Abstract

The invention relates to a devolatilization device, which comprises a devolatilization device body, a gas phase outlet is formed in the top of the devolatilization device body, material inlets are formed in the upper portion of the devolatilization device body, a material outlet is formed in the bottom of the devolatilization device body, a material distributor is installed in the devolatilization device body, the material distributor is located on the upper portion of the devolatilization device body, and the number of the material inlets is two; the material distributor is formed by splicing a plurality of distribution pipes and is shaped like a Chinese character mu, the material distributor is transversely arranged, two feeding ports are formed in the upper side face of the material distributor and are symmetrical about the central axis of the material distributor, and a plurality of discharging ports are formed in the lower side face of the material distributor; and the material inlets are connected with the feeding ports in a one-to-one correspondence mode. The distribution pipes are relatively uniformly distributed in the cross section of the barrel body, so that the sprayed liquid drops uniformly fill the space in the barrel body, local crowding and mutual collision of the liquid drops are not excessively formed, the liquid drops are not increased, the area of a volatilization interface is not excessively reduced, and a good volatilization effect is kept; and an ascending channel is reserved for gas.

Description

technical field [0001] The invention relates to chemical equipment, in particular to a devolatilizer. Background technique [0002] Polymerization is one of the most commonly used processes in chemical engineering. Usually, after the polymerization reaction reaches a certain conversion rate, it is very difficult to continue the conversion. Unconverted monomers need to be removed from the polymer to obtain pure polymer. It is generally required that the monomer residue in the final product is not more than 800ppm. This process of removing unconverted monomers is called devolatilization. A small amount of polymer solvent is also removed during devolatilization. There are many traditional devolatilization methods, such as heating flash method, heating stirring method, screw extrusion method and so on. Contents of the invention [0003] The invention provides a devolatilizer. [0004] Technical scheme of the present invention: [0005] A devolatilizer, the devolatilizer...
