A horizontal shaftless agitated reactor designed for emulsion polymerization is a specialized type of reactor used in the chemical industry, particularly for the production of polymers through emulsion polymerization. Emulsion polymerization is a process where monomers are polymerized in an aqueous medium using a surfactant to stabilize the growing polymer chains as they form. This method is widely used to produce various types of polymers and copolymers, including those used in adhesives, coatings, and latexes.

A shaftless agitator impeller is designed to improve mixing efficiency and uniformity in reactors, especially in applications like emulsion polymerization where even mixing is critical. Traditional shafted mixers can sometimes lead to uneven mixing due to issues like dead zones or turbulence that can affect the homogeneity of the mixture. A shaftless agitator aims to address these problems by providing a more efficient and uniform mixing action.

A double helix ribbon impeller is a type of mixer designed to optimize circulation and mixing in a reactor. This design is particularly useful in applications where thorough mixing is critical, such as in emulsion polymerization, where uniform dispersion of monomers and the control of particle size distribution are important factors for the quality of the final product.

Ø  A novel double-helical ribbon biomass catalytic pyrolysis reactor was designed.

Ø  The experimental results supported the validity of the DEM simulation.

Ø  Mixing RSD was closely related to the impeller outer diameter and rotation speed.

Ø  Mixing rate could be optimized by adjusting the inner diameter and pitch.

Ø  The characteristic size of particles was firstly proposed in scale up analysis.
