Detailed description of the invention
The present invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of dusty gas scrubbing tower, including waters washing part and tower tray washing part, waters is washed
Part is positioned at the lower section of tower tray washing part；Described waters washing part includes dusty gas entrance 4, air inlet pipe 10, pond, waters 2
And point bubble device 3 of segmentation bubble, pond, waters 2 is positioned at the bottom of scrubbing tower, and point bubble device 3 is arranged at the lower section of pond, waters 2 liquid level,
Dusty gas entrance 4 is positioned at pond, waters 2 ullage, and air inlet pipe 10 one end connects dusty gas entrance 4, and the other end extends to point
Bubble device 3 lower end；Described tower tray washing part includes washing water inlet 6, bubble cap tray 1 and the descending liquid guiding current to flow downward
Pipe 9, bubble cap tray 1 is provided with 4 layers, and washing water inlet 6 is positioned at the top of bubble cap tray 1, and pond, waters 2 is positioned at bubble cap tray 1
Lower section, downspout 9 is arranged at the end of every layer of bubble cap tray 1；Clean gas outlet 5, Heisui River circulation port 7 it is additionally provided with on scrubbing tower
With black water discharge mouth 8, clean gas outlet 5 is positioned at tower top center, and Heisui River circulation port 7 is positioned at bottom tower body on sidewall, and Heisui River is arranged
Put mouth 8 and be positioned at Ta Di center.
In the present embodiment, a point bubble device 3 is stratified and set on around air inlet pipe 10, and the number of plies is 3-4 layer, and adjacent two layers divides bubble device 3
Distance be 50-70ccm.
In the present embodiment, point bubble device 3 is made up of at grade multiple points of parallel the fixing of bubble bar, as in figure 2 it is shown, point bubble
Being machined with point bubble protruding 11 of serrated irregular shape on bar, point bubble protruding 11 is towards wash tower bottoms.
