Description
Technical field
The utility model relates to a kind of fume treatment desulfurization bubble tower.
Background technology
The pernicious gases such as the sulfur dioxide in flue gas produced when fire coal, fuel oil, combustion gas, nitrogen oxide enter air, cause acid rain, destroy ecological environment, affect the healthy of people.For the more strict control control criterion that China proposes the permission concentration of emission of sulfur dioxide in flue gas, nitrogen oxide about environmental regulation, various flue gas desulfurization technique method and apparatus arises at the historic moment.Desulfurizer, as the critical component of recirculating fluidized bed flue gas purifying technique, directly affects the desulfuration efficiency of a whole set of desulphurization system.Traditional desulfurizer complex structure, complex operation, desulfurized effect is poor, and production efficiency is low, and service life is short simultaneously, needs often maintenance and renewal part, adds production cost.
Utility model content
For the problems referred to above, the utility model proposes a kind of fume treatment desulfurization bubble tower.
For solving this technical problem, the utility model takes following scheme: a kind of fume treatment desulfurization bubble tower, comprises tower body and Ta Gai, and described tower body Lower Half is set to water tank; Be provided with the inlet manifold that flue gas enters above described water tank, inlet manifold offer multiple air inlet branch road entered below liquid level; Described water tank sidewall offers the inlet entered for limestone slurry and the discharging opening of discharging for calcium plaster, and inlet is positioned at above discharging opening; Described water tank is built-in with agitator, is provided with the air hose passing into air in water tank, air hose offers multiple gas outlet for bubbling; Described tower body sidewall offers pure qi (oxygen) outlet, and pure qi (oxygen) outlet is positioned at above inlet manifold.
Further, described air hose is positioned at below discharging opening.
Further, described discharging opening goes out to be provided with blowoff valve.
Further, described tower cap surface is provided with safety valve.
Further, described agitator is dasher.

Detailed description of the invention
Now with specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
Disclose a kind of fume treatment desulfurization bubble tower with reference to figure 1 the present embodiment, comprise tower body 1 and Ta Gai 2, tower body 1 Lower Half is set to water tank; Be provided with the inlet manifold 3 that flue gas enters above described water tank, inlet manifold 3 offer multiple air inlet branch road 4 entered below liquid level; Water tank sidewall offers the inlet 9 entered for limestone slurry and the discharging opening 8 of discharging for calcium plaster, and inlet 9 is positioned at above discharging opening 8; Water tank is built-in with agitator 7, is provided with the air hose 5 passing into air in water tank, air hose 5 offers multiple gas outlet 6 for bubbling; Tower body 1 sidewall offers pure qi (oxygen) outlet 10, and pure qi (oxygen) outlet 10 is positioned at above inlet manifold 3.
Air hose 5 is positioned at below discharging opening 8; Discharging opening 8 goes out to be provided with blowoff valve; Tower lid 2 surface is provided with safety valve 11; Agitator 7 is dasher.
