Technical Field

The utility model relates to a polypropylene production facility technical field specifically is a gas, liquid, solid three-phase splitter is used in polypropylene production.

Background

A water washing tower exists in the polypropylene production process of Spheripol and ST of a medium petrochemical industry of Basell which adopt a loop reaction kettle, and the water washing tower mainly removes polypropylene dust in process gas. The bottom discharge of the water washing tower (T501) and the water washing tower (T-502) contains water, PP powder and part of gas, and the three-phase mixture is discharged into a water tank beside the T-502 through a pipeline. The same problem also exists in the granulating water system of the PP and PE granulating device, and most manufacturers adopting the two PP production processes at present manually salvage floating PP powder after discharging water into a pool and settling for a period of time. This approach has the following disadvantages:

(1) The working environment of the site is easy to be dirty, and the pp powder is easy to leak to other places in the operation process.

(2) The filtering precision can not be ensured, and no filtering element participates in the whole process; the PP powder easily flows downstream through the overflow hole. The downstream purge pressure is increased.

(3) The smell on site is too big, the leakproofness of whole pond is relatively poor, and the peculiar smell diffusion is very fast in the manual work is dragged for the powder in-process, and is the most serious.

(4) The cleaning is carried out regularly by personnel, and the labor is occupied. And the working environment is poor.
