The inclined plate type liquid collector has the functions of collecting liquid, uniformly distributing air flow, promoting mixing, reducing mutual entrainment of gas and liquid, and the like, but has the defects that large liquid amount is difficult to collect, liquid leakage is difficult to avoid, the liquid has insufficient residence time to completely separate bubbles entrained in the liquid, the disassembly and assembly are inconvenient, and the like. The above-mentioned liquid collectors have respective drawbacks which reduce the performance of the devices and also limit their applicability.
For this purpose, a multi-layer liquid collecting liquid collector is designed to overcome the above problems.
