Description
Technical Field
The invention belongs to the technical field of flue gas desulfurization, and particularly relates to a demister blade and a demister.
Background
Demisters are important components of desulfurization absorber towers. The demister is arranged above the absorption tower and mainly used for separating entrained liquid drops and slurry in the flue gas, so that the mist drops are prevented from entering a chimney and being discharged into the atmosphere. The working mechanism is as follows: mist drops carried in the flue gas pass through the demister at a certain speed, and due to the inertia effect, the mist drops strike the demister blades and are trapped, and when more and more mist drops are trapped, the mist drops fall down after reaching a certain weight and enter the desulfurizing tower again.
Conventional baffle mist eliminators include flat plate mist eliminators and ridge mist eliminators, in which mist droplets having a particle size of greater than 40 μm can be removed, with a droplet removal rate of only 50% for mist droplets having a particle size of 20 to 40 μm, and a lower mist removal rate for mist droplets having a particle size of less than 20 μm.
After mist droplets are captured by the demister, when the flow speed of flue gas is too high or the demister is seriously blocked, the mist droplets can be secondarily entrained by the flue gas to reenter the flue gas, so that the escape rate of the mist droplets is increased, the demisting efficiency is affected, and the common demister does not have a water collecting function.
