A set of gas-liquid part flow arrangement is equipped in self-circulating anaerobic reactor of the invention, it by guide shell, gas gathering mask, block liquid set and form.Guide shell is stood vertically in tank center；Tank body is separated into two reaction chambers, guide shell up and down and passes through from gas gathering mask center of top and be tightly connected with it by pyramid type gas gathering mask, and gas gathering mask bottom edge and tank skin are tightly connected, and is provided with material path close to bottom edge periphery, expects pipe is taken under material path, then connect deflector；It blocks liquid and covers and entangle guide shell below gas gathering mask, bottom edge and guide shell are tightly connected；A circle venthole is provided on blocking the water conservancy diversion barrel in liquid set.The biogas that gas gathering mask is collected into when operation enters guide shell through venthole, rises and releases reactor；Feed liquid is blocked liquid set and is blocked, and guide shell can only be entered from bottom, then ascends into the second reaction chamber top, then declines and enters the first reaction chamber through charge tube, completes feed liquid one circulation.This reactor is not only suitable for the fermentation raw material of low suspended matter, is also applied for the fermentation raw material of high suspended matter.
Description
Technical field
The present invention relates to a kind of anaerobic digestion reaction vessels
Background technique
Anaerobic digestion is the process combined by a variety of anaerobic bacterias by organic matter transformation at biogas.The quality of mass transfer directly affects
The efficiency of anaerobic digestion, in order to improve transformation efficiency, most anaerobic reactors are all provided with feed liquid agitating device.Wherein absolutely mostly
Number is stirred using mechanical stirring or pump circulation, this can consume a large amount of energy.In order to reduce energy consumption, scientific research personnel tries benefit
Feed liquid is stirred with the biogas that anaerobic digestion generates, successfully develops IC (Internal Circulation) reactor
But IC reactor is improved by up-flow anaerobic sludge blanket, it is only applicable to low outstanding as up-flow anaerobic sludge blanket
Processing of the processing of floating object organic liquid waste for high suspended matter organic liquid waste, now still without good self-loopa stirred reactor
Occur.
Summary of the invention
The task of the present invention is provide the self-circulating anaerobic reactor that a kind of structure is simple, at low cost.It is stirred with solving power
Mix high energy consumption, maintenance difficult problem.Even making fermentation raw material with high suspended matter organic liquid waste, also it is able to achieve feed liquid self-loopa and stirs
It mixes, achievees the purpose that energy conservation, efficient stable operation.
Self-circulating anaerobic reactor of the invention is that a set of gas-liquid part flow arrangement is installed in tank, it is by guide shell, gas collection
It covers, block liquid set composition.Guide shell is upright in tank center；Pyramid type gas collection covers in the middle part of tank tank body being divided into the first reaction chamber
(under) and the second reaction chamber (on)；Guide shell is passed through from gas gathering mask center of top, and is tightly connected with it；Gas gathering mask bottom edge and tank
Wall is tightly connected；Periphery close to gas gathering mask bottom edge is provided with material path, and expects pipe is taken under material path, connects deflector under charge tube；
It blocks liquid and covers and entangle guide shell below gas gathering mask, set bottom and water conservancy diversion barrel are tightly connected；It is same on blocking the water conservancy diversion barrel in liquid set
A circle venthole is opened on one horizontal line.When reactor, which feeds intake, to be run, the biogas that the first reaction chamber generates is collected by gas gathering mask
Under cover, after accumulation reaches venthole upper limb, then more biogas collect will enter guide shell from venthole, then float into the
Reactor is discharged from biogas pipe in two gas chambers.First reaction chamber feed liquid is blocked liquid set and is blocked, and cannot enter guide shell from venthole,
Guide shell can only be entered from bottom, be flowed up under biogas drive, into the second reaction chamber top, then sedimentation is passed through downwards
Expect that hole enters the top of the first reaction chamber, then drop to bottom, completes a feed liquid circulation.As long as reactor normal gas producing,
Ceaselessly feed liquid can be pushed ceaselessly to recycle.
Self-circulating anaerobic reactor of the invention has following features compared with IC reactor: (one) structure is simple.The present invention
Reactor be only provided with a set of gas-liquid part flow arrangement；IC reactor is provided with two sets of three phase separators.(2) range of DO is big.
Reactor of the invention realizes the systemic circulation of entire reactor feed liquid；IC reactor only realizes following for the first reaction chamber feed liquid
Ring.(3) have a wide range of application.Reactor of the invention had both adapted to the fermentation raw material of low suspended matter, also adapted to the fermentation of high suspended matter
Raw material；IC reactor can be only applied to the fermentation raw material of low suspended matter.
Detailed description of the invention
Fig. 1 is the schematic diagram of self-circulating anaerobic reactor.
Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and detailed description.
Self-circulating anaerobic reactor of the invention is that a set of gas-liquid part flow arrangement is arranged in tank, it is by guide shell [4], collection
Gas hood [5] blocks liquid set [6] composition.The vertical heavily fortified point of guide shell [4] stands on tank center, until second from 60~100cm above tank bottom
The water level line of reaction chamber [3] or near, 20~60cm of diameter.Tank body is divided into the first reaction in middle part by pyramid type gas gathering mask [5]
Room [2] and the second reaction chamber [3], guide shell [4] is passed perpendicularly through from gas gathering mask center of top, and is tightly connected；Gas gathering mask [5] bottom
Side and tank skin [14] are tightly connected, and the material path of 8 or more bore 30cm is provided with close to gas gathering mask bottom edge periphery, under connect same bore
Long 50cm charge tube [8], connect a deflector [9] under charge tube [8].It blocks liquid set [6] and entangles guide shell below gas gathering mask [5]
[4], set bottom and guide shell [4] are tightly connected, and block liquid set [6] diameter greater than guide shell [4] diameter 20cm or more；Block liquid set [6]
Suitable for reading to push up 60cm lower than gas gathering mask [5], bottom is lower than gas gathering mask [5] bottom edge 30cm.Block in liquid set [6] with gas gathering mask [5] bottom
A circle venthole [7], the size of each venthole [7]: the isosceles three of high 5cm, bottom 3cm are opened on the guide shell [4] of side same level
It is angular；3~5cm of spacing between 2 holes.When reactor, which feeds intake, to be run, feed liquid is pumped into the first reaction chamber by feed pipe [1]
[2] middle part, the biogas of generation, which is collected by gas gathering mask [5] and is stored in cover, assigns water level line [10] (for the first gas chamber [11]).This
More biogas collect will enter guide shell [4] by venthole [7] again afterwards, then float into the second gas chamber [12], then from natural pond
Reactor is discharged in tracheae [13].The feed liquid of first reaction chamber [2] is blocked liquid set [6] and is blocked, and cannot enter water conservancy diversion from venthole [7]
Cylinder [4], guide shell [4] can only be entered from bottom, the second reaction chamber [3] top are flowed up under the drive of biogas, so
After be lowered through expects pipe [8] into the first reaction chamber top, then drop to pot bottom, complete the circulation stirring of feed liquid.Extra
Feed liquid overflows to discharge nozzle [16] discharge.
