Beneficial effects of the present invention are：
1. liquid is more readily formed in cyclone cylinder after the anti-release apparatus of the droplet based on conial ring shape is employed in the present invention
Film：Because multistage double cyclone dedusting demisters are that droplet and dust are caught using the liquid film in cyclone cylinder, increase by first
After circular cone ring and the second circular cone ring, there is certain barrier effect to the liquid film in cyclone cylinder so that liquid film is not easy by cyclone cylinder
Interior rotary gas is smashed, thus liquid film more continuous uniform；
2. reducing droplet escape, dust removing effects are improved：After cyclone tube inner surface sets circular cone ring, to cyclone tube inner surface
Liquid film serves barrier effect, is relatively not provided with for the smooth cyclone cylinder of the first circular cone ring and the second circular cone ring, forms liquid film
Droplet is not easy to take away cyclone cylinder surface by the flue gas that cyclone cylinder internal rotation rises.Meanwhile after liquid film reaches certain thickness, due to
Action of Gravity Field can voluntarily flow downward；
3. the setting of the first annulus and the second annulus, further enhance the first circular cone ring and the second circular cone ring prevents mist
The effect of escape is dripped, the droplet that the setting of circular ring structure is easy to be blocked flows, further increased straight down along annulus
Dust removing effects.
