[0014] Furthermore, in each arc bend pipe group, the number of the arc bend pipes is 1 to 10, and the arc diameter of the arc bend pipe is 10 mm to 1000 mm.

[0015] Furthermore, the nozzle diameter is 1 mm to 10 mm, and the arc elbow diameter is 3 mm to 20 mm.

[0016] A method for using the micro / supergravity-microinterface jet-type self-rotating reaction device for enhancing the catalytic hydrogenation of heavy turpentine / resin oil as described above and a method for using the same include the following steps:

[0017] (1) The heat exchange fluid inlet and the heat exchange fluid outlet are connected to the device for providing cold fluid for heat exchange; the fluid conveyor is connected to each device for providing materials, and is used to convey the materials heavy turpentine / resin oil and hydrogen to the material inlet respectively, and enter the fluid center tube of the super / microgravity-micro interface reactor through the material inlet. The material flow rate of the material conveyed by the fluid conveyor is determined by the size of the β value, and the specific calculation formula is as follows:

[0018] Centrifugal acceleration is G = Rω 2 (1)

[0019] The acceleration due to gravity of the earth is g = 9.81 m / s 2 (2)

[0020] Hypergravity / microgravity factors

[0021] Where: G-centrifugal acceleration, m / s 2 ;

[0041] Example 1

[0042] Figure 1 The schematic diagram of the structure of a micro / supergravity-micro interface jet-type self-rotating reaction device for enhancing the catalytic hydrogenation of heavy turpentine / resin oil of the present invention is shown. The reaction device comprises:

[0043] Heat exchanger 1 has a material inlet 101 at its upper end and a material outlet 102 at its lower end. A heat exchange fluid inlet 103 and a heat exchange fluid outlet 104 are provided on the sidewall of heat exchanger 1. The reaction proceeds within heat exchanger 1, releasing heat. Cooling fluid enters and exits heat exchanger 1 to control the reaction temperature.

[0044] The super / microgravity-microinterface reactor is arranged in a heat exchanger 1. The super / microgravity-microinterface reactor includes a fluid center tube 2 and a fluid distributor 3. The fluid center tube 2 is a cylindrical tube with an upper end open. The upper end of the fluid center tube 2 is connected to the material inlet 101. At least one fluid distributor 3 is arranged axially of the fluid center tube 2. The fluid distributor 3 includes at least three arc bend groups. Each arc bend group includes at least one arc bend 301. The arc bends 301 are radially distributed. When the number of arc bends 301 in each arc bend group is ≥2, the arc of the arc bend 301 is ≥1. The diameter increases from the inside to the outside, so that when the material is ejected from the nozzle 302 of the arc-shaped curved pipe 301 of different lengths, the reaction materials in different areas can be stirred, making the reaction more complete; the outer end of the arc-shaped curved pipe 301 is provided with a nozzle 302, and the inner end of the arc-shaped curved pipe 301 is connected to the fluid center pipe 2; the various materials are mixed and reacted through the super / microgravity-micro interface reactor, that is, the various materials enter the fluid center pipe 2 to complete the primary mixing (during the mixing period, the materials also undergo a chemical reaction), and then are sprayed into the heat exchanger 1 through the fluid distributor 3 to achieve secondary mixing and reaction;

[0045] and a fluid conveyor 4, wherein the material inlet 101 is connected to the fluid conveyor 4 and is used to convey various materials into the super / microgravity-microinterface reactor.

[0046] refer to Figure 1 and Figure 3 , the heat exchanger 1 is a shell and tube heat exchanger or a jacketed heat exchanger.

[0047] refer to Figure 1 、 Figure 2 and Figure 4 , 2 to 40 fluid distributors 3 are arranged axially in the fluid center tube 2, and the interval between each fluid distributor 3 is 50 mm to 800 mm. The number of fluid distributors 3 depends on the size of the heat exchanger 1. The larger the heat exchanger 1 is, the more fluid distributors 3 there are. The more fluid distributors 3 there are, the more uniform the mixing is and the more sufficient the stirring is.

[0048] refer to Figure 1 and Figure 3 The heat exchanger 1 has a diameter of 100 mm to 2000 mm and a height of 500 mm to 4000 mm.

[0049] refer to Figure 2 In each arc bend pipe group, the number of the arc bend pipes 301 is 1 to 10, and the arc diameter of the arc bend pipe 301 is 10 mm to 1000 mm;.

[0050] Continue to refer Figure 2 The diameter of the nozzle 302 is 1 mm to 10 mm, and the diameter of the arc elbow 301 is 3 mm to 20 mm.

[0051] Example 2

[0052] The method for using the micro / supergravity-micro interface jet-type self-rotating reaction device for enhancing the catalytic hydrogenation of heavy turpentine oil / resin oil in Example 1 is as follows:

[0053] (1) The heat exchange fluid inlet 103 and the heat exchange fluid outlet 104 are connected to the device for providing cold fluid for heat exchange. The heat exchanger 1 has a diameter of 100 mm and a height of 500 mm. The heavy turpentine / resin oil and hydrogen are respectively transported to the material inlet 101 at a certain speed through the fluid conveyor 4, and enter the fluid center tube 2 through the material inlet 101. There are 3 arc bend groups in each heat exchanger 1, and each arc bend group has two arc bends 301. The arc diameter of the first arc bend is 40 mm, and the arc diameter of the second arc bend is 70 mm. The diameter of the nozzle 302 is 1 mm, and the diameter of the arc bend 301 is 3 mm. There are 3 fluid distributors 3. Among them, the material flow rate V of the material transported by the fluid conveyor 4 is determined by the size of the β value, and the material flow rate is controlled to be 1.02 m / s. The specific calculation formula is as follows:

[0054] Centrifugal acceleration is G = Rω 2 (1)

[0055] The acceleration due to gravity of the earth is g = 9.81 m / s 2 (2)

[0056] Hypergravity / microgravity factors

[0057] Where: G—centrifugal acceleration, m / s 2 ; R—circular motion radius, m; g—earth gravity acceleration, m / s 2 ;ω—angular velocity of circular motion, 1 / s;β—super / microgravity factor;N—rotational speed of circular motion, r / min;π—pi;V—linear velocity of circular motion, m / s;

[0058] Specifically, each material is in a slightly heavy state after entering the fluid center tube 2, and β≥3. At this time, G≥29.43m / s 2 Because there are two arc elbows 301, each with a different arc radius, in order to ensure that the β value meets the above requirements, the arc radius of the largest arc elbow is used to calculate V, that is, R = 0.035m, then V = 1.02m / s; because the arc radius of the arc elbows is different in the super / microgravity-microinterface reactor, the material will be stirred at different positions in the heat exchanger 1 when it is ejected, which increases the uniformity of material mixing, makes the reaction more complete, and reduces the installation of stirring equipment;

[0059] (2) Material A (i.e., heavy turpentine / resin oil) and material B (i.e., hydrogen) flowing in from the material inlet 101 are mixed once in the fluid center tube 2. Since the lower end of the fluid center tube 2 is closed, the material can only enter the arc bend tube 301 from the fluid center tube 2 and be ejected through the nozzle 302. Due to the speed imparted by the fluid conveyor 4, the ejected material generates centrifugal force, overcomes gravity to form a microgravity-microinterface field, thereby achieving the transmission process of the enhanced reaction system, and fully mixing reaction is carried out in this process. After the reaction is completed, the resulting reactants are discharged from the material outlet 102; during the reaction, cold fluid enters from the heat exchange fluid inlet 103, completes heat exchange with the reaction raw materials, and then flows out through the heat exchange fluid outlet 104.

[0060] Example 3

[0061] The method for using the micro / supergravity-micro interface jet-type self-rotating reaction device for enhancing the catalytic hydrogenation of heavy turpentine oil / resin oil in Example 1 is as follows:

[0062] (1) The heat exchange fluid inlet 103 and the heat exchange fluid outlet 104 are connected to the device for providing cold fluid for heat exchange. The heat exchanger 1 has a diameter of 2000 mm and a height of 4000 mm. The heavy turpentine / resin oil and hydrogen are respectively transported to the material inlet 101 at a certain speed through the fluid conveyor 4, and enter the fluid center pipe 2 through the material inlet 101. There are 4 arc bend groups in each heat exchanger 1, and each arc bend group has five arc bends 301. The arc diameter of the first arc bend is 20 0mm, the arc diameter of the second arc elbow is 400mm, the arc diameter of the third arc elbow is 800mm, the arc diameter of the fourth arc elbow is 1000mm, the arc diameter of the fifth arc elbow is 1500mm, the diameter of the nozzle 302 is 10mm, the diameter of the arc elbow 301 is 20mm, and there are 15 fluid distributors 3; among them, the material flow rate V conveyed by the fluid conveyor 4 is determined by the size of the β value, and the material flow rate is controlled to be 22.76m / s. The specific calculation formula is as follows:

[0063] Centrifugal acceleration is G = Rω 2 (1)

[0064] The acceleration due to gravity of the earth is g = 9.81 m / s 2 (2)

[0065] Hypergravity / microgravity factors

[0066] Where: G-centrifugal acceleration, m / s 2 ; R-circular motion radius, m; g-earth gravity acceleration, m / s 2;ω-angular velocity of circular motion, 1 / s;β-super / microgravity factor;N-rotational speed of circular motion, R / min;π-circular ratio;V-linear velocity of circular motion, m / s;

[0067] Specifically, after each material enters the fluid center tube 2, it is in an overweight state, and β≥70. At this time, G≥294.3m / s 2 Because there are five arc bends 301, each with a different arc radius, in order to ensure that the β value meets the above requirements, the arc radius of the largest arc bend is used to calculate V, that is, R = 0.75m, then V = 22.76m / s; because the arc radius of the arc bends in the super / microgravity-microinterface reactor is different, the material will be stirred at different positions in the heat exchanger 1 when it is ejected, which increases the uniformity of material mixing, makes the reaction more complete, and reduces the installation of stirring equipment;

[0068] (2) Material A (i.e., heavy turpentine / resin oil) and material B (i.e., hydrogen) flowing in from the material inlet 101 are mixed once in the fluid center tube 2. Since the lower end of the fluid center tube 2 is closed, the material can only enter the arc bend tube 301 from the fluid center tube 2 and be ejected through the nozzle 302. Due to the speed imparted by the fluid conveyor 4, the ejected material generates centrifugal force, overcomes gravity to form a supergravity-microinterface field, thereby achieving the transmission process of the enhanced reaction system, and fully mixes and reacts in this process. After the reaction is completed, the resulting reactants are discharged from the material outlet 102; during the reaction, a cold fluid enters from the heat exchange fluid inlet 103, completes heat exchange with the reaction raw materials, and then flows out through the heat exchange fluid outlet 104.

[0069] Example 4

[0070] The method for using the micro / supergravity-micro interface jet-type self-rotating reaction device for enhancing the catalytic hydrogenation of heavy turpentine oil / resin oil in Example 1 is as follows:

[0071] (1) The heat exchange fluid inlet 103 and the heat exchange fluid outlet 104 are connected to the device for providing cold fluid for heat exchange. The heat exchanger 1 has a diameter of 1000 mm and a height of 3000 mm. The materials heavy turpentine / resin oil and hydrogen are respectively transported to the material inlet 101 at a certain speed through the fluid conveyor 4, and enter the fluid center tube 2 through the material inlet 101. There are 4 arc bend groups in each heat exchanger 1, and each arc bend group has four arc bends 301. The first arc bend The arc diameter of the arc bend is 100 mm, the arc diameter of the second arc bend is 300 mm, the arc diameter of the third arc bend is 500 mm, and the arc diameter of the fourth arc bend is 800 mm. The diameter of the nozzle 302 is 7 mm, the diameter of the arc bend 301 is 20 mm, and there are 6 fluid distributors 3. The material flow rate V of the material transported by the fluid conveyor 4 is determined by the size of the β value, and the material flow rate is controlled to be 12.57 m / s. The specific calculation formula is as follows:

[0072] Centrifugal acceleration is G = Rω 2 (1)

[0073] The acceleration due to gravity of the earth is g = 9.81 m / s 2 (2)

[0074] Hypergravity / microgravity factors

[0075] Where: G-centrifugal acceleration, m / s 2 ; R-circular motion radius, m; g-earth gravity acceleration, m / s 2 ;ω-angular velocity of circular motion, 1 / s;β-super / microgravity factor;N-rotational speed of circular motion, R / min;π-circular ratio;V-linear velocity of circular motion, m / s;

[0076] Specifically, after each material enters the fluid center tube 2, it is in a super / micro-gravity state, and β≥40. At this time, G≥392.4m / s 2 Because there are four arc bends 301, each with a different arc radius, in order to ensure that the β value meets the above requirements, the arc radius of the largest arc bend is used to calculate V, that is, R = 0.4m, then V = 12.57m / s; because the arc radius of the arc bends in the super / microgravity-microinterface reactor is different, the material will be stirred at different positions in the heat exchanger 1 when it is ejected, which increases the uniformity of material mixing, makes the reaction more complete, and reduces the installation of stirring equipment;

[0077] (2) Material A (i.e., heavy turpentine / resin oil) and material B (i.e., hydrogen) flowing in from the material inlet 101 are mixed once in the fluid center tube 2. Since the lower end of the fluid center tube 2 is closed, the material can only enter the arc bend tube 301 from the fluid center tube 2 and be ejected through the nozzle 302. Due to the speed imparted by the fluid conveyor 4, the ejected material generates centrifugal force, overcomes gravity to form a super / microgravity-micro interface field, thereby achieving the transmission process of the enhanced reaction system, and fully mixing reaction is carried out in this process. After the reaction is completed, the resulting reactants are discharged from the material outlet 102; during the reaction, cold fluid enters from the heat exchange fluid inlet 103, completes heat exchange with the reaction raw materials, and then flows out through the heat exchange fluid outlet 104.

[0079] The method for using the micro / supergravity-micro interface jet-type self-rotating reaction device for enhancing the catalytic hydrogenation of heavy turpentine oil / resin oil in Example 1 is as follows:

[0080] (1) The heat exchange fluid inlet 103 and the heat exchange fluid outlet 104 are connected to the device for providing cold fluid for heat exchange. The heat exchanger 1 has a diameter of 300 mm and a height of 1000 mm. The heavy turpentine / resin oil and hydrogen are respectively transported to the material inlet 101 at a certain speed through the fluid conveyor 4, and enter the fluid center tube 2 through the material inlet 101. There are 3 arc bend groups in each heat exchanger 1, and each arc bend group has three arc bends 301. The arc diameter of the first arc bend is 80 mm, the arc diameter of the second arc bend is 120 mm, and the arc diameter of the third arc bend is 220 mm. The diameter of the nozzle 302 is 3 mm, and the diameter of the arc bend 301 is 12 mm. There are 4 fluid distributors 3. Among them, the material flow rate V of the material transported by the fluid conveyor 4 is determined by the size of the β value, and the material flow rate is controlled to be 4.66 m / s. The specific calculation formula is as follows:

[0081] Centrifugal acceleration is G = Rω 2 (1)

[0082] The acceleration due to gravity of the earth is g = 9.81 m / s 2 (2)

[0083] Hypergravity / microgravity factors

[0084] Where: G-centrifugal acceleration, m / s 2 ; R-circular motion radius, m; g-earth gravity acceleration, m / s 2;ω-angular velocity of circular motion, 1 / s;β-super / microgravity factor;N-rotational speed of circular motion, R / min;π-circular ratio;V-linear velocity of circular motion, m / s;

[0085] Specifically, after each material enters the fluid center tube 2, it is in a super / micro-gravity state, and β≥20. At this time, G≥196.2m / s 2 Because there are three arc bends 301, each with a different arc radius, in order to ensure that the β value meets the above requirements, the arc radius of the largest arc bend is used to calculate V, that is, R = 0.11m, then V = 4.66m / s; because the arc radius of the arc bends in the super / microgravity-microinterface reactor is different, the material will be stirred at different positions in the heat exchanger 1 when it is ejected, which increases the uniformity of material mixing, makes the reaction more complete, and reduces the installation of stirring equipment;

[0086] (2) Material A (i.e., heavy turpentine / resin oil) and material B (i.e., hydrogen) flowing in from the material inlet 101 are mixed once in the fluid center tube 2. Since the lower end of the fluid center tube 2 is closed, the material can only enter the arc bend tube 301 from the fluid center tube 2 and be ejected through the nozzle 302. Due to the speed imparted by the fluid conveyor 4, the ejected material generates centrifugal force, overcomes gravity to form a super / microgravity-micro interface field, thereby achieving the transmission process of the enhanced reaction system, and fully mixing reaction is carried out in this process. After the reaction is completed, the resulting reactants are discharged from the material outlet 102; during the reaction, cold fluid enters from the heat exchange fluid inlet 103, completes heat exchange with the reaction raw materials, and then flows out through the heat exchange fluid outlet 104.
