The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, so that those skilled in the art can understand the utility model and being implemented better, but illustrated embodiment is not as to restriction of the present utility model.
According to the process of sewage disposal, foul smell produces the source and mainly is divided into sewage disposal system and sludge treating system.Odor source in sewage disposal system mainly is distributed in sewage water place, pretreatment, primary treatment and filter back washing liquid, Treatment of Sludge supernatant etc., and the stirring of aeration tank and oxygenation also can the generating portion foul smell.Foul smell in sludge treating system source is distributed in mainly that mud is concentrated, sludge dewatering and mud after anaerobic digestion are stacked, the outward transport process, due to unstable mud is compressed, shear action, produce protein-based biopolymer, it decomposes a large amount of foul smell of generation.Different processing structures can be selected different gas collecting modes, collecting the most effective mode for the foul gas of pond body class structures is to carry out the pond body to add a cover, carry out airtight, take a breath by centrifugal blower again, foul gas is pumped in controlling device process, the mode of adding a cover can be selected the method for light weight, corrosion resistant fluorine-carbon fibre membrane inflatable, stretching type or brace type.Workshop and pump house class structures can carry out the collection of point source foul gas by the choice set gas hood, deliver to sewage treatment plant of the present utility model foul gas odor removal and carry out purified treatment.
The foul gas of collecting is delivered to the air inlet 13 of air scrubber 1 through blower fan, because sectional area becomes large, gas flow rate diminishes at air inlet 13 places, for follow-up gas distribution and reaction provide advantage, and foul gas density ratio air is little, moves up in inlet plenum 16, enters reaction zone.Reaction zone comprises the support tray 15 of being combined with the tower wall of packing layer 14 and lower floor thereof.Filler type selecting: owing to not containing dust and tar in foul gas, dirty stifled phenomenon is not serious, and consider corrosion resistance and price, so selection ceramic packing, filler is mainly as conversion zone, its pallet uses the porous plate that can guide gas flow of improved, on the support frame structure that level is shelved on air scrubber is combined.Pallet 15 is simultaneously as air-distribution device, this air-distribution device is necessary for improving absorption efficiency, except make between packing layer and shower 19 main jet that forms drench district's smoke distribution evenly, pallet 15 makes also that the interior mobile absorption liquid of foul gas and shower 19 or cleaning solution form on pallet liquid film zone is fully contacted.Foul gas and cleaning solution are after packing layer 14 places contact, cleaning solution enters inlet plenum 16 because of Action of Gravity Field, discharge from sewage draining exit 11, part cleaning solution is combined with foul gas and is formed water smoke continuation rising, enters gas-liquid separation layer 17, and gas-liquid separation layer 17 takes off mist plate 171 for the single-stage "the" shape pottery of transversely arranged a plurality of vertical placements, spacing is the 20mm left and right, in water smoke, moisture is trapped within pottery and takes off in mist plate 171, and gas is discharged by exhaust outlet, enters heterogeneous exchange system.Long-term operation gas-liquid separation layer may produce fouling, needs situation stifled according to dirt to open the scavenge pipe 18 of being located at gas-liquid separation layer top, and cleaning ceramic takes off the gas-liquid separation layer that the mist plate consists of.Air scrubber has good removal effect for foul gas, can select different cleaning solutions according to the variety classes of foul gas.Can effectively remove NH
3, H
2All kinds of odorous substances such as S, alcohols, ethers, hydro carbons, clearance can reach 90%.
Be drawn into the foul gas that comes and pass through successively from bottom to top each deodourizing medium polymeric plate, complete the gas-solid exchange on polymeric plate surface and volatile substance, and carry the deodorizing factor and discharge, the gas that carries the deodorizing factor of discharging exchanges with foul gas generation gas phase in air again, and heterogeneous reaction has improved the efficient of deodorizing.Be suitable for little odour environment or use as the deodorizing two stage treatment, and the polymeric plate of high concentration has the smell compensating action.Heterogeneous exchange system not only can be used for further removing odorant after air scrubber, and the odorous substance clearance is reached more than 95%, really reaches the effect that purifies air, can also be used for separately little smelly environment, simple to operate, easy for installation, good deodorization effect.
The import 21 of heterogeneous exchange system also can be integrated in a switch board 24 by pipeline with outlet 23, is convenient to unified by-pass cock operation.
The above embodiment is the preferred embodiment that proves absolutely that the utility model is lifted, and protection domain of the present utility model is not limited to this.Being equal to that those skilled in the art do on the utility model basis substitutes or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
