AI Technical Summary
Existing petrochemical feedstock filtration and separation equipment is prone to clogging of the filtration module when processing high-impurity and multiphase feedstocks, which affects production continuity and increases operation and maintenance costs.
Employing a multi-stage filtration structure and synergistic separation design, it utilizes a combination of wedge mesh, adsorption layer, and filter mesh, along with a spiral guide plate inside the separation tank, to achieve multi-stage filtration and centrifugal separation, reducing the risk of media blockage.
It significantly improves filtration and separation efficiency, extends filtration cycle, reduces operation and maintenance costs, and enhances the thoroughness of separation and product purity.
