Description
Technical field
The utility model relates to anaerobic reactor, especially relates to a kind of strengthening internal-circulation anaerobic reactor adopting the tangential water distribution of ejector.
Background technology
Anerobic sowage treatment technology is the metabolic process utilizing anaerobion, when without the need to oxygen supply, is small-molecule substance, produces a certain amount of clean energy biogas simultaneously organic pollutant decomposition and inversion macromolecular in sewage.Wherein internal-circulation anaerobic reactor (Internal Circulation, IC) be that Dutch Paques B. V. researches and develops successful third generation high efficiency anaerobic reactor the eighties in last century, be at s-generation anaerobic reactor, the basis of up flow anaerobic sludge blanket reactor (UASB) develops.Compared with UASB, the advantage such as IC has that volumetric loading is high, small accommodation area, capacity of resisting impact load are strong, thus at home, outer high concentration wastewater treatment field more and more applied.
But existing IC reactor has its weak point, be in particular in following two aspects: one is that the water inlet flow velocity of the water distribution system being positioned at reactor bottom is too little, strength of turbulence is inadequate, thus cause and fully can not mix with the returned sluge of the mud and internal recycle downtake that are positioned at reactor bottom into water, constrain the COD clearance of system; Two is that system toggle speed is slow.At the debugging initial stage, because gas production rate is little, in upcast, air lift phenomenon can not be formed, thus there is no internal recycle truly.
Utility model content
The purpose of this utility model is the problem solving above-mentioned proposition, provides a kind of cloth water flow velocity to block greatly, not easily, a kind of strengthening internal-circulation anaerobic reactor adopting the tangential water distribution of ejector that mass-transfer efficiency is high.
The purpose of this utility model realizes as follows: have reactor tank body, jet flow water distributor, bottom triphase separator, upper strata triphase separator and effluent weir is provided with from the bottom up successively in described reactor tank body, also have for allow sewage enter reactor tank body water inlet pipe and for allowing the rising pipe of tail water outflow reactor tank body after process, described water inlet pipe connects with the feed-water end of the connection jet flow water distributor being positioned at reactor tank base, be communicated with the bottom of reactor tank body, described jet flow water distributor is arranged tangential.
Further prioritization scheme is, above-mentioned a kind of strengthening internal-circulation anaerobic reactor adopting the tangential water distribution of ejector, the suction end of described jet flow water distributor connects the downtake in described reactor tank body, described downtake is connected with the bottom of knockout drum, in described knockout drum, form negative pressure.
Further prioritization scheme is, above-mentioned a kind of strengthening internal-circulation anaerobic reactor adopting the tangential water distribution of ejector, described bottom triphase separator is communicated with knockout drum by the first upcast, and described upper strata triphase separator is communicated to knockout drum by the second upcast.
Further prioritization scheme is, above-mentioned a kind of strengthening internal-circulation anaerobic reactor adopting the tangential water distribution of ejector, and described gas-liquid separation tank top connects biogas pipe.
Further prioritization scheme is, above-mentioned a kind of strengthening internal-circulation anaerobic reactor adopting the tangential water distribution of ejector, and in described reactor tank body, upper strata has effluent weir, and effluent weir connects rising pipe.
Further prioritization scheme is, above-mentioned a kind of strengthening internal-circulation anaerobic reactor adopting the tangential water distribution of ejector, is also provided with effluent recycling pump between described water inlet pipe and effluent weir, and by its through effluent recycling pipe.
Further prioritization scheme is, above-mentioned a kind of strengthening internal-circulation anaerobic reactor adopting the tangential water distribution of ejector, described jet flow water distribution utensil is one or more.
Advantage of the present utility model: 1, device of the present utility model is that sewage enters the bottom of reactor tank body by the water inlet pipe be connected with jet flow water distributor feed-water end.Its due to ejector exit velocity control enough large, thus provide enough strength of turbulences, simultaneously because jet flow water distributor is arranged tangential, its water outlet can form a kind of eddy flow effect, so sewage fully can mix with the returned sluge in bottom mud in tank and downtake after entering tank body, mass-transfer efficiency is greatly improved.Not only water distribution exit velocity is large, thus not easily blocks; And water inlet can form eddy flow effect, thus mass-transfer efficiency is high;
2, because the suction end of jet flow water distributor is connected with downtake, so form negative pressure in knockout drum, under the effect of negative pressure, the mud in bottom triphase separator and triphase separator region, upper strata enters knockout drum by upcast, then be back to tank base by downtake under gravity, thus form internal recycle very soon.Due to the getter action of ejector, even if this internal recycle also when debugging initial stage biogas output is very little can be formed fast and be strengthened.Owing to there being certain negative pressure in knockout drum, thus internal recycle can be formed fast and be strengthened; Therefore in sewage, organic pollutant removal rate can reach more than 90%.
