Description

[0002] The jacketed reactor is a commonly used chemical reaction equipment. It controls and adjusts the temperature of the reaction system by cooling or heating the medium in the jacket space, exchanging heat with the reactants in the reaction vessel, and has good heat control performance in various chemical reaction processes. Specifically, a jacket space is formed between the reaction vessel and the jacket of the jacketed reactor. The jacket space is filled with cooling or heating medium. The medium is sent into the jacket space from the outside through a circulating pump, circulated in the container, and exchanges heat with the reactants in the reaction vessel. When the reaction needs to be heated, the heat energy is transferred from the medium through the jacket to the reactant system, increasing its temperature. On the contrary, when the reaction needs to be cooled, the heat energy is transferred from the reactant system to the jacket medium, reducing its temperature.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with embodiments, but the protection scope of the present invention is not limited thereto.

[0022] Specific embodiment 1: A jacketed liner reactor based on supergravity.

[0023] like Figure 1 and Figure 2As shown, it includes a reactor body, a material circulation component 7 is arranged in the reactor body, and an ultra-gravity generating unit 5 is arranged outside the reactor body. The ultra-gravity generating unit 5 passes through the reactor body, and the output end of the ultra-gravity generating unit 5 extends into the material circulation component 7. The output end of the ultra-gravity generating unit 5 is provided with a rotor assembly 6 that cooperates with the material circulation component 7. The rotor assembly 6 includes a central material suction chamber 63 and a filling chamber 61 arranged around the material suction chamber 63. The material circulation component 7 is provided with a circulating material input port 79 and a circulating material output port 73. The material entering the material suction chamber 63 passes through the filling chamber 61 under the action of centrifugal force and enters the material circulation component 7. After entering the reactor body from the circulating material output port 73, it enters the material suction chamber 63 from the circulating material input port 79 for circulation.

[0024] In this specific embodiment, Figure 1 As shown, the reactor body is composed of a reaction liner 1, a dichloro jacket 2 and a steam jacket 3 which are sequentially arranged from the inside to the outside. The dichloro jacket 2 is heated by the steam in the steam jacket 3, and the reaction liner 1 is heated by the dichloro jacket 2, so as to better control the heating temperature. The material circulation component 7 is arranged at the bottom of the reaction liner 1, and an intermediate connector 4 is sealed at the bottom of the reaction liner 1. The intermediate connector 4 is fixedly connected to the dichloro jacket 2, which does not affect the steam passing into the steam jacket 3, and also does not affect the reaction in the reaction liner 1. The output end of the supergravity generating unit 5 passes through the intermediate connector 4 and is located in the material circulation component 7.

[0025] In this specific embodiment, the supergravity generating unit 5 refers to a device that simulates supergravity conditions by generating centrifugal force through rotation. Under the action of the supergravity generating unit 5, the material repeatedly enters the material circulation component 7, is dispersed, sheared and crushed by the filler in the filler cavity 61, and forms a constantly updated micro-element fluid, which accelerates the interface update, thereby realizing an efficient mass transfer and heat transfer process and chemical reaction process. The function of the rotor assembly 6 is to rotate under the action of the supergravity generating unit 5, generate a supergravity field, and shear and disperse the material.

[0026] like Figure 2 As shown, the material circulation component 7 includes a coaxially arranged inner guide tube 71, an outer guide tube 72 and a circulation cover plate 75 fixedly arranged between the inner guide tube 71 and the outer guide tube 72. The inner guide tube 71, the outer guide tube 72 and the circulation cover plate 75 form a circulation material chamber 78. The input end of the inner guide tube 71 is connected to the reaction liner 1, and the output end of the inner guide tube 71 is a circulation material input port 79. The circulation material output port 73 is arranged on the circulation cover plate 75, and the circulation material chamber 78 is connected to the reaction liner 1 through the circulation material output port 73.

[0027] like Figure 2As shown, a vortex-breaking baffle 74 is provided at the lower part of the inner guide tube 71, and the vortex-breaking baffle 74 extends into the material suction chamber 63. The purpose of setting the vortex-breaking baffle 74 is to destroy the stability of the liquid flow and generate vortices by increasing the Reynolds number, and to gradually eliminate the vortex by increasing the turbulent energy and dispersing the vortex energy, so as to achieve the effect of breaking the vortex. In the specific implementation process, a number of vortex-breaking baffles 74 are provided to destroy the vortex, which can avoid the erosion and corrosion of the high-speed swirl of the mixed material; in addition, since the inner side of the outer guide tube 72 and the reaction liner 1 will also form vortices, vortex-breaking baffles can also be provided on the inner side of the outer guide tube 72 and the reaction liner 1, and their functions are consistent with those of the vortex-breaking baffle 74 at the bottom of the inner guide tube 71.

[0028] like Figure 2 As shown, a filler is arranged in the filler cavity 61, and a rotor upper cover plate 62 is arranged at the upper end of the filler cavity 61, and the rotor upper cover plate 62 is opposite to the circulation cover plate 75, and at least one annular slider 64 is arranged on the rotor upper cover plate 62, and an annular chute 76 cooperating with the annular slider 64 is arranged on the circulation cover plate 75. Through the cooperation between the annular slider 64 and the annular chute 76, it is ensured that the rotor assembly 6 and the material circulation assembly 7 are always coaxial, and the working stability is ensured. In actual applications, the annular chute 76 can also be arranged on the rotor upper cover plate 62, and the annular slider 64 can be arranged on the circulation cover plate 75, and those skilled in the art can set it according to the needs.

[0029] like Figure 3 As shown, the intermediate connector 4 includes a sealingly connected mounting plate 45, an upper end plate 41 and a lower end plate 42. The mounting plate 45 is fixedly connected to the reaction liner 1 and sealed with a PTFE gasket; the circulating material assembly 7 is fixedly arranged on the mounting plate 45; the upper end plate 41 is fixedly connected to the dichloro jacket 2 and sealed with a PTFE gasket; a through hole 43 is coaxially arranged on the upper end plate 41 and the lower end plate 42, and the output end of the supergravity generating unit 5 passes through the lower end plate 42, the upper end plate 41 and the mounting plate 45 in sequence. A sealing layer (not shown in the figure) is provided between the upper end plate 41 and the lower end plate 42, including but not limited to an elastic rubber layer. The cavity of the intermediate connector 4 contains a packing sealing assembly and a cooling channel, which serves as a sealing assembly cavity of the output end of the supergravity generating unit 5, and plays the role of connection, sealing and cooling; this is a content that is easy to understand for those skilled in the art, and those skilled in the art can set it according to their needs.

[0030] In this specific embodiment, a limiting mechanism 44 is provided on the mounting plate 45, including but not limited to a bearing radially arranged on the mounting plate 45 and a thrust plate axially arranged. Its function is to ensure that when the supergravity generating unit 5 is installed in the through hole 43, its radial position and axial position reference remain unchanged, thereby increasing its and the rotor assembly 6's service life.

[0031] Considering the convenience of setting and the rationality of circulation, the inner guide tube 71 is coaxially provided with an original material input pipe 77 for initial feeding, and the output port of the original material input pipe 77 is located in the material suction chamber 63. The supergravity generating unit 5 is provided with a driving mechanism 8 and a circulating cooling pipe 81, and the circulating cooling pipe 81 is passed through dichloromethane for cooling, and in practical applications, the introduction and export of cooling water are also involved.

[0032] Specific embodiment 2: A reaction method using the jacketed liner reactor based on supergravity of specific embodiment 1.

[0033] The liquid mixed material in the reaction liner 1 is introduced into the material suction chamber 63 through the circulating material input port 79. Under the action of the centrifugal force of the supergravity generating unit 5, the liquid mixed material is sheared by the filler in the filler chamber 61 and enters the material circulation component 7. After being output from the circulating material output port 73, it enters the reaction liner 1 again and circulates continuously.

[0034] The above liquid phase mixed materials, including but not limited to anhydrous hydrogen fluoride, CH2Cl2, SbCl5, etc., are input into the material suction chamber 63 through the original material input pipe 77, and under the action of the centrifugal force of the supergravity generating unit 5, they are sheared by the filler in the filler chamber 61 and enter the circulating material chamber 78, and are output from the circulating material output port 73 and enter the reaction liner 1, and then are sucked into the material suction chamber 63 through the circulating material input port 79, and so on. Under the action of the filler, the circumferential speed increases, and the centrifugal force generated pushes it to the outer edge of the rotor assembly 6. In this process, the liquid is dispersed, sheared and broken by the filler to form a constantly updated extremely small micro-element fluid, and the tortuous flow channel further intensifies the interface update; the liquid is fully contacted at a very large relative speed under the conditions of high dispersion, high turbulence, strong mixing and rapid interface update, thereby realizing an efficient mass transfer and heat transfer process and chemical reaction process. The performance test data of the jacketed liner reactor based on supergravity are shown in Table 1.

[0036] It can be seen from Table 1 that when the frequency conversion of the supergravity generating unit 5 is between 35% and 50%, the maximum gas volume of the supergravity generating unit 5 is 110~190m 3 / h (compressed air volume). Compared with the conventional jacketed liner type reactor, the jacketed liner type reactor based on super gravity in the first specific embodiment can increase the load operation by 2 to 3 times.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
