An experiment investigation of particle collection efficiency in a fixed valve tray washing column

A novel application of the fixed valve tray column has been conceived. Fig. 1 is the schematic of a fixed valve tray column scrubber system. The structure of the fixed valve tray is shown in Fig. 2. Particle collection efficiency on each plate was investigated. It can be seen from Fig. 3 that the collection efficiency of particles larger than 5 μm can achieve above 90%, and the collection efficiency of particles finer than 1 μm drop to around 60% rapidly on the first plate. On the second plate the efficiencies of particles larger than 1 μm are in the range of 40%-60%, while for particles finer than 1 μm the collection efficiency is 30% due to purification effect of the first plate.
