Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Specific embodiment 1:
See Fig. 1 and Fig. 2, the flue gas spray pre-washing device 1 of the present embodiment is arranged on fume inlet passage 2, it is characterized in that: atomizer 11 and flusher 12, described atomizer 11 and flusher 12 are located at side and the top of fume inlet passage 2 respectively, and the delivery port of described flusher 12 is right against the bottom surface of fume inlet passage 2.Described flusher 12 comprises flushing arm 13 and female pipe 14, and described flushing arm 13 is located at the top of fume inlet passage 2, and its water inlet is communicated with the delivery port of female pipe 14, and its delivery port is right against the bottom surface of fume inlet passage 2.Described flushing arm 13 is inclined and mounted on fume inlet passage 2 and the Way out rinsing arm 13 is arranged towards the outlet of fume inlet passage 2, the flusher 12 of this structure can effectively by the inside of the lime stone slurry refunds desulfuration absorbing tower 3 on the bottom surface of fume inlet passage 2 that is deposited in below atomizer 11, prevent channel blockage, ensure that flue gas can enter desulfuration absorbing tower 3 with maximum flow.
As shown in Figure 3, described atomizer 11 offers an outlet 15 and two imports 16, be interconnected between described outlet 15 and import 16, described two imports 16 steam-out (SO) and lime stone slurry respectively, steam is mixed with lime stone slurry and is sprayed by outlet 15.In the course of the work, slurries in atomizer 11 and steam meet in atomizer 11 front end, form liquid bag vaporous state, and from its outlet 15 ejection, form cloud, greatly improve the specific area of lime stone slurry, when the flue gas containing sulfur dioxide gas enters fume inlet passage 2, major part flue gas fully contacts with vaporific lime stone slurry, both dust content was reduced, make again desulfurization absorption reaction speed accelerate, achieve high-efficiency desulfurization when little liquid-vapour ratio, reduce desulfurization energy consumption.
In order to improve the contact area of lime stone slurry and flue gas substantially, thus reach the object of the most efficient and low energy consumption of desulfurization, outlet 15 injection direction of described atomizer 11 and the flue gas flow direction of fume inlet passage 2 perpendicular.
Described flusher 12 and atomizer 11 are arranged along the flue gas circulating direction order of the fume inlet passage of desulfuration absorbing tower 2.The flusher 12 of this structure is located at before atomizer 11, by timed injection, by inner for the lime stone slurry refunds desulfuration absorbing tower 3 on the bottom surface of fume inlet passage 2 that is deposited in below atomizer 11, rinse more clean and quick, improve the efficiency of flushing, thus reduce the energy consumption of desulfuration absorbing tower further.
Described flushing arm 13 and fume inlet passage 2, atomizer 11 and fume inlet passage 2, rinses arm 13 and female pipe 14 is all tightly connected.As the preferred scheme of one, in order to Fast Installation and convenient disassembly, described flushing arm 13 and fume inlet passage 2, atomizer 11 and fume inlet passage 2, rinse arm 13 and be connected by flange seal with female pipe 14.
The course of work of this flue gas spray pre-washing device is as follows: first, first open flusher 12, the former flue of desulfuration absorbing tower 2 is rinsed, by the lime stone slurry on the flue bottom surface that is deposited in below atomizer 11 towards desulfuration absorbing tower direction refunds to the inside of desulfuration absorbing tower; Then, an import 16 toward atomizer 11 passes into steam, and makes steam pressure be adjusted to 0.01MPa; Finally, another import 16 toward atomizer 11 passes into lime stone slurry, and slowly regulates the pressure raising steam, makes the lime stone slurry sprayed from the outlet 15 of atomizer 11 become cloud.
Above disclosedly be only a kind of preferred embodiment of the utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
