Description

Technical Field

[0001] This invention relates to the field of olefin hydration and paraffin gas-liquid-solid oxidation reactions, and particularly to a multiphase reaction apparatus for olefin hydration and paraffin oxidation. Background Technology

[0002] Olefin hydration and paraffin gas-liquid-solid oxidation reactions are both fundamental reactions in organic synthesis and play an important role in energy chemical, fine chemical and materials fields. Among them, the heterogeneous reaction of olefin hydration and paraffin oxidation refers to the gas-solid heterogeneous reaction of olefins and water on the surface of a solid catalyst (such as acidic molecular sieve) to produce alcohols during olefin hydration.

[0003] A search revealed that the document with publication number "CN218459510U" mentions "an automatic reactor cleaner, comprising a tank, a support column provided on the outside of the bottom end of the tank, a fixed sleeve provided on the outside of the bottom end of the support column, a fixed frame fixed on both sides of the fixed sleeve, a rotating bracket movably mounted on the fixed frame, and an installation shaft provided inside the bottom end of the rotating bracket." In use, this utility model fixes the fixed sleeve to the outside of the bottom end of the support column, fixes the fixed frame to both sides of the fixed sleeve, movably mounts the rotating bracket to the bottom end of the fixed frame, and then movably mounts wheels on the inside of the bottom end of the rotating bracket via the installation shaft. This allows the reactor to move flexibly via the wheels, making it more convenient to use. A telescopic rod movably mounted at the output end of the support column moves downwards, supporting the tank. The height and level of the reactor can be adjusted by adjusting the length of the telescopic rod's downward movement.

[0004] However, olefin hydration and paraffin oxidation are important chemical reaction processes in chemical production. Traditional reaction equipment has some limitations in handling these two types of reactions. In the paraffin oxidation reaction, some existing reaction equipment has poor temperature control, which can easily lead to the problem of re-solidification after the molten paraffin has dissolved. At the same time, the catalyst supply method is not precise enough, making it difficult to ensure sufficient and uniform contact between the catalyst and the paraffin solution, thus reducing catalytic efficiency. Furthermore, in the liquid separation process after the reaction, it is not easy to accurately separate the flow and components, making it difficult to effectively distinguish different types of liquid products, which affects the purity of the product and subsequent processing.

[0005] Therefore, we provide a heterogeneous reaction apparatus for olefin hydration and paraffin oxidation to solve the above problems. Summary of the Invention

The catalyst supply component includes a catalyst inlet welded to the upper outer side of the reaction tank. A microchannel disperser is installed on the inner side of the catalyst inlet. A liquefied catalyst supply tank is installed on the outer side of the catalyst inlet. A multiphase reaction catalytic separation component is connected to the right side of the deposition cone bottom. The multiphase reaction catalytic separation component includes a drain pipe welded to the right side of the deposition cone bottom. A liquid pump is installed at the end of the drain pipe. A liquid separator is connected to the lower pipe of the liquid pump.

[0008] As a further description of the above technical solution:

[0009] The multiphase reaction heating assembly includes an electric heater welded to the surface of the reaction vessel. Heating tubes are welded to the inner wall of the reaction vessel. A temperature controller is provided on the outside of the electric heater. The heating tubes are electrically connected to the temperature controller and the electric heater.

[0010] As a further description of the above technical solution:

[0011] A stirring motor is installed on the upper side of the reaction vessel, and a stirring rod is connected to the middle of the lower side of the stirring motor. A bottom cone mixing rod is installed at the end of the stirring rod.

[0012] As a further description of the above technical solution:

[0013] The bottom cone mixing cone rod and the bottom of the deposition cone are connected by a slot, and the electrically controlled high-pressure air pump and the bottom cone mixing cone rod form a gas-liquid mixing structure through the bottom of the deposition cone.

[0014] As a further description of the above technical solution:

[0015] The microchannel disperser is connected to the catalyst inlet by a slot, and the microchannel disperser has micron-level channels distributed inside.

[0016] As a further description of the above technical solution:

[0017] A liquid separation electric control pump is installed on the right side of the liquid separation tank. An electric control valve is connected to the outer pipe of the liquid separation electric control pump. An alcohol liquid drain pipe is connected to the front side of the electric control valve. A liquid oxidized wax drain pipe is connected to the right side of the electric control valve. A water return pipe is connected to the rear side of the electric control valve. A water quality sensor is installed on the front side of the liquid separation electric control pump.

[0018] As a further description of the above technical solution:

[0019] The liquid separation electric control pump and the electric control valve are electrically connected, the water quality sensor and the electric control valve are electrically connected, and the water quality sensor and the liquid separation electric control pump are at the same horizontal level.

[0020] The beneficial effects of this invention are:

[0021] 1. This invention, by setting up a multiphase reaction heating component and a catalytic supply component, allows molten paraffin solution to be poured into the reaction vessel when needed. At this time, the temperature controller controls the heating tube through the electric heater to continuously heat the paraffin solution, thereby maintaining a constant internal temperature of the reaction vessel and ensuring that the paraffin solution reacts at a suitable temperature. Furthermore, when the catalyst is injected into the catalyst inlet through the liquefied catalyst supply tank, the microchannel disperser in the catalyst inlet will uniformly disperse the liquefied catalyst into micron-sized particles, thereby facilitating full contact between the catalyst and the paraffin solution, improving the catalytic effect, and ensuring the stability and high efficiency of the reaction process.

[0022] 2. This invention utilizes a multiphase reaction mixing component. A stirring motor drives a stirring rod and a bottom mixing cone to stir the mixture, thereby fully mixing the paraffin solution, oxygen, and catalyst within the reaction vessel to ensure uniform reaction. The bottom mixing cone rotates along its interior as the stirring motor rotates. At this time, an electrically controlled high-pressure gas pump injects oxygen directly into the bottom of the deposition cone. As the bottom mixing cone rotates, oxygen and paraffin solution form a uniform gas-liquid mixture layer at the bottom of the deposition cone, further promoting reaction efficiency and ensuring that the paraffin solution is fully decomposed under high temperature and high pressure to generate a high-purity product.

[0023] 3. This invention, through the setting of a multiphase reaction catalytic separation component, uses a water quality sensor to sense the current water level and liquid type in real time. Depending on the type, different drain pipes are opened via electrically controlled valves to ensure precise separation of each liquid, thereby distinguishing alcohol liquids, liquid oxidized wax, and water. Alcohol liquids, liquid oxidized wax, and water then separate through their own sedimentation properties. Based on the current water level and liquid state, the flow rate of the liquid separation pump and the opening and closing of the electrically controlled valves are automatically adjusted. Depending on the type of liquid, the corresponding alcohol liquid drain pipe, liquid oxidized wax drain pipe, or water return pipe is opened, thereby achieving a highly efficient separation effect and ensuring the purity of each component. The water return pipe is connected to the reaction tank, and a portion of water is always accumulated at the bottom of the liquid separation tank to ensure that alcohol liquids and liquid oxidized wax do not mix at the bottom.

In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0035] Please see Figure 1-6 As shown, the present invention provides a technical solution: a multiphase reaction device for olefin hydration and paraffin oxidation, comprising a reaction tank 1, a multiphase reaction heating assembly 2 disposed in the middle of the reaction tank 1, a multiphase reaction mixing assembly 3 disposed inside the reaction tank 1, the multiphase reaction mixing assembly 3 including a deposition cone bottom 301 welded to the bottom of the reaction tank 1, an electrically controlled high-pressure gas pump 302 installed on the lower side of the deposition cone bottom 301, an exhaust port 306 disposed on the right side of the electrically controlled high-pressure gas pump 302, and a catalyst supply assembly 4 installed on the front side of the reaction tank 1. The catalyst supply assembly 4 includes a catalyst inlet 401 welded to the upper part of the outer side of the reaction tank 1. A microchannel disperser 402 is installed inside the catalyst inlet 401. A liquefied catalyst supply tank 403 is installed outside the catalyst inlet 401. A multiphase reaction catalytic separation assembly 5 is connected to the right side of the deposition cone bottom 301. The multiphase reaction catalytic separation assembly 5 includes a drain pipe 501 welded to the right side of the deposition cone bottom 301. A pump 502 is installed at the end of the drain pipe 501. A separatory tank 503 is connected to the lower pipe of the pump 502.

[0036] Furthermore, the multiphase reaction heating assembly 2 includes an electric heater 201 welded to the surface of the reaction vessel 1. Heating tubes 202 are welded to the inner wall of the reaction vessel 1. A temperature controller 203 is provided on the outside of the electric heater 201. The heating tubes 202 are electrically connected to the temperature controller 203 and the electric heater 201. When needed, molten paraffin solution is poured into the reaction vessel 1. At this time, the temperature controller 203 controls the heating tubes 202 to continuously heat the paraffin solution through the electric heater 201, thereby maintaining a constant internal temperature of the reaction vessel 1 and ensuring that the paraffin solution reacts at a suitable temperature.

[0037] Furthermore, a stirring motor 303 is installed on the upper side of the reaction vessel 1, and a stirring rod 304 is connected to the middle of the lower side of the stirring motor 303. A bottom cone mixing rod 305 is installed at the end of the stirring rod 304. When needed, the stirring motor 303 drives the stirring rod 304 and the bottom cone mixing rod 305 to stir, thereby fully mixing the paraffin solution, oxygen and catalyst in the reaction vessel 1 to ensure uniform reaction effect.

[0038] Furthermore, the bottom mixing cone 305 and the deposition cone bottom 301 are connected by a slot. The electrically controlled high-pressure air pump 302 and the bottom mixing cone 305 form a gas-liquid mixing structure through the deposition cone bottom 301. When needed, the bottom mixing cone 305 rotates along the inside of the bottom mixing cone 305 as the stirring motor 303 rotates. At this time, the electrically controlled high-pressure air pump 302 injects oxygen directly into the inside of the deposition cone bottom 301 from the bottom. As the bottom mixing cone 305 rotates, oxygen and paraffin solution form a uniform gas-liquid mixture layer in the deposition cone bottom 301, further promoting reaction efficiency and ensuring that the paraffin solution is fully decomposed under high temperature and high pressure to generate high-purity products.

[0039] Furthermore, the microchannel disperser 402 is connected to the catalyst inlet 401 by a slot. The microchannel disperser 402 has micron-sized channels distributed inside. When the catalyst is injected into the catalyst inlet 401 through the liquefied catalyst supply tank 403, the microchannel disperser 402 inside the catalyst inlet 401 will uniformly disperse the liquefied catalyst into micron-sized particles, thereby facilitating full contact between the catalyst and the paraffin solution, improving the catalytic effect, and ensuring the stability and efficiency of the reaction process.

[0040] Furthermore, a liquid dispensing electric pump 504 is installed on the right side of the dispensing tank 503. An electric control valve 505 is connected to the outer pipe of the dispensing electric pump 504. An alcohol liquid drain pipe 506 is connected to the front of the electric control valve 505, a liquid oxidized wax drain pipe 507 is connected to the right side of the electric control valve 505, and a water return pipe 508 is connected to the rear of the electric control valve 505. A water quality sensor 509 is installed on the front of the dispensing electric pump 504. When needed, the water quality sensor 509 monitors the current water level in the dispensing tank 503 in real time. The system distinguishes between alcohol liquids, liquid oxidized wax, and water based on their respective precipitation properties. Furthermore, it automatically adjusts the flow rate of the liquid separation pump 504 and the opening and closing of the electric control valve 505 according to the current liquid state at the water level. Depending on the type of liquid, it opens the corresponding alcohol liquid drain pipe 506, liquid oxidized wax drain pipe 507, or water return pipe 508, thereby achieving a highly efficient separation effect and ensuring the purity of each component. The water return pipe 508 is connected to the reaction tank 1.

[0041] Furthermore, the liquid separation electric control pump 504 is electrically connected to the electric control valve 505, and the water quality sensor 509 is electrically connected to the electric control valve 505. The water quality sensor 509 and the liquid separation electric control pump 504 are at the same horizontal level. When needed, the water quality sensor 509 will sense the current water level and liquid type in real time. Depending on the type, different drain pipes 501 will be opened through the electric control valve 505 to ensure accurate liquid separation. A portion of water is always accumulated at the bottom of the liquid separation tank 503 to ensure that alcohol liquids and liquid oxidized wax do not mix at the bottom.

[0042] Working Principle: When needed, molten paraffin wax is first injected into reaction tank 1. Simultaneously, temperature controller 203 controls heating tube 202 via electric heater 201 to maintain the molten paraffin wax at a constant melting state and temperature. Then, liquid catalyst is injected into catalyst inlet 401 via liquefied catalyst supply tank 403. After passing through microchannel disperser 402, the catalyst is evenly dispersed and finally fed into reaction tank 1. Simultaneously, electrically controlled high-pressure gas pump 302 pressurizes oxygen and injects it into the sedimentation cone bottom 301. Once ready, stirring motor 303 drives stirring rod 304 and bottom cone mixing rod 305 to rotate. Stirring rod 304 mixes the molten paraffin wax solution, catalyst, and oxygen in reaction tank 1, improving the reaction effect. Bottom cone mixing rod 305 thoroughly mixes the oxygen and molten paraffin wax solution in sedimentation cone bottom 301. The gases generated during the catalytic process... The solution is discharged through exhaust port 306 for collection and reuse. After stirring, the pump 502 draws the reacted solution into the separatory tank 503 through the drain pipe 501. As the precipitation reaction occurs, water settles at the bottom, while the oxidized wax product floats on the water surface, and the alcohol product floats on top of the oxidized wax product. At this time, the water quality sensor 509 senses the type of liquid at the current liquid level. When the water quality sensor 509 senses water, it controls the separatory electric pump 504 and the electric valve 505 to start operating. The electric valve 505 opens the water return pipe 508 to send water back into the reaction tank 1. When the oxidized wax product drops to the position of the separatory electric pump 504, the water quality sensor 509 senses the change in type, and the electric valve 505 opens the liquid oxidized wax drain pipe 507 to discharge the oxidized wax product. Finally, the alcohol product is discharged through the alcohol liquid drain pipe 506, thus completing the use of the present invention.
