Description

Technical Field

[0001] This utility model relates to the field of chemical equipment, and in particular to an automated interlocking control fluorination device that improves safety. Background Technology

[0002] In existing technologies, the fluorochemical section of the flunixin production process largely adopts a semi-automated mode. In this mode, the reaction vessel is under high pressure and high temperature, increasing the risks to personnel. Specifically, firstly, the current control of this section mainly relies on manual valves, and the pressure and temperature detection are not interlocked for safety. Therefore, most operations such as adding materials and cooling down require manual intervention. During the material addition process, workers are close to the feed valve, and if a leak occurs due to an accident, workers may not have time to escape, potentially causing injury or death. Secondly, in case of over-temperature or over-pressure, cooling and depressurization can only be done manually, which introduces a certain degree of lag. Utility Model Content

[0003] Therefore, there is a need to provide an automated interlocking control fluorination device with improved safety to solve this problem.

[0004] To achieve the above objectives, this utility model provides an automated interlocking control fluorination device with improved safety, including a reaction vessel and a control unit. The reaction vessel is equipped with a detection unit, a motor, and a stirrer that are electrically connected to the control unit. The detection unit is used to detect the pressure and temperature inside the reaction vessel, and the motor is used to drive the stirrer located inside the reaction vessel to rotate.

[0005] The inner cavity of the reactor is connected to different supply or receiving ends through the following components: first feed pipe, first feed valve, second feed pipe, second feed valve, air inlet pipe, air inlet valve, tail gas pipe, tail gas valve, vacuum pipe, vacuum valve, vent pipe, vent valve, discharge pipe, and discharge valve.

[0006] The reactor is equipped with a jacket on its outer side, and the inner cavity of the jacket is connected to different supply or receiving ends through the following components: refrigerant inlet pipe, refrigerant inlet valve, heat inlet pipe, heat inlet valve, refrigerant outlet pipe, refrigerant outlet valve, heat outlet pipe, heat outlet valve, compression pipe and compression valve.

[0007] The refrigerant inlet valve, heat medium inlet valve, refrigerant outlet valve, heat medium outlet valve, and vent valve are all electrically connected to the control unit.

[0008] Furthermore, the detection unit includes a temperature transmitter and a pressure transmitter.

[0009] Furthermore, it also includes a current monitoring instrument electrically connected to the control unit, which is used to detect the operating status of the stirrer.

[0010] Furthermore, the first feed pipe is also equipped with a feed regulating valve, which is electrically connected to the control unit.

[0011] Furthermore, a refrigerant regulating valve is also provided on the refrigerant inlet pipe, and the refrigerant regulating valve is electrically connected to the control unit.

[0012] Furthermore, a heat medium regulating valve is also provided on the heat medium inlet pipe, and the heat medium regulating valve is electrically connected to the control unit.

[0013] Furthermore, the first feed valve, the second feed valve, the air inlet valve, the exhaust valve, the vacuum valve, the vent valve, the discharge valve, the refrigerant inlet valve, the hot medium inlet valve, the refrigerant outlet valve, and the hot medium outlet valve are all on / off type electrically controlled valves.

[0014] Furthermore, the feed regulating valve, refrigerant regulating valve, and heat regulating valve are all regulating type electrically controlled valves.

[0015] Unlike existing technologies, the above-mentioned technical solution automates the operation by installing a detection unit on the reactor to monitor the internal temperature and pressure. This unit, in conjunction with a control unit, closes the inlet and outlet valves of the hot medium and opens the inlet and outlet valves of the cold medium when the temperature is too high. Conversely, it closes the inlet and outlet valves of the hot medium and opens the inlet, outlet valves of the cold medium and the relief valve when the pressure is too high. This eliminates the need for manual valve control and improves operator safety. Attached Figure Description

[0032] Please see Figures 1 to 5This embodiment provides an automated interlocking control fluorination device with improved safety, including a reaction vessel 10 and a control unit. The reaction vessel 10 is equipped with a detection unit, a motor 11 and a stirrer 12 that are electrically connected to the control unit. The detection unit is used to detect the pressure and temperature inside the reaction vessel 10, and the motor 11 is used to drive the stirrer 12 located inside the reaction vessel 10 to rotate.

[0033] The reactor 10 provides a sealed space for the reaction. It has an internal cavity into which reactants are introduced into the reactor 10 via different pipelines in a predetermined ratio. Together with components such as the stirrer 12, the chemical reaction is achieved. In the fluorination reaction, the reactor needs to come into contact with highly corrosive substances such as hydrogen fluoride. Therefore, the reactor 10 can be made of corrosion-resistant alloys, nickel and nickel-based alloys, or steel lined with polytetrafluoroethylene. Stainless steel is commonly used. In the fluorination reaction, the interior of reactor 10 is under high temperature and pressure. The wall thickness of reactor 10 should be adjusted according to the reaction conditions. First, the internal pressure must be determined. The calculation of the wall thickness of reactor 10 first requires determining the internal pressure that reactor 10 will bear, which is determined by the properties of the reactants and the operating conditions. Second, based on the properties of the reactants and the operating conditions, a suitable material should be selected, such as stainless steel or carbon steel. Static stress, which is the maximum inner diameter stress that the material can withstand, can be calculated using the formula σ=(P*D) / (2*t), where σ is the static stress, P is the internal pressure, D is the inner diameter (or outer diameter) of reactor 10, and t is the wall thickness. Based on the calculated static stress and the yield strength of the selected material, a suitable wall thickness should be selected to ensure that the wall is thick enough to withstand the internal pressure. Based on the simple calculation method, the influence of factors such as corrosion and wear on the wall thickness should be further considered. Since reactor 10 needs to come into contact with corrosive materials, a corrosion allowance of 1-3mm can be added to extend the service life of the equipment.

[0034] The control unit receives electrical signals from the detection unit and analyzes the signals in real time. Based on preset critical parameters, it controls the valve to open or close. This invention does not involve software improvements; the control unit can use existing technology to control the valve opening and closing. The control unit can employ one of the following: a PID controller, a common feedback controller used for precise control of parameters such as temperature and pressure in the reactor 10. The PID controller achieves precise control of process variables within the reactor 10 by adjusting the proportional (P), integral (I), and derivative (D) parameters. For example, in temperature control, the PID controller can adjust the flow rate of the heating or cooling medium based on the deviation between the actual temperature and the set temperature to control the temperature of the reactor 10. A grey predictive PID controller, which combines grey prediction technology, is suitable for controlled objects with large time lags and features small overshoot and strong anti-interference capabilities. The prediction steps of the grey predictor are determined through simulation to optimize the control effect. A valve opening limit controller, which can adjust the upper and lower limits of the valve opening to adapt to different reaction stages and requirements. It can dynamically adjust the valve opening based on the heating rate, valve opening, and the relationship between the detected temperature value and the set value, avoiding overshoot and meeting the reaction requirements at different stages. A feedforward controller can predict and compensate for the impact of external disturbances on the process, such as adjusting the valve opening in advance to maintain pressure stability within the reactor 10 by monitoring pressure changes at the heating medium outlet. A fuzzy-PID controller combines fuzzy logic and PID control, capable of handling complex, nonlinear, or time-varying systems that are difficult to handle with traditional PID controllers. A PLC control system, or programmable logic controller (PLC), can control various valves in the reactor 10. By receiving signals from sensors such as temperature and pressure, and adjusting the valve opening according to preset control logic, it achieves automated control of the reactor 10. A TCU (Temperature Control Unit) is a dedicated temperature control unit that can be installed near the reactor 10 to precisely control and regulate the temperature within the reactor 10, ensuring the stability and safety of the reaction process. It should be noted that the aforementioned controllers can be used individually or in combination to achieve precise control of different valves.

[0035] The detection unit is used to monitor information inside the reactor 10 and the multiple pipelines connected to it. Specifically, it includes a temperature transmitter 13 and a pressure transmitter 14.

[0036] The temperature transmitter 13 is an instrument that converts temperature variables into a standardized, transmittable output signal, primarily used for measuring the internal temperature of the reactor 10. It typically consists of two parts: a sensor and a signal converter. Its structure is as follows: Sensor: The sensor is the core component of the temperature transmitter 13, primarily a thermocouple or a resistance temperature detector (RTD). A thermocouple measures temperature by utilizing the thermoelectric potential generated when two different metals change temperature, while an RTD is based on the characteristic that the resistance of a metal changes with temperature. Signal Converter: The signal converter includes a measurement unit, signal processing and conversion unit, responsible for converting the temperature signal detected by the sensor into a standardized electrical signal output. Some transmitters also include a display unit and fieldbus functionality. Measurement Circuit: The measurement circuit converts the resistance change of the RTD element into a voltage or current signal, typically using a bridge circuit or a Wheatstone bridge circuit. Output Circuit: The output circuit amplifies, filters, and converts the signal from the measurement circuit, ultimately outputting a standard current signal (e.g., 4-20mA) or voltage signal (e.g., 0-10V). Its working principle is as follows: The temperature transmitter 13 acquires temperature information through the sensor. For the RTD temperature transmitter 13, it converts temperature signals into electrical signals based on the characteristic that the resistance of a metal changes with temperature. The acquired signals are usually very weak and need to be amplified. Since the relationship between the RTD and temperature may not be linear, specific circuits or algorithms are needed to linearize the signal to ensure that the output signal is proportional to the temperature. After amplification and linearization, the signal needs to be converted into a standard current signal (e.g., 4-20mA) for long-distance transmission and compatibility with other systems. Isolation protection measures are usually added before signal output to prevent external interference from affecting signal accuracy and to protect internal circuitry from damage. The temperature transmitter 13 detects temperature changes through its sensor, converts these changes into electrical signals, processes and converts them through a signal converter, and finally outputs a standardized electrical signal. Specific models include the TA1004, DATEXELRTD temperature transmitter 13DAT2065, and temperature transmitters 13 with similar or identical functions.

[0037] The pressure transmitter 14 is mainly used to measure and convert pressure signals. It typically consists of the following parts: a pressure sensing element sensor, which is the core component of the pressure transmitter 14 and is responsible for sensing pressure changes in the measured medium. Common sensing elements include piezoresistive, capacitive, and piezoelectric types. A module circuit, which amplifies, filters, and linearizes the weak electrical signal output from the sensor to convert it into a standard electrical signal output. A display head, some pressure transmitters 14 are equipped with a display head for displaying pressure readings on-site. A housing and process connectors, the housing protecting the internal components and providing protection, corrosion resistance, and explosion-proof functions, while the process connectors connect the transmitter to the measured medium. The working principle of the pressure transmitter 14 is based on the following steps: pressure sensing, when the pressure of the measured medium (gas or liquid) acts on the pressure sensing element sensor, the sensitive element inside the sensor (such as a ceramic diaphragm or diffused silicon sensitive element) undergoes a slight deformation. The deformation is sensed by the internal circuitry of the sensor (such as a Wheatstone bridge) and converted into a corresponding electrical signal. The sensor output signal is typically very weak and needs to be amplified. The amplified signal undergoes further linear correction and temperature compensation to ensure a linear relationship between the output signal and the pressure of the measured medium, and to prevent interference from temperature changes. The processed electrical signal is then converted into a standard output signal, such as 4–20mA DC or 1–5VDC. These standard signals can be received and processed by various secondary instruments (such as indicators, alarms, recorders, and regulators) to monitor the pressure inside the reactor 10.

[0038] The motor 11 is the power source for the agitator 12. It converts high-speed rotation into low-speed rotation suitable for agitation through a reducer. Various types of motors 11 are available, including ordinary asynchronous motors, variable frequency speed-regulating motors, explosion-proof motors, permanent magnet synchronous motors, and servo motors. The selection of the motor 11 depends on the viscosity, speed, and capacity of the material to ensure efficient and stable operation of the reactor 10 under different process conditions. The agitator 12 can be a turbine agitator 12, which resembles the open impeller of a centrifugal pump, with high speed and comprehensive mixing capability; or a paddle agitator 12, composed of two or three blades, with a simple structure and economical application; or an anchor agitator 12, which is larger, operates at a lower speed, and has a smaller gap with the reactor wall during rotation, preventing material from charring on the wall and improving heat exchange efficiency.

[0039] The inner cavity of the reactor 10 is connected to different supply or receiving ends via the following components: a first feed pipe 21, a first feed valve 211, a second feed pipe 22, a second feed valve 221, an air inlet pipe 23, an air inlet valve 231, a tail gas pipe 24, a tail gas valve 241, a vacuum pipe 25, a vacuum valve 251, a vent pipe 26, a vent valve 264, a discharge pipe 27, and a discharge valve 271. The first feed pipe 21 and the second feed pipe 22 are both used to input reaction raw materials, and are controlled by the first feed valve 211 and the second feed valve 221 respectively. The air inlet pipe 23 and the air inlet valve 231 are used to input nitrogen gas. By inputting nitrogen gas into the fluorination reactor 10, the air inside the reactor 10 can be effectively discharged, forming an inert environment, thereby protecting the materials inside the reactor 10 from oxidation and preventing air from entering and causing an explosion. The vacuum tube 25 and vacuum valve 251 are used to extract air from the inside of the reactor 10 to achieve a predetermined low-pressure environment. This lowers the boiling point of the reactants, accelerates the reaction rate, and improves the reaction effect, while also enhancing reaction safety. The vent pipe 26 and vent valve 264 ensure the safe release of pressure from the reactor 10 in case of overpressure or other emergencies, preventing accidents and protecting personnel and the environment. When the internal pressure exceeds a set safety value, pressure is released through the vent pipe 26 to prevent overpressure accidents caused by improper operation or equipment malfunction. The discharge pipe 27 and discharge valve 271 are used to transport the reacted materials to the downstream end.

[0040] The reactor 10 is provided with a jacket 15 on its outer side. The inner cavity of the jacket 15 is connected to different supply or receiving ends through the following components: refrigerant inlet pipe 28, refrigerant inlet valve 281, heat medium inlet pipe 29, heat medium inlet valve 291, refrigerant outlet pipe 30, refrigerant outlet valve 301, heat medium outlet pipe 31, heat medium outlet valve 311, compression pipe 32, and compression valve 321. The jacket 15 is a double-layer structure set outside the cylinder of the reactor 10. A sealed space is formed between the jacket 15 and the cylinder of the reactor 10. A heat transfer fluid, such as steam, hot water, or a cooling medium, can be introduced into this space to heat or cool the material inside the reactor 10, thereby maintaining the temperature of the material within a specified range. The jacket 15 can be filled with refrigerant by cooperating with the refrigerant inlet pipe 28, refrigerant inlet valve 281, refrigerant outlet pipe 30, and refrigerant outlet valve 301, thereby cooling the reactor 10. Similarly, the jacket 15 can be filled with refrigerant by cooperating with the heat medium inlet pipe 29, heat medium inlet valve 291, heat medium outlet pipe 31, and heat medium outlet valve 311, thereby heating the reactor 10. The compression pipe 32 and compression valve 321 are used to input compressed air into the jacket and to vent air, refrigerant, or heat medium.

[0041] The refrigerant inlet valve 281, the heat medium inlet valve 291, the refrigerant outlet valve 301, the heat medium outlet valve 311, and the vent valve 264 are all electrically connected to the control unit.

[0042] This novel invention features a detection unit on the reactor 10 for monitoring the internal temperature and pressure. In conjunction with a control unit, when the temperature is too high, the control unit closes the heat transfer inlet valve 291 and the heat transfer outlet valve 311 while simultaneously opening the refrigerant inlet valve 281 and the refrigerant outlet valve 301. When the pressure is too high, the control unit closes the heat transfer inlet valve 291 and the heat transfer outlet valve 311 while simultaneously opening the refrigerant inlet valve 281, the refrigerant outlet valve 301, and the relief valve 264. This automated operation eliminates the need for manual valve control, improving operator safety.

[0043] In some embodiments, a current monitoring instrument 16 electrically connected to the control unit is also included. The current monitoring instrument 16 is used to detect the operating status of the stirrer 12. The input terminal of the current monitoring instrument 16 is connected to the power line of the motor 11 via a current transformer (CT). The current transformer converts the large current of the motor 11 into a small current that the instrument can measure. During the operation of the stirrer 12, the current reading is continuously monitored. Any abnormal current changes may indicate a problem with the stirrer 12, such as overload, motor 11 failure, or mechanical failure. In the event of an abnormality in the stirrer 12, the first feed valve 211 or the second feed valve 221 is interlocked off by the control unit, and cooling measures are implemented only if necessary to improve safety.

[0044] In some embodiments, a feed regulating valve 212 is also provided on the first feed pipe 21, and the feed regulating valve is electrically connected to the control unit. Alternatively, a refrigerant regulating valve 282 is also provided on the refrigerant inlet pipe 28, and the refrigerant regulating valve is electrically connected to the control unit. Or, a heat medium regulating valve 292 is also provided on the heat medium inlet pipe 29, and the heat medium regulating valve is electrically connected to the control unit. By providing a feed regulating valve in the first feed pipe 21 of the reactor 10, the feed rate and feed volume of the raw materials can be precisely controlled to ensure that the chemical reaction proceeds under predetermined conditions. The feed regulating valve can adjust the feed flow rate by changing the valve opening, thereby indirectly adjusting the feed volume of the raw materials. This control is crucial for maintaining the liquid level of the materials in the reactor 10, ensuring sufficient reaction of the reactants, and preventing excessive pressure in the reactor 10 due to excessive material. Furthermore, the regulating valve also helps maintain stable pressure within the reactor 10, ensuring that the chemical reaction proceeds under predetermined pressure conditions, improving safety and efficiency. The same principle applies to refrigerant regulating valves as to heat regulating valves, so it will not be elaborated here.

[0045] In some embodiments, the first feed valve 211, the second feed valve 221, the air inlet valve 231, the exhaust valve 241, the vacuum valve 251, the vent valve 264, the discharge valve 271, the refrigerant inlet valve 281, the hot medium inlet valve 291, the refrigerant outlet valve 301, and the hot medium outlet valve 311 are all on / off type electrically controlled valves. The working principle of the on / off type electrically controlled valve is mainly based on the principle of electromagnetic induction, and its core components include an electromagnetic coil and a valve body. When the electromagnetic coil is energized, the generated magnetic field attracts the valve core to move, thereby changing the valve's on / off state; when the power is off, the electromagnetic force disappears, and the valve core is usually returned to its original position by a spring or other reset device, realizing the valve closure and achieving remote control and automated control.

[0046] In some embodiments, the feed regulating valve, refrigerant regulating valve, and heat medium regulating valve are all regulating electrically controlled valves. They control the flow rate, temperature, pressure, and other process parameters of the pipeline medium by receiving signals from the control unit to change the cross-sectional area between the valve core and valve seat. Specifically, when the control unit outputs a signal to the actuator of the regulating valve, the actuator converts this signal into mechanical displacement. This displacement may be achieved by rotating a valve motor, which drives a connecting rod or gear to adjust the valve position. As the valve core position changes, the fluid flow rate changes accordingly, thereby achieving the purpose of regulating process parameters. Electrically controlled valves are usually equipped with a feedback mechanism to monitor the actual valve opening and feed the data back to the control system. If the actual opening does not match the target opening, the system will automatically send a new command to continue adjusting the valve position until the fluid parameters reach the set value. Common types of regulating electrically controlled valves include electric regulating valves, pneumatic regulating valves, and self-operated regulating valves.

[0047] It should be noted that this invention does not limit the specific locations on the reactor for connecting to various pipelines. Figure 4 and Figure 5 The examples shown are merely illustrative of the reactor's interface being located at the top, side, or bottom of the reactor jacket, and are not representative of the same embodiment.

[0048] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
