The wire mesh demister is composed of two parts: a gas-liquid filter mesh pad (composed of several mesh blocks) and a support. The mesh block is composed of several layers of flat corrugated wire mesh, grilles and distance rods.
There are four types of gas-liquid filters used in wire mesh demisters, namely SP, DP, HP and HR. When customers place an order with our company, they should specify which type of gas-liquid filter to use.
Common materials for wire mesh demisters: 304, 304L, 321, 316L, NS-80, nickel wire, titanium wire, monel alloy, Hastelloy alloy, polytetrafluoroethylene PTFE (F4), F46, polypropylene (PP), and various fiber materials.
Brand types: S30403, S30408, S31603S, S31608, S32168, S31008, S31803, etc.
1. Metals: various brands of stainless steel wire, aluminum alloy wire, monel wire, incoloy, pure titanium wire, pure nickel wire, phosphor bronze wire, copper wire, brass wire, galvanized iron wire, etc.
2. Non-metallic: polytetrafluoroethylene (PTFE) wire (F4), polyfluoroethylene propylene (FEP) wire (F46), polyvinylidene fluoride (PVDF) wire (F2), polypropylene wire (PP), polyethylene wire (PE), polyvinyl chloride wire (PVC), etc.
Interweaving of metal wire and non-metal wire: stainless steel and glass fiber mixed, etc.;
Wire diameter: 0.10mm-0.55mm
Weaving: Knitting weaving, can be divided into single-strand weaving, double-strand weaving, multi-strand weaving, etc.
Mesh surface: flat mesh surface and corrugated mesh surface (corrugated width and depth have different specifications)
Specifications: Standard type: hg5-1404-81 (riser type) hg5-1405-81 (reduced diameter type) hg5-1406-81 (full diameter type)
Diameter: 300MM-15000MM
Thickness: 100MM-800MM
The operating gas velocity of the wire mesh demister is the speed at which the gas passes through the wire mesh. The operating gas velocity should be selected appropriately. If the operating gas velocity is too low, the inertia of the mist in the gas is too small and the mist is in a floating state. When passing through the wire mesh layer, the mist floats in the wire mesh and cannot be completely removed; if the operating gas velocity is too high, the accumulated droplets are not easy to fall from the wire mesh, and the liquid fills the wire mesh, causing the collected droplets to splash again and be entrained by the gas, causing liquid flooding, thereby reducing the defoaming efficiency.
The wire mesh demister is very efficient. For mist particles with a diameter of more than 5um, the capture efficiency is 98%~99.99%, while the pressure drop of the gas passing through the demister is very small (250~500Pa), which is unmatched by various other gas-liquid separation devices. It has played a great role in my country's chemical, petroleum and other industries for many years.
Wire mesh demisters are widely used in industries such as chemical, petroleum, sulfuric acid, medicine, light industry, metallurgy, machinery, construction, aviation, shipping, environmental protection, etc. They are also widely used in various tower equipment such as vacuum towers, absorption towers, separation tanks, gas separators, compression absorption tanks, evaporators, washing towers, distillation towers, recovery containers, dust collection devices, etc.
Several main forms of wire mesh demister are introduced as follows:
1. Riser type wire mesh demister: The riser type wire mesh demister is installed at the lower end of the riser at the top of the equipment.
2. Reduced diameter wire mesh demister: When the diameter of the designed wire mesh demister is smaller than the diameter of the drum equipment, a short section needs to be added during installation, which is called a reduced diameter wire mesh demister. It is divided into top-mounted and bottom-mounted types.
3. Full-diameter wire mesh demister: When the designed wire mesh demister diameter is equal to the diameter of the cylinder equipment, the demister is directly installed in the cylinder, which is called a full-diameter wire mesh demister. It is also divided into top-mounted and bottom-mounted types.
Wire mesh demister structure: Wire mesh demister is mainly composed of wire mesh, wire mesh grid to form wire mesh block and support device for fixing wire mesh block. Wire mesh is a gas-liquid filter mesh made of various materials, and the gas-liquid filter mesh is composed of metal wire or non-metal wire. The non-metal wire of the gas-liquid filter mesh is twisted from multiple strands of non-metallic fibers, or it can be a single strand of non-metallic wire. The wire mesh demister can not only filter out larger liquid foam suspended in the airflow, but also filter out smaller and tiny liquid foam, and is widely used in gas-liquid separation devices in chemical, petroleum, tower manufacturing, pressure vessels and other industries.
Features: 1. Simple structure and light weight
2. Large porosity and small pressure drop
3. Large contact surface area and high defoaming efficiency
4. Easy to install, operate and maintain
5. Long service life
Performance: High and low temperature resistance, acid and alkali corrosion resistance.
Application: Wire mesh demister (also known as wire mesh demister, foam catcher) is a highly efficient gas-liquid separation device, widely used in chemical, petroleum, sulfuric acid, medicine, light industry, metallurgy, machinery, construction, aviation, shipping, environmental protection and other industries. The ethylene, synthetic ammonia, chemical fiber and other production equipment introduced from abroad in my country also use wire mesh demister as a gas-liquid separation device.
