Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, and in particular to an organic oxidation reaction vessel device. Background Technology
[0002] In the industrial production of organic oxidation reactions, vapors containing reactants, intermediates, or solvents are continuously generated in the reactor. To avoid waste, these vapors are usually condensed and recovered through a condenser connected to the reactor. However, the condensed liquid (i.e., the oil phase liquid of reactants, intermediates, or solvents) contains a large amount of condensate (aqueous phase liquid), forming a liquid mixture. If this condensed liquid mixture is directly returned to the reactor, the condensate will have multi-dimensional adverse effects on the entire reaction system. On the one hand, the return of condensate will change the composition of the materials in the reactor, affecting the concentration and ratio of the reaction system, and thus the reaction time. For example, in some organic oxidation reactions with strict requirements on the concentration of raw materials, excessive condensate will reduce the concentration of reactants, resulting in a slower reaction rate. A reaction that could have been completed in a few hours may have taken several times longer. On the other hand, the introduction of condensate can also reduce the reaction conversion rate. For example, in certain specific organic oxidation synthesis reactions, the ideal conversion rate can reach 80%, but due to the influence of condensate, the conversion rate often only reaches about 60%, which seriously affects production efficiency and product output.
[0003] Existing reactors typically employ vacuum pumps to build up pressure and concentrate water, or separators to separate the aqueous phase for water removal. However, the above-mentioned reactor water removal devices are all complex in structure and have poor water removal effect.
[0004] Therefore, there is an urgent need to propose an organic oxidation reactor device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an organic oxidation reactor device that does not require the installation of separators or other equipment, has a simple structure and low cost, and can efficiently, stably and accurately discharge the condensate (aqueous phase) from the recovery tank, thereby improving the material (oil phase) recovery rate.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] An organic oxidation reactor apparatus, comprising:
[0008] The vessel body allows materials to undergo a chemical reaction within it, generating hot steam.
[0009] A condenser, the inlet of which is connected to the vessel body, allows the hot steam to enter the condenser and condense into a liquid mixture, the liquid mixture comprising an oil phase and a water phase;
[0010] A recovery tank is located above the reactor body and is connected to the outlet of the condenser. The liquid mixture can flow back to the recovery tank and separate into layers within the recovery tank, with the oil phase on the upper layer and the water phase on the lower layer.
[0011] A reflux pipe, the first end of which is connected to the reactor body, and the second end of which extends into the recovery tank and is placed in the upper oil phase;
[0012] A drain pipe, one end of which is connected to the bottom of the recycling tank.
[0013] As an optional technical solution for an organic oxidation reactor device, the reflux pipe is vertically arranged, and the reflux pipe and the drain pipe are respectively arranged at opposite ends of the recovery tank; the second end is located in the middle of the upper layer.
[0014] As an optional technical solution for an organic oxidation reactor device, the second end is provided with a 45-degree inclined opening, and the inclined opening faces the center of the recovery tank.
[0015] As an optional technical solution for an organic oxidation reactor, the reflux pipe is equipped with a filter element, which can filter the oil phase returning to the reactor body.
[0016] As an optional technical solution for organic oxidation reactor equipment, the reflux pipe is equipped with a one-way valve.
[0017] As an optional technical solution for an organic oxidation reactor, the side wall of the recovery tank is provided with a first sight glass and a second sight glass. The first sight glass is configured to correspond to the upper layer where the oil phase is located, and the second sight glass is configured to correspond to the lower layer where the aqueous phase is located.
[0018] As an optional technical solution for organic oxidation reactor devices, the inner wall of the recovery tank is also equipped with a liquid level sensor.
[0019] As an optional technical solution for an organic oxidation reactor device, a drain outlet is provided at the lowest point of the bottom of the recovery tank, and the drain pipe is connected to the recovery tank through the drain outlet.
[0020] As an optional technical solution for the organic oxidation reactor device, the organic oxidation reactor device also includes a ton tank, which is located below the recovery tank. The other end of the drain pipe is connected to the ton tank, and a solenoid valve is provided on the drain pipe.
[0021] As an optional technical solution for an organic oxidation reactor device, the organic oxidation reactor device also includes a weight detection element, and the ton container is located on the weight detection element.
[0022] The beneficial effects of this utility model are:
[0023] The organic oxidation reactor device provided by this utility model includes a reactor body, a condenser, a recovery tank, and a reflux pipe. Materials can undergo a chemical reaction within the reactor body, generating hot steam. The inlet of the condenser is connected to the reactor body, allowing the hot steam to enter and condense into a liquid mixture comprising an oil phase and a water phase. The recovery tank is located above the reactor body and connected to the outlet of the condenser, enabling the liquid mixture to flow back into the recovery tank. Since oil is lighter than water, the liquid mixture will separate into layers within the recovery tank, with the oil phase on top and the water phase on the bottom, thus achieving oil and water phase separation. The first end of the reflux pipe is connected to the reactor body, and the second end extends into the recovery tank and is placed in the upper oil phase layer (i.e., located in the oil phase layer), allowing the separated oil phase to flow back to the reactor body through the reflux pipe to continue participating in the chemical reaction, achieving material recovery and utilization. One end of the drain pipe is connected to the bottom of the recovery tank, allowing the separated water phase to be discharged.
[0024] Therefore, this organic oxidation reactor can utilize the gravity characteristics of the oil and water phases to separate liquid mixtures into layers, achieving automatic separation of the oil and water phases without the need for separators or other equipment. It features a simple structure and low cost. The reflux pipe is inserted into the oil phase layer of the recovery tank, ensuring that only the oil phase above the second end of the reflux pipe enters, preventing the liquid mixture at the interface between the water and oil phase layers from entering the reflux pipe. This prevents the recovered oil phase from being mixed with water. The drain pipe is located at the bottom of the recovery tank, providing excellent drainage and preferentially draining the water phase at the bottom, preventing the liquid mixture at the interface between the water and oil phase layers from entering the drain pipe. This also prevents the discharged water phase from being mixed with oil. Simultaneously, the reflux pipe and drain pipe do not interfere with each other, enabling efficient, stable, and precise discharge of condensate (water phase) from the recovery tank, improving the material (oil phase) recovery rate.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0031] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0032] This embodiment provides an organic oxidation reactor device that does not require the installation of separators or other equipment, has a simple structure and low cost; and can efficiently, stably and accurately discharge the condensate (aqueous phase) from the recovery tank, thereby improving the material (oil phase) recovery rate.
[0033] Specifically, such as Figure 1As shown, the organic oxidation reactor includes a reactor body 100, a condenser 200, a recovery tank 300, and a reflux pipe 400. Materials can undergo a chemical reaction within the reactor body 100, generating hot steam. The inlet of the condenser 200 is connected to the reactor body 100, allowing the hot steam to enter and condense into a liquid mixture comprising an oil phase and a water phase. The recovery tank 300 is located above the reactor body 100 and is connected to the outlet of the condenser 200. The liquid mixture can flow back to the recovery tank 300, where it separates into layers: the oil phase is on top, and the water phase is on the bottom. The first end 410 of the reflux pipe 400 is connected to the reactor body 100, and the second end 420 extends into the recovery tank 300 and is placed in the upper oil phase. One end of the drain pipe 500 is connected to the bottom of the recovery tank 300.
[0034] It should be noted that the top of the recovery tank 300 is connected to the bottom outlet of the condenser 200, that is, the liquid mixture flows back from the top of the recovery tank 300 to the recovery tank 300; and the return pipe 400 is connected to the return port at the top of the reactor body 100 through a flange, so that the separated recovered oil phase enters the reactor body 100 from the top of the reactor body 100 to continue to participate in the chemical reaction.
[0035] Based on the above design, the material can undergo a chemical reaction within the reactor body 100, generating hot steam. The inlet of the condenser 200 is connected to the reactor body 100, allowing the hot steam to enter and condense into a liquid mixture comprising an oil phase and a water phase. The recovery tank 300 is located above the reactor body 100 and is connected to the outlet of the condenser 200, enabling the liquid mixture to flow back to the recovery tank 300. Since oil is lighter than water, the liquid mixture will separate into layers within the recovery tank 300, with the oil phase on top and the water phase on the bottom, thus forming an oil phase layer and a water phase layer, achieving separation of the oil and water phases. The first end 410 of the reflux pipe 400 is connected to the reactor body 100, and the second end 420 extends into the recovery tank 300 and is placed in the upper oil phase (i.e., in the oil phase layer), so that the separated oil phase can flow back to the reactor body 100 through the reflux pipe 400 to continue participating in the chemical reaction, realizing the recycling of materials; one end of the drain pipe 500 is connected to the bottom of the recovery tank 300, so that the separated water phase is discharged. Therefore, this organic oxidation reactor device can utilize the gravity characteristics of the oil phase and water phase to separate the liquid mixture into layers, realizing the automatic separation of the oil phase and water phase without the need for separators or other equipment, and has a simple structure and low cost. The return pipe 400 is inserted into the oil phase layer of the recovery tank 300, allowing only the oil phase above the second end 420 of the return pipe 400 to enter the return pipe 400, preventing the liquid mixture at the interface between the water phase layer and the oil phase layer from entering the return pipe 400, thus preventing the water phase from being mixed in with the recovered oil phase; the drain pipe 500 is located at the bottom of the recovery tank 300, providing good drainage and allowing the water phase at the bottom to be discharged preferentially, preventing the liquid mixture at the interface between the water phase layer and the oil phase layer from entering the drain pipe 500, thus preventing the oil phase from being mixed in with the discharged water phase; at the same time, the return pipe 400 and the drain pipe 500 do not interfere with each other, thus enabling efficient, stable and accurate discharge of condensate (water phase) from the recovery tank 300, improving the material (oil phase) recovery and utilization rate.
[0036] It should be noted that the reflux pipe 400 and drain pipe 500 in this organic oxidation reactor are all corrosion-resistant pipes, for example, they can be made of 316L stainless steel or polytetrafluoroethylene.
[0037] In this embodiment, the nominal diameter of both the return pipe 400 and the drain pipe 500 is 15mm; and the wall thickness of the drain pipe is greater than or equal to 3mm.
[0038] Optionally, the reflux pipe 400 is vertically arranged to facilitate the smooth return of the oil phase to the reactor body 100. Furthermore, the reflux pipe 400 and the drain pipe 500 are respectively located at opposite ends of the recovery tank 300, increasing the distance between them and minimizing the turbulence caused by the separate discharge of liquid from the reflux pipe 400 and the drain pipe 500. The second end 420 is located in the middle of the upper layer, ensuring a sufficient continuous flow of oil phase into the reflux pipe 400 while avoiding excessive proximity to the aqueous phase.
[0039] Specifically, it needs to be preset according to the tank diameter of the recovery tank 300 and the layering ratio of the oil phase and water phase. For example, when the normal upper layer height (i.e., oil phase layer) in the recovery tank 300 is 10cm, the distance between the second end 420 of the return pipe 400 and the bottom of the recovery tank 300 is set to 8cm-12cm to ensure that the second end 420 only contacts the upper oil phase.
[0040] To further facilitate the entry of the oil phase into the reflux pipe 400, the second end 420 is provided with a 45-degree inclined opening, and the inclined opening faces the center of the recovery tank 300.
[0041] To prevent the oil phase from carrying fine impurities and clogging the return pipe 400, a filter element 600 is provided inside the return pipe 400. The filter element 600 can filter the oil phase returning to the reactor body 100.
[0042] In this embodiment, the filter element 600 is disposed near the second end 420 of the return pipe 400; the filter element 600 is a corrosion-resistant filter screen, and different specifications of filter screens can be selected according to the particle size of impurities in the actual situation.
[0043] In this embodiment, a one-way valve (not shown in the figure) is provided on the reflux pipe 400. Specifically, the one-way valve can be set at the position of the reflux pipe 400 near the second end 420, or at the reflux port of the vessel body 100, to prevent the negative pressure of the vessel body 100 from causing the medium to be drawn back.
[0044] Optionally, the side wall of the recovery tank 300 is provided with a first sight glass 310 and a second sight glass 320. The first sight glass 310 is corresponding to the upper layer (i.e., oil phase layer) where the oil phase is located, and the second sight glass 320 is corresponding to the lower layer (i.e., water phase layer) where the water phase is located. Specifically, the first sight glass 310 corresponds to the oil phase layer monitoring area (one-third of the tank height from the top of the recovery tank 300), and the second sight glass 320 corresponds to the water phase layer monitoring area (one-quarter of the tank height from the bottom of the recovery tank 300), which facilitates manual confirmation of the oil-water separation state of the liquid mixture.
[0045] Optionally, a drain outlet is provided at the lowest point of the bottom of the recycling tank 300, and the drain pipe 500 is connected to the recycling tank 300 through the drain outlet to maximize the discharge of water phase from the recycling tank 300.
[0046] Furthermore, the organic oxidation reactor also includes a ton tank 810, which is located below the recovery tank 300. The other end of the drain pipe 500 is connected to the ton tank 810, and the discharged water phase is placed in the ton tank 810. A solenoid valve 700 is provided on the drain pipe 500 to control the opening and closing of the drainage of the recovery tank 300.
[0047] Furthermore, the organic oxidation reactor also includes a weight detection element 820, on which a ton 810 is located to detect the cumulative weight of the aqueous phase (condensate) inside the ton 810.
[0048] The weight detection component 820 can be a weighing platform or a weighing sensor.
[0049] In this embodiment, the weight detection element 820 is connected to the PLC controller to monitor the cumulative weight of the water phase (condensate) in the ton 810 in real time. When the condensate in the ton 810 reaches the set value, the warning light 830, which is electrically connected to the weight detection element 820, alarms to prompt the replacement of the ton 810.
[0050] Optionally, a liquid level sensor 330 is also installed on the inner wall of the recovery tank 300. Specifically, a high-precision liquid level sensor (capacitive type, measurement accuracy ±1mm) can be installed in the lower middle area of the inner wall of the recovery tank 300 (covering the upper limit of the aqueous phase layer to the bottom of the oil phase layer, avoiding the sedimentation area at the bottom of the tank and the steam area at the top of the tank) to collect the liquid level data of the oil phase layer and the aqueous phase layer in real time. The liquid level data signal is transmitted to the PLC controller, which not only serves as the basis for liquid discharge control, but also simultaneously monitors the height of the oil phase layer (if the oil phase layer is too low, a feeding warning is triggered for the reactor body 100; if the aqueous phase layer is too high, a condensate discharge warning is triggered).
[0051] In this embodiment, a series structure of "manual shut-off valve + automatic solenoid valve" is set (the solenoid valve 700 has an adjustment range of 0-50L / h and a response time of ≤2s). The PLC controller is linked to the solenoid valve 700 according to the signal of the liquid level sensor 330: when the liquid level of the aqueous phase reaches the set upper limit (such as 60% of the total volume of the recovery tank 300, or close to the second end 420 of the return pipe 400 in the oil phase), the solenoid valve 700 is fully opened to drain water; when the liquid level drops to the set lower limit (such as 20% of the total volume of the recovery tank 300, 5cm-8cm from the bottom of the tank, avoiding sedimentation), the solenoid valve 700 is closed to prevent air from entering or water from backflowing due to venting; the manual valve is used as an emergency backup for easy maintenance.
[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
