Description
Technical field
The present invention relates to a kind of method of flue gas desulfurization, more particularly, especially a kind of stable desulfurizing tower energy-conservation again and fume desulphurization method.
Background technology
Along with socioeconomic high speed development, the flue gas of generation gets more and more, containing a large amount of SO in flue gas
2deng sour gas, if be directly discharged in air, the generation of acid rain can be caused, so desulfurization process must be carried out to flue gas before discharging.Adopt gas, the reverse mode of colliding of liquid substantially in current industry, flue gas enters from desulfurizing tower bottom, three layers of downward opening spiral nozzle are arranged on top, every one deck carries desulfurizing agent by a high-lift acid-proof pump, high pressure desulfurizing agent by spiral nozzle time by high speed atomisation, the flue gas come with bottom fully mixes, and reaches the object of desulfurization.But this method needs to configure One's name is legion, expensive spiral nozzle, and in order to reach good atomizing effect, the energy consumption that the pressure loss causes also is very considerable; Key is the essence of desulfurization is that acid-base neutralization generates water-fast sulfate, because desulfurizing agent recycles, causes spiral nozzle fouling and clogging and wearing and tearing, and desulfurizing agent atomization conditions worsen, the reduction of desulfurizing tower desulfuration efficiency even cannot work.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the invention provides a kind of gas-liquid mixed fully, reduce equipment cost and stable desulfurizing tower energy-conservation again and by the method for this desulfurizing tower to flue gas desulfurization.
Technical scheme of the present invention is achieved in that a kind of stable desulfurizing tower energy-conservation again, comprise tower body, described tower body upper end is provided with gas approach, it is characterized in that, described gas approach side is provided with desulfurizing agent import, mixing arrangement is provided with in described tower body, described mixing arrangement is provided with conical part, this conical part is erected on bracing frame, funnel component is provided with below described conical part, be fixed in tower body by support bar outside described funnel component, described tower body lower end is provided with desulfurizing agent outlet, below this tower body, side is connected with chimney by exhanst gas outlet, demister is provided with in described chimney, demister cleaning device is provided with above described demister.
In above-mentioned a kind of stable desulfurizing tower energy-conservation again, be provided with steady rest in described conical part, described steady rest is connected with bracing frame.
In above-mentioned a kind of stable desulfurizing tower energy-conservation again, described mixing arrangement is at least provided with three.
The present invention also provides a kind of method of flue gas desulfurization, the method of this flue gas desulfurization in circulation stock tank, extracts desulfurizing agent with an acid-proof pump to enter desulfurizing tower top, flue gas also enters from desulfurizing tower top simultaneously, desulfurizing agent and flue gas is made naturally to flow to mixing arrangement downwards, under the repeatedly dispersion and collision effect of conical part and funnel component, continuous change flow velocity and flow direction, extend the time of staying of gas liquid mixture in desulfurizing tower, make gas-liquid fully be atomized mixing, make acid-base neutralization react more abundant.
In the method for above-mentioned flue gas desulfurization, described desulfurizing agent is normal temperature limewash.
In the method for above-mentioned flue gas desulfurization, described flue-gas temperature is 80 ~ 105 DEG C.
Beneficial effect of the present invention is: only in circulatory pool, extracting desulfurizing agent with one instead of three acid-proof pumps enters desulfurizing tower top, and flue gas can automatically fully mix with desulfurizing agent flow process in desulfurizing tower and produce multiple impacts, gas liquid mixture is fully atomized, without the need to configuring spiral nozzle, decrease equipment investment, also reduce energy consumption.
