Abstract
The utility model discloses a desulfurizing tower second grade absorbing device has absorption tower body that absorption tower entry and absorption tower exported, sprays layer, porous distributor, defroster, its characterized in that: the absorption tower body include still that the one -level sprays reaction zone, transition district, second grade tympanic bulla reaction zone and absorption tower thick liquid pond four regions in the district, the one -level spray reaction zone, second grade tympanic bulla for the reaction zone baffle separate, the one -level that sets up in the absorption tower promptly sprays reaction zone and second grade tympanic bulla reaction zone two -stage absorbing structure, has combined the advantage of two kinds of desulfurization techniques, makes the desulfurization efficiency on this absorption tower can reach more than 99%, and the dust collection efficiency can reach more than 85%.
Description
Technical field
The utility model relates to a kind of desulfuration absorbing tower absorption plant, and more specifically it is a kind of desulfurizing tower sponge oil unit.
Background technology
In the evolution of flue gas desulfurization technique, bubble tower and spray column are two kinds of turriforms comparatively advanced in wet limestone-gypsum FGD technique, and they have respective pluses and minuses.On the one hand, be that gas phase is highly dispersed in liquid phase during bubble tower gas-liquid contact, there is larger gas liquid interfacial area, heat transfer and mass-transfer efficiency higher, and be by solution dispersion in gas phase during spray column gas-liquid contact, actual gas liquid interfacial area is less, and mass-transfer efficiency is little relative to bubble tower; On the other hand flue gas in a liquid bubbling time have the effect of similar water film dedusting, therefore bubble tower is to the better effects if of flue gas ash removal, especially the dust effect to less than 1 μm is more obvious, in addition, bubble tower system due to mass transfer effect good, can run at low ph values, be generally 3.5-4.5, low ph value is conducive to the crystallization of gypsum.
Utility model content
For solving above technical problem, the purpose of this utility model in order to overcome the weak point of above-mentioned background technology, and provides a kind of desulfurizing tower sponge oil unit two kinds of technology combined.
To achieve these goals, the technical solution of the utility model is such: comprise the absorption tower body with absorption tower entrance and absorption tower outlet, described absorption tower body also comprises one-level spray reaction zone, secondary blistering reaction district, and described one-level spray reaction zone, secondary blistering reaction are separated by dividing plate between district;
Described one-level spray reaction zone comprises absorption tower entrance, porous distributor, spraying layer, and described porous distributor is installed between absorption tower entrance and spraying layer.Described spraying layer is positioned at absorption tower entrance top;
Described secondary blistering reaction district comprises smoke distribution room, air jet pipe, absorption tower outlet, and air jet pipe is positioned at bottom, smoke distribution room, and absorption tower outlet is positioned at bottom, smoke distribution room.
In technique scheme, described porous distributor is installed between two-layer spraying layer, and described spraying layer is three to six layers.
In technique scheme, flue dust enters secondary blistering reaction district again and absorbs after one-level spray reaction zone absorbs.
The beneficial effects of the utility model are: by sponge oil unit, and namely one-level adopts spray reaction, and secondary adopts blistering reaction, can improve desulfuration efficiency and efficiency of dust collection.

Detailed description of the invention
Describe the utility model performance in detail below in conjunction with accompanying drawing, but they do not form to restriction of the present utility model, only for example, simultaneously by illustrating that advantage of the present utility model will become clearly and easy understand.
As shown in FIG. 1 to 3, desulfurizing tower sponge oil unit, comprise the absorption tower body 2 with absorption tower entrance 1 and absorption tower outlet 8, described absorption tower body 2 also comprises one-level spray reaction zone I, secondary blistering reaction district II, is separated between described one-level spray reaction zone I, secondary blistering reaction district II by dividing plate 5;
Described one-level spray reaction zone I comprises absorption tower entrance 1, porous distributor 3, spraying layer 4, and described porous distributor 3 is installed between absorption tower entrance 1 and spraying layer 4.Described spraying layer 4 is positioned at above absorption tower entrance 1;
Described secondary blistering reaction district II comprises smoke distribution room 6, air jet pipe 7, absorption tower outlet 8, and air jet pipe 7 is positioned at bottom, smoke distribution room 6, and absorption tower outlet 8 is positioned at bottom, smoke distribution room 6.
Described porous distributor 3 is installed between two-layer spraying layer 4, and described spraying layer 4 is three to six layers.
Flue dust enters secondary blistering reaction district II again and absorbs after one-level spray reaction zone I absorbs.
As shown in Fig. 4 ~ Fig. 5, for adopting the desulfurizing tower overall structure of sponge oil unit, desulfurizing tower sponge oil unit is positioned at the middle part of desulfurizing tower, and this device bottom is stock tank district, absorption tower, and top is flue gas transition region.
Unspecifiedly be prior art.
