METHOD FOR REDUCING OR AVOIDING FORMATION OF BUBBLE IN CHEMICAL AND PHYSICAL SUBSTANCE CONVERSION PROCESS AND DEVICE FOR EXECUTING SAID METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for avoiding or reducing formation of bubbles generated by a chemical and physical conversion precess in a liquid medium. SOLUTION: The substance conversion process is performed in a blowing-up reactor 1 which has not a built-in body and is provided with a tapered lower part and favorably provided with a conical lower part 3 and a gas injection device 6. The contents in the reactor 1 are sufficiently mixed by using jet circulation for blowing up the contents through gas injection. The device is equipped with a port 5 for discharging suspension containing plenty of solid matter in the tapered part. The blowing-up jet reactor 1 is provided with a pipe 8 which is terminated in the range of a formed bubble flow and used to introduce a liquid medium. Therefore, this method is specially suitable to execute a crystallization method.
