas, they are blocked by the shielding ring 412 and fall into the storage tank 212. By setting the arc ring 411, the gas will change its flow direction once when it hits the arc plate 321. When the gas hits the top plate 311, it will change its flow direction again. Finally, when it passes through the arc ring 411, the gas direction will change again. In this way, the initial kinetic energy of the gas is lost, the time the gas stays in the catalyst bed is extended, the reaction can be more complete, and the high-speed flowing gas is prevented from hitting the catalyst bed and causing a lot of wear to the catalyst bed.

[0078] The flow guiding component 42 includes several connecting rods 421 fixedly connected to the inner wall of the fixing ring 222. The end of the connecting rod 421 away from the storage tank 212 is fixedly connected to a horn tube 422, and a threaded plate 423 is fixedly connected to the inner wall of the horn tube 422.

[0079] When gas enters the inside of the horn tube 422, it is guided by the threaded plate 423, causing the gas near the inner wall of the horn tube 422 to rotate and flow out. By setting the threaded plate 423, when the gas flows out from the fixed ring 222, some of the gas will diffuse along the outer wall of the horn tube 422 away from the horn tube 422, while the gas inside the horn tube 422 will come into contact with the threaded plate 423. This will cause the gas close to the inner wall of the horn tube 422 to start rotating, while the gas at the center of the horn tube 422 is still in a jet state. In this way, the outer gas diffuses radially to the catalyst bed, so that the gas can be evenly distributed in the catalyst bed, making the gas intake of the catalyst bed more uniform and improving the utilization rate of the catalyst.

[0080] A specific application of this embodiment is as follows: At the start of operation, the operator introduces raw material nitrogen into the tank 14 through the inlet pipe 12. When the gas passes through the inlet pipe 12, it first contacts the top plate 311 and the expansion ring 221. This causes some gas to enter the expansion ring 221 through the top plate 311, while the gas that does not enter the expansion ring 221 diffuses outward from one top plate 311, allowing the gas to enter another expansion ring 221. When the gas enters the top plate 311, it first contacts the arc plate 321. At this moment, the gas impacting the arc plate 321 changes direction and flows towards the inner wall of the top plate 311. The gas flowing along the top plate 311, along with the gas from the expansion ring 221, flows towards the arc ring 411. When the gas reaches the arc ring 411, it is guided again by the arc ring 411, causing the gas to move closer to the arc plate at the bottom of the arc plate 321. Simultaneously, the solid particles separated on the arc ring 411 are carried by the gas. As the solid particles are lifted into the air, they are blocked by the shielding ring 412. Particulate matter falls into the storage tank 212 through the channel between the arc ring 411 and the shielding ring 412. A small amount of gas also enters the storage tank 212 simultaneously. Meanwhile, the gas at the bottom of the arc plate 321 then enters the fixed ring 222. As the gas flows, it is separated again. Some gas flows along the outer wall of the horn tube 422, moving away from the horn tube 422. Meanwhile, the gas inside the horn tube 422... When the gas touches the threaded plate 423, the gas adhering to the inner wall of the horn tube 422 will rotate under the guidance of the threaded plate 423, while the gas at the center of the threaded plate 423 will still be in a jet state, causing the gas flowing out of the horn tube 422 to diffuse in a direction away from the horn tube 422. The gas inside the storage tank 212 will pass directly through the gaps on both sides of the storage tank 212 and the inlet pipe 12, and flow out from the edge of the distribution plate 211, and merge with the gas flowing out of the horn tube 422 to enter the catalyst bed.

[0081] After the reaction is complete, the operator rotates the locking block 324, at which point the torsion spring inside the locking block 324 begins to accumulate potential energy. At the same time, the operator pulls out the blocking block 323 and cleans the solid particles inside the storage tank 212.

[0082] By setting up the arc plate 321, when the gas enters the top plate 311 and comes into contact with the arc plate 321, the gas will change its flow direction. Due to the change in gas flow direction, the solid particles in the gas will be retained in the arc plate above the arc plate 321. The solid particles in the arc plate 321 will leave the arc plate 321 under the action of the subsequent gas, and will be guided to the arc ring 411 by the guide ring 322. Then, driven by the gas and blocked by the shielding ring 412, they will enter the storage tank 212. In this way, a large number of solid particles are prevented from entering the catalyst bed and blocking the pores inside the catalyst. This would cause the gas to bypass the blocked catalyst area and form a channel, resulting in a decrease in reaction efficiency.

[0083] By setting the arc ring 411, the gas will change its flow direction once when it hits the arc plate 321. When the gas hits the top plate 311, it will change its flow direction again. Finally, when it passes through the arc ring 411, the gas direction will change again. In this way, the initial kinetic energy of the gas is lost, the time the gas stays in the catalyst bed is extended, the reaction can be more complete, and the impact of high-speed flowing gas on the catalyst bed can be prevented, thus preventing a lot of wear on the catalyst bed.

[0084] By setting the threaded plate 423, when the gas flows out from the fixed ring 222, some of the gas will diffuse along the outer wall of the horn tube 422 in a direction away from the horn tube 422, while the gas inside the horn tube 422 will come into contact with the threaded plate 423. This will cause the gas close to the inner wall of the horn tube 422 to start rotating, while the gas at the center of the horn tube 422 is still in a jet state. In this way, the outer gas diffuses radially to the catalyst bed, so that the gas can be evenly distributed in the catalyst bed, making the gas intake of the catalyst bed more uniform and improving the utilization rate of the catalyst.

[0085] By setting up the storage tank 212, when solid particles flow into the storage tank 212 along the channel between the arc ring 411 and the shielding ring 412, some gas will follow the solid particles into the storage tank 212. At this time, the gas inside the storage tank 212 will start to move towards the edge of the storage tank 212 and eventually flow out from the edge of the storage tank 212. In this way, some gas can flow out from the edge of the distribution plate 211, preventing the gas flow rate from approaching zero due to friction with the wall in the annular area near the inner wall of the tank 14, which would cause the edge catalyst to be idle and reduce the catalyst utilization rate.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
