Product Specification

Coarse prefilter wire mesh filter material with stainless steel frame
 
 
1.General introduction of wire mesh demister

The wire mesh demister is used to collect the liquid particles contained in the vapor phase after boiling, vacuum evaporation or bubbling.
The small droplets in the gas contact with the wide surface of the filament of the mesh demister, gradually grow into large droplets, and flow and drop through a special structure to accelerate the condensation of the droplets. The mesh mat of the demister is highly porous, so the steam gas passes through the demister unimpeded, leaving only pure gas.
This process is not a kind of filtration, because the aperture of the woven mesh has no special relationship with the size of the droplets. This demisting is caused by the collision and sudden change caused by the flow velocity of small droplets, and the condensation and gravity of droplets cause their decline.
This is a process of combining mechanical and physical phenomena.

2. Design of Wire Mesh Demister.

2.1 general
A. XXX project specification - vessel specifies size, style, thickness, configuration and material.
B. The type of demister is defined as follows:
C. Type G is a mesh blanket with variable weaving density. The density of steam inlet is the lowest, and that of outlet is the highest. Typical inlet / outlet knitted mesh densities are 5 lb/ft3 (80.1) and 9 lb/ft3 (144.2). Customers can request variable density blankets with slightly different weaving density and wire diameter.
Type V shall be determined by the supplier according to the process conditions provided by the customer. The supplier can determine the type of demister that is most suitable to meet the demist requirements. The selected style may include grid pads, blades, or a combination of grid and blades. The demister can be oriented vertically, horizontally or at an angle determined by the supplier. Single pads of variable knitting density may also be used.
2.2 construction
A. The demister shall be fabricated as a whole or as the minimum number of sections required to be inserted into the vessel manhole.
B. The mesh gasket shall closely cooperate with the gasket sealing system.
C. The thickness of mesh bedding shall not exceed 9 inches (230 mm). If more than one layer is required, the joints shall be staggered.
D. The integrated circular mesh pad can be spiral.
2.3 supports and gratings
A. In addition to the customer's requirements, the general layout of the demister support and grille shall comply with the factory practice.
B. The mist eliminator supplier can also provide final details of the mist eliminator support and compression grille.
C. The demister supplier shall provide details of the components attached to the vessel to the vessel manufacturer in a timely manner for installation without changing the vessel manufacturing progress.

D. Each part of the mesh mat shall include a grid on each side.

E. G-type mesh mats shall be provided with inlet and outlet rigid welded gratings. The outlet grille and blanket outlet area of the G-type mesh mat shall be clearly marked with "outlet".

F. Spiral mesh mats shall include an x-mesh on both sides.

2.4 fastening device

As a mist eliminator manufacturer, we can provide ties or other devices to fix the mist eliminator part to the bracket, connect the grille to its container bracket, and fix the layers together if multiple layers of mist eliminators are required.
