Titanium mesh demister 


The gas-liquid filter and support device used in the manufacture of the wire mesh demister are produced by our factory according to the standard of the Ministry of Chemical Industry HG/T21618-1998 wire mesh demister .The wire mesh demister produced by our factory can not only filter out the large liquid foam suspended in the airflow, but also filter out small and tiny liquid foam. It is widely used in chemical, petroleum, tower manufacturing, pressure vessel and other industries. In the gas-liquid separation device.


Product Description: 

Titanium is a very active metal with a low equilibrium potential and a high tendency to thermodynamically corrode in the medium. In practice, however, titanium is very stable in many media, such as titanium, which is resistant to corrosion in media such as oxidizing, neutral, and weakly reducing. This is because titanium and oxygen have a great affinity. In the air or in an oxygen-containing medium, a dense, highly adherent and inert oxide film is formed on the surface of the titanium to protect the titanium substrate from corrosion. Even if it is mechanically worn, it will heal quickly or regenerate. This indicates that titanium is a metal with a strong tendency to passivate. An oxide film of titanium having a medium temperature below 315 ° C always maintains this property. Industrial pure titanium includes GR1, GR2, GR12 and other grades.


The diameter of the dispersed droplets in the gas encountered in normal chemical operations is about 0.1 to 5000 μm. Generally, the particles having a particle diameter of 100 μm or more are easily settled due to the rapid sedimentation rate. Generally, droplets larger than 50 μm in diameter can be separated by gravity sedimentation; droplets above 5 μm can be used for inertial collision and centrifugal separation; for smaller droplets, try to aggregate them to form larger particles, or use fiber filters and Electrostatic defogger. The wire mesh demister is mainly used for separating droplets having a diameter of more than 3 μm to 5 μm.


When the misty gas rises at a certain speed and passes through the wire mesh placed on the grille, the mist collides with the filament and adheres to the surface of the filament due to the inertia of the rising mist. The mist on the surface of the filament is further diffused and the gravity of the mist itself settles, causing the mist to form larger droplets along the filament to its interlacing. Due to the wettability of the filament, the surface tension of the liquid, and the capillary action of the filament, the droplet is made larger and larger, until its own gravity exceeds the combined force of the buoyancy of the gas and the surface tension of the liquid, and is separated and falls. Flow to the downstream equipment of the container. As long as the conditions such as the operating gas velocity are properly selected, the defoaming efficiency of the gas after passing through the wire mesh demister can reach 97% or more, and the purpose of completely removing the mist can be achieved. 



The wire mesh demister is selected from the top-loading type and the bottom-loading type wire mesh demister: when the position of the hole is opened on the top of the wire mesh demister, or when there is no hole in the hole, the top-loading type wire mesh is selected. when the hole is opened under the wire mesh demister, the bottom-loading wire mesh demister is selected.
