Abstract

As an important steam-water separation device in nuclear power steam generators, the corrugated plate separator can separate water from steam, improve the dryness of the steam delivered, and ensure the safe operation of steam turbines and other equipment. This paper designs a corrugated plate structure with variable plate-hook spacing, and based on this structure, designs single-hook and double-hook corrugated plates with variable plate-hook spacing. At the same time, using numerical calculation methods, the performance of the corrugated plates with variable plate-hook spacing is compared with that of single-hook and double-hook corrugated plates with fixed plate-hook spacing. The separation efficiency and pressure drop are evaluated from two aspects, and the flow characteristics of internal airflow and the separation characteristics of droplets are discussed. Compared with traditional single-hook and double-hook corrugated plates, the gradual increase in plate-hook spacing promotes continuous acceleration of airflow, enhances inertial collisions between droplets and between droplets and solid walls, and achieves higher separation efficiency at lower inlet airflow speeds.
