Description
Technical Parameters
High pressure stirred reactor, also known as high-pressure reactor, is a device that mixes and reacts reactants under high pressure conditions through a stirring device. It is suitable for various chemical reactions that require high-pressure environments, such as catalyst preparation, synthesis of polymer materials, drug synthesis, and biomass conversion. The working principle is to use a stirring device to mix and stir the reactants, while controlling the reaction temperature through a heating or cooling system, and controlling the reaction pressure through a pressure control system. During the stirring process, the reactants are thoroughly mixed and uniformly heated, thereby accelerating the progress of the chemical reaction. It has a wide range of applications in fields such as chemistry, medicine, and materials. For example, in the petroleum and chemical industries, it can be used for the preparation of catalysts and the synthesis of polymer materials; In the field of medicine, it can be used for processes such as drug synthesis and biomass conversion; In the field of materials science, it can also be used for the preparation of nanomaterials and superhard materials.

Products Parameter
Products Features
TGFY-C high pressure stirred reactor is a kind of laboratory bench-top high-pressure reactor, with various design capacities, including 50ml, 100ml, 250ml, 500ml and 1000ml, which can meet different experimental and production requirements.
High pressure stired reactors are usually presented as cylindrical or spherical hermetic vessels made of stainless steel (e.g. 304/316) to ensure their stability and corrosion resistance in high temperature and high pressure environments. The surface of the kettle body may be polished to maintain cleanliness and to facilitate observation of the internal reaction. The top of the kettle body is usually equipped with connections such as inlet and exhaust ports, pressure gauges, thermometers, etc. to facilitate experimental operation and data monitoring.
The stirring system is an important part of the equipment and is usually located in the center of the kettle. The stirrer is connected to the motor drive via a magnetic coupling to ensure that the stirring operation is carried out in a sealed environment. The shape and size of the stirrer is designed according to the specific reaction requirements to ensure that the material is adequately mixed and stired in the kettle.
Maintenance
The steps of cleaning the kettle are as follows:
1.
Fill the reaction solvent into the high-pressure reaction kettle from the exhaust valve, wash off most of the residues, and then inject water into the half kettle to stir for 10 minutes. At this time, the kettle cover can be opened.
2.
When cleaning the High pressure stired reactors kettle, the kettle cover and sampling valve must be cleaned, and at the same time, nitrogen gas should be filled when there is water in the kettle.
3.
For the reaction kettle that is not used for the time being, add 70% clean anhydrous ethanol into the reaction kettle for soaking, and do not tighten the screws. After the autoclave is cleaned, it can be used next time.
Cleaning method
Ensure that the reactor has cooled to a safe temperature and that the internal pressure has been relieved.
Prepare the necessary cleaning tools, chemical cleaning agents (if required) and safety equipment.
Hydraulic rinsing:
Reverse Rinse: Flush impurities from inside the membrane and the inlet end face with raw water.
Forward rinsing rinse: Flush the impurities inside the membrane and the end face with raw water, and clean the tubular ultrafiltration membrane according to the operation status.
According to the nature of the residue in the reactor, select the appropriate chemical cleaning agent.
Prepare the cleaning solution and make sure that the cleaning agent is compatible with the material of the reactor.
Preparation of cleaning solution: Prepare a cleaning solution of appropriate concentration according to the instructions for use of the cleaning agent.
Input cleaning solution at low flow rate: Mix the cleaning solution with a cleaning pump and preheat the cleaning solution at a low flow rate. Then replace the raw water in the element at the lowest possible pressure.
Circulation: Allow the cleaning solution to circulate through the kettle, ensuring that the cleaning solution is in full contact with the inner walls and agitator.
Immersion: Stop the cleaning pump and allow the kettle to be completely immersed in the cleaning solution. For stubborn pollutants, it is necessary to extend the soaking time.
High-flow pump circulation: use a high-flow pump to circulate the cleaning solution to rinse off the contaminants washed down by the cleaning solution.
After cleaning is complete, rinse the reactor with water to ensure that all cleaning agents have been rinsed off.
Inspect the inside of the kettle to make sure there are no residues or impurities.
Maintenance methods
Regular inspection:
Regularly check the sealing performance of the reactor to ensure no leakage.
Check the operation of the stirrer to ensure good stirring effect.
Check the heating and cooling system to ensure its normal operation.
Retail Big Data
Regularly lubricate and fasten the reactor to ensure its stable operation.
Replace the wearing parts, such as seals, stirrers, etc. regularly according to the usage.
Record management:
Establish the use and maintenance records of the reactor to record the date and content of cleaning, repairing and replacing parts.
Periodically analyze the records to assess the performance of the reactor and predict possible problems.
By following the above cleaning and maintenance practices, you can ensure the efficient operation and long-term stability of your machine.
