The flue gas distributing device of an absorption tower has the main structure that an air inlet inclined downwards is arranged on a tower body, and the cross section of the air inlet forms a circular shape; at least three flow guiding plates are arranged in the tower body and are orderly and mutually staggered and distributed on the air inlet flow direction of the air inlet. After an absorption tower uses the flue gas distributing device of the structure, flue gas entering the absorption tower can be uniformly diffused and equally distributed, and has equalized flow velocity, therefore the flue gas can be sufficiently and effectively contacted with slurry so that the utility model enhances desulfurizing efficiency.
Description
Technical field
The utility model relates to and is used for fire coal boiler fume is carried out the desulphurization system that desulfurization is handled, and refers more particularly to the flue gas distributor on the absorption tower in this desulphurization system.
Background technology
In the desulphurization system of fire coal boiler fume being carried out the desulfurization processing, the absorption tower is one of them pith, the main effect on absorption tower is: pending flue gas is introduced the absorption tower from the absorption tower air inlet, flue gas moves in the absorption tower from lower to upper, with spray the slurries reverse movement that gets off from the absorption tower top jet nozzle, and fully contact, slurries effectively adsorb the sulfur-bearing composition in the flue gas, and the flue gas after desulfurization is then discharged from the top, absorption tower.From the above mentioned as can be known, obtain desulfurized effect preferably, flue gas is contacted fully effectively with slurries, therefore must control the flow regime of flue gas, flue gas can evenly be spread and the flow velocity equilibrium in the absorption tower.Its air inlet cross section of absorption tower commonly used at present is a rectangle, and downward-sloping certain angle, in the absorption tower, there is no the flue gas distributor, its shortcoming is: because air-flow is the gas column form in rectangular air inlet, it is strong to have the center, the flow behavior that the edge is weak, adding overdraught enters in the tower body not through shunting from air inlet, therefore flue gas can not get good diffusion in the absorption tower, its cross section is power and does not wait state in the process of moving upward, thereby also just can not with spray the slurries that get off from nozzle and carry out fully effectively contacting, just be difficult to reach good adsorption effect, thereby also just be difficult to realize higher desulfuration efficiency.
Summary of the invention
At the problems referred to above, the utility model will provide a kind of flue gas distributor that is used for the absorption tower, use this device equably flue gas to be dispersed in the absorption tower, thereby can realize higher desulfuration efficiency.
The technical solution adopted in the utility model is: the flue gas distributor in the described absorption tower, and its structure mainly comprises: tower body is provided with downward-sloping air inlet; The cross section of air inlet is circular, is provided with at least three deflectors in tower body, and deflector is in staggered distribution successively mutually on the air intake airflow direction of air inlet.
The further technical scheme of the utility model is: deflector staggers on the air intake airflow direction that is evenly distributed in air inlet successively mutually, and the last a slice deflector on being positioned at the air intake airflow direction, all the other deflectors are the semi-round ring shape plate.
A kind of further technical scheme of the utility model is: along on the air intake airflow direction, the radius of semi-round ring shape deflector progressively successively decreases.
The utility model another kind further technical scheme is: the last a slice deflector that is positioned on the air intake airflow direction is a circular slab.
The utility model has the advantages that: after in the absorption tower, having used flue gas distributor described in the utility model, can make that the flue gas that enters in the absorption tower evenly spreads, equivalent distributes and the flow velocity equilibrium, thereby flue gas can be contacted fully effectively with slurries, improved desulfuration efficiency greatly.

Embodiment
Below in conjunction with the drawings and specific embodiments technical scheme described in the utility model and operation principle thereof and advantage are further described.
As shown in Figure 1 and Figure 2, the flue gas distributor in the absorption tower described in the utility model, its structure mainly comprises: tower body 1 is provided with downward-sloping air inlet 2; The cross section of air inlet 2 is circular, in tower body 1, be provided with at least three deflectors---be provided with five deflectors 31,32,33,34,35 in the present embodiment altogether, these five deflectors stagger on the air intake airflow direction that is evenly distributed in air inlet 2 successively mutually, and the last a slice deflector 35 on being positioned at the air intake airflow direction, all the other deflectors 31,32,33,34 are the semi-round ring shape plate---and their shape can be referring to Fig. 3, shown in Figure 4, and the radius of semi-round ring shape plate successively decreases successively; And the last a slice deflector 35 that is positioned on the air intake airflow direction is that circular slab---its shape can be referring to shown in Figure 5.In the present embodiment, the mounting means of deflector is: five deflectors are all hung be installed on the cross bar 4, cross bar 4 is fixedly installed in the tower body 1.
The operation principle of the flue gas distributor of said structure is: after pending flue gas was introduced in the tower body 1 from air inlet 2, because of the cross section of air inlet 2 is circular, thereby flue gas was the multi-layer annular air-flow, and it is more even to distribute; In tower body 1, air-flow can move ahead along the air intake airflow direction of air inlet 2, and along with moving ahead of air-flow, the part air-flow is dammed by first semi-round ring shape deflector 31, trapped flue gas slowly rises under the effect of 31 guiding of first deflector and tower body 1 upper area negative pressure; Remaining air-flow then continues to move ahead along the air intake airflow direction of air inlet 2, meet and dammed until partial fume and second semi-round ring shape deflector 32, trapped partial fume slowly rises under the effect of 32 guiding of second deflector and tower body 1 upper area negative pressure; Remaining exhaust gas volumn is then respectively successively through the damming of the 3rd, the 4th, the 5th deflector, and under the suction function of the guiding of each sheet deflector and absorption tower upper area, slowly rises.So far, the exhaust gas volumn that enters in the tower body 1 from air inlet 2 has obtained good diffusion, and slowly rise with laminar condition, evenly with along and in an orderly manner with spray the slurries that get off from the absorption tower top jet nozzle and contact fully effectively and adsorption reaction takes place, thereby reduced the resistance that is produced when flue gas penetrates slurry layer to the full extent, avoid partial fume with fully effectively absorption and escaping of slurries, thereby obtain best desulfurized effect.In actual use, the big or small available following mode of every deflector is determined: promptly: the flow area that every deflector is held back is equivalent to long-pending N/one of whole air intake flow area of air inlet 2, and wherein N is the sum of the deflector in the tower body 1; And the quantity of deflector can be determined according to actual operating positions such as the size on absorption tower and flue gas stream.
From the above mentioned as can be known, after in the absorption tower, having used flue gas distributor described in the utility model, can make that the flue gas that enters in the absorption tower evenly spreads, equivalent distributes and the flow velocity equilibrium, thereby flue gas can be contacted fully effectively with slurries, improved desulfuration efficiency greatly.
