Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology for generating leaf surface inhibitors, specifically a dual-function synthesis reaction vessel for generating leaf surface inhibitors using a barrier-chelation method. Background Technology

[0002] The barrier-chelation bifunctional synthesis reactor used to generate leaf surface barrier agents is a chemical equipment specifically designed for the simultaneous preparation of barrier agents and chelating agents.

[0003] In the prior art, such as in publication number CN205886851U, a reaction vessel is disclosed. It includes a reaction vessel body and a jacket disposed outside the reaction vessel body. A stirring device is located at the top of the reaction vessel body, and a feed inlet is located on one side of the stirring device at the top of the reaction vessel body. A discharge outlet is located at the bottom of the reaction vessel body. The key feature is that a temperature measuring device is located at the top of the reaction vessel body, with its lower end extending to the lower part of the reaction vessel body. The inner surface of the reaction vessel body is covered with a glass-lined layer that is resistant to low temperatures and acid / alkali corrosion. This reaction vessel is both resistant to low temperatures and acid / alkali corrosion.

[0004] While the aforementioned patents can enhance the low-temperature resistance and acid / alkali corrosion resistance of the reactor by adding a glass layer, the traditional single-reactor preparation method, which involves mixing the two, can lead to reaction failure, such as degradation of the chelating agent or precipitation of silicate. This makes it unsuitable for the simultaneous preparation of both the inhibitor and the chelating agent, and the production efficiency is relatively slow. Furthermore, the synthesis of organic chelating agents often involves flammable solvents, and silicate precursors may release hydrogen gas in high-temperature alkaline environments. Additionally, chelating agents are easily oxidized and fail in oxygen-rich environments, and there is a lack of structural protection against explosion and oxidation during processing.

[0005] Therefore, this invention provides a dual-function synthesis reactor for generating leaf surface inhibition control agents, which combines inhibition control and chelation. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a dual-function synthesis reactor for generating leaf surface inhibitors, which solves the problems of reaction failure caused by mixing the two in traditional single reactors, such as degradation of the chelating agent or silicate precipitation, making it unsuitable for the simultaneous preparation of inhibitors and chelating agents, and resulting in slow production efficiency. Furthermore, the synthesis of organic chelating agents often involves flammable solvents, and silicate precursors may release hydrogen gas in high-temperature alkaline environments. Additionally, chelating agents are easily oxidized and fail in oxygen-rich environments, and there is a lack of structural protection against explosion and oxidation during processing.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a dual-function synthesis reactor for generating leaf surface inhibitors, comprising a reactor, wherein the reactor has an axisymmetrically arranged inhibitor reaction chamber and a chelating agent reaction chamber, an equipment plate is fixedly connected inside the reactor, the equipment plate has mounting holes at both ends and oxygen sensors are sleeved in the mounting holes, an inhibition component is provided on the top surface of the reactor and a reaction component is provided on the surface;

[0008] The suppression component includes two air inlets symmetrically opened on the top surface of the reactor. Solenoid valve tubes are connected through the surfaces of the two air inlets. An air inlet pipe is sleeved on the top end of the solenoid valve tube, and an inert gas source is connected to the top end of the air inlet pipe.

[0009] The reaction assembly includes two cavities located inside the reactor and respectively enclosing the control agent reaction chamber and the chelating agent reaction chamber. One of the cavities has a heating plate installed inside, and a temperature controller is electrically connected to the surface of the heating plate. A device box is installed on the surface of the temperature controller and is fixedly connected to one side of the outer surface of the reactor. The other cavity has several transducers installed inside, and an ultrasonic generator is electrically connected to the surface of each transducer. The ultrasonic generator is fixedly connected to the other side of the outer surface of the reactor.

[0010] Preferably, the two oxygen sensors are respectively disposed inside the resist agent reaction chamber and the chelating agent reaction chamber. The oxygen sensors monitor the oxygen concentration in the resist agent reaction chamber and the chelating agent reaction chamber in real time and trigger the opening and closing of the solenoid valve tube.

[0011] Preferably, the heating plate regulates the temperature of the inhibitor reaction chamber to a constant temperature via the temperature controller.

[0012] Preferably, the transducer provides ultrasonic assistance to the chelating agent reaction chamber through the ultrasonic generator to enhance the complexation reaction.

[0013] Preferably, a pressure relief valve is connected through the side of the reactor. The pressure relief valve is connected to the common cavity of the control agent reaction chamber and the chelating agent reaction chamber and releases gas when there is overpressure.

[0014] Preferably, the mounting holes at both ends of the device plate are aligned with the central axes of the control agent reaction chamber and the chelating agent reaction chamber, respectively.

[0015] Beneficial effects

[0016] This invention provides a dual-functional synthesis reactor for generating leaf surface inhibitors, combining inhibition and chelation. Compared with existing technologies, it offers the following advantages:

[0017] 1. The dual-function synthesis reactor for generating leaf surface inhibitors, through the axisymmetric chamber design of the inhibitor reaction chamber and the chelator reaction chamber, combined with the constant temperature control of the heating plate and the ultrasonic assistance of the transducer, enables the simultaneous occurrence of the dual reactions of alkaline high-temperature synthesis of the inhibitor and neutral ultrasonic complexation of the chelator, avoiding cross-contamination, improving product purity and reaction efficiency.

[0018] 2. The dual-function synthesis reactor for generating leaf surface inhibitors uses an oxygen sensor to monitor the oxygen concentration in both chambers in real time. The electromagnetic valve of the linkage inhibition component injects inert gas, and the pressure relief valve releases overpressure.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides two technical solutions:

[0026] Figures 1-4The first embodiment is shown: a dual-function synthesis reactor for generating leaf surface inhibitors, comprising a reactor 1, wherein an inhibitor reaction chamber 2 and a chelating agent reaction chamber 3 are symmetrically arranged inside the reactor 1, an equipment plate 4 is fixedly connected inside the reactor 1, and an oxygen sensor 5 is fitted into the two ends of the equipment plate 4. An inhibition component 6 is provided on the top surface of the reactor 1, and a reaction component 7 is provided on the surface of the reactor 1. The reaction component 7 includes two cavities opened inside the reactor 1 and respectively enclosing the inhibitor reaction chamber 2 and the chelating agent reaction chamber 3. An electric heating plate 71 is fitted inside one cavity, and a temperature controller 72 is electrically connected to the surface of the electric heating plate 71. An equipment box 73 is fitted onto the surface of the temperature controller 72 and is fixedly connected to one side of the outer surface of the reactor 1. A plurality of transducers 74 are fitted inside the other cavity, and an ultrasonic generator 75 is electrically connected to the surface of the transducers 74 and is fixedly connected to the other side of the outer surface of the reactor 1.

[0027] Specifically, a Thermo Scientific HTP-300 heating plate 71 is installed in the inhibitor reaction chamber 2. The heating plate 71 precisely controls the reaction temperature through an OMRON E5CC temperature controller 72, which is integrated into an equipment box 73 and electrically connected to the heating plate 71. The equipment box 73 is fixed to the outer wall of the reactor 1. A Branson HCL-0808 transducer 74 is embedded in the chelating agent reaction chamber 3. The transducer 74 is electrically connected to a Branson 2000X ultrasonic generator 75, which is fixed to the outer wall of the other side of the reactor 1 and provides ultrasonic energy to the chelating agent reaction chamber 3 through the transducer 74. The inhibitor reaction chamber 2 and the chelating agent reaction chamber 3 are isolated by an equipment plate 4. The mounting holes at both ends of the equipment plate 4 are aligned with the central axes of the two chambers and fitted with Maxell... The oxygen sensor 5 of MX-01 monitors the oxygen concentration in both chambers in real time. Through the coordinated control of the heating plate 71, temperature controller 72, transducer 74 and ultrasonic generator 75, the resistive agent reaction chamber 2 and chelating agent reaction chamber 3 respectively achieve efficient stepwise synthesis of silicate high-temperature film formation and chelating agent ultrasonic complexation, improving product purity and reducing cross-contamination rate to below 5%.

[0028] In this embodiment, the suppression component 6 includes two air inlets 61 that are symmetrically opened on the top surface of the reactor 1. The surfaces of the two air inlets 61 are connected to a solenoid valve tube 62. The top end of the solenoid valve tube 62 is fitted with an air inlet pipe 63, and the top end of the air inlet pipe 63 is connected to an inert gas source.

[0029] Specifically, when the oxygen sensor 5 detects that the oxygen concentration in the control agent reaction chamber 2 or the chelating agent reaction chamber 3 exceeds the standard, it triggers the opening of the corresponding Bürkert 6011 solenoid valve tube 62 in the suppression component 6. The solenoid valve tube 62 is connected to a high-purity nitrogen source through the air inlet pipe 63 and injects inert gas into the corresponding chamber. At the same time, a Leser 5260 pressure relief valve 8 is connected through the side of the reactor 1. The pressure relief valve 8 is connected to the shared cavity of the two reaction chambers and automatically releases pressure when ultrasonic cavitation or high-temperature hydrogen production causes abnormal pressure. Through the linkage protection of the oxygen sensor 5, the solenoid valve tube 62 and the pressure relief valve 8, the risk of hydrogen accumulation in the control agent reaction chamber 2 and the oxidation failure problem in the chelating agent reaction chamber 3 are suppressed simultaneously, reducing the safety accident rate by 90% and the chelating agent activity retention rate by more than 95%.

[0030] Figures 1-4 The second embodiment is shown. The main difference from the first embodiment is that two oxygen sensors 5 are respectively disposed inside the control agent reaction chamber 2 and the chelating agent reaction chamber 3. The oxygen sensors 5 monitor the oxygen concentration in the control agent reaction chamber 2 and the chelating agent reaction chamber 3 in real time and trigger the opening and closing of the solenoid valve tube 62.

[0031] Specifically, oxygen sensors 5 are embedded inside the control agent reaction chamber 2 and the chelating agent reaction chamber 3, respectively. They are fixed through the mounting holes of the equipment board 4 and monitor the oxygen concentration in the two chambers in real time. When the oxygen concentration exceeds the threshold, the solenoid valve tube 62 of the suppression component 6 is triggered to open, and inert gas is injected into the corresponding chamber through the air inlet pipe 63 to form a low-oxygen environment. This linkage design simultaneously suppresses the risk of hydrogen explosion in the control agent reaction chamber 2 and the oxidation failure of the chelating agent reaction chamber 3, reducing the safety accident rate and improving the retention rate of chelating agent activity.

[0032] The heating plate 71 regulates the temperature of the inhibitor reaction chamber 2 to a constant temperature via the temperature controller 72;

[0033] Specifically, the heating plate 71 is installed around the reaction chamber 2 of the resistance agent and the temperature is controlled to a constant temperature by the temperature controller 72. The temperature controller 72 is integrated in the equipment box 73 to provide real-time feedback of temperature data, so that the silicate precursor can be synthesized efficiently at a stable high temperature. This constant temperature control increases the film formation rate of the resistance agent by 25%, increases the film density, and improves the leaf surface resistance efficiency.

[0034] Transducer 74 provides ultrasonic assistance to chelating agent reaction chamber 3 through ultrasonic generator 75 to enhance complexation reaction;

[0035] Specifically, transducers 74 are evenly distributed around the chelating agent reaction chamber 3 and connected to ultrasonic generator 75. Ultrasonic energy is transmitted to the reaction liquid through transducers 74 to induce cavitation effect and accelerate the coordination reaction between metal ions and chelating agent. This ultrasonic assistance shortens the complexation time, increases the complexation rate of chelating agent, and reduces the viscosity of the reaction liquid to avoid spray blockage.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] Working principle: The reactor 1 achieves dual-function independent synthesis through the internally axisymmetrically arranged control agent reaction chamber 2 and chelating agent reaction chamber 3. The heating plate 71 around the control agent reaction chamber 2 maintains a constant temperature environment under the control of the temperature controller 72, which promotes the hydrolysis and condensation of the silicate precursor into a film under alkaline conditions. The transducer 74 around the chelating agent reaction chamber 3 outputs ultrasonic waves through the ultrasonic generator 75, which uses the cavitation effect to break up the metal ion agglomerates and accelerate their coordination and complexation with the chelating agent, while maintaining a neutral environment. The oxygen sensors 5 installed at both ends of the equipment plate 4 monitor the oxygen concentration of the two chambers in real time. When the oxygen concentration exceeds 18%, the solenoid valve tube 62 of the suppression component 6 is triggered to open, and inert gas is injected into the corresponding chamber through the inlet pipe 63 to suppress the risk of oxidation or explosion. The pressure relief valve 8 connected by the shared cavity of the two reaction chambers automatically releases pressure when the internal pressure exceeds the limit. Finally, through the synergistic mechanism of chamber temperature control, ultrasonic enhancement, oxygen control interlock, and pressure redundancy, the efficient and safe synchronous synthesis of the control agent and chelating agent is achieved.
