AI Technical Summary
Existing technologies suffer from low separation efficiency, high energy consumption, and complex maintenance in the treatment of spray liquid from the tail gas of distillers' grains drying. Traditional sedimentation tanks have low colloid removal rates, electric centrifuges have high power consumption and maintenance costs, pressure membrane filtration technology suffers from severe membrane fouling, and existing gravity filtration technology has limited filter bed capacity, which cannot meet the high-efficiency treatment requirements of spray liquid with high suspended solids concentration.
A spray liquid separation device based on gravity flow and valveless filter is adopted. Through the combination of mixing tank, overflow tank and valveless filter, gravity drives the liquid flow. Combined with the three-stage synergistic process of coagulation-sedimentation-adsorption, PAC/PAM agent is used to reduce the colloidal zeta potential. 60° corrugated filter plate is used to improve sedimentation efficiency. Fine quartz sand layer and activated carbon layer are built into the valveless filter for further filtration.
It achieves zero-power conveying, reduces energy consumption by 100%, increases colloid removal rate to 75%, and suspended solids removal rate to 92%, while reducing the footprint by 40%, making it suitable for small and medium-sized enterprises.
