[0002] A polymerization kettle is a method or device for combining multiple raw materials, compounds or products. In chemical and biological processes, polymerization kettles are usually used to combine two or more substances through chemical reactions to form new compounds. This method can be applied in fields such as drug manufacturing, spice production, and plastic preparation.

[0003] When producing vinyl chloride polymerization, a polymerization kettle is required. The size of the suspension polymerization particles mainly depends on the shape, size and stirring intensity of the stirring paddle. During suspension polymerization, since the energy distribution in the current stirring kettle is very uneven, 70% of the stirring energy is dissipated in the area of the stirring paddle and its vicinity, which accounts for about 10% of the total volume. Therefore, in the area near the stirring paddle, due to the strong shearing action, the liquid droplets are easily dispersed. While in the area far from the paddle blade, the liquid droplets are prone to coalescence due to the long residence time. Content of the Utility Model
