The Working Principle of Demister Pad

The working principle of industrial DEMISTER PAD is mainly based on the inertia, collision and separation of liquid droplets. When the gas containing foam flows through the DEMISTER PAD, the speed of the gas will slow, resulting in a collision between the droplet and the PAD surface. These collisions transformed the kinetic energy of the droplet into a momentum and contacted it with the PAD surface.

With the movement of liquid droplets on PAD, they may be fused into larger droplets. These large droplets eventually became large enough to overcome the rising force of the airflow on them, thereby falling back to the droplet collector. In this process, the droplets in the gas are captured and separated, thereby achieving the effect of degradation.

Specifically, its working principle can be divided into the following steps:

Gas inflow: Gas fluid (usually contains suspended droplets or atomized liquid droplets) into Demister Pad through the import pipe.

Dripping collision: Inside the PAD, the speed of gas is slowing down. The collision between the droplet and the PAD surface makes it turn into a momentum, and the droplet begins to slide or move along the PAD surface.

Drop fusion and separation: With the movement of liquid droplets on PAD, they may be fused into larger droplets. Large droplets eventually became large enough to overcome the raising force of the airflow on them, thereby falling back to the droplet collector.

Clean gas emissions: After PAD treatment, most of the droplets in the gas have been captured and separated. The remaining gas becomes dry and clean, and can be discharged from exports to the atmosphere, and no visible atomized liquid droplets are no longer included.

It should be noted that different types of DEMISTER PAD may be different in specific working principles, but in general, the purpose of degradation through similar processes.

In addition, the performance and efficiency of PAD are also affected by various factors, such as gas flow velocity, droplet particle size, structure and material of PAD. In practical applications, you need to choose the appropriate Demister Pad according to the specific conditions and requirements, and make reasonable design and installation.
