When the gas containing mist flows through the demister at a certain speed, due to the inertial induction of the gas, the mist collides with the demister blades (due to streamline deflection) and the accumulated mist is large enough to generate itself. When the gravity of the liquid exceeds the combined force of the rising force of air pressure and surface tension, the mist is separated from the surface of the blade. The multi-fold structure of the demister blade increases the chance of mist capture. The air pressure that continues to be carried away is captured by the same action at the next corner. This repeated action greatly improves the defogging efficiency. After the gas passes through the demister, the mist is basically eliminated. The flue gas passes through the arc-shaped channel of the demister, and is entrained, adsorbed and separated from the exhaust gas under the action of inertial force and gravity; the flue gas after desulfurization flows through the demister at a certain level, and the flue gas is continuously changed in the direction of movement. Due to the action of centrifugal force and inertia, the mist droplets in the flue gas are inhaled and collected on the demister blades. The mist droplets gather into a captured water flow. Due to the action of gravity, they fall into the slurry pool, achieving gas-liquid separation, making the flow through the demister It is relieved after the smoke from the fogger reaches the defogging requirements.

Vane mist eliminators are physical separating devices that work on the principle of inertial impaction. Vanes, sometimes called chevrons, are parallel corrugated sheets held at a fixed distance apart to create a sinuous flow path for mist laden gas. As the mist laden gas flows through the vane, at every change in the direction the droplet tends to move in a straighter line than the bulk of gas. The captured droplets coalesce on the vane, forming larger drops which subsequently trickles down. Depending upon the operating conditions and physical properties of gas & liquid, typical droplet separation ranges from 10 µm to 40 µm.

 

Advantages of vane mist eliminator:

• High gas & liquid handling capacity
• Low pressure drop
• Rugged construction
• Wide variety of materials
• Resistant to fouling
• Easy to clean
• Pocketed and non-pocket design
