Corrosion Resistant Vane Mist Extractor For Water Film Spray Tower 180 Resistant

Production Description

Pvc mist eliminator A demister is a device often fitted to vapor-liquid separator vessels to enhance the removal of liquid droplets entrained in a vapor stream. Demisters may be a mesh type coalescer, vane pack or other structure intended to aggregate the mist into droplets that are heavy enough to separate from the vapor stream.

Demisters can reduce the residence time required to separate a given liquid droplet size thereby reducing the volume and associated cost of separator equipment. Demisters are often used where vapor quality is important in regard to entrained liquids particularly where separator equipment costs are high (e.g., high pressure systems) or where space or weight savings are advantageous.

Operating Principle

When gas containing entrainment passes through the mist eliminator in a certain speed , the entrainment collides with corrugated plate and attaches on the surface of corrugated plate due to the inertial impact of gas. The spread and gravity sedimentation of the entrainment on the surface of corrugated plate make it produce large droplets. Droplets flow to the turning of corrugated plate in direction of airflow. Droplets become larger and larger due to centrifugal force and its effect with corrugated plate ( including friction effect and adsorption effect ) as well as the surface tension of the liquid. They can be separated from the surface of the corrugated plate until their gravity goes beyond total of upward force and liquid surface tension force. The multi-fold structure of corrugated plate increases the chances of chasing entrainment. The remaining entrainment will be chased under the same effect at the next corner. This repetitive process enhances efficiency of demisting. Basically, there is no entrainment in gas after going through mist eliminator.
