The Numerical Simulation Research of Spiral Solid-Liquid Separators
In water production-reinjection system, a spiral solid-liquid separator is installed at the inlet of the electric submersible pump (ESP) to prevent solid materials in the re-injected water from plugging formation pore and keep the efficiency of water injection. In order to determine optimum structural parameters and operating parameters of the separator, numerical simulation was conducted to analysis the effect of spiral laps, spiral pitch, inlet velocity, etc. on separation properties. By analysis and comparison, spiral laps of 5, pitch of 18 mm are the most suitable structure parameters. In operating parameters, the pressure drop and separation efficiency increase with the inlet velocity increasing. The results provide reference for further research of the spiral solid-liquid separators.
