Embodiment
Utilize the equipment of acidic oxide improvement aluminum oxide alkaline waste water in the smoke exhaust to comprise aluminum oxide alkaline waste water collection box 11, fog system 9, filtrating smoke dust device 18.
Aluminum oxide alkaline waste water collection box 11 is a stainless steel, and volume is 15 cubic metres, 5 millimeters of thickness.
Fog system 9 comprises filtering net 12, force (forcing) pump 13, SV 14, nozzle 16 and atomizer passgae.The working process of fog system 9 is following, and after force (forcing) pump 13 work, the aluminum oxide alkaline waste water gets into force (forcing) pump 13 through filtering net 12, and force (forcing) pump 13 adds to pressure about 1MPa,, is sprayed by nozzle 16 at last through SV 14 by atomizer passgae.
Smoke exhaust filtration unit 18 comprises smoke exhaust import 10, smoke exhaust outlet 1 and the access opening 2 that is used to overhaul; From top to bottom set gradually smoke exhaust outlet 1, access opening 2, nozzle 16 and the smoke exhaust treatment chamber 3 that includes smoke exhaust decline passway 4 and smoke exhaust rising passway 5.Smoke exhaust import 10 and smoke exhaust decline passway 4 place the central authorities of smoke exhaust treatment chamber 3, and smoke exhaust rising passway 5 places the periphery of smoke exhaust decline passway 4, is circulating water pools 6 of aluminum oxide alkaline waste water in smoke exhaust filtration unit 18 bottoms.After having adopted such structure, the workflow that the smoke exhaust of this filtration unit 18 is handled does; The circulating water pool 6-smoke exhaust rising passway 5-smoke exhaust outlet 1 of the aluminum oxide alkaline waste water of smoke exhaust import 10-smoke exhaust treatment chamber 3-fog system 9 spray-smoke exhaust decline passway 4-chimney bottom.
Sulfide among aluminum oxide alkaline waste water and the flue dust, oxynitride generation chemical action, moisture remains and accounts for leading component, and water has also played very big effect, and the moisture here refers to the moisture in the aluminum oxide alkaline waste water, need not add water in addition.The sulfurous gas that contains in the smoke exhaust, nitrogen peroxide get in the smoke exhaust treatment unit 18, and high-temperature gas runs into water and forms sulfuric acid, sulfurous acid, and nitric acid, nitrous acid and water are fallen in the circulating water pool 6 together.
Smoke exhaust filtration unit 18; As shown in Figure 2; Adopt the screen cloth barrel structure, filtering net has 15 layers, can on screen cloth, form water membrane in the course of the work; Moisture film plays the effect of filter dirt and desulfurization, and the screen cloth of formation screen cloth tube side and bottom surface can be respectively processed with any high temperature resistant, corrosion-resistant material (like stainless steel).Their aperture can be identical or different, generally is respectively 3.6mm.If the aperture is too little, then the dust in the smoke exhaust can stop up mesh, if the aperture is too big, then smoke exhaust is passed speeding up of this screen cloth tube, and sulfur limitation effect can descend.The screen cloth that constitutes screen cloth tube side and bottom surface can use diameter to process as the Stainless Steel Wire of 0.5mm and 1.0mm respectively.Manufacturing cost and erosion resistance factor are mainly considered in the selection of Stainless Steel Wire diameter.So because bottom corrosion all around selects for use thicker Stainless Steel Wire to process greatly.Top, middle part and bottom at smoke exhaust filtration unit 18 are respectively equipped with fog system 9, and each layer fog system is three rows, and each row is made up of two nozzles 16, shown in A-A sectional view among Fig. 1.Nozzle 16 adopts stainless material, aperture 1.5mm.
Fog system 9 comprises filtering net 12, force (forcing) pump 13, and SV 14, nozzle 16, filtering net 12 is main filter element with 100 purpose stainless (steel) wires, filters the impurity in the aluminum oxide alkaline waste water.Force (forcing) pump 13 adopts the horizontal corrosion-resistant water pump of pipeline force (forcing) pump BLC70/037, and this pump is horizontal topping-up pump, closed single suction formula blade wheel structure, flow 1-7m
3/ h, impeller number 1, lift 17-10m, shaft power 0.37kW.The anticorrosive SV M324969 of SV 14 employing Beijing long-range Science and Technology Ltd.s in Chinese and Western.
An induced-draught electric motor is installed at smoke exhaust import 10 places, 4 kilowatts of power, and the end of smoke exhaust import 10 can adopt bend pipe structure; As shown in Figure 2, make exhaust gas side to spraying to nozzle 16, have higher wind speed; Make smoke exhaust and spraying bump; Feasible contact is more thorough, promptly lowers aluminum oxide alkalescence, makes the smoke exhaust treatment effect obviously be superior to the structure of straight tube again.
The mean concns of sulfurous gas is 150mg/m in the smoke exhaust
3Because the size of the acidic oxide in the flue dust is merely 0.8 μ m～5 μ m; These particle suspensions have formed smog in the warm air of chimney; And the particle size of the aluminum oxide alkaline waste water that is sprayed by nozzle 16 is 3 μ m～5 μ m; When the acidic oxidation composition granule in the flue dust during less than aluminum oxide alkaline waste water spraying granule; Acidic oxidation composition granule in the flue dust is enclosed in around the aluminum oxide alkaline waste water spraying granule, and when the acidic oxide in the flue dust equaled aluminum oxide alkaline waste water particle size, the soda acid chemical action took place one to one for soot dust granule and aluminum oxide alkaline waste water particle; When the acidic oxidation composition granule in the flue dust during greater than aluminum oxide alkaline waste water particle size; The alkaline waste water spraying granule is enclosed in around the acidic oxide in the flue dust, does not carry out fully neutralization reaction with the acidic oxide particulate aluminum oxide alkaline waste water in the flue dust drips and sinks to simultaneously and go in the circulating water pool 6 thereby make, owing in the aluminum oxide alkaline waste water that sprays first, only be the skin generation soda acid chemical action at each droplet; The particle of flue dust and soda acid chemical action phenomenon does not take place in inside, thus the aluminum oxide alkaline waste water that drops in the circulating water pool still has than the highly basic chemical action.Be exactly to consider this phenomenon thereby carry out repeatedly cyclic spray in our design; The acidic oxidation composition granule that contains in the aluminum oxide alkaline waste water is successively decreased one by one, and alkalescence is successively decreased one by one, the acidic oxide that finally reaches in the flue dust is minimum; Cyclic spray five times; The composition that can reach the aluminum oxide that contains in the aluminum oxide alkaline waste water basically reduces one by one, has removed flue dust acidic oxide in the smoke exhaust again, and effect is seen table 1.
Table 1
By breadboard detected result, aluminum oxide alkalescence is about 10 to drop to 7 by PH, and the acidic oxide in the smoke exhaust obviously lowers, and the effect that reaches national examination criteria is tangible.Here point out also that aluminium manufacturer's aluminum oxide alkaline waste water is the strong basicity oxide compound, all acidic oxides in ability and the smoke exhaust play neutralization reaction.Use through the middle cooperation of flue dust acidic oxide through detecting aluminium manufacturer's waste water; PH value eases down to 7 by about 10; If higher, utilize the flue dust acid waste gas to administer the purpose of aluminium manufacturer's wastewater oxidation aluminium alkalescence up to having reached thereby then increase the round-robin number of times through detecting pH value.
In addition, what need explain is, finally being discharged to the salt compounds that all acidic oxides by in aluminium manufacturer's aluminum oxide alkaline waste water and the smoke exhaust in the circulatory pool play the neutralization reaction generation also is one type of trade effluent.It is utilized or handles by other patented technology and carry out special topic statement.The center technology of patent of the present invention only is to utilize the flue dust acid waste gas to administer the purpose of aluminium manufacturer's wastewater oxidation aluminium alkalescence.As for used equipment, also can adopt the device structure mentality of designing that has covered acidic oxide in nearly all elimination smog in the prior art.Comprise: straining installation, spraying, moisture film generation equipment, deposition or recovery system more.
