Abstract

The invention provides a constant-pressure additive hopper for a reaction kettle and an application method of the constant-pressure additive hopper. An air inlet, an air outlet and an air vent are formed in the upper end of a hopper body, a discharging hole is formed in the lower end of the hopper body, and the air vent and the discharging hole are respectively connected with the reaction kettle through a pipeline. The air inlet and air outlet of each pipeline are controlled through a valve, and an effect for replacing inert gases in the hopper can be achieved, so that the experimental stability can be improved. Meanwhile, a positive pressure effect and a negative pressure effect are respectively achieved by virtue of different control methods of each valve, the feeding problem is solved, and the process control is also reduced.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and in particular relates to a constant-pressure additive hopper for a reaction kettle and a use method thereof. Background technique [0002] The polyester synthesis reaction is divided into two stages of esterification and polycondensation. The current experimental reactors are almost all one reactor for esterification and polycondensation. Since the reaction is carried out under airtight conditions, all raw material additives must be put in together before the esterification. During the reaction process, the esterification reaction is under positive pressure, and the polycondensation reaction is under negative pressure. For scientific research, it is necessary to add many auxiliary agents or additives with different functions in the reaction. Some of these functional auxiliary agents need to be added in the esterification section, and some need to be added in the polycondensation section. H...
