Abstract
The invention discloses a kind of Novel internal circulation anaerobic reactors, it includes water distributor（1）, inner loop pipeline system（2）, water inlet（3）, anaerobic reactor main body (4), water outlet（5）, gas outlet（6）, organic wastewater is from water inlet（3）Enter anaerobic reactor main body（4）, pass through water distributor（1）Organic wastewater is uniformly distributed, in reactor process, passes through inner loop pipeline system（2）It is recycled in being formed, generated biogas passes through gas outlet（6）Output, treated organic wastewater is from water outlet（5）Discharge, a kind of Novel internal circulation anaerobic reactor, inner loop pipe-line system are improved, the ratio of height to diameter of reactor is reduced, reduces the power energy consumption of intake pump, saves operating cost, reduce the upflow velocity of organic wastewater simultaneously, avoid the loss of granule sludge.
Description
Technical field
The present invention is a kind of Novel internal circulation anaerobic reactor, belongs to anaerobic digestion process field.
Background technology
Internal-circulation anaerobic reactor is connected in series by 2 layers of UASB reactors, internal automatic cycle, it is not necessary to additionaling power, it is general
The reflux of logical anaerobic reactor is realized by external pressurized, and internal-circulation anaerobic reactor using the biogas that itself is generated as
The power of promotion recycles to realize in mixed liquor, it is not necessary to and pump forced circulation is set, saves power consumption, but since interior cycle is detested
Oxygen reactor ratio of height to diameter is larger, on the one hand increases the power consumption of intake pump, improves operating cost, on the other hand accelerates
The flow rate of climb will cause granule sludge to be lost in if three phase separator is dealt with improperly.
Invention content
Present invention is generally directed to the above problem, in provide that a kind of ratio of height to diameter is small, biomass is more, degradation efficiency is high novel
Circulation anaerobic reactor.
To achieve the above object, the present invention takes following technical proposals：
A kind of Novel internal circulation anaerobic reactor, water inlet（3）With anaerobic reactor main body（4）Bottom is connected, water distributor（1）It is high
In water inlet（3）, in water distributor（1）Top installation inner loop pipeline system（2）.
A kind of Novel internal circulation anaerobic reactor is further inner loop pipeline system（2）By multiple circulation lines
（7）It is formed in parallel.
A kind of Novel internal circulation anaerobic reactor is further circulation line（7）By cone-shaped hood（8）, riser
（9）Sedimentation pipe（10）Composition.
A kind of Novel internal circulation anaerobic reactor is further cone-shaped hood（8）Above two cone-shaped hoods form dirt
Mud decanting zone.
The novel advantageous effect of the present invention has：By the parallel connection of circulation line, the ratio of height to diameter of reactor is reduced, is reduced
The upper speed of organic wastewater, avoids the loss of granule sludge, increases biomass, improves the efficiency of reactor, simultaneously
Reduce the energy consumption of feed pump, save operating cost.

Fig. 1 is the structure diagram of the present invention.
Fig. 2 is the structure diagram of circulation line.
Symbol description：
1. water distributor, 2. inner loop pipeline systems, 3. water inlets, 4. anaerobic reactor main bodys, 5. water outlets, 6. gas outlets, 7.
Circulation line, 8. cone-shaped hoods, 9. risers, 10. sedimentation pipes.
Specific embodiment
The invention will be further described with example below in conjunction with the accompanying drawings：
As shown in Figure 1 and Figure 2, a kind of Novel internal circulation anaerobic reactor, water inlet（3）With anaerobic reactor main body（4）Bottom phase
Even, water distributor（1）Higher than water inlet（3）, in water distributor（1）Top installation inner loop pipeline system（2）.
Preferably, circulating pipe system（2）By multiple circulation lines（7）It is formed in parallel.
Preferably, circulation line（7）By cone-shaped hood（8）, riser（9）Sedimentation pipe（10）Composition.
Preferably, cone-shaped hood（8）Above two cone-shaped hoods form sludge settling areas.
The present invention reduces the ratio of height to diameter of reactor, reduces the upper flow velocity of organic wastewater by the parallel connection of circulation line
Degree, avoids the loss of granule sludge, increases biomass, improve the efficiency of reactor, while reduce the energy of feed pump
Consumption, saves operating cost.
The present invention is described by way of example above, but the present invention is not limited to above-mentioned specific embodiment, all bases
The scope of protection of present invention is belonged in any changes or modifications that the present invention is done.
