Description
Technical field
The present invention relates to flue gas desulfur device, particularly relate to a kind of seawater and biological method flue gas desulfurization denitrification integrated device.
Background technology
SO in industrial smoke
2and NO
xthe pollution caused is the subject matter of current atmospheric environment, directly restricts harmonious economy stable development, harm humans life health.Through people's effort over a long time, at SO
2reduction of discharging aspect has achieved preliminary effect.But the air pollution situation of sternness does not obtain the change of essence.Along with the raising of countries in the world people's environmental consciousness, also increasingly strict about air environmental protection legislation in international community, people remove SO in the urgent need to studying the technology made new advances simultaneously
2and NO
x.At present, severe reduction of discharging situation is all faced with at some large industrial smoke discharge industry such as electric power, cement, metallurgy, boats and ships etc.In power industry, some coal unit build desulfurizing tower and denitrating tower respectively, and not only a construction cost is high, and it is comparatively large to maintain operating cost, namely utilize existing technology carry out the construction of flue gas desulfurization and denitrification device and transform the very high financial cost of needs.Therefore, a kind of new and effective denitration integrated device is studied very necessary.
In the method for desulphurization denitration, biological method purification technology is low with its cost, efficiency is high, the feature of non-secondary pollution and have good application prospect.Existing flue gas biological method purification technology is based on denitration, researcher proposes multi-form biological denitrification tower building method, in these methods, the overwhelming majority is all conceived to how to improve denitration efficiency, citation form is all in different spaces simple superposition by two or more identical biologic packing material, repeatedly purify, expect the raising carrying out implementation efficiency according to this.But, nitrogen oxide in flue gas mainly exists with the form being insoluble in the NO of water, NO is difficult to enter into liquid phase medium, and the adsorption capacity of antimicrobial surface is also very low, NO is also just difficult to contact with living beings, cannot effectively carry out biochemical reaction with microorganism and transform, make the actual purification efficiency of NO very low.In addition in bioanalysis desulfurization and denitrification integral, also there is researcher to propose to cultivate two kinds of bacterium colonies of desulfurization and denitration in same culture medium simultaneously, but two kinds of different bacterium colonies for the physicochemical property such as temperature, PH and nutraceutical requirement generally different, thus cause being difficult to make denitrification efficiency reach the highest simultaneously.Also studies have found that, when amount of sulfur contenting in smoke is too high, be easy to cause bacterial classification poisoning and lost efficacy.And current certain methods needed extra flue gas cooling device before carrying out bio-absorbable, so that energy consumption is higher even there is secondary pollution.
Meanwhile, sea water desulfuration technology has the advantages such as raw material is inexpensive, technique is simple, reliable.Power plant in coastal area, steel plant and large ship fume treatment problem, can introduce sea water desulfuration technology.Find in theory calculate and practical application, if merely rely on seawater desulfurization device by the SO2 process in flue gas to more than 90%, the seawater amount of needs is huge.In addition, the seawater containing unstable salt that Sea water respiratory distress syndrome needs larger aeration tank process to discharge, this just makes at boats and ships and does not have the factory of larger space to use seawater method limitation.Although it can thus be appreciated that traditional seawater desulfurizing process is applied, the seawater consumption existed is large, absorption tower filler price used and consume large, and the problems such as system operation cost is high still can not be ignored.
