Product structure:
Wire mesh demister is mainly composed of wire mesh block and supporting device for fixing wire mesh block. Wire mesh is air-liquid filter screen made of various materials. Air-liquid filter screen is composed of metal wire or non-metal wire The non-metallic wire of the gas-liquid filter screen is twisted from multiple non-metallic fibers and can also be a single non-metallic wire The mesh demister can not only filter the larger liquid foam suspended in the airflow, but also filter the smaller and tiny 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 (demister) is used to separate droplets entrained by gas in the tower to ensure mass transfer efficiency, reduce valuable material loss and improve the operation of compressor behind the tower. Generally, wire mesh demister is set at the top of the tower 3-5um droplets can be effectively removed. If demister is installed between trays, it can not only ensure the mass transfer efficiency of trays, but also reduce the distance between trays Therefore, the screen 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 such as radio wave interference Now it has been widely used in environmental protection industrial production of chemical industry, petroleum, sulfuric acid medicine, light industry, metallurgical machinery
How it works:
When the gas with mist rises through the mesh at a certain speed, the mist collides with the mesh filament and is attached to the filament surface due to the inertia of mist rising Diffusion of mist on the surface of filament the gravity settlement of mist makes mist form large droplets and flow along the filament to the junction of two filaments Wettability of filaments the surface tension of liquid and the capillary action of filaments make the droplets larger and larger until the droplets gather so large that the gravity generated by them exceeds the combined force of the lifting force of gas and the surface tension of liquid that the droplets separate and fall from the filaments After passing through the mesh demister, the gas basically contains no mist Separate the mist in the gas to improve the operating conditions, optimize the process index, reduce the corrosion of equipment, prolong the service life of equipment, increase the treatment capacity, recover valuable materials, protect the environment and reduce air pollution, etc. Simple structure, small volume, high defoaming efficiency, small resistance, light weight, easy installation, operation and maintenance. The net defoamer has a collection efficiency of 98%-99.8% for mist whose particle size is ≥ 3 ~ 5um, but the pressure drop of gas passing through the defoamer is very small, only 250-500Pa, which is beneficial to improve the production efficiency of the equipment
