Description
Technical Field
The utility model belongs to a boiler tail gas processing apparatus, in particular to high-efficient whirl desulfurizing tower.
Background
In a plant using fossil fuel as an energy source, flue gas containing a large amount of harmful acidic gases such as fly ash and SO 2 is generally discharged during the production process, and sulfur, dust and flue gas in the flue gas need to be removed by a desulfurizing tower. At present, the atmospheric pollutants in flue waste gas are usually removed by wet desulphurization, namely, a plurality of desulphurization solution spraying layers are arranged on the upper part of a desulphurization tower, flue gas enters the lower part of the tower body arranged by a flue gas input pipeline, the flue gas enters the spraying desulphurization tower through the lower part of the tower body, and the flue gas is mixed and reacted with the desulphurization solution sprayed out of the desulphurization solution spraying layers in the spraying desulphurization tower in the rising process of the flue gas to realize desulphurization, so that the emission standard is met, and the pollution degree to the environment is reduced. The problem that this kind of desulfurizing tower exists is that, the flue gas enters into the desulfurizing tower from the flue gas import after, and the distribution is uneven, can rise fast at the middle part of desulfurizing tower, so, flue gas and doctor solution mixed reaction are abundant inadequately, and desulfurization efficiency is low, and is with high costs, and especially when the sulfur dioxide content in the flue gas is 5000mg/Nm 3, even higher, desulfurization efficiency is very low, causes very big pollution to the environment.
Disclosure of Invention
The to-be-solved technical problem of the utility model is, overcome the not enough of above-mentioned prior art existence, provide a high-efficient whirl desulfurizing tower, make flue gas evenly distributed and rotatory rising through flue gas disturbance device, at the in-process flue gas that rises and doctor solution intensive mixing reaction to improve desulfurization efficiency.
The utility model discloses there is a tower body, there is flue gas outlet duct at the top of tower body, there is on the upper portion of tower body to spray the layer, in spray the layer and spray the layer down, there is the flue gas intake pipe in the lower part side of tower body, there is the desulfurization liquid pond in the lower part of tower body, there is the discharge port bottom in the desulfurization liquid pond, its special character is, there is flue gas disturbance device in the lower part of tower body, the higher authority of flue gas intake pipe, the flue gas is evenly distributed and rotatory the rising in the tower body behind the flue gas disturbance device, makes flue gas and desulfurization liquid intensive mixing reaction, thereby improves desulfurization efficiency, flue gas disturbance device have a circular flat board, have a plurality of vortex body on circular flat board, the vortex body constitute by drum and a plurality of vortex blade, the even distribution of vortex blade changes the flow state of flue gas through the vortex blade in the drum.
The turbulence blades are spiral, so that the smoke is changed from vertical rising to spiral rising, and the spiral rising smoke in each turbulence body interacts with each other to form airflow which is uniformly distributed and rises in a rotating mode.
The utility model has the advantages of, set up flue gas disturbance device in the lower part of tower body, the higher authority of flue gas intake pipe, flue gas disturbance device's circular flat board has blocked the passageway that the flue gas rises, forces the flue gas evenly distributed below circular flat board, then vortex spiral shell screwing in through disturbing the fluid rises, and spiral shell screwing in rises's flue gas interact again in each disturbance fluid, form stable, the equipartition, rotatory ascending air current, at the in-process flue gas that rises and doctor solution intensive mixing reaction to desulfurization efficiency has been improved.
