At present, wet desulfurization technology is widely used for controlling the emission of polluted gas in a thermal power plant, but a great amount of liquid drops can be carried after flue gas is treated by a desulfurization absorption tower, so that not only part of desulfurization equipment is corroded, but also the environment nearby the thermal power plant is adversely affected, and therefore, a demister is arranged in a desulfurization system in most thermal power plants, so that the liquid drops carried in the flue gas are reduced, and the performance of the demister has a direct influence on the reliability of the wet desulfurization technology.

The existing demister basically adopts a blade baffling separation technology, and can separate gas and liquid according to different inertias of gas and liquid phases. When the mist-containing air flow enters the channel of the baffle blades, the flowing direction of the air flow changes along with the change of the channel direction among the baffle blades. When the channel direction between the baffle blades is changed, the gas-liquid two-phase inertia is different due to the difference of the density and the mass of liquid drops carried in the gas flow and the gas, so that the movement direction of the liquid drops is easier to change than the direction of the gas flow, the liquid drops can strike the surfaces of the baffle blades and adhere to the surfaces to form a water film, after the water film is gathered to a certain amount, the water film can drop under the action of gravity and flow into a bottom container, the gas continues to move to the next stage, and the gas-liquid separation is completed.
