Description

Wire mesh demister with composite multilayer defoaming function

Technical Field

The utility model relates to a silk screen demister technical field especially relates to a silk screen demister that compound multilayer defoamed.

Background

The wire mesh demister is a high-efficiency gas-liquid separation device and is widely used in petroleum, chemical industry and other industries. Fog, foam, droplets are generally defined in the industry by the diameter of the liquid particles, with liquid particles <10 μm in diameter called fog; liquid particles with a diameter of 10 to 1000 μm are called foam; liquid particles >1000 μm in diameter are called droplets. Currently, two types of gas-liquid separation devices are most commonly used, namely vertical/horizontal gravity separators and vertical/horizontal wire mesh separators. The gravity separator is usually used for gas-liquid separation of liquid particles with the diameter larger than 200 mu m, and has poor separation effect on liquid particles with smaller diameter; and the wire mesh separator can effectively separate liquid particles with the diameter of more than 3-5 mu m in the gas.

The working principle of a conventional demister screen is that when gas with liquid particles rises through the screen at a certain speed, the mist collides with the screen filaments and is attached to the surfaces of the filaments due to the inertia of the rising mist. The dispersion of the mist on the surface of the filaments and the gravity settling of the mist enable the mist to form larger liquid drops and flow to the junction of the mesh filaments along the 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, and when the accumulated droplets are so large that the gravity generated by the droplets exceeds the resultant force of the rising force of the gas and the surface tension of the liquid, the droplets separate from the filaments and fall to the bottom of the container.

However, in practical application, in the process of falling, liquid drops are blown away by rising gas to form secondary entrainment and are brought back to the demister, so that the load of the demister is increased, the resistance is greatly increased, the defoaming efficiency is finally affected, and the phenomenon is more serious as the gas velocity in the tower is higher.
