The specific embodiment
Referring to accompanying drawing and in conjunction with the specific embodiment, further describe the utility model, to make those skilled in the art can implement according to this with reference to description word, but be to be understood that protection domain of the present utility model is not subject to the restriction of the specific embodiment.It will be appreciated that, mentioned in following embodiment of the present utility model " on ", D score, " left side " and " right side " all take the direction shown in each figure as benchmark, these words that are used for limiting direction are only used to be convenient to explanation, do not represent the restriction to the concrete technical scheme of the utility model.
Embodiment
As shown in Figure 1, a kind of spray wet dedusting and desulfurizing tower, it comprises: sewage draining exit 1, smoke-intake pipe 2, tower body 3, clean exhanst gas outlet 4, peep hole 5, demister 6, spray district 7, supply opening 8, overfall 9, leakage fluid dram 10, liquid level gauge 11 and slurries district 12, wherein:
The top of tower body 3 is provided with clean exhanst gas outlet 4 and peep hole 5, its inside is disposed with demister 6, spray district 7 and slurries district 12 from top to bottom, and tower body 3 is provided with supply opening 8 and sewage draining exit 1 on the sidewall of slurries district 12 correspondences, the upside of supply opening 8 in slurries district 12 wherein, the downside of sewage draining exit in slurries district 12.
