Description
Technical field
The utility model relates to a kind of gas-liquid separation device, especially relates to a kind of wire mesh demister.
Background technology
Demister belongs to gas-liquid separation device, for removing mist from gas.While containing mist in gas, can reduce the purity of this gas, such gas enters downstream unit, can affect the product quality in downstream unit; Enter atmosphere, can cause the pollution of atmosphere.
The most frequently used demister is wire mesh demister at present, and its principle is: in the time that the gas with mist rises by silk screen with certain speed, due to the effect of inertia that mist rises, mist and silk screen filament collide and be attached in filament surfaces.The gravitational settling of the diffusion of mist, mist in filament surfaces, makes the larger drop of mist formation flow to the interface point of two rhizoids along filament.The capillarity of the wettability of filament, the surface tension of liquid and filament, make drop increasing, until when the making a concerted effort of the climbing power that the gravity that the drop of assembling produces to himself greatly exceedes gas and surface tension of liquid, drop is just from filament separation whereabouts.
For example, Granted publication CN2550029Y, the Chinese patent in May 14 2003 Granted publication day discloses a kind of wire mesh demister, the silk screen piece that it is mainly made up of silk screen, silk screen grid and the supporting arrangement of fixing silk screen piece form, silk screen is mixed woven screen, mixes woven screen and is made up of wire and nonmetal wire.Its weak point is, (1) only adopts traditional silk screen filter, filters foam removal effect poor; (2), in mist during with larger drop, silk screen is easily blocked; (3) drop of small particle diameter, in the time falling, is directly taken away by air-flow again, forms reentrainment, reduces foam removal effect; (4) silk screen dismounting inconvenience.
