The reaction kettle is usually used for material reaction, stirring, rectification, cooling, mixing, alkylation, sulfurization, nitration, polymerization, condensation and other functions. The reaction kettle is divided into normal pressure and pressure during use, so it is necessary to understand its performance when using it, and operate it according to the regulations:
1. Before the
Reactor works, the pipelines and valves related to the reaction should be checked first, and the materials can be fed only when the conditions for receiving materials are ensured.
2. Before starting the stirring part of the reactor, check whether the stirring motor, reducer, mechanical seal, etc. are normal, whether the oil level of the reducer is appropriate, and whether the cooling water supply of the mechanical seal is normal. In the case of ensuring no doubt, start the stirring and put in the material according to the specified amount. The reaction kettle or the reaction kettle stirring the bottom bearing is strictly prohibited from idling, and the stirring can be started only when the bottom bearing is immersed under the leaf surface. Strictly implement the process operation rules, pay close attention to the temperature and pressure in the reactor and the pressure of the jacket of the reactor, and strictly prohibit over-temperature and over-pressure.
3. During the reaction process, the reaction kettle should be inspected, and problems should be dealt with in time.
4. If the over temperature phenomenon occurs in the reaction kettle, immediately cool down with water, and the temperature after cooling should meet the technological requirements.
5. If overpressure occurs in the reactor, immediately open the emptying valve and release the pressure urgently.
6. If the reactor is stopped due to power failure, the feeding should be stopped. If the power is cut off during feeding, feeding should be prohibited and the water should be cooled. After long-term parking, the residual liquid in the kettle should be cleaned, and the bottom valve, feed valve, intake valve, discharge valve and other reaction kettles should be closed. Precautions for use of the reactor: temperature setting of the text displayer and recorder on the instrument box in the complete set of equipment, For the usage of the instrument, please refer to the instrument manual or according to the manufacturer's instructions. The text display instrument controls the temperature setting, which generally fluctuates up and down by 1-3 °C. The user should adjust it to the appropriate position according to the actual situation.
7. The reaction kettle adopts an integrated temperature transmitter with an external wire, which has been calibrated before leaving the factory. If the user needs to adjust, it must be calibrated according to the requirements of the instrument. The heating layer of the reactor contains heating medium. When heating, it should be noted that the emptying port or the emptying valve must be kept open, and attention should be paid to heating in a closed state to avoid danger. Regularly check the display and working conditions of pressure gauges and safety valves to avoid the quality of products or danger due to display errors or damage to accessories. Regularly observe the liquid level of the heating medium such as water or oil, and add more when it is insufficient to avoid dry burning of the electric heating system.
8. Pay attention to observe when the reactor is heated, such as the overflow of the expansion port medium, whether the stirring system lacks lubricating medium, etc., to prevent personnel from being splashed by the overflow and the motor running in a non-lubricated state.
