Customization Wire Mesh Demister Filter Element

Product Specification

Mesh mist eliminators or pads are made by knitting wire, metal, or plastic into tightly packed layers, which are then crimped and stacked to achieve the required pad thickness.

Mesh pads remove liquid droplets by impingement of droplets onto the wires, followed by coalescence into droplets large enough to disengage from the bottom of the pad and drop through the rising gas flow into the liquid holding part of the separator. The prominent mechanism for droplet capture is inertial impaction. The capture efficiency for a conventional mesh mist eliminator, at a given droplet size, is a function of the wire or fiber total thickness, mesh density, and wire diameter, as well as the properties of the fluids to be separate more efficient.

Wire mesh demister is mainly composed of wire mesh, wire mesh grid, wire mesh block and supporting device for fixing wire mesh block. The wire mesh is a gas-liquid filter of various materials, and the gas-liquid filter is composed of metal wire or non-metal wire. The non-metallic wire of the gas-liquid filter screen is twisted by multiple strands of non-metallic fibers, and can also be a single strand of non-metallic wire. The wire mesh demister can not only filter the large liquid foam suspended in the air flow, but also filter the small and micro liquid foam. It is widely used in gas-liquid separation devices in chemical industry, petroleum, tower manufacturing, pressure vessel and other industries.

Wire mesh demister can be made of various materials, depending on its use, and its major materials are as per the below:

1). SUS302, SUS304, SUS304L, SUS316, SUS316L, SUS321, SUS309, SUS310S, SUS202, NS-80.

2). Monel, nickel, titanium.

3). Plastic (PP, PC,PE,PVC,PTFE).

4). Mild Steel (plain and galvanized).

5). Nylon yarn and glass fiber.

6).Aluminium, copper and brass.

What is the treatment of organic wastewater by knitted mesh demister?

1.Organic wastewater has many kinds, high toxicity, complex components, high chroma and strong acidity and alkalinity. Therefore, not all organic wastewater can be treated by resin adsorption method, or only by resin adsorption method can be discharged up to the standard. However, it often needs to be combined with other treatment methods for hierarchical treatment to achieve satisfactory results.
2.The strength and durability of the adsorption resin need to be improved so that it can be used continuously for 4-5 years, further improving the performance-price ratio of the macroporous resin.
3.The treatment process of organic wastewater by macroporous resin adsorption method is relatively complex, so it is necessary to further simplify the process, and recycle or completely harmless treat the organics desorbed from the resin to reduce environmental pollution.
4.At present, the demister pads use macroporous adsorption resin to treat waste water, and mostly uses the stacked adsorption column structure. Multiple parallel and reversing adsorption beds should be used to replace the adsorption column structure, further strengthening the standard of adsorption equipment and adsorption resin, and creating conditions for the popularization and application of this technology.
In short, before the treatment of organic wastewater, it is necessary to carry out specific, comprehensive analysis and in-depth and detailed research on each kind of wastewater, and then formulate effective, economic and feasible treatment methods and process routes. If the resin adsorption method can not make the high concentration organic wastewater meet the discharge standard, the resin adsorption method can be used to reduce the concentration, and then other processes can be used for subsequent advanced treatment with good results.
