The stainless steel wire mesh demister is a gas-liquid separation device. The gas passes throughthe wire pad of the demister , which is resistant to corrosion by weak corrosive media such as air, steam, and water, and chemically corrosive media such as acids, alkalis, and salts. It is also called stainless acid-resistant steel. The stainless steel wire mesh demister is one of the most widely used materials, with the characteristics of corrosion resistance, low cost, easy installation, and long service life.
1.Structure: The wire mesh demister is mainly composed of a wire mesh, a wire mesh grid, a wire mesh block, and a supporting device for fixing the wire mesh block. The wire mesh is a gas-liquid filter made 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 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. It is widely used in gas-liquid separation devices in the chemical, petroleum, tower manufacturing, pressure vessels and other industries.

4. Working principle: When the gas with mist rises at a certain speed through the wire mesh, due to the inertia of the rising mist, the mist collides with the wire mesh filaments and is attached to the surface of the filaments. The diffusion of the mist on the surface of the filaments and the gravity sedimentation of the mist make the mist form larger droplets that flow along the filaments to the intersection of the two filaments. The wettability of the filaments, the surface tension of the liquid and the capillary action of the filaments make the droplets larger and larger until the aggregated droplets are so large that the gravity generated by themselves exceeds the combined force of the rising force of the gas and the surface tension of the liquid, and the droplets separate and fall from the filaments. After the gas passes through the wire mesh demister, it basically does not contain mist. Separating the mist in the gas can improve the operating conditions, optimize the process indicators, reduce equipment corrosion, extend the service life of the equipment, increase the processing capacity and recover valuable materials, protect the environment, and reduce air pollution. The structure is simple and the volume is small, the defoaming efficiency is high, the resistance is small, the weight is light, and the installation, operation and maintenance are convenient. The wire mesh defoamer can capture 98%-99.8% of the mist with a particle size of ≥3~5um, and the pressure drop of the gas passing through the defoamer is very small, only 250-500Pa, which is conducive to improving the production efficiency of the equipment.
5. Application: Stainless steel wire mesh demister is used to separate the droplets entrained by the gas in the tower to ensure the mass transfer efficiency, reduce the loss of valuable materials and improve the operation of the compressor after the tower. Generally, the wire mesh demister is installed on the top of the tower. It can effectively remove the droplets of 3--5um. If the demister is installed between the tower plates, it can not only ensure the mass transfer efficiency of the tower plates, but also reduce the distance between the plates. Therefore, the wire mesh demister is mainly used for gas-liquid separation. It can also be used as an air filter for gas separation. In addition, the wire mesh can also be used as a buffer for various instruments in the instrument industry to prevent electronic shielding devices from radio wave interference. It is now widely used in industrial production of chemical, petroleum, sulfuric acid, medicine, light industry, metallurgy, machinery, and environmental protection.
