Description

Technical Field

[0001] The present application relates to the technical field of chemical synthesis, and in particular to a pipeline reactor and a reaction system. Background Art

[0002] A pipeline reactor is a continuously operated reactor that is tubular and has a large aspect ratio. The reactor structure can be a single tube or multiple tubes in parallel.

[0003] During use of the pipeline reactor of the related art, a screw propeller is required to push the solid materials in the pipeline reactor forward, which consumes a lot of energy and has high operating costs. Summary of the Invention

[0004] In view of the above problems, the present application provides a pipeline reactor and a reaction system, which can solve the problem of high energy consumption during the use of the pipeline reactor.

[0005] To solve the above technical problems, in a first aspect, the present application proposes a pipeline reactor, comprising:

[0006] A tube body, wherein one end of the tube body along the axial direction is provided with a first inlet for the entry of gaseous materials, and a side wall of the tube body is provided with a second inlet for the entry of solid-phase materials;

[0007] A support seat is provided below the tube body, an end of the tube body facing the first inlet forms a preset angle with the support seat, and an end of the tube body away from the first inlet abuts against the support seat.

[0008] In the technical solution of the embodiment of the present application, gas is delivered into the tube from the first inlet, and solid-phase material is delivered into the tube from the second inlet. At this time, the gas and solid-phase material react within the tube. Because the end of the tube facing the first inlet is at a predetermined angle to the support seat, when the solid-phase material is delivered into the tube from the second inlet, it flows along the inner wall of the tube under the action of its own gravity.

[0009] Since the first inlet is located at one end of the tube body in the axial direction and the second inlet is located on the side wall of the tube body, when the gas and solid-phase material enter the tube body from the first inlet and the second inlet respectively, the gas can further serve as a power source to push the solid-phase material to flow in the tube body. At this time, the solid-phase material can flow to the other end of the tube body under the dual action of its own gravity and the gas as a power source. The overall process does not require any other power source to meet the movement of the solid-phase material in the tube body, effectively reducing energy consumption costs.

[0010] In some embodiments, the first inlet is coaxially disposed with the tube body, and the second inlet is disposed radially along the sidewall of the tube body. Thus, the gas entering the tube body through the first inlet is completely blown onto the solid-phase material entering the tube body through the second inlet, thereby ensuring sufficient reaction between the gas and the solid-phase material and preventing the gas entering the tube body through the first inlet from blowing the solid-phase material onto the inner wall of the tube body.

[0011] In some embodiments, the invention further comprises a distribution assembly disposed within the tube body for uniformly distributing the gaseous material delivered from the first inlet into the tube body radially within the tube body; the distance between the distribution assembly and the first inlet is smaller than the distance between the second inlet and the first inlet. Thus, when the gas enters the tube body from the first inlet, the gas is evenly distributed radially within the tube body, thereby ensuring more complete contact between the gas and the solid-phase material and improving reaction efficiency.

[0012] In some embodiments, a purge assembly is further included, wherein the purge assembly is disposed on the inner wall of the tube body facing the support seat, and the second inlet is disposed on the side wall of the tube body facing away from the support seat;

[0013] The distance between the purge assembly and the first inlet is greater than the distance between the second inlet and the first inlet. The arrangement of the purge assembly can prevent solid phase materials entering the tube body from the second inlet from being deposited on the inner wall of the tube body.

[0014] In some embodiments, the air outlet of the purge assembly faces the side of the tube body facing the support seat. In this way, when the solid-phase material enters the tube body through the second inlet and is deposited on the inner wall of the tube body facing the support seat under the action of its own gravity, the purge assembly can blow up the deposited solid-phase material, so that the solid-phase material is in a fluidized state and effectively reacts with the gas.

[0015] In some embodiments, a heating component is further included, and the heating component is arranged on the tube body. The arrangement of the heating component facilitates heating the tube body.

[0016] In some embodiments, the heating assembly includes a sleeve and a heat-conducting material, the tube is sleeved within the sleeve, and the heat-conducting material is disposed between the tube and the sleeve. In this way, by replacing different heat-conducting materials, the heating temperature of the tube can be easily controlled.

[0017] In some embodiments, the support base includes a base plate, a telescopic rod, and a clamp; one end of the telescopic rod is connected to the clamp, and the other end is connected to the base plate; the end of the tube facing the first inlet is disposed on the clamp, and the end of the tube away from the first inlet abuts the base plate. In this way, the angle between the tube and the base plate can be easily adjusted by adjusting the length of the telescopic rod.

[0018] In some embodiments, the inner wall of the tube is smooth, which can reduce the adsorption and accumulation of solid phase materials on the inner wall of the tube.

[0019] In a second aspect, the present application proposes a reaction system, comprising a pipeline reactor as described in any one of the embodiments of the present application.

In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification.

[0033] Below, this application is described in detail.

[0034] A pipeline reactor is a continuously operated reactor that is tubular and has a large aspect ratio. This type of reactor can be very long, such as the reactor tube for propylene dimerization, which is measured in kilometers; shorter ones, such as the pipeline reactor in fine chemicals, are generally tens of meters long.

[0035] Most of the current pipeline reactors are equipped with a screw propeller. When solid material enters the pipeline reactor from one side, the screw propeller is started to push the solid material forward. At the same time, gas enters the pipeline reactor from the other side and reacts with the solid material.

[0036] It has been found that the existing pipeline reactor requires power equipment to drive the screw propeller to rotate, which consumes a lot of energy and has high operating costs.

[0037] In order to solve the above technical problems, Figure 1 As shown, an embodiment of the present application provides a pipeline reactor, including a tube body 10 and a support seat 14, wherein a first inlet 101 for entry of gaseous materials is provided at one axial end of the tube body 10, and a second inlet 102 for entry of solid-phase materials is provided on the side wall of the tube body 10; the support seat 14 is arranged below the tube body 10, and an end of the tube body 10 facing the first inlet 101 forms a preset angle with the support seat 14, and an end of the tube body 10 away from the first inlet 101 abuts against the support seat 14.

[0038] In this embodiment, the first inlet 101 and the second inlet 102 are both connected to the inner cavity of the tube body 10. Figure 1 As shown, the first inlet 101 is located at the left end of the tube body 10, and the second inlet 102 is located at the upper end of the side wall of the tube body 10. When the gas enters the tube body from the first inlet 101 and the solid phase material enters the tube body from the second inlet 102, the gas will react with the solid phase material when it flows from the left end to the right end in the tube body.

[0039] In this embodiment, the support seat 14 is located below the tube body, and the angle between the left end of the tube body 10 and the support seat is α, where 0°<α≤90°. For example, α can be 15°, 45°, etc., and can be determined according to actual conditions. This specification does not limit this.

[0040] The right end of the tube body 10 can be connected to the right end of the support base 14 via a ball joint mechanism. In this case, the tube body 10 can rotate relative to the support base 14, and the right end of the tube body 10 can also abut against a limit plate (not shown in the figure) on the right end of the support base 14. It should be noted that this application does not impose any particular restrictions on the specific structure of the right end of the tube body 10 and the right end of the support base 14, as long as the above structure can achieve the purpose of this application.

[0041] This technical solution delivers gas into the tube body 10 through the first inlet 101 and solid-phase material into the tube body 10 through the second inlet 102. At this time, the gas and solid-phase material react within the tube body 10. Because the end of the tube body 10 facing the first inlet 101 is at a predetermined angle to the support base 14, when the solid-phase material is delivered into the tube body 10 through the second inlet 102, it flows along the inner wall of the tube body 10 from the left end to the right end under the action of its own gravity.

[0042] Since the first inlet 101 is located at the left end of the tube body 10 in the axial direction, and the second inlet 102 is located on the side wall of the tube body 10, when the gas and solid-phase material enter the tube body 10 from the first inlet 101 and the second inlet 102 respectively, the gas can further serve as a power source to push the solid-phase material to flow in the tube body 10. At this time, the solid-phase material can flow to the other end of the tube body 10 under the dual action of its own gravity and the gas as a power source. The overall process can meet the movement of the solid-phase material in the tube body 10 without the need for other power sources, effectively reducing energy consumption costs.

[0043] According to some embodiments of the present application, reference Figure 1 As shown, the first inlet 101 is coaxially arranged with the tube body 10 , and the second inlet 102 is arranged on the side wall of the tube body 10 along the radial direction of the tube body 10 .

[0044] In this embodiment, the axial direction of the first inlet 101 and the axial direction of the second inlet 102 are perpendicular to each other. Of course, it is understandable that the first inlet 101 can be set at an angle with the axial direction of the tube body 10, for example, the angle between the axial direction of the first inlet 101 and the axial direction of the tube body 10 is 5° or 10°; the second inlet 102 can be set at an angle with the radial direction of the tube body 10, for example, the angle between the axial direction of the second inlet 102 and the radial direction of the tube body 10 is 3° or 6°, etc. The specific angles can be determined according to actual conditions and are not limited in this embodiment of the present invention.

[0045] Since the first inlet 101 is coaxially arranged with the tube body 10, the gas entering the tube body 10 from the first inlet 101 will all be blown onto the solid-phase material entering the tube body 10 from the second inlet 102, so as to ensure that the gas and the solid-phase material fully react and prevent the gas entering the tube body 10 from the first inlet 101 from blowing the solid-phase material onto the inner wall of the tube body 10.

[0046] According to some embodiments of the present application, the pipeline reactor also includes an equal distribution component 11, which is arranged in the pipe body 10 and is used to evenly distribute the gaseous material transported from the first inlet 101 into the pipe body 10 radially into the pipe body 10; the distance from the equal distribution component 11 to the first inlet 101 is less than the distance from the second inlet 102 to the first inlet 101.

[0047] In this embodiment, the equalizing component 11 may be a gas equalizer, etc., which may be determined according to actual conditions and is not limited in this embodiment of the present specification.

[0048] When in use, after the gas enters the tube body 10 from the first inlet 101, the gas blown into the tube body 10 can be evenly distributed radially into the tube body 10 through the function of the averaging component 11. At the same time, since the distance from the averaging component 11 to the first inlet 101 is smaller than the distance from the second inlet 102 to the first inlet 101, the reference Figure 1 As shown, when the solid-phase material enters the tube body 10 from the second inlet 102, the gas processed by the equalizing component 11 will be evenly blown onto the corresponding solid-phase material to avoid uneven distribution of the gas blown onto the solid-phase material. This allows the gas to contact the solid-phase material more fully, thereby improving the reaction efficiency.

[0049] According to some embodiments of the present application, the pipeline reactor also includes a purge assembly 12, which is arranged on the inner wall of the tube body 10 facing the support seat 14, and the second inlet 102 is arranged on the side wall of the tube body 10 facing away from the support seat 14; the distance from the purge assembly 12 to the first inlet 101 is greater than the distance from the second inlet 102 to the first inlet 101.

[0050] In this embodiment, the purge component 12 may be a gas phase pulse purge device or a fan, etc., which may be determined according to actual conditions and is not limited in this embodiment of the present specification.

[0051] like Figure 1As shown, since the purge component 12 is arranged on the inner wall of the tube body 10 facing the support seat 14, the second inlet 102 is arranged on the side wall of the tube body 10 away from the support seat 14, that is, the purge component 12 and the second inlet 102 are located on opposite sides of the tube body 10 in the radial direction. In this way, when the solid-phase material enters the tube body 10 from the second inlet 102, the solid-phase material falls onto the inner wall of the tube body 10 along the gravity direction of the solid-phase material under the action of its own gravity. Since the distance from the purge component 12 to the first inlet 101 is greater than the distance from the second inlet 102 to the first inlet 101, at this time, the purge component 12 can blow up the solid-phase material that falls onto the inner wall of the tube body 10 along the gravity direction of the solid-phase material, thereby preventing the solid-phase material that enters the tube body 10 from the second inlet 102 from being deposited on the inner wall of the tube body 10.

[0052] According to some embodiments of the present application, the air outlet of the purge assembly 12 faces the side of the tube body 10 facing the support base 14. In this way, when the solid-phase material enters the tube body 10 from the second inlet 102 and is deposited on the inner wall of the tube body 10 facing the support base 14 under the action of its own gravity, the purge assembly 12 can blow up the deposited solid-phase material, so that the solid-phase material is in a fluidized state and effectively reacts with the gas.

[0053] According to some embodiments of the present application, the pipeline reactor further includes a heating assembly 13 , which is disposed on the pipe body 10 .

[0054] In this embodiment, the heating assembly 13 may include a sleeve and a heat-conducting material, wherein the tube 10 is sleeved within the sleeve, and the heat-conducting material is disposed between the tube 10 and the sleeve. The heat-conducting material may be oil, water, or the like, and may be determined based on actual conditions and is not limited in this embodiment.

[0055] During use, when the sleeve is heated, due to the different thermal conductivity coefficients of different heat-conducting materials, by replacing different heat-conducting materials, the temperature transferred to the tube body 10 will be different, thereby making it convenient to control the heating temperature of the tube body 10.

[0056] It should be noted that the above-described heating assembly structure is merely an example. In other alternative solutions, other structures may also be adopted. For example, the heating assembly may include a heating wire wound around the side wall of the tube. This application does not impose any particular restrictions on the specific structure of the heating assembly, as long as the above-described structure can achieve the objectives of this application.

[0057] According to some embodiments of the present application, Figure 1As shown, the support base 14 includes a base plate 141, a telescopic rod 142 and a clamp 143, wherein one end of the telescopic rod 142 is connected to the clamp 143, and the other end is connected to the base plate 141, and the end of the tube body 10 facing the first inlet 101 is set on the clamp 143, and the end of the tube body 10 away from the first inlet 101 is in contact with the base plate 141.

[0058] In this embodiment, the telescopic rod 142 may be an electric telescopic rod or a telescopic sleeve rod, which may be determined according to actual conditions and is not limited in this embodiment of the present specification.

[0059] When using, such as Figure 1 As shown, the left end of the tube body 10 is clamped on the clamp 143 , and the right end of the tube body 10 can be connected to the right end of the base plate 141 through a ball link mechanism. At this time, the tube body 10 can rotate relative to the base plate 141 .

[0060] During use, the angle α between the tube body 10 and the bottom plate 141 can be conveniently adjusted by adjusting the length of the telescopic rod 142 .

[0061] It should be noted that the above-mentioned support base structure is only an example. In other alternative solutions, other structures can also be adopted, for example, the support base as a whole is a pad with a right-angled triangle structure. This application does not impose any special restrictions on the specific structure of the support base, as long as the above-mentioned structure can achieve the purpose of this application.

[0062] According to some embodiments of the present application, the inner wall of the tube body 10 is a smooth structure. For example, a smooth layer can be provided inside the tube body 10. This can reduce the adsorption and accumulation of solid-phase materials on the inner wall of the tube body 10 after solid-phase materials enter the tube body 10.

[0063] The present application also provides a reaction system including a pipeline reactor as described in any one of the embodiments of the present application. The pipeline reactor in the present application can refer to the above embodiments. Since the reaction system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be detailed here.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
