Mist eliminator inlet nozzle

The equipment used to remove the anolyte mist referred to in Section 9.1.1 is quite similar. Mist concentrations and design levels are higher than in the dry mist eliminator, by a factor of about four. A spray nozzle connected to a water supply is a useful addition at the gas inlet. This allows occasional washing of the elements. 

The process is carried out in a simple, vertical bubble contactor as shown in Figure 16-7. The contactor is equipped with inlet and outlet gas nozzles,. slurry feed and overflow nozzles, a drain, a manway, a mist eliminator, and a gas distributor. Gas bubbles rise from the distributor and provide the agitation to keep the zinc oxide particles in suspension. 

The space between the inlet nozzle and the mist eliminator is provided for the droplets to fall back to tire bottom of the separator. Too small a distance may cause the droplets to be carried away with the gas stream. The following criteria is often used for estimating the distance h3 ...
