Conclusions
In this paper, a lab-scale reverse spray washing hydrodynamic system was established, and the effects of liquid inlet mode, liquid flow rate and gas flow rate on
gas–liquid two-phase flow pattern, fluid structure and gas phase pressure characteristics were investigated, and load performance was drawn under different conditions.
The experimental results show that:
(1) By changing the axial and tangential liquid flow ratio of the nozzle and the
liquid/gas ratio of the scrubber, the gas–liquid two-phase flow in the washing
tube can be divided into four flow types: hollow tapered, foaming, annular and
column types. Foaming flow is more suitable for separating the fine particles in
flues gas.
