Description
Technical field
The utility model relates to waste gas purification environmental protection field, and the compound bio filter that specifically a kind of biomembrane filled tower (pond) and biofiltration tower (pond) are in series is applicable to purify and handle low concentration complex effluvium gas and industrial waste gas.
Background technology
At present, the biological treatment that is used for purifying low-concentration foul gas and industrial waste gas mainly contains biological washing method and biofiltration process.Biological washing method claims biosorption process again, its device is called biological scrubbing tower, claim biological purification tower again, mass-transfer efficiency is low, the microorganism of generation cycle length is difficult to existence, the generation surplus sludge volume is big, complicated, the relative more high shortcoming with operating cost of construction cost of start-up routine but this method exists.Biofiltration process comprises bio-trickling method and biological filter process, and its device is called bio-trickling filter and biofilter, and the former is specially adapted to single industrial waste gas purifying and deodorizing, but relatively poor to water-insoluble organic exhaust gas treatment effect; Latter's shortcoming is that reaction condition is wayward, and relatively poor to the adaptability of inlet gas concentration, floor space is big, need carry out humidification processing etc. to filler or waste gas.Therefore they all are restricted in the purification of complicated ingredient foul gas and industrial waste gas.
The purpose of this utility model is purification and the handling problem that solves complicated ingredient life foul gas and industrial waste gas, for the purification and the processing of complicated ingredient life foul gas and industrial waste gas provides a kind of wide adaptability, cost is low, simple in structure, treatment effeciency is high, good purification, NEW TYPE OF COMPOSITE biofiltration device simple to operate.Handle the back with regard to free from extraneous odour as foul gas that destructor plant discharged through this device, the energy qualified discharge.
The purpose of this utility model realizes by following technical scheme.The compound bio filter is composed in series by biomembrane filled tower (pond) and biofiltration tower (pond).The air inlet that its biomembrane filled tower comprises, gas outlet and liquid distributor have biofilm packing at the biomembrane filled tower inner filling; Biofiltration tower comprises air inlet and gas outlet, at the biofiltration tower inner filling natural organic fiber biologic packing material is arranged, and forms the biofiltration bed.The tandem compound of described biomembrane filled tower and biofiltration tower, its tandem compound mode can be stacked series connection, also can be the block form series connection; It is tower that said biomembrane filled tower and biofiltration tower can be respectively, and also can be the pond formula.Said biofilm packing only plays the bio-carrier effect, nutraceutical material can not be provided in the described biomembrane filled tower, that filler comprises is organic and inorganic, mineral and metal matter filler, biofilm packing can be an individual layer, it also can be multilayer, interlayer can be separated by with plate washer, filler can be single filler simultaneously, also can be two or more compounded mix.Described waste gas in biomembrane filled tower evenly enters through the bottom of air inlet from biomembrane filled tower, discharge from biofilm packing top of tower gas outlet through biofilm packing, enter the biofiltration tower that is in series with biomembrane filled tower by the air inlet that is connected with the gas outlet; From the biomembrane filled tower top spray, shower can connect shower nozzle to said liquid by sparge pipe, and spray liquid is discharged from leakage fluid dram by liquor collecting system from the bottom of biomembrane filled tower through filler, and circulates by water pump; Used liquid can be water, bacterium liquid and nutrient solution.Described in biofiltration tower the gas after biomembrane filled tower is handled feed biofiltration tower from the biofiltration tower bottom through air inlet, gas is discharged through exhaust outlet from biofiltration tower top by filler, the top vent of biofiltration tower can be fully uncovered, part is uncovered, or for the column passage as chimney of different shape.Described filler in biofiltration tower adopts natural forestry, cultural solid fiber organic matter, and as wooden bamboo wood material, bark, peach-pit, stalk, corn ear etc., being shaped as can be block, dendritic, strip, clastic etc.; Described filler can be an individual layer, also can be multilayer, and interlayer can be separated by with plate washer, and filler can be a homogenous material simultaneously, also can be the combination or the mixture of two or more material.When described biomembrane filled tower and biofiltration tower block form polyphone, the liquid of bottom directly enters the liquor collecting system of biomembrane filled tower as spray liquid by the passage that links to each other through leakage fluid dram in biofiltration tower, perhaps enters the spray liquid circulatory system by pump.
The utility model has the advantages that the advantage that combines biological washing method, bio-trickling method and biofiltration process, combination by biomembrance process and biofiltration process, eliminated shortcoming separately, disposal ability and efficient have been improved greatly to complex effluvium gas and industrial waste gas, and have structure and simple to operate, biological inoculum and filler and be easy to get, start advantage easy, stable, that treatment effeciency is high, the device fabrication cost is low, the exhaust-gas treatment cost is low, be specially adapted to the processing of complex effluvium gas and industrial waste gas.
Description of drawings
With reference to Figure of description the utility model is elaborated.
Accompanying drawing 1 is a complex biological filter structural representation of the present utility model.
The specific embodiment
Compound bio filter of the present utility model, it is formed by the biomembrane filled tower that is in series (pond) 1 and 2 two part organic assembling of biofiltration tower (pond), biomembrane filled tower 1 can stackedly link to each other with biofiltration tower 2, also can be to link to each other side by side.In biomembrane filled tower 1, be filled with biofilm packing 6, waste gas enters biomembrane filled tower 1 through air inlet 3, and when waste gas is absorbed when the biofilm packing 6 and decomposes, the waste gas after biomembrane filled tower 1 is handled 4 enters biofiltration tower 2 further biodegrades through the gas outlet.Sparge pipe 5 in biomembrane filled tower 1 can connect shower nozzle filler 6 and the waste gas that enters filler 6 are sprayed and humidification, and the liquid of spray circulates by pump 10, and the liquid of consumption can replenish by adding liquid.When waste gas through biomembrane filled tower 1 degraded and humidification, enter biological the mistake in the tower 2 by air inlet 7 in the bottom of biofiltration tower 2, waste gas further is adsorbed during by biologic packing material 9 and decomposes, waste gas after biofiltration tower 2 is handled by biofiltration tower 2 in the exhaust outlet 8 at top be discharged into atmosphere, the atmosphere of discharge has not had stink and has met atmospheric emission standard.In biofiltration tower 2, need not again filler and waste gas to be sprayed the humidification processing.
When the utility model was made, the filling surface growth had biomembrane to form biological cleaning processing bed, and biofilm packing layer 6 can be made individual layer, also can be multilayer, and interlayer can be separated by with baffle plate.Filler material in the packing layer 6 is for only playing the bio-carrier effect, nutrients not being provided, and these fillers can be the made organic filler of all kinds, inorganic filler, natural minerals filler and solid waste filler.Filler 6 can be single filler simultaneously, also can be two or more combined stuffing.
Described biologic packing material 9 can be made individual layer, also can be multilayer, and interlayer can be separated by with baffle plate.Filler material in the filler 9 is forestry, agricultural fibre solid organic matters, and as wooden bamboo wood material, bark, peach-pit, stalk, corn ear etc., being shaped as can be block, dendritic, strip, clastic etc.Filler 9 can be a homogenous material simultaneously, also can be the combination or the mixture of two or more material.
