The utility model content
The purpose of this utility model is, a kind of flue gas desulfurization column in series treating apparatus is provided, and it can effectively remove sulfur in smoke and sulfur trioxide, and it is simple to have a device structure, advantage of low manufacturing cost.
The technical solution of the utility model: a kind of flue gas desulfurization column in series treating apparatus, comprise A absorption tower, B absorption tower and flue, the top on A absorption tower is connected by the middle part of flue with the B absorption tower.In the desulphurization plant transformation project, use the mode of this double-column in series, the old absorption tower of both need not having dismantled, can simplify the internal structure on new absorption tower again, make the desulphurization plant transformation project not only save improvement cost but also made full use of old resource, and the flue gas after the improved equipment desulfurization can also reach national specified discharge standard.
In the aforesaid flue gas desulfurization column in series treating apparatus, the A absorption tower comprises housing one, smoke inlet one, exhanst gas outlet one, agitator one, oxidation fan one and circulating pump one, smoke inlet one is located at the middle part of housing one, top in the housing one is provided with spray equipment one, spray equipment one is connected by the end of circulating line one with the circulating pump one of being located at housing one bottom, the other end of circulating pump is connected by the liquid outlet one of pipeline with housing one bottom, the bottom of housing one also is provided with oxidation fan and agitator one, and exhanst gas outlet one is located at the top of housing one and is connected with flue.
In the aforesaid flue gas desulfurization column in series treating apparatus, the B absorption tower comprises housing two, smoke inlet two, exhanst gas outlet two, circulating pump two, agitator two, oxidation fan two and demister, smoke inlet two is located at the middle part of housing two and is connected with flue, circulating pump two, agitator two and oxidation fan two all are located at the bottom of housing two, one end of circulating pump two is connected with liquid outlet two on the housing two by pipeline, the other end is connected with the spray equipment two of housing two internal upper parts by circulating line two, exhanst gas outlet two is located at the top of housing two, is provided with demister between exhanst gas outlet two and the spray equipment two.The effect of demister is the SO that removes in the flue gas
3And droplet.
Compared with prior art, the utility model is cascaded two desulfurizing towers, reaches national specified discharge standard after making flue gas desulfurization.Particularly in the desulphurization plant transformation project of using sulphur coal power plant, original desulfurizing tower need not to dismantle, only needing that the preliminary treatment absorption tower of connecting is again transformed on former absorption tower a little gets final product, can either make flue gas after the processing reach discharge standard and can make full use of existing equipment again, save improvement cost.
