Description
Technical field
The utility model is related to coal-burning power plant treating tail gas field, is a kind of wet desulfuration tower specifically.
Background technology
Big-and-middle-sized coal-burning power plant of China carries out SO using wet desulfurization of flue gas by limestone-gypsum method device mostly2Absorption take off
Remove.With the further raising of environmental emission standard, the potentiality lifting of wet desulphurization device is also difficult all the more, and consumes energy and occupy height
Under not.
The short slab of existing wet desulfuration tower generally existing is flow field inequality caused by smoke inlet arrangement form.Pending cigarette
From in the slightly downward-sloping inflow tower of entrance level of wet desulfuration tower middle and lower part side, mainstream gas are rushed at gas under effect of inertia
Turned round upwards after the tower wall of offside, form smoke inlet to the flow of flue gas path of offside tower wall, dotted line part as shown in Figure 3
Point, flowed out from the exhanst gas outlet of tower top after flowing through spraying layer and demister layer.The inhomogeneities of above-mentioned flowing is wet desulphurization
The tower flue gas flow rate of half side relative with smoke inlet is higher, and the flue gas flow rate of opposite side is relatively low, correspondingly desulfurized effect
Just height is uneven.Flow irregularity has become the key factor that restriction desulfuration efficiency is further improved.
The traditional arrangement form of wet desulfuration tower spraying layer is sprayed along wet desulfuration tower different height arranging multiplayer level
Layer, its spraying effect is generally speaking uniform on the level cross-sectionn of wet desulfuration tower, but due to cigarette in wet desulfuration tower
Air-flow field uniformity is poor, therefore slurries spray there is a problem of coordinating not good with flow of flue gas.
To improve flow field uniformity, the representational technology path of a class is to increase current equalizer.Such as Application No.
201420538554.2 utility model patent discloses the turbulence device that a kind of wet desulphurization puies forward effect, and scheme is：It is rapid including one
Turbosphere pipeline more than fluid layer, including two-layer；The turbosphere pipeline includes the pipe of some parallel arrangements；Also including will be described
Turbosphere pipeline is fixed on some articulated stands and some support beams in absorption tower；The turbosphere pipeline is put down between layers
Row interlaced arrangement.And for example the utility model patent of Application No. 201020289859.6 discloses a kind of rotation remittance coupling desulfurization dedusting
Device, scheme is：Including at least one through support member in absorption tower is arranged on, be provided with described support member to
Few one layer of eddy flow collector-shoe gear.Both the disadvantage is that, the kinetic energy rejection of inlet flue gas is larger, device crushing is higher.
In order to be realized with alap energy consumption " minimum discharge " of pollutant, it is impossible to rely on traditional raising liquid merely again
Gas than more extensive technology path, and must be from the key technique seeking breakthrough for limiting current sulfur removal technology efficiency.
