Description

Technical Field

[0001] This utility model relates to the field of reagent preparation device technology, specifically to an absorbent formulation preparation device and its automated continuous production system. Background Technology

[0002] With the increasing severity of global climate change, carbon dioxide (CO2), as a major greenhouse gas, has become a focal point of international concern for emission control. Capture and treatment technologies for CO2 and other greenhouse gases have also received widespread attention. Organic amine absorbents, as highly efficient CO2 capture media, have their performance and efficiency during preparation significantly impacting overall production efficiency and even the capture efficiency of CO2 and other greenhouse gases. However, existing organic amine absorbent preparation equipment suffers from numerous problems:

[0003] (1) Current solution preparation methods rely on manual operation, which is not only inefficient, but also lacks the accuracy of the amount of materials added, which can easily lead to ratio errors and clogging problems.

[0004] (2) Current solution preparation technology is not precise in temperature control and has a relatively simple heating and cooling method, which seriously limits the increase in output;

[0005] (3) Key parameters such as liquid level and temperature need to be manually monitored, which poses a significant safety risk;

[0006] (4) Poor coordination between components makes it difficult to achieve continuous production.

[0007] The aforementioned defects severely affect the yield and quality of organic amine absorbents, increase production costs, and reduce the capture efficiency of greenhouse gases such as carbon dioxide.

[0008] Therefore, in order to solve the problems of insufficient quality and yield of absorbent preparation and overcome the shortcomings of existing technologies, there is an urgent need for an absorbent formulation device and its automated continuous production system that can effectively improve the preparation efficiency and quality of absorbents. Utility Model Content

[0009] The present invention aims to provide an absorbent formulation preparation device and its automated continuous production system, which solves the problems of insufficient quality and yield in existing absorbent preparation.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] An apparatus for preparing an absorbent formulation includes a reaction mechanism, a temperature control mechanism, a water supply mechanism, and a conveying mechanism. The reaction mechanism includes a reaction vessel and a stirring structure disposed on top of the reaction vessel. The outlet of the water supply mechanism is located above the inlet of the reaction vessel. The temperature control mechanism includes a temperature measuring component and a heat exchange component. The heat exchange component is disposed at the bottom of the reaction vessel, and the temperature measuring component is disposed inside the reaction vessel. The conveying mechanism includes a solid conveying mechanism for transporting solid raw materials and a liquid conveying mechanism for transporting liquid solvents.

[0012] The principles and advantages of this scheme are:

[0013] 1. Solving the problems of low efficiency and insufficient accuracy in manual operation: This solution incorporates a dedicated conveying mechanism, including solid conveying and liquid conveying mechanisms, to automatically transport solid raw materials and liquid solvents, effectively changing the current solution preparation method that relies on manual operation. Traditional manual operation suffers from low efficiency and insufficient accuracy in material feeding. This device's conveying mechanism can more precisely control the input of solid raw materials and liquid solvents, reducing proportioning errors and improving the accuracy of absorbent preparation. Simultaneously, the reduced proportioning errors also lower the probability of clogging caused by improper proportioning, making the absorbent preparation process smoother and further improving overall production efficiency.

[0014] 2. This solution achieves efficient and accurate temperature control: The temperature control mechanism incorporates a temperature measuring component and a heat exchange component. The temperature measuring component, located inside the reaction vessel, can measure the temperature within the vessel in real time and accurately. Compared to existing solution preparation technologies with limited temperature control precision, this device can obtain more precise reaction temperature data. The heat exchange component, located at the bottom of the reaction vessel, provides a more flexible heat exchange method, moving beyond the current simplistic heating and cooling approach. Based on the temperature data fed back by the measuring component, the operating status of the heat exchange component can be adjusted promptly to heat or cool the reaction vessel, thereby controlling the reaction temperature more precisely. This meets the stringent temperature requirements during absorbent preparation and helps increase absorbent yield. Appropriate and precise temperature control ensures the smooth progress of the reaction, avoiding incomplete reactions or side reactions caused by unsuitable temperatures, thus increasing yield.

[0015] 3. This solution addresses the safety risks associated with manual monitoring of key parameters: By installing temperature measurement components, this solution measures the temperature inside the reaction vessel in real time, eliminating the need for continuous manual monitoring. This reduces human intervention and lowers the safety risks to operators exposed to hazardous environments. In high-temperature or corrosive reaction environments, manual monitoring carries the risk of burns or chemical injuries, while automatic monitoring avoids these risks and ensures operator safety.

[0016] 4. This scheme achieves continuous production: The scheme includes a reaction mechanism, a temperature control mechanism, a water supply mechanism, and a conveying mechanism, with clear functional divisions and layouts among these mechanisms. The stirring structure in the reaction mechanism stirs and thoroughly mixes the solid raw materials and liquid solvent; the temperature control mechanism monitors and adjusts the reaction temperature in real time; the water supply mechanism replenishes the reaction vessel with water; and the conveying mechanism accurately delivers the raw materials. These mechanisms cooperate with each other to jointly contribute to the preparation of the absorbent. Compared to existing systems where the coordination between components is poor, this device, through its rational structural design and functional layout, better achieves coordinated operation between components, enabling the entire absorbent preparation process to proceed more stably and continuously. This effectively reduces downtime and adjustment time during production, improves production efficiency, and increases output per unit time.

[0017] Furthermore, the liquid conveying mechanism includes a hoist and a tilter disposed on top of the hoist. The hoist lifts the container containing the liquid solvent above the reaction vessel, and the tilter is used to tilt the container for feeding. The solid conveying mechanism includes a metering conveyor belt.

[0018] Beneficial Effects: To facilitate management and improve efficiency, the conveying mechanism is divided into a solid conveying mechanism and a liquid conveying mechanism, simultaneously transporting both solid and liquid materials. Solid materials are precisely metered via a metering conveyor belt before being transported to the reaction vessel, ensuring precise control, reducing proportioning errors, and contributing to improved absorbent preparation quality. The liquid conveying mechanism uses an elevator to lift containers containing liquid solvents to the top of the reaction vessel, enabling rapid feeding, improving liquid solvent conveying efficiency, reducing feeding time, and increasing overall production efficiency. Then, a tilter automates the pouring operation into the reaction vessel, effectively saving manpower. Furthermore, by controlling the tilting angle and pouring time of the tilter, the amount of liquid solvent fed can be flexibly controlled, achieving precise feeding and improving absorbent preparation quality.

[0019] Furthermore, the top of the reaction vessel is provided with a limiting mechanism for limiting the liquid container. The limiting mechanism includes two limiting rods fixed to the top of the reaction vessel. The two limiting rods form a figure-eight-shaped limiting channel, and the smaller end of the limiting channel faces the reaction vessel.

[0020] Beneficial effects: In the traditional process of preparing absorbents, pouring liquid containers often requires manual operation. To free up operators, a liquid conveying mechanism was designed to automatically lift and pour the liquid. However, the containers holding liquid solvents are usually barrel-shaped, which are prone to rolling during pouring, resulting in displacement deviation and spillage. Therefore, this solution incorporates a limiting mechanism. When the container is poured by the pourer, it is positioned within the limiting channel. The limiting mechanism effectively limits the container, preventing it from rolling and ensuring that the liquid solvent is accurately poured into the reaction vessel, avoiding waste of raw materials.

[0021] Secondly, the limiting mechanism provides clear operating guidance for operators. When the elevator lifts the liquid container, the operator does not need to manually adjust the container position to align with the reaction container. The operator only needs to place the container roughly at the beginning of the limiting channel, and the subsequent container can automatically and accurately reach the target position under the guidance of the limiting channel. This simplifies the operation process, reduces the difficulty of operation, and also reduces the safety risks faced by operators due to proximity to dangerous areas such as reaction containers during operation, thus improving the convenience and safety of operation.

[0022] Furthermore, the tilter is tilted upwards towards the reaction vessel to form an inclined plane, and the angle between the inclined plane and the central axis of the reaction vessel is 15°-30°.

[0023] Beneficial effects: The inclined surface of the tilter acts as a guide. When the upper part of the liquid container comes into contact with the inclined surface, the liquid container tilts until it is poured into the limiting channel formed by the limiting rod. The liquid in the liquid container enters the reaction container through the inlet of the reaction container. No manual intervention is required for feeding, reducing labor intensity.

[0024] Secondly, the angle between the inclined plane and the central axis of the reaction vessel is 15°-30°, allowing the liquid-filled container to gradually pour the liquid at an appropriate tilt angle after being raised and contacting the inclined plane. This angle prevents the container from tilting too quickly, causing liquid splashing or uncontrolled pouring, while also preventing the liquid from flowing out too slowly due to an excessively small tilt angle, thus affecting the feeding efficiency. This stable pouring method allows for precise control of the amount of liquid added each time, ensuring accurate addition of raw materials during the reaction process and contributing to improved product quality stability and consistency.

[0025] Furthermore, the water supply mechanism includes a main cooling pipe, a main heating pipe, a water supply pipe, a heat exchange pipe, and a return pipe. Each of the water supply pipe, heat exchange pipe, and return pipe includes a branch cooling pipe and a branch heating pipe. The heat exchange component includes a heat exchange coil. The input ends of the branch cooling pipes of the water supply pipe and the heat exchange pipe are connected to the main cooling pipe. The input ends of the branch heating pipes of the water supply pipe and the heat exchange pipe are connected to the main heating pipe. The output end of the water supply pipe is connected to the inlet of the reaction vessel. The output end of the heat exchange pipe is connected to the input end of the heat exchange coil. The output end of the heat exchange coil is connected to the input end of the return pipe. The output ends of the branch cooling pipes and branch heating pipes of the return pipe are connected to the input ends of the branch cooling pipes and branch heating pipes of the heat exchange pipe.

[0026] Beneficial Effects: Considering both cost and overall configuration process, and given the need for water supply within the reaction vessel and heat exchange requirements, water's high specific heat capacity makes it a highly stable heat exchange medium. This design incorporates a water supply system, working in conjunction with heat exchange coils to achieve closed-loop water circulation heat exchange. The water supply pipe supplies water to the reaction vessel, primarily for pre-filling the preparation water volume before preparation. During preparation, water is added according to the reagent density for adjustment, and the reaction vessel temperature can also be regulated simultaneously. The heat exchange coils are mainly used for temperature control, facilitating heat exchange through the heat exchange coils located at the bottom of the reaction vessel. Higher water volumes increase the temperature, while lower volumes decrease it. The reflux pipe is used for circulating heat exchange, improving the economic efficiency of heat exchange. The water supply system, while meeting water supply requirements, works in conjunction with the heat exchange coils to achieve stable and efficient heat exchange, effectively ensuring the chemical reaction conditions during absorbent preparation, improving reaction efficiency and product purity, thereby enhancing the quality of absorbent preparation.

[0027] This solution also provides a technical solution: an automated continuous production system, including the above-mentioned preparation device, and further including a monitoring mechanism and a centralized control box. The monitoring mechanism is used to monitor the internal parameters of the reaction vessel, and the centralized control box is used to receive the data signals from the monitoring mechanism and control the temperature, stirring rate and reagent density in the preparation device according to the data signals.

[0028] The beneficial effects of this plan are:

[0029] 1. Ensure absorbent quality: This solution uses a monitoring agency to monitor reagent density in real time, and a centralized control box can control the operation of the solid and liquid conveying mechanisms, precisely adjust the amount of raw materials added, and ensure the accuracy of the absorbent formulation ratio, thereby improving the preparation quality and stability of the absorbent and ensuring its good performance in applications such as carbon dioxide capture.

[0030] 2. Optimized Production Process: The centralized control box automatically controls the operation of each mechanism based on data from the monitoring agency, eliminating the need for frequent manual intervention, reducing manual operation time and errors, and improving production efficiency. Simultaneously, automated control makes the production process more continuous and stable, avoiding production interruptions or fluctuations caused by untimely or inaccurate manual operation, thus facilitating the continuous production of organic amine absorbents and increasing overall output.

[0031] 3. Enhanced production safety: The monitoring agency monitors key parameters inside the reaction vessel in real time. Once an abnormality occurs, such as excessively high temperature or abnormal liquid level, the centralized control box can immediately issue an alarm and take corresponding measures to adjust or shut down the machine, avoiding safety accidents caused by abnormal parameters, reducing safety risks in the production process, and ensuring the safety of operators and equipment.

[0032] Furthermore, the monitoring mechanism includes a densitometer, a level gauge, and a flow meter. The level gauge is installed on the top wall of the reaction vessel. The densitometer includes a first densitometer and a second densitometer. The first densitometer is installed inside the reaction vessel, and the second densitometer is installed near the outlet of the reaction vessel. The flow meter is installed at the outlet of the water supply pipe.

[0033] To monitor the liquid level and water input within the reaction vessel and ensure safe and stable production, a level gauge and a flow meter were installed. The level gauge, installed on the top wall of the reaction vessel, can monitor the liquid level in real time, effectively preventing material overflow due to excessively high liquid levels during the reaction, thus avoiding waste and safety hazards. It also prevents the reaction vessel from dry-burning due to excessively low liquid levels, protecting the equipment. The flow meter, installed at the output end of the water supply pipe, can accurately measure the amount of water supplied to the reaction vessel, ensuring the reaction proceeds in a suitable humidity environment, improving reaction stability and product quality. It also prevents reaction runaway or product quality degradation due to excessive or insufficient water supply.

[0034] To ensure accurate density data, a first density meter and a second density meter are installed to monitor the solvent density data inside the reaction vessel and at the outlet, respectively. Comprehensive calculations are performed to prevent data errors and ensure that the density of the output absorbent product meets strict quality standards, avoiding product performance instability due to density fluctuations.

[0035] Furthermore, the main cooling pipe, main heating pipe, water supply pipe, heat exchange pipe, and return pipe are all equipped with corresponding valves. All valves are electric valves, and the opening and closing and opening degree of the valves are controlled by a centralized control box.

[0036] To further enhance automation, all valves are electric valves, and a centralized control box receives all detection data to control the opening and closing of the corresponding valves and the degree of opening, truly realizing fully automated production. Attached Figure Description

[0041] Example 1 is basically as shown in the attached document. Figure 1-2 As shown:

[0042] As attached Figure 1 As shown, an apparatus for preparing absorbent formulations includes a reaction mechanism, a temperature control mechanism, a water supply mechanism 4, and a conveying mechanism; the reaction mechanism includes a reaction vessel and a stirring structure disposed on the top of the reaction vessel, the reaction vessel being a reaction kettle 1, and the stirring structure being a prior art stirrer 101, the blades of the stirrer 101 being a spiral structure; the top of the reaction kettle 1 has two inlets, which are used for feeding liquid solvent and solid raw materials, respectively.

[0043] The conveying mechanism includes a solid conveying mechanism for transporting solid raw materials and a liquid conveying mechanism for transporting liquid solvents. The solid conveying mechanism includes a metering conveyor belt 3, and the liquid conveying mechanism includes an elevator 2 and a tilter 202 mounted on top of the elevator 2. The tilter 202 is inclined upwards towards the reactor 1, forming a ramp with an angle of 15°-30° between the ramp and the central axis of the reactor 1. Solid materials are precisely metered by the metering conveyor belt 3 before being transported to the reactor 1, ensuring precise control. The liquid conveying mechanism lifts the solution tank 201 to the top of the reactor 1 via the elevator 2, and then the tilter 202 pours the liquid solvent into the reaction vessel, automating the pouring operation. This setup enables simultaneous and precise feeding of both solid and liquid materials, reducing feeding time, improving overall production efficiency, and minimizing proportioning errors, thus contributing to improved absorbent preparation quality.

[0044] Furthermore, to prevent the solution tank 201 from easily rolling and shifting during the pouring process, causing liquid spillage, a limiting mechanism is provided on the top of the reactor 1 near the elevator 2. This limiting mechanism is a tank limiter 102, which includes two limiting rods connected and fixed to the top of the reactor 1. The two limiting rods form a figure-eight-shaped limiting channel, with the smaller end of the limiting channel facing the reaction vessel. When the solution tank 201 containing the liquid solvent is lifted to the top of the elevator 2, the solution tank 201 tilts between the two limiting rods, aligning the opening of the solution tank 201 with the inlet of the reactor 1, preventing material waste. Furthermore, the elevator 2, in conjunction with the tank limiter 102, achieves automatic lifting and pouring, eliminating the need for manual pouring and reducing the labor intensity of workers.

[0045] The temperature control mechanism includes temperature sensors 104 and heat exchange coils 5, with the heat exchange coils 5 positioned at the bottom of the reactor 1. Three temperature sensors 104 are located inside the reactor 1, arranged vertically to uniformly measure the temperature of different reagent liquid layers, reducing measurement errors. The heat exchange coils 5, positioned at the bottom of the reactor 1, facilitate heat exchange between reagent liquid layers, improving heating efficiency. The reactor 1 has an outlet connected to a discharge pipe, a vent valve 109, and a discharge valve 108. The vent valve 109 is used to vent the internal solution during reactor 1 cleaning, and the discharge valve 108 is used to discharge the finished reagent.

[0046] like Figure 2As shown, the outlet of the water supply mechanism is located above the inlet of the reaction vessel. The water supply mechanism 4 includes a main cold water pipe 401, a main hot water pipe 402, two main valves, a water supply pipe, a heat exchange pipe, and a return pipe. The two main valves are respectively installed on the inlet pipes of the main cold water pipe 401 and the main hot water pipe 402. Both the water supply pipe and the heat exchange pipe include branch cold water pipes, branch hot water pipes, and four branch valves. The inlet of the branch cold water pipes of both the water supply pipe and the heat exchange pipe is connected to... The output ends of the main cold water pipe 401 and the input ends of the branch hot water pipes of the makeup water pipe and the heat exchange pipe are both connected to the output end of the main hot water pipe 402. The branch cold water pipe and branch hot water pipe of the makeup water pipe are respectively the makeup water cold pipe 404 and the makeup water heat pipe 403. The output ends of the makeup water cold pipe 404 and the makeup water heat pipe 403 are both connected to the input end of the reactor 1. A water supply cold valve 410 is installed on the makeup water cold pipe 404, and a water supply heat valve 409 is installed on the makeup water heat pipe 403. The branch cold water pipe and branch hot water pipe of the heat exchange pipe are respectively the heat exchange cold pipe 406 and the heat exchange heat pipe 405. The output ends of the heat exchange cold pipe 406 and the heat exchange heat pipe 405 are connected to the input end of the heat exchange coil 5. A heat exchange cold valve 412 is installed on the heat exchange cold pipe 406, and a heat exchange heat valve 411 is installed on the heat exchange heat pipe 405. The reflux pipe includes a reflux cold pipe 408, a reflux hot pipe 407, a reflux cold valve 414, and a reflux hot valve 413. The output end of the heat exchange coil 5 is connected to the input end of the reflux cold water pipe and the reflux hot water pipe. The output end of the reflux cold pipe 408 is connected to the input end of the heat exchange cold pipe 406, and the output end of the reflux hot pipe 407 is connected to the input end of the heat exchange hot pipe 405.

[0047] This solution also provides an automated continuous production system, including the above-mentioned preparation device for absorbent formulation, and further including a monitoring mechanism and a centralized control box 6. The monitoring mechanism is used to monitor the internal parameters of the reaction vessel, and the centralized control box 6 is used to receive data signals from the monitoring mechanism and control the temperature, stirring rate and reagent density in the preparation device according to the data signals. Preferably, the centralized control box can also be remotely controlled by a DCS system, which improves the efficiency of automated production while reducing on-site personnel involvement and reducing the safety risks of personnel operation.

[0048] The monitoring system includes a first density meter 105, a second density meter 106, a flow meter 107, and a level gauge. The level gauge is installed on the top wall of the reactor 1 to monitor the liquid level in real time, effectively preventing excessive liquid level during the reaction process from causing material overflow, waste, and safety hazards. The first density meter 105 is installed inside the reactor 1, and the second density meter 106 is installed near the outlet of the reactor 1 to ensure that the density of the output absorbent product meets strict quality standards and avoids unstable product performance due to density fluctuations. The flow meter 107 is installed at the output end of the water supply pipe to monitor the water volume in the reaction vessel in real time and accurately replenish water.

[0049] In this embodiment, all valves are electric valves. The centralized control box 6 receives and processes the data signals from the temperature sensor 104, the first density meter 105, the second density meter 106, and the flow meter 107. Then, it outputs data signals to control the opening degree of each valve to control the temperature, adjust the reagent density, adjust the stirring rate, and adjust the working status of each mechanism of the production system in real time to achieve automated control.

[0050] After implementing this solution, the various institutions worked together to reduce labor intensity and improve efficiency through the automation system. This solved the problems of insufficient quality and output in the preparation of existing absorbents. The amount of manual operation was reduced by 80%, energy consumption was saved by 5%, the overall safety and operational reliability were improved, and the quality of the prepared reagents was effectively improved, thus achieving cost reduction and efficiency improvement.

[0051] The specific implementation method is as follows:

[0052] Select the desired reagent formula, and set the required quantities of each material, initial water volume, water temperature, and stirring rate according to the formula using the centralized control box 6. After setting, the reagent preparation begins, and the production system enters the reagent preparation working state. First, control the opening and closing of the cold water supply valve and the hot water supply valve according to the required temperature for reagent preparation to control the appropriate water temperature. Monitor the water volume input into the reaction vessel 1 using the flow meter 107. Once the required water volume is reached (satisfying the liquid level required to start the stirrer 101), the flow meter 107 sends a signal to the centralized control box 6. The centralized control box 6 then controls the closure of the cold water supply valve and the hot water supply valve, and controls the start of the stirrer 101. The stirrer 101 begins stirring at the set rate.

[0053] Based on the set temperature of reactor 1 and the current water temperature inside reactor 1, the opening degrees of heat exchange hot valve 411 and heat exchange cold valve 412 are controlled to adjust the water temperature entering the heat exchange coil 5. Then, the elevator 2 lifts the solution tank 201 upwards. The solution tank 201 contacts the tilter 202 and is stopped by the tank limiter 102. The elevator 2 continues to lift so that the solution in the solution tank 201 is evenly injected into reactor 1. After tilting, the solution tank 201 descends with the elevator 2. The metering conveyor belt 3 is set according to the... A predetermined amount of solid material is transferred into reactor 1. After all the materials required for reagent preparation have entered reactor 1, the level gauge measures the liquid level and sends a signal to the central control box 6. The central control box 6 controls the opening and closing of the cold water supply valve and the hot water supply valve, controls the appropriate water temperature, and monitors the water volume entering reactor 1 through the flow meter 107. Once the required water volume is reached (meeting the reagent ratio), the flow meter 107 sends a signal to the central control box 6, and the central control box 6 controls the closure of the cold water supply valve and the hot water supply valve.

[0054] The centralized control box 6 controls the stirrer 101 to the required stirring and mixing speed. It judges the mixing status of the reagent based on the difference between the monitoring data of the first densitometer 105 and the second densitometer 106. When the difference remains basically unchanged, that is, when the mixture is uniform, it adjusts the water supply or the delivery of solid materials according to the density to adjust the density of the reagent until the overall density value meets the requirements. During this process, the temperature sensor 104 collects signals in real time and sends them to the centralized control box 6. The centralized control box 6 controls the opening and closing of the heat exchange hot valve 411 and the heat exchange cold valve 412 in real time to control the water temperature input to the heat exchange coil 5, so that the temperature in the reactor 1 remains stable. The water after entering the heat exchange coil 5 flows back to the heat exchange hot pipe 405 and the heat exchange cold pipe 406 through the return hot pipe 407 and the return cold pipe 408 to achieve circulating heat exchange.

[0055] The central control box 6 controls the opening of the unloading valve 108 at the bottom of the reactor 1 to release the finished reagent for packaging. After unloading, the vent valve 109 is opened to clean and release the remaining waste liquid. After inspection, a new round of production begins. This cycle is repeated to achieve efficient and automated production.
