　　Attention to the use of reaction kettle

　　A reactor is a type of reaction equipment that must be operated carefully, otherwise it may be damaged due to various reasons, leading to production stoppage. There are many aspects to pay attention to when operating a reactor.

　　Firstly, it is necessary to strictly operate the reactor according to the rules and regulations.

　　Secondly, before operation, carefully check for any abnormalities. During normal operation, do not open the upper cover or touch the wiring terminals on the board to avoid electric shock; It is strictly prohibited to operate under pressure; During the nitrogen pressure test, carefully observe the changes in the pressure gauge. Once the test pressure is reached, immediately close the nitrogen valve switch; The heating rate should not be too fast, and the pressurization should also be carried out slowly, especially the stirring speed, which is only allowed to increase slowly.

　　Afterwards, when the kettle body is heated to a higher temperature, do not come into contact with the kettle body to avoid; After the experiment, the temperature should be lowered first. Do not cool quickly to prevent damage caused by excessive temperature and pressure differences. At the same time, it is necessary to unplug the power supply in a timely manner.

　　At the same time, attention should be paid to maintenance of the reaction kettle after use, so that the high-pressure kettle can have a better service life.

　　Maintenance of reaction kettle

　　(1) Installation location: The reaction vessel should be installed in a high-pressure operating room that meets explosion-proof requirements. When multiple reaction vessels are equipped, they should be placed separately, and a safe explosion-proof wall should be used to separate each two vessels. Each operating room should have a passage and outlet to the outside, and good ventilation should be ensured when explosive media is present.

　　(2) After opening the packaging, check for any damage to the equipment. Install the equipment according to the structural diagram based on the equipment model, and verify the components provided according to the packing list. If the heating method is thermal oil electric heating, please purchase the corresponding model of thermal oil according to the operating temperature (note: thermal oil does not allow moisture) and add it. When adding, open the oil filling port on the upper part of the jacket and the oil level port on the upper part of the jacket. Add oil through the filling port until the oil level flows out; Twist the oil level port tightly afterwards, do not twist the oil filling port tightly to avoid pressure.

　　(3) Installation and sealing of kettle body and kettle cover: The kettle body and kettle cover are in line contact with the circular arc surface using gaskets or conical surfaces, and are tightly pressed against each other by tightening the main nut to achieve a good sealing effect. When tightening the nut, it must be diagonally symmetrical and gradually tightened multiple times with even force. It is not allowed for the kettle cover to tilt to one side to achieve a good sealing effect. When tightening the main nut, do not exceed the specified tightening torque range of 40-120N. M to prevent the sealing surface from being crushed or overloaded for wear. Special care should be taken for the sealing surface. Before each installation, use a soft paper or cloth to wipe the upper and lower sealing surfaces clean, and be careful not to touch the sealing surfaces of the kettle body and lid. If operated reasonably, it can be used more than tens of thousands of times. After the sealing surface is damaged, it needs to be reprocessed and repaired to achieve good sealing performance. When disassembling the kettle cover, it should be slowly lifted up and down to prevent the sealing surfaces between the kettle body and the kettle cover from colliding with each other. If gaskets (PTFE, aluminum, copper, asbestos, etc.) are used for sealing, a good sealing effect can be achieved by tightening the main nut.

　　(4) The installation of valves, pressure gauges, and safety valves achieves a sealing effect by tightening the positive and negative nuts. The circular sealing surfaces at both ends of the connection must not rotate relative to each other. When assembling all screw connections, lubricant or graphite mixed with oil must be applied to prevent them from biting. The use of valves: Needle valves are line sealed, and good sealing performance can be achieved by gently rotating the valve needle and compressing the sealing surface. Excessive force is prohibited to avoid damaging the sealing surface.

　　(5) After the equipment is installed, introduce a certain amount of nitrogen and maintain pressure for 30 minutes to check for any leaks. If any leaks are found, use soap foam to locate the leakage points in the pipelines and pipe openings. After finding them, release the gas and tighten them. Then, conduct a nitrogen pressure test again to ensure that there are no leaks before starting normal operation.

　　The reaction kettle consists of a kettle body, kettle cover, jacket, stirrer, transmission device, shaft seal device, support, etc. When the aspect ratio of the mixing device is large, multiple layers of mixing blades can be used, and it can also be selected according to the user's requirements. A jacket is installed outside the kettle wall, or a heat exchange surface is installed inside the reactor, or heat exchange can be achieved through external circulation. The support seat can be of the support type or ear type. Gear reducers should be used when the speed exceeds 160 revolutions per minute The number of openings, specifications, or other requirements can be designed and manufactured according to user requirements.

　　1. Packing sealing is usually used under normal or low pressure conditions, with a pressure of less than 2 kilograms.

　　2. In general, mechanical seals are used for medium pressure or vacuum situations, with a pressure of negative pressure or 4 kilograms.

　　3. Magnetic sealing will be used under high pressure or high volatility of the medium, usually when the pressure exceeds 14 kilograms. Except for magnetic seals that use water cooling, other sealing forms will increase the cooling water jacket when the temperature exceeds 120 degrees.
