Chevron Mist Eliminator: Efficient Mist Elimination, Excellent Performance

Chevron mist eliminator consists of a series of parallel arranged chevron blades. This unique structure lays a solid foundation for its efficient mist elimination performance. As the gas or liquid passes through the chevron blades, tiny droplets and particles are gradually deposited and accumulated along the surface of the chevron blades. This process ensures effective separation and removal of particles. In addition, it offers excellent stability and reliability and is suitable for a wide range of industrial environments. By reducing the emission of waste and pollutants, the chevron mist eliminator also contributes to the reduction of environmental influence and meets the requirements of sustainable development.

Blade Types

Mist eliminator blades are the most basic and important components of the mist eliminator, and its performance has a crucial impact on the operation of the whole mist eliminator system. Mist eliminator blades are divided into folded type and streamlined type by their geometric shapes; and they are further divided into double-channel blades (single-peak) and triple-channel blades (double-peak).

Folded Type Blades

Folded type blade design allows the gas or liquid to undergo multiple collision retention and inertial separation as it passes through, thus promoting the deposition and condensation of tiny droplets and particles.

Streamlined Type Blades

Smooth and continuous surfaces allow fluids to pass through the blades more smoothly, and reduce turbulence and drag, which in turn lowers the velocity of droplets and particles, and allows them to sink and separate naturally. And the blades with hooks type can provide higher removal efficiency.

Working Principle

When gas containing entrainment passes through a mist eliminator at a certain velocity, due to the inertial impact of the gas, the entrainment will be attached to the surface of the mist eliminator blades.

The diffusion and gravitational settling of the entrainment on the blade surface allows the entrainment to form larger droplets and move forward with the airflow to the corner of the blade. Due to the steering centrifugal force, friction and adsorption between the mist eliminator blades, as well as the surface tension of the liquid make the droplets become larger until its gravity produced by the aggregated droplets exceeds the combined forces of gas uplift and liquid surface tension, causing the droplets to fall off.

The multi-fold structure of the chevron mist eliminator increases the chance of capturing the entrainment. The entrainment not removed is captured in the same process at the next corner, and this process repeats, which greatly improve the demisting efficiency. After passing through a chevron mist eliminator, the gas is basically free of entrainment.

Gases pass through the chevron mist eliminator and the entrainment is separated.
Application

It is is widely used in the packed columns, condensation columns, absorption columns and other equipment of chemical, petroleum, environmental protection and other industries, to remove water droplets and particles in the gas and ensure the normal operation of the equipment as well as reduce the environment pollution.
