the utility model provides an anaerobic reactor effluent degassing unit, includes inside hollow degasser, be provided with inlet tube and outlet pipe on the degasser, the inlet tube is located the upper portion of degasser, the height of outlet pipe is less than the height of inlet tube, the top of degasser is provided with the blast pipe.
Further, the degasser is cylindrical as a whole.
Further, a liquid level sensor is arranged at the bottom in the deaerator.
Furthermore, an automatic regulating valve for controlling the flow rate of the liquid is arranged in the water outlet pipe.
Further, a circulating water taking pipe is arranged at the lower part of the deaerator.
Further, a manhole for inspection is provided at a lower portion of the deaerator.
Further, a slag discharge pipe is arranged at the bottom of the degasser.
The utility model has the advantages that: inside liquid in the anaerobic reactor flowed into the degasser through the inlet tube, mixed gas rose under the buoyancy of water in the liquid to discharge through the blast pipe, liquid after the degasification passed through the outlet pipe and discharged to next treatment facility, because highly being less than of outlet pipe the height of inlet tube, so the effectual degasification has been realized basically to outlet pipe exhaust liquid, thereby makes the utility model discloses the effectual jam problem that leads to mud calcification and other various pipelines after anaerobic granules in the liquid contacted with the air of having solved.
