Description

Technical Field

[0001] This invention relates to the field of compound production equipment technology, specifically to a multiphase synergistic hydrogenation and deoxygenation reaction apparatus and its reaction method. Background Technology

[0002] A hydrogenation reactor, also known as a reaction vessel, is a device used to prepare compounds. In preparing a compound, liquid raw materials and a catalyst are added to the reactor, the lid is closed, and nitrogen gas is introduced into the reactor. The sealing of the reactor is observed. After half an hour, hydrogen gas is introduced into the reactor multiple times to allow the hydrogen to react with the nitrogen gas inside. Then, hydrogen gas is continuously introduced, and the liquid raw materials, catalyst, and hydrogen react at high temperatures. After the reaction is complete, nitrogen gas is introduced into the reactor to react with the remaining hydrogen gas. After cooling, the compound is removed from the reactor and filtered to obtain the desired product.

[0003] During the operation of the device, high-pressure gas will be ejected from the middle and impact the fixed baffle, causing the liquid to be squeezed to both sides by the gas, which can easily cause wall flow and affect the uniformity of raw material distribution. Summary of the Invention

[0024] Preferably, the fixing assembly further includes an inlet and outlet opened on the side wall of the reaction vessel, a plurality of thermocouples are rotatably connected to the side wall of the reaction vessel and extend into the reaction vessel, and a cavity is formed between the fixing plate and the dispensing plate.

[0027] A reaction method for a multiphase synergistic hydrodeoxygenation reactor includes the following steps:

[0028] S1: Adding raw materials: First, add the high-pressure raw materials that have undergone some processing to the reaction vessel through the inlet distributor;

[0029] S2: Filtration distribution: Under the squeezing action of air pressure, the raw material will pass through the gap between the first and second rotating shafts and the second filter hole into the dirt collection basket, so that impurities can be filtered.

[0030] S3: Catalytic reaction: After being filtered through a fouling basket, the product is evenly distributed and gradually enters multiple catalyst layers to react. After the reaction is completed, it is discharged from the reactant outlet.

[0031] The present invention has the following beneficial effects:

[0032] (1) This invention addresses the problem that high-pressure gas ejected from the center collides with the fixed baffle and impacts upwards, causing liquid to be blown to both sides, easily resulting in wall flow and affecting the uniformity of raw material distribution. When the high-pressure gas-liquid mixture enters the inlet distributor, it collides with the second spiral fan blade, causing the second spiral fan blade to rotate on the inner wall of the chute, converting some of the kinetic energy of the high-pressure gas-liquid mixture, reducing the flow velocity of the raw material when ejected from the first spiral fan blade at the bottom of the inlet distributor, and preventing the raw material from impacting the surface of the fixed plate with a large kinetic energy. The fixed plate has a certain height around it. The protruding material continuously impacts the surface of the fixed disk, which may form more eddies. This can cause impurities to accumulate locally under the action of the eddies, resulting in blockages and uneven distribution of the material on the surface of the fixed disk. This affects the distribution effect of the distribution disk. At the same time, under the action of the spiral fan blades one and two inside the inlet distributor, the gas and liquid are centrifugally thrown into the reaction vessel from one of the spiral fan blades. This prevents the high-pressure gas from being ejected from the middle and impacting the fixed baffle, which would cause the liquid to be blown to both sides, easily causing wall flow and affecting the uniformity of the material distribution.

[0033] (2) This invention utilizes the characteristic of the above-mentioned raw material driving the rotation of the spiral fan blade II. When the raw material impacts the surface of the spiral fan blade II and drives the spiral fan blade II to rotate, the rotation of the spiral fan blade II will also cause the flow direction of the raw material to rotate and deviate. This will pre-swirl the raw material flowing inside the inlet distributor, thereby reducing the influence of the local eddy current generated by the collision on the liquid distribution in various directions when the raw material is thrown out. At the same time, the reduced flow velocity of the raw material will make the angle of the conical spray formed after the raw material is thrown out by the spiral fan blade I smaller, and the distance between the spray edge and the reactor wall will increase, thereby reducing the possibility of wall flow phenomenon to a certain extent.

[0034] (3) When wall flow occurs, the liquid flows along the inner wall of the reaction vessel into the cavity formed between the fixed plate and the distribution plate. When the liquid accumulates to a certain amount in the cavity, it will spread evenly through the filter hole. Under the action of air pressure, it enters the scale basket through the filter hole. Some impurities will be deposited at the bottom of the cavity. The raw materials sprayed onto the reactor wall are recovered and redistributed to avoid uneven distribution of raw materials caused by the sliding of raw materials along the inner wall due to wall flow.

[0035] (4) After the raw material is sprayed onto the surface of the fixed plate, the gas and liquid can pass through the gap between the first and second rotating shafts due to the pressure of the air. Under the squeezing action of the air pressure, the raw material will pass through the gap between the first and second rotating shafts and the filter hole 2 into the dirt collection basket, which can filter the impurities. At the same time, when the ejected raw material and gas impact the first and second rotating shafts, the impurities on the rotating shaft surface and in the gap will be washed because the first and second rotating shafts are tilted. Meanwhile, the first and second rotating shafts will rotate under the impact, making it less likely for impurities to get stuck in the gap, reducing the possibility of blockage, and extending the service life to a certain extent.

[0064] Protective mechanism 3 includes:

[0065] The protective component 31 is rotatably connected to the side wall of the fixed component 12 via a rotating member;

[0066] The rotating component includes a pivot 313 rotatably connected to the side wall of the sludge basket 125.

[0067] Example 2, please refer to Figure 4 - Figure 8 The present invention is a multiphase synergistic hydrogenation and deoxygenation reaction device. Based on the first embodiment, the reaction component 11 includes a catalyst support disk 113 fixedly connected to the inner wall of the reaction vessel 111. A plurality of catalyst discharge pipes 114 are provided on the side wall of the catalyst support disk 113. A cold hydrogen tank 115 is provided on the inner wall of the catalyst support disk 113. A cold hydrogen inlet 116 is provided on the side wall of the reaction vessel 111. The side wall of the cold hydrogen inlet 116 is connected to the side wall of the cold hydrogen tank 115.

[0068] The fixed assembly 12 includes a catalyst outlet pipe 122 opened on the side wall of the reaction vessel 111, and a reactant outlet 123 opened on the side wall of the reaction vessel 111.

[0069] The fixing assembly 12 also includes an inlet 124 opened on the side wall of the reaction vessel 111. Several thermocouples 126 are rotatably connected to the side wall of the reaction vessel 111 and extend into the reaction vessel 111. A cavity 222 is formed between the fixing plate 221 and the dispensing plate 112.

[0070] The deceleration assembly 21 includes a first spiral fan blade 212 fixedly connected to the inner wall of the inlet distributor 121, a groove 213 is provided on the inner wall of the inlet distributor 121, and a second spiral fan blade 214 is slidably connected to the inner wall of the groove 213.

[0071] The protective component 31 includes a second rotating shaft 314 opened on the side wall of the dirt collection basket 125. The side wall of the first rotating shaft 313 is slidably connected to the side wall of the second rotating shaft 314. A second filter hole 312 is opened on the side wall of the dirt collection basket 125, and a second cavity 311 is opened on the inner wall of the dirt collection basket 125.

[0072] First, the high-pressure raw material, which has undergone some processing steps, is added to the reaction vessel 111 through the inlet distributor 121. After being filtered through the scale basket 125, it is evenly distributed and gradually enters multiple catalyst layers to react. After the reaction is completed, it is discharged from the reactant outlet 123. When the high-pressure gas-liquid mixture flows into the inlet distributor 121, it collides with the second spiral fan blade 214, causing the spiral fan blade 214 to rotate on the inner wall of the chute 213. Through the rotation of the spiral fan blade 214 and the friction between the spiral fan blade 214 and the inner wall of the chute 213, some of the kinetic energy of the high-pressure gas-liquid mixture can be converted, reducing the flow velocity of the raw material when it is ejected from the first spiral fan blade 212 at the bottom of the inlet distributor 121, thus preventing the raw material from flowing out at a high speed. The kinetic energy impacts the surface of the fixed disk 221. The fixed disk 221 has a certain height protrusion around it. The continuous impact of the raw material on the surface of the fixed disk 221 may form more eddies on the surface of the fixed disk 221. This can cause impurities to accumulate locally under the action of the eddies, resulting in blockages and uneven distribution of the raw material on the surface of the fixed disk 221, which affects the distribution effect of the distribution disk. At the same time, under the action of the spiral fan blade 1 212 and spiral fan blade 214 inside the inlet distributor 121, the gas and liquid are centrifugally thrown into the reaction vessel 111 from the spiral fan blade 1 212. This prevents the high-pressure gas from being ejected from the middle and impacting the fixed baffle 211, which would cause the liquid to be blown to both sides, easily causing wall flow and affecting the uniformity of the raw material distribution.

[0073] When the raw material collides with the spiral fan blade 214, local eddies are generated, which leads to uneven distribution of liquid in all directions when the raw material is thrown out of the spiral fan blade 212. When the raw material impacts the surface of the spiral fan blade 214 and drives the spiral fan blade 214 to rotate, the rotation of the spiral fan blade 214 will also cause the flow direction of the raw material to be rotated and deflected. This will pre-swirl the raw material flowing inside the inlet distributor 121, which will reduce the impact of the local eddies generated by the collision on the liquid distribution in all directions when the raw material is thrown out. At the same time, the reduced flow velocity of the raw material will make the angle of the conical spray formed after the raw material is thrown out of the spiral fan blade 212 smaller, and the distance between the spray edge and the reactor wall will be larger, which will reduce the possibility of wall flow to a certain extent.

[0074] When wall flow occurs, the liquid flows along the inner wall of the reaction vessel 111 into the cavity 222 formed between the fixed plate 221 and the distribution plate 112. When the liquid accumulates to a certain amount in the cavity 222, it will evenly spread through the filter holes 223. Under the action of air pressure, it enters the scale basket 125 through the filter holes 223. Some impurities will be deposited at the bottom of the cavity 222. The raw materials sprayed onto the reactor wall are recovered and redistributed to avoid uneven distribution of raw materials caused by the sliding of raw materials along the inner wall due to wall flow.

[0075] After the raw material is sprayed onto the surface of the fixed disc 221, the gap between the first rotating shaft 313 and the second rotating shaft 314 allows gas and liquid to pass through. Under the squeezing action of air pressure, the raw material will pass through the gap between the first rotating shaft 313 and the second rotating shaft 314 and the filter hole 312 into the dirt collection basket 125, thus filtering impurities. At the same time, when the ejected raw material and gas impact the first rotating shaft 313 and the second rotating shaft 314, because the first rotating shaft 313 and the second rotating shaft 314 are tilted, the impurities on the rotating shaft surface and in the gap will be washed away. At the same time, the first rotating shaft 313 and the second rotating shaft 314 will rotate under the impact, making it less likely for impurities to get stuck in the gap, reducing the possibility of blockage, and extending the service life to a certain extent.

[0076] The reaction method of this multiphase synergistic hydrodeoxygenation reactor includes the following steps:

[0077] S1: Adding raw materials: First, the high-pressure raw materials that have undergone some processing are added to the reaction vessel 111 through the inlet distributor 121;

[0078] S2: Filtration distribution: Under the squeezing action of air pressure, the raw material will pass through the gap between the first rotating shaft 313 and the second rotating shaft 314 and the second filter hole 312 into the dirt collection basket 125, so that impurities can be filtered.

[0079] S3: Catalytic reaction: After being filtered through the scale basket 125, the product is evenly distributed and gradually enters multiple catalyst layers to react. After the reaction is completed, it is discharged from the reactant outlet 123.

[0080] A specific application of this embodiment is as follows: First, the high-pressure raw material, which has undergone some processing, is added to the reaction vessel 111 through the inlet distributor 121. After being filtered through the scale basket 125, it is evenly distributed and gradually enters multiple catalyst layers to react. After the reaction is completed, it is discharged from the reactant outlet 123. When the high-pressure gas-liquid mixture flows into the inlet distributor 121, it will collide with the second spiral fan blade 214, which will drive the second spiral fan blade 214 to rotate on the inner wall of the chute 213. Through the rotation of the second spiral fan blade 214 and the friction between the second spiral fan blade 214 and the inner wall of the chute 213, some of the kinetic energy of the high-pressure gas-liquid mixture can be converted, reducing the flow velocity of the raw material when it is ejected from the first spiral fan blade 212 at the bottom of the inlet distributor 121, thus avoiding... The raw materials impact the surface of the fixed disk 221 with a large kinetic energy. The fixed disk 221 has a certain height protrusion around it. The continuous impact of the raw materials on the surface of the fixed disk 221 may form more eddies on the surface of the fixed disk 221. This can cause impurities to accumulate locally under the action of the eddies, resulting in blockage and uneven distribution of the raw materials on the surface of the fixed disk 221, which affects the distribution effect of the distribution disk. At the same time, under the action of the spiral fan blades 212 and 214 inside the inlet distributor 121, the gas and liquid are centrifugally thrown into the reaction vessel 111 from the spiral fan blade 212. This prevents the high-pressure gas from being ejected from the middle and impacting the fixed baffle 211 and then impacting upwards, causing the liquid to be blown to both sides, which can easily cause wall flow and affect the uniformity of the raw material distribution.

[0081] When the raw material collides with the spiral fan blade 214, local eddies are generated, which leads to uneven distribution of liquid in all directions when the raw material is thrown out of the spiral fan blade 212. When the raw material impacts the surface of the spiral fan blade 214 and drives the spiral fan blade 214 to rotate, the rotation of the spiral fan blade 214 will also cause the flow direction of the raw material to be rotated and deflected. This will pre-swirl the raw material flowing inside the inlet distributor 121, which will reduce the impact of the local eddies generated by the collision on the liquid distribution in all directions when the raw material is thrown out. At the same time, the reduced flow velocity of the raw material will make the angle of the conical spray formed after the raw material is thrown out of the spiral fan blade 212 smaller, and the distance between the spray edge and the reactor wall will be larger, which will reduce the possibility of wall flow to a certain extent.

[0082] When wall flow occurs, the liquid flows along the inner wall of the reaction vessel 111 into the cavity 222 formed between the fixed plate 221 and the distribution plate 112. When the liquid accumulates to a certain amount in the cavity 222, it will evenly spread through the filter holes 223. Under the action of air pressure, it enters the scale basket 125 through the filter holes 223. Some impurities will be deposited at the bottom of the cavity 222. The raw materials sprayed onto the reactor wall are recovered and redistributed to avoid uneven distribution of raw materials caused by the sliding of raw materials along the inner wall due to wall flow.

[0083] After the raw material is sprayed onto the surface of the fixed disc 221, the gap between the rotating shaft 313 and the rotating shaft 314 allows gas and liquid to pass through. Under the pressure of the air, the raw material is forced through the gap between the rotating shaft 313 and the rotating shaft 314 and the filter hole 312 into the dirt collection basket 125. Then, it is filtered by ceramic balls, which can filter impurities multiple times. At the same time, when the ejected raw material and gas impact the rotating shaft 313 and the rotating shaft 314, because the rotating shaft 313 and the rotating shaft 314 are tilted, the impurities on the rotating shaft surface and in the gap will be washed away. At the same time, the rotating shaft 313 and the rotating shaft 314 will rotate under the impact, making it less likely for impurities to get stuck in the gap, reducing the possibility of blockage, and extending the service life to a certain extent.
