丝网除雾器

Mesh pad is a structured packing component used in demisters and mist eliminators to separate liquid droplets from gas streams through impaction and coalescence.

技术定义与适配语境

A mesh pad is a critical component in demister/mist eliminator systems, consisting of multiple layers of knitted or woven metal or plastic wires arranged in a specific pattern to create a tortuous path for gas flow. It functions by capturing fine liquid droplets (typically 3-50 microns) through inertial impaction, direct interception, and Brownian diffusion mechanisms, allowing the coalesced liquid to drain while permitting clean gas to pass through.

定义
A mesh pad is a critical component in demister/mist eliminator systems, consisting of multiple layers of knitted or woven metal or plastic wires arranged in a specific pattern to create a tortuous path for gas flow. It functions by capturing fine liquid droplets (typically 3-50 microns) through inertial impaction, direct interception, and Brownian diffusion mechanisms, allowing the coalesced liquid to drain while permitting clean gas to pass through.
工作原理
The working principle involves three main mechanisms: 1) Inertial impaction - larger droplets cannot follow gas streamlines and impact wire surfaces; 2) Direct interception - droplets following streamlines contact wire surfaces; 3) Brownian diffusion - smallest particles diffuse to wire surfaces. Captured droplets coalesce into larger droplets that drain by gravity.

常见问题

What is the typical efficiency range for industrial mesh pads?

Industrial mesh pads typically achieve 99.5-99.9% efficiency for droplets larger than 3 microns, with efficiency decreasing for sub-micron particles where additional filtration stages may be required.

How do you determine the appropriate mesh pad thickness?

Pad thickness is determined by required efficiency, gas velocity, liquid loading, and pressure drop constraints. Thicker pads (200-300mm) provide higher efficiency but increase pressure drop and cost.

What maintenance is required for mesh pads?

Regular inspection for fouling, corrosion, or physical damage; periodic cleaning with compatible solvents or steam; replacement when efficiency drops below design specifications or pressure drop exceeds allowable limits.
