Abstract
A combined flue gas dedusting, denitration and desulfurization integrated apparatus comprises a reaction tower, wherein the lower part of the reaction tower is provided with a flue gas inlet passage, the upper part of the reaction tower is provided with a clean flue gas outlet, a denitration catalyst, an ammonia inlet and a desulfurization sprinkler are arranged sequentially from the top down in the reaction tower, a mechanical dust collector and a deflector are sequentially arranged in the flue gas inlet passage, and a flow equalizer is arranged between the denitration catalyst and the ammonia inlet. The utility model integrates the dedusting, denitration and desulfurization of flue gas together, the structure and the technique are simple, the occupied floor area is small, the operation cost is low, and the apparatus is environment-friendly.
Description
Technical field
The utility model relates to a kind of assembled smoke gas dedusting, denitration, desulfurization integrated device.
Background technology
China's Energy Mix is based on coal, and high medium sulphur coal, oil occupy suitable ratio in power fuel.The atmosphere pollution that produces behind the coal combustion mainly contains sulfur dioxide, nitrogen oxide, flue dust (pellet) and as the carbon dioxide of greenhouse gases; under the situation of national economy sustained, stable growth, the aggravation of contradictions of energy exploitation and application and environmental protection.According to statistics, SO2 whole nation discharge capacity was about 2,990 ten thousand tons in 2008, about 1,870 ten thousand tons of NOx discharge capacity, and the acid rain region area expands to more than 35%.These years, the smoke pollution discharge capacity sharply increases, and brings enormous economic loss to national economy, also the heavy damage environment for human survival.Simultaneously since the coal commonly used of China to have in high ash and the ash calcium content big, so in the design of denitration, desulfurizer, also need to be equipped with the fume dust remover of the high grey feature of adaptation.Therefore, in order to satisfy more and more strict emission control standards, the dedusting of flue gas, denitration, desulfurization finally are indispensable.
The utility model content
In view of above-mentioned weak point, the purpose of this utility model is to provide a kind of structure and technology comparatively simple, and floor space is little, and operating cost is low, environmental friendliness, collection flue gas ash removal, denitration, desulfurization are assembled smoke gas dedusting, denitration, the desulfurization integrated device of one.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of assembled smoke gas dedusting, denitration, desulfurization integrated device, comprise reaction tower, wherein, be provided with fume inlet passage and reaction tower top in the reaction tower bottom and be provided with clean cigarette outlet, be disposed with denitration catalyst device, ammonia import and desulfurization spray thrower in the reaction tower from top to down, be provided with mechanical dust collector and deflector in the described fume inlet passage successively, between described denitration catalyst device and the ammonia import current equalizer is installed.
Flue gas enters before the reaction tower, carry out dedusting through the mechanical dust collector in the fume inlet passage earlier, through deflector flue gas is evenly distributed in the reaction tower then and touches reactive desulfurizing agent with the desulfurization spray thrower, flue gas after the desulfurization mixes by current equalizer with ammonia again, ammonia fully contacts with nitrogen oxide in the flue gas, enters the catalyst layer complete reaction in the denitration catalyst device again.
The beneficial effects of the utility model are: the utility model collection flue gas ash removal, denitration, desulfurization is an one, structure and technology are comparatively simple, floor space is little, operating cost is low, environmental friendliness, be provided with mechanical dust collector in the reaction tower fume inlet passage and can reduce flying dust to the obstruction of desulfurization spray thrower nozzle and to the influence of denitration catalyst device catalyst, the deflector that is provided with in the fume inlet passage makes flue gas evenly arrange in reaction tower so simultaneously, can fully react with desulfurization spray thrower hydrojet, make desulfuration efficiency higher, and be arranged on current equalizer between denitration catalyst device and the ammonia import, ammonia is mixed in flue gas, ammonia fully contacts with nitrogen oxide in the flue gas, enters the catalyst layer complete reaction again, and the denitration rate is up to more than 80%.
