Introduction to the materials and standards of wire mesh demister

Wire mesh demister (also known as wire mesh demister, foam catcher) is a highly efficient gas-liquid separation device
. Uses: Widely used in chemical, petroleum, sulfuric acid, medicine, light industry, metallurgy, machinery, construction, aviation, shipping, environmental protection and other industries. China's ethylene, synthetic ammonia, chemical fiber and other production equipment introduced from abroad also use wire mesh demister as a gas-liquid separation device. It is mainly used to separate droplets with a diameter greater than 3μm to 5μm.
Features: simple structure, light weight, large porosity, small pressure drop, large contact surface area, high foam removal efficiency, easy installation, operation and maintenance, and long service life.
Features of wire mesh demister:
1. Simple structure, light weight
2. Large porosity, small pressure drop
3. Large contact surface area, high foam removal efficiency
4. Easy installation, operation and maintenance
5. Long service life

The standard "HG/T21618-1998 Wire Mesh Defoamer" is revised on the basis of the original chemical industry standards HG5-1404-81, HG5-1405-81, HG5-1406-81, combined with the actual use experience of wire mesh defoamers and the advanced technology of the imported devices. The structural design of general wire mesh defoamers can be based on this standard as a reference; the technical parameters of the filter screen for wire mesh defoamers can refer to: "HT-2001 Wire Mesh Defoamer Standard", "HG/T21618-1998 Wire Mesh Defoamer Standard", "HG/T21586-1998 Drawer-type Wire Mesh Defoamer Standard". The newly revised "HG/T21618-1998 Wire Mesh Defoamer" standard has the following changes compared with the original standard:

A. Combine the original three standards into one standard for easy selection.

B. The diameter range and specifications of the demister have been adjusted, and the nominal diameter specifications have been appropriately increased.

C. The wire mesh types used in the demister are added, and the basic parameters of the wire mesh are given.

D. Increased the variety of wire mesh and grille materials.

E. Added process calculation content about wire mesh demister to facilitate selection.

This standard specifies the structure, type, specification, size, technical requirements, marking, selection and use of wire mesh demisters. This standard is applicable to gas-liquid separation devices used in vertical cylindrical equipment in the chemical, petrochemical, pharmaceutical, light industry, environmental protection and other industries. It is used to separate the mist with a droplet diameter greater than 3 to 5 μm entrained in the gas.

The specification range of wire mesh demister is: DN300～DN12000mm (non-standard products are not limited by the specification range).
