Drift Eliminator is the key equipment in the FGD process, it must meet different requirements of operating conditions parameters of the flue gas desulfurization system from design to manufacturing. The best way is to design highest value of parameters into the worst operating conditions.
The area of the defogger is calculated to be 1.4 times than theoretical optimum value, since it is the basis of defogging efficiency. Generally, it is showed in the form of type of blades (two or three channels), width of blade (or Flow length) and the number of blade layout.
Drift eliminator is very important. When processing water is balance, the optimum setting of flushing method affects the flushing efficiency directly (including flushing starting procedure, water pressure settings, nozzle type, layout and etc.), the flushing effect directly affects the flushing efficiency of the demister as well.
Critical flow rate is the basis of the entire flue gas desulfurization process to caculate the minimum efficiency of eliminator. optimize the design to minimize the project cost; demister operating at critical flow rate conditions, Water load, easy to carry with water secondarily.
