Cylindrical single-layer reactorIt can use a circulating water vacuum pump to generate negative pressure and suck in various liquids or gases, and can also be refluxed or distilled under different temperature conditions. If a low-temperature test is to be conducted, a cooling coil can be added to the inner wall of the water bath and a low-temperature coolant circulation pump can be configured for low-temperature operation. Internally, stirring reactions can be carried out using hot water or hot oil for heating reactions. Cooling coils can be added to the oil bath pot for cooling reactions. Under constant temperature conditions, stirring reactions can be carried out in a closed glass reactor under normal or negative pressure conditions according to usage requirements, and reflux and distillation of reaction solutions can be carried out. It is an ideal pilot and production equipment for modern fine chemical plants, biopharmaceuticals, and new material synthesis. Various solvent synthesis reactions can be carried out under constant temperature conditions. The reaction part of the instrument is a controllable fully sealed structure, which can continuously inhale various liquids and gases using negative pressure, and can also perform reflux or distillation at different temperatures.
The bypass valve should be opened first, and then the steam valve should be slowly opened to drain the accumulated water. After that, the pipe bypass valve and the steam trap should be used for drainage to preheat the jacket.
The heating and warming operation should be carried out under stirring conditions as much as possible. First, slowly open the steam shut-off valve and introduce steam through the steam shut-off valve to reach 0.1Mpa. After holding for 15 minutes, slowly increase the pressure and temperature. The pressure rise rate should be controlled within 0.1Mpa in less than 10 minutes. The pressure inside the jacket must not exceed the specified value, and the temperature rise must also meet the process requirements.
During the process of dropwise addition and insulation, it is necessary to regularly check the temperature and pressure of the reaction vessel, comprehensively observe the condition of the dropwise added materials and the materials inside the reaction vessel, and make corresponding records. When the temperature, pressure, and material interface of the reaction vessel are abnormal, corresponding measures should be taken in a timely manner to maintain a normal reaction state and prevent equipment and personal accidents.
After feeding the materials, adjust the relevant valves to the appropriate opening and closing positions to start the mixing process. In the initial stage, it is necessary to strengthen the detection of the mixing operation status. If there are obvious abnormalities such as noise and vibration, emergency shutdown should be carried out. If solid powder or other substances are added to the reaction vessel, stirring can only be started after sufficient dissolution.
When taking materials from the reaction vessel, stirring must be stopped for at least 2 minutes to ensure that there are no other safety hazards before proceeding. Not easy to use, hard metal containers that are prone to detachment should be inserted into the reaction vessel for sampling to avoid damaging the enamel glass surface.
Cylindrical single-layer reactorStrictly follow the process operation procedures during the operation of traditional Chinese medicine, and strictly prohibit overheating, overpressure, and overload operation; Once abnormal situations such as overheating, overpressure, and overload occur, corresponding measures should be taken immediately according to the process regulations. It is strictly prohibited to react beyond the specified liquid level in the reactor.
Check the operation of the equipment at any time, and if any abnormal situations are found, stop immediately for inspection.
