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 desulfuration efficiency of wet desulfuration tower is in close relations with the mass transfer of slurry drops and flue gas.In certain scope, slurries
Drop is smaller, then specific surface area is bigger, and the mass transfer with flue gas is more efficient.And slurry drops are better with the turbulent closure scheme effect of flue gas, then
Desulfuration efficiency is also higher.
Existing wet desulfuration tower using atomizer by slurry spraying into more than particle diameter 0.5mm slurry drops, slurry drops exist
Fall in the presence of gravity and with flow flue gas adverse current, there is mass transfer and chemical reaction, realize SO in flue gas2Absorbing and removing.
Due to being limited by the factors such as nozzle performance and energy consumption, existing wet desulfuration tower must maintain high liquid-gas ratio, make a large amount of slurries repeatedly
Circulation, could so complete and SO2Contact and reaction, to reach desulfuration efficiency higher, but slurry circulating pump can be caused
A large amount of electric energy are consumed, desulfurizing tower overall operation efficiency is not high, is unfavorable for energy-saving and emission-reduction.
The utility model patent of such as Application No. 201420538554.2 discloses the turbulent flow that a kind of wet desulphurization puies forward effect
Device, scheme is：Including a turbosphere, including turbosphere pipeline more than two-layer；The turbosphere pipeline includes some parallel
The pipe of arrangement；Also include some articulated stands and some support beams that the turbosphere pipeline are fixed in absorption tower；It is described
Turbosphere pipeline is staggeredly arranged in parallel between layers.And for example the utility model patent of Application No. 201020289859.6 is disclosed
A kind of rotation converges coupling desulfurization dust arrester, and scheme is：Run through the support member being arranged in absorption tower including at least one,
Described support member is provided with least one of which eddy flow collector-shoe gear.Employed both this and arranged on cross section in desulfurizing tower
The mechanical device that liquid layer, enhancing turbulent flow and even flow fieldization are acted on is held with being formed, it has the disadvantage that the device scale of construction is larger, and brings
Extra flow of flue gas resistance is damaged, and causes air-introduced machine power consumption to increase.
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.
Utility model content
To overcome above-mentioned deficiency, effect device and a kind of wet desulfuration tower are carried the utility model proposes a kind of desulfurization, can promoted
Enter the deformation of larger slurry drops, broken and irregular movement, to improve gas-liquid mass transfer efficiency, so as to improve desulfurized effect.
In order to solve the above technical problems, the utility model is adopted the following technical scheme that：
A kind of desulfurization carries effect device, it is adaptable to wet desulfuration tower, including one or more layers generator row, every layer of generator row
Including the multiple sonic generators along wet desulphurization inner wall of tower horizontal layout.
Further, the sonic generator of each layer generator row is horizontally disposed on wet desulphurization inner wall of tower.
Further, the outlet sound mouth of the sonic generator is towards in wet desulfuration tower.
Further, the adjustable audible ripple of the sonic generator tranmitting frequency, intensity or ultrasonic wave.
A kind of wet desulfuration tower, including a smoke inlet, at least a spraying layer and an above-mentioned desulfurization carry effect device, in the cigarette
Desulfurization described in installing one on inner wall of tower between gas entrance and spraying layer carries the generator row of effect device.
Further, when the spraying layer is for multiple, desulfurization described in installation one is carried between the adjacent spraying layer of each two
Imitate the generator row of device.
Further, the desulfurization is carried effect device and is fixedly connected on inner wall of tower by welding or bolt.
Further, the desulfurization is carried effect device and is fixedly connected on inner wall of tower by a support.
The beneficial effects of the utility model are, effect device is carried to launching high-power sound in wet desulfuration tower by this desulfurization
Ripple, promotes the deformation of larger slurry drops, broken and irregular movement, so as to strengthen gas-liquid mass transfer efficiency, correspondingly takes off wet method
Sulphur tower may operate under lower liquid-gas ratio, and energy consumption is smaller and desulfuration efficiency is constant.The utility model is by sound wave to slurries
Drop is acted on, and is that contactless desulfurization carries effect device, substantially without hindrance to flow of flue gas in desulfurizing tower, therefore will not be increased and drawn
Blower fan power consumption.And, sonic generator is installed on wet desulfuration tower tower wall, and space in tower is not take up substantially, is also not directly contacted with
Slurries, therefore construct, safeguard all relatively simple.
