Description

A kind of biological flue gas fermentation unit
?
Technical field
The present invention relates to a kind of biological flue gas fermentation unit.
Background technology
At containing a certain amount of deleterious H in the biological flue gas that produces in the biological flue gas engineering 2S gas particularly carries a large amount of water vapour in the biological flue gas that produces by middle temperature or high-temperature anaerobic fermentation in the biological flue gas engineering, this gas can form hydrosulphuric acid with water vapour, quickens pipeline in the engineering, valve, the corrosion of under meter etc. or obstruction.In addition, the H in the biological flue gas 2S burning back generates SO 2,It can combine with the water vapour in the products of combustion and generate sulfurous acid, makes combustion equipment or generating set produce corrosion, and atmospheric environment is polluted, and influences HUMAN HEALTH.Therefore, Environmental Protection in China standard strict regulation: when utilizing the biological flue gas energy, H in the biological flue gas gas 2S content must not surpass 20mg/m3.But H in the biological flue gas gas that produces in the anaerobic fermentation process 2The content of S is higher than this environmental protection standard far away, so in the biological flue gas engineering, remove H 2The S link that is absolutely necessary.
Existing biological desulphurization in the biological flue gas engineering all is additional desulphurization reactor or a thionizer etc. outside anaerobic reactor or anaerobic fermentation tank, in reactor or tower, pack into and adhere to the filler of microorganisms such as desulfurization bacterium, from the H that contains of desulphurization reactor or the rising of thionizer bottom 2The biological flue gas of S is at the filler place, and under microbial processs such as desulfurization bacterium, and contacts and biochemical reaction, H take place from the desulfurated circulating water of top spray is reverse 2S is oxidized, generates elemental sulfur, thereby realizes biological desulphurization.But this additional desulphurization reactor or thionizer are systems independently, and microorganisms such as desulfurization bacterium environment is very responsive to external world, the biochemical environmental requirement height of its growth, along with constantly carrying out of desulfurization, in desulphurization reactor or thionizer and the change of the biochemical environment of desulfurated circulating water, cause sweetening effectiveness significantly change to occur, and sweetening process is not easy control; The sulphur simple substance that produces in the biological desulphurization process stops up or covers the filler of the confession microorganic adhesion in desulphurization reactor or the thionizer easily, and this elemental sulfur obstruction or covering because of generating in the reaction process, in desulphurization reactor or thionizer, be difficult to remove, cause sweetening process to be interrupted; Additional bio-desulfurization device outside anaerobic reactor or fermentor tank, increase the equipment investment cost of engineering, and in the operation process, owing to adopt the desulfurated circulating water spray, methods such as adjusting such as pH value had both needed to provide power, had increased extra energy consumption, need manual operation again, so improved the operation cost of engineering; Owing to additional bio-desulfurization device, just increased the floor space of biological flue gas engineering.
Summary of the invention
The problems referred to above that the present invention is produced aborning for additional special bio desulfurizer in the present biological flue gas engineering of solution, a kind of biological flue gas fermentation unit has been proposed, when using this device to carry out the biological flue gas fermentative production, producing, utilizing microorganism to realize hydrogen sulfide is oxidized to elemental sulfur in the gas storage integral anaerobic fermentation unit, thereby do not needing additional special bio desulfurizer (as the biological desulphurization tower) promptly can play effect the biological fermentation gas desulfurization.
Biological flue gas fermentation unit of the present invention, comprise anaerobic fermentation tank, the top of described anaerobic fermentation tank is a double membrane structure, and the upper space in anaerobic fermentation tank is provided with microorganism carriers such as being used to adhere to desulfurization bacterium, and the anaerobic fermentation tank top is connected with the air access equipment.
Described carrier can be used in the different shape that adheres to microorganisms such as desulfurization bacterium for plane laminate structure or wavy shaped configuration or the helix structure etc. that have mesh, and being preferably the plane laminate structure that has mesh can be attached thereto with desulfurization bacterium preferably.Described carrier is made by corrosion resistant material, as being made for organic polymer PVC, PE etc., microorganisms such as desulfurization bacterium can be directly adhered at the mesh place of described carrier, also can microorganism be adsorbed on the materials such as porousness adsorption stuffing such as porous ceramics, porous volcanics earlier, and then it is attached on the carrier.
Described carrier can be to be horizontally fixed on the perisporium of anaerobic fermentation tank, also can be on the perisporium that is fixed on anaerobic fermentation tank of low dip, be preferably to make attached to the microorganisms such as desulfurization bacterium on the carrier on the perisporium that is horizontally fixed on anaerobic fermentation tank and fully contact with the hydrogen sulfide of rising.
The inlet mouth of described air access equipment preferably is positioned at the below of carrier, can guarantee that like this micro-air that is fed and the hydrogen sulfide that fermentation produces fully react.
Biological flue gas fermentation unit of the present invention, biological desulphurization is directly carried out in the inside that can be implemented in anaerobic fermentation tank or reactor in use, the operation that does not need additional special-purpose complex external equipment such as biological desulphurization tower to carry out desulfurization has significantly reduced biological flue gas construction investment cost.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
Biological flue gas fermentation unit of the present invention, its integral body is that a top is the anaerobic fermentation tank 4 of double membrane structure 1, upper space in anaerobic fermentation tank 4 is provided with microorganism carriers 3 such as being used to adhere to desulfurization bacterium, and described carrier 3 is the plane laminate structure that has mesh on the perisporium that is horizontally fixed on anaerobic fermentation tank; Be provided with air access equipment 2 on anaerobic fermentation tank, the inlet mouth of this air access equipment is positioned at the air storage chamber space of the below of carrier layer, proferment feed liquid 5 tops.In the biological flue gas fermenting process, carrier is positioned at the air storage chamber space, top of fermented liquid liquid level, because the biochemical environment of this fermentation is relatively stable, desulfurization bacterium that adheres on the carrier such as thiobacillus denitrificans, microorganisms such as thiobacillus thiooxidans can be kept normal biological metabolism in this yeasting, the hydrogen sulfide containing biological flue gas that produces in the fermentor tank like this rises from raw material liquid level below and passes the microbe carrier layer, simultaneously, feed micro-air in the air storage chamber, biochemical reaction just can take place being attached with on the microorganism carriers such as a large amount of desulfurization bacteriums, generate elemental sulfur, thereby reach the purpose of desulfurization, sulphur can concentrate on the carrier after for some time, only need this moment the duplicature external mold above air storage chamber to beat gently, the elemental sulfur that is given a shock just can come off, and enters in the fermented feed liquid, and together discharge with tunning the back, therefore back to nature also can guarantee the lasting constant of sweetening process.
