The Paddle blade high-pressure reactor is a type of high-pressure reactor. It is suitable for chemical reactions of high temperature and high pressure, high vacuum, flammable, explosive, and highly toxic media. It can be designed and matched according to the different process requirements of users. Various materials can be designed with functions such as feeding under pressure, discharging under pressure, and remote pressure transmission. High-pressure reactors are mainly distributed in petrochemical, chemical, pharmaceutical, polymer synthesis, metallurgy, and other fields.
The Paddle blade high pressure reactor has the characteristics of static sealing, no leakage, no noise, no pollution, stable operation, simple operation, sturdy and durable, and compact structure, so it can be used in high temperature, high pressure, high vacuum, high speed, suspension, and convection. The reaction medium is completely in the state of static sealing, which can safely carry out the efficient reaction of flammable, explosive, highly toxic, hydrogen, and other harsh media.
The main sealing port of the high-pressure reactor adopts the A-type double-line seal, and the other sealing points adopt the sealing form of the line contact between the arc surface and the plane, and the arc surface and the arc surface rely on the high precision and smoothness of the contact surface to achieve good sealing effect.
Instructions for the use of high pressure reactors:
1. First of all, check whether the autoclave is clean and ready for use and confirm it, and replace or fill in the equipment use sign.
2. Check whether the valves on the supporting pipeline and the valves on the distributor are closed.
3. Check the steam valve for internal leakage. If there is internal leakage, replace the valve in time.
4. Check the state of the jacket. If there is circulating water or salt water in the jacket, confirm it according to the standard procedures. The circulating water is directly discharged, and the salt water is notified to the ice machine to be pressed back to the saltwater tank.
5. Open the upper feed, the lower part of the kettle, the condenser circulating water, and the distillation and reflux valves of the high pressure reactor, close the emptying and distillation receiving valves, open the exhaust gas absorption valve or connect the effective vacuum. Open the steam return valve at the bottom of the kettle and then open the steam inlet valve to heat the reaction kettle.
6. Raise the temperature of the kettle to 100~120℃ and keep it for 2 hours until the kettle body and supporting pipelines are dry. If the reaction kettle has been refluxed with water, keep it for 4 to 5 hours to ensure that the kettle body and accessories are all dry before cooling down.
7. Close the inlet valve, the feed valve, and the lower valve of the kettle, and introduce nitrogen into the kettle through the pipeline for protection and cooling. The purpose is to prevent the entry of water vapor into the air.
8. When the temperature of the kettle drops to T≤100℃, close the steam return valve, slowly open the circulating water, and drop to normal temperature (after the temperature is lower than 40℃, it can be cooled with frozen brine to speed up the cooling rate). During the enrichment process, the production staff should make relevant records.
9. Close all valves on the high-pressure reactor, exhaust gas absorption valves, and nitrogen valves for use.
The working principle of the high pressure reactor is: to put the reaction solvent in the inner layer for stirring reaction, and the interlayer can pass through different cold and heat sources (refrigerant liquid, hot water, or hot oil) for cyclic heating or cooling reaction. Through the interlayer of the high pressure reactor, a constant temperature (high temperature or low temperature) hot melt medium or cooling medium is injected to heat or cool the materials in the high pressure reactor at a constant temperature.
The material is reacted in the high pressure reactor, and the evaporation and reflux of the reaction solution can be controlled. After the reaction is completed, the material can be discharged from the discharge port at the bottom of the kettle, and the operation is extremely convenient.
The reaction medium can be put into the inner layer for stirring reaction, and the interlayer can be connected with different cold and heat sources (refrigerated liquid, hot water, or hot oil) for cyclic heating or cooling reaction. Through the interlayer of the high pressure re1actor, a constant temperature (high temperature or low temperature) hot melt medium or cooling medium is injected to heat or cool the materials in the high pressure reactor at a constant temperature. At the same time, the stirring reaction can be carried out under normal pressure or negative pressure according to the requirements of use.
