Description
Technical field
The utility model belong to microorganism bed fillers and purification technology field, more specifically, it relates to a kind of
Bio-trickling filter elastic filler and bio-trickling filter.
Background technique
The mechanism of biological method purification organic exhaust gas is to be turned the organic composition in exhaust gas by metabolic activity using microorganism
It is melted into the process of simple inorganic matter (CO2, water etc.) and cell component.Due to gas, liquid (or surface of solids liquid film) it
Between organic concentration gradient and water-soluble effect, the pollutant in exhaust gas first has to by the mass transport process between gas, liquid,
Then it is degraded by microorganisms in the liquid phase, metabolite a part of generation is dissolved in liquid phase, and a part is as cellular material or carefully
Born of the same parents are metabolized the energy, are transferred to gas phase from liquid phase if some (such as CO2), the pollutant in exhaust gas is continuous by the above process
It reduces, to be cleaned.
Specific gaseous pollutant has its specific suitable treatment microbiologic population, can be into according to source of nutrition come point
The microorganism of promoting the circulation of qi state contaminant degradation can be divided into two class of autotrophic bacterium and heterotroph.Autotrophy mattress is primarily adapted for carrying out turning for inorganic matter
Change, such as nitrification, denitrification and sulfuric acid mattress can be leaned under conditions of no organic carbon and nitrogen ammonia, nitrate and hydrogen sulfide, sulphur and iron from
The oxidation of son obtains energy, carries out growth and breeding.But since the metabolic activity of autotrophy mattress is slower, it is adapted only to lower dense
Spend the processing of inorganic waste gases: heterotroph is to obtain energy and nutriment by the oxidative metabolism to organic matter, is being suitable for
Temperature, under the conditions of pH value and oxygen, they can complete the degradation of pollutant quickly: therefore, this quasi-microorganism is chiefly used in organic
The purified treatment of exhaust gas.Currently, being suitable for the gaseous pollutant of biological treatment mainly has ethyl alcohol, mercaptan, phenol, cresols, indoles, fat
Acid, acetaldehyde, ketone, carbon disulfide, ammonia and amine etc..
Bio-trickling filter is a kind of equipment purified using Purification biotechnology to gaseous pollutant.It is dripped in biology
Elastic filler is filled in filter tower, microorganism is in filler surface apposition growth and forms biomembrane.Microorganism is in biomembrane to have
Machine exhaust gas is carbon source and the energy, using the nutriment in circulation fluid as nitrogen source, carries out vital movement.A part of organic exhaust gas
It is converted into harmless water and carbon dioxide by the catabolism of microorganism, and provides energy for microorganism;Another part has
Machine pollutant is converted into the living matter of microorganism itself by anabolism.Biologic packing material made of being filled as elastic filler
Layer porosity, to factors such as the drag sizes of gas, the purification efficiency and effect of bio-trickling filter are had an important influence.
In the prior art, the Chinese patent that Authorization Notice No. is CN204582959U discloses a kind of for bio-trickling filter
It is dedicated without blocking filler comprising positioned at bottom inlet air distribution disk, be installed on the filler air inlet pipe of the inlet air distribution disk
And it is set in the hollow sponge filler stick outside the filler air inlet pipe.Inlet air distribution disk is the shell with hollow cavity, institute
The top surface wall body for stating shell is provided with multiple qi-emitting holes, and air inlet is provided on the side wall of the hollow cavity and is connected to gas inlet
Pipe.It is practical, and play the role of microorganism attachment and biofiltration is sponge filler.
But the hole of this filler filler is fine and closely woven, is easy to the case where blocking in actual use, seriously
When even cause the collapsing of packing layer, significantly impact the clean-up effect of bio-trickling filter.Therefore, how bio-trickling filter is improved
Filler, be urgent problem to be solved in the industry to reduce blocking, improve purification efficiency.

It is excessive, it easily causes and the purification of gas is not thorough；When spacing between cilium is less than 0.1 ㎜, then the gap formed or hole mistake
In tiny intensive, gas-flow resistance is big, is unfavorable for improving purification efficiency.
Further, the rope body is formed by several one threads are twisted.
The service life of filler is extended so that rope body is solid, durable by using above-mentioned technical proposal, without frequent
Replacement.
Further, the rope body is formed by two one threads are twisted, and the cilium is fixed between twisted yarn.
By using above-mentioned technical proposal, so that cilium is evenly distributed, gap size each other is uniform, to gas
Purification efficiency is high, good purification.
Further, the both ends of the rope body are provided with the connector being hung in bio-trickling filter for the body that will restrict.
By using above-mentioned technical proposal, have the function of facilitating installation and replacement elastic filler.
Further, the connector is the fixed ring for being fixedly connected on rope body end.
By using above-mentioned technical proposal, elastic filler can be hung by hook or iron nail etc., so that filling out
The attaching/detaching of material is simple and convenient.
Further, the cilium is the PVC fiber of linear, wave threadiness or zigzag shape.
By using above-mentioned technical proposal, different types of elastic filler can be produced, wave is linear or spiral is existing
The cilium of shape is conducive to increase the bond area of microorganism in elastic filler, improves unit volume filler and imitates to the purification of gas
Rate；PVC tenacity of fibre is good, and corrosion resistance is good, durable, using it as cilium, elastic filler long service life obtained,
Without frequently replacing.
The purpose of this utility model is to provide a kind of bio-trickling filter, has high to the purification efficiency of gas and purify
Thoroughly, the advantage without frequently being replaced to elastic filler.
To achieve the above object, the utility model provides following technical solution:
A kind of bio-trickling filter is filled with bio-trickling filter elastic filler described in any of the above embodiments.
By using above-mentioned technical proposal, when to the purification of gas, resistance is small, purification efficiency is high and purification thoroughly, to elasticity
The installation and replacement of filler are convenient, and without frequently replacement elastic filler.
In conclusion the utility model has the following beneficial effects:
1, based on body of restricting, cilium is set on rope body, so that the large specific surface area of elastic filler, it is attached to be conducive to microorganism
, while forming gap/hole hole each other after hanging and being connected, it is less prone to blocking and packing layer collapse and situation；
2, fixed ring is fixedly installed in the end of rope body, has been significantly greatly increased to elastic filler installation convenience；
