The specific embodiment
See Fig. 1 to Fig. 5, be used for the flue gas processing device of rubbish brickkiln, comprise brick bat drying chamber 28 and flue gas treatment facility, brick bat drying chamber 28 is located at the below of flue gas treatment facility, and brick bat drying chamber 28 links to each other with flue gas delivery trunk 27 from brickkiln; The flue gas treatment facility is composed in series by gas distribution facility, dry powder adsorption chamber, cyclone reaction tower 16, alkaline reaction pond 18, acid liquid reaction pond 22; Brick bat drying chamber 28 is provided with some flue gas discharge openings 1 and corresponding gas distribution flue 3 connections, flue gas discharge opening 1 and gas distribution flue 3 are provided with exhaust gas volumn regulating gate 2,4, gas distribution flue 3 is collected to main chimney flue 5 and communicates with the dry powder adsorption chamber, be provided with drystone ashes powder spraying apparatus hopper 7 and duster 6 and adsorption reaction section 9 in the dry powder adsorption chamber, be provided with master valve 8 before the adsorption reaction section 9, be provided with deep bead 10 and 150 purpose screen packs 11 in the adsorption reaction section, adsorption reaction section 9 connects the inlet 15 of cyclone reaction tower 16 by flue 12, cyclone reaction tower 16 is located on the alkaline reaction pond 18, the inlet 15 of cyclone reaction tower 16 is provided with centrifugal blower 13 and alkali lye sprayer unit 14, be provided with 150 order water smoke screen packs 17 in the tower, the top in alkaline reaction pond 18 is provided with the photosynthetic roofing layer 19 of sunlight board, the bottom is provided with pipeline 20 connections between alkaline reaction pond 18 and the acid liquid reaction pond 22, and the top is provided with ventilating opening 21; 22 tops, acid liquid reaction pond are provided with replenish air mouth 23, also are provided with gas outlet 24 and are connected with the flue gas input house steward 25 of leading to brickkiln.Two groups of layouts are adopted in adsorption reaction section 9 in this device, cyclone reaction tower 16, alkaline reaction pond 18, acid liquid reaction pond 22.
Technological process:
Hot flue gas from the rubbish brickkiln is sent into brick bat drying chamber 28 through flue gas delivery trunk 27, by exhaust gas volumn and the wind speed in exhaust gas volumn regulating gate 2, the 4 adjusting gas distribution flues 3, flue gas is evenly collected gather to main chimney flue 5 and entered the dry powder adsorption chamber, at the dry powder adsorption chamber, at first spray pulverized limestone uniformly and evenly mix, make harmful substance in the flue gas by the full and uniform dried absorption of drystone ashes with flue gas by drystone ashes powder spraying apparatus.Formulated (Bimscha) and (" air purifying process guide " CTALVFL that on August 28th, 1974 announced) standard and every scientific research and testing report on March 15th, 1974 by Germany " control of pollution act ", the every cubic metre of flue gas of baking bricks sprays into 300 milligrams of pulverized limestones can satisfy the air cleaning requirement fully.Therefore determine every day 50,000 of output calculate the discharging flue gases at 7047 every cubic metre/hour by excess air coefficient 3.Can satisfy the requirement of dusting fully with the existing facility that dust reaches about per minute 36g.At 2 meters/S of lime dried bean noodles absorption air inlet place's wind speed.The pulverized limestone of doing after adsorbing enters adsorption reaction section 9 with flue gas, and under the effect of deep bead 10, wind speed is reduced to 0.6 meter/S, and filters by 150 order screen packs 11, and most of adsorption particle and flue dust are piled up under dropping to deep bead 10 limits.The band dust flue gas entered cyclone reaction tower 16 after whole dried absorption was finished.Flue gas is in dry powder adsorption chamber course of reaction, and its harmful substance and the reaction of drystone ashes generate calcium chloride, calcirm-fluoride or calcium sulfate and so on product, finish the starting stage and handle.
The band dust flue gas at inlet 15 places of cyclone reaction tower 16 with after the vaporific alkali lye that alkali lye sprayer unit 14 sprays mixes, under the effect of centrifugal blower 13, enter cyclone reaction tower 16 at a high speed from top, in tower, become the full and uniform mixing of eddy flow shape, make reaction more fully to decompose the harmful substance in the flue gas, water smoke in the flue gas that rotates at a high speed gets rid of under action of centrifugal force to the cylinder inner wall of cyclone reaction tower 16 downwards, be agglomerated into cigarette water and flow to alkaline reaction pond 18 along cylinder inner wall, the droplet that the moisture fog dust gas that descends condenses to normal temperature during through 150 order water smoke screen packs 17 drops onto in the alkaline reaction pond 18, because the photosynthetic roofing layer 19 of sunlight board is adopted at the sealing top in alkaline reaction pond 18, ultraviolet ray in the sunlight can see through in the sunlight board direct projection pond, utilizes photosynthetic response to decompose the part harmful substance.
Dust all in the flue gas precipitate into slurry in alkaline reaction pond 18, when depositing to certain thickness, slurry just alkali lye is put into 22 decomposition reactions of acid liquid reaction pond by pipeline 20, remove meeting the harmful substance that acid is decomposed, and carry out neutralization reaction and generate neutral liquid and continue to utilize.When a cover reaction unit cleaning maintenance, can manipulate another set of reaction unit and continue not stop transport commentaries on classics, reach the continuous operation purpose.
Through above lime dried bean noodles absorption, alkali lye water smoke condensation reaction, photosynthetic response is decomposed, after the alkali acid solution body neutralization reaction, nuisance in the flue gas existing about 86% has obtained handling, the nuisance about about 14% of remaining stable chemical performance, this part flue gas is with after the air that replenishes from acid liquid reaction pond 22 top replenish air mouths 23 mixes, 24 are handled through the pyrolytic that carries out that flue gas input house steward 25 delivers to brickkiln by centrifugal blower 26 through the gas outlet, so recycling, the harmful substance in the flue gas is all removed the most at last.
