At the same time, the stirrer can accelerate the heat and mass transfer process. The speed reducer is used for controlling the stirrer to obtain different rotating speeds so as to adapt to different material reactions.
When the glass lining reaction kettle TJR-K5000 is used for lactone synthesis reaction, the reaction degree is judged by measuring the temperature of materials in the glass lining reaction kettle, the lactone synthesis reaction temperature rises quickly, a flange type thermometer sleeve of the traditional glass lining reaction kettle is generally inserted into a position of 1/3 of the reaction kettle in order not to influence stirring, but is still a certain distance from the kettle bottom, generally about 70cm, when initial feeding is carried out, the fed-batch materials are less, the temperature of the materials in the reaction kettle cannot be contacted by a thermometer, the temperature measurement distortion of the materials in the reaction kettle is easily caused, and the judgment of the reaction degree is influenced, so that the feeding speed of the materials in the reaction is influenced, and the lactone synthesis reaction yield is low.
The glass lining reaction kettle TJR-K5000 is provided with a large sealing head, and the structure of the reaction kettle has the risk of leakage of raw material hydrocyanic acid for lactone synthesis reaction, and the airtight structure is unreasonable.
No solution to the above problems has been found yet.
