Our gas-liquid separator incorporates the following design features:
1. Compatibility Advantages of SUS304 Stainless Steel
SUS304 stainless steel effectively resists corrosion from weak acids and low-concentration sulfides (H₂S < 200mg/L) commonly found in pulp and paper wastewater. It ensures a service life of over 20 years.
2. Tangential Feed Design in the Secondary Reaction Chamber
The tangential angle and cylinder diameter ratio are precisely matched. The vortex generated by tangential inlet creates radial stratification of gas and liquid phases: biogas is discharged through the top gas collection pipe, while sludge-water mixture returns to the mixing zone via the reflux pipe. After the rotation kinetic energy dissipates, unseparated fine droplets sink along the cylinder wall under gravity, further reducing the liquid content carried by biogas.
3. Dedicated Biogas Inlet in Secondary Reaction Chamber
An independent biogas inlet pipeline, separated from the tangential water feed line, prevents clogging from high-concentration sludge backflow.
4. Visual Inspection Window Configuration
The viewport utilizes tempered glass or transparent polycarbonate, equipped with spray-cleaning functionality to maintain visibility by preventing scaling.
5. Conical Bottom for Liquid Recirculation
The conical base guides separated sludge-water mixture to uniformly recirculate along tangential paths, preventing localized turbulence-induced sludge accumulation.
6. Side Maintenance Access with Integrated Ladder
Service ladders enable routine inspection of biogas collection pipes, pressure sensors, and explosion-proof devices (e.g., flame arresters) at the separator top. It enables quick response to emergencies like biogas leakage or pipeline blockage.
