What is the specific function of the plug valve of the catalytic regenerator? How is it installed? How is the catalyst specifically upgraded?
The function of the plug valve is to adjust the circulation amount of the catalyst, but it depends on what kind of process you are using, whether it is a double regenerator, or a coaxial single settler, etc.! In the double regenerator, the plug valve mainly adjusts the amount of catalyst from one to two and then increases it, mainly relying on the main air to increase it! ! In the coaxial single settler, the plug valve mainly regulates the amount of burnt catalyst from the standpipe to be generated to the regenerator! In the riser, dry gas or steam is used as the lifting medium for the catalyst.
