An S-shaped multi-strip guide hole tray is formed by parallel arrangement of long-strip-shaped plates with transverse-S-shaped sections. The adjacent plates are arranged in a stagger mode at intervals, and the intervals form airflow passageways. Each plate is composed of a first vertical unit, a second horizontal unit, a third vertical unit, a fourth horizontal unit and a fifth vertical unit, wherein the fourth horizontal unit is perpendicular to the liquid flow direction, air outlets are formed in the first vertical unit, and strip-shaped guide holes are formed in the fourth horizontal unit and are distributed into a triangle. By the adoption of the tray, gas-liquid mass transfer is improved, sufficient mixing of gas phase and liquid phase in a flue gas desulfurizer is effectively achieved, and then desulphurization efficiency reaching 95% or above is realized, airflow on the cross section in the tray can be distributed uniformly, and the problem that airflow in the tray is distributed unevenly is solved rem
