Description
Technical field
This utility model belongs to fume treatment technical field, and be specifically related to a kind of flue gas desulfurization sewage recycles processing means.
Background technology
Desulfurization after burning, also known as flue gas desulfurization, refer to remove the sulfur in flue gas and the process of compound, in prior art, the method for flue gas desulfurization is sulfur-containing smoke gas boiler combustion produced, being entered high-efficient desulfation dust-extraction device by bottom tangential direction from bottom, after the liquid film formed through the spraying of spiral board and shower nozzle contacts, (carbon black) liquid collecting of being caught absorbs, sour gas is absorbed by sodium hydroxide solution, and after purification, waste gas is from desulfation dust-extraction device chimney breast high-altitude qualified discharge.Liquid after desulfation dust-extraction device absorbs, flows through neutralization pond voluntarily, fully reacts under the effect of eddy flow inertia, finally precipitates its mud and impurity, periodic cleaning in sedimentation tank, and the clear liquid after filtration enters alkali liquor pond (regulation PH), again recycles.But find in production practices, only the sewage after desulfurization and dedusting is processed with a neutralization pond due to general, if dirty impurities in water is more, such neutralization pond precipitation filter effect is bad, cannot obtain clear liquid after filtration, and filter sordid sewage and enter alkali liquor pond when recycling, the desulfurization and dedusting effect of flue gas can be affected, so can bring vicious cycle, affect the operational effect of wet type desulfurizing dust collector, the flue gas making discharge does not reaches discharge standard, and then pollutes environment.
Utility model content
For deficiencies of the prior art, the technical problems to be solved in the utility model is that the sewage after making flue gas desulfurization is effectively filtered and precipitates, it is thus achieved that relatively clean clear liquid enters alkali liquor pond and carries out comprehensive cyclic utilization again.
nullFor achieving the above object，This utility model use following technical proposals: a kind of flue gas desulfurization sewage recycle processing means，Including Industrial Boiler、Wet type desulfurizing dust collector、Neutralization pond、Alkali liquor pond、Alkali liquid tank and desulfurization aqueous alkali pipe，The flue gas of described Industrial Boiler enters wet type desulfurizing dust collector by chimney intake,The sidewall of described wet type desulfurizing dust collector is provided with sparge pipe，The described alkali liquor in alkali liquid tank enters alkali liquor pond by mending alkali pipe，Described alkali liquor pond is connected with desulfurization aqueous alkali pipe with delivery pump by circulation drinking-water pipe，Described desulfurization aqueous alkali pipe is connected with the sparge pipe of wet type desulfurizing dust collector，It is characterized in that: described neutralization pond is made up of single filter sedimentation tank and cascade filtration sedimentation tank，It is provided with composite filter bottom described single filter sedimentation tank and cascade filtration sedimentation tank，Composite filter is made up of the palmae bark of lower floor and the cobblestone on upper strata,Described single filter sedimentation tank is crossed the mouth of a river by one-level and is connected with cascade filtration sedimentation tank，Described cascade filtration sedimentation tank is crossed the mouth of a river by two grades and is connected with alkali liquor pond，The desulfurization water of described wet type desulfurizing dust collector enters single filter sedimentation tank by gutter.
It is additionally provided with tap water filling pipe on desulfurization aqueous alkali pipe described in the utility model.
Compared with prior art, the beneficial effects of the utility model have: owing to neutralization pond is made up of single filter sedimentation tank and cascade filtration sedimentation tank, and it is provided with the filter course by palmae bark and cobblestone bottom single filter sedimentation tank and cascade filtration sedimentation tank, so by cobblestone and the synthetic filter effect of palmae bark, the impurity in sewage after energy active adsorption flue gas desulfurization, the impurity content making the clear liquid in entrance alkali liquor pond reduces, enhance the desulfurization and dedusting effect of wet type desulfurizing dust collector, it is ensured that flue gas after treatment meets environmental emission standard.
