Description
Technical field
The utility model relates to anaerobic biological treatment equipment, relates in particular to internal-circulation anaerobic reactor.
Background technology
Anaerobic biological treatment is a kind of important method of biological wastewater treatment technology.Internal-circulation anaerobic reactor is a kind of high-effect anaerobic reactor that Europe was developed in the eighties in last century, is one of third generation high efficiency anaerobic reactor of developing on UASB reactor basis.Owing to having the outstanding advantages such as aspect ratio is large, upflow velocity is fast, organic loading is high, internal-circulation anaerobic reactor is processed organic usefulness and has been surpassed UASB reactor, and has been applied in actual waste water treatment engineering.Internal-circulation anaerobic reactor is in fact overlapping being in series of UASB reactor (II chamber) by the EGSB reactor of bottom (I chamber) and top, two-stage triphase separator in reactor can effectively be detained biomass, overcome the UASB reactor deficiency that granule sludge easily runs off in the situation that fluid surface upflow velocity is higher, thereby make reactor remove organism ability, significantly improved.
But, in very long use procedure, find that internal-circulation anaerobic reactor exists water distribution inhomogeneous, easy heavy deposition material, gas-liquid separation scarce capacity, processed complex is difficult for forming the drawbacks such as standardized production.
For this reason, Chinese invention patent (patent No. ZL200610000917.7) discloses a kind of multi-phase internal circulating anaerobic reactor, be in reactor cell body, arrange with division plate separate, parallel-series connects several internal circulating anaerobic reaction chambers with two-stage reaction district and corresponding air-lift tube, effuser, return line, gas-liquid separator, triphase separator, sealing gland, the gas-liquid separator of reaction chamber or be connected in parallel on same biogas vent pipe, or output respectively.Entrance at reaction chamber is established flow deflector, in the bottom of air-lift tube, has air lift device.Owing to being stage treatment, organic biochemical degradation process is just distributed in different reaction chambers carries out, this is beneficial to different types of anaerobion flora and independently in reaction chamber, is growing, air lift device internal recycle has strengthened the lifting dynamics of liquid, has good water conservancy fluidised form and mixing pattern, good microbial separate stage, an advantage such as good sludge retention ability, organic loading is high, volume is little.But, although this invention discloses the independently concept of anaerobic reaction chamber, so because it is still the integrated design, only at inside reactor, be divided into several anaerobic reactions chamber, therefore its one-piece construction is still very huge, be difficult for carrying and dismounting, cost increases, and not energy-conservation.
Therefore, those skilled in the art is devoted to develop a kind of standard module that is easy to be processed into, and is easy to carrying and dismounting, reduces costs, energy-conservation, solves the internal-circulation anaerobic reactor of the problems such as the inhomogeneous and gas-liquid separating power deficiency of water distribution simultaneously.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide and is easy to be processed into standard module, is easy to shipment, energy-conservation, the uniform internal-circulation anaerobic reactor of water distribution.
For achieving the above object, the utility model provides a kind of internal-circulation anaerobic reactor, comprises housing, and described housing is the column that cross section is equilateral hexagon.The column of equilateral hexagon is easy to be made into standardized module, and its shape is easy to shipment, and it is in parallel to be easy to a plurality of internal-circulation anaerobic reactors, makes full use of space.
In better embodiment of the present utility model, described internal-circulation anaerobic reactor is a plurality of parallel connections, and the internal-circulation anaerobic reactor cross section of described a plurality of parallel connections is cellular.Polynuclear plane is the internal-circulation anaerobic reactor formation in parallel due to equilateral hexagon column shape, this kind of structure only need will be made each reactor parallel join of standardized module, because the shape of equilateral hexagon can be leaned on by Bian Bianxiang, make not stay between reactor in parallel gap, take full advantage of space, make the reactor after parallel connection form a set of integral device, because every cover standardized module all carries water distributor and gas-liquid separator, self forms a set of complete internal circulation system, therefore, those skilled in the art form a whole set of anaerobic treatment equipment after can designing a plurality of standardized module parallel connections according to need of production, meet the different needs.
In another better embodiment of the present utility model, described internal-circulation anaerobic reactor comprises triphase separator, biogas-lift pipe, return line, water distributor, gas-liquid separator.Described water distributor is located at described internal-circulation anaerobic reactor inner bottom part, and described gas-liquid separator is located at described housing upper end, and described return line upper end is connected with described gas-liquid separator, and lower end is connected with described water distributor.Described triphase separator is two, is respectively one-level triphase separator and the top secondary triphase separator of being located at middle part in described internal-circulation anaerobic reactor, and described internal-circulation anaerobic reactor is divided into upper and lower two-stage reaction chamber; Described biogas-lift pipe is two, and upper end is connected with described gas-liquid separator respectively, and lower end is connected with described two triphase separators respectively.Because cloth water area is little, water distribution very evenly fully; Due to enough large gas-liquid separator, be not easy again the inadequate and phenomenon of feeling suffocated of generating ability.
Described inner walls top, be positioned at place, described secondary triphase separator top and be provided with overflow groove.
Also comprise overflow weir, described overflow groove is by regulating the height of described overflow weir to switch to water outlet or crossing water.Because single structure of reactor diminishes, reactor upper water-out canal is reduced to directly and routs up from honeycomb outside overflow, can become water channel by regulating height of weir plate to close monolateral water outlet.
Described water distributor is the equilateral hexagon matching with described internal-circulation anaerobic reactor shape of cross section.It is even that the water distributor of employing equilateral hexagon can reach water distribution, do not stay the technique effect at dead angle.
Described water distributor is the whirlwind-type water distributor that diameter is less than described housing cross section.Adopt whirlwind-type water distributor that liquid stream is moved in a circle in the same direction in reactor, form eddy flow, the omnibearing stirring of liquid in the device that induces reaction, produces eddy current, makes mud be not easy deposition, has increased the mass transfer effect of mud and organic waste water.
The utility model also provides internal-circulation anaerobic reactor, by 3,7 or 19 internal-circulation anaerobic reactors, is formed in parallel.Each internal-circulation anaerobic reactor is made standardized module.19 module compositions the reactor of 19 meters of diameters; 7 standard modules have formed the reactor of 11.5 meters of diameters, 3 module compositions the reactor of 9 meters of diameters, with 16/20/24/30 high computational, its reactor volume can be contained the main market requirement, and for too small volume, UASB steel reinforced concrete pool body more can mate perfection.
