Q1:What are the common types of reactors, and what reactions are they suitable for?
1. Enamel reactor: The reactor body is made of glass glaze containing high silicon dioxide coated on the metal surface and sintered at high temperature. It is suitable for reactions with certain corrosive materials, such as common acid-base catalytic reactions, such as esterification reactions. Its glass glaze coating can effectively resist the erosion of general acids and alkalis, prevent the metal reactor body from being corroded, and the smooth inner wall facilitates material cleaning and discharge after the reaction.
2. Stainless steel reactor: Made of stainless steel, it has good corrosion resistance, high temperature resistance and strength. It is suitable for various types of reactions, especially in industries with high hygiene requirements such as food, pharmaceuticals, and fine chemicals. For example, in the drug synthesis reaction in the pharmaceutical industry, stainless steel reactors can meet strict hygiene standards and avoid material contamination. At the same time, its good thermal conductivity is conducive to temperature control during the reaction process.
3. Carbon steel reactor: The cost is relatively low and it is suitable for reactions that do not require high corrosion resistance, such as some polymerization reactions with high temperature and high pressure but weak material corrosiveness. In some industrial production, if the material has little effect on metal corrosion, the use of carbon steel reactors can effectively reduce equipment procurement costs and improve economic benefits.
4. Glass-lined reactor: It combines the advantages of enamel and glass and has excellent chemical stability and electrical insulation. It is often used in some fine chemical reactions that have strict requirements on the reaction environment and require precise control of reaction conditions, such as some organic synthesis reactions. It can provide a stable environment for the reaction and ensure the smooth progress of the reaction.
Q2:How to choose the right reactor material according to the reaction conditions?
1. Temperature factor: If the reaction temperature is low, reactors of general materials can meet the requirements. But when the reaction temperature is high, such as high temperature and high pressure reactions, it is necessary to choose materials with good high temperature resistance. For example, stainless steel can withstand higher temperatures and is suitable for medium and high temperature reactions; while enamel reactors may have problems such as glaze shedding at high temperatures, and the use temperature is relatively limited.
2. Pressure factor: For high-pressure reactions, the reactor material needs to have sufficient strength to withstand pressure. Carbon steel and stainless steel can meet the requirements of higher pressure after reasonable design and manufacturing process. At the same time, the sealing structure of the reactor is also crucial to ensure that no leakage occurs under high pressure.
3. Material corrosivity: This is a key factor in selecting materials. If the material is highly corrosive, such as concentrated acid, concentrated alkali, etc., enameled reactors, glass-lined reactors or reactors made of special alloys (such as Hastelloy) are better choices. For materials with weaker corrosiveness, stainless steel reactors can meet the needs; while carbon steel reactors are suitable for reactions of basically non-corrosive materials.
Q3:What types of stirring devices are there for reactors and how to choose them?
1. Paddle agitator: It has a simple structure and consists of a paddle and a stirring shaft. It is suitable for the mixing and heat transfer process of low-viscosity liquids, such as in some simple solution preparation reactions, it can quickly mix the materials evenly. Its paddles are of various shapes and sizes, such as flat paddles, inclined paddles, etc., according to specific reaction requirements.
2. Anchor agitator: The shape is similar to an anchor, and the paddles are close to the wall of the kettle. It is mainly used for stirring high-viscosity materials, which can effectively prevent the accumulation of materials near the wall of the kettle and promote the overall mixing of materials. In some high-viscosity polymer synthesis reactions, anchor agitators can play a good stirring effect and ensure uniform reaction.
3. Turbine agitator: The stirring intensity is high and can produce radial and axial liquid flow. It is suitable for reactions that require rapid mixing, dispersion and suspension of solid particles. For example, in suspension polymerization reactions, solid particles can be evenly suspended in the reaction liquid to ensure the consistency of the reaction. The number and angle of the turbine agitator blades can be adjusted according to the characteristics of the reaction.
4. Propeller agitator: It produces strong axial liquid flow and is often used in systems that require large flow circulation stirring. In large reactors, propeller agitators can circulate materials quickly and improve reaction efficiency. For example, in some continuous production reactions, the reaction conditions of materials at all locations can be ensured to be consistent.
5. Selection method: According to the viscosity of the material, paddle and propeller agitators can be selected for low-viscosity materials; anchor agitators are selected for high-viscosity materials. If complex reactions such as suspension and dispersion of solid particles are involved, turbine agitators are more suitable. At the same time, factors such as the volume of the reactor and the requirements of the reaction process should also be considered to comprehensively determine the type of stirring device.
Q4: What are the reasons for the temperature out of control during the operation of the reactor, and how to solve it?
1. Reason: First, it may be a fault in the temperature control system, such as a damaged temperature sensor, which makes it impossible to accurately measure the reaction temperature, and then the control system cannot correctly adjust the heating or cooling device. Secondly, there is a problem with the heating or cooling device itself, such as a short circuit in the heating rod and a blockage in the cooling water pipe, which cannot work normally and affect the temperature regulation. In addition, the reaction heat of the material changes suddenly during the reaction, such as an abnormally accelerated reaction rate, which generates a large amount of heat, and the cooling system cannot take it away in time, which will also cause the temperature to be out of control.
2. Solution: For temperature control system failures, replace the damaged temperature sensor in time, and calibrate and debug the control system to ensure that it can accurately measure and control the temperature. If there is a problem with the heating or cooling device, repair the specific fault, such as replacing the heating rod and unblocking the cooling water pipe. During the reaction process, pay close attention to the reaction of the materials. If the reaction heat is abnormal, the reaction rate can be controlled by adjusting the addition speed and concentration of the reaction materials, and cooling measures can be strengthened, such as increasing the cooling water volume or reducing the cooling water temperature, so that the temperature of the reactor returns to normal.
Q5:What does the daily maintenance of the reactor include?
1. Appearance inspection: Check the reactor shell regularly for deformation, cracks, corrosion, etc. If there are any problems, deal with them in time. Check whether the bolts at each connection are loose to ensure the overall structure of the equipment is stable.
2. Maintenance of the stirring device: Check whether the blades of the stirrer are worn, deformed or loose, and repair or replace them in time if necessary. Check and maintain the sealing device of the stirring shaft to ensure good sealing and prevent material leakage. At the same time, regularly add lubricating oil to the bearings, gears and other transmission parts of the stirring device to ensure their normal operation.
3. Maintenance of the temperature control system: Check the accuracy of the temperature sensor and calibrate it regularly. Maintain the heating and cooling devices, such as cleaning the dirt on the surface of the heating rod to prevent it from affecting the heating efficiency; clean the scale and impurities in the cooling water pipeline to ensure the cooling effect.
4. Pressure system maintenance: If the reactor has a pressure system, check whether the pressure gauge is working properly and calibrate it regularly. Check whether the safety valve is sensitive and reliable to ensure that the pressure can be released in time when the pressure is too high to ensure the safe operation of the equipment.
5. Cleaning work: After each reaction, clean the inside of the reactor in time to remove residual materials to prevent materials from accumulating in the reactor and corroding the reactor body, and also facilitate the next reaction.
Q6: What are the safety devices of the reactor and how to ensure their effective operation?
1. Safety devices: Common safety devices include safety valves, bursting discs, pressure gauges, thermometers, emergency shut-off valves, etc. The safety valve automatically opens to release pressure when the pressure in the reactor exceeds the set value to prevent explosion caused by excessive pressure; when the pressure rises abnormally and the safety valve fails, the bursting disc can quickly break and release pressure, playing a double protection role; the pressure gauge is used to monitor the pressure in the reactor in real time; the thermometer monitors the reaction temperature; the emergency shut-off valve can quickly cut off the material in and out of the pipeline in case of an emergency to prevent the accident from expanding.
2. Ensure effective operation: Regularly calibrate the safety valve to check whether its sealing performance and opening pressure are normal, which can be done through online calibration or offline calibration. The bursting disc should be replaced regularly according to the prescribed service life to avoid performance degradation due to long-term use. The pressure gauge and thermometer need to be calibrated regularly to ensure that the measurement data is accurate and reliable. The emergency shut-off valve should be tested manually and automatically regularly to ensure that it can act quickly and accurately in an emergency. At the same time, a complete equipment safety management system should be established to keep detailed records of the maintenance, inspection, and calibration of safety devices to ensure that all safety devices are always in good operating condition.
Q7:What are the precautions for the installation of the reactor?
1. Foundation construction: Before installing the reactor, ensure that the foundation is firm and flat. According to the weight, size, and vibration of the reactor during operation, design a suitable foundation structure and use reinforced concrete and other materials for foundation construction. The flatness error of the foundation surface should be controlled within the specified range to ensure the stability of the reactor installation.
2. Equipment lifting: Use appropriate lifting equipment, such as cranes, to ensure the safety of the reactor lifting process. During lifting, pay attention to protecting the shell, nozzle and other parts of the reactor to prevent collision damage. At the same time, strictly follow the requirements of the equipment installation manual and select the correct lifting point to avoid deformation of the reactor due to improper lifting.
3. Installation location selection: The reactor should be installed in a well-ventilated, dry place away from fire sources and flammable materials. At the same time, the convenience of equipment operation, maintenance and overhaul should be considered, and sufficient space should be reserved. For reactors with corrosive materials, the installation location should be well treated with anti-corrosion to avoid corrosion in the surrounding environment.
4. Connection and sealing: During the installation process, ensure that the connection between each pipeline, valve and reactor is accurate. For the sealing parts, appropriate sealing materials should be selected and sealed according to the prescribed installation process to ensure good sealing performance and prevent material leakage. After the connection is completed, pressure testing and leakage inspection should be carried out to ensure the quality of equipment installation.
