Description
Technical Field
The utility model relates to the technical field of, especially, relate to a torrent increase in efficiency device for flue gas wet flue gas desulfurization.
Background
Under increasingly strict environmental protection requirements of China, the S02 index of the smelting flue gas desulfurization tail gas emission is executed according to a special emission limit value (SO 2 is less than or equal to 100 mg/Nm) in many areas, and even the S02 index is higher than the index standard. The absorption tower is an apparatus or a structure for physically or chemically removing harmful gases such as SO2 in flue gas. The main working process of the spray absorption tower is that absorption slurry is conveyed to a spray layer formed by a plurality of nozzles by a slurry circulating pump, the absorption slurry is sprayed out by atomizing nozzles of the spray layer to form an intensive atomized slurry spray area, the slurry is contacted with flue gas in the atomized spray area to absorb harmful gases such as SO2 in the flue gas, the flue gas desulfurization is completed, and the slurry flows along the inside of the absorption tower and falls into a slurry pool at the bottom of the absorption tower. Most of spraying equipment of the spraying type desulfurizing tower directly sprays absorption liquid to fall down, and gaps exist among water curtains, so that efficient reaction is difficult to carry out.
Disclosure of Invention
An object of the utility model is to prior art not enough, and provide a torrent increase device for flue gas wet flue gas desulfurization, its flue gas entry top increases the torrent increase device in the wet flue gas desulfurization tower for flue gas air distribution effect in improving current wet flue gas desulfurization spray column improves desulfurization efficiency and equipment operating stability.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a torrent increase device for flue gas wet flue gas desulfurization, includes urceolus and inner tube, the urceolus with both ends opening hollow structure about the inner tube is, the urceolus with be provided with a plurality of blades between the inner tube, every the blade with the interior circumference of urceolus is tangent, every the blade all is provided with certain angle of inclination, the urceolus with the inner tube passes through the blade is fixed.
Preferably, the inclination angle is 45 degrees.
Preferably, the inner cylinder, the outer cylinder and the blades are all made of 316L stainless steel.
The utility model has the advantages that: the utility model provides a torrent increase in efficiency device for flue gas wet flue gas desulfurization, passes through as the flue gas the utility model discloses before mixing with the fountain thick liquid, the flue gas is owing to receive the restriction of runner, and velocity direction and size change. The original vertical flow is changed into horizontal rotating flow. Meanwhile, as the flow cross section is greatly reduced, the flow velocity of the flue gas is sharply increased and is increased from the original several meters per second to dozens of meters per second, the dynamic pressure head is greatly increased, meanwhile, the flue gas is divided into dozens of airflow which rotationally flows at high speed under the action of the rotating blades, when the flue gas meets the desulfurization circulating liquid, the airflow quickly disperses and breaks the liquid phase and fully mixes the airflow to form powerful pneumatic stirring, and the gas phase and the liquid phase form a foam layer, so that the specific surface area of the gas phase and the liquid phase is expanded to the maximum. Gas-liquid two phases are subjected to very thorough and rapid mass transfer in the foam layer, so that the desulfurization efficiency is improved.

Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1, the turbulence synergistic device for wet flue gas desulfurization of the present embodiment is disposed at a high position of about 500mm above a flue gas inlet of a wet desulfurization tower, and a mounting plate is disposed at the high position for mounting and fixing, the utility model discloses a whole body is made of 316L stainless steel, including an outer cylinder 1 and an inner cylinder 2, the outer cylinder 1 and the inner cylinder 2 are both upper and lower openings, an inner hollow structure, the outer cylinder 1 adopts a 4mm reel pipe, generally 8 blades are uniformly arranged along the inner circumference of the outer cylinder 1, each blade inclination angle is generally designed to be 45 °, and different angles can be made according to the viscosity degree of the desulfurization slurry; wherein 4 alternate blades are welded and fixed with the inner wall of the outer barrel, and the other 4 blades are welded and fixed with the adjacent blades and the inner barrel. Further, the blade comprises a first blade 3 and a second blade 4, and the second blade 4 is an L-shaped blade.
Further, when the viscosity degree of the desulfurization slurry is small, the number of the blades uniformly distributed along the inner circumference of the outer cylinder 1 may be designed to be 10 or 12, as required.
The working principle is as follows: when the flue gas passes through the device, the impact force of the flue gas drives the blades to rotate, the flue gas is limited by the flow channel, the speed direction and the size are changed, the flue gas is changed from the original vertical flow into the horizontal rotating flow, meanwhile, the flow cross section area is greatly reduced, the flow speed of the flue gas is sharply increased and is increased to dozens of meters/second from the original meters/second, the dynamic pressure head is greatly increased, meanwhile, the flue gas is divided into dozens of airflow in high-speed rotating flow under the action of the blades, when the flue gas meets the desulfurization circulating liquid, the airflow rapidly disperses and smashes the liquid phase and fully mixes the liquid phase to form powerful pneumatic stirring, the gas-liquid two phases form a foam layer, and the specific surface area of the. Gas-liquid two phases are subjected to very thorough and rapid mass transfer in the foam layer, so that the desulfurization efficiency is improved.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
